摘要： PURPOSE:To surely read a symbol with high accuracy in a wide read range by reducing satisfactorily a light source light on the symbol face. CONSTITUTION:By a second condensing lens 13 of two light beams L1, L2 passing through a light selection and transmission member 12, an image is formed in different positions of a one-dimensional photoelectric converting element 15, and from a distance between these image formation positions, distance information corresponding to a read distance is obtained. Subsequently, based on this distance information, a first condensing lens 2 is displaced along its optical axis, so that a laser light L is reduced enough on the symbol face 8 thereby. In such a way, read of a bar-code can be executed surely and with high accuracy in a wide read range.

摘要： PURPOSE:To efficiently sell goods at customer's place at a high speed by storing at least a processing main body in a case which can be attached to a human body. CONSTITUTION:With respect to a bar code reader 1, a processing part main body A consisting of an illuminating means 11 which illuminates a code read face, a light receiving means 12 which receives the light reflected from the code read face, and a discriminating means 13 which discriminates a code, a memory 14, and a battery 15 are stored in a case 2 set to an arm part 10 by a belt 3. Since at least the processing part main body A is stored in the case 2 which can be attached to the human body in this manner, a user is prevented from having his hands full of an enclosure by a conventional handy device, and he takes goods with his one hand and brings them to the vicinity of the case 2 to read the code stuck to goods and receives the price with his other free hand. Thus, the user efficiently sells goods at a high speed when selling goods at customer's places in a train.

摘要： PURPOSE:To permit prompt fusion of incineration ash even if the incineration ash including high melting point material is put into a fusion furnace directly as it is by generating high-temperature plasma arc on a continuous basis at a plasma torch installed in the fusion furnace. CONSTITUTION:A plasma torch 8 is lowered into a plasma arc furnace 5 to set the torch 8 at a preset distance to a corresponding pole 10. Then, incineration ash or captured dust is put into an ash hopper 12. The incineration ash put into the hopper 12 is put into the furnace 5. A cooled water supply device 27 is actuated to supply cooled water to the torch 8. Then, an air supply device 27 is actuated to supply air to the torch 8. A power supply device 4 equipped with a switching means from a.c. to d.c. applies d.c. voltage and gives high- energy pulse between the torch 8 and the corresponding pole 10, so that the heat energy of the plasma arc is given to the incineration ash. The heat energy of the plasma arc makes the incineration ash into fusion slag, which is taken out to an outside slag receiver 15.

摘要： PURPOSE:To enable a protective circuit to absorb surges applied to a semiconductor laser irrespective of their frequencies by a method wherein a diode whose conduction voltage is slightly higher than the oscillation voltage of the semiconductor laser is connected. CONSTITUTION:A Zener diode 2 is connected to a semiconductor laser 1 in parallel, and the laser 1 is driven by an alternate current voltage source 3 through the intermediary of a resistor 4. As the forward breakdown voltage of the semiconductor laser 1 is a hundred volts to several hundred volts, the Zener diode 2 of low yield voltage is used to clip a voltage applied to the semiconductor laser 1, whereby the semiconductor laser 1 can be protected against breakdown. Moreover, the Zener diode 2 functions as a low impedance the same as a conventional diode against a reverse voltage to clip a reverse voltage, so that it can protect the semiconductor laser 1 against a reverse surge voltage. Even if the Zener diode 2 is connected to a drive circuit in which a direct current voltage source 3' is employed in place of the alternate current voltage source 3, the same effect can be realized. When a capacitor is inserted in parallel with a diode, a protective circuit can absorb a surge of frequency higher than the switching frequency of the diode.

摘要： PURPOSE:To prevent flue gas from condensing in a bag filter and prevent the bag filter from getting corroded by operating a heater at the starting and finishing times of an incinerator. CONSTITUTION:A heater 30 is disposed in a flue gas purifying line on the upstream side of a bag filter 1 for filtering the flue gas from an incinerator. Also, an induced draft fan 3 is provided in the flue gas purifying line on the downstream side of the bag filter 1. Thus, flue gas is prevented from condensing in the bag filter 1 by operating the heater 30 at the starting and finishing times of the incinerator to treated flue gas quickly. Also, the bag filter 1 is prevented from corroding by dew condensation or the like, and harmful substances such as HCl, SOx, soot, heavy metal, dioxane can be removed from the starting and through finishing time of operation of the incinerator.

摘要： PURPOSE:To align the optical axis of a projection and a photodetection system and to eliminate variation in photodetection efficiency due to variation in the distance to an object by providing a hollow optical passage to the center part of a reflecting means and passing laser light which reaches a scanning means from a light source and laser light which reaches the object from a scanning means to the passage. CONSTITUTION:The reflecting means 4 is positioned very closely to the scanning means 3, the laser light 2 from the light source enters the scanning means 3 through the passage 4a at the center part of the reflecting means, and the laser light after being scanned passes through the passage 4a in the opposite direction from the incident light and reaches the object A. Further, an optical element is so arranged that the laser light which is scattered by striking on the object is reflected by the reflecting means 4 and photodetected by a photodetecting means 5 such as a photoelectric converting element. Consequently, the optical axes of the projection and photodetection systems are aligned without using any half-mirror and the variation in photodetection efficiency with the distance to the object A is eliminated.

摘要： PURPOSE:To obtain clear image by synchronizing plural image sensors with the invalid reading out section of these image sensors to have a common part and synchronizing them with the lighting timing of an illumination light source. CONSTITUTION:Each image sensor 2a-2x is respectively driven by associated image sensor driving circuits 1a-1x. The reference driving circuit 1a associated with the reference image sensor 2a outputs the frame synchronizing signal B of which cycle is the longest and repeats one frame operation by resetting with the aid of it's reset signal D. The reset output terminals of the other driving circuits 1b-1x are connected with the reset output terminal of the reference driving circuit 1a. As the result, the frame synchronizing signal B of each driving circuit 1b-1x agrees with that of the reference driving circuit 1a. Therefore, as the longer cycle than that of their minimum frame synchronizing signal is given to the driving circuits 1b-1x, the time of this cycle is transferred to the invalid picture element section and it illuminates the sensor in this section.

摘要： PURPOSE:To easily eliminate the information of an unnecessary part by making the latest bit of information outputted from an image sensor before a time when the completion of the input of a bit of image information is instructed as invalid in prescribed quantity. CONSTITUTION:When a switch 3 at an input instruction part 2 is turned on, a clock signal CK corresponding to the moving speed of a sensor cabinet 1 is outputted, and is given to an images sensor 7. The image sensor 7 converts a graphic image received an optical system 10 to an electrical signal, then sending it to a binarization circuit 8. The binarization circuit 8 supplies a binary-coded output to a shift register 11. The shift register 11 shifts the binary- coded signal in parallel and sequentially with the clock signal CK, but when the switch 3 at the input instruction part 2 is turned off, an input to a picture memory 12 is terminated at that timing. Consequently, the prescribed quantity equivalent to a vacant part out of the latest bits of information outputted from the image sensor 7 is not inputted to the picture memory 12, thereby the unnecessary information is easily eliminated.
