摘要： PURPOSE:To prevent the adhesion of flying ash to a waste gas duct and the like by solidifying the ash and exclude the bad affection to a bag filter by diluting waste gas by a method wherein the waste gas from a melting furnace is cooled insantaneously before introducing it into the bag filter to shorten a time, in which gaseous flying ash in the waste gas is in the molten condition thereof. CONSTITUTION:In a plasma melting furnace 1, in which the melting treatment of incinerating ash is effected in a melting furnace 4, waste gas, generated from the melting furnace 4, is diluted by cooling air, by 5-50 times, and is introduced into a bag filter 14 whereby the mixture of salts such as NaCl and the like, which are the principal constituents of flying ash contained in waste gas, passes the molten condition thereof instantaneously in one breath and is changed from gas into solid instantaneously and, therefore, the adhesion of flying ash to the inner wall surfaces of a waste gas duct 12 and/or a gas cooler becomes hard and bad 1 affection to the bag filter can be excluded by diluting the waste gas.

摘要： PURPOSE:To easily realize the queuing of reserved recording by providing a reserved recording circuit which executes reserved recording of broadcast in accordance with preset details of reservation and also outputs a reserved recording operation signal. CONSTITUTION:A reserved recording circuit 1 starts, in accordance with reserving information stored therein, the recording of a broadcast at the reserved time and also generates a reserved recording operation signal S1 to send it to an initialization circuit 3. After a while, when the reserved recording information end time of the reserving information stored in the reserved recording circuit 1 has come, the reserved recording circuit 1 stops running of the tape for completing the reserved recording of the broadcast. Accordingly, upon completion of the reserved recording, a user is capable of setting the queu of the broadcast recorded by the reversed recording mode only by rewinding the tape until a display value of an electronic counter 2 is reset to zero.

摘要： PURPOSE:To rapidly and surely search a program reserved and recorded in simple operation by instructing the program searching by the user after completion of recording the program according to stored reserving information. CONSTITUTION:A reservation circuit 1 is started for its recording operation at the time of reserved hour and also a reserved recording operation signal S1 is generated, which is then given to a reserved recording starting position storage circuit 3. At this time, a tape position information signal S2 from a tape position detecting circuit 2 is stored by the circuit 3 according to the signal S1. When a program searching instruction circuit 4 is operated by the user after completing the reserved recording, a program searching instruction signal S3 is generated, and is given to the circuit 3, a program searching starting circuit 6 and a program searching ending circuit 7. A rewinding signal S4 is given to a rewinding circuit 5 by the circuit 6 upon receipt of the signal S3 so as to start rewinding the tape. Then, upon coincidence of tape position information stored by the circuit 3 and an output of the circuit 2, the rewinding is stopped by the circuit 5. By this method, the reserved and recorded program can rapidly and surely be searched in the simple operation.

摘要： PURPOSE:To set a proper white level at either of white and black parts. CONSTITUTION:A sample holding circuit 31 is set in a sampling state where a white level signal is outputted in accordance with the change of a picture signal when an analog switch 42 is closed. When the switch 42 is opened, the circuit 31 is set in a holding state where the level of the picture signal inputted at the end of a period of the immediately preceding sampling state. When the position of a reading subject is changed to a white part from a black part, the output of a differentiation circuit 33 has the large positive value. Thus a comparator 34 sends out a set signal S to set a flip-flop 35. As a result, the switch 42 conducts. Meanwhile the output of the circuit 33 has the large negative value when the position of the reading subject is changed to a black part from a white part. Thus the comparator 34 sends out a reset signal R to reset the flip-flop 35. As a result, the switch 42 is cut off.

摘要： PURPOSE:To satisfactorily read the symbols after the light reflected regularly from the symbol surface is made incident on a detection element by resetting a peak holding level by means of the reset signals which are produced for each symbol reading action in the prescribed frequency. CONSTITUTION:A peak holding circuit 20 is connected with a reset circuit 30 which resets the peak holding level with the reset signals produced for each symbol reading action in the prescribed frequency. The output of a synchronizing signal generating circuit 40 which produces the synchronizing signal in response to the start of an electrical scanning operation of an optical image is applied to the circuit 30. Then the peak holding level of the circuit 20 is reset in response to the synchronizing signal. Thus the output signals of a detecting element increase temporarily owing to the regular reflected light and the gain of a variable gain amplifier 10 is extremely reduced. Even under such conditions, the gain of the amplifier 10 can be quickly returned to the value corresponding to the quantity of light received by the detecting element by a resetting action. As a result, the symbols can be satisfactorily read.
