摘要： An amplification type solid-state image pickup device of the invention includes a plurality of photoelectric conversion sections 10 each having an embedded photodiode 1 and a transfer transistor 2, a switched capacitor amplifier section 20 whose input side is connected to a charge detection node 8 to which output terminals of the plurality of photoelectric conversion sections 10 are connected in common, and a current amplification section 21 connected between the switched capacitor amplifier section 20 and a vertical signal line 9. Signal charge from the plurality of photoelectric conversion sections 10 is converted into voltage by the switched capacitor amplifier section 20, and the converted signal is current-amplified by the current amplification section 21 and outputted to the vertical signal line 9. Thus, a less-noise, high-quality image can be obtained while a reduction of the pixel size is achieved by reducing the number of transistors per pixel.

摘要： An electrically addressable passive device for registration, storage and/or processing of data comprises a functional medium (1) in the form of a continuous or patterned structure (S) which may undergo a physical or chemical change of state. The functional medium (1) comprises individually addressable cells (2) which represent a registered or detected value or are assigned a predetermined logical value for the cell. The cell (2) is provided between the anode (3) and cathode (4) in an electrode means (E) which contacts the function medium in the cell and causes an electrical coupling therethrough, the functional medium having a non-linear impedance characteristic, whereby the cell (2) directly can be supplied with energy which effects a change in the state of the cell. In a method for electrical addressing of the passive device wherein the addressing comprises operations for i.a. detection and registration as well as further operations for writing, reading and switching of a logical value assigned to the cell, electric energy is applied directly to the functional medium of the cell in order to change its state and hence effect an addressing operation. Use in optical detector means, volumetric data storage devices or data processing devices.

摘要： An optical gate array includes a photodetector, an optical modulator, and a reflecting structure arranged therebetween. The photodetector, the optical modulator, and the reflecting structure are composed of semiconductor materials. The photodetector includes an MQW (Multi Quantum Well). The reflecting structure is constituted by a distributed Bragg reflector formed by alternately stacking semiconductor layers having different refractivities. The photodetector and the optical modulator are arranged to receive light from different directions. The modulation characteristics of the optical modulator are controlled by the intensity of light radiated on the photodetector. The reflecting structure connects the photodetector and the modulator electrically and isolates lights radiated on both parts. A plurality of optical gates, each constituted by the photodetector, the optical modulator, and the reflection structure, are two-dimensionally arranged.

摘要： An optically isolated N-channel MOSFET driver turns on a MOSFET device in response to an optical input signal to drive a load. The turn-on time of the MOSFET is enhanced by a current boost circuit. As the MOSFET transcends to an on state and delivers current to the load, the voltage across the device diminishes and causes the current boost circuit to become inactive thus reducing to zero the current drain consumed by the current boost circuit. A photovoltaic array maintains the MOSFET operation. An optically isolated SCR is respondent to the absence of a light signal to turn off the MOSFET. Furthermore, the optical decoupling of the SCR, between the gate and source of the MOSFET device, is arranged to provide enhanced noise immunity. A voltage clamping circuit coupled between the gate and source of the MOSFET device provides additional protection to the device from large over voltages.

摘要： A system for testing a fiber-optic component with infrared radiation is provided. The testing system has a source of infrared radiation, an optic coupler, a detecting circuit, and an analog tape recorder. The optic coupler directs the infrared radiation onto the fiber-optic component. The detection circuit is electrically connected to the tape recorder. The detection circuit has an amplifier, a potentiometer connected in parallel to the amplifier, and a photoelectric transducer connected in series to the amplifier. These components are mounted on a non-conductive board. A power source supplies voltage and is connected to the amplifier. The circuit operates by having the photoelectric transducer sense the infrared radiation emitted from the tested fiber-optic component and convert the radiation into an electrical signal. The amplifier then amplifies the electrical signal to the voltage necessary for driving the tape recorder.

摘要： An optical switch in which states are defined by dynamic charge storage, rather than contention resolution, and which switches using pulsed radiation having a wavelength somewhat longer than the exciton wavelength in a SEED diode. The switch does not exhibit or need bistability but switches at a relatively low energy as compared to S-SEEDS switched at the exciton wavelength.
