Title: Photodetector
Inventor: OZAKI YUZO
IPC: H04N5/335
Filed: 1987-02-04
Abstract: PURPOSE:To relieve restrictions against applying photodetectors to copying machines, faxcimile machines and so forth and facilitate designing small equipment by a method wherein a plurality of electrode layers are successively built up on a substrate so as to face each other with an insulating film between and an amorphous silicon thin film is deposited on the exposed end surface of each electrode layer. CONSTITUTION:Individual electrode films 12, a glass system insulating film 13, a common electrode film 14 and a glass system insulating film 15 are successively formed on a substrate 11 made of alumina ceramics or the like by a thick film baking method. After the respective layers including the substrate 11 are cut and polished, amorphous silicon thin films are deposited on the end surfaces of the respective electrodes 12 and 14 by a method such as CVD, sputtering and glow discharge. The photodetector formed like this has an end surface type structure and a space factor can be improved. With this constitution, by combining the photodetectors with an array type light source, the sizes of copying machines, faxcimile machines and so force can be reduced easily.

Title: Electrophotographic recording method
Inventor: KOBAYASHI TAKESHI
IPC: G03G15/00
Filed: 1986-02-06
Abstract: PURPOSE:To prolong the life of a photosensitive body by transferring a toner on a photoconductive layer of the photosensitive body to a counter electrode roll temporarily to make it unnecessary to control exactly the gap between the recording medium and the toner and facilitating managing and carrying the recording medium. CONSTITUTION:By optical scanning, a negative electric charge having a polarity opposite to that of the positive electric charge of the toner in a dark part is charged from an electrode E1 to the toner in the bright part of a photoconductive layer 1c. The attractive Coulomb force is applied to this negatively electrified toner from a counter electrode roll 6, and the toner is temporarily transferred to the counter electrode roll 6. Since the counter electrode roll 6 is provided with an insulating layer 6a, the negative electric charge of the toner transferred to the surface is kept stably attracted without being neutralized and is moved in accordance with rotation of the counter electrode roll 6. This toner is transferred to a recording medium 2 by a transfer means 3 in the position where it is brought into contact with the recording medium 2. Since the transfer means 3 is biased to a positive potential, the toner keeping the negative potential is transferred easily.

Abstract: PURPOSE:To mix and reduce the noise of the Lch (channel) signal and the Rch signal to ensure the extremely excellent acoustic noise reducing effect by securing the conducting state for the both output when the input signal is in the non-source state or the monaural source state of the stereo signal. CONSTITUTION:When both the Lch and Rch signals applied to the 1st and 2nd input terminals 1 and 2 are in the stereo source state, the amplifying signal is delivered from differential amplifier 5 to be rectified (6) and delayed. As a result, switching circuit 8 is opened to give the non-conducting state between output terminal 3 and 4. In other words, the input signal is delivered 3, 4 under the stereo state. In case the signals applied to terminal 1 and 2 are in the non-source state or the monaural source state between the stereo signals, the conducting state is secured between output terminal 3 and 4. Thus, the noise is mixed and reduced between the Lch signal and the Rch signal. As a result, the extremely excellent acoustic noise reducing effect can be obtained under the stereo reception state of the weak electric field in particular.

Abstract: PURPOSE:To provide a heater of simple structure, whereby an object to be heated which is accommodated in the internal space can be heated at a constant temp. CONSTITUTION:A crystalline highpolymer substance and electroconductive particles are mixed together and kneaded under appllication of a heat, and crushed into pellets after cooling, and shaped by a die in which a pair of metal foils are installed to form a PTC composition 2 in which electrodes 5, 5 are provided. In this PTC composition 2 bridged by irradiation with gamma-rays, an internal space 4 is provided in such a way that its axial direction extends approx. in the direction perpendicular to the electric conducting path for the current, and thereby a heater 1 is formed. An object to be heated is set in the internal space 4, and on the electrodes 5, 5 a voltage is impressed of a magniture at least twice as large as the voltage value at which the resistance value for appearance of the PTC characteristics is going to increase rapidly and the current going to decrease. The electric conducting path for the current is branched by the internal space 4, and the current density in the part extending in the axial direction of the internal space 4 increases. A high temp. zone of steady value is formed in the axial direction of the internal space 4, which is thus supplied with a constant heat efficiently even though the voltage and/or ambient temp. has varied.
