Title: Electrophotographic receptor
Inventor: MARUSHIMA GIICHI
IPC: G03G5/00
Filed: 1980-05-23
Abstract: PURPOSE:To prevent deterioration in the performance of a receptor and make the receptor highly sensitive, reducible in size and fit for high-speed copy by forming an insulating layer on the photoconductive layer contg. SeTe. CONSTITUTION:On electrically conductive support 21 photoconductive layer 22 contg. SeTe is formed, and on layer 22 insulating layer 23 of fluorine-contained resin, polycarbonate resin, polyester resin or the like is formed to manufacture receptor 2. Layer 23 has low abrasiveness and high resistance, can retain electrostatic charges, and transmits light to whch layer 22 is sensitive. The surface of receptor 2 is uniformly charged by means of discharger 3. For example, it is positively charged when layer 22 is an n type semiconductor, and receptor 2 is negatively charged simultaneously with exposure through image P. Uniform exposure is then carried out to increase the surface potential difference between negative light part L and positive dark part D, and part D is developed with toner T to obtain an image free from fog and having high density. Since layer 23 protects layer 22, the durability is improved.

Title: Automatic eliminating device for undesired signal of recorder
Inventor: FUJIMOTO HIDESUKE
IPC: G11B20/04
Filed: 1981-05-07
Abstract: PURPOSE:To improve the operating performance in the active mode of a recorder, by providing an undesired signal selecting and amplifying means, detecting the undesired signal through the rectification and the shaping of waveform and controlling the working of an undesired signal eliminating filter. CONSTITUTION:An undesired signal selecting means 1 consists of a filter 11 and an amplifier 12. An undesired signal rectifying and shaping means 2 consists of a rectifying circuit 21, a limiter circuit 22 and a time constant circuit 23. An undesired signal detecting means 3 detects the undesired signal with the output of the means 2 and comprises a comparator. The level setting e0 of the means 3 is done in correspondence to the undesired signal elimination factor which is required for a noise reducing circuit (NR) device. Thus the presence or absence of the undesired signal is detected automatically, and at the same time the malfunction due to the instantaneous high band signal caused by the musical component can be avoided by the circuit 23. A control means 4 is turned on and off by the output of the means 3 to automatically control the working of an undesired signal eliminating filter 5. In such way, the operating performance can be improved when the recorder is active.

Title: Head supply liquid type refrigerator for cooling a plurality of temperature chambers
Inventor: HARA TAKESHI
IPC: F25B43/00
Filed: 1994-02-28
Abstract: PURPOSE:To perform operation at a suction pressure suitable to temperature in a refrigerator by connecting a gas outlet of a low pressure liquid receiver to a gas outlet of a gas cooler for high temperature and a suction inlet of a high temperature compressor by means of a high temperature suction pipe and connecting a gas outlet of a gas cooler for low temperature to a suction inlet of a low temperature compressor by means of a low temperature suction pipe. CONSTITUTION:High temperature, high pressure refrigerant gases discharged from a high temperature compressor 3a and a low temperature compressor 3b are made to join each other and flow into a condenser 8, in which the gases are liquefied to form high temperature, high pressure liquid. A flow control valve 9 reduces pressure to form a low temperature, low pressure gas-liquid two phase flow, which flows into a low pressure liquid receiver 2. Herein, the gas phase and the liquid phase are separated from each other in the receiver 2, and the low temperature, low pressure liquid is sent to coolers 1a, 1b by using head. Low temperature, low pressure gas generated by gasification in the cooler 1a for high temperature together with the low temperature, low pressure gas in the low pressure liquid receiver is sucked by the high temperature compressor 3a through the high temperature suction pipe 5a. The low temperature, low pressure gas evaporated and gasified by the cooler for low temperature 1b is sucked through a low temperature suction pipe 5b by the low temperature compressor 3b.

Filed: 1992-03-27
Abstract: PURPOSE:To enable a stable head positioning control by smoothly performing the pull-in of a head to a track center without being blocked by an integral element even when the switch from a seek control to a track follow-up control is performed before the track center. CONSTITUTION:When an access instruction is received from a host device, a head is moved to a target track location by performing a speed control of an actuator 38 based on the position signal determined from servo information of a servo head 34 in a servo control part 40 and the head is followed up by performing the pull-in of the head to the center location of the target track by switching to a track follow-up control when the head speed becomes below a prescribed value just before the target location. For an integration circuit 15 which started the integral operation when the switch to the track follow-up control is performed, the fact that a position signal becomes zero by the attainment to the track center is detected by an integration reset circuit 42 and an integral reset is performed.

Title: Device for drive-in pipe of wire rod colier
Inventor: MATSUDA YASUNORI
IPC: B21C47/04
Filed: 1982-04-22
Abstract: PURPOSE:To select an optimum drive-in angle easily, by making a drive-in pipe freely movable in advancing and retreating along the axial direction of the pipe and freely turnable in the vertical direction by setting a virtual point as a turning center on the axial line of the tip side of the pipe. CONSTITUTION:A drive-in pipe 6 is adjusted to an optimum drive-in angle by a drive-in angle adjusting device 7. That is two screwed shafts 30, 31 are rotated by prescribed number of turns by a motor 32, then a sliding bed 34 moves in the same direction along the axial direction of the screwed shafts 30, 31. At this time, the moving quantity of a nut engaging with the shaft 31 is smaller than that of the other nut because the screw pitch of the shaft 31 placed on the side of a coiling drum device 1 is smaller than that of the other shaft 30. Said difference of moving quantity makes the pipe 6 turn around the virtual point O set as a turning center on the axial line of the tip side of the pipe 6. The virtual point O is set on the prescribed position between inner and outer diametral frames 4, 3. The optimum drive-in angle is detected and controlled by a controlling box 33.

Abstract: PURPOSE:To increase the weighing-capacity accuracy of a negative mixture, and incease the mean discharge capacity and the reliability of an alkaline battery by preparing the said negative mixture by granulating mixture of an amalgamated zinc used as a negative active material and a gelling agent by using polyvinyl pyrrolidone as a binding agent. CONSTITUTION:In the figure, a granular negative mixture 1 is prepared by using PVP as a binding agent, a positive mixture 3 is made of a mixture consisting of silver oxide powder and carbon used a a conductive agent, and a separator 3 principally consists of a cellulose system matter. The variation of the maximum and the minimum weights of a negative mixture having an almost equalized mean weight, is reduced by using the granular negative mixture 1 prepared according to this invention. This is because amalgamated zinc powder and gelling- agent powder are bound together and behave as one particle in the invention, and because the fluidity of the granular negative mixture 1 is notably high. As a result, the mean discharge capacity of the battery is increased, and the reliability of the battery is enhanced due to the increased weighing-capacity accuracy of the negative mixture 1.

Abstract: PURPOSE:To produce a thin metallic film having electromigration resistance by mixing vapor of an alkyl compd. contg. Al as a constituent element with vapor of a metallic halide to form a thin metallic film. CONSTITUTION:A semiconductor substrate is set in a reaction chamber. While the substrate is heated to about 260 deg.C, the chamber is evacuated for about 30min to remove moisture adsorbed on the surface of the substrate.

Thus, the potential at an output terminal F3 reaches the high level of the phi2 at a high speed. Thus, the upper limit of the operating frequency of the shift register is improved and the output amplitude is increased.
