Title: Formation of image
Inventor: FUJII TETSUYA
IPC: G03G15/05
Filed: 1981-12-22
Abstract: PURPOSE:To form an image which is free from a secondary fault without using a charger, by using a composite photoreceptor consisting of an insulator layer, a photoconductive insulator layer and a transparent conductor layer successively from the side of the surface to irradiate an optical image to the surface of a photoreceptor. CONSTITUTION:A photosensitive plate 1 consists of a transparent supporter 2, a transparent conductive lyer 3, a photosensitive layer 4 and an insulated layer 5. The supporter 2 can serve also as the layer 3. In this example, it is required just to use a photoconductive insulator as the layer 4 with no need for the charge retaining properties or continuous conductiveness. This process can reduce the limit to materials for the layer 4. Furthermore, there is no limit for the materials of the layer 4 in terms of the deterioration or the wear since the layer 4 is out of direct contact with air or the component parts in a cleaning stage. At the same time, no secondary fault due to a product obtained by corona discharge is produced since no charger is needed unlike a conventional case.

Title: Voltage division fet gate bias control circuit using trimmable resistor
Inventor: HIRAOKA SHIGEMI
IPC: H03F3/16
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a gate bias control circuit of an FET for which a bias point is stable even after adjustment capable of hot trimming by using a trimmable resistor for at least one resistor of bias resistors. SOLUTION: A power supply terminal l is connected through an ammeter to the side of a power source Vdd and the power supply terminal 2 is connected to the ground side of the power source Vdd. Then, the bias resistors R1 and R2 are trimmed so as to make a drain current match a design target value. Since the drain current is continuously adjusted because the adjustment of a resistance value by the laser trimming is continuous and infinite, the gate voltage Vg of the FET Q1 is optimally adjusted. At the time, the trimmable resistors capable of the hot trimming are used as the bias resistors R1 and R2. Thus, since the resistance value is adjusted while measuring the drain current, optimum gate bias control is made possible.

A failure managing data base 23 registers the occurrence of the failure at the terminal. Moreover, the controlling part 22 and the data transmitting and receiving part 21 report the ID of the terminal at which the failure is caused to a preliminarily registered destination in detecting that the failure is caused at the terminal.

Title: Taking-up method for composite power cable
Inventor: SAKAGUCHI YASUO
IPC: H02G1/02
Filed: 1994-08-08
Abstract: PURPOSE:To introduce a wire-stranded body smoothly and laying a cable smoothly by selecting the stranding pitch of the core wires of an electric cable and the trunk diameter of a taking-up drum in the way a gap G defined by a specified expression becomes external diameter dp of strips to be compounded or narrower. CONSTITUTION:When a composite power cable is coiled on a drum, since a power cable is composed of stranded wires, the cable core becomes deficient in length in the outside circumference and becomes excessive in length in the inside and the deficiency and the excess occur repeatedly and reciprocally. When a gap G defined by an expression I becomes the outer diameter or near the outer diameter dp of strips, dropping of the strips occurs. Consequently, to prevent the stranded strips to be compounded from the standing gap of the electric power cable, the stranding pitch of the core wires of the power cables and the trunk diameter of the drum are so selected as to make the gap G be the outer diameter dp of the strips or smaller. As a result, the core wires of the power cable are prevented from dropping or being loosened.

Title: Synchronism detector of pwm inverter
Inventor: SUZUKI TATATOMI
IPC: G01R29/18
Filed: 1982-11-27
Abstract: PURPOSE:To synchronize a PWM inverter with a different power source by shaping the voltage waveform of the PWM inverter through a waveform shaping circuit consisting of an LPF, amplifier, and limiter, then multiplying both voltage waveforms by each other. CONSTITUTION:When a three-phase PWM inverter is used, transformers 2 and 4 are utilized to put the inverter 3 to be synchronized 90 deg. out of phase with a reference inverter 1. Then, obtained voltages different in phase by 90 deg. are inputted to individual waveform shaping circuits 10, whose rectangular wave outputs are inputted to a multiplier 21, whose output is passed through a filter 22. The filter 22 generates a negative or positive output according to whether the inverter to be synchronized lags or leads in phase to the reference inverter. The output of a phase regulator 24 has the phase difference between both inverters, so the frequency of the PWM inverter 3 to be synchronized is varied. When both inverters are coincident in phase with each other, a synchronism detector 25 outputs a synchronizing signal to attain the synchronization.

Title: Display element
Inventor: KOJIMA HIDETSUGU
IPC: G02F1/015
Filed: 1993-08-02
Abstract: PURPOSE:To provide the display element capable of controlling transmitted light by a change in absorption end. CONSTITUTION:A display section 1 consists of a heterojunction superlattice structure alternately laminated with first semiconductor thin films 2 consisting of GaAs and second first semiconductor thin films 3 consisting of AlxGa1-x in a transverse direction. The absorption end of this display section 1 is determined by the film thicknesses of the second semiconductor thin films 3 which are potential barriers. The electrostatic potential of only the first semiconductor thin films under transparent electrodes 5 arranged to every other first semiconductor thin films 2 increases when a voltage to make the transparent electrodes 5 negative is impressed between the transparent electrodes 5 and a common electrode 6. The state that the width of the second semiconductor thin films 3 is substantially widened is then attained. The absorption end in such a case shifts to a high frequency side. Such shift signifies that the wavelength of the light transmittable through the display section 1 changes.

Title: Protective device of semiconductor device
Inventor: MATSUMOTO KAZUTAKE
IPC: H01L27/088
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To enable realizing protection ability higher than or equal to the conventional case by using a smaller area without increasing manufacturing process, in an element structure protecting a semiconductor device from surge of static electricity or the like. SOLUTION: When surge of static electricity or the like is applied from the outside a drain region generates avalanche breakdown. A channel region under a gate electrode 440 turns to a high potential state where difference of voltages of a drain region 400 and a well potential supplying region 430 are divided by resistance between the drain region 400 and the well potential supplying region 430. This high potential state of the channel region constitutes a current flowing path due to a bipolar constitution of an NPN type. At this time, a drain contact 402 divides a current into two parts to source contacts 412 and 413 which have equal resistance component. Thereby the drain contact and the respective source contacts are linearly positioned, and the heating value at a drain end existing on a source region side is reduced.

Filed: 1990-08-06
Abstract: PURPOSE:To surely remove residual toner even when the residual toner has a small particle size by removing the residual toner one the surface of an image carrier by a brush member which rubs the surface of the image carrier. CONSTITUTION:A higher bias voltage than a bias voltage impressed on the brush member 11 is impressed on a collecting roller 14 from a power surface 15, so that the toner 2 remaining on the brush 11a is collected to the peripheral surface of the roller 14. Then, a scraping member 16 is allowed to press-contact to the circumference of the roller 14 which collects the toner 2 by a pressing means 17 such as a spring, etc., so that the toner 2 is scraped from the periph eral surface of the roller 14 by the member 16 and carried by a toner carrying coil 18. Next, a cleaning agent 21 is supplied to the peripheral surface of the roller 14 by a cleaning agent supply means 20. The toner 2 collected by the roller 14 is easily scraped from the peripheral surface of the roller 14 by the member 16, and the toner 2 is prevented from being accumulated on the periph eral surface of the roller 14. Therefore, the toner 2 adhering to the brush 11a is stably collected by the roller 14 over a long period.
