Title: Electrophotographic device
Inventor: YANO HIDEYUKI
IPC: G03G15/04
Filed: 1994-12-15
Abstract: PURPOSE: To control potential and to obtain aimed VD by allowing an exposure device arranged at a position after primary electrification and before development to emit light faintly and attenuating the potential of a photoreceptor. CONSTITUTION: Image exposure is performed to the image exposure device 3 by a laser scanner using the combination of a laser diode 34 and a polygon mirror 32, and an exposed part is developed with toner. A contact electrifying member 2 is an electrifying roller constiututed as three layers and pressured with the load of total pressure 5N from both ends of a core bar, and DC voltage is impressed on the member 2. In the case of a part corresponding to the part primarily electrified on the photoreceptor 1, a bias current is always allowed to flow in the laser diode 34 to perform the postexposure of an electrifying surface, thereby attenuating the surface potential of the photoreceptor 1. When an image signal is received, the current obtained by adding the bias current component to ordinary image exposure is applied to the laser diode 34, and the image exposure is performed.

Abstract: PURPOSE:To improve the optical conversion efficiency of an amorphous silicon solar cell by making a substrate temperature at the time of the formation of an N-type amorphous silicon layer higher than that at the time of the formation of a P-type amorphous silicon layer and an I-type amorphous silicon layer.

Filed: 1986-12-26
Abstract: PURPOSE:To display the actual size of a block editing area for an operator by computing the size of the block editing area from the number of lines from the beginning point line to the temporary terminal point line of the block editing area and a set up interlinear pitch. CONSTITUTION:After the beginning point of the block editing area is designated by an area designating operator 5, during a time before the terminal line is designated by the area designating operator 5 next time, a number of lines data to show the number of lines up to the temporary terminal line is generated by a number of lines data generating means 6.

Thus, the operator can know the size of the block editing area at that point of time by only operating the area designating operator 5.

Title: Resistance pressure sensitive type tablet
Inventor: YOSHIKAWA OSAMU
IPC: G06F3/045
Filed: 1990-11-19
Abstract: PURPOSE:To obtain invariably accurate information without correction nor adjustment by varying a reference value corresponding to an input voltage range even if contact resistances and conductor resistance values are different or vary to cause the variation of the input voltage range. CONSTITUTION:When a switching circuit 6 is connected to contacts X1-X5, an X-axial reference voltage is utilized as the voltage between X-axial auxiliary electrodes 20a and 20b. Therefore, the voltage applied between both-end electrodes 1a and 1b of an X-axial resistance plate 2 is varied as the contact resistances 12 and 13 of the electrodes 1a and 1b and the resistances of conductor resistances 16 and 17 are varied, and the X-axial reference voltage is also varied correspondingly. The contact resistances 23 and 24 of X-axial auxiliary electrodes 20a and 20b, conductor resistances 27 and 28, and a contact resistance Z are much smaller than the input impedance of an A/D converting circuit 10 and an arithmetic circuit 22, so they can nearly be ignored. Those characteristics are the same on an Y axis-side. Thus, the X-axial reference voltage is varied corresponding to the variation of the resistances at all times, so even if the voltage of position data is varied with the resistances, the voltage is automatically corrected and outputted.

Filed: 1991-10-31
Abstract: PURPOSE:To enable an irradiation light to be set to an optimum automatically by measuring light from a sample and then setting a specific irradiation light intensity and modulation amplitude based on each irradiation light intensity when the measured light output starts to be detected and saturation begins. CONSTITUTION:A computer 7 sets an AC output Jac of a modulation circuit 4 to 0 and a DC output Jdc to 0 according to an operation instruction for setting modulation from an operator. Then, Jdc is increased step by step, presence/ absence of an output of a photometry circuit 5 is checked, and then, if it is determined that there is an output, Jdc at that time Is stored as It. Furthermore, a difference between the last and current photometry outputs is obtained while increasing Jdc step by step, a timing when the difference becomes smaller than a specified value delta is detected, and then Jdc at that time is stored as Is. Then, an amplitude Jac of AC output of a circuit 4 is set as Jac= (Is-It)/2-d (d: a specified value) and a DC output is set as Jdc=(Is+It)/2, thus achieving a full-capacity measurement of a circuit 5 automatically.

IPC: H02P1/16
Filed: 1986-12-24
Abstract: PURPOSE:To prevent the occurrence of runaway state of immediately after a power supply for driving a motor is turned ON by controlling a switching means by an output signal from a flip-flop circuit using a motor-drive command signal and a signal from the power supply for driving the motor as input signals. CONSTITUTION:When the level of a current command signal S is close to zero when a DC power 2 for driving a motor is turned ON, an RS flip-flop circuit A positioned in a runaway preventive device 1 holds a switching means B under the state of ON. Consequently, power transistors 5, 7 on the lower side can be driven, and a motor 14 is driven and controlled. When a power switch 22 is turned ON under the state in which the current command signal S at a level where the motor 14 can be turned is input, the RS flip-flop circuit A in the runaway preventive circuit 1 holds the switching means B under the state of OFF. Accordingly, the power-transistors 5, 7 on the lower side cannot be driven.
