Title: Electrophotographic photoreceptor
Inventor: KASHIMURA NOBORU
IPC: G03G5/147
Filed: 1991-02-22
Abstract: PURPOSE:To form a high hardness surface and to ensure superior scuffing and wear resistances and high durability by using a polymer of a specified monomer as the material of a surface layer positioned at the uppermost surface of a photoreceptor. CONSTITUTION:In an electrophotographic photoreceptor with an electric conductive substrate and a photosensitive layer applied on the substrate, a surface layer positioned at the uppermost surface of the photoreceptor is made of a polymer of a monomer represented by the formula, wherein R is R'-CR''=CH2, R' is an alkyl chain, O, CO, NH or S and R'' is H, CH2 or phenyl. Since the monomer polymerizes by radical polymn. but it is a monomer having remarkably high functional group density and the rate of reaction is very high, the polymn. reaction of the monomer proceeds even under mild conditions and hardly damages a photoconductive material excellent in compatibility and dispersibility. Because of the remarkably high functional group density, the resulting polymer has very high hardness and a superior high durability photoreceptor is obtd.

Title: Key device for moving cursor
Inventor: MIYAGAWA AKIRA
IPC: G06F3/033
Filed: 1983-03-25
Abstract: PURPOSE:To make the continuous movement of the cursor possible by operating a single key top, then selecting the moving direction of a cursor through sliding operation of a key top in the horizontal direction and depressing the key top in the vertical direction. CONSTITUTION:When a key top 5 is slid in the direction A by putting a finger in the vicinity of a point B at the center of the key top 5, force is applied to flat-spring contacts 8X and 8Y and both the contacts are contacted with each other. A CPU13 reads the contacted information and moves a cursor on a display section 2 by one scale division in both vertically upward direction and horizontally leftward direction. When force is added toward vertically downward direction to the finger put in the vicinity of the center of the key top 5 under this condition, a flat-spring contact 11 is contacted. The CPU13 reads this contacted information and works so that the cursor on the display section 2 can make a continuous movement. When the finger is removed from the key top 5 under this condition, each flat-spring contact is returned to the original position and each contact is opened and, as a result, the movement of the cursor is ended.

Title: Printing head gap regulating mechanism
Inventor: SAEKI TOMOYA
IPC: B41J2/06
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To maintain the intensity of a discharge electric field in a stable state even when the thickness of a recording medium to be used changes and thereby, keep a recorded image steady qualitatively, in an electrostatic ink jet recording device. SOLUTION: This printing head gap regulating mechanism is of such an operating function that the electrostatic capacities of a discharge electrode 4 and an opposed electrode 5 are detected by an electrostatic capacity detecting circuit 14 under such a state that a recording medium 6 is introduced onto the opposed electrode 5 and the intensity of an electric field in the discharge electrode 4 is calculated by a gap regulating control part 15 based on the detected electrostatic capacity to control a motor drive circuit 16 so that the intensity of an electric field becomes a previously set value. Thus it is possible to regulate the gap between the discharge electrode 4 and the opposed electrode 5 by rotating a leadscrew 10 with a motor 12.

Title: Power source device for electric discharge machining
Inventor: KITAGAWA KOJI
IPC: B23H1/02
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To more accurately detect a leakage current by arranging a detecting- judging circuit to detect the leakage current by using a differential value of discharge voltage calculated in a period when a clearance between a discharge electrode and a work is charged with an output current from a contact current circuit. SOLUTION: When a leakage current is generated, a clearance can be equivalently expressed by a circuit connected in parallel by using equivalent capacity and equivalent resistance as a circuit constant. In this case, when an impression of voltage is started at the time T0, an equivalant circuit becomes a primary delay circuit in time up to T2 from the time T0, and shows a tendency having a time constant. Therefore, when voltage Va by dividing discharge voltage is differentiated by a differentiator 2, it does not become a constant value as shown in Vb. Therefore, when reference transmissions Vrefa and Vrefb of two stages are compared with each other by a window comparator 3, a signal of Vc is obtained.

Title: Gate circuit
Inventor: HIRAKI MITSURU
IPC: H03K19/0175
Filed: 1990-03-02
Abstract: PURPOSE:To attain rapid operation even when the voltage of a power supply is reduced by supplying current from the power supply to the base of a bipolar transistor(TR) for executing pull-down operation through a p-channel MOSFET to drive the bipolar TR. CONSTITUTION:The source terminals of the p-channel MOSFETs 101, 102 are connected to power supply voltage Vcc and the bipolar TR 107 is driven by the drain terminals of the MOSFETs 101, 102. At the time of pull-down operation, the source of the FET 101 or 102 is connected to the voltage Vcc, a low level '0' is inputted to the gate, the voltage between the drain and source is dropped only by the voltage between the base and emitter of the TR 107, but since no loss is generated in the voltage between the gate and source, the TR 107 can be driven with high power. Thereby, even when the voltage of the power supply is reduced, the driving power of the TR 107 is not sharply reduced and the TR 107 can rapidly be driven.

Abstract: PURPOSE:To amplify an etching end signal, and easily and accurately monitor the end of etching by enlarging the etching area by removing the resist at the wafer area which does not become a product. CONSTITUTION:A hard mask A is produced by vacuum depositing a chrome film 2 on a glass substrate 1 in such a way that the periphery of mask pattern 3 which is smaller than wafer 4 is perfectly covered by said chrome, and it is then stacked, through positioning, on the wafer 4 on which negative photo resist 5 is coated and then exposing is carried out. Since the corresponding part 5A on the wafer 4 at the external side of pattern 3 is not exposed, such part is removed by developing process. In case of executing the etching SiO2 using CHF2 as the etching gas, since the etching area is expanded, amount of CO generated increases and light emitting intensity of plasma changes largely at the end of etching.
