Title: Liquid crystal display device
Inventor: OKADA SHIGERU
IPC: G02F1/1343
Filed: 1987-09-30
Abstract: PURPOSE:To prevent a disconnection accident in a flexed part from being generated even when a circuit board fluctuates by forming an electrode connected to the electrode of a transparent substrate and flexed from an electrode forming plane, and providing the circuit board provided with the electrode at one end and extending in a direction opposite to the electrode forming plane. CONSTITUTION:The electrode 8 connected to the electrode 4 of the transparent substrate and flexed from the electrode forming plane 7 is formed at the outer edge of the transparent substrate 1 on one side. And the circuit board 11 provided with the electrode 8 to be connected to the electrode 4 formed at the outer edge of the transparent substrate 1 on one end and extending from the outer edge of the transparent substrate on one side to the direction opposite to the electrode forming plane 7 is provided. Since the circuit board is extended in a direction to be separated from the electrode forming plane, it is possible to receive an external force at the tip part of the electrode even when the circuit board fluctuates in an up-and-down direction, and since the electrode is formed in a stable state in a constant range from the tip part for the transparent substrate, it is possible to prevent the electrode being peeled from the transparent substrate. In such a way, the disconnection accident of the electrode can be prevented from being generated.

Filed: 1983-12-26
Abstract: PURPOSE:To improve yield rate remarkably by reducing the length of the last sheet cut by a sheet cutting shear in the required minimum. CONSTITUTION:At a point of time when a required number of sheets may be obtained, a start signal TS of a trailing end cutting shear 1 is given to an operation control unit 32 from the outside. Whereupon, the counting of strip feed length pulse signals PL input through a length measuring control device 30 from a measuring roll 20 is started with a timing signal SC of a sheet cutting shear 24 just after the start signal as the starting point. When the count number Q is in accord with a preset value P, a stop command signal ST for stopping the strip at the trailing end cutting shear 14 portion is output to a pinch roll 16, and when the strip is stopped, a trailing end cut command signal TC is given to the trailing end cutting shear 14. After that, the dwonstream strip is cut by the trailing end cutting shear 14 and sequentially cut by the sheet cutting shear 24.

Title: Power line carrier communication equipment
Inventor: NISHITANI HIROYUKI
IPC: H04B3/54
Filed: 1985-11-05
Abstract: PURPOSE:To attain normal power line carrier communication even when the line impedance is lowered by sending a transmission signal periodically to a power line, detecting the transmission level and controlling the transmission power so as to make the transmission level constant. CONSTITUTION:A detection section 26 is added between the power line 1 and a controller 28 and a negative feedback circuit (NFB) 27 is added in parallel with a transmission section 22. The controller 28 issues a command to send a shot pulse to the transmission section 22 once for 3min, for example. The transmission level of the power line 1 is detected by a detection section 26, its level is transmitted to the controller 28 and a negative feedback circuit 27 is activated so that the output of the transmission section 22 is made the same depending on the level to apply negative feedback. The level is kept for 3min, and when the line impedance is changed at the next detection, the quantity of the negative feedback is changed to send the transmission output being always at a constant level to the power line 1. Thus, the relation between the line impedance and the transmission output is constant regardless of the line impedance, the communication is stabilized and the reliability is improved.

Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a method which is valid at the time of complementarily dividing a pattern for solving the problem of the jointing line of the divided pattern, moreover without deteriorating transfer accuracy. SOLUTION: Fine linear width accuracy is required for a logic circuit pattern at A, B, C, and D parts in which the logic circuit pattern is formed, and not so much fine linear width precision is required in the other parts.

Title: Paper loading device
Inventor: YAMADA KENJI
IPC: B65H29/22
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent the backflow of loaded paper without complicating a discharge port and improve the sheet jogging property by providing, on an upper discharge tray, an end fence for jogging rear ends of sheets, which is raised and lowered synchronously with the sheet loading surface. SOLUTION: An inlet sensor SN1 and an inlet roller 4 are provided near the sheet delivering position J with a copying machine G as image forming device. The sheet taken by the inlet roller 4 is discharged from a discharge port E2 directly without binding treatment to a discharge tray 1 as upper discharge tray or a discharge tray 2 as lower discharge tray and large-quantity discharge tray. Since the discharge tray 1 integrally has an end fence 1a for jogging rear ends of sheets, the loaded paper can be prevented from flowing back to the discharge port E2 without complicating the structure of the discharge port E2. Since the loaded paper never make contact with the component of the discharge port, disturbance or contamination of the sheets can be prevented.

IPC: G11B5/31
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To suppress curving of the surface of a gap layer by making a prescribed relation between the difference of a height of the upper face of the gap layer in the center line position in the track width direction from a height of the upper face of the gap layer in a position apart from the center line by a prescribed distance in the track width direction and the gap length of the gap layer satisfied. SOLUTION: When the relation among the difference of the height A, the gap length H1 and a distance H2 between an upper and lower shield layers is expressed by the formula A=H1-H2, if the lower face Mb of a region M is overlapped by the lower face Rb of a magnetization inversion region R1, a corner part Ma1 of the upper face Ma of the region M is present on the upper face R1a of the magnetization inversion region R1. If the gap layer is curved, the relation is expressed by the formula A>H1-H2 and the corner part Ma1 of the upper face Ma of the region M is present outside the upper face R1a of the magnetization inversion region R1.  That is, if the relation is expressed by the formula A<=H1-H2, the gap layer has such a range of curvature that the region M is present inside the magnetization inversion region R1 on a recording track and a magnetic head for reproduction can surely clearly read the signal recorded on the magnetization inversion region R1.
