Patent JP-S5628874-A (JP)
Title: Thermal recording head
Inventor: ENDOU TAKAFUMI
IPC: B41J2/335
Filed: 1979-08-18
Abstract: PURPOSE:To enable printing at a low cost with high accuracy of light and shade, by using a high resistance region, which is produced by energizing between auxiliary electrodes opposed to each other across a resistance zone, to prevent a printing current from flowing to adjacent heating resistors. CONSTITUTION:A current of 30-50w/mm.<2> as to the unit area of the resistance zone 7 provided between the ends of opposed electrodes is caused to flow through the resistance zone to produce a high resistance region 8. An impulse voltage is then applied across auxiliary electrodes 6 to produce a high resistance barrier between the electrodes 6 and heating resistors 9 adjacent thereto. Impulse voltages are sequentially applied across opposed auxiliary electrodes 6 between lead electrodes 2 to produce high resistance barriers between the ends of the auxiliary electrodes on the resistance band 3 extending long on the top of an insulating board 1. The resistance band 7 is thus divided by the high resistance barriers to provide numerous heating resistors 9 insulated from one another. When a printing current of prescribed level is caused to flow through a prescribed heating resistor, for example, 93, the current is prevented from flowing to the adjacent heating resistors 92, 94. Therefore, the prescribed printing current flows through only the heating resistor 93.

Title: Pipe
Inventor: SEKI YOSHITAKA
IPC: F16L11/11
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To prevent accumulation of water or waste by forming a small diameter part and a large diameter part non-coaxially with each other, matching the outer circumferences of them mutually along one side face of a pipe, and extending the matching parts linearly in the parallel direction to the pipe axis. SOLUTION: In this pipe 4, small diameter parts 5 and large diameter parts 6 are alternately formed in the pipe axis direction and formed non-coaxially with each other, and in one side face part of the pipe 4, the outer circumferences of the small diameter part 5 and the large diameter part 6 are matched with each other, The matched part is linearly extended parallelly to the pipe axis. In this way, the pipe 4 can be freely bent because the small diameter parts 5 and the large diameter parts 6 are alternately formed in the pipe axis direction, so that flow resistance of water or the like inside the pipe 4 can be greatly lowered, and consequently, accumulation of liquid or waste in a lower side part 7 can be prevented almost completely.

Filed: 1985-05-17
Abstract: PURPOSE:To improve a gm value by reducing the thickness of the gate oxide film of a low withstand voltage MOS semiconductor element from that of an intermediate withstand voltage MOS semiconductor element when the intermediate and low withstand voltage MOS semiconductors are formed on the same substrate. CONSTITUTION:A channel-stopper region 2, a field oxide film 3 and an insulating film 11 are formed on a P-type semiconductor substrate 1. After the film 11 of the region to become a low withstand voltage MOS transistor is removed, gate oxide films 6, 4 are formed. As a result, the thickness of the film 4 is increased as compared with the film 6. Then, a gate polycrystalline silicon electrode 5 and an N-type low density drain (source) region 9 is formed. Subsequently, after the oxide film is selectively removed, a thin oxide film is formed, the drain (source) region 7 of each MOS transistor is formed. Thereafter, an interlayer insulating film 10 and an aluminum leading electrode 8 are formed.

Title: Semiconductor switching circuit
Inventor: INABE YASUNOBU
IPC: H03K17/72
Filed: 1981-07-08
Abstract: PURPOSE:To reduce the variation of extracting current even if operational power voltage is changed by constituting a driving circuit by a current extracting circuit for cutting off a thyristor of which output resistance is sufficiently increased. CONSTITUTION:A driving circuit with the sufficiently large output resistance of a current extracting circuit 20 is used for a titled circuit. Load resistors 4, 4a are connected to a cathode terminal K and an anode terminal A, respectively and negative and positive power source (voltage -VA, +VA) 5, 5a are connected to the cathode terminal K and the anode terminal A respectively. Consequently, when a thyristor 1 is connected, the potential of the cathode and gate terminals K, G is changed from +VA to -VA by the resistance values RA, RAa of the load resistors 4, 4a. Thus, even if the operational potential of the thyristor 1 is changed, the variation of current IG can be reduced because the output resistance value of the current extraction driving circuit 20 is large.

Abstract: PURPOSE:To use the titled flip-flop for a high speed digital circuit by activating the D-FF at both leading and trailing edges of a clock pulse so as to halve the speed of the clock in comparison with that of a conventional D-FF. CONSTITUTION:When a clock (CK) is at a low level, an input D at a terminal (0) of a selector circuit 1 is outputted and when the clock CK is at a high level, the preceding state is held. When the level of the CK is high, the input D at the terminal (1) of a selector circuit 2 is outputted and when the level of the CK is low, the preceding state is held. When the input D is at a low level and the Ck is at a low level, the output (a) of the selector circuit 1 goes to a low level and it is continued until the input D goes to high and the CK goes to a low level. When the CK is at a high level, the output (b) of the selector circuit 2 goes to a low level and when the CK is at a high level and the input D goes to a high level, the output goes immediately to a high level. Thus, the output Q goes to a low level while observing the change in the output (a) from the leading of the CK and goes to a high level while observing the change in an output (b) from the trailing of the CK.
