Inventor: ITO TAKASHI
IPC: H03K19/003
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction of an input circuit caused by driving an output circuit with a large current without increasing a chip area and without a considerable revision of a circuit layout design. SOLUTION: A series connection consisting of a capacitor 20 and a charging circuit 22 comprising transistors(TRs) QP5, QP6 is connected between power lines 6, 7 and a discharge circuit 23 consisting of TRs QN5, QN6 is connected across the capacitor 20. When the voltage of the power line 6 rapidly rises due to ringing the TR QP5 is turned on and the charges causing an overshoot of the power line 6 are absorbed by the capacitor 20. Thus, when a terminal voltage of the capacitor 20 rapidly rises, the TR QN5 is turned on after a delay time to discharge the capacitor 20.

IPC: F02F5/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To surely fit a C-shaped piston ring into a ring groove by fitting the vicinity of the notch of the C-shaped piston ring to the ring groove preferentially to the other part. SOLUTION: When push-down arms 73, 74 are lowered, contact protruding parts 77a, 77a push down the vicinity parts 4a, 4a of the notch N of an expander 4 to fit them into the ring groove of a piston 1. Since the vicinity parts 4a, 4a are regulated in axial movement by the ring groove, therefore, the end parts of the notch N never overlap. Since the vicinity parts 4a, 4a are fitted to the ring groove, they are never lowered more. Therefore, when the push-down arms 73, 74 are further lowered, the other part of the expander 4 is also fitted to the ring groove.

Title: Mos type semiconductor device equipped with current sensing terminal
Inventor: FUJIHIRA TATSUHIKO
IPC: H01L29/78
Filed: 1990-03-20
Abstract: PURPOSE:To obtain current sensing terminals free of sensing errors by depositing an insulating film thicker than a gate insulating film immediately under that one of gate electrodes which extends over adjacent main unit elements and sensing unit elements. CONSTITUTION:An insulating film 16 which extends over P wells 4, 4 of a sensing unit element QSE and a main unit element QO adjacent to this consists of the gate insulating films 16a, 16b of the same thickness as that of the gate insulating film 6 of the main unit element QO and an insulating film 16b thicker than those films. The thick insulating film 16b spreads over an n<-> epitaxial layer 3 sandwiched by the P wells 4, 4. A gate electrode 7' overlays the insulating film 16 and is coated with an interlayer insulating film 10'. As a result, the thicker the insulating film 16b is formed, the larger parasitic resistance RP becomes so that most of sensed current flowing through the sensing element QSE flows through a sensing resistor RSE; therefore, sensed voltage gets proportional to the ratio of cell count. This structure can provide MOS type semiconductor devices equipped with current sensing elements of less sensing errors.
