Filed: 1984-11-07
Abstract: PURPOSE:To provide a high performance complemental MISFET without latch-up, by using a P type silicon in a P type semiconductor region, in which an N type MISFET is formed, using N type germanium in an N type semiconductor region, in which a P type MISFET is formed, and making the channel conductances of both parts approximately equal. CONSTITUTION:In an N type silicon semiconductor substrate 1, a P type silicon well 2, in which P type impurities are selectively diffused, is provided. An N- channel MOSFET is formed in the well. At a part of the surface of the substrate 1, an N type germanium semiconductor region 9, in which germanium is selectively grown epitaxially, is formed. In this region 9, a P-channel MOSFET is formed. In this semiconductor device, rising time of the output waveform becomes as quick as the speed of a falling time. Unbalance between both times is eliminated, and a high speed CMOS inverter circuit can be formed.

Title: Water tap fixing structure
Inventor: AZUMA TSUTOMU
IPC: E03C1/042
Filed: 1994-09-28
Abstract: PURPOSE: To make works for the body of a water tap simply and easily by inserting and rotating a coupling leg into a fixing seat ring, moving detent pawls to the position of a holding part, and generating a stop by the use of a reactive force of an elastic material. CONSTITUTION: When a coupling leg 2 is inserted in a fixing seat ring 3 furnished on the mounting surface, detent pawls 2c, 2d pass through a guide groove in the seat ring 3 and move toward the detention surface. If then the leg 2 is rotated, the pawls 2c, 2d run against the detention surface and rotate in sliding. At this time, the detention surface has an uneven surface profile, and there is a holding part which becomes concave oppositely to the inserting direction. Therefore, the detent pawls 2c, 2d move till the position of the holding part and is put in standstill by the elastic reaction force of a picking 6 installed between the body 1 of a water tap and the seat ring 3. Accordingly installation of the seat ring 3 and fitting of the body 1 of the water tap can be performed only by operation made from over the mounting surface.

IPC: E01C9/08
Filed: 1994-08-22
Abstract: PURPOSE: To obtain the title covering plate to which shock-absorbing legs are easily fastened and which has no fear of corrosion, by a method wherein each leg plate having holes is fastened to the bottom surface of the covering plate and shock-absorbing legs made of shock-absorbing material are fitted into the holes on the leg plates. CONSTITUTION: Leg plates 2, each of which consists of a belt-shaped steel plate and has holes 2a at regular intervals, are fastened to the bottom surface of both ends in the longitudinal direction of a covering plate 1, by welding or the like. After that, shock-absorbing legs 3 each are fastened to the leg plates 2 by fitting projections 3b on the shock-absorbing legs 3 into the holes 2a on the leg plates 2. In this way, since the shock-absorbing legs 3 are fastened to the covering plate 1 by fitting the projections 3b to the covering plate 1, the covering plate 1 can be easily set-up. Furthermore, since the leg plates 2 with the holes 2a are fastened to the covering plate 1, it is unnecessary to perforate the covering plate 1, and thus the covering plate 1 can be prevented from corroding owing to the permeation of rainwater or water.

Title: Voltage-current converting circuit
Inventor: AKUTAGAWA TOORU
IPC: G11B5/027
Filed: 1982-12-30
Abstract: PURPOSE:To suppress the generation of distortions by using the negative feedback to set an input point at zero impedance and therefore stabilizing the signal current with a resistance put between an input source and the input point. CONSTITUTION:An input source 20 is supplied to the base of an input transistor (TR)Q11 via a resistance RI. The collector output of the TRQ11 is negatively fed back to the base of the TRQ11 via the base and the emitter of the 2nd TRQ12. As a result, the input impedance is set at zero and an input current iIN is decided by the input voltage eIN and the resistance RI. The constant current sources 16 and 17 are connected to the emitter and the collector of the TRQ12 respectively, and these current values are set at the same level by TRs Q13- Q18. Therefore the current I4 delivered to a TRQ20 from the TRQ12 is equal to the current iIN.
