IPC: H01L23/538
Filed: 1990-10-31
Abstract: On an insulating layer (32) formed on a metal substrate (31), cascode-connected power switching elements (1-6) are provided and shield patterns (101-104) are formed. Control circuits (13-18) for the switching elements (1-6) are formed on insulating layers (105, 106) formed on the shield patterns (101-104) which are fixed to potentials responsive to potentials of output electrodes of the corresponding switching elements (1-6). The control circuits (13-18) and the corresponding shield patterns (101-104) are in capacity coupling. Thus, noise arises in the control circuits (13-18) with respect to the metal substrate (31) when noise is applied to current paths of the switching elements (1-6) with respect to the metal substrate (31). As a result, viewing from the output electrodes of the switching elements (1-6), the control circuits (13-18) have noise equivalent to nothing.

Inventor: PFEIFFER WOLFGANG DR ING
IPC: C02F1/463
Filed: 1991-07-26
Abstract: In processing and reuse of waste water, esp. contg. active washing cpds. and of rinsing water from cleaning of articles, esp. vehicles, the used wash water and the used rinsing water are fed together, as waste water, to a container, part of the waste water is filtered to recover (part of) the needed wash water, so that active washing cpds. in the waste water are reused, and part of the waste water is processed by flotation to recover (part of) the needed rinsing water. Fresh water pref. demineralised, is added to the rinsing water in at least one rinsing stage. The part of the waste water reused as wash water is filtered in a multi-layer filter, esp. with layers of differing granulation pref. a layer of coarse hydroanthracite and/or a layer of finer quartz sand. A pressure redn. flotation is used, and metal salts or a flocculating agent is added to the part of the waste water to be fed to the flotation. At least part of the flotation sludge is recycled to a pptn. stage. The part of the waste water to be fed to the flotation is (partly) exposed to a tension discharge. Waste water which is not to be reused may be processed by flotation. ADVANTAGE - The process is simplified, and the amt. of active washing cpds. to be added is reduced. Metal salts are not added and the water can be recycled for a longer time, reducing the amt. of fresh water needed and the amt. of waste water

Title: Automatic brake control with proximity sensor - provides programmed retardation and braking for fail=safe driving of motor vehicle in traffic
Inventor: KUNIMI TAKASHI
IPC: B60T7/22
Filed: 1992-06-04
Abstract: The brake control system has a proximity sensor (39) to measure the distance to an object, e.g. a leading vehicle. The control computes the relative speed between the vehicles and the likely impact time. The system operates the vehicle brakes if impact is predicted, the level of braking depending on the time estimated-gentle braking for longer times, and strong braking for shorter times. The computed impact time is compared with two reference levels. Above the first level the system either operates a warning to the driver and/or operates the brakes gently. Above the second level string braking is applied. The lower level is lifted once the driver applies the brakes. ADVANTAGE - Improved safety when driving in heavy traffic.
