Inventor: BARRE CLAUDE DIPL-ING
IPC: H03K19/00
Filed: 1990-12-18
Abstract: A CMOS switching stage (STV) having a first and a second power supply path for connection to in each case one supply voltage potential exhibits a voltage reducing member (SB) in at least one of the power supply paths. This voltage-reducing member (SB) results in a largely current-intensity-independent voltage difference. The transistors of this CMOS switching stage (STV) can be constructed to be smaller in integrated circuits since the drain-source voltage of the transistors is reduced. In circuits with current switch/switching stages, the CMOS switching stage (STV) constructed in accordance with the invention offers particular advantages because the expenditure for signal level converters for converting current switch output signal levels to CMOS input signal levels is considerably reduced due to the reduced output signal level excursion and the correspondingly adapted switching threshold in the CMOS switching stage (STV). <IMAGE>

Inventor: BETON GORDON
IPC: F16H48/42
Filed: 1990-11-02
Abstract: A reduced bearing life has been noted of the pinion support bearing particularly in the differentials of trucks which is caused by: 1) movements of the bearing innerring; 2) breakage of bearing flange; 3) bearing race-way distortion due to undercut support. These undercuts are formed during the gear cutting process. 
     The solution of avoiding these defects has been found in the application of a cylindrical roller bearing (26) which innerring (16′) is cup-shaped. The end-cup (16˝) of this innerring (16′) is used to (positive) locate the inner­ring, i.e. to prevent movement of this ring (16′) and/or flange breakage. The end-cap (16˝) further provides stiffness to minimise race-way distortion due to improper mounting or loads in case the innerring support (13) is undercut by the gear-cutting process.

IPC: C23C16/448
Filed: 1990-04-09
Abstract: Many devices, such as those based on III-V semiconductor materials, are produced utilizing gases such as arsine that require careful handling of compressed gas cylinders. This care has engendered a search for alternate approaches. It has been found that the use of electrochemically generated gases such as arsine yields an efficient, pure source of such gases without necessitating the storage of large gas quantities. Thus, a device fabrication procedure including in situ electrochemical generation of gases such as arsine is particularly useful.

Abstract: A master cylinder, particularly of the type in which the piston (10) is withdrawn from the bore (14), at least to the extent of providing a recuperation flowpath past a sealing ring (16) on the piston. The sealing ring (16) is axially and also preferably radially, floating between a bearing ring (30) (for maintaining piston alignment) and a shoulder (22) on the piston, the sealing ring being biased to urge a back face (20) (with respect to the forward piston stroke) into contact with a sealing surface of the piston. In response to such bias and also preferably an initial surge of pressure communicated to the radial clearance between the sealing ring and the piston, as the piston enters the bore, the sealing ring may be radially expansible to assist initial interference of the sealing ring with the cylinder.
