Title: Charge coupled semiconductor device with insulating layer capacitors - has several contacts on substrate surface with adjacent majority carrier depletion zones
Inventor: KNAUER KARL DIPL ING
IPC: G11C19/18
Filed: 1976-11-30
Abstract: The capacitors of the charge coupled semiconductor device are operated by drifting pulse trains with mutually phase shifted components. The pulse application generates majority carrier depletion zones on the substrate surface, with a presettable direction of drift. Several contact (13, 14) are deposited on the substrate surface and next to each contact are formed zones (131, 141) on the surface for generating a changeable majority carrier depletion zones. The depletion zone surrounds and separates the contact from the rest of the substrate. Thus application of voltage below breakdown voltage does not cause any current flow between substrate and contact. Minority charge carriers, applied to the depletion zone, can change it in such manner as to provide a current path between substrate and contact, dependent in cross section on the minority charge carriers quantity. The original condition is reset by removal of the minority charge carriers.

Title: High performance high speed impact forming machine - has working and auxiliary pistons for controlling restoring and working movements
Inventor: KNAEBEL HORST ING GRAD
IPC: B30B1/32
Filed: 1977-07-23
Abstract: The impact load produced within a few milliseconds or fractions of millisecond is generated by gas pressure acting on a piston in a cylinder. The piston is returned by hydraulic pressure. The arrangement has high production rate and its efficiency is high. The workpiece is relieved of pressure in controlled manner. This arrangement can be adapted to a wide range of production processes, e.g. floor pressing, forging, embossing, upsetting, stamping etc. The opening stroke of a first controlling auxiliary piston (27) cuts off pressurised fluid flow. This ensures coupling to the working piston (1). A second auxiliary piston (28) is provided so that between these two auxiliary pistons (27, 28) acts restoring pressure pushing in the pistons away from each other. The first auxiliary piston is pushed to close a valve seat (34) at the end of each working movement.
