Title: Hydraulic directional control valve
Inventor: SCHUTTENBERG ECKARD
IPC: F16K11/07
Filed: 1982-07-17
Abstract: A hydraulic directional control valve (10) is proposed which has a longitudinal slide (13), at the piston section (17) of which a wide and flat annular relief groove (18) reduces the slide friction forces owing to radial applied forces on one side without significantly changing the flow characteristic. In the area of a bore section (16) lying between two chambers (14, 15), the piston section (17) has a single annular relief groove (18) of a few hundredths of a millimetre recess depth which is penetrated by a precision control notch (22). As a result of its large pressure-balancing surface (23), the flat annular groove (18) centres the longitudinal slide (13) in a hydraulically stable manner in the slide bore (2) and, during the plunging into a chamber (15), leads less to disturbing discontinuities in the profile of the flow characteristic (24), as predetermined by the geometry of the precision control notch (22). <IMAGE>

Title: Integrated CMOS circuit with increased resistance to the latch-up effect
Inventor: TANIGUCHI MASAHRU
IPC: H01L27/092
Filed: 1983-05-06
Abstract: A CMOS circuit with increased resistance to the latch-up effect comprises a buried layer (112) which has a relatively high impurity density and is situated underneath an MOS device. In a CMOS IC, an MOS is formed directly in a primary semiconductor layer, whereas the second CMOS is formed in a diffused island region (106) inside the primary layer. The buried layer (112) is situated underneath the first MOS and increases the base density of the parasitic bipolar transistors in the region of the first MOS. Since the buried layer (112) is not situated underneath the island region (106), the dielectric strength between the island region (106) and the semiconductor substrate (105) is not limited. <IMAGE>
Patent DE-3320612-A1 (DE)
Inventor: JENNY WERNER
IPC: B23B31/20
Filed: 1983-06-08
Abstract: The drill spindle of a deep well drilling machine has a sleeve-like extension with a conical internal surface which is complementary to conical external surfaces on an annulus of claws forming part of a clamping device which is inserted into the extension and has an axial passage for the shank of a rotary tool. A set of dished springs normally urges a ring against a conical end face of the clamping device whereby the latter urges its claws against the internal surface of the extension and the claws transmit torque from the spindle to the shank of the tool. If the transmission of torque is to be terminated, the piston of a fluid-operated motor is caused to shift the ring against the opposition of the dished springs whereby the claws relax the force with which they engage the shank and the latter can be extracted from the passage of the clamping device.

Patent DE-3330851-A1 (DE)
Inventor: SCHWABE ULRICH DR
IPC: H01L21/82
Filed: 1983-08-26
Abstract: A method for manufacturing VLSI complementary MOS field effect transistor circuits (CMOS circuits). By use of a suitable gate material, preferably a gate material comprised of silicides of high melting point metals, a threshold voltage of n-channel and p-channel CMOS-FETs having gate oxide thicknesses dGOX in a range of 10 to 30 nm is simultaneously symmetrically set by means of a single channel ion implantation. Given employment of tantalum silicide, the gate oxide thickness dGOX is set to 20 nm and the channel implantation is executed with a boron dosage of 3x1011 cm-2 and an energy of 25 keV. In addition to achieving a high low-level break down voltage for short channel lengths, this enables the elimination of a photolithographic mask. This represents an improvement with respect to yield and costs. The method serves for the manufacture of analog and digital CMOS circuits in VLSI technology.
