Title: Semiconductor component
Inventor: KOBAYASHI SHINICHI
IPC: H01L23/50
Filed: 1988-10-04
Abstract: A semiconductor component with an IC chip has a power supply lead (5) and a ground lead (6) which are both, with the exception of the outer ends of the leads, subdivided into at least two sections (5d, 5e and 6d, 6e) via one or more longitudinal slits (5c, 6c). The inner end of one section (5d or 6d) of the power supply lead (5) or of the ground lead (6) is respectively electrically connected only to output (final) stage transistors of a data in/output circuit in the IC chip (1), and the inner ends of the further sections (5e or 6e) of the power supply lead (5) or of the ground lead (6) are electrically connected to further circuits in the IC chip (1). The presence of the longitudinal slits (5c, 6c) in the leads reduces the effect on the remaining circuits of power supply noise produced in the output stage transistors during the laser operations. <IMAGE>

Filed: 1989-07-21
Abstract: A ski boot safety binding has a basic body (13) which is arranged on a swivel cam (15) so that it can swivel about a vertical axis (11) and which consists of two partial bodies which are prestressed resiliently towards one another in the direction of their longitudinal axis (14), can be pressed apart counter to the spring force along the longitudinal axis (14), and are supported from opposite sides on the swivel cam (15), which is fixed to the ski, in such a way that the partial bodies (13', 13") are increasingly resiliently pressed apart when the basic body (13) is rotated out of the normal position. Furthermore, pairs of retaining cams (16)/connecting members (17) are arranged on the partial bodies (13', 13") or the ski boot (18) so that safety release takes place both in forward and backward falls as well as in the case of excessive torsional loads. The ski boot (18) is retained on the basic body (13) against lateral displacements by fixed lateral stops (19, 20). At least some of the retaining cams (16) and/or connecting members (17) can be disengaged from the assigned connecting member (17) or retaining cam (16) respectively by lateral displacement counter to a spring force (61) which can be overcome relatively easily by means of a manual actuating lever (20). <IMAGE>

Patent DE-3935338-A1 (DE)
Title: Controls on extrusion-blow moulding - automatic system uses weight of tubular parison as datum value and adjusts extruded die gap as required to keep prod. within tolerances
Inventor: MORTON-FINGER JUERGEN DIPL ING
IPC: B29C48/92
Filed: 1989-10-24
Abstract: Control on extrusion-blow moulding machines is provided w.r.t. wt. measurements. In the process the cycle time and the wt. produced are measured, from which the wt. of the parison is obtd.; this wt. is compared with a target value and is adjusted by changing the target value of the wall thickness; the corresp. changed cycle time is fed back to the target time by modifying the speed of the extruder. ADVANTAGE - When the parison has the required profile its target wt. is set by the extruder die gap; the cycle time measured is that between closing the mould of one cycle and the same pt. during the next cycle, and this is triggered by a photoelectric cell. The speed of extruding the tubular parison should be that which ensures that the blow mould only waits briefly before receiving the tubing. The feed hopper of the extruder has a balance to weigh the supply, and a second hopper above the first has a control damper which remains open until the max. wt. of filling is reached. The max. and min. wt. values are the set target wts. The overall system produces precise measurement of the throughput.

Title: Pressure cycling gas adsorption system has selective throttles - in individual prod. gas outlets to common tank-supply conduit
Inventor: GERDTS UWE DR
IPC: B01D53/04
Filed: 1989-11-04
Abstract: Multi-component gas for purificn or rectification by treatment with adsorption columns filled with molecular sieve material, and each undergoing a cycle of adsorption and regeneration stages, is delivered from the column outlets by valved prod gas lines coupled to a gas-tank.  These lines leading to a common gas-tank feeder conduit each hold a throttle whose resistance to gas flow towards the feeder conduit is less than for the opposite flow direction. To provide this difference, the control throttle consists of a non-return valve with a first calibrated throttle operative in parallel with a second flushing aperture providing greater flow resistance. The throttles may involve resilient elements with circular or slotted apertures widening more in one direction that in the opposite (flashing) direction). ADVANTAGE - Continuous operation is combined with avoidance of prod-gas-loss due to excessive flashing gas pressence during regeneration.
