Patent DE-2203204-B2 (DE)
Title: Load cell using torsional vibrating element - has flat cord whose resonant frequency varies with loading and includes coil in field of permanent magnet
IPC: G01G3/16
Filed: 1972-01-24
Abstract: The load cell comprises a flat rectangular cord (16) with its upper end fixed to a support (3). Its lower free end is terminated in a block (4) to which is attached a hanger (7) by means of a strip and smaller block (5, 6) which pre-tension the cord. A coil (10) is attached to the cord and arranged symmetrically about its longitudinal axis. The coil is placed between the poles of a permanent magnet (11, 12) which is unaffected by the movement of the torsion vibrator. The torsional stiffness of the vibrator depends on the force to be measured (G). The weight attached to the free end alters the resonant frequency. Excitation can be achieved by the use of more than one coil. The flat tape may also be replaced by two parallel wires.

CONSTITUTION:In a semiconductor device where a chip is united with a carrier 2 via a heat sink 1, the heat sink 1 and the carrier 2 are bonded by a thermal pressure bonding operation using gold as a bonding material. For example, a three-layer coating composed of a titanium layer 3 (600Angstrom  thick), a platinum layer 4 (800Angstrom  thick) and a gold layer 6 (1mum thick) is formed on the surface of a diamond heat sink 10.55mm square by an evaporation method under conditions of a pressure of 5X10<-6> Torr, at a substrate temperature of 200 deg.C and at a speed of 10Angstrom /sec. A two-layer coating composed of a nickel layer 5 (3mum) and a gold layer 7 (3mum) is formed on the surface of oxygen-free copper of a carrier 2 by an electrolytic plating operation. After that, a thin gold piece 8 with a thickness of 50mum is inserted between the heat sink 1 and the carrier 2; both are heated to 270 deg.C; after that, they are pressurized by a force of 1000gf and a thermal pressure-bonding operation is executed.

Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of an overall device, when the power outputted from a prime mover is torque-converted and outputted to a drive shaft. SOLUTION: This power output device 20 converts the power outputted from an engine 50 into a desired power by a clutch motor 30 and an assist motor 40 and outputs to a drive shaft 22. When required torque outputted to the driving shaft 22 is needed, a control CPU 90 of a controller 80 calculates the total loss of respective operating conditions of the engine 50, the clutch motor 30 and the assist motor 40 which can output the required torque, determines the operating conditions such that the total loss is minimum and controls the operation of the engine 50, the clutch motor 30, and the assist motor 40. It is thus possible to enhance the efficiency of the overall device.

Abstract: The invention relates to a heat exchanger comprising a heat exchanger grid having a multiplicity of oval tubes (3), and a baseplate attached to said grid by widening the tubes (3). The ratio of the diameters of the tubes (3) is 2.5 : 1 to 8 : 1 inside the heat exchanger grid, and 1.2 : 1 to 3 : 1 inside the perforations of the baseplate. A process for fixing such heat exchanger grids to a baseplate is also described. This process is characterised in that before being widened the tube ends are deformed from outside by applying pressure with the aid of a special pressure tool (15, 15a,b), with the result that their cross-sections are reduced parallel to the maximum diameter but increased, by contrast, parallel to the minimum diameter. <IMAGE>
