Title: Wire bonding and capillary chip
Inventor: TSUMURA KIYOAKI
IPC: H01L21/60
Filed: 1988-02-08
Abstract: PURPOSE:To form a uniform alloy layer over the whole junction part and perform highly reliable bonding by positioning the metallic ball of the end of a wire on a body to be bonded and perform plastic deformation by applying a load whose direction varies smoothly, continuously and further, joining the metallic ball with the body by applying ultrasonic oscillations to the metallic ball. CONSTITUTION:A copper wire 2 is inserted and pierced in a through hole 22 of a capillary chip 1 and the copper ball 4 having a diameter which has 1.5-2.5 times the diameter D2 of the copper wire 2 is formed by heating the end of the wire 2. Then, the ball 4 is positioned on an aluminum electrode 8 by lowering the capillary chip 1 and the copper ball 4 is deformed plastically by making the chip 1 go down further. In such a case, the chamfered parts 13 of the capillary chip 1 have protruding surfaces which curves smoothly, continuously with curvature R and allows loads 19 to vary continuously, smoothly. Thus, a semiconductor element 7 is heated up to a temperature 300-400 deg.C and ultrasonic oscillations are applied to the capillary chip 1 and then, both metallic elements of the copper wire 2 and the aluminum electrode 8 are secured by mutual diffusion.

Title: Data effectiveness or ineffectiveness discriminator and data processor
Inventor: KAJIYAMA KOUICHI
IPC: G06F3/05
Filed: 1979-03-08
Abstract: PURPOSE: To discriminate the effectiveness or ineffectiveness of data simultaneously with its processing, by comparing an actual data sampling interval with a previously set ideal sampling interval.  
     CONSTITUTION: A Doppler flow meter 1 acts to measure the flowing velocity of air by utilizing the Doppler effect. A Doppler signal is applied from the flow meter 1 to a signal processor 2 to determine the flowing velocity of air on the basis of the frequency of the Doppler signal. The output signal of the signal processor 2 is stored in a wave form memory 3. When the signal processor 2 generates a pulse, a counter 8 in an effectiveness or in-effectiveness discriminator 4 loads a pulse interval allowable value from a reference time setting unit 5 and counts down pulses from an oscillator 6. When the counted value becomes zero, the counter 8 produces a borrow signal and supplies it to an up-counter 10. A signal showing a measurement section is applied as a reset signal to the counter 10. A comparator 12 compares a counted value k 1  within the measurement section with an allowable value k 0  set by an allowably value setting unit 11. When the counted value k 1  exceeds the allowable value k 0 , sent data are regarded as improper.

Title: Gain memory cell circuit
Inventor: HOUGHTON RUSSELL J
IPC: G11C11/402
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent read-out disturbance from an unselected cell by reading out a written word value stored on a storage node by means of a read transistor via a diode between bit lines. SOLUTION: When a write transistor Tw0 in a gain cell 20 is operated by a write-in word line WLW0, a value of a write-in bit line BLW0 is stored on the storage node SN0. When a read-out word line WLR0 is enabled to work, the read transistor Tr0 to be connected with the storage node SN0 in this case is connected via the diode D0 to a read-out bit line BLR0, so as to read out the stored value. The diode D0 is capable of preventing conductivity in the reverse direction of the read transistor Tr0, thus preventing disturbance from another cell, and also decreasing capacitance of the bit line. The same is the case with the other memory cells.

Title: Improvement of residual stress of steel plate or the like
Inventor: YOSHIDA KAZUO
IPC: C21D1/00
Filed: 1985-02-14
Abstract: PURPOSE:To eliminate the surface tensile stress of a metallic material and to generate residual compressive stress therein by maintaining part of the surface of the metallic material in a cooled state by chillers then heating the circumference thereof. CONSTITUTION:The chillers 3 are brought into tight contact with the surface 2 of part of the metallic material 1 to be treated such as austenitic stainless steel to put the surface into the cooled state. The circumference in said part is then heated like arrows by a method such as heater, burner or induction heating. A 200-450 deg.C temp. difference is generated between the surface 2 in contact with the chillers and the inside layer part 4 by such cooling and heating. The compressive stress is generated in the inside layer part 4 where the temp. is high and the tensile stress is generated in the surface part 2 where the temp. is low by such temp. difference. The stress above the yield point is thus generated in the inside layer part 4. The heating is suspended and the material is naturally cooled, by which the residual compressive stress is generated in the surface part 2 and the generation of the corrosion cracking occurring in the tensile stress is prevented.
