Abstract: PROBLEM TO BE SOLVED: To reduce the time and cost of adjustment prior to measurement work by correcting the outputs of an eddy current type displacement sensor in respective correction positions by theoretical values and linearizing the relations between the outputs of this eddy current type displacement sensor and measurement distances. SOLUTION: A controller makes zero setting of the output of the eddy current type displacement sensor 22 by bringing the eddy current type displacement sensor 22 into contact with the outer peripheral surface of a rubbing roller 21 and moves the eddy current type displacement sensor 22 to the prescribed measurement position with respect to the rubbing roller 21. The controller makes span setting by making the output of the eddy current type displacement sensor 22 in this position and the theoretical value correspondent to each other. The plural correction positions are determined in accordance with the range of the eccentric quantity measured on the basis of the measurement position of the eddy current type displacement sensor 22 and the number of the correction positions.  The theoretical values of the outputs of the eddy current type displacement sensor 22 in the respective correction positions are determined and the eddy current type displacement sensor 22 is moved to the respective correction positions.

Title: Yc separator circuit
Inventor: YAMADA HIROSHI
IPC: H04N9/78
Filed: 1986-11-04
Abstract: PURPOSE:To exploit only a signal with an excellent characteristic for a CCD, to make an output characteristic satisfactory and to obtain an inexpensive CCD by limiting a signal passing through the CCD to a chrominance component frequency band and converting the signal into a low frequency. CONSTITUTION:A band-pass filter 8 converts a composite video signal coming in a terminal 1 into a signal with a frequency (fSC+ or -DELTAf) included in chrominance components, and a frequency converter 10 frequency-converts the signal into the low frequency to attain a signal of frequency (fSC'+DELTAf). The CCD 13 delays the signal by 1H. Since only the signal of the low frequency passes through the CCD 13, the excellent characteristic for the CCD can be used. A frequency converter 12 frequency-converts a signal taken out of the CCD 13 into a high frequency to return it to its original frequency. A low-pass filter 3 removes the unnecessary high frequency component of the signal. A subtractor 4 subtracts an output signal from the low-pass filter 3 from the signal that is outputted from the low-pass filter 8 and lies in the chrominance component frequency, and takes out the subtracted signal as a component C from a terminal 5. A subtractor 6 subtracts an output from the subtractor 4 from the composite video signal coming in the terminal 1, and takes out it as a component Y.

Title: Bump forming method
IPC: C25D5/02
Filed: 1991-09-12
Abstract: PURPOSE:To eliminate a phenomenon that a bump peels, by heating a wafer after the bump is formed, or by evaporating residual etching solution in the lower part of a bump by putting the wafer in a vacuum vessel at 10<-3>Torr or lower for a specified period. CONSTITUTION:Patterned photosensitive resist 9 is used as a mask, and barrier metal 6 is etched by using etching solution composed of NH4OH of 30vol%, H2O2 of 30vol%, EDTA of 25g/l, and H2O of 40vol%. Thereby electric short of each bump 8 is cut off. The photosensitive resist covering the bump 8 is peeled. A wafer 1 is put in a vacuum vessel, which is vacuumized at 5X10<-6>Torr for one hour. Thereby residual etching solution at the lower part of the bump 8 is evaporated and eliminated. Hence it can be avoided that the barrier metal just under the bump is etched and the bump peels as the result of deterioration with age after element packaging.

Title: Touch sensor
Inventor: NAGASAWA KIYOSHI
IPC: G01L1/18
Filed: 1985-11-22
Abstract: PURPOSE:To enable highly accurate detection of a pressure state, by arranging a semiconductor pressure sensitive element and a pressure-receiving body junctioned on the element. CONSTITUTION:A semiconductor pressure-sensitive element 1 has a diaphragm section 5 as a pressure detector section and mounted to a chip carrier 7. A pressure receiving body 3 has a cylindrical pressure transmitting section 11 with one side thereof bonded to the pressure receiving section 13 and the other side thereof to the diaphragm section 5. A support section 15 enters a through hole 9 in the perimeter of the transmitting section 11 while bonded to a carrier 7. A rigid plate 17 is joined to the pressure receiving section 13 and a silicon rubber sheet 19 is adhered to the plate as contact surface with an object. In operation, a pressure applied to the pressure receiving section 13 through the plate 17 acts on the diaphragm section 5 through the transmitting section 11 to distort it. The distortion is outputted 23 as a pressure detection signal by a strain resistance of a piezo-electric resistance effect. Absence of mechanical sliding section at the transmitting section 11 ensure a stable pressure transmitting performance with excellent durability, thereby enabling highly accurate pressure detection.

Title: Method and apparatus for hydraulic test of steel pipe
Inventor: KOBAYASHI KUNIHIKO
IPC: G01M3/28
Filed: 1984-12-13
Abstract: PURPOSE:To certainly detect the leakage of water from an object to be tested consisting of a steel pipe and a screw joint, by delaying a boosting speed immediately before reaching testing pressure. CONSTITUTION:A highly precise relief valve is used as the relief valve 13 of a pressure hydraulic pump. Because the relief valve permits leakage little by little even under set pressure or less from a structural aspect, a flow amount is reduced from pressure corresponding to about 90% of testing pressure and a boosting speed becomes slow but, when testing pressure is achieved, a stop valve 11 is closed by the signal from a pressure sensor 5 and pressure is held. Within this pressure range, the boosting speed is made extremely long as compared with a usual case. Because a packing deforms in an equilibrium state, there is no deformation after the pressure was held and, so far as no leakage is generated in a joint, constant pressure is indicated after the testing pressure was achieved. Therefore, it is possible to perform clear discrimination from the lowering in pressure due to leakage from an object to be tested.
