IPC: F03B15/06
Filed: 1981-05-19
Abstract: PURPOSE:To prevent occurrence of shocks in operating a guide vane of a water turbine, by providing a guide-vane opening setting and adjusting section designed to make its output equal to the output of a control operating and amplifying section and a control setting and adjusting section designed to make the inputs to a guide vane control operating and adjusting section and the control operating and amplifying section zero. CONSTITUTION:A control setting and adjusting section 13 controls the set value of a water turbine speed setting section 2 or a water turbine output setting section 3 to make its input zero by utilizing the output of an adder 5 as an adjustment input, through driving of its setting pulse motor PM or internal adjustment of the adder 5. A guide-vane opening adjusting section 14 compares the output of a control operating amplifier 6 with a setting output of a guide-vane opening setting section 8 and drives the pulse motor PM for the section 8, such that the above two outputs are made equal to each other. Further, a guide-vane control operating and adjusting section 15 compares the output of the control operating and amplifying section 6 with the output of the guide-vane opening setting section 8 and effects internal adjustment of the control operating amplifier 6, such that the above two outputs are made equal to each other.

Title: Method and device for measuring hot scarfed quantity
Inventor: MORI TAKESHI
IPC: B23K7/06
Filed: 1992-02-26
Abstract: PURPOSE:To provide the means capable of accurately measuring the hot scarfed quantity. CONSTITUTION:Sectional profile measuring devices having plural laser distance finders are provided at the front and rear sides of a hot-scarfing machine 16. The laser distance finders are two-dimensional finders capable of measuring width at multiple points. The hot-scarfed quantity profile of a material to be hot-scarfed is found by calculation from the difference between the sectional profile before hot-scarfing and the sectional profile after hot-scarfing measured by the two-dimensional distance finders 12-1. Since multiple points are simultaneously measured by the two-dimensional distance finders, the sectional profile of moving material to be hot-scarfed is instantaneously and accurately measured. The hotscarfing quantity of the hot-scarfing machine is accurately controlled and the quality of the material to be hot-scarfed and the yield of hot-scarfing are improved.

Abstract: PURPOSE:To prevent the damage of Al wiring, and to improve the reliability and yield of the device by etching a barrier metal as a foundation under the state in which a noble metal thin-film of specific thickness or less is left on a barrier metal layer. CONSTITUTION:An Al electrode pad 2 on a semiconductor substrate 1 is coated with a protective film 3, and a Ti layer 4 and an Au film 9 of not more than 1,000Angstrom  thickness are evaporated onto the film 3 and the pad 2. A resist mask 6 is executed, the surface is plated with Au, and a bump electrode 8 is formed. When the mask 6 is removed and the surface of the substrate is exposed in an H2O2 group liquid, an etching liquid intrudes through defects such as the pin holes of the thin-film 9, and etches the foundation barrier metal 4, but Al is hardly etched. Accordingly, the Au thin-film 9 floats from the surface of the substrate in sections except a pad section. The thin-film 9 under an unstable state is removed easily through ultrasonic washing under the state. According to the constitution, an unnecessary Au thin-film is removed easily, Al wiring is not damaged by the severe etching liquid, and the reliability and yield of the device can be improved.

Title: Testing method and testing circuit of logic circuit
Inventor: NISHIDA KOJI
IPC: G01R31/28
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To enable the detection of short failures with reliability even when the voltage at a terminal becomes an intermediate voltage in the case of the short failure of a terminal in a testing circuit using a boundary scan cell. SOLUTION: When the voltage level of an outer terminal 7 is inputted to a capture register reg 2 via a comparator 6, the voltage level is not judged by the threshold level of the capture register reg 2. Instead, it is judged by the reference voltage Vref of the input end (-) of the comparator 6, and an intermediate voltage level which is uncertain to become either an H or L level is determined. Short failures can be thus detected with reliability.

Inventor: RUIJI RIBOORA
IPC: C23F13/00
Filed: 1993-03-11
Abstract: PURPOSE: To monitor the state and locate a protective coating by applying sine wave exciting currents of different frequency to a pipe line and determining presence of separated coating based on a corresponding voltage response. CONSTITUTION: Sine wave exciting currents of different frequency are applied from a signal generator 10 in a measuring unit 9 through a protrusion to a pipe line 1. A meter 13 detects a voltage response induced by the exciting current. A decision is made whether a defect 3 or a separation 5 is present in the protective coating 2 of the pipe line 1 based on the response of different amplitude to the sine wave of different frequency. In case of a defect 3, a significant variation can be recognized in the amplitude of voltage response when the frequency is varied in the range of 10-1Hz, for example. In case of a separation 5 due to corrosion, substantially invariant amplitude of voltage response is recognized.  More specifically, application of sine wave of different frequency causes to spread the voltage response for the defect 3 and produces a substantially matched response for the separation 5.

Abstract: PURPOSE:To change the traveling route of an unmanned carrier by only changing the content of a destination memory by eliminating the need for any guiding signal line to be laid on a floor. CONSTITUTION:Pictures photographed with a camera 1 are stored in a picture memory 3 after the pictures are binarized by means of a binarization processing section 2 and a pulse generating section 4 takes the difference between the pictures and generates a pulse from a hole formed into the floor. An address generating section 5 generates an address to a destination memory 6 storing the pulse number distance to the next destination and the memory 6 imparts the content of the address to a subtracting section 8. A current position storing section 7 imparts the current position to the section 8 and the section 8 finds the difference between the next destination and current position and imparts the difference to a target counter 9. The counter 9 subtracts the pulse number to the destination by using a pulse from the section 4, finds the moving pulse number moving amounts of the left and right tires of this unmanned carrier, and outputs the moving amounts. The moving amounts are transmitted to drivers 10a and 10b by which the moving amounts are converted into the rotations of the tires and motors 11a and 11b rotate the tires 12a and 12b to move the carrier to the destination.
