Title: Forming method of semiconductor element electrode
Inventor: CHIYODA KIYOSHI
IPC: H01L21/302
Filed: 1978-02-09
Abstract: PURPOSE: To form the semiconductor element electrode by deciding the etching termination point with use of the reflected light and then stopping the etching.  
     CONSTITUTION: The light is projected into bath 1 containing phosphoric acid group etching solution 2 from light source 3 through transparent window 12. The resist mask is formed on the Al film on electrode forming surface 51 of semiconductor element 5 supported by frame 4, and exposure part 52 reflects the light outside window 12. The reflected light is received at photo cell 6, and the output change of the reflected light is observed through monitor 7 containing the DC amplifier, the noise filter and the voltmeter each while the etching is progressing. The output voltage decreases after start of the etching and becomes constant when the Al film is etched away. At this momemt, the etching is stopped. With this method, the photoelectric conversion element is outside the bath, and thus the structure of the device can be simplified. And the etching termination point can be set up under the steady output signal owing to the steady state of the element surface through utilization of the reflected light.

Title: Device for controlling rectilinear running of construction vehicle
Inventor: HASEGAWA YOSHIMI
IPC: F15B11/05
Filed: 1991-01-10
Abstract: PURPOSE:To prevent the unprepared curved travel of a vehicle during its rectilinear running by driving a motor for right and left running through only one variable pump, and ensuring the rectilinear running of the vehicle when the openings of variable orifices are equalized. CONSTITUTION:When first and second control valves 3,5 are operated in the same direction, a signal control valve 30 is changed over to a position (b) on a lower side, and the second pilot chambers 11b, 12b of pressure compensating valves 11,12 are thereby connected to a tank 33. The pressure compensating valves are therefore kept at a fully opened state by pressure action on the side of pilot flow pathes 23, 24 to lose their pressure compensating functions. This state is similar to one where both running systems are arranged in parallel to a variable pump 1. Thus pressure in the both running systems is automatically kept at the same value for compensating rectilinear running.

In these coloring zone S and decoloring zone D, a coloring liquid and a decoloring liquid each are injected into and discharged from the support 1 in synchronization with the transfer of the support 1. Because of the injection and discharging, the coloring and decoloring liquids become fatigued. Therefore, the number of the objects being examined is computed by an judging device 7 and, based on the value computed, the degree of the fatigue of the colring and decoloring liquids is determined. According to the determination, both liquids are supplied to a coloring liquid tank and a decoloring liquid tank when the degree of fatigue has been confirmed.

Abstract: PURPOSE: To automatically lock a carriage arm to a housing position at the time of the electric power supply off from a disk driving device by disposing an actuator latch of a shape memory alloy adjacently to the rotating disk within a data memory device. CONSTITUTION: The shape memory alloy wire 73 is transformed to austenite when the shape memory alloy wire 73 is energized and heated through wires 69, 71. The shape memory alloy wire 73 is stronger than an elastic arm 55 and pulls the arm 55 in the direction parting from a pin 49. A pin 47 is made freely movable to the rear surface of the arm 55. When the head part 60 of the arm 55 arrives at a zero position, the pin 49 of the actuator arm 32 is captured. The arm 32 is held together with its transducer in the position where the disk is not loaded until the electric power supply to the motor is restored. The pressing arm 55 does not interfere with the pin 49 when the electric power is shut off. When the shape memory alloy wire 73 is actuated by supplying the electric power to the arm 55, the arm 55 is adequately retreated and the arm 32 is safely moved.

Abstract: PURPOSE:To remarkably reduce the number of composing elements by providing a masking means for inverting the value of an output signal for masking as soon as the value of the output signal from a toggle flip flop circuit is inverted even number times and for holding the value of the inverted output signal for masking. CONSTITUTION:In the toggle flip flop circuit 1, the output signal QT is initialized in one with a reset signal, the inverse of RS(row active) and the value of the output signal QT is inverted at the trailing edge of a signal to be detected C (the leading edge of the inverted signal, the inverse of C). A circuit (masking means) from the inverse of RS flip flop 3 to a NAND gate 7 masks the detection of C twice if a mode signal A is one. The output signal G1 detects the odd number fold signal to be detected C if the mode signal B is zero (if the mode signal A is zero, the first signal to be detected is detected and if the mode signal A is one, the third signal to be detected C is detected) and if the mode signal B is one, the even number fold signal to be detected C is detected.

Abstract: PURPOSE:To obtain a frequency relation between an input and an output signal of a voltage controlled oscillator by constituting a phase locked loop of the voltage controlled oscillator, a frequency divider, a phase comparator and a low-pass filter and measuring a DC voltage of the filter while changing frequency dividing ratios. CONSTITUTION:When a voltage from a low-pass filter 13 is applied to an input terminal 4 of the voltage controlled oscillator (VCO) 1, a signal having a frequency fv is outputted to an output terminal 5. This signal is inputted to a frequency divider 10, where the signal is frequency-divided by fv/N and the result is inputted to the phase comparator 11, where the signal is compared with a frequency f0 of a reference frequency generator 12 to generate a DC voltage in response to the phase difference and the voltage is fed to an input terminal 4 of the VCO1 via the filter 13. The relation of frequency in this case is given as fv=Nf0. Thus, when the output voltage of the low pass filter 13 is measured by a voltmeter 8, the relation of the input voltage versus oscillated frequency of the VCO1 becomes known.
