Title: Reset circuit
Inventor: ICHIKAWA YASUFUMI
IPC: G06F1/24
Filed: 1982-09-27
Abstract: PURPOSE:To prevent malfunction of a controller due to runaway of a CPU, by using a rectifier circuit, recitfying a clock signal to obtain a comparison voltage to a reference voltage, in a control circuit using the CPU. CONSTITUTION:A clock signal is generated at a clock signal terminal 6 of the CPU, waveform-shaped, rectified by a rectifier circuit 10, applied to a comparator 2 and compared with the reference voltage VF. When the clock signal is generated normally, a voltage at a reset terminal 4 goes to an H level after a charging time C3R5 seconds after the application of power supply, and reset is applied. If a clock signal generating circuit of the CPU is not operative, since a voltage rectifying the clock signal by the rectifier circuit 10 is taken as the comparison voltage and compared with the reference voltage VF, the output of the comparator 2 remains at an L level, no reset is applied and the CPU is inoperative.

Filed: 1991-07-09
Abstract: PURPOSE:To attain a stable operation test even in a state that a stray capacity is generated in a tester connection part by providing a test mode selecting circuit for driving a switch. CONSTITUTION:When a prescribed voltage is applied to the specific terminal of a microcomputer M, and a signal is outputted from a test mode selection circuit 12, and given to a transfer gate 10 through an inverter 11, the transfer gate 10 is turned off. Thus, an inverter 3 and a frequency dividing circuit 4 are detached, and become a state that an external clock can be imparted to the frequency dividing circuit 4 only from a clock output terminal 2. Therefore, by imparting the signal of a fixed level from a driver circuit 5 to a clock input terminal 1, and inputting a clock outputted from a driver circuit 6 to a clock output terminal 2, a clock is inputted to the frequency dividing circuit 4. The frequency dividing circuit 4 divides the frequency of the clock and imparts it to a circuit part, detects a clock outputted from the circuit part, and by the detected clock, a tester T discriminates the operation of the microcomputer M.

Title: Sail device
Inventor: NARITA HITOSHI
IPC: B63H9/06
Filed: 1980-11-30
Abstract: PURPOSE: To enable to give the optimum camber to a profile sail main body by a structure wherein the profile sail is longitudinally divided and as well as respective unit sails are rotatably connected with one another.  
     CONSTITUTION: The profile sail main body E a  is divided in the same direction as the direction of a mast 5 into three unit sails (a main sail 1, a fore sail 2 and an aft sail 3) rotatably connected with one another and equipped with rotating devices 6 and 7. The respective unit sails 1, 2 and 3 are respectively symmetrical and form as a whole a single symmetrical profile when their center lines are coincided with one another. When the generation of a large lift with said profile is advantageous in spite of a small increase of drag followed, the fore sail 2 and the aft sail 3 are rotated by means of the sail rotating devices 6 and 7 located at before and after the main sail 1 in order to give the profile the optimum camber as the whole sail. At this time, a more larger lift can be generated by blowing the energy of wind into the boundary layer at the back side of the sail main body E a  to prevent the air flow from separating with a straightening sail 4 or 8 pulled out at the back pressure side.

Title: Pattern inspecting device
Inventor: TERAI HIROYUKI
IPC: H05K3/00
Filed: 1991-07-10
Abstract: PURPOSE:To discriminate a real defective pattern gap by scanning a circular and circumferential masks against a pattern to be inspected and excluding one linear mask by regarding the linear mask as a false defect caused by a V-shaped pattern to be inspected when the linear mask is not included in the pattern to be inspected. CONSTITUTION:An adjacent point extraction circuit 6 inputs a circular extracting point signal 35 and circumferential extracting point signal 34 and finds a point of sameness between the signals. Then the circuit 6 outputs an adjacent point signal 36 by using the point as a candidate for a defective gap. A linear mask generation circuit 7 generates a linear mask and, when three lines in the linear mask becomes one line and the one line becomes '0' line, outputs a linear pattern extraction signal 37 by discriminating that a pattern to be inspected is bent in a V-shape at an acute angle. A fault discrimination circuit 8 inputs the signal 36 from the circuit 6 and signal 37 form the circuit 7 and outputs a fault signal 38 which represents a real fault by eliminating a false fault caused by the V-shaped pattern to be inspected from candidates for defective gaps.

Title: Ultrasonic washing device
Inventor: MATSUZAKI NOBUKI
IPC: H01L21/304
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a diaphragm by a washing liquid pressure by providing the above device with a pressure regulating means for maintaining the inside of a space part at a prescribed pressure by relieving part of the washing liquid when the washing liquid supplied into this space part attains the pressure higher than the prescribed pressure. SOLUTION: The washing liquid is supplied from a supply path 31 via an ejection path 32 to the space port 18. Since the rate of the washing liquid supplied into the space part 18 is set higher than the outflow rate from a nozzle part 19, the pressure in the space part 18 increases gradually. The spherical body 36 of a check valve 34 is depressed by the pressure when the pressure in the space part 18 attains the prescribed value and the top end of a discharge path is opened, therefore, the washing liquid is partly relieved therefrom. As a result, the pressure of the washing liquid in the space part 18 is maintained constant. The power feed to a vibrator 24 is started by a controller 30 when the discharge of the washing liquid is detected by a sensor 41.  The diaphragm 21 is then ultrasonically vibrated and the wash is efficiently washed by the washing liquid applied with the ultrasonic vibration.

Filed: 1985-07-30
Abstract: PURPOSE:To simplify the constitution by applying recording and reproduction to same line always at same channel and applying recording and reproduction so that a line number recorded and reproduced is unchanged by a frame at the same time. CONSTITUTION:A missing period of a video signal is provided between frames by a half of the horizontal scanning period after expansion in applying recording and reproduction while the time base of a television signal is expanded twice and divided into 2 channels, the signal is recorded by 1124 lines only so that the same line is recorded and reproduced always on the same channel and the line number subject to recording and reproduction is unchanged depending on the frame at the same time. Unrecorded part is formed for one line at each frame, that is, for a period corresponding to 0.5H after expansion. Since the blanking period exists in general in the television signal, there is no special problem and the relation of H is set at each frame. Thus, the circuit constitution of a recording and reproducing device is simplified.

Filed: 1984-08-13
Abstract: PURPOSE:To make it possible to measure the physical force to be measured among various physical forces without receiving the effect of the other physical forces, by directly connecting a compensation constant polarization optical fiber, which has a characteristic substantially equal to that of a sensor constant polarization optical fiber, to the sensor constant polarization optical fiber. CONSTITUTION:A polarizer 3 is arranged with respect to a compensation constant polarization optical fiber 2 so that linear polarized light is excited in a ratio of 1:1 to the X'- and Y'- directions of a constant polarization optical fiber 2. The constant polarization optical fiber 1 and the constant polarization optical fiber 2 are constituted so as to be made substantially equal in a double refraction index characteristic and same in phase difference. The main axes of both optical fibers are mutually rotated by 90 deg. to be connected so as to be crossed at right angles so that the linear polarized light propagated through the constant polarization optical fiber 2 in the X'-direction is propagated to a Y-direction in the constant polarization optical fiber 1 and that propagated through the constant polarization optical fiber 2 in the Y'-direction is propagated to an X-direction in the constant polarization optical fiber 1 to an X-direction. By this method, when the same temp. is imparted to both of the constant polarization optical fibers 1, 2, the phase difference generated between the polarizations of the sensor constant polarization optical fiber 1 in the X- and Y-directions is cancelled out by that generated between the polarizations of the compensation constant polarization optical fiber 2 in the X'- and Y'-directions.
