Title: Solid-state image pickup device
Inventor: WATANABE HIROYUKI
IPC: H04N1/19
Filed: 1987-09-18
Abstract: PURPOSE:To eliminate a condenser lens and to simplify the structure of a solid- state image pickup device by making the thickness of a glass tube wall of a fluorescent tube uneven and forming a lens on a part of the wall in the solid- state image pickup device forming the fluorescent tube as a light source. CONSTITUTION:The thickness of a part of the glass tube 102 of the fluorescent tube 101 is changed to form a lens. A light emitting substance 103 is not applied to the lens part 104 and the part 104 is formed as an aperture. Thereby, brightness on the surface of the light emitting substance 103 can be extracted without attenuating it brightness can be obtained because of the light converging effect of the lens. Light projected from the fluorescent tube 101 lights up the surface 105 of an original. Information on the original surface 105 is formed on an equal scale type image pickup element 107 and converted into an electric signal by the element 107. Since the light source and the condenser lens can be formed as united structure, positioning of both the elements can be eliminated and handling can be simplified.

Abstract: PURPOSE:To remove a signal having noise-like characteristics such as chattering by repeatedly cancelling edge detection of a signal to be detected during the continuation of a detecting signal state different from an ordinary detecting signal state for a prescribed period after detecting the edge of the signal to be detected. CONSTITUTION:At the time of generating an output from a discrepancy detecting circuit EX-OR for detecting a discrepancy between a stored signal precedently arriving at a flip flop FF-T and a current signal to be detected, the length of the signal coincident with the preceding arriving signal is measured by a counter CO2, the continuation of the signal state of an ordinary arriving signal for a prescribed time T after detecting the edge of the signal (b) to be detected is measured by a counter CO3 and the passage of a prescribed time T1 after the edge detection of the signal (b) is measured by a counter CO1. When a detecting signal state different from the ordinary detecting signal state is continued for a prescribed time, the edge detection of the signal (b) is repeatedly cancelled and the edge of the signal (b) to be detected is detected when a noise state such as chattering is removed.

Abstract: PURPOSE:To automate the optimum charging operation of an electric precipitator, by using a value obtained by operational processing on the basis of a specific voltage value as a control index and operating the electric precipitator at spark frequency bringing the value to a max. one. CONSTITUTION:The instantaneous value VEP of the voltage signal obtained by a voltage detector receives operational processing in an operation apparatus 9. The operation apparatus 9 multiplies the max. voltage V1 for a certain period immediately before an operational cycle is started and the average value V2 for a separate period immediately before the operational cycle is started to calculate a control index Ixc. This index value Ixc is used as an index in an automatic setting device 10 and the setting signal of spark frequency is outputted to a thyristor control apparatus 1 and the ignition signal of a thyristor is controlled. As a result, because spark frequency is set always optimumly, operation for maximum dust collection efficiency can be kept.

Title: Arc spot welding
Inventor: TOYOHARA TSUTOMU
IPC: B23K9/025
Filed: 1984-11-09
Abstract: PURPOSE:To perform welding at high efficiency with proper depth of penetration, diameter of deposition and quantity of deposition according to plate thickness even when an upper plate is thick, by superposing an upper plate and a lower plate and then piercing a hole with a diameter calculated by a specific formula, and welding the plates. CONSTITUTION:A hole having a diameter expressed by the following formula is pierced in the upper plate. D0<=(WX4/t1XdeltaXpi)<1/2> where D0=hole diameter, W=quantity of melting of wire, t1=thickness of upper plate, delta=specific gravity of plate. Proper hole diameter changes depending on thickness of the upper plate. It is necessary to make the quantity of melting of the welding wire 6 and the size of the hole (area Xplate thickness). The quantity of melting of the wire 6 in arc spot welding is nearly within a fixed range, and the size of the hole must be smaller than this. When a specified hole (d) is pierced in the upper hole, the arc 5 hits directly on the lower plate 2 immediately after starting by arc pressure, and penetration of the lower plate is formed. With the lapse of time, outer periphery 7 of hole (d) of the upper plate is molten, and further, the welding wire 6 is also molten, and finally, the whole hole is filled up. Deposition diameter C nearly equal to the hole diameter is obtained be tween upper and lower plates, and desired welded plates are obtained.

IPC: H01S3/03
Filed: 1988-09-22
Abstract: PURPOSE:To stabilize the frequency of the title laser within a wide range by impressing a specific static magnetic field upon the inside of the laser thin tube and, at the same time, feedback controlling the resonator length by utilizing the intensity difference or intensity ratio between adjacent longitudinal modes as an error signal after detecting the difference or ratio. CONSTITUTION:The 543-nm He-Ne laser light oscillated from a laser tube LA is separated into light components respectively having inherent polarizing directions C1 and C2 at a polarization beam splitter PBS and the components are respectively detected and amplified by means of PIN photodiodes PD1 and PD2 and amplifiers AM1 and AM2 as DCs. Outputs of the amplifiers AM1 and AM2 are inputted to a differential amplifier DA where an intensity difference between the light components is detected. The intensity difference is outputted from the amplifier DA as an error signal after amplification and the collector current of a transistor Tr2 is controlled from the amplified error signal. Then the electric power supplied to a heater HE is controlled by the controlled collector current and the resonator length of the laser tube LA is corrected. Therefore, the longitudinal mode can be stabilized to a fixed frequency position.

Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To surely determine a stopping position y driving a driving means with a delay becoming gradually longer than a reference value or a back pulse becoming gradually shorter than the reference value in accordance with the number of retrying modes at the time of odd numbered retryings and with a delay becoming gradually shorter than a reference value or a back pulse becoming gradually longer than a reference value in accordance with the number of retrying modes at the time of even numbered retryings. SOLUTION: A stocker is rotated by supplying a braking signal to a driving motor in a first retrying mode state and an address is counted based on detection outputs of photo-interrupters S1 to S3 and the braking signal is supplied to the motor when outputs of interrupters S1, S2 are both low levels. Whether both detection outputs of the interrupters S1, S2 are low levels or not is decided and when an answer is 'yes', operations are completed. When a retrying is to be performed at an nth time, the stocker is made to be stopped by reducing the impression time by 5×n/2 (ms) from the back pulse (30 ms) being a reference value when (n) is an even number and by increasing the impression time by 5×(n-1)/2 (ms) from the back pulse (30 ms) being the reference value when (n) is an odd number.
