Title: Method and apparatus for discriminating steel plate
Inventor: ARAKAWA TOMOHIRO
IPC: G01N27/72
Filed: 1986-06-18
Abstract: PURPOSE:To obviate temperature compensation of the apparatus, by making circuit conditions equal before a conversion circuit using two magnetic sensors to discriminate the type of steel to be discriminated in comparison with a reference steel plate. CONSTITUTION:While a plating steel plate (or soft steel) 24 is always kept in contact with an core 14 of a magnetic sensor 18 as a reference steel plate, a steel plate 25 to be discriminated is brought into contact with an core 15 of a magnetic sensor 19. An output signal of an oscillator 12 is distributed equal to the two sensors 18 and 19 by a distribution circuit 13. Current flowing through coils 16 and 17 is converted into voltage, amplified and detected by conversion circuits 20 and 21. Then, an offset value is applied to an output signal of the conversion circuit 20 from a discrimination level adjusting circuit 22 while an output signal of the conversion circuit 21 is applied to a comparator circuit 23 as intact. The comparator circuit 23 compares these signals to output a decision output signal. This makes circuit conditions equal before the conversion circuits 20 and 21, thereby enabling accurate correspondence to changes in the environment such as temperature.

Abstract: PURPOSE:To highly stabilize the oscillation wavelength of a semiconductor laser by externally varying the temperature, injection current value or the refractive index of the waveguide of the laser, thereby varying the oscillation wavelength and coinciding with the absorption beam of CH4 gas in wavelength. CONSTITUTION:A double hetero structure semiconductor laser 1 for oscillating in 0.8-1.8mum band is controlled at its temperature in a constant-temperature oven 2, the refractive index of the active region is varied, or DC bias is controlled to secure the wavelength. That is, AC current is applied through the oscillator 7 to the laser 1 to perform the frequency modulation. The laser light is received through a CH4 cell 3 by a Ge photodetector 5, is amplified by an amplifier 6, and is converted to a DC error signal by a demodulator 10. Subsequently, the AC composnent is removed by a filter 11, and the DC component is fed back through a DC amplifier 9 to the laser 1. In this manner, the refractive index of the active region will vary, and the oscillation wavelength will vary. When this wavelength coincides with the absorption beam of CH4, the output of the photodetector 5 becomes minimum with the result that the DC bias of the laser 1 is controlled to meet at the point.

Inventor: YANO TOMOYA
IPC: G02F1/133
Filed: 1994-06-23
Abstract: PURPOSE:To stably generate a plasma electric discharge regardless of the magnitude of data voltages. CONSTITUTION:Cathode voltages VK1 to VKn-1 of prescribed potential differences with respect to anode potential are successively applied to cathode electrodes 9K1 to 9Kn-1 at each of respective horizontal periods. The polarities of the data voltages DS1 to DSm supplied to data electrodes 51 to 5m for the purpose of AC driving of liquid crystals are inverted at every one horizontal period and at every one frame. The polarities of the data voltages DS1 to DSm are inverted after the prescribed time DELTAt from the point of the start time of the respective horizontal periods, i.e. after the plasma discharge is generated in the discharge channels 12 corresponding to the cathode electrodes applied with the cathode voltages. The data voltages DS1 to DSm written in the horizontal period before one period are supplied as they are to the data electrodes 51 to 5m during the prescribed time DELTAt from the point of the start time of the respective horizontal periods. The rear surface potential of the dielectric sheet just before the cathode voltages are applied to the cathode electrodes is kept at about 0V regardless of the size of the data voltages and, therefore, the plasma discharge is stably generated.

Filed: 1988-06-08
Abstract: PURPOSE:To correspond to the property of a high speed and to improve picture quality by driving a stepper motor by switching the step angle of the stepper motor from the minimum step angle to the maximum step angle as the processing speed of a read picture becomes higher. CONSTITUTION:A sub scanning speed control part 25 selects the phase exciting pattern of the minimum step angle when the picture processing speed of a host device is low and selects the phase exciting pattern of a larger step angle as the picture processing speed becomes higher.

Consequently, the title system can make a sub scanning speed higher according to the processing speed and can correspond to the high-speed processing when the picture processing speed is high, since the system is not forced to execute intermittent driving, the change of the inertia of a driving system is small, and smooth sub scanning can be executed. Thus, the picture quality can be improved, and the high-speed processing can be attained.
