Title: Method for measuring thickness of plate by laser beam
Inventor: NAGURA MAKOTO
IPC: G01B11/06
Filed: 1987-01-27
Abstract: PURPOSE:To automatically measure the thickness of transparent material quality in a non-contact state during manufacturing, by a method wherein the deviation distance of respective reflected beams at the time when the transparent material quality is inserted between a laser oscillator and a reflecting mirror and at the time when said material quality is not inserted is detected. CONSTITUTION:M-pieces of transparent plates G1-Gn having the same refractive index (n) and different in a thickness are placed between a laser oscillator L and a reflecting mirror M. The beam V emitted from the oscillator L reaches C while repeats refractive by the respective plates G1-Gn and the beam reflected from the reflecting mirror M repeats refraction by the respective plates G1-Gn to reach the unidimensional image sensor (PSD)P arranged at a right angle to the laser beam. This beam is set to B and the reflected beam from the reflecting mirror M when the plates G1-Gn are not placed is set to beam A. When the distance (d) between the beams A, B on PSDP is detected by PSDP, the total thickness of m-pieces of the plates can be calculated according to a predetermined formula.

CONSTITUTION:A one-conductivity type GaAs first conductor layer 5, a barrier layer 2, in which a plurality of sets of AlAs and GaAs layers are laminated, a one-conductivity type GaAs third semiconductor layer 3, a non-doped AlGaAs second barrier layer 2 and a one- conductivity type GaAs second semiconductor layer 1 are sequentially contacted and laminated. The first conductor layer 5 is contacted with a first electrode 9. The second semiconductor layer 1 is contacted with a second electrode 6. The third semiconductor layer 3 is contacted with a control electrode 7. A negative resistance element is formed in this way. A current Ic, which flows between the semiconductor layers 1 and 3, varies depending on both a voltage VEB between them and a voltage VBC between the semiconductor layers 3 and 5. The negative resistance characteristic is provided between a point, where the VEB (which determines the kinetic energy of hot electrons) corresponds to a value in a mini-band, and a slightly higher value of the VEB. The negative resistance characteristic can be externally modulated with the VBC.

Title: Voltage setting device
Inventor: KITAMURA SATORU
IPC: H02P9/30
Filed: 1978-02-20
Abstract: PURPOSE: To enable high reliable voltage setting by connecting a shunt resistor circuit which has the specified resistivity ratio with that between each set of the variable resistor of a multiple variable resistor and a series resistor to a constant voltage power supply.  
     CONSTITUTION: The fixed resistors 21A and 21B are connected to the multiple variable resistors 22A and 22B in series, respectively, and to the DC power supply VB. A shunt device consisting of the fixed resistors 25 and 26 is connected in parallel to this power supply VB. On the other hand, the series circuit of the output resistor 23 and the diodes 24A and 24B is connected between the neutral point of this shunt device and the multiple variable resistor. The higher voltage of the voltages V 11  and V 12  obtained by adjusting the multiple variable resistor is selected by the diodes 24A and 24B. When V 12  is higher than V 11 , the differential voltage against the neutral potential V 3  of the shunt device is obtained. That is, V c  = V 12  - V 3 . Since the multiple variable resistor is used like this, high reliable voltage can be set without giving any bad effect on output voltage even if a contact failure occurs in one variable resistor.

Abstract: PURPOSE: To shorter a processing time and to reduce the necessary capacity of an external storage medium by thinning data and storing the thinned data at the time of storing operational data in an external storage device. CONSTITUTION: A CPU 4b outputs a control signal to turn a floppy disk controlling device 9a to a driven state. Then a controller 4 executes format processing for data read out from a RAM 4d or the like in accordance with the sort of an external storage device 9 and transfers the processed data to the device 9 through an I/O port 4a. The data stored in the RAM 4d are thinned and the thinned data are stored in the device 9 by an operation key switch 6. Namely the start of storage and the setting of an end point are executed at first. Then a data sort (an ASCII signal or a binary signal) is selected. In this case, an ASCII signal is selected and then a thinning interval is set up. Consequently the device 9 can store data at an optional thinning interval.

Abstract: PURPOSE:To allow a remaining feeder to continue the communication without being affected entirely even if a fault being one open feeder takes place by using a relay electromagnet and a relay so as to make the feeders independently of each other. CONSTITUTION:A relay electromagnet coil 1 energizes a relay 4 and a relay electromagnet coil 2 energizes a relay 5 and each relay is in OFF state when no current flows to the feer and in the ON state when a prescribed current flows to the feeder.

Even if one of the feeders 12, 13 is opened, the remaining feeder receives any effect and the communication is enabled similarly. Moreover, the feeding ON/OFF is applied similarly by using the remaining two feeders.

Abstract: PURPOSE:To read out correctly defective loop information by adding a top bit discriminating code consisting of continuous numerics longer than those of a defective loop at the head in an inner loop defective information. CONSTITUTION:A minor loop in a part enclosed with oblique lines shows a defective loop among minor loop groups 2 having the minor loop numbers a1- an. It is assumed that a defective loop and a normal loop are ''1'' and ''0'', respectively, in terms of defective loop display. If a head bit discriminating code is assumed to be continuous ''1'' of 10 bit, defective loop information 12 is stored in a loop 3 so that it will be connected to a head bit discriminating code 13 as shown in the 3rd figure. Here, interference bits 11 are added ahead of the head bit discriminating code 13 and the defective loop information 12; therefore said code 13 can be correctly detected.

Abstract: PURPOSE:To perform satisfactory intermediate image recording without deterioration of image quality due to bridging process by using two types of recording scan line such as the first recording scan line type and the second recording scan line type alternately for each one recording scan line. CONSTITUTION:A switch 24 and a switch 26 are alternately turned ON each time data equal to a single pixel is entered by reversing an output from D-FF28 as soon as data equal to a single pixel. Consequently, the first pixel data generated by a matrix generation circuit 21 and the third image data generated by a matrix generation circuit 23 are alternately output for each pixel. In addition, if pixel data of the third line is entered, the output from D-FF 3 is again reversed, and the switch 24 and switch 25 are alternately turned ON as is the case with the first line. Image data where the first image data and the second image data are alternately present, and image data where the first image data and the third image data are alternately present are alternately output by a single line by repeating the mentioned action.

Abstract: PURPOSE:To correct the phase difference between a reference signal and an error signal while an influence on a passing-signal amplitude characteristic is reduced by a method wherein a detection phase and a changeover switching circuit are changed over by an external control signal. CONSTITUTION:A reference signal 1 and an error signal 2 are composed 7, and the AM modulated wave of the reference signal by the error signal is obtained. At this time, a part of the output of a clock-signal generator 8 is phase-inverted by an inverter 5. A switching circuit 2 changes over a switch according to an external control signal 30, and it sends the output signal of the generator 8 to a synchronous detector 17. A part of the output of a frequency divider 9 is phase-inverted by an inverter 24. A switching circuit 26 changes over a switch 4 according to an external control signal 29, and it sends the output signal of the frequency divider 9 to a switching circuit 18. When the changeover of the circuits 26, 2 is combined, the output of the detector 17 has four envelope detection characteristics. Consequently, when the phase of the error signal is deviated due to a temperature change or the like, the phase is made variable within the whole range of 0 to 20pi by changing the phase setting of a 0 to pi/2 variable phase device 28 and the setting of the circuits 26, 2, and a phase difference can be corrected.
