Title: Material for indicating exposed heat energy quantity
Inventor: YABUKI YOSHIHARU
IPC: G01N31/22
Filed: 1986-10-20
Abstract: PURPOSE:To inexpensively and surely indicate heat energy quantity by using an acidic color developer, coupler and specific triazene compd. to form a material for indicating the exposed heat energy quantity. CONSTITUTION:A zinc salicylate color developer, etc., are used as the acidic color developer. The compd. expressed by the formula is used as the triazene compd. In the formula, Ar denotes an aryl group, heterocyclic group; R<1>, R<2> denote H, alkyl, cycloalkyl, aralkyl, alkenyl, aryl, heterocyclic group, etc. A compd. which forms color by bonding to the triazene compd. is used as the coupler. The acidic color developer and the triazene compd. are isolated by a microcapsule and three kinds of the compds. are coated on a sheet to form the material for indicating the exposed heat energy quantity. The microcapsule is broken to bring the acidic color developer and the triazene compd. into contact with each other to initiate reaction at the time of using such material. The color density after the specified time when the reaction is accelerated by heat is measured. The exposed heat energy quantity is, therefore, indicated with high accuracy.

Abstract: PURPOSE:To provide a compact heater capable of immediate heating or auxiliary heating by interconnecting an unit for absorbing and emitting hydrogen of metal hydride and utilizing of engine cooling water and a warm water heater of a warm water heater system heater heat-exchangeably through a heat- exchanger. CONSTITUTION:Immediately after the beginning of engine start when temperature 3 of engine cooling water is lower than a set value, a water passing valve 13 is closed, a water passing valve 12 and a hydrogen valve 9 are opened by a controller 14. Thus, engine cooling water is sent to a tank 7 in the direction of arrow by a pump 2. On the other hand, hydrogen gas B in a storage tank 6 flows into a storage tank 7 so that metal hydride A absorbs hydrogen to generate heat, raise temperature of cooling water and heat with radiation of the warm water heater 4. When the cooling water temperature 3 is sufficiently raised, the water passing valve 13 is opened to be changed over to the heating of cooling water. Metal hydride A exchanges 10 heat with high temperature cooling water to emit hydrogen which is absorbed by metal hydride B for generation. By this constitution is obtained the immediate effect of heating.

Filed: 1985-11-09
Abstract: PURPOSE:To expand the logic range of a phase control system without narrowing the control band by comparing the phase of a reference frequency division signal being the result of 1/N frequency division to a reference signal with the phase of a frequency division signal to be compared being the result of 1/N frequency division of the signal subject to phase comparison.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily perform gate pass control by recording a video audio signal in a temporary storage mechanism by a signal switch mechanism by pressing an operation button and simultaneously reproducing the video audio signal at higher speed than the recorded speed and transmitting a reproduced video signal to a video display. SOLUTION: When the operation button 19 is pressed, a control mechanism 17 switches the signal switch mechanism 12, 16, the temporary storage mechanism 14 stores a start address in a storage mechanism 20 and continues to record the video audio signal. And when the operation button 19 is pressed again to cancel absence by a viewer, the control mechanism 17 successively transmits the address stored in the storage mechanism 20 to the temporary storage mechanism 14 from the address where recording is started as continuously turning a light of the operation button 19 on and instructs reproduction of the video audio signal from the address where the recording is started for informing the absence state is canceled. Consequently, the video/audio signal from the start of the absence is displayed on a video display 18.  And the video audio signal is displayed by a fixed time interval of an actual broadcasting signal since reading speed and writing speed of data in the temporary storage mechanism 14 are coincident each other.

Title: Wire speed control method for wire electric discharge machine
Inventor: KATAOKA TAKAYUKI
IPC: B23H7/10
Filed: 1987-10-05
Abstract: PURPOSE:To improve a machining speed without damaging quality, by a method wherein a potential difference between a workpiece and a wire is actually measured, and a difference between a preceding time and a present time of an abnormal potential difference fall controls the increase and decrease of the wire speed. CONSTITUTION:A potential difference between a workpiece and a wire is continuously measured, and a time distance  T between a time when an abnormal potential difference fall is produced due to slight electric short-circuit and a time when a next abnormal potential difference fall is produced is determined. A wire speed V is varied by multiplying constants k1 and k2 so that, when the  T is below a desired minimum value  t1, the moving speed of a wire to the workpiece is decreased, and inversely, when the  T exceeds a desired maximum value at  t2, the speed is decreased. This method enables improvement of a machining speed without exercising an influence on machining quality.

Title: Variable interference device
Inventor: WATANABE MASANORI
IPC: G02B26/00
Filed: 1987-10-06
Abstract: PURPOSE:To secure the precision of a selected wavelength to eliminate the instability by changing the spectral transmittance or the spectral reflectivity in accordance with the change of a displacing mechanism. CONSTITUTION:For the purpose of setting and stabilizing a selected wavelength with a high precision, a space interval between substrates 10 and 20 is detected as the electrostatic capacity between electrodes 15 and 25 and the drive voltage applied to a piezoelectric element 85 is controlled based on the detected value. Electrodes 15 and 25 are connected to an electrostatic capacity detecting circuit 60 through lead wires 16 and 26 respectively, and the detected electrostatic capacity is approximately inversely proportional to a gap (d) between reflection films 11 and 21 and corresponds to the selected wavelength. An electrostatic capacity detection signal 65 is sent to a control circuit 70 and compared with a wavelength set signal 66. The control circuit 70 performs the feedback control of the applied voltage in such direction that the actual selected wavelength is approximated to the set wavelength, and the applied voltage is applied to the piezoelectric element 85 through lead wires 75 and 77 and the piezoelectric element is expanded and contracted in accordance with the applied voltage to adjust the length of the interval (d) between reflection films. Thus, the selected wavelength is set with a high precision and is stabilized.
