Abstract: PURPOSE:To enable the accurate measurement of a liquid level even when numerous bubbles exist at the position of the liquid level, by applying rays of light from a position on one side of a bottle and below the liquid level to the portion of this level on the side of a light-receiving camera disposed on the other side of the bottle. CONSTITUTION:A light source assembly 15 comprising a light source 17and a diffusion plate 1 is set so that rays 19 of light emitted therefrom are applied from a position below the level 12 of a liquid 11 in a bottle 10 to the portion 20 of the liquid lvel on the side of a light-receiving camera 16. The rays of light applied to the portion 20 of the liquid level are reflected diffusely on a boundary surface between bubbles 13 existing numerously at the position of the liquid level and the liquid 11, and these rays reflected diffusely are transmitted through the wall of the bottle 10 and received by the light-receiving camera 16. The rays received by the light-receiving camera 16 are converted into voltages by a photoelectric converter 30 and displayed as a bright stripe-shaped portion 31 indicating the position of the liquid level 12 by a display means.

Title: Synchronous switching mode electric source
Inventor: JIYOBANNI MIKEERE REONARUDEI
IPC: H02M3/335
Filed: 1990-03-06
Abstract: PURPOSE: To synchronize the operation of a chopper transistor with a horizontal scanning frequency by responding to a synchronous input signal at frequency related with a deflection frequency while using a transformer having two winding wires, and periodically supplying a low impedance between both the ends of the 2nd winding wire through 2nd switching connected to the 2nd winding wire. CONSTITUTION: A switching transistor Q4 is connected between both the ends of a secondary winding wire W3 at a transformer T1 through a diode D400 and a current limit resistor R400 having a low resistance value. While transistors Q1 and Q2 are conducted, the transistor Q4 is turned on, and the transistor Q4 is turned by a flyback pulse VH at horizontal frequency extracted from a horizontal deflection circuit. Thus, the transistor Q4 applies the low impedance, with which load is applied to the transformer T1, between both the end of the winding wire W3 and generates stepwise increase in a collector current i1 of the transistor Q1. Thus, the timing of switching in a switch mode power source 300 is synchronized with the horizontal scanning frequency.

Title: Partial discharge detector
Inventor: MARUYAMA SHIRO
IPC: H02B13/065
Filed: 1990-03-09
Abstract: PURPOSE:To detect partial discharge pulse accurately with no influence of external noise by detecting a partial discharge signal and a commercial frequency signal separately by means of a floating electrode arranged at an insulating spacer section and detecting a main circuit voltage phase signal from the commercial frequency signal thereby detecting a partial discharge of random phase. CONSTITUTION:A signal having specific frequency separated through a bandpass filter 13 located in a detecting section 7 contains noise which can not be removed even after the signal is converted into a constant pulse signal through a peak hold circuit 16. When the signal having specific frequency is subjected to A/D Conversion through an A/D converter 28 only during the duration of a measuring timing pulse output, it shows that the pulse having specific frequency exists in a part of phase where the noise is hard to be discriminated thus increasing the probability for judging the pulse having specific frequency as a partial discharge pulse. Consequently, detection accuracy is improved as compared with a conventional method where judgment is made based only on the existence of specific frequency pulse corresponding to the partial discharge pulse.

Filed: 1980-04-28
Abstract: PURPOSE:To efficiency perform the large speed control of a motor by providing intermediate taps at the armature winding of a brushless motor and switching the number of turns of the armature winding in response to the desired load and rotating speed. CONSTITUTION:A driving circuit 7 controls to drive armature windings 1-1-1-3 by a position detection signal from a position detector circuit using a Hall element or the like. Since the right ends of the respective armature windings are short-circuitted when the transistor 6 of a switching circuit B is turned ON and a transistor 5 of a switching circuit A is turned OFF in a mode 1, the supplied voltage from the driving circuit 7 is applied to the overall of the armature windings. Since the respective armature windings of the right end are opened by the short-circuit of the respective intermediate taps in the circuit A when the transistor 5 is turned ON and the transistor 6 is turned OFF in mode 2, the supplied voltage from the driving circuit 7 is applied to the winding part of the left side from the intermediate tap. Since the counterelectromotive force constant and the torque constant in the mode 1 are larger than those in the mode 2, it is adapted for low speed and high torque load, and the mode 2 is adapted for high speed and low torque load.
