Title: Induction rule by variation of angular velocity
Inventor: KAMIMURA MUTSUJI
IPC: G01P15/16
Filed: 1983-08-13
Abstract: PURPOSE:To measure an angular acceleration, etc. by using a theory that an induction voltage is induced in a coil, when an angular velocity of an electric conductor rotating at a high speed is varied. CONSTITUTION:When an electric conductor rod 1 is rotated 2 at a high speed, a magnetic field 3 passing through the electric conductor rod 1 is generated. When an angular velocity W of the high speed rotation 2 is constant, the magnetic field 3 passing through a coil 4 is constant, but when the angular velocity W is varied, the magnetic field 3 passing through the coil 4 is varied, an induction current flows to the coil 4, and a galvanometer 5 is deflected. In case the electric conductor 1 is a ferromagnetic material, a relation of an angular velocity and magnetization is not linear, but when a ferromagnetic material rod is used, an induction voltage induced by a variation of the angular velocity W is larger than that of other electric conductor rod. Also, even when the angular velocity W of the electric conductor 1 is made constant and the electric conductor 1 is moved in the vicinity of the coil 4, the magnetic field 3 is varied, therefore, the galvanometer 5 is deflected.

Title: Laser oscillator
Inventor: KARASAKI HIDEHIKO
IPC: B23K26/00
Filed: 1990-06-05
Abstract: PURPOSE:To unify out voltage and hence stabilize laser output by detecting the AC voltage of a power source and controlling switching frequency in conformity with the range of fluctuations in reference signal. CONSTITUTION:When the AC voltage of a power source fluctuates, the fluctuations are detected by a voltage detector 21, which enters the detected data into an error amplifier 22. On the other hand, the reference voltage of a reference voltage signal generation circuit 24 enters the error amplifier 22. The difference is input into an output setting circuit 28. The circuit 26 controls the switching on time of a switching low voltage power source so as to unify the power and outputs the controlled power. A drive circuit 23 switches a switching device based on switching time and the switching frequency fixed from a switching frequency setting circuit 29. The control of the switching time in this manner makes it possible to stabilize laser power where the output power from the high voltage power supply source does not depend on the voltage of the power source.
