Title: Brushless exciter field ground-fault trouble detector
Inventor: ISHIZUKI TERUYUKI
IPC: H02K19/36
Filed: 1990-05-30
Abstract: PURPOSE:To eliminate an erroneous operation due to a residual magnetic flux by demagnetizing, by a demagnetizing unit, the flux remaining in a detecting winding core after a trouble is removed. CONSTITUTION:If a trouble occurs, a current flows to a rotor side detecting winding 4, and a detector 6 detects it as a trouble. Here, after a generator is excited in a no load state, the generator is stopped as remained in a constant- excited state by the exciting current of an AC exciter corresponding to the exciting current. Since a voltage induced in an auxiliary winding 2 is AC and proportional to the rotating speed of the generator, a trouble current flowing to the winding 4 is gradually reduced as the rotating speed is reduced by the stopping operation of the generator. Accordingly, a magnetic flux passing through the core of the winding 4 becomes a gradually reducing AC magnetic flux, and its residual magnetic flux is converged to zero when the generator is stopped. Thus, demagnetization of the residual flux can be automated.

Abstract: PURPOSE:To control the reflectivity of an end face with less number of steps and good controllability by so forming a dielectric film as to cover the whole face of a multilayer structure having a deeper stripelike groove than an active region, and covering the grooves at every other one with a mask to form a metal film or a dielectric multilayer film. CONSTITUTION:A multilayer structure having an active region 2 is formed, a plurality of deeper grooves than the region 2 are formed in a stripelike state, and a dielectric film 6 is so formed as to cover the whole surface of the structure formed with the grooves. Then, the grooves are covered at every other one with a mask 8, and a metal film 7 or a dielectric multilayer film is formed on the whole surface except the grooves covered with the masks 8. For example, after the film 6 is formed, a window is opened at the film 6 of the flat section except the grooves, the grooves are covered at every other one with the masks 8, and metal for forming a reflection film is deposited on one side resonator end face. Thereafter, after the mask 8 is removed, it is cut at the center of the mask 8, and further cut in a direction perpendicular to the groove to manufacture a sole wavelength oscillation semiconductor laser chip.

Title: Inverter
Inventor: NISHINO HIROYUKI
IPC: H02M7/48
Filed: 1985-06-25
Abstract: PURPOSE:To prevent a switching element from damaging due to a rush current by supplying a discharge current due to the remaining charge of a resonance capacitor through a load or an inductance element to the switching element. CONSTITUTION:When the drive frequency of a transistor 4 increases or a load impedance increases due to the state change of a load Z, the transistor 4 is conducted before the collector voltage of the transistor 4 becomes zero, and the remaining charge of a resonance capacitor 7 is discharged. This discharging current flows from the capacitor 7 toward the collector of the transistor 4, but since the load Z is interposed in the midway, it does not become a rush current. If the load Z is removed, the discharging current flows through an inductance 3 and the secondary winding of a transformer 2, and its flow rate is limited.

Abstract: PURPOSE:To improve the reliability and eliminate any defect of a temperature relay due to external force by covering the temperature relay with a soft insulating material and by molding a printed circuit board and a stator core in one united body with premix. CONSTITUTION:A winding 2 is provided for a stator core 1, and a temperature relay covered with a soft insulating material 3 is mounted to a printed circuit board 5.

Abstract: PURPOSE:To indicate time simply while facilitating the timing by generating an alarm tone when switches are operated corresponding to the current time by arranging a plurality of minute switches corresponding to minutes per a specified unit and an hour switch corresponding to an hour. CONSTITUTION:When one wants to know the current time, a switch ST is depressed to produce an output for selecting the current time from a switching circuit SW. This output activates a selection circuit SE to select outputs of counters MT and HT and a discriminator circuit AP1. The outputs from the counters MT and HT are fed to a coincidence circuit CN2 while the output of the circuit AP1 is fed to an alarm control circuit AL and the alarm tone is differentiated between a.m. and p.m. On the other hand, outputs of encoders EM and EH are fed to the circuit CN2. Code outputs are generated separately for one, two o'clock-noon from the encoder EM when switches H1-H12 are depressed. When the current time is the same as the alarm time, an incidence output is generated from a terminal (n) of a circuit CN1 to produce an alarm tone from a sound generator SP.

Abstract: PURPOSE:To detect easily the fitting state of a charger wire by loading an auxiliary body having plural electrodes in insulated states each other so that it can be pulled out, instead of an electrostatic charged body and connecting an electrostatic charge amount measuring means between each electrode and the earth terminal of a unit. CONSTITUTION:The auxiliary body is an oblong body having length in an axial direction approximately the same as the electrostatic charged body loaded on the unit and the same diameter as said body. By interposing insulating bodies 10 on both ends in the axial direction and in the center, two electrodes 5 are formed, which are insulated each other. Then the electrostatic charge amount measuring instrument 11 is connected between each electrode 5 and the earth point of the unit.
