Abstract: PURPOSE:To reduce error action by providing a DC voltage circuit with a protective circuit consisting of diodes and the like, in an inverter device for feeding AC voltage to an induction motor, and by suppressing recovery current. CONSTITUTION:To an inverter circuit 4 for converting DC voltage due to an AC power source 1 and a converter circuit 2, to AC voltage, and feeding it to an induction motor 5, a protective circuit 8 is connected in parallel with each other. The protective circuit 8 consists of a diode 8a, resistors 8b, 8c, and a capacitor 8d. In a case that switching elements 4a, 4c for composing the arm of the inverter circuit 4 are set in an OFF-state and a current I flows to a DC side through a diode 4b on the side of the anode, when the switching element 4c is turned ON, then recovery current J in the opposite direction flows to the diode 4b. In this case, by the electric charge of the capacitor 8d of the protective circuit 8, the recovery current J is made up for, and the current flowing to a current detector 3 is suppressed.

Title: Optical recording medium
Inventor: KAWASE TAKEO
IPC: G11B11/10
Filed: 1992-03-05
Abstract: PURPOSE:To realize mass production and distribution of music information, video information, and the like by recording binary information while discriminating between two type of regions having heat absorbent layers of different thickness and increasing the recording density through ultra-resolution method. CONSTITUTION:The optical recording medium has two type of regions where the film thickness of heat absorbent layer 105 is different. A target optical recording medium can be obtained by removing excessive heat absorbent layer 105 through dry etching until a target thickness is achieved. Since waveform interference does not take place between pits, the reproduction of high density pit, which is difficult in conventional optical recording medium, can be realized and thereby ultra-high resolution reproduction can be carried out on a recording medium dedicated for reproduction.

Title: Detector for ground-fault of variable voltage and variable frequency power system
Inventor: TAKADA SHINJI
IPC: G01R31/02
Filed: 1983-03-23
Abstract: PURPOSE:To detect surely even a one-phase ground-fault for a low frequency by allowing N-number of zero-phase overvoltage detectors different in set value to correspond to N-number of frequency divisions of a power system due to (N-1)- numbers of frequency detectors different in set value. CONSTITUTION:When electric power from a variable voltage and variable frequency power source 2 passing through an output transformer 3 is supplied to a load AC motor 4 of a variable voltage and variable frequency power system, a pilot generator 7 is interlocked with the motor 4. A ground-fault trouble decision device 11 decides a frequency division corresponding to the frequency of the power system out of three frequency divisions through two frequency detectors 9A and 9B different in set value. One of three zero-phase overvoltage detectors 10A-10C which are different in set value and are connected to an open tertiary winding 31 of the transformer to detect zero-phase overvoltages due to the power system ground-fault is selected in accordance with this frequency division. Consequently, different zero-phase overvoltages are detected with a high sensitivity in accordance with frequencies, and even the one-phase ground-fault of the power system for a low frequency is detected surely.

Title: Abnormality detecting device of secondary air introducing device of internal combustion engine
Inventor: KISHIMOTO YOICHI
IPC: F02D41/16
Filed: 1993-03-11
Abstract: PURPOSE:To prevent the deterioration of exhaust gas emission caused by exces sive deficiency of secondary air to the possible extent and also to self-diagnose abnormal condition of a secondary air introducing device caused by clogging of a secondary air passage in idling state when the rich clamp of the air-fuel ratio is performed. CONSTITUTION:A feedback correction factor alpha in normal driving is calculated by the proportional-plus-integral control of an O2 sensor output VO2, thereby the air-fuel ratio is approximately kept the stoichiometiric air-fuel ratio. The feedback correction factor alpha is fixed to the fixed value alphaIDL in idling. At this time, if the secondary air introducing amount is relatively poor, the O2 sensor output VO2 indicates the rich state, so that the correction factor alphaIDL is gradually decreased and corrected so that the 0. sensor output VO2 may be within the fixed range close to the stoichiometric air-fuel ratio. Since the finally determined correction factor alphaIDL indicates the degree of excessive deficiency of secondary air, when the correction factor is less than the fixed value, the abnormality detecting device diagnoses that the secondary air introducing device 2 is abnormal.
