Title: Semiconductor device
Inventor: OHORI TATSUYA
IPC: H01L29/812
Filed: 1987-03-19
Abstract: PURPOSE:To obtain a large current by making a channel layer a super-lattice consisting of a GaAs film and an InAs film. CONSTITUTION:A channel layer consisting of the super-lattice of a GaAs film, e.g., a GaAs film 13A and an InAs film, e.g., an InAs film 13B, made of, e.g., a super-lattice 13 and wherein a two dimensional carrier gas layer is formed provided on an semi insulating GaAs substrate, e.g., a semi-insulating GaAs substrate 11 and a carrier supply layer which is formed on the channel layer and has wider energy band gap in comparison with the channel layer, e.g., an n-type AlGaAs electron supply layer 14 are provided. Accordingly, a large quantity of carrier can be stored in the two-dimensional carrier gas layer since the carrier running in the channel layer is made high speed without undergoing alloy scattering at a low temperature and an energy band structure can be made the same as that in the case that InGaAs is made a channel layer. This enables obtaining a great current.

Title: Earth leakage breaker
Inventor: YAMADA YUKIE
IPC: H01H83/22
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To miniaturize an earth leakage breaker and equalize the dimension to that of a circuit breaker, by using a given earth leakage breaker wherein a zero-phase current transformer is arranged between from the power source side terminal to a make and break contact to a load side terminal in the main circuit. SOLUTION: In this earth leakage breaker, a leak current is detected by using a leak current detection and tripping circuit, connected to a zero-phase current transformer (provided so as to be penetrated by respective phase power source side fixed conductors), and a make and break mechanism is tripped by a leak current trip device. A current, flowing in a load side fixed conductor, is detected by a current transformer 131 to be supplied to an overcurrent detecting and trip circuit 132; and when an overcurrent is detected, an overcurrent trip device 133 is driven based on a preset overcurrent trip characteristic to trip the make and break mechanism. The removal of the zero-phase current transformer, etc., from a power source side can obtain a circuit breaker to easily manufacture the leak current breaker and the circuit breaker in the same external dimension.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To make possible an inquiring machine to select proper information out of a long series of data in a short time by providing each transponder with a plurality of registers containing data and selecting data in one register out of them. SOLUTION: When an RF signal from an inquiring machine is received with an antenna 40 of a transponder, a data selector 49 selects one out of a plurality of data registers 48 holding response data for the inquiring machine according to a counter 47 valve and supplies the output to a code generator 42 to code the meaning. A modulator 43 modulates the coded signal on the carrier wave (RF) received with the antenna 40, supplies it as response signal from an attenuater 44 to the antenna 40, and transmits the response signal to the inquiring machine. If an article is taken out through a check out, the transponder modulates 43 the signal so as to reduce the power level and prevent erroneous functioning of the robbery gate. In normal power mode, the trnasponder detects an anomaly and generates an alarm.

Title: Rotor of rotary electric machine
Inventor: TOKUMASU TADASHI
IPC: H02K1/26
Filed: 1983-04-12
Abstract: PURPOSE:To alleviate the concentration of a loss due to an eddy current of a cross slot by continuing one side of peripheral ends of the cross slots formed on a lumped core to the coil slot adjacent to a pole. CONSTITUTION:A coil 6 inserted into a coil slot 7 is held by a wedge 2 without radially flying out. A pluraity of cross slots 5 are formed longitudinally of an axis on the suface of the pole 4. The slots 5 are displaced from the center of the pole so that one end is arrived at the adjacent slot 7a. The slots 5 are displaced alternately toward the different adjacent slot 7a side by considering the balance of the shaft rigidity. Since a gap 8 to the adjacent slot 7a becomes at only one side when the slots 5 are disposed in this manner, the flow of an eddy current is limited.

Title: Digital optical communication system
Inventor: OTA YUSUKE
IPC: H04B10/43
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the pre-amplifier noises of a DC coupling burst mode receiver of the conventional technology by applying the DC coupling between a main pre-amplifier of an optical burst mode receiver and a compactor by tracking the changes of the supply voltage, the temperature, etc., that affect the main pre-amplifier by means of a tracing pre-amplifier having the same constitution as the main pre-amplifier. SOLUTION: The DC levels caused by the signals supplied to a single input of an operational amplifier 1-5 from a main pre-amplifier 103 must be accurately matched with each other by another input of the pre-amplifier 103 in order to detect the accurate value of the optical signal that is electrically converted. A tracking pre-amplifier 107 which is substantially equal to the pre-amplifier 103 is monolithically provided on the same integrated circuit as the pre-amplifier 103 in order to attain the said matching of DC levels. As a result, the doubling of pre-amplifier noises of a DC coupling optical receiver can be eliminated in the digital optical communication where the burst mode transmission is performed.

Abstract: PROBLEM TO BE SOLVED: To prevent the interruption of a focus servo operation or a tracking servo operation by preventing the operation of servo sampling in a shortest space zone during an unstable photodetection output immediately after switching from a reproducing mode to a recording mode. SOLUTION: The generation of a sampling pulse is performed based on an EFM signal corresponding to a signal recorded by an optical recording medium. A sampling signal is generated in such a manner that when the EFM signal is inputted to a sampling pulse generation circuit, the sampling pulse is set to an H level after the passage of a first delay time Dt1 from its falling and it is set to an L level when a time until the rising of a next EFM signal reaches a second delay time Dt2. The first and second delay times are lengthened to be properly set by replace third and fourth delay times Dt1' and Dt2', and thereby a shortest zone length is set among space zones where the sampling signal is set to the H level.
