Title: Controller for circuit breaker
Inventor: KUSANO YOUSUKE
IPC: H02H3/08
Filed: 1978-05-15
Abstract: PURPOSE: To quickly open a circuit breaker with regard to both a forward current and a recerse current, by amplifying the current of a magnetism-electricity converter provided in a conductor of a main circuit and by discharging a commutation capacitor by forward and recerse pulse generators to actuate a trip unit when the amplified current has reached a setpoint.  
     CONSTITUTION: When the output of the magnetism-electricity converter 2 such as a Hall element placed in a gap 1a of an iron core 16 surrounding the main circuit conductor 1 of the circuit breaker is amplified to the setpoint by an amplifier 3, a first generator 7 or a second generator 8 produces a gate pulse depending on the direction of the main current to turn on a thyristor 11 through an OR circuit consisting of diodes 9, 10 to start the trip unit. Thyristors 12, 13 or thyristors 14, 15 are triggered depending on the direction of the main current, with a time difference from the thyristor 11, which is proviously set in the pulse generators 7, 8, so that the current is made zero by the commutation capacitor at the time of contact opening of the circuit breaker. The circuit breaker is thus quickly opened with regard to both the directions of the current.

Abstract: PURPOSE:To improve yield by doubling in construction all capacitors concerned with Z<-1> which is the parameter of the transfer function of a low-pass switched capacitor(SC) filter whose worst sensitivity goes to '0', and converting the parameter Z<-1> into Z<-2>. CONSTITUTION:The low-pass switched capacitor filter whose worst sensitivity to element deviation goes to '0' at a 0 frequency designed strictly based on a bilinear S-Z conversion is used. All the capacitors concerned with the Z<-1> which is the parameter of the transfer function of this filter are doubled (CK1, CK2, CA11, CA31 and CA52) and the parameter Z<-1> is converted into the Z<-2>. Thus, its central frequency is determined only by a clock frequency, is not influenced by the deviation of the values of the capacitors, therefore, the central frequency can be changed by changing the clock frequency simultaneously. By making the worst sensitivity of the low-pass SC filter at the '0' frequency to '0', the worst sensitivity at the central frequency goes to 0.

Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To perform prevention of theft even when a trouble, such as short circuit, occurs to a source line to a device to prevent the occurrence of theft through collation with an authentication code. SOLUTION: When an engine control device having a theft prevention function decides that the number N of revolutions of an engine is reduced to 0r.p.m. at a step 505, it is decided at a step 535. When it is decided that a given time elapses, an authentication code from the key of a vehicle is re-collated with an authentication code prestored on the vehicle side whether a given time elapses. When it is decided that the two authentication codes do not coincide with each other at a step 545, a theft decision flag is set to 1 at a step 545. When the theft decision flag is set to 1, the engine control device stops the starting of an engine. Thus, even when a trouble, such as short circuit, occurs to a source line to the engine control device, theft prevention is carried out.

Title: Synchronizing circuit
Inventor: KARIYADO AKIRA
IPC: H04N5/04
Filed: 1980-05-01
Abstract: PURPOSE:To synchronize the counting operation of a counter circuit with a repetitive signal accurately by resetting the counting operation after putting an inhibit pulse and reset pulse in phase when both the pulses become out of phase. CONSTITUTION:Counter correcting circuit 17 receives pulse P1 which synchronizes with horizontal synchronizing signal SH from AFC circuit 13 and outputs reset pulse P2. Simultaneously, circuit 17, when inhibition pulse P4 and pulse P2 are in phase with each other, checks the generation position of pulse P2 in evey horizontal scanning period and then integrates the detection result to detect where pulse P2 are generated most frequently. Once this position is detected, counter circuit 15 is reset on the basis of the position. When pulses P4 and P2 become out of phase, on the other hand, circuit 17 supplies an integrating-operation stop signal to ROM circuit 16. Then, pulses P4 and P2 are put in phase to add successively pulses P2.

Title: Cryostat for superconductive coil
Inventor: MITSUNE SUSUMU
IPC: H01L39/04
Filed: 1978-05-17
Abstract: PURPOSE: To reduce the consumption of liquid helium by providing a lampshade- shaped container which covers a superconductive coil from its upper side.  
     CONSTITUTION: When coil 3 is in a superconductive state, the liquid-helium surface inside lampshade-shaped container 6 is equal in level to that outside of it. When coil 3 changes into a normal conductive state, liquid helium 4 starts vaporing through the heating of coil 3 and helium gas stays inside of container 6 so as to increase the pressure inside of container 6; and then, the liquid surface of liquid helium in container 6 is caused to fall down and coil 3 is separated from liquid helium and covered with helium gas instead. The sensible heat of helium gas is  much larger than its latent heat, which results in that the heat of coil 3 is absorbed.  The gas pressure inside of container 6 is controlled by valve 8 not to leak the gas from the lower part of cotainer 6. After the vaporing of the gas ends, the liquid surface is returned to the original level by valve 8.

Title: Vehicle with automatically controlled clutch
Inventor: HAYASHI NOBUHIKO
IPC: B60W10/18
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To smoothly stop a vehicle by adapting a small hysteresis width when a brake pedal is depressed, and adapting a large hysteresis width when no brake pedal is depressed. SOLUTION: When no brake pedal is depressed, a clutch-on/off map during coasting for a large hysteresis width is adapted to make clutch-on/off control (step 3). When the large hysteresis width is adapted, clutch-on/off hunting can be prevented. When the brake pedal is depressed, the clutch-on/off map during coasting for a small hysteresis width is adapted to make clutch-on/off control (step 4). Since the brake pedal is depressed, it is judged that a driver intends to stop a vehicle. When the clutch-on/off map during coasting for the small hysteresis width is adapted in this case, a clutch is disengaged slightly early, and the vehicle can be smoothly stopped.
