Patent JP-S6277055-A (JP)
Title: Chopper device
Inventor: MORI HARUYOSHI
IPC: H02M3/135
Filed: 1985-09-25
Abstract: PURPOSE:To reduce the loss of a circuit, by discharging electric charge via a diode after the electric charge stored in a snubber condenser is moved into the condenser of a series circuit set between a snubber circuit and a load, after a gate turn-off thyristor (GTO) is turned ON. CONSTITUTION:Between a load 2 and a snubber circuit 5, a series resonance circuit 10 consisting of a thyristor 10a, a reactor 10b, and a commutating condenser 10c is connected. The condenser 10c is connected to a spill control diode 3 in parallel with each other via a discharge diode 11. When a GTO 4 is turned OFF, then a snubber condenser 5a is charged with current I4 flowing through the GTO 4, through a snubber diode 5b, and the charge is gradually increased. When the sum of the voltage of the condensers 5a and 10c gets to be equal to power source voltage Ed, then current is conducted to diodes 7b, 11. When the GTO 4 is turned ON, then the thyristor 10a is ignited at the same time or slightly later, and the electric charge of the condenser 5a is shifted into the condenser 10c and is discharged to the load 2. As a result, the loss of the snubber circuit can be reduced.

Title: File destruction detecting system
Inventor: SAITOU JIYOUJI
IPC: G06F12/16
Filed: 1981-12-28
Abstract: PURPOSE:To easily detect destructed files, by writing names of files being updated or newly implemented in a file updating table installed to an external storage medium and by reading out the file name when the power supply is instantaneously interrupted. CONSTITUTION:A memory 2 which is controlled by a CPU1 has a file updating  table 20, a control program 21, and a work for working 22'. A disk device 3 is  provided with a file updating table 30 in addition to planting areas 31 and 32 of  files A and B, and names of files being updated or newly implemented are deposited in the table 30. The area 20 of the memory 2 is used when the file updating table 30 is expanded. When an instantaneous interruption of the power supply is detected 4 while a file is updated (newly implemented), a reset signal  RST is sent to the CPU1 and, after the power supply is restored, the CPU1 extends the content of the file 30 to the area 20 of the memory 2. If ''being updated (newly implemented)'' is recorded when the content is read, the CPU1 detects that the file is destructed and inhibits the use of the file thereafter.

Title: Method for regenerating clock in fsk demodulator and clock regenerator
Inventor: NISHIMURA YOSHIICHI
IPC: H04L27/14
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To provide a stable regenerated clock, regardless of the number of the frequency shift of a multivalued FSK signal. SOLUTION: The sampling signals between one-symbol rate are held in a shift register 3 by sampling the FSK signal demodulated by an FM demodulator 1 at the speed which is 8 times as fast as a symbol rate by a first sampling circuit 2 and inputting the FSK signal in the shift register 3 having 8 registers 3a to 3h. In differentiating circuit 4, the changed quantity of the signal corresponding to a differential value and the changed width of the FSK signal at one-symbol rate space are calculated by the subtraction of the prescribed signals with each other of the shift register 3. In an edge detection circuit 5, it is detected that these become prescribed values.  As a result, an edge pulse is outputted from the edge detection circuit 5, the synchronization in a PLL oscillation circuit 6 is taken and a reproduced clock is inputted from the PLL oscillation circuit 6 for a second sampling circuit 8.

IPC: H04L27/227
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To detect a pseudo pull-in state by positional information of a signal point of a base band signal. SOLUTION: A pseudo pull-in detection circuit detects the pseudo pull-in state by positional information of the signal point expressed by the vector sum of base band signal outputs. At the step of finishing a pull-in process, operation is started (step 101) and the number of signal points existing in a specific area (b) excepting for a normal signal point is counted first (step 102). When this counted value is not less than a prescribed value (step 103) and no signal point exists in the boundary area (a) of the signal point (step 104), the pseudo pull-in state is judged and a detection signal is sent (step 105). In addition, when the counted value is less than the prescribed value and the signal point exists in the boundary area (a) of the signal point at the step 103, a normal pull-in state is judged (step 106).

Title: Rice cooker
Inventor: OMORI HIDEKI
IPC: H05B3/00
Filed: 1992-08-12
Abstract: PURPOSE:To correct the heater power and the rice cooking sequence at the time of cooking rice, and always maintain the excellent rice cooking performance by connecting a temperature sensor and a pressure sensor to a sequence control circuit. CONSTITUTION:A temperature sensor 15 and a pressure sensor 16 are connected to a sequence control circuit 14. A heater 9 consists of a heater element 10 such as a nichrome heater or the like and a TRIAC 11. In the case where the atmospheric pressure detected by the pressure sensor 16 is reduced, the control circuit 14 outputs the command for reducing the heater power during the boiling maintaining period. A heater control circuit 12 reduces the heater power on the basis of that command. As a result, in the case of a low atmospheric pressure, the temperature during the boiling is lower than that of the case of a high atmospheric pressure, but the boiling maintaining time becomes longer than that of the case of a high atmospheric pressure.

Title: Magnetic recording and reproducing device
Inventor: TOMITA MASAMI
IPC: G11B15/665
Filed: 1989-08-21
Abstract: PURPOSE:To prevent an interference noise caused by the vibration of a tape drawing-out means with a guiding groove from occurring by always attracting and holding a part to be attracted by means of an attracting member for the tape drawing-out means at a non drawing-out position. CONSTITUTION:When the tape drawing-out member 4 moves to the non drawing- out position, the part 51 to be attracted which is integrally constituted with the member 4 is attracted and held by the attracting member 50 which is disposed on a base 1. Therefore, the tape drawing-out member is fixed at the position. Since the driving force T1 for the member 4 by a toggle link B25 against the attracting and holding force T3 for the member 4 by the attracting member 50 is made to satisfy T1>T3, the member 4 acts without any failure at the time of drawing out a tape. Thus, the interference noise is not caused even when the vibration is added from the outside.
