Title: Formation of magnetic bubble memory element
Inventor: MAJIMA NIWAJI
IPC: G11C11/14
Filed: 1984-05-28
Abstract: PURPOSE:To remedy a chip where a ''Permalloy(R)'' pattern defect occurs in case of the occurrence by detecting and removing a defective minor loop in a wafer state. CONSTITUTION:A swap gate 16, replicate gate 17, and detector 15 are connected electrically to the chip 10 of the magnetic bubble memory element in the wafer state with a probe pin. Then, the chip 10 is placed in an atmosphere of high temperature, a high driving magnetic field, and a low bias magnetic field and then a high bias magnetic field is applied to erase all magnetic bubbles. Then, a specific current is flowed to the detector 15 and the gate which connects minor loops 13-1, 13-2... and when a bubble signal is detected by the detector 15, a loop where a new creation error occurs is detected among the loops 13-1, 13-2... from the difference between the number of cycles where a current is flowed and the difference of cycles where the signal of the detector 15 is detected. Then, nearly the whole ''Permalloy(R)'' pattern of the defective loop is removed by photoetching and even if a ''Permalloy(R)'' pattern defects occurs, its chip is remedied.

Title: Optical disk device
Inventor: HARADA TOSHIHISA
IPC: G11B7/085
Filed: 1991-04-12
Abstract: PURPOSE:To perform the track access stably and at high speed by updating the data of DAC and a register when the error tracking value of the register and the value of a track counter are coincident. CONSTITUTION:A track counter 4 counts down an error track value inputted from a terminal 4a at the time of the track access by a track cross pulse 3 inputted to a terminal 4b and a track counting signal is outputted. A numerical value comparing circuit 8 compares the value of a track counting signal 5 and the value of a register output signal 7, and when they are coincident, a coincident signal MP11 is outputted. The MP11, until a next coincident signal 9 is inputted, performs another processing, the same processing is performed each time the coincident signal is inputted, and since the number of error tracks goes to '0', the generation processing of a reference speed signal can be completed.

IPC: H03G3/30
Filed: 1985-05-20
Abstract: PURPOSE:To decrease the lower limit of a power supply voltage by connecting a collector of the 1st stage transistor (TR) of Darlington connection in a control circuit to an emitter of a TR of the next stage via a resistor and a DC power supply. CONSTITUTION:The collector of the 1st stage TR 5-1 of Darlington connection is connected to the negative side of a DC power supply via a resistor 5-3. When a power supply voltage drops, an output of a high frequency power amplifier 1 is decreased, then a detection voltage obtained by a detection circuit 2 is lowered and the difference with a reference voltage in the DC amplifier 3 is increased. Thus, a base current of TRs 5-3, 5-2 is increased to decrease the difference, then the voltage drop of the part is decreased and a DC voltage fed to the high frequency power amplifier circuit 1 is increased to increase the high frequency power, thereby keeping the power constant. Thus, the lower limit of the power supply voltage is decreased.

Title: Device for treating exhaust gas of nuclear reactor
Inventor: TSUKAMOTO YUICHI
IPC: G21F9/00
Filed: 1987-05-01
Abstract: PURPOSE:To prevent hydrogen recovering power from being affected by a fluctuation in in-leak air quantity even if such fluctuation arises by subjecting the hydrogen in the exhaust gas from a dehumidifier from direct adsorption and recovery by a hydrogen storage alloys. CONSTITUTION:The exhaust gas from a condenser 5 is introduced through an air extractor 9 into a recombiner 11. The water formed therein is removed by a condenser 12 of the exhaust gas system. The oxygen contained in the exhaust gas introduced into the recombiner 11 is generated mainly by the radiation decomposition of water in a furnace core and is decreased to about several % by injection of hydrogen for suppressing stress corrosion cracking. The amt. of the hydrogen to be combined to the oxygen in the recombiner 11 is, therefore, slight and the greater part of the hydrogen injected on the upper stream of a water feed pump 6 to suppress the stress corrosion cracking is subjected to removal of the moisture by the dehumidifier 20 without being consumed in the recombiner 11; following which said hydrogen is sent to a hydrogen recovering column 21. The hydrogen storage alloys is packed in the column 21 and only the hydrogen in the exhaust gas is selectively adsorbed therein. The hydrogen adsorbed in the hydrogen storage alloys is released when the column 21 is heated by a heater 22.

Abstract: PURPOSE:To avoid occurrence of unbalancing in the induction voltage of a plurality of secondary coil windings due to the saturation of the core of a multiple transformer when a device is started and hence an excessive charging of a DC capacitor with a configuration causing a relatively small amount of cost increase. CONSTITUTION:A flywheel diode provided in parallel with a switching element 31 is replaced by a thyristor element 33 whose ON/OFF are controlled by an ignition pulse generated by a pulse generator. When starting the title device, no ignition pulse is applied and the thyristor element 33 is turned off to prevent charge current from flowing to a DC capacitor 2. Then, after the influence of core saturation of the multiple transformer is lost, ignition pulse is applied to the thyristor element to function as a flywheel diode by turning it on for a forward voltage.

Patent JP-H02290146-A (JP)
Title: Frequency generator
Inventor: OBATA SHIGEO
IPC: H02K29/00
Filed: 1989-04-27
Abstract: PURPOSE:To make a signal output uniform both in period and in amplitude by forming the radial extensions of two outgoing lines connected with a magneto coil into the same shape respectively and by letting each radial extension electrically have a phase difference by (360/n)Xm degrees [m=1, 2,...(n-1)]. CONSTITUTION:The beginning and terminating ends of a magneto coil 28 are connected with signal output terminals 70a, 70b via outgoing lines 71a, 71b. In this case, the extended parts of the outgoing lines 71a, 71b are respectively formed into the same shape and electrically have a phase difference by 360 deg. circumferentially to each other. Therefore, a generated voltage is cancelled in the extended parts of the outgoing lines. Moreover, when the phase of the effective generating part 27 of the magneto coil 28 and that of the pole boundary line 124 of a frequency generator(FG) magnetic pole 125 coincide with each other and the generated voltage in the effective generating part is zero, the extended parts are also positioned on the boundary line so that no electricity is not generated in the outgoing line. Therefore, FG signal is not disturbed in its period. Consequently, the variation of the FG signal diminishes both in period and in amplitude.
