Title: Capacitor group circuit
Inventor: KURIO NOBUHIRO
IPC: H02M7/5387
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To reduce wiring inductance and save overvoltage suppressing circuit such as a snubber circuit by installing film capacitor for absorbing high frequency current ripples, due to switching and an electrolytic capacitor group for suppressing ripples caused by the fundamental frequency. SOLUTION: Overvoltage caused by a wiring inductance Ls and high frequency current ripple caused by switching are absorbed by a film capacitor Cc. Ripples (current ripples) of a DC voltage caused by a fundamental frequency is absorbed by an electrolytic capacitor group Cd. When switching elements Sa-Sf are shorted and broken, stored energy of film capacitor Cc flows into the broken switching elements Sa-Sf. Since this energy is small, spread expansion of the accidence can be prevented. In the case of large storage energy of the electrolytic capacitor group Cd, a current is blocked by a fuse Fs so that fire spread or the like is prevented. As a result, a wiring inductance is reduced and an overvoltage suppressing circuit can be omitted.

Title: Surface acoustic wave high frequency filter
Inventor: KOBAYASHI TAIZO
IPC: H03H9/64
Filed: 1993-09-09
Abstract: PURPOSE:To ensure the sharp frequency characteristic with a frequency difference kept between the resonance and antiresonance points by providing two or more interdigital electrode surface acoustic wave converters in series on a 1st surface acoustic wave resonator. CONSTITUTION:The surface acoustic wave resonators 52-54 are connected in series to a signal line. The resonator 52 contains the interdigital electrode surface acoustic wave converters 8 and 9 connected in series, the resonator 53 contains the interdigital electrode acoustic surface wave converters 10 and 11 connected in series, and the resonator 54 contains the interdigital electrode surface acoustic wave converters 12 and 13 connected in series. The impedances of resonators 52-54 connected in series to the signal line are higher by 4 times than the impedances of the surface acoustic wave resonators 38-40 which are connected in parallel to a signal line. Thus the resonators 52-54 have the sharp frequency characteristics. Therefore the impedance characteristic slope becomes sharp with no shift of resonance and antiresonance points and then the insertion loss is reduced.

Title: Video disk recorder
Inventor: HAYAKAWA YUUJI
IPC: H04N5/85
Filed: 1982-12-20
Abstract: PURPOSE:To avoid the disturbance of a reproduced picture even if the recording is restarted at the middle of a track by making the preceding and next record synchronizing signals accurately coincident to the same revolving angle position of a disk. CONSTITUTION:The output voltage of a comparator 31 for frame synchronous phase is superposed on the voltage of a speed detection signal and then used for the input of a motor driving circuit 12. Then the control is given so as to obtain the coincidence of phase between a frame synchronous reference signal and a revolving position detecting signal. Thus a synchronism detecting signal is obtained from a synchronism detecting circuit 43 when a slight moment elapses from the start of a motor 3. Then switch circuits 21 and 23 are turned off and on respectively. Therefore the stabilized voltage is supplied to the circuit 12 from a stabilized voltage supply circuit 22 in place of the speed detection voltage. As a result, the control disturbance of the motor is not substantially produced despite switching of the circuits 21 and 23.

Title: Magnetic tape system
Inventor: OSADA NOBORU
IPC: G11B20/18
Filed: 1984-10-26
Abstract: PURPOSE:To precisely discriminate an error stripe and a demark stripe and to execute separate processings by nullifying the detecting circuit of the particular pattern that shows a defective stripe for a constant time after a regenerative data decoding circuit starts decoding the data for stripe. CONSTITUTION:When the tape reading starts, a burst detecting circuit 16 transfers a signal S1 to a decoding circuit 12 to indicate a setup for start of decoding, and at the same time transfers the same signal S1 to an error- detection inhibiting circuit 24 to inhibit the demark pattern detecting operation for a period of time t3. When a mark detecting circuit 18 detects a beginning mark BM, the circuit 12 starts decoding the regenerative data, and successively writes its results in a buffer memory 14. When the time t3 has lapsed, the circuit 24 releases the inhibition of detecting operation of a detecting circuit 22. The circuit 22 counts the BM detection signal, and when a prescribed number is reached, transfers a signal S3 to a control circuit 20. The circuit 20 does not transfer the data in a memory 14 to a host device. In case the signal S3 is not inputted after a lapse of time t3, the circuit 20 transfer the data from the memory 14 to the host device, and notifys an error if the error correcting code (ECC) shows defective.

Title: Method and device for oxidation
Inventor: SAITO YUKIMASA
IPC: H01L21/31
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To suppress the formation of a natural oxidized film by housing an object to be treated in a treating furnace preheated to a prescribed temperature and oxidizing the object, by supplying a process gas after the temperature in the furnace is raised to a treating temperature under a reduced pressure. SOLUTION: After the inside of a treating furnace is opened to the atmosphere and heated to a prescribed temperature with a heater, a wafer boat carrying many semiconductor wafers is loaded into the treating furnace. Then the inlet of the furnace is closed with a lid body and the pressure in the furnace is reduced by evacuating the air in the furnace by means of an evacuating system. At the time of loading the wafers into the furnace and performing cycle purging, an inert gas is supplied to the furnace so that no natural oxide film may be formed on the surfaces of the wafers. Then the inside of the furnace is raised to a prescribed treating temperature by controlling the heater in the evacuated state and the evacuating system is switched to a plant exhaust system by means of a change-over valve. Under such a condition, the temperatures of the wafers are stabilized by performing recovery and desired oxidation is performed. After oxidation, the wafer boat is unloaded from the furnace and the wafers are cooled to a transportable temperature.

Title: Acceleration measuring apparatus
Inventor: TAKEUCHI YOSHINORI
IPC: G01P15/03
Filed: 1991-09-05
Abstract: PURPOSE:To obtain a highly reliable acceleration measuring apparatus, which measures acceleration by using light and has small temperature fluctuation, with regard to the acceleration measuring apparatus for detecting the acceleration of a body to be detected. CONSTITUTION:The light emitted from a semiconductor laser 11 is split into two in two directions of a reflecting mirror 13 and a reflecting mirror 14 with a coupler 12. The lights reflected from the reflecting mirrors 13 and 14 are returned to the coupler 12 again, combined here and made to interfere. The interference light is split into two beams with the coupler. One is cast into a photodiode 16, and the intensity of the output of the interference light is converted into the electric signal. When a weight 15 senses acceleration, stress is generated in an optical fiber at a part, which is in contact with the weight 15 and fixed. Thus, the effective refractive index of the optical fiber is changed, and the phase of the light, which is propagating in the optical fiber, is changed. Only one light is subjected to the phase change by the application of the acceleration. Therefore, the state of the interference of both lights is changed. The intensity of the interference light is changed in response to the application of the acceleration. The acceleration of a body to be detected is thereby detected.
