Title: Estimation method for intrinsic frequency of power system
Inventor: KUNIHIRO NAOKI
IPC: H02H3/52
Filed: 1992-08-26
Abstract: PURPOSE:To estimate an intrinsic frequency in power-feeding system with improved accuracy in order to specify a load of a rectifier that causes a higher harmonic. CONSTITUTION:A fundamental harmonic is removed from charged current waveform data D1 that is measured so that only higher harmonics data D2 can be obtained (steps 101 and 102), and time t1 at a maximum amplitude of a commutation oscillation factor is selected (step 103). Also, data D3 is obtained by taking out a waveform from the time t1 to a moment when a term (T/N), i.e., a period (T) divided by a commutation phase number (N), is completed (step 104). Then, frequency analysis in Fourier series expansion is carried out so that a frequency factor at any order is not stressed, and a local-peak interference between commutating oscillations is prevented. Consequently, a local-peak frequency as an estimation value of a natural frequency is obtained easily with accuracy.

Filed: 1993-09-13
Abstract: PURPOSE:To set locks which are different by threads by detecting access which violates a lock as to access to shared data by using a shared data identifier. CONSTITUTION:In a process, plural threads perform transaction processes in parallel. In the transaction processes, the shared data in a secondary storage are mapped in a thread characteristic area in a virtual space, and referred to and updated to perform exclusive control by a two-phase lock.

IPC: H03H17/00
Filed: 1992-08-26
Abstract: PURPOSE:To improve the accuracy of canceling the incoming noise to a receiver by setting the transmission function of a filter. CONSTITUTION:The output of a microphone 14 for collecting ambient noises disposed near a receiver (speaker) 13 is impressed via a filter 15 (transmission function Tf) to an adder 17 which adds this output to a received sound signal R. The added output thereof is supplied to the receiver 13. The transmission function Tf of the filter is so set as to attain Tf+kT12 0 (T12 is the transmission function from the front surface of the microphone 14 to the sound radiation space 9 of the receiver 13, k is an amplitude coefft.), by which the noise components in the sound radiating space are canceled. The filter of an adaptive type is used. The Tf may be set at the time of non-call and may be fixed at this set value at the time of call. The sound pressure P2 of the sound radiation space is detected by disposing the second microphone 21 near the receiver 13 and the filter 15 is controlled by a control circuit 22 as to minimize the ratio ¦V2/V1¦ of the detected output V2 to the output V1 of the microphone 14.

Title: Transmission
Inventor: SEKI HIROBUMI
IPC: F16H3/72
Filed: 1985-10-11
Abstract: PURPOSE:To produce the large speed ratio of an input shaft to an output shaft by meshing the input and output gears of a transmission with epicyclic gears to drive an input shaft, and thereby causing a supporting frame for the epicyclic gears to rotate during deceleration or acceleration. CONSTITUTION:An input gear 5 fixed to an input shaft 3 and an output gear 6 fixed to an output shaft 4 are meshed with an epicyclic gear 10, and a supporting frame 8 to support the epicyclic gear 10 is concentrically and rotatably fixed to the output shaft 4. When the inlet shaft 3 rotates in an arrow direction, an interlocking shaft 11 rotates in the arrow direction to make the supporting frame 8 rotate in the same direction as the inlet shaft 3. In this case, when the number of teeth of gears 12, 17 is less than that of gears 13, 16, the supporting frame 8 rotates more slowly than the input shaft 3 in its same direction. When the reduction ratio formed by the number of teeth of the above gears is 1/2, the output shaft 4 stops, and when the said ratio is less than 1/2, the output shaft 4 rotates reversely. Thus, when the supporting frame 8 rotates more slowly than the input shaft 3, the output shaft 4 rotates still more slowly than the input shaft 3. Consequently the large reduction ratio can be produced.

Title: Inverter type x-ray device
Inventor: SAKAMOTO KAZUHIKO
IPC: H05G1/20
Filed: 1994-08-30
Abstract: PURPOSE: To restrain surge voltage to prevent the rupture of a switch by connecting between a DC power source and an inverter by means of a laminated plate to reduce the inductance of a wiring. CONSTITUTION: A laminated plate 6 is formed by laminating the first layer of the conductive plate 61 of a positive electrode, the second layer of the conductive plate 62 of a negative electrode, and the third layer formed of the conductive plate 63 of the output of the positive electrode and the conductive plate 64 of the output of the negative electrode; to nip first and second insulators 65 and 66 between these respective layers. Consequently, electric currents Ip and In flowing to an inverter from a DC power source flow to an output terminal OUT from an input terminal IN on the plates, but since uniformity is absent in the direction of a flow, thereby also generated magnetic flux has no uniform direction.  In the magnetic flux genetated in the same plane on the plates, neighboring magnetic flux is canceled, and uncanceled magnetic flux becomes difficult to be interfered because of a distance to narrow magnetic fields f1 and f2 generated in the whole plates. As a result, wiring inductance can be sharply reduced to restrain surge voltage to prevent the rupture of a switch.
