Title: Measurement method for antiphase component of three-phase alternating current
Inventor: TSUNODA TAKANORI
IPC: G01R29/16
Filed: 1992-08-28
Abstract: PURPOSE:To provide a method enabling an antiphase component to be accurately obtained, even when the frequency of three-phase alternating current deviates from the standard frequency. CONSTITUTION:This is a measurement method where current in each phase of three-phase alternating current is selected, data is obtained by sampling the selected current, using a frequency as high as the standard frequency of the three-phase alternating current by an integral number, and then the data is subjected to Fourier conversion for separation into vectors and obtaining an antiphase component. In this case, two antiphase components having a 90-degree sampling phase difference are measured. The antiphase components so obtained are vector added and averaged, thereby obtaining an antiphase component.

Abstract: PURPOSE:To watch three-dimensional television without touching the face directly by fitting spectacles consisting of shutters which can move up and down and use polarizing plates or liquid crystal, etc. CONSTITUTION:A television or movie screen is seen with the left eye through a polarizing plate 11 and the same screen is seen with the right eye through a polarizing plate 12. Then an image corresponding to the left dye and an image corresponding to the right eye are projected on those screens through the vertical polarizing plate 11 and horizontal light shield plate 12 respectively, so those images enter the left eye and right eye separately to enable stereoscopy. Then the shutters which use liquid crystal pass light and cut off the light in other cases and a person who wears the spectacles sees images only in odd-field scanning. This liquid crystal shutters are fitted in front of a normal television screen to project the image of the left dye in the odd field scanning and the image of the right eye in even field scanning. Consequently, the stereoscopy becomes possible with the spectacles consisting of the polarizing plates 11 and 12.

IPC: H03H11/30
Filed: 1994-09-27
Abstract: PURPOSE: To attain high speed signal communication between an input circuit and an output circuit in plural integrated circuits connected to a bus line by suppressing sufficiently a ringing caused by an active element whose electric characteristic is very highly added to the integrated circuits and the bus line. CONSTITUTION: While a change from an ON state to an OFF state of MOS transistors(TRs) 4, 6 is controlled by a delay time of delay circuits 8, 9, since an NMOS TR2 is conductive, two current paths from an output terminal VOUT to a ground GND are in existence. The one is a path for a current flowing from the output terminal to ground via the NMOS TRs 4, 5, 2. Then two potential sets changing timewise by the delay circuits 8, 9 are given to a gate of the NMOSTR3. Ringing caused at the output terminal VOUT is suppressed in two stages by setting the two sets of potential to be a level more than a threshold level of the TR3. The potential difference is adjusted by the gate width of the TRs 2, 4, 5, 6, 7 and the timewise phase difference is controlled by the circuits 8, 9.
