Title: Current type converter having reactive power compensating function
Inventor: SHIMA KIYOYA
IPC: G05F1/70
Filed: 1986-10-29
Abstract: PURPOSE:To decrease the power supply capacity and the higher harmonic wave current of the titled converter by using a function to compensate the instantaneous reactive power concurrently with feedback control of the DC output voltage. CONSTITUTION:The 3-phase AC power supply voltages eu-ew are applied to a converter main circuit Cn consisting of six transistors and an output DC current I is supplied to a load Ld via a DC reactor L. A current control circuit Ic compares the DC current I detected by a current transformer CTd with a current command Is to calculate a DC voltage command Ids to apply it to a computing element C. Here the DC current I, a reactive power command qs and the inter-line effective value Ea of the power supply voltage are also applied to the element C for calculation of a flow angle (gamma) and a phase angle (alpha) to apply them to a pulse generating circuit Pc. Thus it is possible to compensate the instantaneous reactive power of another device up to its limit capability while the output current I is controlled to a prescribed level.

Title: Mpeg video decoder
Inventor: KOYAMA MOTOAKI
IPC: H04N19/44
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To decrease a capacity of a memory used for reconfiguring and displaying a B-Picture in compliance with the MPEG(moving picture experts group) to 16 Mbits or below. SOLUTION: A bit stream once stored in an input bit stream buffer by an input control section is decoded by a VLD(variable length decoder), inversely quantized by an IQ, subjected to inverse discrete cosine transform by an IDCT (inverse discrete cosine transform). The P and B-Pictures in the processed stream are reconfigured by a frame buffer and an MC and the result is displayed via a display macro block buffer. In this case, since the B-Pictures are not buffered by one frame, data deficient in reconfiguring the B-Pictures are obtained from data read from the stream buffer by the input control section and decoded by the VLD at high speed and displayed through the reconfiguration. Part of the frame buffer is used for displaying the P and B-Pictures so as to decrease the capacity of the frame buffer and the display macro block buffer to 16 Mbits or below in the case of the PAL stream.

Title: Method for driving electro-optical element
Inventor: SUGIYAMA ATSUSHI
IPC: G02F1/133
Filed: 1987-10-12
Abstract: PURPOSE:To shorten the erasing time by not applying about '0' volt before applying a pulse voltage in an erasion period at the time of executing the erasion of the contents of an electro-optical element by applying both the pulse voltage and about '0' volt. CONSTITUTION:In a cell having a hysteresis in a high twist state exceeding 90 deg., the erasing time becomes necessary additionally by about a pre-erasing time irrespective of the length of the pre-erasing time. At the time of executing a high pulse erasion, the state of a liquid crystal molecule in the pre-erasion period does not have a relation so much to an erasion, and since the pre-erasion is not performed, the erasion period can be shortened at least by a time portion of the pre-erasion. Also, as the case may be, the extension of the erasing time can be prevented by the pre-erasion. Accordingly, at the time of erasing a high voltage pulse, the erasion period 6.1 can be shortened by prescribing a suitable voltage applying sequence.
