IPC: H04N9/09
Filed: 1986-03-06
Abstract: PURPOSE:To constitute a device with a CD image pickup element by setting the vertical transfer frequency of three CCD image pickup elements to a half of one horizontal scanning frequency of a high definition television system and doubling a scanning line by the scanning signal of two CCD image pickup elements out of them. CONSTITUTION:A vertical transfer frequency in a CCD image pickup element is set to a half of a horizontal scanning frequency fH( 33.75kHz) of the high definition television. CCD image pickup elements 161 and 162 light-received with a G color light component are shifted and arranged in the horizontal direction only by a half of a picture element pitch x0 in the horizontal direction mutually, and actually loaded on bimorph piezoelectric elements 171 and 172 to form a phase control means respectively. The G signal read from the CCD image pickup elements 161 and 162 satisfies the interlace of 1035 effective scanning lines, 60Hz and 2:1, which is the standard of the high definition television, by being switched at the frequency of fH with a switch circuit 22.

Title: Driving of gate of power semiconductor switch
Inventor: IIDA KATSUJI
IPC: H02M1/06
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce inductance of a gate lead to shorten the storage time and operation in high frequency by approximately connecting a cathode flange and gate terminal of a cathode post to a gate drive circuit of a gate drive circuit mounting apparatus. SOLUTION: A virtual inductance within the enclosure is reduced to 1/n by providing n gate leads within the enclosure and then dividing a gate current to n currents. Moreover, a gate drive circuit is provided at the area near the external circumference of enclosure to omit the gate lead outside the enclosure. Thereby, inductance of the gate lead inside and outside the enclosure may be reduced as much as possible and a large changing rate of gate current can be attained and the main current can be transferred, during the turn-off period, in the route of anode → gate → gate drive circuit →cathode. Accordingly, the storage time can be reduced to a large extent and the amount of charge can also be reduced, although the peak of the gate current becomes large.

IPC: B62D55/15
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To suppress the deformation of a rolling wheel body even when excessive load acts upon the rolling wheel body. SOLUTION: A reinforcing cylinder 15 is fitted to the inner peripheral side of each cylinder part 14A of a rolling wheel body 14 constituting a lower roller device 8, and the cylinder part 14A is reinforced by the reinforcing cylinder 15 from the inner peripheral side.
