IPC: H01T15/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To provide an ignition coil which is easy to draw an input/output line to a transformer with improved energy efficiency. SOLUTION: A contact part between an arm part 22 of an auxiliary core 12 and a side core 13 is fitted to all slit edge parts or put with a uniform space from each side of all the slit part. As a result, an inner drawing line from a transformer part 10 can be easily taken through a gap between the arm parts 22, so that connecting face of the arm part 22 joined magnetically to the side core 13 is located near to an edge part of the slit part 14. At the same time, strong magnetic flux at a peripheral edge part is dispersed at a contact face between the side core 13 and the arm part 22 to prevent magnetic saturation at this part.

Filed: 1982-04-21
Abstract: PURPOSE:To prevent the generation of a glitch and higher harmonic components, by providing level interpolating circuits which have switched capacitors to the gates of MOSFETs which have weight corresponding to an input digital signal. CONSTITUTION:The level interpolating circuits are provided to the gates of the MOSFETs Q00-Q0n for preventing the generation of the glitch and highr harmonic components of a D/A convertion output voltage VOUT substantially. Those level interpolating circuits are constituted by utilizing switched capacitor circuits. The input digial signal is integrated by the switched capacitors into a fine staircase digital signal, which is supplied to the gates of the FETs Q00-Q0n. Those FETs Q00-Q0n receiving the level-interpolated digital signal vary in drain currents I0'-2<n>I0' gently. Consequently, a D/A conversion output voltage VOUT' also varies gently to prevent the generation of the glitch and higher harmonic components substantially.

Title: Laser beam cutting method in continuous hot rolling
Inventor: MINAMIDA KATSUHIRO
IPC: B23K26/21
Filed: 1994-04-04
Abstract: PURPOSE:To shorten the time of process and to improve the accuracy of press- fixing by cutting the p of a rolled stock welded with a laser beam by laser beam cutting with oxygen and cutting the part in pressurized contact with a roll by laser beam cutting with argon or nitrogen. CONSTITUTION:The abutting part of the rolled stock is composed of laser beam welding regions W1, W3 and press-contact region W2. In the laser beam welding region W1, laser beam cutting is executed at high speed by jetting oxygen. And, by instantly switching oxygen to argon or nitrogen, the press- contact region W2 is cut by the laser beam. Consequently, the press-contact region W2 is not oxidized, so joining strength by press-contact is excellent. Next, by switching argon or nitrogen to oxygen, the laser beam welding region W3 is cut at high speed by the laser beam. After cutting, the rolled stocks are brought into press-contact and the laser beam welding regions W1, W3 are welded by the laser beam. In this way, productivity is improved.
