Title: Manufacture of semiconductor device
Inventor: YANO YUISUKE
IPC: H01L27/092
Filed: 1994-01-24
Abstract: PURPOSE:To improve breakdown voltage by forming silicon nitride for oxidation prevention only in a n-channel transistor formation region, and forming a gate bird's beak only in the n-channel transistor. CONSTITUTION:Heat treatment is performed, and a mask oxide film 1 is formed and simultaneously a gate bird's beak 2 is formed at the bottom of the edge of a gate electrode 9. In this oxidation process the gate bird's beak 2 is formed only in the gate oxide film 10 on the edge of the gate electrode formed on a P-type well 15. On the other hand, a gate electrode formed on a N-type well 16 has silicon nitride 8 formed at upper surface of electrode. Therefore, no mask oxide film 1 or gate bird's beak is formed in a p-channel transistor formation region, and thus threshold voltage will not be increased. This males possible the improvement of breakdown voltage.

Filed: 1979-01-26
Abstract: PURPOSE:To reduce the time required for turning around a pressed work without changing the position of the work before and after the turning-around, by rotating simultaneously a pair of clamps of a turn-around section, which clip a work, around the center of the direction for feeding work. CONSTITUTION:A work 2 is placed on the supporting member 4a, 4a' of clamps 4, 4' by the attracting arm of a pressed-work-drawing off unit. Air cylinders 20, 20' for transferring driving means are actuated in order to clip the work 2 with clamps 4, 4'. Then the air cylinders are operated so as to rotate levers 33, 34 clockwise around a driving shaft 36. Rotation of the levers 33, 34 causes the clockwise rotation of pinions 16, 16' through racks. Hence clamp holders 17, 17' and the clamps 4, 4' are rotated simultaneously through 180 deg., thereby turning around the work 2. Then the work 2 is released from the clamps 4, 4', which clip the work 2, by the rise of the work-supporting member 3 and the jig 41 to the position of a two-dots chain line, whereby the work 2 is placed on the jig 41 and is carried out.

Title: Choke coil
Inventor: KAWAHARA TAKESHI
IPC: H01F37/00
Filed: 1986-01-16
Abstract: PURPOSE:To obtain the choke coil, the inductance of which increases extremely with the decrease of DC superpositional current as compared with the inductance when the DC superpositional current is high, by a method wherein a gap is formed on the inner side of an annular wound core. CONSTITUTION:A winding 2 is wound around an annular wound core 1, and a gap 3 cut in radial direction is formed on the inner circumferential part of the core 1. To be more precise, the annular wound core 1 is composed of a gapped annular wound core part 1a and a gapless annular wound core part 1b. As a result, the choke coil having the characteristics, wherein the inductance when the non-magnetic saturation DC superpositional current value is less than I1 or below increases to an extreme when compared with the inductance corresponding to the magnetic saturated DC superpositional current value I2 from I1 with which the gapless annular wound core part 1b is magnetically saturated, can be obtained. Also, as the leakage magnetic flux, which is generated by the DC superpositional current running to the choke coil, is generated in the inside only of the choke coil, because a closed magnetic path is formed by the gapless annular wound core part 1b on the outer circumferential part of the annular wound core 1, and the leakage magnetic flux is not generated on the outside of the choke coil.
