Title: Seal member for cowl top cover
Inventor: SAKAI KAZUHIRO
IPC: B62D25/08
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a seal member facile in mounting it on a cowl top cover body, having no looseness between the body and the seal member, capable of completely blocking rain water and dust from entering between the body and the seal member and providing excellent external appearance. SOLUTION: A seal member 12, which equipped with a catch 14 to a cowl top cover body 11 and a lip 17 composed of a soft material formed integrally on one end of the catch 14, includes an extended portion 15 extending from the other end of the catch 14 and, because the extended portion 15 elastically contacts with the catch end with the seal member 12 fitted to the cowl top cover body 11, play between the cowl top cover body 11 and the seal member 12 is sealed up and play can be prevented and entry of rain water and dust can be completed blocked up. Because the whole top of the catch 14 is covered up with a cover 18 made of the same soft material as the lip 17, the boundary line of the catch 14 and the lip, which are of different material, does not show and therefore the external appearance is improved.

Title: Field effect transistor and manufacture thereof
Inventor: TERADA TOSHIYUKI
IPC: H01L29/812
Filed: 1985-03-28
Abstract: PURPOSE:To keep the distribution of an electric field at a pinchoff point at the same value as that in a long-gate structure and to solve the problem of deterioration in characteristics caused by miniaturization, by partially forming a second conducting type layer at the lower part of the end part of an operation layer at the drain side, which determines the pinchoff of an FET. CONSTITUTION:A p-type layer 14 is formed in contact with an operating layer 12 at the lower part of the operating layer 12 at the end part on the drain side, which determines pinchoff. The lower part of the operating layer 12 becomes a depletion region by a junction potential between the p-type layer 14 and the operating layer 12. Thus, the effect that the operating layer becomes substantially thin is obtained, and normally OFF type characteristics are obtained. In an MOSFET having the conventional structure, in which ions are implanted at the same acceleration energy of 50keV, the same threshold voltage is obtained in the operating layer. In comparison with said conventional MESFET, the operating layer in this device is substantially thin and has high concentration. As a result, the electric-field distribution on the drain side, which determines pinchoff, becomes the same as that in the case of a long gate. A part of the operating layer other than the region on the drain side indicates normally ON characteristics. Therefore, a current driving capability becomes large when compared with the same gate length.
