Title: Mos semiconductor device
Inventor: ARAI TOSHIHIRO
IPC: H01L29/78
Filed: 1995-05-25
Abstract: PURPOSE: To avoid the field concentration in an angle part of a cell structure FET wherein the second conductivity type channel region with a well region with high impurity concentration formed therein, the first conductivity type source region formed on the surface region of the first conductivity type semiconductor substrate, furthermore, a MOS structure formed on the surface for increasing the breakdown strength. CONSTITUTION: A p-channel regions 3 having a P<+> well region 2 and an n source region 4 has a striped shape to connect the end parts with each other removing any protrusions excluding in the outermost peripheries. Thus, the breakdown strength can be increased since the conventional field concentration in the protrusions are removed. Accordingly, a crystal of lower specific resistance to the same rated breakdown strength can be used thereby enabling the on- resistance to be lowered.

Abstract: PURPOSE:To maintain the radial gap of vane constant by fitting an eccentric bearing into an eccentric drive bearing groove in a crank shaft while placing a resilient member in the eccentric drive bearing groove and energizing the eccentric bearing outwardly at all times. CONSTITUTION:An eccentric drive bearing groove 10 is formed at the upper section of a crank shaft 8 so as to contain an eccentric bearing 11 fittable to the drive shaft 3 of a spiral vane part 2. A coil spring 12 for energizing the eccentric bearing 11 radially outward from the crank shaft 8 is arranged in the eccentric drive bearing groove 10. The crossing angle between the longitudinal direction of the eccentric drive bearing groove 10 and a combination force F of gas compression force fg and centrifugal force fc is set higher than 90 deg., where the combination force F functions continuously such that the turning radii of the eccentric bearing 11 and the spiral vane part 2 are reduced. Consequently, the eccentric bearing 11 is held at a position where the combination force F and the force of the coil spring 12 are balanced thereby the radial gap of the spiral vane part 2 is maintained constant.

IPC: G11B11/10
Filed: 1994-05-16
Abstract: PURPOSE:To obtain a driving circuit for a magnetic head which can improve a write speed to a magneto-optic disc. CONSTITUTION:Base earth amplifiers B1 and B2 are connected at an output side of a differential switch SW, and a coil of a magnetic head is connected at an output side of the amplifiers B1 and B2.
