Title: Field-effect transistor
Inventor: OKUDA YOSHIMITSU
IPC: H01L29/78
Filed: 1988-06-25
Abstract: PURPOSE:To reduce an occupied area by a thin diffusion layer of an LLD structure on a semiconductor substrate and allow a groove to be vertically formed in a self-aligning manner with respect to the gate electrode and the oxide film by forming the thin diffusion layer of LDD structure on the sidewall of the groove. CONSTITUTION:A gate oxide film is formed after arranging an element isolation layer 2 on a P-type silicon substrate 1, and a polysilicon gate electrode 3 is formed on this gate oxide film. Then, a groove 4 is formed on the silicon substrate, and a heavily doped N-type diffusion layer 5 is arranged by ion- implantation into the bottom of the groove. Ion-implantation is then performed at an angle to the sidewall of the groove to thereby form a thin N-type diffusion layer 6. The arrangement of this thin diffusion layer 6 perpendicular to the surface of the substrate contributes to reducing the occupancy of the transistor, thereby allowing the degree of integration to be increased. Since there is no need for going through a process of forming a spacer on the sidewall of the gate polysilicon, the manufacturing process is simplified.

Title: Level switch for fuel cell cooling water system
Inventor: MIYAMA HARUMI
IPC: H01M8/04
Filed: 1991-06-28
Abstract: PURPOSE:To enhance accuracy of detection of a water level by restraining a wave of cooling water inside a steam separator. CONSTITUTION:A wave breaker 21 inhibits propagation of a wave generated on a water level of cooling water 9 due to flowing-in of a two-phase flow 9B from an inlet 5A. A level switch 7A accurately detects the water level corresponding to an average water level. Accordingly, the switch 7A detects with high accuracy supply of steam 8 to a fuel reformer and a decrease in water level caused by discharge of blow water, to thus supply shortage water 9 and control a variation range of the water level from a lower limit L to an upper limit H. Improved detection accuracy can reduce a difference between the water levels H, L of the switch 7A. Consequently, the water level of a steam separator 5 can be lowered so that miniaturization can be achieved, a water treatment system can be miniaturized, and as a result, a device can be miniaturized as a whole.
