Title: A gate array with transistor in wiring region
Inventor: KUBOSAWA HAJIME
IPC: H01L27/118
Filed: 1988-02-09
Granted: 1990-10-29
Abstract: Parallel columns (41) of basic cells (44) are formed on a semiconductor substrate and sepd. by interconnection regions (42) primarily for intercolumn wiring purposes. In one or more predetermined interconnection regions (42S) a specific cell (47X) is buried with an interconnection (48) to a neighbouring basic cell (44X), to constitute a bus driver. The specfic cell (47X) comprises p-channel and n-channel transistors (P3,N3) constituted by gate electrodes (51,52) and diffusion regions (53,54) extending parallel to the basic cell columns (41), so that the channel width (3W) can be three times that of transistors in a conventional gate array having the same channel length (L).

Title: Duct pressure powered air volume controller
Inventor: TULOWIECKI DAVID A
IPC: F24F11/04
Filed: 1988-04-28
Granted: 1990-07-31
Abstract: The controller is connected to a duct pressure powered air terminal unit. A pressure drop is sensed in the terminal unit and to a specific air flow in the unit. The sensed pressure drop is communciated to the controller as two pressure signals. The controller bleeds one pressure signal to control the inflation of a bag or bellows and to modulate the terminal unit to maintain a constant volume air flow through the unit as duct static pressure varies.  The controller bleeds the second pressure signal to maintain at least a minimum flow through the unit.

IPC: H04N19/00
Filed: 1991-01-22
Granted: 1994-01-21
Abstract: The invention improves the problems that degradation of the picture quality is more serious rather than the noise reduction effect in the edge of the picture even if the channel noise of the low band signal component can be reduced through the noise reducer by using correlation between the picture elements, and that it is waste of the quantity of transmission information that the high band image signal component usually has narrow distribution of its level. Adaptive modulation is applied to the high band image signal and low band image signal respectively and the high band image signal is transmitted in 6-bit pattern so that the channel noise and the quantity of the transmission information are reduced.

Abstract: P형 반도체기판(1)의 상면상에 n-에피타키셜층(4)을 형성한다. 
     P형 반도체기판(1)과 n-에피타키셜층(4)에 걸쳐있는 영역에 이온주입에 의하여 P+매몰층(20)을 형성한다. P+매몰층(20)의 상층에는 이온주입에 의하여 P+채널스톱층을 형성한다. 
     P+채널스톱층의 상층으로부터 n-에피타키셜층의 상면에 걸쳐 P웰을 형성한다. 
     이 P웰(22)에는 n채널 MOS형 전계효과 트랜지스터(200)가 형성된다. 
     이와 같은 구조로 인접소자로부터 소자를 신뢰성 있게 분리할 수 있다.

Abstract: forming an in-situ phosphorus doped amorphous silicone thin film(3) by LPCVD using Si2H6 gas and PH3 gas on a silicone substrate(1) which a word line and bit line are formed on; changing the amorphous silicone thin film(3) into a polysilicone thin film(3a) whose grain size is increased by thermal processing in the atmosphere of an inert gas; forming a W-silicide thin film(4) on the polysilicone thin film(3a) and thermal processing in the temperature of 800-100 deg.C. to extract silicone contained in the W-silicide thin film(4) to the interface between the polysilicone thin film(3a) and the W-silicide thin film(4); and forming a word line and bit line(6) by patterning the W-silicide thin film(4) and the polysilicone thin film(3a) in sequence.
