Patent JP-H01105579-A (JP)
Title: Insulated gate type bipolar transistor
Inventor: YAMANAKA KAZUO
IPC: H01L29/68
Filed: 1987-10-19
Abstract: PURPOSE:To diffuse the passage of a hole current and to enhance a latchup threshold current by forming an emitter region formed in a cell in a shape that a channel formed adjacent does not become a closed circular shape. CONSTITUTION:An N<+> type region 11 is divided into two trapezoidal regions. An electron current Ie flows through a channel 17 generated under a gate electrode between the region 11 and an N<-> type region 14, but a hole current mainly flows as Ih1, Ih2, and the Ih3 flowing under the region 11 becomes a small value. This distribution is performed since the current amount is inversely proportional to the resistance, the ratio of the current relative to latchup to the hole current is reduced. As a result, a threshold current becomes larger value.

Abstract: PURPOSE:To generate a very fine X-ray beam by using two kinds of materials having different absorption coefficients, and coating an absorption layer made of the material having a larger X-ray absorption coefficient on both faces of a transmission layer made of the material having a smaller X-ray absorption coefficient. CONSTITUTION:Tungsten is deposited to the thickness of 0.1mum, for example, on the surface of a base 9 made of a gallium-arsenic alloy rarely transmitting X-rays, then carbon is deposited to the thickness of 0.1mum on the surface, and tungsten is again deposited to the thickness of 1mum on the surface to manufacture a multi-layer film X-ray slit. Tungsten is a heavy metal having a large X-ray absorption coefficient and rarely transmitting X-rays and forms absorption layers 2, 3. Carbon transmits X-rays well, and it is a material having a small absorption coefficient of X-rays and forms a transmission layer 1. When incident X-rays 7 are radiated, the X-rays 7 are almost absorbed by the absorption layers 2, 3, the X-rays 7 are transmitted by the transmission layer 1, and a fine X-ray beam of 0. lmum is radiated to an object as outgoing X-rays 8. The incident X-rays at an incident angle ALPHA within the incident X-rays 7 pass through the transmission layer 1 on the boundary face between the transmission layer 1 and the absorption layers 2, 3.

Title: Video signal transmission system in broad-band transmission
Inventor: KOIKE KATSUYUKI
IPC: H04J1/00
Filed: 1989-10-09
Abstract: PURPOSE:To improve the picture quality of video image by modulating a luminance signal and a chrominance signal with a carrier apart by at least a base band of the luminance signal respectively, sending the resulting signals and demodulating the luminance signal and the chrominance signal at each terminal equipment uniquely respectively. CONSTITUTION:A luminance signal Sy and a chrominance signal Sc are modulated by respective carriers so that each band is not overlapped and the modulated signals are sent. Since no limit exists in a band width per channel in a broad- band transmission line, the luminance signal Sy and the chrominance signal Sc are modulated with entirely independent carriers and sent. Then the signals are demodulated at terminal equipments at respective carriers to obtain base band luminance signal and chrominance signal. Since the band of the luminance signal Sy and the chrominance signal Sc is not overlapped, the picture quality of the sent video image is improved.
