Title: Semiconductor device and its manufacture
Inventor: SHIRATAKE SHIGERU
IPC: H01L21/8234
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the characteristic of a MOS transistor in a peripheral circuit area, by forming the first source/drain areas of a memory circuit area with a single area, and providing a first metallic silicide layer on the surface of the second source/drain areas of the peripheral circuit area. SOLUTION: First source/drain areas 6 and 7 of a first MOS transistor in the memory circuit area are formed by the single impurity area. First metallic silicide layers 21a and 21b are provided for second source/drain areas 22a and 22b of the second MOS transistor in the peripheral circuit area. Since the metallic silicide layer is not formed in the first/drain areas 6 and 7, the deterioration of the characteristic of the memory circuit owing to the occurrence of a crystal defect and the occurrence of junction leak can be avoided. The wiring resistance of the second source/drain areas 22a and 22b can be reduced and junction capacity can be reduced.

Filed: 1987-03-27
Abstract: PURPOSE:To obtain the titled knit and fabric by graphitizing a knit and fabric made of yarns produced by melt spinning a 100% mesophase pitch from petroleum pitch formed as a by-product through thermal catalyst cracking of desulfurized reduced- pressure light oil, followed by making infusible and calcination. CONSTITUTION:First, a petroleum pitch (with initial and final boiling points of 460 deg.C and 560 deg.C, respectively) formed as a by-product through thermal catalytic cracking of desulfurized reduced-pressure light oil is subjected to blowing of a non-oxidative gas to carry out a heating treatment at 380-420 deg.C while stirring. Furthermore, in a non-oxidative gas flow, only the mesophase in the pitch is fused at 300-350 deg.C to effect enlargement followed by separation of the 100% mesophase pitch from the non-mesophase one taking advantage of the difference between their specific gravities followed by purification. This 100% mesophase pitch is brought to melt spinning followed by making infusible in air at 300-340 deg.C and then calcination at 550-1,000 deg.C in an inert gas to produce yarns, which are made into bundles each of which consists of 1,000-10,000 yarns. These bundles are knitted and woven using appropriate machines to form knit and fabric, which are graphitized at 2,000-2,700 deg.C in an inert gas.

Filed: 1978-06-13
Abstract: PURPOSE: To widen a measureable pressure range with pressure resistance increased apparently, by uniforming pressure distribution by providing a doughnut-shaped etching groove to one side of a diaphragm.  
     CONSTITUTION: To the 1st main surface of diaphragm 1 of a N(P)-type Si substrate with integrally-formed support parts 1a and 1b, P(N)-type diffusion resistance 2 is provided and to the 2nd main surface of this diaphragm 1, a doughnut-shaped etching groove is provided. With an uniform-distribution load applied, the strain distribution has its peak at its center and an decrease in strain at its circumference. This part is where diaphragm 1 is thicker. As a result, dispersion of strain is caused, eliminating the peak. Consequently, uniform strain distribution can be obtained by providing a doughnut-shaped etching groove with inner circumferential and outer circumferential surfaces equivalent to two concentric circles, link lines of points where radius-directional and circumference-directional stains become zero.

Title: Display window for luminous body
Inventor: OTA TAKASHI
IPC: G09F13/20
Filed: 1993-03-30
Abstract: PURPOSE:To increase the brightness on the outer periphery of the display window of a luminous body by providing the luminous body with a convex lens with a plane formed as a plane in the central circular region of the convex lens narrower than the light emitting surface region of the luminous body. CONSTITUTION:The central circular region of the convex lens 10a constituting the display window 10 of the luminous body 3, such as LED, has the plane part 10b. The region is formed narrower than the light emitting surface of the luminous body 3. Then, the light passing the central plane of the convex lens 10a advances always rectilinearly in the light emitting surface and the light from the luminous body 3 is visible at 10% through the display window 10 when the lens 10a is viewed from a visual point. Since the central circular region is formed as the plane part 10b, the projecting width in this region is zero and there is a margin in a mounting space. The reduction of the radius of curvature of the curved surface in the outer peripheral part is, thereupon, possible and, therefore, the light entering to the outer peripheral part of the lens from the visual point is refracted more to the central axis side of the luminous body. Consequently, the light form the luminous body 3 is more condensed by the convex lens 10a and the entire part of the display window 10 is brightened.

IPC: F16K47/02
Filed: 1987-03-25
Abstract: PURPOSE:To absorb and mitigate a water hammering phenomenon effectively, by interconnecting a valve box inner part and its void at the more upstream side than a primary seat with each other, and installing a pressure receiving surface deformable in adjoining a void proximate to a secondary side seat. CONSTITUTION:A ball type valve disc 2 made up of piercing a water passing port 2' in the center is made to get closer to two seats 4 and 5 at both primary and secondary sides, and a pressure inlet passage 3 is piercingly installed in the valve disc side center at the primary side. When a ball valve is suddenly closed, the fluid passed through the water passing port 2' and the pressure inlet passage 3 at a side face of the valve disc 2 is intercepted in and around the secondary seat 5. With this interception, internal pressure in a valve box void 1d inceases and simultaneously a pressure receiving surface 7a goes up against resilience of a cushioning material 7b, and capacity in the valve box void 1d increases according to the lifting value. Accordingly, pressure inside the valve box void 1d is absorbed and mitigated.
