Title: Liquid crystal display device
Inventor: OBATA MASAO
IPC: G02B6/00
Filed: 1991-07-19
Abstract: PURPOSE:To increase the grade of a display by making incident efficiency on the light incident end surface of a liquid crystal device excellent and preventing a void phenomenon. CONSTITUTION:The light incident end surface 11a of a light transmission plate 11 is formed in the shape of a concentric arc with a tube light source 12, and the reflection of light is reduced. On the front surface end part of the light transmission plate 11, a front part reflecting film 14 is provided on a region (alpha) where the light from the light source 12 travels straight without being totally reflected on the front surface of the light transmission plate 11, and direct light from the tube light source 12 is reflected backward. A side part reflecting film 18 is directly formed on the periphery of the tube light source 12, heat from the tube light source 12 is radiated from the side of the side part reflecting film 18, and the local rising of a temp. on the light incident surface is relaxed. Therefore, the local rising of the temp. in the vicinity of the light source can be reduced.

Title: Apparatus for removing reaction by-product
Inventor: MITSUI AKIRA
IPC: B01D45/08
Filed: 1988-07-19
Abstract: PURPOSE:To improve removing efficiency for reaction by-product without increasing washing frequency of a trap contg. said reaction by-products by using a shape memory alloy for a material of a fin for removing the reaction by- products contained in a trap. CONSTITUTION:The temp. of a fin 1 elevates to about 50-100 deg.C when there is a gas stream, and the fin 1 constituted of a shape memory alloy becomes almost a flat plate shape. Therefore, the fin has a flat plate shape and catches reaction by-products on its surface when a waste gas (at high temp.) flows. But, the temp. in a trap descends gradually after the completion of a reaction and completion of a purge stage wherein a vacuum valve is closed, and the shape of the fin changes from flat shape to bent shape. Reaction by-products sticking to the fin 1 contract by the repetition of said operations, and are stripped off finally from the fin 1, and fall down into the bottom of the trap.

Title: Optical filter
Inventor: NISHIDA MINORU
IPC: H04N5/65
Filed: 1984-08-29
Abstract: PURPOSE:To observe a large-sized display device from a wide-angle range and to obtain the best view in a slanting direction by dispersing a light diffusing material in a plastic material and forming a light projection side in a shape of a plane prism, and slanting the main diffusion direction of transmitted light by some angle. CONSTITUTION:Light from a light source 3 is diffused by the diffusing material 2 dispersed in the filter 1, and refracted and transmitted through the plane prism 11. Projection light is refracted in a constant direction on the whole, and consequently the direction of the main diffused light, i.e. intensity peak of the projection light deviates from a vertical light to the filter in a specific direction. For example, aluminum hydroxide is dispersed in a vinyl chloride resin compound and a filter substrate in the form of an about 0.5mm thickness sheet is pressed with a die having a saw-tooth cross section with 30mu pitch P and a 65 deg. prism vertical angle to obtain the optical filter.

Abstract: PURPOSE:To increase a crown controlling capacity and to reduce the necessary shifting amount by performing a rolling by giving the initial crown having a different crown control capacity via an optional position (two points) in the axial direction in case of relatively moving the upper and lower work roll couple in the axial direction. CONSTITUTION:The initial crown in about the same shape is given to the upper work roll 2 and lower work roll 3 respectively so as to cross at three places respectively with the straight XUL, XLU which are of point symmetry and parallel to the roll shaft, passing origins CU, CL, and the crown of the material 1 to be rolled is controlled by relatively moving in the axial direction the work rolls 2, 3 each other based on the rolling conditions varying according to the change in the width, thickness, temp., rolling load, etc. of the material 1 to be rolled. Since the material 1 to be rolled is rolled by giving the initial crown having different crown controlling capacity via optional position in the width direction (two points) with the point symmetrical origin as the center to this work rolls 2, 3, the crown controllability is improved and shifting amount is reduced as well.

Title: Can body
Inventor: SUGAI KINICHI
IPC: B21D51/44
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To contrive a display at low cost even for a complicated shape and to make it easily identifiable even with waterdrops attached by providing a roughened surface for a data display by means of crimping on a part of the cover or bottom of a can. SOLUTION: The top part 12 of a can cover A is provided with a mark M by crimping in the part not superimposing on a pull tab 16 and an opening piece 11. The mark M is formed by pressing, on the top part 12 of the can cover A, a metallic die incorporating the mark M which is a roughened surface with a number of minute projected and recessed parts. Thus, the can body 1 is marked with a display with high precision even if it is a complicated or minute shape like the mark M; and also the equipment cost is low because the crimping is done by one metallic die arranged on one part of the surface of the can cover A. Moreover, the crimping part of the surface being a roughened surface forming an irregular reflection, the mark M is clearly discriminated against the glossy surface of the can cover A, providing a high identifiableness.

Title: Semiconductor memory device
Inventor: MAEDA SATORU
IPC: H01L21/74
Filed: 1983-09-30
Abstract: PURPOSE:To prevent a latch-up phenomenon, and to inhibit a soft error by forming an element region as a memory cell section so as to be directly brought into contact with a substrate and interposing an insulating layer in an element region constituting a complementary type MOS transistor as a peripheral circuit. CONSTITUTION:When alpha-rays are projected into a p type element region 20 for a memory cell section and electrons are generated, generated electrons are sucked into an n type silicon substrate 11 by the potential difference of a p-n junction and a soft error is inhibited because the p type element region 20 is in contact with the substrate 11 directly. Since thin oxide layers 151, 152 are interposed on the interfaces among n type and p type element regions 13, 14, in which p channel and n channel MOS transistors are formed, and the silicon substrate 11, the formation of parasitic bipolar transistors is obstructed, and a peripheral circuit for a CMOS, through which a latch-up phenomenon is not generated and which has excellent element characteristics, can be obtained.

Title: Ultra-high pressure electric-discharge lamp
Inventor: YANO YOSHIHISA
IPC: H01J61/36
Filed: 1981-11-11
Abstract: PURPOSE:To obtain a small ultra-high pressure electric-discharge lamp, which has an excellent shock-resistant performance and a high luminance characteristic, by forming a straight tubular bulb from a light-transmitting alumina such as monocrystal sapphire, fusing electrode-supporting bases to both ends of the bulb through joint tubes, and attaching an exhaust tube to one of the bases. CONSTITUTION:Sice an exhaust tube 19 is attached to one of bases 14, a bulb 11 is not required to have any spherical part used for installing the exhaust tube 19. In addition, since the bulb 11 is made of monocrystal sapphire, the physical properties, especially the strength, of the bulb 11 are more excellent than those of quartz glass. Therefore, the bulb 11 is not broken by sufficiently resisting the internal pressure (over several ten atmospheric pressures) of the bulb 11 during lighting, without any need of providing the bulb 11 with a spherical part. As a result, the bulb 11 can safely have a straight shape without any need of a spherical part, and the bulb 11 doesn't touch electrodes (an anode 15 and a cathode 16) since the electrodes are supported by bases 13 and 14. Besides, the shock-resistant performance of an ultra-high pressure electric-discharge lamp is remarkably increased due to the fact that the lamp is not provided with any pinch seal part.
