Title: Sheet light source device and liquid crystal display using it
Inventor: ITO ATSUSHI
IPC: F21Y103/00
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a sheet light source device, which has a high impact resistance, can be produced at low cost, and also can be prevented from the generation of non- uniform brightness. SOLUTION: A side light type sheet light source device includes a light guide plate made of a transparent material; at least one rod-shaped light source disposed adjacent to a light-incident surface which is a side section of the light guide plate; a tubular reflective member covering a portion of the rod-shaped light source other than a face of the light source opposite to the light guide plate; a planar reflective member disposed adjacent a position opposite to a lower surface of the light guide plate; and a protecting/maintaining member receiving the light guide plate, the light source and the two reflective members. A portion of a side of the light guide plate on which the rod-shaped light source is disposed is in contact with the protecting/maintaining member side to protect/maintain the light guide plate. Thus, the protecting/maintaining member has an end formed thereon.  Also, in the end of the protecting/maintaining member, a space between the light guide plate and a protecting/maintaining member is narrower than a space between an opened end of the tubular reflective member and the light guide plate.

Title: Coil
Inventor: YOSHIMURA FUMIO
IPC: H01F27/32
Filed: 1987-11-30
Abstract: PURPOSE:To cause a layer short rapidly which occurs near the end of the life of a coil, and to cause the breaking of the coil, for increasing the safety factor, by filling up the gaps among conductor segments of the coil with wax having a lower melting point than that of the insulating film of the conductor. CONSTITUTION:A conductor 2 is coiled in a ring winding space around a bobbin 1, and a low melting point (approximately 60-90 deg.C) wax 3 is filled up in the gaps. The insulating film 22 of the conductor 2 is formed with a thermoplastic resin (e.g., polyurethane) whose melting point is higher than that of the wax 3, or with any kind of materials such as an oil enamel. If a layer short happens by the deterioration of the insulating film 22 of the conductor 2, and the conductor segments 21 touch each other directly pressing each other. As a result, a large current at a degree of 20A flows between segments of the conductor 2. And, due to the heat produced by the current, the conductor 2 is forced to melt.

Title: Method for transferring rugged pattern and device for transferring rugged pattern
Inventor: SUGAWARA SEIZO
IPC: G02F1/1337
Filed: 1991-11-19
Abstract: PURPOSE:To enable the sure transfer of a rugged pattern by providing a mechanism which curves a deformable mold formed with the rugged pattern to be transferred on its surface so as to project a part thereof to the front surface side. CONSTITUTION:An upper plate 1 and a lower plate 2 are kept preheated and a material 17 to be transferred is set in this state on the lower plate 2. On the other hand, compressed air of a prescribed pressure is supplied to the air supply path 9 of the upper plate 1 and the mold 4 having the rugged pattern corresponding to the rugged pattern of the oriented film to be formed on its rear surface is curved downward to an arc shape by this pressure, by which the mold 4 is made into the state of projecting the central part. The most downward projecting central part of the mold 4 first comes into contact in a line form with the resin film 15 of the material 17 to be transferred when the upper plate 1 is lowered in this state. In succession, the mold 4 is deformed along the shape of the material 17 to be transferred and the contact range is gradually widened when the upper plate 1 is further lowered. The contact range is thus widened over the entire range to be transferred with the rugged pattern in the final.

Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To recycle thermosetting waste plastic by treating the waste thermosetting plastics with super-critical or sub-critical water to convert them to recyclable and valuable substances as monomers, oil, gas and the like. SOLUTION: The thermosetting waste plastics as epoxy resin, phenolic resin, urea resin, melamine resin and the like are smashed and crushed, classified and recovered. The classified resin is hydrolyzed with water under the super- critical or sub-critical conditions and converted to monomers, oils, gasses and the like and they are reused. The amount of gasification is monitored as an indicator of the decomposition of the plastics and the detection is fed back to the decomposition conditions to increase the yield of the objective substance. Thus, thermosetting plastics can be converted to monomers, oils, gasses and the like and they can be used again. In another case, these gasses and oils can be used to heat the water for decomposition.
