Title: Heat transfer recording material
Inventor: MORISHITA SADAO
IPC: B41M5/41
Filed: 1984-04-03
Abstract: PURPOSE:To provide a heat transfer recording material which does not need treatments to be heat-resistant and is inexpensive, by using a polyethylene film having a density of not lower than 0.935 as a sheet form base. CONSTITUTION:A polyethylene film having a density of not lower than 0.935 is used as a sheet form base, in a heat transfer recording material comprising a heat transferable ink layer on the upper side of a sheet form base. A material obtained by blending a high-density polyethylene with a low-density polyethylene may also be used, provided that the density thereof is not lower than 0.935. When the polyethylene film is brought into contact with a thermal head heated to a high temperature (about 300 deg.C), the film is instantaneously melted, but it is not thermally deformed, since the density thereof is high, and the head is moved while the film is left molten. It is presumed that a sticking phenomenon does not occur because polyethylene is low in adhesiveness to the head and serves as a kind of lubricant.

Filed: 1995-03-27
Abstract: PURPOSE: To enable accurate aligment of a gate electrode and a source/drain, by repeatedly emitting light int he direction toward an object, and exposing the object on the thin film transistor substrate to the repeatedly emitted light. CONSTITUTION: A repeating light source means 15 emits UV rays with which photoresist is irradiated. The light is emitted only from the part corresponding with a common light pattern 18 irradiated with a projection light. That is, the repeating light source means 15 makes the UV rays having a repeating light pattern 16 coinciding with the common patten 18 irradiated with the projection light the repeating light as the irradiation light, and repeatedly emits light in the direction of a light projection means 11 in which the photoresist 17 is arranged. The photoresist 17 is exposed to the repeating light. Hence the repeating light pattern 16 coincides with the common pattern 18, and the exposed photoresist pattern becomes a pattern coinciding with the common light pattern 18.

Title: Thin film el element
Inventor: KIZAWA KENICHI
IPC: H05B33/22
Filed: 1988-03-23
Abstract: PURPOSE:To obtain a thin film EL element having a stable luminous characteristic by using sulfide having high thermodynamic stability as an insulating layer material in contact with a luminous layer. CONSTITUTION:A part or the whole of the first insulating layer or the second insulating is composed of a film consisting of sulfide having high thermodynamic stability so as to make a film consisting of sulfide having thermodynamic stability to contact with a luminous layer. That is to say, a sulfide thin film layer of a group IIIb and rare earth is inserted in contact with the luminous layer. Sulfide of the group IIIb and rare earth is hard to be oxidized while having a small diffusion coefficient of oxygen. Accordingly, by using the above- mentioned material for the insulating layer coming in contact with the luminous layer, diffusion of hydrogen from the atmosphere or from an insulating layer material containing hydrogen into the luminous layer can be prevented so as to be able to stabilize an EL luminous characteristic.

Title: Noise preventing structure for roller chain
Inventor: TANAKA KOJI
IPC: F16G13/02
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce the noise which is generated when a chain meshes with a sprocket or scrubs the end face of a roller by forming a convex rail on the peripheral surface of the roller as well as by burying an elastic body in a groove formed on the tooth surface of the sprocket. SOLUTION: A convex rail 6A which is continuous in circumferential direction is formed at the center of the peripheral surface of the roller 6. And, when the roller 6 meshes with the tooth surface of the sprocket 7, the convex rail 6A of the roller 6 first abuts the elastic body 8 buried in the groove 7B of the tooth surface 7A, and reduce the noise generated by collision of the sprocket 7 and the roller 6 owing to buffer action of the elastic body 8.  At this moment, the convex rail 6A deforms elastically the elastic body 8 to immerse it into the groove 7B, and then the convex rail 6A is fit in the groove 7B, so that the roller 6 is positioned at the center of the sprocket, and a gap S is produced between at either end face of the roller 6 and an inner plate 2 on either side, and thus it is possible to prevent generation of scratch noise due to sliding contact between the inner plate 2 and the end face of the roller 6.

Thus, a polymer optical fiber is doped with the dye and the dye, he exciting light, a signal light can be confined in a narrow range for a long distance, and energy density can be enhanced. The light can be very efficiently amplified by increasing a length of a mutual operation.
