Title: Light emitting diode and its manufacture
Inventor: WATANABE NOBUYUKI
IPC: H01L33/30
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a light emitting diode having the structure of a highly efficient and inexpensive GaP light emitting diode, without damaging the inside parts of a crystal and to provide a manufacture method. SOLUTION: A first n-type GaP epitaxial layer 2 is formed on the surface of an n-type GaP substrate 1 through a liquid phase epitaxial growth method. A second n-type epitaxial layer 3 is formed on the rear side of the n-type GaP substrate 1. Then, a third n-type GaP epitaxial layer 4, a first p-type GaP epitaxial layer 5 and a second p-type GaP epitaxial layer 6 are sequentially formed on the surface of the first n-type GaP epitaxial layer 1. In the epitaxial growth, a mirror surface state is formed on the back side by the second n-type epitaxial layer 3 formed on the rear side, as the reflectance on the rear side becomes high and newly polishing of the back side to mirror-plane level after the completion of epitaxial growth is dispensed with.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To substantially reduce labor of adjustment work at the time of installation for a simplified structure by disposing a plurality of coil springs between a stator and a stator supporting frame, and absorbing the vibration of the stator with the coil springs. SOLUTION: On a stator-supporting frame 2, a pair of spring mounting seats are vertically fitted on both sides of a stator 1, that is, at symmetrical positions with respect to the stator, and on both sides of the stator 1, a spring-mounting seat 20 is fitted. Between the mounting seat 10 and the mounting seat 20 serving as a pair each other, a plurality of coil springs 6 are disposed along a parallel direction to the center line of the stator 1. The stator 1 is supported by the stator-supporting frame 2 via a plurality of coil springs 6. Therefore, the circular vibration of the stator is absorbed in the coil spring 6. It is thus possible to facilitate adjustment at the time of installation and simplify the protective structure of the spring against excessive torques.

Title: Single operation type adhesive tape with gauze for finger
Inventor: ARAKI NORITOSHI
IPC: A61F13/10
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To provide the subject tape capable of enabling a user to apply it to a wound of his/her finger by a single hand by forming a substrate paper strip longer than an adhesive tape strip, and making loose the vicinity of the center of paper strip so that a finger can enter sufficiently. SOLUTION: This is an adhesive tape with gauze whose substrate paper strip is longer than its adhesive tape strip and the vicinity of the center of the paper strip is made loose so that a finger can eneter sufficiently. Conventionally, it is inconvenient to peel an adhesive tape strip with gause from a substrate paper strip and to apply it to a wound part or the like. Furthermore, it is more hard to perform a series of the operation with one hand. To solve such a drawback, this adhesive tape strip with gauze is provided which can be applied by one hand easily by making a wound finger enter a loose part 4 so that the wound part 4 may come to the position of the gauze, and pulling a loose end 3 in the arrow mark direction. In this tape, no mutual sticking between adhesive portions occur and after the use it can be disposed in a combined style.

Title: Production of colored thermoplastic resin
Inventor: KUMASAKA SADAO
IPC: C08J3/20
Filed: 1983-06-20
Abstract: PURPOSE:To produce a colored resin quickly and simply without degradation of a resin, pigment, etc., while freely selecting a colorant, by uniformly dispersing a colorant in a thermoplastic resin solution and separating the resin containing the colorant from the resin solution. CONSTITUTION:A resin solution is prepared by dissolving a thermoplastic resin to be colored in a solvent and a colorant (a pigment or a dye) is uniformly dispersed in the solution. The resin containing the colorant is separated from the resin solution in which the colorant is uniformly dispersed. In this way, a colored resin can be obtained simply and rapidly. Unlike a conventional process wherein a colorant is mixed with a molten thermoplastic resin, this process allows one to obtain a colored resin within a short time without degradation of a resin, pigment, etc., due to a prolonged high-temperature kneading. Further, while a colorant having a decomposition temperature lower than the processing temperature can not be used in conventional processes, it is possible to select a colorant freely in this process.
