Title: Cyanoacrylate composition
Inventor: UEMURA HIROSHI
IPC: C07C253/00
Filed: 1987-09-22
Abstract: PURPOSE:To obtain a cyanoacrylate composition having improved adhesive performance, by adding ethylene carbonate to a 2-cyanoacrylate. CONSTITUTION:Ethylene carbonate is added to a 2-cyanoacrylate formula (R is 1-8C alkyl, cycloalkyl, etc.) or a mixture of two or more kinds of the cyanoacrylates. The adhesivity of the acrylate increases by increasing the amount of ethylene carbonate until a specific level, especially 30-40wt.%, above which the adhesivity remarkably decreases. The set time of the adhesive also increases by the increase in the amount of ethylene carbonate and becomes nearly constant above a specific content. The addition of ethylene carbonate lowers the hardness and increases the flexibility of cured product. The composition is extremely stable even by decreasing the amount of conventional acidic stabilizer. It is especially useful as an adhesive for artificial nail, a screw- fastening agent, etc.

Title: Method for forming laminate structure with relaxed stress
Inventor: WANG SHIH-YUAN
IPC: H01L33/34
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To provide an improved method for growing a growth layer on a substrate where the thermal expansion coefficient and/or lattice constant of the layer is largely different from that of the substrate. SOLUTION: A GaN growth layer 10 is film-formed on a sapphire substrate 12. The film formation is operated in a sufficiently high temperature, and before this is completely cooled, ultraviolet rays 14 are irradiated from the sapphire substrate 12 side to the GaN growth layer 10. At that time, one part of decomposition layer 11 positioned at the substrate 12 side of the GaN growth layer 10 is decomposed after the ultraviolet rays 14a are received so that any stress generated between both layers can be relaxed or removed. The ultraviolet rays 14 are not irradiated to an island part 13 constituting one part of the boundary face of the both layers so that sufficient adhesiveness of the GaN growth layer 10 to the sapphire substrate 12 can be maintained.

Title: Optical head device
Inventor: MATSUMOTO SEIJI
IPC: G11B7/085
Filed: 1990-09-07
Abstract: PURPOSE:To improve high-speed accessibility without requiring high mechanical accuracy by arranging an objective lens at least at the top part of a rotarty body or the vicinity of it and arranging a light source and a photodetector at a part close to an axial line rather than this. CONSTITUTION:An objective lens 56 is arranged at least at the top part of a turning body 52 or the vicinity of it and a light source 69 and the photodetector are arranged at the part in the vicinity of an axial line 14 rather than this so as to separately arrange the constituting parts of an optical head 50. Thus, in comparison with the case of arranging the entire optical head at the top of the rotary body line in an conventional device, inertia is reduced and high-speed accessibility is improved. Further, since all the separately arranged constituting parts are arranged on the rotary body 52 and integrally moved, there is no problem such as optical axis deviation like a separated type, and the assembly accuracy is not so much required as the separate type.

Title: Image fixing device
Inventor: ONOZUKA MAKOTO
IPC: G03G15/20
Filed: 1987-09-22
Abstract: PURPOSE:To uniform nip pressure to transfer paper in the axial direction of a roller by providing a roller supporting structure provided with an energizing part which displaces one roller to the other roller between roller hand holding parts in the lengthwise direction of a supporting member. CONSTITUTION:The energizing part 10G1 is provided in the lengthwise center of the single supporting member 10G which supports both axial ends of a pressure roller 10E. Then the energizing part 10G1 consists of a cylindrical spring receiver 10G11 and a compression spring 10G12 whose axial end part is fitted in the spring receiver 10G11 and the supporting part of a machine body. Energizing force from the energizing part 10G1 is therefore distributed uniformly to the supporting part of the supporting member 10 for the pressure roller 10E, so both axial ends of the pressure roller 10E to a heat roller 10D have equal press-contacting force. Consequently, the axial press-contacting force between the rollers which abuts on each other is uniformed to prevent transfer paper from being sent slantingly and a defect in fixation from occurring.
