IPC: H01S5/343
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To realize a structure of a laser element of indium,/potassium/ aluminum/arsenic mixed crystal and a ridge-loaded type which can be realized by a simple manufacturing method and can operate at a low threshold and at a high speed with high output, and also to provide a method for manufacturing the element and a light transmission device using it. SOLUTION: Upon manufacturing an optical waveguide of an InP-based ridge load type, an InGaAlAs mixed crystal having a composition wavelength of 1.16 μm or higher is used for an etching stop layer 211 to obtain desired ridge waveguide shapes (212, 215). In particular, when a ridge sidewall is made in the form of an inverted mesa, element characteristics are greatly improved through the enlargement of an electrode contact width and constriction of a light emission region, thus forming a light transmission device.

Title: Method of forming composite oxide superconducting thin film at low temperature
Inventor: TANAKA SABURO
IPC: C01B13/14
Filed: 1988-12-26
Abstract: PURPOSE:To make it possible to execute a method of forming a composite oxide superconducting thin film at a low temperature capable of using a semiconductor single crystal substrate and to make it possible to form the superconducting thin film, which has superior superconductivity characteristics and has uniform composition and structure, by a method wherein a sputtering is performed on the substrate applied a negative bias voltage without heating the substrate using a heating means. CONSTITUTION:A bias voltage within a range of 1-500V is applied to a substrate without heating the substrate using a heating means to perform a magnetron sputtering. When the bias voltage is applied to the substrate, the atoms or ions, having high energies, of a sputtered target reach the substrate. Therefore, even if the temperature of the substrate is low, a thin film having good crystal properties is formed. The temperature of the substrate rises to 200-300 deg.C at most. Accordingly, it is also sufficiently possible to use a semiconductor single crystal substrate as the substrate. Moreover, a stress that a composite oxide superconducting thin film receives from the substrate is also small due to the difference in thermal expansion coefficient in a heating-cooling process. Accordingly, it is possible that materials, which have not been able to be hitherto used, are also used as the substrate.

Title: Scroll compressor
Inventor: TANAKA JUNYA
IPC: F04C18/02
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate passage resistance by pulsation of delivery gas, vibration and the seating sound of a deliver valve by constituting respective compression spaces so as not to simultaneously communication with a delivery hole. SOLUTION: The timing for communicating with a delivery hole is constituted to become before starting delivery in a compression space A and in the middle of compression in a compression space B so that each timing for delivering delivery gas becomes different each other by almost 180 deg.. Thus, delivery of the delivery gas is started in the compression space A, and while, the delivery becomes in the middle of compression in the compression space B, so that the deliver is started from the compression space B after turning a lap of a turning scroll by 180 deg.. Generation of pulsation of the delivery gas is prevented by the delivery hole, and an increase in passage resistance is prevented. A repetition of opening/closing of a delivery valve by high pressure delivery gas is prevented to eliminate a cause of noise by the seating sound of the delivery valve.
