Title: Optical waveguide and its production
Inventor: ISOKAMI MINEO
IPC: G02B6/13
Filed: 1991-10-31
Abstract: PURPOSE:To produce an optical waveguide with a little lattice defect causing a light scattering loss, and capable of extremely preventing the variance of the optical characteristic and deterioration and obtaining a good optical waveguide characteristic with good reproducibility. CONSTITUTION:A waveguide layer F having a higher refractive index than the lithium niobate single crystal and consisting of a transparent single crystal thin film is formed on the substrate S of a lithium niobate signal crystal to form the optical waveguide. Consequently, the problems of the conventional metal diffusion layer disappear, and the optical characteristic is hardly varied between the discrete optical waveguides. In addition, the difference in the refractive index between the substrate S and the waveguide layer F is effectively controlled, hence the light transmission loss is minimized, and an optical waveguide minimized in the variance is provided with good reproducibility.

Abstract: PURPOSE:To make highly accurate control over an oil flow rate performable by installing a connecting hole feeding lubricating oil in an oil sump to a back pressure chamber by way of an eccentric drive bearing from at least a space and a connecting port or void where oil in the back pressure chamber is interconnected to a compressive working space, and setting up a throttle resistance part in the said connecting port. CONSTITUTION:Lubricating oil having a main bearing19 lubricated flows into an ambient space 38, lubricating an eccentric drive bearing 15, and it reaches an end space 41 of a turning shaft 14.

Title: Optical recording medium
Inventor: ITO MASAKI
IPC: G11B7/243
Filed: 1985-12-19
Abstract: PURPOSE:To improve the weatherability, sensitivity and signal quality of an optical recording medium which is provided with a layer essentially consisting of a tin oxide on one side of a substrate and records and reads information by the irradiation of laser light by forming a silicon oxide layer between the substrate thereof and the layer essentially consisting of the tin oxide. CONSTITUTION:The tin oxide is selected in terms of weatherability and the size of a refractive index for the material of the 1st spacer layer 1 and the thickness thereof is so elected as to increase reflected light. Incident light through the substrate 10 is partly reflected by the boundary face between the substrate 10 and the 1st spacer layer 1, the boundary face between the 1st spacer layer 1 and the 2nd spacer layer 40 and the boundary face between the 2nd spacer layer 40 and air. The material and thickness of the 2nd spacer layer 40 are so selected as to decrease the reflected light. The difference in the rate of moisture absorption near both faces of the synthetic resin substrate is substantially eliminated by inserting the silicon oxide layer 2 between the synthetic resin substrate and the tin oxide layer 1 which is the 1st spacer layer and therefore, the generation of warpage is prevented.
