Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission device provided with an optical planar waveguide provided with transmission characteristics independent of a temperature without using a temperature control device for preventing the shift of the center frequency of the waveguide and the optical transmission device by passive control to the thermal effect of the planar optical waveguide. SOLUTION: A substrate 16 supports a base material 13 and an optical core part 14, a control material 22 is adhered to the lower part of the substrate and the thermal expansion coefficients of the control material 22 and the substrate 16 are different. Corresponding to the rise and decline of an ambient temperature, the control material 22 is thermally expanded and contracted by a rate different from the substrate 16, non-planar substrate distortion transmitted to the optical core part 14 is generated and thus, the temperature dependency of an optical path length inside the optical core part 14 is opposed. In this case, the control material 22 is provided with the thermal expansion coefficient larger than the one of the substrate 16, compression force to the optical core part 14 is generated and the thermal expansion of the optical core part 14 is opposed.

Inventor: TACHIKI HIDEYASU
IPC: B29D99/00
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To restrain generation of edge fusion by winding a proper film in an area where a multilayer film of a branch pipe is to be taken up so as to thicken the center of the pipe, satisfying expressions and a specified condition, and taking it up. SOLUTION: In a cylindrical coordinates, a longitudinal direction of a branch pipe 1 is set to (x) axis, the center of the branch pipe is set to an origin O, and an area of a multilayer film 4 at the time of take-up is set between -W and W in the (x) coordinate. An area where the film is to be wound on the branch pipe 1 so as to change its thickness is made to be an area where the multilayer film 3 is to be wound. A reference radius of the branch pipe 1 is set to R0 and a radius R (x) of the branch pipe of an optional point (coordinate x) on the (x) axis is set to R (x)=R0 +r (x) [r (x) is an increment, a continuous function of (x), r (x) >=0, r (-W) =r (w)=0].  When a start torque of taking up is TS and an end torque is TE (TS=TE or TS>=TE>=0.5S, a torque midway in taking up is set to be constant or monotonously decreasing), taking up of the film is performed in such a way that an expression I (E is a modulus of elasticity in tension per unit width of the multilayer film) can be established and an integration (S) satisfies conditions of an expression II [r (x) is an average value of r (x) for the circumference direction of the branch pipe] and of an expression III.

Title: Solar cell
Inventor: KITABI SHIGERU
IPC: H01L31/04
Filed: 1987-11-06
Abstract: PURPOSE:To prevent the powder generation of inverse direction in a P-N junc tion part, by a method wherein a light from a first main surface side is absorbed by a third semiconductor layer, while a light from a second main surface side is reflected by an electrode, and light is made not to reach the P-N junction part. CONSTITUTION:When a light enters the light receiving surface of a solar cell, photoelectromotive force generates between an N-type GaAs layer 3 and a P-type GaAs layer 4, and acts as a battery wherein an anode 12 is positive and a cathode 13 is negative. Since the layer 4 and an N-type GaAs layer 5 is short-circuited by an anode 1, they do not contribute to photovoltaic effect. A P-N junction constituted of the layer 5 and an N-type GaAs layer 6 has, from the nature of it, power generation function inverse to the power generation direction of the solar cell. But light having a wavelength effective in power generation in incident light from the light receiving surface side is absorbed by the layer 5 and a P-type GaAs layer 7. On the other hand, incident light from the rear side is shielded by the cathode 13, so that a light does not reach the P-N junction. Therefore power generation in the inverse direction can be prevented.

Title: Sheet metal connection by screw in cooking machine
Inventor: YAMAGUCHI SHIGERU
IPC: F16B5/02
Filed: 1988-11-08
Abstract: PURPOSE:To prevent a screw from losing its effect because of expansion of a burring diameter when another part is attached to a sheet-metal-made-part through screw connection by forming the burring part at the top of an indentation having a conical or spherical shape. CONSTITUTION:A tap tightening screw 13 is screwed through self-tapping to a burring part 14 of a sheet metal body 11 via a hole 16 made in a resin body 12. When torque is applied to the screw, the sheet metal body 11 is subjected to the force in the B-direction. In this case, however, since a burring part 14 of the sheet metal body 11 is formed at the top of an indentation 15 having a conical shape, the force in the B-direction is dispersed as the force in the direction, which reduces the diameter of the burring part 14. Accordingly, the burring part 14 tends to tighten the threaded part of the screw 13, thereby preventing the screw 13 from losing its effect.
