IPC: G02B6/12
Filed: 1992-06-04
Abstract: PURPOSE:To provide the optical front end which is smaller in size than the optical front end constituted by using optical fiber couplers connected serially in two stages, has no dependency of a branching ratio on polarization and improves the controllability of the branching ratio. CONSTITUTION:This optical front end consists of a polarization separating coupler 1 which is an optical waveguide or directional coupling type polarization separator consisting of a polarization separating fiber coupler which separates the light beam made incident from incident ports 12A and 12B respectively to TE polarized light and TM polarized light and emit these light beams respectively from exit ports 13A and 13B and double refractive plates 2A, 2B which consist of transparent materials having the double refractiveness obtd. by cutting and polishing the materials in parallel with the plane inclining at the inclination of the normal larger than 0 deg. and smaller than 90 deg. with the optical reference axis Z of the crystal and consist of, for example, TiO2 or calcite for branching the intensity of the incident light from the polarization separating coupler 1 to 1/2.

Title: Alkaline battery
Inventor: TANAKA HITOSHI
IPC: H01M2/08
Filed: 1994-06-27
Abstract: PURPOSE:To restrain excess gas from being linearly emitted, and thereby narrow a range of splashing by forming a cut-out section through which gas within a battery is emitted while being communicated with a explosion proof mechanism, in a terminal plate sealing a metallic case including a power generating element. CONSTITUTION:A metallic case loaded with a power generating element is sealed with a resin sealing body 5, and a negative electrode current collector 10 is integrally fitted in its thick wall section 13. The thin wall section 6 of the sealing body 5 is opened because of an increase in inner pressure due to gas produced, and the gas containing electrolyte is emitted to the outside of a battery out of a cut-out section 11 provided for a negative electrode terminal plate 9 through the through hole 8 of a washer 7. Since the cut-out section 11 is in a linear shape, emitted gas is once in contact with the inner surface of the terminal plate 9 so as to let electrolyte be removed, and it is not linearly splashed over in a wide range. In this case, it is preferable that the cut-out section is non-linear in shape, a slice 12 in an oval shape, a triangle shape and the like are formed, and the most part of electrolyte is removed by its rocking motion. Beside, it is more effective that the slice 12 is inclined toward the inside of the terminal plate 9.
