Title: Optical spectrum analyzer
Inventor: KIMURA SADASUKE
IPC: G01J3/18
Filed: 1988-09-21
Abstract: PURPOSE:To efficiently measure secondary diffracted light by providing plural sets of an exit slit and detector to one diffraction grating. CONSTITUTION:Light from an entrance slit 1 are diffracted by a diffraction grating 7 after the light are changed to parallel beam by means of a collimator mirror 2. Diffracted light 13 are reflected by a telemeter mirror 3 and converged to the position of an exit slit 5 and diffracted light 14 are reflected by another telemeter mirror 4 and converged to the position of another exit slit 6. The light passed through the slit 5 are detected by means of a detector 8 through a filter 10, but only primary diffracted light are detected by a synergetic effect with the filter 10 which cuts off secondary or higher diffracted light. On the other hand, the light passed through the exit slit 6 are detected with a detector 9 through a filter 11. The detector 9 mainly detects secondary diffracted light by a synergetic effect with the filter 11 which cuts off high-order diffracted light of higher than the tertiary order. Moreover, the positional relations among the mirrors 2-4, slits 5 and 6, and grating 7 are fixed and wavelength scanning is performed by rotating the grating 7.

IPC: H01M8/24
Filed: 1985-10-25
Abstract: PURPOSE:To increase pressure loss in the inlet and the outlet of a cell, reduce hydrostatic pressure effect caused by gas density difference, and make flow rate distribution uniform by arranging a resistance which produces flow resistance in the front of cell stack on fuel gas inlet side and/or the surface of cell stack on its outlet side.

The flow resistance 8 produces resistance to fuel gas supplied, and any resistance such as porous plate which produces large pressure loss compared with hydrostatic pressure effect can be used for the flow resistance 8. In pressure distribution in the inside of manifold of the inlet and outlet of fuel cell, since pressure difference between the inlet and the outlet is increased by the flow rate resistance plate, the upper part pressure difference DELTAPtop and the lower part pressure difference DELTAPbottom are increased, and the ratio of pressure difference in the upper part and the lower part (DELTAPtop/DELTAPbottom) becomes nearly 1. Therefore, the flow rate distribution in a cell height direction is made uniform.

Abstract: PURPOSE:To ensure the balance of insulator strings at the of one string as well as in a normal condition by fitting the tower side of an insulator string to a steel tower with a single point support via the specified yoke of a single yoke piece. CONSTITUTION:When a center insulator string 5b is broken, small yokes 6 and 7, links 8 and 9 and a center yoke 10 shift to positions to constrain one another due to the weight of a conductor. And right and left insulator strings 5a and 5c are kept balanced about an axial line 15 in the condition wherein said strings 5a and 5c are moved slightly nearer a center axial line 5. A load is thereby shared by the insulator strings 5a and 5c equally. On the other hand, when one of the right and left insulator strings 5a and 5c, or, for example, the string 5c is broken, a simplified yoke 4 and the small yoke at the broken side turn in a direction causing the separation thereof. Concurrently therewith, the sound yoke 6 and the outer yoke 10 turn in such a way that the insulator strings 5a and 5b will come to both sides of an axial line 22 connecting the support point thereof to the support point of the yoke 10. And the insulator strings 5a and 5b come to be located in parallel to and at an equal distance from the axial line 22, thereby sharing the load equally.
