Title: Optical add/drop multiplexer and wavelength-division multiplexing submarine branch system
Inventor: MIYAGAWA TETSUYUKI
IPC: H04B10/27
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce the insertion loss of through optical signal of an optical add/drop multiplexer. SOLUTION: Optical wavelength multiplex signals λ1-λ4 made incident through an incident terminal (INPUT) are made incident to a dielectric multilayer film filter 1 having different transmission wavelengths corresponding to inclination angles and only the optical signal of the wavelength λ2, for example, is extracted (transmitted) and emitted through a drop light emitting terminal (DROP). Besides, the optical signal of the same wavelength λ2 as the optical signal extracted by the filter 1 is made incident through an acid light incident terminal (ADD) to the filter 1 so as to have the same optical axis as the optical signals of wavelengths λ1, λ3 and λ4 reflected by the filter 1.  Then, the through optical signal is formed by synthesizing this optical signal of the wavelength λ2 with the optical signals of the wavelengths λ1, λ3 and λ4 and this is emitted through an emitting terminal (OUTPUT). Since the through optical signal is reflected just once by the filter 1, the reduction of insertion loss can be attained.

Title: Impalpable powder member-porous member for gas diffusion electrode construction and water repellent treatment therefor
Inventor: WATANABE MASAHIRO
IPC: H01M4/88
Filed: 1988-09-16
Abstract: PURPOSE:To improve water repellency and gas supplying ability by covering almost all surfaces of impalpable powder grains or thin fibers with water repellent fine grains, whose average grain diameter is not larger than the grain diameter of the impalpable powder or the diameter of the thin fibers, or with thin films. CONSTITUTION:Almost all surfaces of impalpable powder grains or thin fibers are covered with water repellent fine grains, whose average grain diameter is not larger than the grain diameter of the impalpable powder or the diameter of the thin fibers, or with thin films. Therefore, even if a gas diffusion electrode constructed from these is used as a cathode electrode of a fuel cell for a long time, the electrolyte does not enter through the part not covered with the water repellent grains and the lowering of the supplying ability, due to the blockage of the gas passages formed by the impalpable powder or the thin fibers, can be prevented. Thus, excellent water repellency can be obtained when used as the water repellent material for either the gas supplying layer or the catalyzer layer of the gas diffusion electrode, and the gas supplying ability is not deteriorated.

Abstract: PURPOSE:To cause voltage changing quantity due to a capacity coupling between data lines to be almost zero and to widely decrease a capacity coupling noise by alternatively arranging data paired lines to cross at two spots and data paired lines to cross at one spot and constituting a memory. CONSTITUTION:The data paired lines to cross at the two spots of A and C points and the data paired lines to cross at the one spot of a B point are alternatively arranged and the memory is constituted. Here, when the lengths of four sections BL1-BU4 are made equal, an adjacent distance between a specified data line and the four data lines of the two data paired lines to be adjacent to the data line goes to be equal and the voltage change of the same phase and quantity is received by D2 and the inverse of D2. Further, a driving is executed so that the up and down symmetric voltage change can be executed between D and the inverse of D and between D3 and the inverse of D3. Thus, the voltage changing quantity due to the coupling between the data lines goes to be zero and the delay of a sense amplifier is made minimum. Then, the noise is decreased.

Title: Cryopump
Inventor: IWASA YASUSHI
IPC: F04B37/08
Filed: 1988-09-19
Abstract: PURPOSE:To increase an exhaust speed for helium by providing a blow pipe of the first gas inserted into a hollow part along its center line of a cooling unit and a baffle having an incident surface of gas in a vertical direction with the center line. CONSTITUTION:A baffle, in which exhausted gas passes through an exhaust route reaching an exhaust surface 51 from an incident port 46, is constituted of only a louver blind type baffle 32 for reducing heat radiation. By this constitution, the exhaust route increases its transmission probability of helium larger than in the conventional cryopump. While because an argon condensed layer is formed in a surface almost in a vertical direction with respect to the baffle 32 arranged in an upper front side of the exhaust route, conductance is different by a part of the argon condensed layer for hydrogen or the like of the exhausted gas component passing through the baffle 32, so that concentration on or in the argon condensed layer is different, and the route holds a portion having sufficient ability for helium.
