Patent JP-H053038-A (JP)
Title: Fuel cell
Inventor: YAMAGUCHI MASANORI
IPC: H01M4/86
Filed: 1991-06-25
Abstract: PURPOSE:To lengthen the life in its operating hour by designing the diameter of at least one orifice, in a rim part of a fuel pole or an oxidizer pole among a rib part, an electrode, and an electrolyte layer, to be smaller in its upstream than that in its downstream in the gas flow direction. CONSTITUTION:In a fuel cell comprising separators 1, gas grooves 3, a rib part 2, an electrode 4 forming a passage for supplying a fuel or an oxidizer from the gas grrove 3 to a catalyst layer 5, and an electrolyte layer 6 for selectively passing hydrogen ions generated in a fuel pole to an oxidizer pole: the average orifice diameter, formed in a rib part 2, an electrode 4, and an electrolyte layer 6, has smaller one in its upstream A than that in its downstream B in the gas flow direction. Whereby, phospheric acid scavenged at more down stream sides in respective gas stream can more easily be returned to its more upstream sides, so that the resulting activation of uniformity of the phosphoric acid distribution in a cell can lengthen its operating life.

Title: Sneak path canceller
Inventor: IMAMURA KOICHIRO
IPC: H04J11/00
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To realize a single frequency network(SFN) by means of stable broadcast wave relaying in digital transmission of an orthogonal frequency division multiplexing(OFDM) signal. SOLUTION: A sneak path transmission characteristic in an OFDM signal band is estimated from a characteristic of a signal in the OFDM signal band (3, 4), a sneak path transmission characteristic at the outside of the OFDM signal band is extrapolated from the result of estimating the sneak path transmission characteristic in the OFDM signal band (3, 4), and a sneak path not only in the OFDM signal band but also at the outside of the OFDM signal band is cancelled by using the extrapolated sneak path transmission characteristic (5). Thus, the oscillation at the outside of the OFDM signal band that is a problem when a strong sneak path is in existence can be prevented to realize an SNF by stable broadcast wave relaying.

Title: Well-ordered wire winding device
Inventor: WATANABE MASATO
IPC: B65H54/28
Filed: 1985-07-13
Abstract: PURPOSE:To make it possible to perform naturally well-ordered winding to cope with small-sized electronic components by installing a pulley which serves as a wire winding guide over a base shaft set up in parallel with a core member, with the pulley freely slidable and rotatable over the base shaft. CONSTITUTION:A core member 2 is installed over a rotary shaft 1, with a base shaft 3 set up in parallel with the core member 2. The base shaft 3 is set up on a location-adjustable support arm 4 so that the relative distance from the core member 2 is adjustable. Over the base shaft 3 is installed a pulley body consisting of a thrust bearing 5 of nylon or the like and a pulley 7 with a bearing 6 interposed in between. While a wire 8 is wound via the pulley 7 over the rotating core member 2, travel of the pulley 7 along the base shaft 3 according to the winding process is affected by friction between the base shaft 3 and the pulley 7, tension of the wire 8, and the distance between the pulley 7 and the core member 2. Winding work is performed with the aforementioned factors suitably adjusted. Thus, without any special control, naturally well-ordered winding can be performed, making it possible to cope with the need for the small size required of electronic components.
