Title: Polarization diversity part for coherent optical receiver
Inventor: YOHANESU YAKOBUSU JIERARUDASU
IPC: G02B6/126
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To easily integrate elements for mode division and mixture according to a mode degree without metallic elements by applying decision that follows a mode order before or after a mixture operation after performing mode order conversion of a polarization mode in a received optical signal. SOLUTION: An optical signal to be inputted through an input channel (a) is first inputted to the combination 41 of mode converter/splitter which has outgoing monomodal optical channels k' and l'. A mode converter is a 100% TM00 -TE01 mode converter. As a result, a signal that has a polarization mode TE is inputted to different 3dB power coupler 42 and 43 through the channels k' and l', and one of the signals corresponds to a TM component into which a signal inputted through the channel a is converted. A light signal from a light source 12 that has a mode TM is inputted to a symmetrical Y splitter 44 through an output optical channel j, distributed to outgoing monomodal optical channels m' and n' and after that, inputted to the couplers 42 and 43. A signal that exclusively has the mode TM is inputted to output optical channels e' to k' and processed.

Title: Secondary battery
Inventor: OGURA YUKIHIRO
IPC: H01M4/13
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To restrain generation of gas when abnormally overheated by adding polysaccharide in a nonaqueous electrolyte or a positive electrode active material. SOLUTION: Polysaccharide to be added is a kind of curdlan of polysaccharide produced by microorganism, constitutive sugar is a bonded one of only glucose, and is composed of only a β-1, 3 glucoside bond in a structure, and a chemical structure is expressed by the formula. When abnormal heat is applied from the outside, since the curdlan in a nonaqueous electrolyte is gelatinized by taking a large quantity of nonaqueous electrolytes in a molecule and hinders electrode reaction in a battery, heat from the battery can be reduced. Gelatinization is not caused at 130 deg.C or less. An added quantity is desirably 0.1 to 5 wt.%. The curdlan shows high biodegrdability of almost the same degree as corn starch.  When adpoted in a structure for dispersing a binder in an active material tank of a lead-acid battery, the curdlan plays a role of a hole creating agent, enhances porosity of a surface part of a plate, and enhances internal strength of the active material tank.
