Title: Porous tube of polytetrafluoroethylene and its manufacture
Inventor: NISHII HIROYUKI
IPC: C08J9/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To form layers of different pore structure by first, applying a dispersion of polytetrafluoroethylene powder to a porous tube, and removing by evaporation the coat through heating it, and further, integrating particles of polytetrafluoroethylene to each other by heating them above a melt point to stretch in a uniaxial direction. SOLUTION: A paste-like mixture comprising fine powder of polytetrafluoroethylene(PTFE) and an organic solvent as an extrusion assistant is performed. After that, the performing is transferred to the cylinder of an extruder to be extruded in the form of a tube. This extruded product is stretched in a longitudinal or a diametrical direction to make it porous. Further, a PTFE dispersion is coated to the stretched product. In additon, the coat is dried by an air and then is placed in a dryer at about 100 deg.C to remove a solvent from the dispersion by evaporation. Next, this solvent-free coat is heated above a melt point, resulting in a change in the pore diameter and porosity of the coat ensuring from a change in the integrity of particles. Finally, the coat is stretched which in turn, causes the coat to be porous and consequently, the porosity to further augment.

Inventor: NEMOTO HIROSHI
IPC: H01M10/0525
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a lithium secondary battery in which decrease in capacity and increase in internal resistance attendant on charge/discharge cycles are retarded, and provide the manufacturing method of a positive active material suitable for the lithium secondary battery.

Title: Optical information recording/reproducing device
Inventor: TEZUKA KOICHI
IPC: G11B11/105
Filed: 1994-06-17
Abstract: PURPOSE:To enlarge an allowable margin of a focus error detection system of a Foucault method and to obtain a correct signal by providing a photodetector corresponding to an optical element deflecting a part excepting the center of a reflected light beam to plural positions. CONSTITUTION:By the reflected light beam transmitting through tapered parts 15a, 15b of a composite prism 15 constituting a focus servo system, spots are formed on respective bisected photodetectors 16a, 16b of a quadripartite photodetector 16. By operating the outputs, a focus error signal is obtained. On the other hand, the reflected light beam transmitting through the central part 15c of the prism 15 is made incident on the central part 16c of the detector 16. Since the spot formed in such a manner becomes an ellipse shape long in the direction perpendicular to the division line E of the detector 16, a focus offset occurring due to the deviation in the division line E is quite smaller, and the allowable margin of a focus error detection system for the positional error, etc., of the prism 15 and the detector 16 becomes larger. Further, the prism 15 and the detector 16 may be other shapes, too.
