Title: Non-aqueous electrolyte battery
Inventor: TAKAHASHI MASATOSHI
IPC: H01M4/587
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain a non-aqueous electrolyte battery with easy injection of electrolytes by arranging a graphite material as a negative pole active substance so that the planar direction of a grid face (002) is vertical toward the negative pole core body. SOLUTION: In a non-aqueous electrolyte battery using a negative pole active substance, mainly graphite material, the planar direction of graphite particles (002) is arranged vertically toward a negative pole core body. The inter-layer graphite is arranged vertically toward the negative pole core body, when electrolyte is injected the electrolyte can be injected over the entire inside of the negative pole efficiently. Since the electrolyte is sufficiently held to the inside of the negative pole active layer, the battery characteristics of high-rate discharge or the like is improved.  Since graphite particles are arranged vertically toward the negative pole core body, if a relatively soft copper foil is used for the negative pole core body, the tip end of the graphite particles cuts into the copper foil and the close contact with the negative pole core body and the negative pole active layer can be increased.

Title: Method and device for producing sheet-shaped light transmission body
Inventor: NIEDA YOSHIAKI
IPC: G02B6/06
Filed: 1988-03-04
Abstract: PURPOSE:To efficiently produce a sheet-shaped light transmission body having no overlap parts of optical fibers and having an excellent light transmission characteristic by fusing and spinning many optical fibers and joining optical fibers in the lengthwise direction to arrange them like a sheet in the uncooled state. CONSTITUTION:Many optical fibers F1 are spun from a spinning nozzle 1, where orifices 11 are arranged in a circle, and are linearly arranged by a grooved guide 2 without crossing neither contacting, and a tension is applied to these optical fibers by a guide 3 placed under the guide 2 to stabilize the flow of optical fibers. Since a melt-fixing guide 4 placed under the guide 3 has a recessed curved surface in the center, optical fibers are gathered and joined. Optical fibers F4 joined in this manner are approximately linearly arranged and melt-fixed and are taken off by a take-off roll. Thus, the sheet- shaped light transmission body which is uniform and is free from overlap of fibers and meandering distortion and is superior in light transmission characteristic is efficiently produced.

Abstract: PURPOSE:To preclude the possibility of provision of distortion to a reproduced waveform by adopting the constitution with the 1st main magnetic pole recording a signal at the center of track, the 2nd main magnetic pole recording a signal to edges of track with a prescribed angle to the 1st main magnetic pole and an exciting coil. CONSTITUTION:An exciting core 11 is excited by flowing a high frequency recording data signal to an exciting coil 10 via a modulation circuit 4 and a recording amplifier 5 to form a magnetic path passing through the 1st and 2nd main magnetic poles 8, 9 and a data signal is recorded on a medium at the edge at the back of the 1st and 2nd main magnetic poles 8, 9. The recording data 13a, 13b have a tilt angle theta and only the data 13a is reproduced by the 1st main magnetic pole 8 at reproduction. Since the 2nd main magnetic pole 9 is formed thick, the data signals 13a, 13b being high frequency signals cannot be reproduced. Thus, the data 13b is recorded but cannot be reproduced, and the same effect as AC erasure is obtained and tunnel erasure is applied. Thus, no data track is reduced and no distortion is given to the reproduced waveform.
