Title: Alkaline battery separator
Inventor: TANAKA MASANAO
IPC: H01M2/16
Filed: 1993-01-14
Abstract: PURPOSE:To improve the preservability of an electrolyte and prolong a use life by adopting a sheet, composed of specific components 1 and 2 respectively and including a composite fiber in which the component 2 is partially positioned on a fiber surface, as an alkaline battery separator. CONSTITUTION:A composite fiber 3 used for a separator is composed of mainly an alkali-proof resin component l and an ethylene-vinylalcohol copolymer component 2, and the copolymer component 2 is positioned partially on a fiber surface, consequently is excellent in affinity with an electrolyte and also in liquid- preservability. Even the copolymer component 2 is eluted in an electrolyte, the electrolyte can be preserved in a space occupied by the copolymer component 2, eliminating the lowering of the preservability. Since ethylene-vinylalcohol copolymer is not causing self-discharge like polyamide resin, a separator using the composite fiber 3 can prolong a use life.

Title: Imaging pick up device for three dementional shape measurement
Inventor: YONEYAMA JUICHI
IPC: G06T7/00
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To pick up an image for 3-D shape measurement even under general light by comparing pixel outputs for two pictures photographed by turning on and off slit lights by turns and detecting pixels of slit pattern. SOLUTION: A control part 16 initially sets a slit projector 15 at off-state, makes imaging pixels 14 imaging-function under general light, takes difference signal between image frames in turn and judges the degree of variation (motion) of a sample 11. When a meaningful variation occurred, the projector 15 is turned off synchronizing with charge accumulation at odd number frames and turned on synchronizing with charge accumulation at even number frames. As the results, slit pattern is not included in the acid number frame output from imaging element 14 and slit pattern is included in the even number frame. Thus, for the pixels of which difference signal of both images exceeds a threshold, an operation process part 18 obtains 3-D coordinate values of a cross point of the sight line of the pixel and the slit beam plane and outputs outside in turn.

IPC: F16G13/02
Filed: 1989-02-01
Abstract: PURPOSE:To provide friction resistance and corrosion resistance with a load in use equal to a roller chain of JIS standard by fitting and securing a pin to an outer side link plate, consisting of stainless steel material having predetermined hardness, with fitting force 5 to 10% the breaking strength of the chain. CONSTITUTION:Of the parts constituting a chain, at least an outer side link plate 1 is constituted of stainless steel material of Ni-Cr-Mo system or Ni-Cr-Cu system with its hardness HRc32 to 43, and fitting force to a pin 2 is set to 5 to 10% breaking strength of the chain. The above data is caused by a reason that the outer side link plate deteriorates friction resistance not endurable for use with mechanical strength insufficient as the link material, when the hardness of the plate 1 is less than HRc32, while decreases toughness dropping an impact value disabling a stress corrosion crack from being prevented when the hardness exceeds HRc. While the reason is that the pin 2 rotates generating large friction, when its fitting force to the outer side link plate 1 is less than 5% the breaking strength of the chain, and a stress corrosion crack can not be prevented when the fitting force exceeds 10%.
