Patent JP-H022225-A (JP)
Title: Remote controller
Inventor: ISHIZUKA YOSHIYUKI
IPC: H04B10/114
Filed: 1988-06-13
Abstract: PURPOSE:To operate its own equipment without interrupting the operation of other equipments by using a spectroscope and a slit plate for a photodetection and a light emitting section of the remote controller so as to limit the range of a wavelength of an infrared ray. CONSTITUTION:An infrared ray having a wavelength of a band width coming from an infrared ray fighting section 1 is given to a spectroscope 2, where rays are separated depending on the wavelength and the result is radiated through the slit plate 3 to output an infrared ray with a narrow band width. The radiated ray passes through a light collection guide 4 to make the angle of the ray radiated to the spectroscope 5 constant. The separated ray is received by a photodetection section 7 through the slit plate 6 at a position corresponding to the band of the radiated ray. Simultaneously, the ray of other band radiated from a remote controller 8 cannot transmit through the slit plate 6 because of the difference of the refracted angle by the spectroscope and is not received. Thus, the photodetection is operated without interference from the infrared ray from other light emitting section.

Title: Method for producing formed board with cotton-like fiber and formed board produced thereby
Inventor: SHIODA HIROICHI
IPC: D04H1/4258
Filed: 1994-06-02
Abstract: PURPOSE:To obtain a formed board having remarkably improved strength by applying a density gradient to a formed board made of a cotton-like fiber in such a manner as to have a dense composition at the surface layer and the back layer compared with the intermediate layer. CONSTITUTION:This formed board having increased strength and reduced weight can be produced by mixing defibrated cotton-like fiber (e.g. defibrated waste paper fiber) with <=7wt.% (or 5-20wt.%) of a binder composed of a synthetic resin (e.g. synthetic urea resin) for bonding the fibers with each other and carrying out a preparatory tightening process comprising the pressing of the mixture at the normal temperature for a prescribed period and the release of the pressure. The preparatory tightening process is repeated several times to apply a density gradient in such a manner as to give higher density at the surface layer and the back layer than at the intermediate layer. A biodegradability by microorganisms, etc., can be imparted to the formed board by using <=7wt.% of the binder.

Title: Printing belt type sealing instrument
Inventor: KURUTO SHIYUROTSUTSU
IPC: B41K1/10
Filed: 1981-09-16
Abstract: This invention relates to a belt printing mechanism with parallel mounted endless type belts which carry on their exterior surface print types. These type belts extend around an adjustment wheel and a plurality of star wheels where the star wheels are rotatable about a shaft where each star wheel has four corners. A catch mechanism is held under tension against the star wheels and holds these in predetermined detent positions to prevent free rotation of the star wheels. When printing multi-character symbols, the selected print types of adjacent type belts must be brought into predetermined printing positions. In order to assure a clean print copy, care must be taken that the print types rest in the exact same line height. In order to accomplish this, the catch mechanism for each star wheel is provided with a spring tongue which touches at least two separated points of the perimeter of its associated star wheel between two adjacent corners thereof. The plane of each spring tongue with respect to the plane in which its associated star wheel rotates is an acute angle. When the type belts are adjusted, the catch mechanism generates pressures which are clearly recognizable by the operator and which simplify the procedure of bringing the print types into their predetermined printing positions.

Title: Method of forming insulation film
Inventor: ENDO KAZUHIKO
IPC: C23C16/44
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent film peeling by locally varying the F concn. during deposition of an insulation film and lower the moisture absorption by optimizing the F concn. SOLUTION: For forming an insulation film by a plasma-excited chemical vapor deposition using a compd. having bonded F atoms, the pressure at the vapor phase deposition is controlled for controlling the dissociation of a raw material gas in the plasma. As the dissociation proceeds, radicals having low F content become dominant in the plasma, thereby controlling the F content in the insulation film. This reduces the F content or locally lowers the F content at a surface of the insulation film which contacts other film, thereby reducing the moisture absorption and preventing peeling.
