Title: Optical information recording medium and information reading method
Inventor: TODA TOSHITAKA
IPC: G11B7/24035
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to generate exit light containing little crosstalk at a light-receiving position by decreasing, directly behind a cell and from the center part of the cell toward their peripheral part, an amplitude distribution of exit light from the cell composing a recorded information component of an optical information recording medium for optically reading the recorded information by receiving an exit light pattern produced by irradiation of light beam. SOLUTION: An amplitude modulation is provided so that an amplitude distribution of exit light from each diffraction grating cell composing recorded information on an optical information recording medium is decreased from the central part toward the peripheral part in the horizontal and vertical directions. Both transmission type and reflection type do for reading the optical information recording medium where the black and white parts shown in the figure are made to be phase type diffraction grating expressing phase modulation values maximizing and minimizing the diffraction efficiency. In either case, a photo-detector array for detecting recorded information and reading it is located in a Fresnel zone for the phase type diffraction grating cell.  In such a manner, the photo-detector receives only information light containing little noise and crosstalk, and can correctly read the information as a result.

Title: Supporting insulator with photocurrent sensor
Inventor: SHINODA KATSURO
IPC: G02B6/44
Filed: 1988-04-30
Abstract: PURPOSE:To sense the current accurately without influence of noise by furnishing a sensor for photo-current, which flows in a conductor between the undersurface of an insulator body and a conductor clamp, through an optical fiber, and providing a shield member at the lower part of the insulator. CONSTITUTION:Magnetic field generated around a conductor 9 by the current flowing in it is converted into optical signals by a photo-current sensor 13 installed between the bottom of an insulator body 1 and a conductor clamp 3. As this sensor a Faraday element is used such as YIG, BSO which has a function to convert current into optical signal, in which the current is sensed through utilization of the rotation of a light deflection surface due to magnetic field. The optical signal sensed is taken out from the top of the body 1 through an optical fiber 5 incorporated in the body 1. A shield member 14 is furnished to prevent completely the influence of magnetic field due to the current flowing in the other phases. This enables precise sensing of current.

Abstract: PURPOSE:To facilitate image composition by supplying the slice level of a video signal in a memory to an image composing circuit with an external input signal and superimposing the slice level upon an external output as a display signal. CONSTITUTION:When an image of a mountain 2 is superimposed while an image of a tree 1 is stored in the memory, the image of the tree 1 is cut. When conditions of the cutting are determined by using brightness, the range of the brightness is divided and a part which is lower in brightness than a properly selected slice level is cut while a part which is higher than the slice level is left. The value of this slice level is operated to leave only a specific part in the image, i.e. only the tree 1 in this case, and the image of only the tree 1 is superimposed on the image of the mountain 2 to obtain a desired image. Then the slice level of the cutting is displayed on the screen as characters. Consequently, the operation is easily performed.

Title: Heat resistant elastic roll and manufacture thereof
IPC: D06C15/06
Filed: 1992-04-02
Abstract: PURPOSE:To increase surface hardness with mirror finished surface and to use it in a high temperature, with high nipple pressure and high speed revolution by giving a thermal expansion coefficient increasing step by step with three layers or more from the inorganic fiber reinforcement layer of an inner surface layer toward the organic fiber reinforcement layer of an outer surface layer into a fiber reinforcement resin sleeve. CONSTITUTION:A fiber reinforcement resin sleeve 2 is brought into adhesion to a metal roll core 1. A fiber reinforcement layer is made by winding up a fiber for reinforcing in a cylindrical layer shape in advance and soaking and hardening a liquid resin so that the outer periphery of a metal roll core 1 can be an inorganic fiber layer 21, an outer periphery layer be an organic fiber layer 23 and an intermediate layer be the inorganic or organic fiber layer 22 consisting of plural layers. In this case, a fiber content and a wind up tension are adjusted so as to enlarge a thermal expansion coefficient step by step from the metal roll core 1 toward the outer layer surface in order to relieve a stress acting to the interface generating by the difference of a thermal expansion caused between a hardening time and a high temperature using time of respective layers. It is desirable that a first layer is the reinforcement layers of a glass, carbon and the like and the outer surface layer is a fiber effective to the prevention of the scattering of a fragment.

Title: Multi-stage output touch sensor
Inventor: FUJIWARA YUJI
IPC: G01L1/20
Filed: 1986-05-14
Abstract: PURPOSE:To achieve a detection of a pressure value for a desired number of stages with a simple circuitry, by laminating sheets of pressure conducting rubber different in the pressure/electric resistance characteristic across the thickness at the same position through N or more sheets (N>=2) of electrode plates. CONSTITUTION:In a touch sensor 10, for example, two sheets of pressure conducting rubber 121 and 122 are interposed at the same vertical position between three sheets of electrode plates 111-113, which are connected to an on/off detection circuit 13. The rubber 121 is switched ON at a pressure of P0 while the rubber 122 done at a pressure of P1 and hence, when a pressure P is applied, three pressure states -- P<P0, P0<P<P1 and P1<P -- will be detected. In other words, when N sheets (N>=2) of pressure conducting rubber are used, N+1 patterns of pressure state will be detected. Here, as the pressure P0 or P1 is determined by the quality of the rubber, the proper selection of rubber enables the setting of a desired pressure detection range. Besides, in the structure, the detection circuit can be simplified because only detection of ON or OFF state is required.

Title: Conductive paste for aluminum nitride sintered body
IPC: H05K1/09
Filed: 1992-04-02
Abstract: PURPOSE:To provide a circuit board of high electric insulation and heat conductivity by forming a conductor layer having stable bonding strength on the surface of an aluminum nitride board. CONSTITUTION:Metal powder such as Mo, W is used as a principal component forming a conductor paste. The difference in the ratio of thermal expansion is reduced between the conductor paste and aluminum nitride of a board, and a condition of stable connection is achieved. When 1.0-30wt.% of siliceous glass or silicate glass is added to the metal powder, the melting point of the conductor paste is lowered, while the fluidity is improved, and the sintering condition will be smoothed. When SrO is added to the pieces of glass, the bonding strength to an aluminum nitride sintered body is improved. The amount of SrO to be added is set to 50-70wt.%. Since the conductor paste contains the glass of low melting point of 1200-1300 deg. C, a paste on the board has a liquid phase, and high fluidity and bonding strength. The content of oxides is less, while the content of the metal powder is higher compared to a conventional paste, and the conductivity is thus improved.
