Patent JP-H11171663-A (JP)
Title: Production of ceramic porous body
Inventor: MIYAGAWA NAOMICHI
IPC: D06M101/16
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain a porous body having uniform through pores orientated in one direction and a fixed porosity by using an organic fibrous substance having the surface coated with a metal magnetic material as a pore forming material. SOLUTION: An organic fibrous substance (e.g. nylon fiber) coated with a metal magnetic material (e.g. Ni, Fe or Co) is orientated in one direction on the surface of a porous substrate (e.g. gypsum board). A slurry containing a ceramic material (e.g. mixed powder of three kinds of silica, alumina and magnesia) is applied to the porous substrate to give a molding product having the magnetic material-coated fibrous substance orientated in one direction in the ceramic. The ceramic is heat-treated and the pore forming material is removed to reinforce the ceramic. The organic fiber 1 coated with the metal magnetic coated layer 6 is subjected to close packing and orientated through a ceramic coated layer 2 which is the same kind as that of a matrix or adapted to the matrix.  The pore diameter is determined by a diameter (R) 3 of the fiber 1 and the solvent pore density = porosity is decided by the thickness (T) 4 of the coated layer 2.

Title: Optical recording medium and optical recording and reproducing device
Inventor: MIYAMOTO JIICHI
IPC: G11B7/24091
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To effectively arrange address information by arranging prepits so as to be positioned on virtually prolonged lines of the boundary parts between groove parts and intergroove parts and at both sides of the left and the right with respect to the center lines between the groove parts and the intergroove parts and so as not to simultaneously exist at the both sides of the same positions between the groove parts and the intergroove parts to suppress a track offset low. SOLUTION: A groove part 84 and a land part 85 are alternately arranged and recording marks 81 are recorded in both areas of the parts. In a prepit part 83, grooves are not formed and prepits 82 are arranged on prolonged lines of boundaries between the land parts 85 and the groove parts 84. Then, in a first prepit part 831, prepits 82 are arranged at upper sides with respect to center lines of the land parts 85 and in a second prepit part 832, the prepits 82 are arranged at lower sides with respect to center lines of the land parts 85. Consequently, when a light spot 21 scans on the land parts 85, only the pits of one side of either sides are reproduced.

Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To easily form a high-reliability light shielding structure without great increase in the process by providing a diamond-like C film least above a light shield requiring region. SOLUTION: After forming photo diode elements and NPN transistor elements, a first silicon oxide insulating film 90 is formed on the entire surface, metal electrodes 100 of the photo diode elements and NPN transistor elements are made from a first metal layer, a diamond-like C film 140 of about 1 μm is formed on the entire wafer surface by the CVD, regions on photo detectors are removed by the RIE method, a wiring is formed from a second metal layer 120, and a silicon oxide protective film 130 is formed, thereby obtaining a desired structure.

Title: Cache system
Inventor: MATOBA TSUKASA
IPC: G06F9/38
Filed: 1993-12-27
Abstract: PURPOSE:To improve the performance of branch instruction execution by a CPU. CONSTITUTION:A cache controller 303 registers a branch destination address in an entry of a tag memory 301 corresponding to a cache line when the branch instruction in the cache line of an instruction memory 302 is executed. When the instruction of the cache line is fetched again, the cache controller 303 inspects the branch destination address registered in the entry of the tag memory 301 corresponding to the cache line, and reads an instruction group including the instruction of the branch destination address out of main storage and stores it in the instruction memory 301 prior to the execution of the branch instruction. Therefore, a determining process for the branch destination address and a cache refilling process can be started prior to the execution of the branch instruction to improve the CPU performance.

Title: Air conditioner
Inventor: IWASAKA TOSHIHIKO
IPC: F24F13/20
Filed: 1993-12-28
Abstract: PURPOSE:To provide an air conditioner capable of preventing dew from being formed on the outside of a ceiling part of a case. CONSTITUTION:Since a ceiling part 23 of a case and an upper end 5a of a refrigerant heat exchanger 5 have the shapes matched to each other, primary air taken from a suction port is not displaced from an air passage through which it passes the refrigerant heat exchanger 5, and it is not accumulated between the ceiling part 23 and the upper end 5a of the refrigerant heat exchanger. Accordingly, dew is difficult to be generated on the outside of the ceiling part 23. Moreover, since a hollow 29 is formed on the ceiling part 23 along the refrigerant heat exchanger 5, the outside and the inside of the ceiling part 23 are sufficiently insulated from each other by the hollow 29, so as to prevent dew from being formed on the outside of the ceiling part.

Title: Production of satin white
Inventor: NOGUCHI KENJI
IPC: C01F7/76
Filed: 1991-12-13
Abstract: PURPOSE:To provide satin white not containing coarse particles, containing an extremely reduced amount of quartz particles and not causing the generation of streak defects by dissolving calcined lime having a specific particle diameter and subsequently reacting the suspension of the produced hydrated lime with aluminum sulfate. CONSTITUTION:In a method for producing satin white for coatings by dissolving calcined lime in water for the production of the suspension of the hydrated lime and subsequently reacting the hydrated lime with aluminum sulfate, the particle diameter of the calcined lime is controlled to a range of 0.1-5.0mm. When the particle diameter of the calcined lime exceeds 5.0mm, the calcined lime is not suitable, because the remaining of many dissolution residues, the generation of clogging troubles and the increase of coarse particles in the particle size distribution are caused at the step of filtration after the calcined lime is dissolved in water and before aluminum sulfate is added. When the particle diameter of the calcined lime is smaller than 0.1mm, the contamination of quarts having a particle diameter of 75-100mu and streak defects may be caused.
