Patent JP-H02179407-A (JP)
Title: Measuring device of flatness
Inventor: SUZUKI MASANE
IPC: G01B11/24
Filed: 1988-12-29
Abstract: PURPOSE:To prevent noise in a projected image of interference fringes by a method wherein a plurality of laser lights are superposed and applied as a coherent light. CONSTITUTION:When laser light sources 1 and 2 are driven, laser lights L1 and L2 are superposed through a collimator lens 3 to be a parallel light and this light falls as a coherent light L on the incident surface 4a of a datum prototype 4 at an angle theta. By the coherent light L falling obliquely, interference fringes due to an optical path difference, i.e. a gap 6, between a reference surface 4b of the prototype 4 and a surface 5a to be measured of a substance 5 to be inspected are generated and projected on a screen 7. In detail, a light LA passing through the prototype 4 and the reflected light of a light LB passing through the prototype 4 and the gap 6, being reflected on a surface 5a to be measured and proceeding toward the reference surface 4b are superposed and the interference fringes corresponding to nonuniformity in the opening of the gap 6 are generated by the optical path difference between the two lights. Since the distance of coherence of the coherent light L is short due to the superposition of the laser lights L1 and L2 in this constitution, no interference fringes are generated by the optical path difference due to the thickness of the substance 5 to be inspected, which is larger than the opening of the gap 6, and the thickness of the prototype 4.

On the basis of the measured reflected wave information, the region of generation of a locally deteriorated water tree is detected.  Besides, the degree of deterioration of the region of generation of this water tree is evaluated, on the basis of the quantity of residual charge measured when the AC voltage is applied, and the region of generation of the deteriorated water tree found by the method.

Title: Conversion of waste thermosetting resin into oil
Inventor: NANBU MASAHIRO
IPC: C10G1/10
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain in a high efficiency an oily product useful as a fuel oil by efficient thermal decomposition by heating a waste thermosetting resin in an aromatic hydrocarbon-based liquid medium having a specified boiling point. SOLUTION: A waste thermosetting resin is heated and decomposed by a contact with a liquid medium comprising an aromatic hydrocarbon having a boiling point of 250 deg.C or higher or a hydride thereof. The waste thermosetting resin includes an unsaturated polyester resin, a phenol resin, a thermosetting polyurethane and an epoxy resin. This method is suitable especially for a treatment of a waste thermosetting resin such as a fiber reinforced thermosetting resin and a glass fiber reinforced unsaturated polyester resin. Typically, a waste resin of an appropriate size is introduced in a thermal decomposition tank, followed by adding the liquid medium in an amount enough to soak the whole resin therein, and heated preferably at 300-400 deg.C. A vapor product generated by the thermal decomposition is condensed to obtain a combustible oily product.  Alternatively, the vapor product is brought into contact with a solid catalyst for catalytic cracking to obtain a combustible low boiling point oily product.

Title: Method for improving silver recovery rate in electrolytic refining of copper
Inventor: ANDO KOJI
IPC: C25C1/20
Filed: 1994-12-27
Abstract: PURPOSE: To separate and recover Ag in an anode at a high recovery rate by properly controlling the Cl ion concn. in an electrolytic solution and the temp. of the solution at the time of producing electrolytic copper with an electrolytic refining method using crude copper as the anode. CONSTITUTION: In this method, consumable anodes 10 each made of crude copper contg. Ag, etc., as impurities and cathodes 20 each made of a high purity electrolytic copper thin sheet are alternately arranged in an electrolytic tank and an electrolytic solution 20a is supplied into the electrolytic tank through a solution supply pipe 30. Thereafter, the Cl ion concn. in the electrolytic solution 20a contg. copper sulfate and the temp. of the solution 20a in the vicinity of the lower end of each of the cathodes 20 are adjusted to 30 to 60mg/λ and <=55 deg.C respectively. Then, Cu of each of the anodes 10 made of crude copper is dissolved into the electrolytic solution 20a by passing current between the anodes 10 and the cathodes 20 and concurrently, high purity Cu is deposited on the surface of each of the cathodes 20.  At this time, Ag in the anodes 10 is converted into AgCl and since the solubility of AgCl in the electrolytic solution 20a is decreased at the time of lowering the temp. of the solution 20a, the formed AgCl is precipitated on the bottom of the electrolytic tank as electrolytic slime without depositing Ag on the cathodes 20. This electrolytic slime is separated from the electrolytic solution 20a and refined. Thus, Ag is separated and recovered from the anodes 10 as a noble metal in an excellent yield.

Abstract: PURPOSE:To improve the processing speed of character emphasis and to facilitate character conversion after outputting an emphasized character by expressing a character pattern after performing the character emphasis in a coordinate string on its contour line, and storing the coordinate string even after outputting the emphasized character. CONSTITUTION:The device is equipped with an emphatic width designation means 2 to designate the emphatic width of a character, an emphasis vector data generating means 3 to generate emphasis vector data in which the character pattern of the character after emphasis is expressed in the coordinate string of the inflection point of the contour line, and an emphasis vector data storage means 5 to store the emphasis vector data. When conversion such as magnification, reduction, rotation, and a quasi- field, etc., is applied to the character, and the character is outputted after applying the emphasis, the emphasis vector data is generated based on designated emphatic width after converting vector data in which the character pattern is expressed in the coordinate string of the inflection point of the contour line to the vector data expressing the contour line of the character pattern after character conversion with a character conversion means 4, and the emphasis vector data is outputted after being converted to data of bit pattern. In such a way, the processing time of the character emphasis can be shortened, which simplifies character conversion processing.

Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection nozzle 1 which is easy to machine and which is capable of preventing abnormal wear of a seat face 6. SOLUTION: A seat face 6 of a nozzle body 3 is partially composed of a seat member 7. The seat member 7 is arranged in the neighborhood around a portion which a seat part 4b of a needle 4 is to strike, out of the whole seat face 6. That is, a ring-like recessed part 3a is previously provided in an inverted conical surface of the nozzle body 3, and the ring-like seat member 7 is installed in the recessed part 3a to form a stepless, smooth seat face 6. The material forming the seat member 7 can maintain the hardness at the time of room temperature even when the material is subjected to combustion heat of an engine to increase the temperature. In this case, for example, ceramic can be used since this material is more excellent in wear resistance than the material constituting the whole of the nozzle body 3, at least at the time when the temperature is raised.
