Abstract: PURPOSE: To enhance long term light resistance of a dye image produced, and to prevent yellow staining of an unexposed area, by introducing a group having a specified oxidation prevention function in an optional site of the molecular structure of the coupler to be used for a color photographic material.  
     CONSTITUTION: To a silver halide emulsion layer or layers adjacent to this layer in an amount of 10 to 100 g/mole of silver halide is added a coupler having a group capable of preventing oxidation represented by the formula in which R 1  to R 4  are each optionally substituted alkyl, alkenyl, aryl, or cycloalkyl, or (AX n ) m Cp; Cp is a residue of cyan, magenta, or yellow coupler; A is an optionally substituted divalent aliphatic residue; X is a divalent group; m and n are 0 or 1; and at least one of R 1  to R 4  is (AX n ) m Cp. This addition permits color fog to be eliminated, and discoloration prevention effect and yellow stain prevention effect to be enhanced.

Title: Production of copolymer
Inventor: NAKADA MASAHIDE
IPC: C08F2/00
Filed: 1984-04-05
Abstract: PURPOSE:To produce a copolymer of an MW<=10,000 in good yields without any dispersant, by feeding monomers to a reaction tank in a specified manner, in effecting the precipitation polymerization of an aromatic vinyl monomer and maleic anhydride. CONSTITUTION:The copolymerization of aromatic vinyl monomer (e.g., styrene) with maleic anhydride is carried out by using a solvent in which the monomers are soluble but the formed copolymer is not soluble (e.g., benzene or toluene) as a polymerization medium in the presence of a radical initiator such as azobisisobutyronitrile. At this time, from dropping tank I , a mixture comprising the aromatic vinyl monomer, the polymerization initiator and the solvent is added to the reaction tank containing the solvent at a constant rate, and on the other hand, from dropping tank II, maleic anhydride (or its solvent solution) is added to the reaction tank in an amount half to a tenth of the total amount of addition, for each time, while the reaction mixture is being polymerized with gentle agitation (at about 80-200 deg.C for about 0.5-10hr).

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a melt spinning unit so designed that a specific air flow cutting plate is set up right under a device to cool a spun filament yarn so as not to cause yarn fluctuations before an oiling roller even in the case of melt spinning of a filament yarn >=100 denier in fineness.

Title: Oxygen sensor
Inventor: SUEMASU TATSUO
IPC: G01N27/41
Filed: 1988-03-23
Abstract: PURPOSE:To obtain an oxygen sensor capable of measuring the accurate concn. of oxygen and generating no metal or NOx gas, by constituting a resin stem of a resole type phenol resin. CONSTITUTION:An oxygen sensor is constituted by embedding a pin 2 in a resole type resin stem 1 to fix the same to said molded stem 1. The upper end of the pin 2 has a protruding height of about 5mm and an oxygen sensor element 3 is mounted thereon in a suspended state. Since a resole type resin is of a self-curing property and a curing agent is not used like a novolac type phenol resin, said resin generates no ammonia and is not too inferior to mechanical strength and electric properties. Therefore, this oxygen sensor can measure the concn. of oxygen accurately, because no ammonia is generated from the resin stem.

Title: Method of bending external lead and forming device using the method
Inventor: NISHIZAWA SHINICHI
IPC: B21D5/01
Filed: 1990-03-16
Abstract: PURPOSE:To realize more accurate external lead bending by bending an external lead with a punch roller by pushing a roller holder and forming the base section of the bent lead by pressing the base section with a pressing section. CONSTITUTION:A pressing section 22 which presses the shoulder section of an external lead 10 is installed to the side of a roller holder 20 facing the lead 10 and the lead 10 is pressed with a punch roller 18 and, at the same time, the shoulder section of the lead 10 is pressed with the section 22. The angle of the outside wall surface of the section 22 which comes into contact with the lead 10 is set so that the lead 10 can be pressed by both the wall surface of the section 22 and a bending die 16 when the roller 18 completes the bending work. Therefore, since the external lead 10 is bent by means of the punch roller 18 and, at the same time, pressed by means of the pressing section 22, the spring back, etc., of the lead 10 can be suppressed and more accurate bending can be realized.

Title: Structure of phase shift mask and preparation thereof
Inventor: ZUN SOKU RI
IPC: G03F1/36
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To improve the resolution by providing a translucent substrate, a phase transition layer formed by having a translucent region on this substrate and an auxiliary light shielding pattern formed on the phase transition layer between these translucent regions. SOLUTION: The auxiliary light shielding pattern is not formed between two isolated patterns of the phase shift mask constituted by forming the translucent region apart the same spacing in the perpendicular and horizontal directions on the phase transition layer 12 (when the light intensity is assumed not to exceed the threshold value between the two isolated patterns) and the auxiliary light shielding pattern 14 is formed near the position nearly the equally spaced from the respective isolated patterns of the phase transition layer between the four isolated patterns (light shielding regions). At this time, the auxiliary light shielding patterns 14 is formed in to a regular quadrangular shape. As a result, the formation of the unnecessary patterns is prevented by offsetting the interference (-) amplitude. The arrangement of the auxiliary light shielding patterns in corresponding to respective forms is possible even when the horizontal and perpendicular distances between the adjacent isolated patterns vary. The execution of a storing exposure stage is thus possible.

Abstract: PROBLEM TO BE SOLVED: To obtain a synthetic quartz glass member which can efficiently transmit fluorine excimer laser light and is not damaged to lower the transmittance of the laser light by controlling the contents of hydroxy groups and fluorine atoms to specific values, respectively, and eliminating chlorine atoms. SOLUTION: This synthetic quartz glass member which has a hydroxy group content of 1-50 ppm and a fluorine content of 100-1,000 ppm and does not contain a chlorine atom is obtained by mixing a silane compound not containing a chlorine atom with a fluorine compound not containing a chlorine atom and then feeding the mixture into an oxyhydrogen flame to form the porous silica sintered product. Therein, the silane compound not containing the chlorine atom and the fluorine compound not containing the chlorine atom are mixed in a fluorine atom/(silicon atoms+fluorine atoms) ratio of 5-70 atom %, and the silica sintered product has a bulk density of 0.3-0.6 g/cm3. The glass member preferably has a birefringence of <=2 mm/cm.  When used as an optical member for light having a wavelength of <=200 nm, especially excimer laser light (wavelength of 157 nm), the synthetic quartz glass member can efficiently transmit the light and resist to its employment for a long period.
