Abstract: PURPOSE:To simplify the alignment operation of an optical element in an optical system and to reduce the cost in the production of an optical element using a forming mold having a specific intermediate mold, by making a difference between the heating rate of an upper mold and the intermediate mold and the heating rate of a lower mold. CONSTITUTION:The mold for forming the optical element for the present process is composed of an upper and a lower molds 11 and 12 slidably placed in a sleeve mold 13 and an intermediate mold 14 positioned between the upper and the lower molds and also slidably placed in the sleeve mold 13. The intermediate mold 14 is provided with two or more forming surfaces and with a space 18 between the intermediate mold and a part of the sleeve mold 13 which is uninfluential to the optical forming surface. Glass raw materials 15, 16 are supplied between the upper mold 11 and the intermediate mold 14 and between the intermediate mold 14 and the lower mold 12, respectively. The upper mold 11 and the intermediate mold 14 are heated with a heater 17 and heaters built in the upper and the lower molds at a prescribed heating rate to a temperature near the softening point of the glass and thereafter the lower mold 12 is heated to a temperature near the softening point at a prescribed heating rate. At the same time, the materials are pressed with the upper mold 11 and the lower mold 12 to form the glass raw material 15 with the upper mold 11. A part of the material 15 is passed through the space 18, extruded to the side of the lower mold 12, fused with the raw material 16 and formed with the lower mold 12 to obtain an optical element 26 having an optical axis alignment part 27.

Title: Production of polyvinyl acetate-based emulsion and its stabilization
Inventor: ADAKA TOSHIAKI
IPC: C08K13/02
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyvinyl acetate-based emulsion, hardly increasing viscosity in polymerization, and further, having good viscosity stability in storage. SOLUTION: This polyvinyl acetate-based emulsion is produced by emulsion polymerization using an acetoacetylated polyvinyl alcohol in the presence of viscosity lowering agent comprising (1) one or two kinds of compounds selected from sulfite, bisulfite, metabisulfite and thiosulfite or in the presence of these compounds together with (2) ethylene diamine tetraacetic acid or ethylenediamine tetraacetate. Since increase of viscosity in polymerization is suppressed thereby, emulsion excellent in viscosity stability and handleability is obtained. The viscosity stability is further improved by adding a storage stabilizer comprising the above (1) and (2) to the emulsion after polymerization. The storage stabilizer is effective for polyvinyl acetate-based emulsion containing acetoacetylated polyvinyl alcohol produced by an arbitrary method.

SOLUTION: A primary feeder is composed of a plurality of copper pipes 6 connected to each other. Approximately cylindrical female connector 8 and male connector 9 are screwed into female screw parts 6a and 6a on both the ends of the copper pipe 6 with the male screw part 8a of the female screw 8 and the male screw part 9a of the male connector 9 respectively.

Title: Thermal recording material
Inventor: TERAMURA KAORU
IPC: G11B7/24047
Filed: 1989-12-27
Abstract: PURPOSE:To enhance heat efficiency and to control the temp. of a recording layer accurately corresponding to the temp. of a planar heater by integrating a recording medium utilizing the optical change accompanied by a change in a degree of crystallization in recording with the planar heater. CONSTITUTION:A recording layer 1 composed of a crystalline polymer has a planar heater 2 and an image is formed to the recording layer by scanning the surface of the recording layer 1 by a thermal recording head 3 or a heat pen 4. When the recording layer 1 is heated to the m.p. of the crystalline polymer and quenched, the crystalline polymer is solidified in a state low in a degree of crystallization to take a transparent high transmissivity state and becomes a dark state under crossed Nicols. When the recording layer 1 is heated to the m.p. of the crystalline polymer or higher and cooled gradually, the crystalline polymer is solidified in a state high in a degree of crystallization to take a cloudy low light transmissivity state to become a bright state under crossed Nicols. By integrating the recording layer 1 and the planar heater 2 as mentioned above, easy writing and erasure becomes possible and heat efficiency is high because both of them are integrated and the temp. of the recording layer 1 can be controlled so as to accurately correspond to the temp. of the planar heater 2.
