Title: Manufacture of chemical-containing plastic molded part
Inventor: SAITO HACHIRO
IPC: A61K8/00
Filed: 1985-12-30
Abstract: PURPOSE:To hot-melt and mold granular plastic in a mold by a method wherein an adequate amount of the chemical-containing granular plastic is packed to a mold made of material which is not heated by high frequency electromagnetic field and does not shield electromagnetic field, and after that high frequency electromagnetic field is applied to said mold. CONSTITUTION:First, EVA (ethylene-vinyl acetate copolymer) is used to prepare chemical-containing granular plastic by pregnating plastic material with a suitable chemical. On the other hand, a mold for a desired product is made of a material which is not heated by high frequency electromagnetic field. Secondly, said chemical-containing granular plastic is packed in the mold. Thirdly, the covered mold is placed in a high frequency heater in order to hot-melt only the chemical-containing granular plastic in the mold by applying high frequency electromagnetic field to the mold. Because the chemical-containing granular plastic in the mold is heated from its interior in a short time, the temperature of the product does not go higher than the necessary temperature. Accordingly, the chemical in the plastic scarcely volatilizes and the plastic can be molded without causing a change in property or a deterioration due to heat.

Title: Method and apparatus for applying highly viscous material
Inventor: HATAKEYAMA YUTAKA
IPC: B05C1/02
Filed: 1992-11-09
Abstract: PURPOSE:To provide a method and apparatus which can efficiently apply a given amount of a highly viscous material. CONSTITUTION:A transcription pin 5 exposed from a guide plate 4, after the end part of the pin 5 being soaked in an adhesive (highly viscous material) 2a, is pulled back from the guide plate 4 by a given distance, and the adhesive 2a exposed from the guide plate 4 is wiped away with a scraper 7. In this way, the given amount of the adhesive 2a is left on the end face of the pin 5. The pin 5 is exposed again so that the given amount of the adhesive 2a left on the end face of the pin 5 is applied on a surface to be coated. By keeping the length L, by which the pin 5 is pulled back from the end face 4b of a guide hole 4a, constant, the amount of the adhesive 2a left on the end face 5a of the pin 5 is adjusted constant. Since the given amount of the adhesive 2a can be left on the end face 5a of the pin 5 with the end face 5a of the pin 5 oriented downward, the adhesive 2a can easily be applied vertically or horizontally to the surface to be coated.

Filed: 1992-11-09
Abstract: PURPOSE:To prevent the flame from running away outwardly even if the gas to be measured explodes by providing flame arresters respectively in the suction pipe and the discharge pipe for the gas to be measured. CONSTITUTION:The gas to be measured which has passed through a filter 39 is sucked in from one end of a suction pipe 35, and filled in a detection chamber 46 via flame arrester 48a, so that its oxgen content and the like are detected by means of a sensor unit 20. The gas is passed through a discharge pipe 36 via a flame arrester 48b, and discharged into a furnace through a chamber 38. The suciton tube 35 penetrates through a heat insulating block 45 via a heat conducting block 31a. Since these are kept at a high temperatue by means of a cartridege heater 10 and a thermister 34, blocking due to moisture condensation is unlikely to take place. Even if the gas is imflammale so that it explodes in the detection chamber 46 and the back flow of the flame takes place in the suction pipe 35 and the discharge pipe 36, the running-away of the flame can be prevented by flame arresters 48a and 48b. Furthermore, the outward runing-away of the flame can be prevented by flame arresters 48c to 48e.

Title: Fixing structure of friction/abrasion testing pin
Inventor: ABE YUTAKA
IPC: G01N33/38
Filed: 1991-11-14
Abstract: PURPOSE:To obtain a fixing structure of a testing pin which is hard to break with superior durability even under high speed heavy load by so arranging as to receive the pressure of a pressurizing member at the cylindrical side face of the pin set inside a pin holding part. CONSTITUTION:A pin holding part 12 is projected from a fixing tool 11 made of silicon nitride. The inside surface of the pin holding part 12 is formed cylindrical and the outer peripheral surface thereof is tapered. The pin holding part 12 is constituted of two separate blocks. A pressurizing member 13 is arranged concentrically in the periphery of the pin holding part 12, imparting tightening pressure to a testing pin 14 of the same material as the fixing tool 11, i.e., silicon nitride, in a direction of an arrow A. The pressing force is thus added to the cylindrical side face of the pin. Since the pressing force is added to a surface with some width, the stress is never concentrated on one point, and the testing pin 14 is prevented from breaking. If there is no problem in the rigidity on the testing system side, metallic material may be used for the fixing tool 11 and pin holding part 12.

Filed: 1989-11-16
Abstract: PURPOSE:To prevent an original and a photosensitive material from being deformed or damaged and to obtain a clear image by specifying the specific surface resistance of a shielding member to be moved from an original platen aperture part. CONSTITUTION:The close contact type exposure device having a photosensitive material tray to be relatively moved from the original platen having an aperture part and the shielding member to be moved from the original platen aperture part is constituted so that the specific surface resistance of the shielding member is <= 1.0 X 10<12>OMEGA.cm, preferably <= 5.0 X 10<11>OMEGA.cm, at the time of normal temperature and humidity conditions in order to prevent the generation of electrostatic charge on the original. Thereby, it is necessary to constitute at least the face being in contact with the original out of the shielding member of a conductive member. Therefore, conductivity is imparted to the whole shielding member or the surface of the shielding member or the whole surface of the shielding member is converted with a conductivity imparting sheet or the like. When the surface of the shielding member is rugged, the sliding property of the shielding member on the surface of an original film can be improved and the original film can be prevented from being deformed or damaged due to a hitch.
