Title: Method for molding resin composition
Inventor: MIYAKE SHINJI
IPC: B29C48/92
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of a coloring phenomenon and upgrade the thickness accuracy and the gas barrier properties by making the thickness of a resin composition to be obtained by extruding the composition from the gap of a die slit and a die satisfy specific conditions. SOLUTION: When a resin composition composed mainly of EVOH (an ethylene-polyvinyl acetate copolymer-saponified product) is extruded from a die and molded by melting, the thickness (T1) of the resin composition at the time of extruding it from the gap (T0) of a die slit and the die and casting it by a casting roll, is adjusted so that the thickness (T1) meets the conditions of the respective formulae: 0.05<T0<5.0 and 0.01<(T1/T0)<1.0. In the formulae, however, the units of T0 and T1 are mm. Thus it is possible to upgrade the thickness accuracy and the gas barrier properties without the occurrence of a coloring phenomenon, even when 10-500 ppm sodium in terms of atoms are added to the resin composition.

Title: Developer replenishing device
Inventor: YONEMORI TAKAHARU
IPC: G03G15/08
Filed: 1990-04-06
Abstract: PURPOSE:To effectively utilize a space at the lower part of a hopper part and to enlarge the capacity of the hopper part without making an image forming device main body large by making the rotational radius of a stirring part on the tip of a stirring member freely expandable/reducable and pressurizing and energizing the stirring member toward the inside surface side of the hopper part through an elastic member. CONSTITUTION:The stirring member member 22 is disposed so that the rotational radius thereof can be freely changed with respect to a rotary shaft 25. Besides, since the stirring member 22 is energized by the elastic member 26 and the stirring part 22b on the tip thereof is pressurized toward the inside surface side of the hopper part 21, the stirring part 22b of the stirring member 22 is rotated along the inside surface of the hopper 21. Therefore, the shape of the bottom part of the hopper part 21 need not be made a curved surface of a fixed radius and it can be formed to a box shape or the like. As the result, the space can be effectively utilized. Thus, the capacity of the hopper part is increased without changing the size of the device main body.

Abstract: PURPOSE: For improving metallic mask in strength and sizing accuracy, to crystallize a given portion of non-crystalline metal with electronic or laser beam and to etch said portion.  
     CONSTITUTION: A crystalline section 1 is made by applying electronic or laser beam in place of photo resist on a given portion of non-crystalline metallic plate 2. Said crystalline section 1 is almost vertical in thinkness direction and considerably higher than non-crystalline section 2 in corrosion resistance. When etching is made in the next process, therefore, no lateral etching takes place so that openings can be made precisely. Thus-manufactured metallic mask is offered for metallic deposition.

Abstract: PURPOSE: To selectively remove an organic lacquer layer by bringing the lacquer layer into contact with the non-charged component of plasma, formed by using a gas mixture composed only of CF4 and a specific volume of NO added to the mixture as an oxygen compound. CONSTITUTION: An organic lacquer layer 12 is formed on a conductive layer 11, and the non-coated part of the layer 11 is removed by an ordinary method. Finally, the lacquer layer 12 is removed by bringing the layer 12 into contact with the non-charged component of plasma formed in a gas mixture. The gas mixture composed only of CF4 and 55-75vol% NO added to the mixture as an oxygen compound. Therefore, only the lacquer layer 12 can be removed selectively, because the layer 12 can be etched off about 500 times faster than the polycrystalline silicon conductive layer 11.

Title: Freezing preserving method for embryo
Inventor: NOGAMI YOSHIRO
IPC: A61D19/00
Filed: 1990-04-04
Abstract: PURPOSE:To improve a freezing preservation effect of an embryo without needing an icing device and to save a labor for a work to transplant to an embryogeny animal by mounting a substance stabilized by mixing an ice crystal inducing agent in a carrier to the mouth part of a freezing preserving container or sealing a mouth part with the stabilized substance during the icing operation. CONSTITUTION:The mouth of a preserving container is sealed with a substance in which an ice crystal inducing agent, e.g. silver iodide, having an icing function is mixed in a carrier consisting of polyvinyl alcohol (PVA) and other adhesive at -3.0 deg.C or less. Or, the icing is effected in a way that the ice crystal inducing agent and the adhesive are mixed together and a part of the inside making contact with a preserving liquid is coated with the mixture. Since the ice crystal inducing agent is stabilized for use, the ice crystal inducing agent is not moved in freezing preserving liquid, and an adverse influence is not exercised on an embryos when the freezing preserving container is sealed with a substance mixed with PVA powder for stabilization, there is no need to heat-seal the container, and when other adhesive is mixed for stabilization to mount the mixture on the inner wall of the container, heat seal is used in combination. Even when stabilization is effected by using PVA powder serving as a carrier and other adhesive, performance of the ice crystal inducing agent is entirely prevented from lowering.
