Title: Preparation of molding dope of polyvinyl alcohol
Inventor: UNNO MITSUHIRO
IPC: C08F16/02
Filed: 1985-11-28
Abstract: PURPOSE:To prepare highly concentrated dope by a method wherein the level of solvent and the surface of the sediment layer of PVA (polyvinyl alcohol) particulate matter are made nearly parallel to each other and left to stand until the PVA particulate matter swells and turns transparent. CONSTITUTION:Solvent such as dimethyle sulfoxide or the like and PVA are put in a dope preparation vessel in such a manner that the surface of the sediment layer of PVA particulate matter is made parallel to the level of the solvent. In this case, the relationship between the solvent and the PVA satisfies the following formula: 0.5<=D/d<=5, where D represents the distance between the level of the solvent and the bottom of the dope preparation vessel (or the deepest part of the vessel, when the shape of the bottom is not flat) and (d) represents the distance between the surface of the sediment layer of the PvA particulate matter and said bottom. After that, the PVA particulate matter is left to stand so as to swell and turn too transparent to confirm its shape in order to obtain uniform dope.

Title: Carrier for developer
Inventor: FUNATO MASATOMI
IPC: G03G9/113
Filed: 1988-10-25
Abstract: PURPOSE:To prevent spenting, to improve durability and wear resistance and to form images of sharp quality over a long period of time by providing a coating layer of an org. silicon polymer on the surface of a carrier core material. CONSTITUTION:The coating layer of the org. silicon polymer is provided on the surface of the carrier core material. The org. silicon polymer has excellent film formability and is capable of forming a uniform and even coating layer at the time of forming the coating layer. The resin itself has adequately low surface energy and obviates the peeling and the generation of disintegrated particles in spite of the mechanical impact by long-term agitation operations. The life of the developer can thus be prolonged. Since the resin itself has high resistance, the increases of the film thickness of the coating layer to more than a required thickness is not needed and the resistance of the carrier itself is increased. The spenting is prevented in this way and the durability and wear resistance are improved. The images having the sharp quality are formed over a long period of time.

Abstract: PURPOSE:To obtain the title compsn. useful for making a communication cable covered with a highly expanded insulating material by compounding polyethylene with a specified amt. of a blowing agent comprising benzenesulfonylhydrazide and azodicarbonamide. CONSTITUTION:The title compsn. is prepd. by compounding polyethylene with 1.2-2.5wt.% blowing agent comprising benzenesulfonylhydrazide (OBSH) and azodicarbonamide (ADCA). The amt. of ADCA acounts for 10-40wt.% of the total amt. of the blowing agent, while the upper limit of the amt. of OBSH is 20wt.%. The total amt. less than 1.2wt.% gives an expansion ratio of only about 60%; that more than 2.5wt.% does not further increase the expansion ratio. The compsn., when expanded, shows an expansion of about 70% without generating cells with too large a diameter and gives a communication cable excellent in electrical properties and mechanical strengths.

Title: Printer
Inventor: MATSUMOTO TOMOYUKI
IPC: B41J2/32
Filed: 1986-11-12
Abstract: PURPOSE:To enable high quality printing irrespective of the type of recording medium, by providing a means for detecting the mounting of a thermal transfer ribbon and a means for varying the printing pressure through a drive means. CONSTITUTION:When printing is made onto a thermosensible paper 4, an arm 7 is rotated slightly in the direction of an arrow C by a solenoid 8 so as to rotate a shaft 2, thus moving a thermal head 1 in the direction separating from the thermographic paper 4. When the solenoid 8 is opened at this time, the head 1 is pressed against the thermosensible paper 4 by the energizing force of a spring 5, thus making a print onto the thermosensible paper 4. When printing is made onto a plain paper, a ribbon cartridge 40 is fixed and a thermal transfer ribbon 14 is inserted between the head 1 and the plain paper. Upon mounting of the ribbon cartridge 40, a projection 17a of a detection lever 17 is pressed so as to rotate the detection lever 17 in the direction of an arrow D. Consequently, a variable lever 15 secured to a detection shaft 16 rotates in the direction of the arrow D, thus increasing the tensile force of the spring 5. As a result, a clear print can be made even onto a plain paper which conventionally requires a large printing pressure.
