Title: Solid retouching utensil
Inventor: TAKAHASHI YASUHIRO
IPC: C09D10/00
Filed: 1990-08-24
Abstract: PURPOSE:To obtain a solid retouching utensil which has an advantage as a solid and provides a coating film with high strength and hiding power by mixing a base material selected among specified (co)polymers, a white pigment, and hollow or porous particles. CONSTITUTION:A solid retouching utensil which contains a base material that is solid at ordinary temperature and selected among a polybutylene, a butylene copolymer, a hydrogenated polyisoprene, and a hydrogenated isoprene copolymer; a white pigment (titanium oxide is most desirable from the viewpoint of hiding power); and hollow particles and/or porous particles (e.g. glass microbaloons made of borosilicate glass or silica, spherical porous silica or spongy nylon powder). While conventional erasers composed mainly of volatile solvents have the shortcoming of lacking in quickness since rewriting is possible only after the completion of drying, this retouching utensil enables rewriting quickly. Because of the incorporation of the hollow or porous particles, it can form a film hard to flow even when rubbed with the finger, etc., and it has a sufficient hiding power even if the amount of the white pigment in the film is small.

Title: File transfer system
Inventor: YAMAMOTO SHIYUUKO
IPC: G06F12/00
Filed: 1989-09-01
Abstract: PURPOSE:To shorten the file transfer time by performing the transfer of data between plural terminal equipments and a TC in time division and with the prescribed sections. CONSTITUTION:When the transfer of file is informed from a terminal equipment 14-2 while a part b-1 of a file 1 is transferred between a terminal equipment 14-1 and a TC, the state of the file under transfer is stored in a file control memory 11. Then the contents b-2 and b-3 of the file data under transfer to the equipment 14-1 are saved to a terminal control memory 13. Thus the file is transferred to the equipment 14-2. When a request is received from the equipment 14-1 for the next data under transfer, the state of the file under transfer is restored out of the memory 11. Then the contents b-2 and b-3 which are under transfer to the equipment 14-1 from the memory 13 are restored. Thus the transfer of the file can be carried out successively from the preceding transfer. As a result, the file transfer time is shortened.

Abstract: PURPOSE:To exactly detect the volume of oil by limiting the floating region of the float of an oil amt. detecting means to a range where the float does not come into contact with an oil case. CONSTITUTION:The floating region of the float is so limited that the float 31 of a detecting means 30 does not come into contact with the bottom part 7a of an oil pan 7 even when a liquid level falls and oil replenishment is started. The means 30 is, therefore, so constituted that its lever 50 collides against a stopper 200 to provide a spacing X even when the oil runs out completely. The contact part 51 of the means 30 comes into contact with the stopper 200 when the oil level rises to attain a set level. The rotation thereof is then limited and the spacing Y is provided between the means 30 and the wall surface 7b of the oil pan 7. The non-operation of the float by the viscosity of the oil is prevented in this way and the exact volume of the oil is detected.
