Filed: 1989-02-15
Abstract: PURPOSE:To obtain a lined pipe prevented from increase in water pH value at the initial stage of water passage, increase in the amount of soluble Al and the surface uncure of cured mortar by lining the inner surface of a pipe with a lining material comprising a specific binder, sand and water followed by curing in a humidified state. CONSTITUTION:(A) A total of 100 pts.wt. of (1) 85-98 pts.wt. of a binder comprising (a) 85-99 pts.wt. of alumina cement with the molar ratio CaO/Al2O3>=1 and (b) 15-1 pts.wt. of potentially hydraulic noncrystalline silica of pH <=8 (e.g. microsilica), (2) 15-2 pts.wt. of an inorganic expansive agent (e.g. calcium sulfoaluminate) >=2500m<2>/g in Blaine specific surface area, (B) 0.1-5 pts.wt. of a water reducing agent (e. g. hexametaphosphoric acid), (C) 100-300 pts.wt. of sand, and (D) water, are kneaded so as to be <=25 deg.C in the temperature just after kneading, thus obtaining the objective lining material >=200mm in 15-times tap flow value. Thence, the inner surface of a pipe is fed with this lining material followed by application of a centrifugal force of 50-70G for >=5min to make a centrifugal forming to effect lining said inner surface. The resultant pipe is then put to primary curing at <=25 deg.C under humidifying conditions of >=60% RH, and the resultant surface is uniformly abraded, and the pipe is then put to secondary curing at normal temperature and air-drying conditions for >=2 days.

Title: Construction to prevent heat radiation loss from bath tub
Inventor: MASUGUCHI YOSHITSUGU
IPC: F24H9/00
Filed: 1985-02-25
Abstract: PURPOSE:To improve thermal insulation function of a bath tub providing a valve which is installed to the opening of the water recycling upper pipe of a bath tub and the lid of which is provided on the valve on the side of the bath tub for opening and closing the valve and supporting elastically the valve lid by means of an elastically displacable body made of a two-directional shape memory alloy. CONSTITUTION:The lid 6 of a valve installed at the opening 5 of the upper water recycling pipe 3 of a bath tub 2 on the side thereof is elastically supported between stays 10 and 10 provided respectively on a cylindrical body 9 of the lid 6 and a support cylinder 8 on the side of the pipe 3 by extending in tension an elastically displacable body 7 made of a two-directional shaper memory alloy. The elastically displacable body 7 contracts and urges the lid 6 to the opening 5 by its spring action until it reaches a specified temperature, blocking the back-flow from a bath tub 2 to a bath heating unit 1. When temperature of hot water rises to a specified temperature, the elastically displacable body 7 expands in length and opens the lid 6. Next, when, after the heating is completed, the hot water temperature drops below the specified temperature to another specified temperature, the elastically displacable body 7 contracts to close the lid 6. The thermal insulation function of the bath tube is thereby improved.

Abstract: PURPOSE: To prevent the driving of a developer applying means, when a photoreceptor is driven to reversely rotate by disposing a coupling having a prescribed backlash corresponding to a prescribed rotation angle at which the photoreceptor is driven to reversely rotate, in a power transmitting mechanism. CONSTITUTION: An electrically driven motor 11 is driven to reversely rotate, so that a first gear 152 constituting the coupling gear 150 of a second power transmitting mechanism 13 is driven in an opposite direction. But engaging projecting parts 155 and 156 constituting the coupling 154 and engaging projecting parts 157 and 158 provided on the end surface of a second gear 153 have a backlash by the prescribed rotation angle corresponding to the reverse rotary driving quantity of the photoreceptor 2, so that from the second gear 153 to a gear to be driven in the second power transmitting mechanism 13, reverse rotary driving can not occur. Therefore, even if the electrically driven motor 11 is driven to reversely rotate the photoreceptor 2, for the reverse rotary driving of the photoreceptor 2, the developer applying means 52 is never driven to reversely rotate.  Since a one-way clutch 190 is disposed between an intermediate gear 170 and a fixed gear 171, a roller is never driven.
