Abstract: PURPOSE: To improve the lower foundation of an existing structure by penetrating a casing in the horizontal direction from the inside of a shaft for operation, carrying out surplus earth in the casing, filling the casing with a powdery solidifying material and extracting the casing. CONSTITUTION: A head open type casing 2 is penetrated horizontally into an object foundation from the inside of a previously excavated shaft 31 for operation. A required number of the casings 2 are extended, and brought to specified length. Surplus earth in the casing 2 is carried out. A cap 4 is inserted into the casing 2, and the inflow of water from a front end is prevented. On the other hand, a drain body, in which the inside of a water-permeable housing body is filled with a powdery solidifying material, is inserted into the casing 2. The housing body is composed of a water-permeable material. The casing 2 is extracted, and the drain body is left at the specified place of the foundation, thus infiltrating pore water in the foundation into the drain body through the housing body, then solidifying the foundation by a reaction with the solidifying material.  The drain body is expanded at that time to break the housing body, and the foundation is loaded, thus promoting consolidation drainage.

Title: Lubricating device for thrust bearing
Inventor: YAMAGUCHI KATSUMI
IPC: F16C33/00
Filed: 1977-12-28
Abstract: PURPOSE: To prevent shortage of lubricating oil supply to a thrust bearing and a thrust bearing pushing up device by constituiting a lubricating device therefor such that a pipe is provided which branches from an oil cooler in parallel with an intake pipe of the thrust bearing pushing up device to supply cooling oil.  
     CONSTITUTION: 1 designates a vertical type rotary shaft, 2 a rotary disc, 3 a stationay plate which slides on the rotary disc 2, 4 an oil tank, 5 a cooler, 6 an air bubble separator, and 7 a pump. 8 designates a pipe which branches from the cooler 5 to the air bubble separator tank 6, extending in parallel with a pipe 5b. If shortage of lubricating oil intake arises due to air bubbles moving up in an intake pipe 6a, oil cooled at the cooler 5 is forcibldy supplied to the air bubble separator tank 6 through the pipe 8. Thus, no shortage of lubricating supply appears to the thrust bearing pushing up device. Besides, since cooled pressure oil is supplied from the pipe 7b to th stationary plate 3, cooling effect is decreased thereby so that any oil supply shortage in the intake pipe 6a can be completely compensated thereby.

Abstract: PURPOSE:To enable a user to utilize a brush as a hair stopper as well by turning over the planar body of the brush to be used by turning over the planar body upward and holding the hair between the brush hairs and a folding part. CONSTITUTION:To use this brush as a brush, the user expands the brush hairs 4 by turning over a brush hair mounting part 7 to an upper side. On the other, hand, to use the brush as a hair stopper, the user reduces the brush hairs 4 by turning over this hair mounting part 7 to a lower side and folds the folding part 3 in this state in such a manner that the hair is held between the brush hairs 4 of the hair mounting part 7 and the hair retaining part 16 of the folding part 3. The elastic piece 18 of the folding part 3 is thereafter engaged with the projecting part of the brush body 2. The spacing between the brush hairs 4 of the brush body 2 and the hair retaining part 16 of the folding part 3 is widened in a folding posture in the case of mounting by setting the curving direction of the hair retaining part 16 of the folding part 3 and the curving direction of both bar-shaped holding parts of the brush body 2 at the same direction. Stopping of the hair of oven having the much hair, etc., without damaging the hair is, therefore, possible.

Filed: 1978-12-27
Abstract: PURPOSE: To prevent peeling and crack of an enclosing material by providing a semiflexible resin intermediate material by dipping and a lid type resin enclosing material by powder coating in sequence on the outer periphery of a hybrid IC.  
     CONSTITUTION: A passive element 2 is placed on a ceramic substrate 1 to constitute a hybrid IC, and a semiflexible epoxy risin is applied thinly on its outer periphery through dipping to form an intermediate material 5. Then, a lid type resin like epoxy or phenol resin is applied to the outer periphery of the intermediate material 5 through powder coating to form an enclosing material 6. The semiflexible resin is superior in adhesive property for hybrid IC and lid type resin as well, therefore the enclosing material can be prevented from peeling by the constitution described above. Further, the enclosing material can be prevented from crack also by relieving a difference in the coefficient of linear expansion between enclosing material and IC and a strain of shrinkage of the enclosing material during curing with the intermediate material.
