Title: Method of enlarging pile hole diameter
Inventor: OKANOE MORIO
IPC: E02D7/00
Filed: 1984-08-30
Abstract: PURPOSE:To enable increasing of the titled diameter easily even by means of a small driving device, by a method wherein, after a hole is excavated by means of an earth drill, the bucket of the earth drill is removed, a diameter enlarging excavator is attached, the lower it, and the bottom of a pile hole is excavated for an increase in diameter. CONSTITUTION:A stand pipe 9 is installed in an open hole, and excavation is effected by a drilling bucket 4 attached to the tip end of a Kelly-bar 3. The drilling bucket 4 is pulled up to a ground surface to remove it from the Kelly- bar 3, a size enlarging excavator, set to the forward end of the Kelly-bar 3, is lowered to a hole bottom. A driving force is produced by a rotary driving device 5a, and a bit 5b is unfolded to perform excavation for enlargement of the diameter. This enables the Kelly-bar 3 to produce a reaction force when enlarging excavation takes place, resulting in the possibility to enlarge diameter without applying an excess load on a member and even by a small driving device without difficulty.

Abstract: PURPOSE:To obtain a filter device having improved durability by providing a treating tank for introducing a liquid to be treated and a freely rotatable filter drum in the treating tank, and allowing said liquid to be treated to collide with the surface of said filter drum. CONSTITUTION:Cutting oil A is charged into a treating tank 2 through an inlet 6 of a liquid to be treated provided on a cover plate 5. The cutting oil A flows down while being spread on an sloped part 3 in a width direction of the sloped part 3, and collides against a filter drum 10 with an energy enlivened by the falling. A liquid fraction of the cutting oil A permeates a filter cylinder of the drum 10 into its inside, and flows out naturally from a liquid outlet 17 to a specified section for treating the liquid fraction. On one hand, almost all of chips (a) in the cutting oil A precipitates in the cutting oil A in a housing section 4 of the drum in the tank 2, where it is scraped by a scraper 48 moved by the rotation of a driving chain 41 and transported upward, then discharged through a discharging port 9 to a specified treating section for the chip. On the other hand, chips(a) having stuck to the surface of the filter cylinder 13 are washed off by the cutting oil A by the effect of rotation of the drum 10.

Title: Shared resource control method
Inventor: SATO MASATOSHI
IPC: G06F12/08
Filed: 1991-06-10
Abstract: PURPOSE:To effectively utilize resources by making the best use of the advantages of a division local control and an end batch centralized control for copied empty resources. CONSTITUTION:Each processor is provided with a cache memory, respectively and separately to access resources on a share memory. When empty resources occurs in the resources copied on the cache memory, this is controlled by a cache memory control part without immediately returning it to the side of a share memory. Therefore, each processor requests the cache memory control part to assign the empty resources. Only when the empty resources on the cache memory does not exist, each processor requests a share memory control part to assign the empty resources. When resources is got out of the cache memory, the control of the resources is transferred to the share memory control part if it is empty resources.

Abstract: PURPOSE:To simplify the manufacture of a two layer resin pipe made of different kinds of resin by such an arrangement wherein a vacuum suction passage is provided between a passage for extruding resin for core material and another passage for extruding resin for surface layer which is concentrically provided with the core material extruding passage. CONSTITUTION:A kind of resin for core material such as vinyl chloride reaches a contact hole 24 of a contact plate 20 through an extrusion passage 6 for core material resin and an outlet 17 and another kind of resin for surface layer such as AAS, etc. also reaches the contact hole 24 of the contact plate 20 through an extrusion passage 11 for surface layer resin and an outlet 14. As a cylindrical resin for surface layer is caused to closely contact with a cylindrical resin for core material, a two layer resin pipe is formed and it is sized by an outsizing die 27 and a product is thus obtained. In causing the resin for surface layer to closely contact with the resin for core material, it is possible to cause them to closely contact each other by making the gap between them vacuous through a vacuum suction passage so that air doesn't enter between them. The thickness of the layer of surface resin can be adjusted by varying the gap of the outlet 14 by means of an adjusting screw 13.

Title: Container used as aerosol can
Inventor: YOSHIGA NORIO
IPC: B65D83/38
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To improve a corrosion resistance and make various kinds of aerosol propellants usable by a method wherein a specific metal laminate covered with a composite film made by laminating a plurality of specific resin layers on one another is drawn to form a container so that the resin layers are positioned inside the container. SOLUTION: At least one of faces of an aluminum sheet or a steel sheet is necessary to be covered with a composite film with the aid of an acid- modified polyolefin resin, and an adherent resin modified with an acid component by a graft reaction is used. The composite film for covering one face of the metal sheet with the aid of the acid-modified polyolefin resin is used by laminating a polyethylene resin layer or a polypropylene resin layer on both sides of a vinyliden chloride resin layer. A metal laminate thus obtained by laminating the composite film on the metal sheet under heating is drawn to form a container so that the resin layers are positioned on an inner face side of the container.  By this method, a problem of corrosion by the contents of a liquid even in the case of a strong-acidic hair dye can be solved, and the contents can be sprayed in a foggy state or in a foamy state by using dimethyl ether or liquefied natural gas as an aerosol propellant.
