Title: Treatment of head of cast-in-place pile
Inventor: TAKAHASHI YOSHIHIKO
IPC: E02D5/34
Filed: 1983-09-17
Abstract: PURPOSE:To make easier the treatment of the head of a cast-in-place pile by a metod in which concrete is placed into a pile pit, a bucket is buried in the extra- banking portion of the pile head, and after the concrete hardens, the bucket with concrete piece is drawn out. CONSTITUTION:A stand pipe 2 is penetrated into the upper inner wall of a pile pit 1, and concrete is placed into the pile pit 1. Afterwards, concrete pieces are put into the extra-banking portion 5a of the pile head, a steel bucket 6 is buried in the extra-banking portion, and the stand pipe 2 is pulled out. After the concrete 5 hardens, the bucket 6 with concrete pieces is pulled out, and the extra-banking portion is broken. The remaining extra-banking portion is then treated. The head of piles can thus be simply treated in a short time.

Title: Exhaust gas recirculation device
Inventor: SUZUKI FUMITADA
IPC: F02M25/07
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent the contraflow of recirculation gas to a throttle valve through an intake pipe and adhesion thereof as deposite in an exhaust gas recirculation device. SOLUTION: In the case of a butterfly throttle valve 3, an opening 15 is usually formed vertically across a rotary shaft under a slightly opened state. In the state of drawing, however, a recession 52 formed of a part of a spherical surface is formed by a pipe wall of an intake pipe 5 by means of a thick portion 53. The opening 15 is formed only on a lower portion of the throttle valve 3 while the upper portion of the throttle valve 3 is opposed to the recession 52. Fast flow of intake is concentrated there. A recirculation gas inflow port 9 on a terminal end of a recirculation gas introduction passage 8 is opened correspondingly to the portion. The contraflow of the recirculation gas from the recirculation gas inflow port 9 is prevented, while the gas is fed to the downstream side with certainty.

Title: File copy preventing method
Inventor: OKABA YASUSHI
IPC: G06F21/62
Filed: 1988-07-11
Abstract: PURPOSE:To prevent the outsiders from copying files and to enable a person who performed the writing jobs to restore the files by dividing physically a subject file to write these divided files into the random idle areas of a subject writing disk and defining hereafter these idle areas as the inhibited areas for use. CONSTITUTION:All idle sector numbers of a writing disk 1 are checked (by checking a file allocation table FAT2). Then the random numbers including zero through the maximum sector number, e.g., 10000 is generates. If an obtained random number is included in a group of said sector numbers, the random number is written into the corresponding sector number. In case the obtained random number s not included in the sector number group, the next random number is acquired and the same operation is repeated. Then a 'use inhibiting mark' received from an operating system OS is written into an area of the FAT2 corresponding to the written sector number. Thus the outsiders can never detect the relevant sector number and the person who wrote it can restore the corresponding file in a comparatively easy way.

Title: Composition for synthetic resin magnet
Inventor: ISHIWAKA TAKUMI
IPC: C08K5/544
Filed: 1987-07-10
Abstract: PURPOSE:To improve heat-resistant stability by using a specific silane group coupling agent as a surface treating agent at a specific rate to magnetic substance powder. CONSTITUTION:An silane group coupling agent shown in general formula (in formula, all of R1, R2 and R3 represent a lower alkoxy group or one or two of R1, R2 and R3 represent the lower alkoxy group and the remainder a lower alkyl group) is employed as a surface treating agent within the range of 0.1-3.0 pts.wt., preferably, 0.2-1.0pts.wt., to 100pts.wt. magnetic substance powder. When the surface treating agent is brought to a 0.1pts.wt. or less, the lowering of melt viscosity as the original effect of the surface treating agent is not recognized. When the surface treating agent is brought to a 3.0pts.wt. or more, the improvement of the effect is not expected, and the excessive presence of the surface treating agent is not preferable because physical properties such as impact strength are deteriorated. The addition method of the surface treating agent is not limited particularly, but a method in which the surface treating agent is applied previously to magnetic substance powder is desirable.

Title: Manufacture of gasket made of metal
Inventor: AKUTSU TADAYOSHI
IPC: F16J15/08
Filed: 1992-06-08
Abstract: PURPOSE:To provide a manufacturing method for a gasket made of a metal which prevents the occurrence of crevices, cracks, and strains by processing and hardening a bent part by bending processing through which beads are formed in a resilient metallic sheet. CONSTITUTION:When bending processing is applied on a resilient metallic sheet 8 along a cylinder bore 9A to form beads 10, bending processing of the beads 10 is effected at temperature within a temperature range in which processing hardening is hard to occur at the re-crystal temperature or less of the material of the resilient metallic sheet 8. This prevents the occurrence of processing hardening to a bent part. Thus, the generation of a residual stress, i.e., a residual strain, is reduced at the bent part of the bead 10, a spring back amount is reduced to a minimum, and crevices are prevented from occurring to improve durability.

The Laurus nobilis oil, in a state of being left intact, is oily and hard to be applied; therefore, the oil is pref. used in the form of (aqueous) solution. The solvent to be used for this purpose is pref. ethanol or methanol used in food additives or food processing. The concentration of the solution is pref. 1-70wt.%.  In general, when this repellent is to be used, it is diluted with water and applied; in this case, its dilution is pref. so as to be 0.1-5.0wt.% or so in the concentration of the Laurus nobilis oil.
