Title: Drain material for civeil engineering
Inventor: MORIWAKI ATSUSHI
IPC: E02D3/10
Filed: 1993-02-17
Abstract: PURPOSE:To prevent the occurrence of lie-down and provide high permeation performance by using a drain material for civil engineering having a specified relation between a distance between permeable sheets, density of binding yarn, and the size of a binding yarn. CONSTITUTION:Fiber sheets 1 and 2 are intercoupled by a binding yarn 3 by means of a Raschel loom. In this case, a distance between the fiber sheets 1 and 2 is set to 3-50mm so that tie-down is prevented from occurring and permeability is prevented form lowering. Further, density P of binding yarns is set to 50-200 pieces/in<2>. By taking an earth pressure and flexural rigidity into consideration, a diameter D of the binding yarn is set to 100-5000 denier. A value of a relation formula DXP/L<2> between the distance L, the density P of binding yarn, and the diameter D is set to 80-12000. This constitution causes provision of a drain for civil engineering having excellent pressure resistance, permeability, and workability.

Filed: 1989-02-07
Abstract: PURPOSE:To subject a stainless steel sheet to mirror face polishing uniformly without unevenness by moving a polishing device orthogonally with the direction transferring a stainless steel sheet and constituting a rotating buff so as to polishing it by abutting to the surface of the stainless steel sheet. CONSTITUTION:A stainless steel sheet S is fed onto a polishing base 8 by a transfer means 7 and a polishing means 10 is moved to the polishing start position of the stainless steel sheet S by a driving means 9. The polishing is then started by pressing to the surface of the stainless steel sheet S while rotating a buff 29 by driving a rotating means 31. At this time, the polishing means 10 is moved in the direction orthogonal with the transfer direction (a) of the stainless steel sheet S by a driving means (consisting of a traveling mechanism 21 and its motor 27). Whenever this stainless steel sheet S is polished in the width direction at a constant width, the transfer means 7 is intermittently driven to advance the sheet S in a certain distance each. By repeating the polishing work like this, the whole surface of the stainless steel sheet S can be subjected to mirror face polishing uniformly without unevenness.

IPC: G06T7/20
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a supervisory system with high detection accuracy where a malfunction hardly takes place even when a supervision environment is changed. SOLUTION: A changing supervisory point supervising a motion of an object and a no-change supervisory point, whose supervisory point is unchanged even when the object is moving, are set to a supervisory image in advance. Only a luminance signal is obtained from a video signal sent from a video camera 1 through a Y/C separate circuit 3 and given to an A/D converter circuit 5, where the signal is converted into digital data and the data by one image are stored in a memory 8. Then the data stored in the memory 8 are read and stored in a newest-data memory 11. When data for a succeeding image are received by the memory 8, data stored in the newest-data memory 11 are moved to a precedence-data memory 12 and the data for succeeding image are received from the memory 8 to the newest-data memory 11. Data in the precedence-data memory 12 and the data in the newest-data memory 11 of one image after the image corresponding to the data in the memory 12 are compared sequentially, and in the case that there is any change in the data corresponding to the changing supervisory point and there is no change in the data corresponding to the no change supervisory point, it is discriminated that the object is moving and a sensing output is sent.

Title: Storage battery
Inventor: MORI KAZUMI
IPC: H01M50/122
Filed: 1984-02-18
Abstract: PURPOSE:To make a container and a cover thin and light weight without decrease in rigidity by forming them with a low foam synthetic resin. CONSTITUTION:Stearic acid, salicylic acid, or amino acid is added to polyolefin family synthetic resin as a foaming agent and the resin is made to foam so as to have 5-25% porosity. A container and a cover are molded by injection of the foam resin. A plate group is accommodated into the container, and the container and the cover are melt-bonded. When the resin having a porosity of 25% or more is used, the deformation is minimum and almost constant. When the resin has a porosity of 5% or less, the effect of foaming is small. When 5-20% of quartzite is added to the low foam polyolefin family synthetic resin as reinforcing filler, rigidity of the container and cover is increased.
