IPC: E03D11/02
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To improve a connecting strength by an increase in a connecting area of a bowl part to a rim and to upgrade an appearance display by a prevention of a disconnection of a connecting part by increasing base thicknesses of the connecting part of an upper peripheral edge of the bowl part and the connecting part of a lower surface of the rim opposed to the connecting part of the bowl larger than that except the connecting part. SOLUTION: Thicknesses of an upper edge 1a of a connecting site of a bowl part 1 and a lower surface 2a of a connecting part of a rim 2 opposed to the edge 1a are set to a larger minimum thickness of those except a part to be connected. After the bowl part 1 and the rim 2 to be separately cast molded are taken out of a casting mold, the rim 2 is connected to an upper part of the bowl part 1 by using an adhering slurry so that boundaries of different thicknesses may smoothly change in thickness. Thus, a connecting area is increased to improve a connecting strength of the bowl part 1 to the rim 2. A disconnection of the vicinity of the connecting part immediately after connecting or after drying is prevented so that the connecting part is not evident to obtain a product having a good appearance display.

Title: Dust cover
Inventor: EDO TOMOYOSHI
IPC: F16F9/38
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent dust, water and sand from entering a slidingly movable surface of a piston rod and a seal surface of the piston rod and a housing by fitting it to a lower end part inner periphery of a dust cover so as to slidingly movable on an inner cylinder surface of the housing, and forming a projecting part of a flange part. SOLUTION: Since an inside diameter of a projecting part 17 formed on an inner peripheral surface of a dust cover 1 under a flange part 14 is smaller than an outside diameter of the flange part 14, even if a piston rod 2 largely extends by receiving vibration from the outside, the projecting part 17 is locked on the flange part 14, and slipping out is prevented. Therefore, a slidingly movable surface of the piston rod 2 and a seal surface of the piston rod 2 and a housing 3, can prevent an entrace of dust, water or sand into the dust cover 1. Since the projecting part 17 arranged in the dust cover 1 can slidingly move to the housing 3, the dust cover 1 does not extend/contract, and durability of the dust cover 1 can be improved.

Title: High-speed weaving method and heald therefor
Inventor: YAMASHITA ISAO
IPC: D03J1/14
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the quality of a woven fabric caused by so-called 'uncontrolled heald motion' in the weaving especially at a speed of >=900rpm. SOLUTION: Weaving is carried out by using a heald 1 having its gravity center deviated in the longitudinal direction from a warp-insertion mail 3 and placing the gravity center of the heald 1 below the warp-insertion mail 3. Since the gravity center is positioned below the warp-insertion mail 3, the rotation of the heald 1 is suppressed by the moment applied to the heald by the gravitational force when the heald 1 is lifted by the warp.
