Title: Ball joint and its preparation
Inventor: SUMIYOSHI KIKUO
IPC: F16C11/08
Filed: 1978-12-26
Abstract: PURPOSE: To prevent abrasion and falling-off of ball head by making the radius of curvature of concaved spherical part of inner surface of casing close to that of ball head housed in the casing, while making the hardness of inner surface of casing equal to or lower than that of ball head.  
     CONSTITUTION: Ball head 20 is housed in casing 30 and supported by surrounding upper seat 40 and lower seat 50. Upper seat 40 is a thin layer of synthetic resins composed of adhesive layer 40 a  and shearing-move layer 40 b , which shows caracteristics of self-lubrication and anti-abrasion and is capable to prevent low-temperature flow under load. The difference of R 1  of concaved spherical surface of the inside of casing 30 from radius of curvature of ball head 20-R is made to be small, while the hardness of inner surface of casing is made to be equal to or lower than that of the ball head. If any abrasion should occur on the upper seat, the ball head is to touch on the surface of casing, thus progress of abrasion and falling-off of ball head from casing being prevented and the durability being improved.

Inventor: TSURUTA MAKOTO
IPC: B21B37/00
Filed: 1990-06-21
Abstract: PURPOSE:To obtain the plate of a correct plate crown and a satisfactory shape by correcting a case which cannot attain the target crown and shape by using shape correction operating force by rolling force and plate thickness given by a schedule calculation, by rescheduling the plate thickness rolling force. CONSTITUTION:A schedule calculating device 11 executes a schedule calculation of plate thickness, rolling force, rolling speed, etc., and based on a result of this calculation, each influence coefficient to a crown and a plate shape is calculated by an influence coefficient arithmetic unit 10. By using this coefficient, roll bending force for obtaining the target crown and shape is derived by a roll bending force preset arithmetic unit 9, and when the control becomes impossible, with respect to this preset value derived once, a correcting calculation of plate thickness and rolling force is executed by a schedule re-arithmetic unit 8. Roll bending force and plate thickness derived in such a way are outputted to a roll bending force setting device 4 and a plate thickness setting device 5 and controlled.

IPC: B29L31/58
Filed: 1989-06-29
Abstract: PURPOSE:To enhance quality by preventing the fluff of a cover material from becoming reverse by arranging a flexible cover composed of a nylon knitted fabric on the raising of the cover material in a tensioned state and interposing a cover between a press mold and the raising to bring both of them to a non- contact state and pressing the cover material in this state by the press mold. CONSTITUTION:The cover 8 suspended from an upper mold (press mold)2 by steel wires 7 having elasticity is arranged above the cover material 4 set to a lower mold 1 in a tensioned state. The cover 8 is constituted of tricot formed by knitting a nylon filament having fineness of 30 denier. When the upper mold 2 falls, the cover 8 presses the fluff of the cover material 4 of an upper flat part 3a and comes into contact with the boundary of an inclined part 2b and a downward protruding part 2c at the same time and, when the cover 8 further falls, the fluff of the cover material 4 placed on the inclined part 3b of a hard board 3 is brought into contact with the cover 8 from the part positioned in the vicinity of the upper flat part 3a to press the fluff by the cover 8. Since the cover 8 is extremely slidable, the fluff slides on the surface of the cover 8 and more strongly lies down in the same direction as a direction wherein the raising is preliminarily inclined.
