Title: Ball joint
Inventor: KOGA HIRONORI
IPC: F16C11/06
Filed: 1995-06-30
Abstract: PURPOSE: To reduce operating torque required to oscillate a ball stud by bringing the end part of a curved opening part of a bearing into contact with a spherical head part of the ball stud and a housing in an assembled state after caulking so as to form clearances on both axial sides of a protruding part in the bearing. CONSTITUTION: At the time of press-fitting a bearing 5 into a housing 11, a protruding part 6 of the bearing 5 is pressed to the inner peripheral surface of the housing 11, so that the center of the bearing 5 and the center of the housing 11 can be positioned to coincide with each other. The outer diameter of a curved opening part 9 of the bearing 5 is smaller than the inner diameter of the housing 11, and the protruding part 6 is of tapered shape, so that clearances S are formed on both axial sides of the protruding part 6 in the bearing 5 in the assembled state after caulking. Contact area between the outer peripheral surface of the bearing 5 and the inner peripheral surface of the housing 11 is therefore reduced, and as a result, operating torque at the time of a ball stud 2 being oscillated can be reduced.

IPC: C23C18/38
Filed: 1990-07-17
Abstract: PURPOSE:To enable direct copper sulfate plating on an electroless plating film on plastics without damaging the electroless plating film by providing a small conductive area for a basket used for barrel plating method and intermittently sitrring the plating liquid. CONSTITUTION:Plastic products treated with electroless plating are put in a box-type or cylindrical basket. The conductive area of the basket is specified to half or less than the conductive area of the products. First, the plating liquid is not stirred for about 5-10 minutes. After 5-10 minutes from the beginning of plating, contact points between the products and the basket are intermittently moved and the liquid is also intermittently stirred. In this procedure, moving the contact points and stirring are performed according to the plating state of the products. Thereby, direct plating on an electroless plating film on plastics is possible by barrel plating method with using a copper sulfate plating liquid having high acidity. The copper sulfate plating film is excellent in thichness and gloss, and qualities of copper electroplating films are improved.

Title: Manufacture of silicon diffraction grating
Inventor: OOTA TSUNEAKI
IPC: G02B1/02
Filed: 1981-11-27
Abstract: PURPOSE:To manufacture a silicon diffraction grating with a large angle of dispersion by cutting rectangular grooves in a silicon single crystal substrate and by carrying out etching depending on both orientations from the grooves. CONSTITUTION:A lattice etching mask 2 is formed on a silicon single crystal wafer 1, and rectangular grooves 7 each having depth (h) and width (l) are cut under the spaces of the mask 2. It is preferable that the sides S of the grooves 7 are flat and vertical along the sides of the mask 2. Etching utilizing the dependency of the etching speed on the crystal face orientations is then carried out from the grooves 7. Since the side etching speed at parts under the mask 2 can be increased, the time required for etching can be reduced, and an etching mask having a fine pattern can be used. Thus, the extent of etching is correctly controlled, and a silicon diffraction grating with a large angle of dispersion is manufactured.

CONSTITUTION:An inflow valve 12 is separated from an inflow valve seat 8 against a spring force of a spring 14 by an action force by a pressure difference of a pressure of a load passage 5 side, which works opposingly to a piston 18 and a pressure of a pilot air whose rise is adjusted. When the pressure difference which works opposingly to the piston 18 is eliminated, the inflow valve 12 is attached to the inflow valve seat 8 by the spring force of the spring 14. Accordingly, as for the spring force of the spring 14, a small force which can attach and hold the inflow valve 12 to the inflow valve seat 8 will suffice, and even if the pressure of the load passage 5 side approaches the pressure of the pilot air whose rise has been adjusted and the action force goes to small, in a state that the inflow valve 12 is separated from the inflow valve seat 8, the inflow valve 12 can be separated to a large side from the inflow valve seat 8. In such a way, the pressure of the load passage 5 side can be set quickly to a desired value which has adjusted a rise.
