Title: Constant-velocity universal coupling
Inventor: JIEIMUZU DABURUYUU UAANKU
IPC: F16D3/227
Filed: 1992-08-26
Abstract: PURPOSE: To obtain a cross groove variety of constant velocity universal join that can be made easily adaptable to any joint having a fixed center or an axially movable center. CONSTITUTION: The cross groove universal joint 10 includes an inner race 11 having a plurality of inner race grooves 14 formed in an outer surface 13 of the inner race and an outer race 15 having a plurality of outer race grooves 18 formed in an inner surface 16 of the outer race. The inner race grooves are inclined in one direction relative to the rotational axis, while the outer race grooves are inclined in the opposite direction. A ball 20 is disposed in each of the associated inner and outer race grooves. A cage 21 is provided for retaining the balls in the grooves. Mating spherical surfaces 17, 23 are formed on the inner surface of the outer race and the outer surface of the cage.

Title: Method for recovering combustible and volatile organic compounds
Inventor: IZUMI JUN
IPC: B01D53/34
Filed: 1991-09-27
Abstract: PURPOSE:To prevent oxygen from being mixed with a combustible and volatile organic compound beyond the explosion limits to efficiently recover the organic compound by concurrently purging oxygen remained in a tower with nitrogen in an adsorption process and using nitrogen also for purge gas of a vacuum countercurrent purge regeneration process. CONSTITUTION:Adsorbers 5a-5c, a blower 2, a vacuum pump 12, a nitrogen holder 22, valves, etc., are installed. In an adsorption process, an organic compound (e.g. aldehyde) is adsorbed with a combustible and volatile organic compound adsorbent (e.g. Na-X type zeolite) and nitrogen and oxygen are discharged outside the adsorbers. In a concurrent purge process, nitrogen flows in parallel to the fluid to scavenge oxygen remained in the adsorbers. Further, in a vacuum countercurrent purge regeneration process, the adsorbers are evacuated in countercurrent to the fluid and then nitrogen flows in the same direction to recover the organic compound. As a result, oxygen is prevented from being mixed with the organic compound beyond the explosion limits.

Abstract: PROBLEM TO BE SOLVED: To reduce pressure drop of a return oil from an oil chamber on head side by opening and communicating both of a main return oil passage and a branched return oil passage of a direction change-over valve at the time of shrinkage operation of a hydraulic cylinder. SOLUTION: When pilot pressure is applied from a pilot port 30R at the time of shrinkage operation of a hydraulic cylinder 27, a main spool 29a moves at a stroke in the arrow (b) direction.

Title: Adjustment method for tire internal pressure
Inventor: ITO JINICHI
IPC: B60C23/00
Filed: 1989-09-26
Abstract: PURPOSE:To enable the short-time adjustment of tire internal pressure to the predetermined level by predicting the internal pressure at the time of air pressure relaxation and balance between a hose and a tire in the transient initial stage of air discharge from the hose to the tire, and air charge from the tire to the hose, and performing air charging and discharging operations based on the aforesaid prediction. CONSTITUTION:An air inlet valve 11, an air exhaust valve 12 and an air pressure sensor 13 respectively connected to a compressor as an air pressure source are unitized and connected to the base end of a hose 14. The internal pressure fluctuation of the hose 14 is detected with the air pressure sensor 13. The forward end of the hose 14 is so connected to the check valve nozzle 16 of a tire 15 via a coupler 17 as to be freely detachable. Also, the combination of the check valve nozzle 16 and hose 14 is regarded roughly as a primary system in the transient initial state of air discharge to the tire 15 and air charge to the hose 14. Stabilizing tire internal pressure is estimated in the transient initial stage of hose internal pressure fluctuation, using the time constant of the aforesaid primary system as kept unchanged. Air charge or discharge is determined based on an estimated value, without waiting for an air pressure balance between the hose 14 and the tire 15.

IPC: G11B5/66
Filed: 1984-11-26
Abstract: PURPOSE:To provide an isotropic magnetic characteristic and to make possible the reduction of reproduced output modulation by providing vertical directivity to a horizontally magnetizable film layer. CONSTITUTION:Vertical directivity is provided to the horizontally magnetizable film layer by a means for forming the granular structure in a vertical direction by temp. control, etc. in the case of forming said film layer by sputtering. The isotropic magnetic characteristic is thus obtd. within the film plane and the reproduced output modulation in a magnetic disk, etc. is decreased. Initial magnetic permeability mui in the direction X of of difficult magnetization and has an extremely large difference from the initial magnetic permeability mui in the direction Y of easy magnetization in the region where the vertical anisotropic magnetic field Hk is smaller than 20 (Oe). The initial magnetic permeability mui in the direction X and the direction Y is approximately equal when the magnetic field Hk is made >=20 (Oe). The magnetic characteristic in the magnetic recording plane is therefore made isotropic and the modulation of the reproduced output is made extremely small.
