Title: Ball seat for ball joint
Inventor: NEMOTO AKIRA
IPC: F16C11/06
Filed: 1992-02-19
Abstract: PURPOSE:To reduce operation torque and improve load resistance by forming a circumferential type of inner wall groove on the inner wall surface of a ball seat between the spherical head of a ball stud and a housing along an equator line. CONSTITUTION:A ball seat 5 uses synthetic resin or synthetic rubber having elasticity and abrasion resistance, such as polyethylene and polyurethane, and the radius of the inner wall surface 13 of the ball seat 5 is made equal to or slightly less than the radius of the spherical head 4 of a ball stud 2. The inner wall surface 13 is thereby caused to apply a pre-load to the spherical head 4 at the time of coupling. A circumferential inner wall groove 14 is formed on the inner wall surface 13 of the ball seat 5 in such a way as meandering along an equator line X thereon, with a part of the groove 14 overlapped on the line X. According to this construction, the axial vertical load of the ball joint 1 is received by an inner wall surface 13a convex in the direction of the line X. Load resistance can, therefore, be improved and load balance becomes good, thereby enhancing the durability of the ball seat 5. Also, operation torque can be lessened by reducing a contact area between the spherical head 4 and the inner wall surface 3.

Inventor: SAKATA MICHIO
IPC: F01K21/00
Filed: 1981-05-12
Abstract: PURPOSE: To start and stop desalting towers with good performance by selecting the desalting towers of the longest operation time under stopping and those of the shortest operation time under starting and emitting start and stop commands when the starting and stopping conditions of the desalting towers hold.  
     CONSTITUTION: The input signals P1, P2...Pi of the power generation process required for the decision of the starting (stopping) timings of desalting towers 2-1, 2-2,...2-n read in by an input processor 1. The under-operation signals OPR1, OPR2,...OPRn from the desalting towers and the under-regeneration signals K1, K2...Kn are also inputted to the processor 1. An operating time integrating device 3 reads the under-operation signals and the under-regeneration signals periodically through the processor 1 and integrates the operation time when the towers are under operation and clears the operation time when under regeneration. A starting-stopping selector 4 selects the desalting towers of the longest operation time out of those under stopping and emits start commands S1, S2...Sn.

Filed: 1979-06-05
Abstract: PURPOSE:To avoid the necessity of synchronism of switching, by transmitting digital data and call signal by means of multiplex system for analog signals. CONSTITUTION:A digital data signal is converted into an analog signal at an FS modulation section 11 and input to a multiplex section 12. A call signal is input to the multiplex section 12 directly for multiplex. The multiplex signal is in pulse modulation at a PWM or PPM modulator 13 and converted into a digital signal. This signal is converted into a photo signal at an electro-optic conversion section 14 and transmitted to an optical transmission line 15. At the reception section, the analog signal in photoelectric conversion, PWM or PPM demodulation is separated into a data signal and a call signal at a separation section 18 and the data signal is FS-modulated to be the digital data. Thus, the synchronism for switching is not required.

IPC: H01G11/20
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To reduce costs and increase breakdown voltage and capacitance by heat-treating a carbon raw material in an inert gas atmosphere for carbonization, then dipping a melted alkali metal, and then dipping it in a solvent that reacts with the alkali metal. SOLUTION: As a carbon raw material that becomes a starting raw material, oil/coal coke, pitch, and a phenol resin are used. Heat treatment is made at 700-1,000 deg.C in a nitrogen gas atmosphere as an inert gas for carbonization treatment. A melted alkali metal is dipped into the obtained carbonized material to form the mixture of an alkali metal containing carbon and metal potassium. A carbon material 90 for electrode is composed mainly by a structure body 96 where microcrystalline carbon 94 (the net plane of the microcrystalline carbon 94 is vertical) similar to graphite is laminated in a layer while being piled up with an irregular angle. As a result, for manufacturing the carbon material for electrode and an electrical double-layer capacitor, various kinds of materials are used, thus reducing the manufacturing cost and improving safety in a manufacturing process while achieving large capacitance and high breakdown voltage.

Abstract: PURPOSE:To reduce the expansive tendency at the tube bottom part by detecting a diameter expansion amount at the tube bottom part generated by a mandrel remained in the bottom part after tube manufacture finishing and using a mandrel provided with a expanded head by a size corresponding to a diameter expansion amount. CONSTITUTION:A diameter expansion amount of the bottom part generated by temporarily remained mandrel in the bottom part of a tube P is detected by comparing the amount with a diameter of the top and intermediate parts of the tube P. A mandrel 4, provided with a head 4b having a diameter corresponding to the expansion amount or a larger diameter than the corresponded diameter at the top end of the mandrel 4, is used to hot extrude the tube P. Therefore, a part facing the head 4b is cooled with the inside diameter of the facing part restrained from contraction and other parts contract to a position being in contact with the peripheral surface of a body part 4a without restraint. An extent of expansion is reduced by contraction after temporary expansion when the mandrel 4 is later pulled out because an endothermic amount is small.
