摘要:
An electrolyzer is provided with a vessel containing an electrolyte and in which a lower temperature portion and a higher temperature portion are respectively defined, and with stirring devices or the like for forming circular flows of the electrolyte within the lower and higher temperature portions respectively and for circulating the electrolyte between the lower and higher temperature portions to permit the electrolysis to be carried out.
摘要:
A high valency salt, such as TiCl.sub.4 is reduced to a lower valency salt, such as TiCl.sub.2 and/or TiCl.sub.3 within a fused salt electrolytic bath via electrolysis so that an improved electrodeposition of a desired metal or alloy, such as Ti, occurs, from such adjusted bath. The process generally comprises adding a higher valency salt of a desired metal or alloy to a fused salt electrolytic bath, reducing the higher valency salt on a cathode electrode to a lower valency salt, removing the so-produced lower valency salt from the electrode surface and maintaining a predetermined amount of the lower valency salt within the electrolytic bath. Electrodeposition of a desired metal or alloy may then take place from such electrolytic bath containing a so-adjusted amount of the lower valency salt.
摘要:
In the electrodeposition of titanium metal from an electrolyte containing one or more dissolved or fused titanium chlorides and other dissolved or fused chloride salts, such as, MgCl.sub.2,CaCl.sub.2,NaCl, and the like; the hardness of the electrodeposited titanium is adjusted by adding to the electrolyte one or more oxides, such as titanium oxide and oxides of alkaline and alkaline-earth metals, and/or one or more fluorides of alkaline and alkaline-earth metals.
摘要:
In an electrodeposition process using a fused-salt electrolyte in which a desired metal or alloy deposited by electrolysis can be dissolved, and/or using a fused-salt electrolyte from which a highly viscous material is produced on the surface of an electrodeposited metal or alloy upon electrodeposition of the desired metal or alloy, solid particles are dispersed in the aforesaid electrolyte in order to obtain a flat surface of the desired electrodeposited metal or alloy, whereby continuous electrodeposition can be carried out.
摘要:
An electroposition process wherein solid metallic particles are produced in a fused salt electrolytic bath and dispersed therein to electrodeposit a metal or alloy thereof on a cathode so that the surface of the deposit is maintained smooth and flat. In order to produce particles of a desired metal or alloy, an auxiliary electrolytic means may be provided within an electrolytic cell so that such particles are generated in situ within the fused bath of such cell.
摘要:
An electrodeposition method of electrodepositing a material with a flat and smooth surface, in which an electrolytic condition such as a speed of movement of a cathode relative to an electrolyte, an electrolytic current density, a duty ratio of an interrupted electrolytic current or an interruption frequency of an electrolytic current is changed periodically from a normal value to another value and back again.

An electric power steering device includes: a worm shaft including a first end portion and a second end portion; a worm wheel; a joint; and an urging member. The first end portion includes: a first tubular portion; a diameter enlargement permission portion to allow enlargement of a diameter of the first tubular portion; and an external teeth portion. The joint includes: a second tubular portion; and an internal teeth portion capable of engaging the external teeth portion. The electric power steering device further includes a diameter enlargement member which is arranged in the first tubular portion and which enlarges a part of the first tubular portion in an axial direction thereof to press the internal teeth portion toward the external teeth portion.
摘要:
A pneumatic actuator for use in a vibration damping device comprising: a base housing; an elastic wall member being fastened fluid-tightly to the base housing to form a working air chamber therebetween; and an urging member positioned within the working air chamber for exerting urging force on an output portion provided to the elastic wall member, such that the output portion is actuated to undergo displacement in opposition to the urging member through change in an air pressure in the working air chamber from an outside. At least one of opposing faces of the base housing and the elastic wall member on the working air chamber side thereof has a plurality of rib portions which extend from an inner circumferential side thereof towards an outer circumferential side thereof. A vibration damping device equipped with the pneumatic actuator is also disclosed.

A vehicle steering apparatus comprises a rack shaft, a joint provided at an end of the rack shaft, a stopper for regulating a stroke amount of the rack shaft, and a spacer. The spacer comprises an annular elastic member and an annular metal member. The elastic member comprises an inner annular section fitted on the end of the rack shaft and an outer annular section. The metal member comprises an annular section surrounding an outer periphery of the outer annular section of the elastic member. The outer annular section of the elastic member comprises a projection section projecting farther to the stopper than a first abutment section of the metal member when the stopper does not regulate the stroke amount of the rack shaft.
