Title: Rack-and-pinion type steering device
Inventor: OTSUKA JOJI
IPC: F16H55/28
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a rack-and-pinion type steering device which allows a smooth movement of a rack shaft despite having a capability of preventing an occurrence of backlash, and which is inexpensive and has a high durability. SOLUTION: In this rack-and-pinion type steering device 1, an occurrence of backlash can be prevented because a rack shaft 3 is energized by a spring 6 to a pinion shaft 2 side. The rack shaft 3 can move smoothly because a ball member 4 rolls along a first groove 3b recessed in the rack shaft 3 and turns inside of a second groove 5a recessed in a rack support 5. Further, this rack pinion type steering device 1 can be inexpensively manufactured because it is simple in structure and does not require a high working accuracy.

Filed: 1988-01-25
Abstract: PURPOSE:To enable high-speed recording and erasing by forming a thin film consisting of a In-Sb-Se at <=1nm/sec film forming speed. CONSTITUTION:The thin alloy film 2 consisting of the In-Se-Sb is formed as a recording film on a substrate 1 by a vacuum deposition method and the film forming speed is confined to <=1nm/sec. The cooling rate of the thin film forming atoms. in the process of the film formation is, therefore, increased and since the film is formed in a low temp. state and by rapid cooling, the reaction with a residual gaseous component and the retransfer of the atoms. are hindered and the film is hardly oxidized and segregated. The high-speed recording and erasing are thereby enabled with the thin indium-antimony- selenium film of a wide range of compsns.

Filed: 1981-02-04
Abstract: PURPOSE:To obtain optimum pulse waveforms through regulation of average welding current, to transfer globules smoothly and to stabilize the arc by making peak current, peak current time and base current constant and changing base current time.
