Title: Attaching/detaching method of spline nut to spline shaft
Inventor: USAMI YOSHIYUKI
IPC: F16D1/06
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent a steel ball from falling off when a ball spline is to be mounted to an Z-axis unit by connecting a shaft for attaching/detaching with the same diameter as that of the spline shaft to the spline shaft, and sliding a spline nut to the shaft for attaching/detaching and removing it from the spline shaft. SOLUTION: For mounting a ball spline 3 where a spline nut 31 is engaged to the upper and lower parts of a spline shaft 32 to a Z-axis unit 2, a shaft 5 for attaching/detaching is first mounted to the lower edge of the spline shaft 32. In this case, since the shaft 5 for attaching/detaching has the same diameter as that of the spline shaft 32, each shaft outer-periphery surface is connected without any gap. Therefore, when the lower spline nut 31 is slid along the shaft 5 for attaching/detaching and is removed from the spline shaft 32, a steel ball 33 does not fall off a groove 31d. Also, when the shaft 5 for attaching/detaching is removed from the spline shaft 32, the steel ball 33 is pressed to the outer periphery of the shaft 5 for attaching/ detaching to prevent falling off.  Then, after the spline shaft 32 is inserted into a through hole 2a of the Z-axis unit 2, the shaft 5 for attaching/detaching with the spline nut 31 is mounted to the spline shaft 32. In this case, the steel ball 33 does not fall off as in the removal.

IPC: H04B1/10
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate the need of manual switching, and also, to reduce the deterioration of a receiving condition caused by the mixture of an ignition noise by lowering automatically sensitivity of a tuner in accordance with the start of an engine. CONSTITUTION:In a tuner 2, a gain switching circuit 7 is provided, and this gain switching circuit 7 is connected to a main switch 8, and constituted so as to be operated in accordance with a turn-on position of an ignition switch. That is, it is constituted so that the gain is lowered at the time when the ignition switch is in an engine start position (IG2 of the main switch 8). On the other hand, it is constituted so that the gain is reset to a normal state at the time when the engine is stopped. In such a way, it is unnecessary that a driver executes a sensitivity switching work, and in accordance with the cause of noise at the time of driving the engine, a receiving normal state of a necessary broadcasting radio wave can be secured under a desired condition.

Title: Optical beam control circuit
Inventor: ONUKI NOBUTAKA
IPC: G11B7/09
Filed: 1987-12-23
Abstract: PURPOSE:To reduce noise by decreasing the loop gain of a loop circuit when a high frequency band component, which is removed from the output of a phase compensating circuit by a high-pass filter, goes over a constant amplitude. CONSTITUTION:An optical detector 1 is united with an optical beam driving device 5 and the moving of an optical beam is detected. Then, an error signal is outputted. This error signal is inputted to a phase compensating circuit 2. This output removes the gain rise of a low frequency band due to phase delay compensation by a high-pass filter 6. This output is inputted to a level detecting circuit 7 and here, when the output is over the constant amplitude value, a signal is outputted during this period and a signal passing gain from a phase compensating circuit 2 of a gain switching circuit 3 to an amplifier 4 is decreased. Thus, even when a high frequency noise due to a fine flaw, etc., which is stuck on the surface of an information recording disc 8, is amplified by the phase compensating circuit 2, the gain is decreased by the gain switching circuit. Thus, the large amplitude is not impressed to the optical beam driving device and the generation of noise is reduced.

Abstract: PURPOSE:To entirely eliminate light losses by disposing a prism coupler constituted of an optical prism, a specific gap layer and a waveguide layer into the optical path of a light source and a condenser lens forming a spot on a recording medium. CONSTITUTION:The divergent light from a semiconductor laser 1 is collimated by a collimating lens 2 and is made incident on the prism 3 constituting the prism coupler 6.

Abstract: PURPOSE:To highly efficiently diagnose the insulation of a power cable line with a less amount of associated work by applying the output DC voltage of an AC-DC converting converter across the line and measuring the current flowing to an instrument current transformer installed to an earthing conductor. CONSTITUTION:The supply of an alternating current to a cable line 5 is stopped by opening both change-over switches 2 and 4 and a switch 9 is closed by opening load-break switches 10a, 10b, and 10c. A DC voltage outputted from the converter section 1b of an inverter 1 is applied across the conductor 6 of the cable line 5 and the ground through the switch 9. When a dielectric breakdown occurs in the line 5 and a leakage current is generated between the conductor 6 and the shielding layer 7 of the line 5, the leakage current flows through an earthing conductor 11 and a kicking or varying current generates a signal in an instrument current transformer 12. A measuring instrument 13 detects the signal.
