Title: Spring collet
Inventor: YAZAKI TOSHIHIKO
IPC: B23B31/20
Filed: 1988-05-30
Abstract: PURPOSE:To improve the rotation accuracy of drill, fine boring accuracy and the service life of drill and to automate the system by regulating the contacting state between the tapered section of a spring collet and the tapered section of the sleeve in a spindle shaft.

Title: Power supply switching device
Inventor: MARUYAMA YOSHIO
IPC: H02M7/217
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To correct the waveform distortion of a power supply voltage with a small number of switching elements by repeating semiconductor element switching several times in the single cycle of AC voltage. SOLUTION: IFBT4A and 4B are fitted to a working power source 1 as semiconductor elements, and IFBT4C and 4D are fitted to a spare power source 2. When an output waveform is controlled, one cycle of power supply voltage is divided into (n) pieces very finely at intervals of time τ0. If the IGBT is turned on only during a period of energizing time in one respective section time τ0 and turned off during the other time, a smooth output voltage waveform is smoothed by an inductance 7 and a capacitor 8 at the rear stage of a circuit. By changing the respective energizing time in one respective section time τ0 during its semi-cycle, and even if a waveform is distorted, it can be compensated for into a normal sinusoidal-waveform.  As a result of this, it is possible to correct the waveform distortion of the power supply voltage with a small number of electric power switching elements.

Inventor: KOBAYASHI KAZUO
IPC: B21B27/02
Filed: 1988-06-01
Abstract: PURPOSE:To reduce wear of reinforcing rolls and to increase rolling amounts up to roll changing by using asymmetric rolls in a rolling mill and reversely changing their position at proper times. CONSTITUTION:As for roll changing of work rolls 2, 3 having asymmetric profile such as S-shape, etc., the rolls 2, 3 are reversed in a combined position shown by the broken lines.
