Title: Semiconductor power conversion system
Inventor: KINOSHITA SHIGENORI
IPC: H02M7/48
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce losses due to a semiconductor switch provided to isolate a power converter, when a load is frequently and repeatedly started and stopped during driving of the load by the converter. SOLUTION: A unipolar semiconductor element is used as a semiconductor switch and the building-up voltage of a parasitic diode is set to a value higher than the on-voltage of the unipolar semiconductor element. Thus unipolar characteristics are provided bidirectionally, and the losses produced in the switch can be reduced. The switch is placed on the direct-current side and alternating- current side of the power converter.

Title: Table driving method of grinding machine
Inventor: ISHIDA MICHIYASU
IPC: B24B47/04
Filed: 1987-12-07
Abstract: PURPOSE:To readily prevent a grinding surface from generating chattering in grinding by connecting the nut provided to the ball screw side and the nut holder integrally fixed to the table side through cushion material. CONSTITUTION:The turning effort of a drive motor 3 is transmitted to a work table through a transmission comprising a ball screw 5, nut 9 and nut holder 12 to reciprocate the table 1. In this case the vibration in the side of the ball screw 5 is absorbed in cushion material (rubber, for example)10-1 and 10-2 lying between the nut 9 in the side of the ball screw 5 and the nut holder in the side of the table 1 resulting in becoming hard to be transmitted to the side of the table 1. The vibration generated in the side of the table 1 due to grinding operation is also reduced because of this cushion material. As a result the generation of chattering in grinding can be relatively readily prevented.
