Title: Method for grinding lens
Inventor: LI YUAN-SUNG
IPC: B24B7/24
Filed: 2000-05-09
Granted: 2002-10-11
Abstract: The present invention relates to a method for grinding lens wherein rotational speed of a driving motor is controlled by a speed controller whereby speed can be changed in the cutting and grinding process. In an initial phase of cutting, a low speed is taken in cutting the lens, which eliminates the problems of lens edge breaking and generation of multiple eccentric optic axes caused by excessive cutting pressure. In a final phase of grinding, the motor speed is slowed down for grinding the lens with low speed in order to eliminate the problems of scratches caused by high speed grinding and thus leading to polishing-like grinding result. By means of this method and the associated devices, the lens production efficiency is raised up without causing lens edge damage and generation of multiple eccentric optic axes.

Title: Power supply device
Inventor: IWATA KATSUMI
IPC: F23Q3/00
Filed: 2000-07-07
Granted: 2002-01-11
Abstract: Where an appliance which utilizes dry batteries as a power supply does not permit replacement of batteries, it is connected to a dummy battery connected to an external battery case via an extension cord. The dummy battery alone is received in a dry cell receiving portion of the appliance. Therefore, if the extension cord is inadvertently pulled, the dummy battery may slip from the dry cell receiving portion to result in poor electrical contact. Hence, in this invention, retaining plates 31a are formed on electrodes 31 of the dummy battery 3. The retaining plates 31a engage fixed electrodes in the dry cell receiving portion so as to prevent slippage from the dry cell receiving portion. Further, since the direction of pulling of a connector 40 is different from the direction of pulling of an extension cord 4, even if the extension cord 4 is pulled, the connector 40 will not, become detached.
