Title: Spectacle with spring hinge and method for expanding temple
Inventor: HORIKAWA KAORU
IPC: G02C5/22
Filed: 2001-05-02
Abstract: PROBLEM TO BE SOLVED: To provide a spectacle with spring hinge which is capable of detecting the excess rotation of a temple above the limit thereof in advance and prevents the temple from being broken with respect to a bracket. SOLUTION: The temples 4 are connected with spring hinges 3 fitted to the respective brackets 2 of the rim frames in a way that the temples 4 are finely slidable in the length direction and are energized towards the bracket sides. The spring hinge 3 is provided with a means for preventing the temples from excessively rotating outwardly, at the interior thereof. As the outwardly rotated angle of the temple increases, the contact point between the abutting end faces of the bracket 2 and temple 4 is displaced away from the axis of the spring hinge. Thus, the excess rotation of the temple above the limit thereof can be detected in advance, so that the breakage of the spectacle can be prevented and a spectacle, which is too large for the face of a wearer, is not selected.

Title: Method of controlling speed of actuator
Inventor: IKEDA TAKESHI
IPC: H02P7/29
Filed: 2001-05-17
Abstract: PROBLEM TO BE SOLVED: To make a speed-controllable actuator inexpensive. SOLUTION: The driving duty ratio Dm and the current Im when the actuator is driven at a fixed speed (target speed) are mapped in advance. At the time of driving a motor, the driving duty ratio Dm is compared with a discriminated driving duty ratio Dh found from the map in accordance with the detected current Im of the motor and, when Dh>Dm, control is performed to increase the speed of the actuator by increasing the driving duty ratio Dm at a prescribed rate (ΔDm). When Dh<=Dm, the control is shifted to constant-speed control by judging that the speed of the actuator becomes the target speed or higher. Therefore, when the motor is used, the control can be shifted from acceleration control to constant-speed control without using an expensive rotation sensor and the speed-controllable actuator can be made less expensive.
