Abstract: PROBLEM TO BE SOLVED: To generate feedforward control data while subjecting an optical disk to high-speed rotation. SOLUTION: A search signal which stepwise increases or decreases a distance in order to bring an objective lens 3 close to a recording surface of the optical disk 1 is outputted from a focus search signal output part 10. When an actuator 2 brings the objective lens 3 close to the recording surface or takes the same away from the recording surface with an actuator driving signal from a driver 4, an FE signal check part 11 monitors the change of FE signal and holds the search signals when the change such as S shape appears and when the change disappears on a first data holding part 12 and a second data holding part 13 respectively. A feedforward control data generating part 14 generates a signal of the feedforward control data from the said held search signals.

Title: Key board unit using plate spring
Inventor: KUMANO SHINJI
IPC: G10H1/34
Filed: 2000-05-22
Abstract: PROBLEM TO BE SOLVED: To eliminate an influence of camber of a plate spring even when the spring is cambered onesides in a free condition. SOLUTION: Compression force is applied longitudinal-directionally in both ends of a plate spring 1, and the both ends are supported by support mebers 2, 3 respectively. The both ends and one position of a longitudinal-directional middle part of the plate spring 1 serve as nodes N1-N3, and the spring 1 is deformed into an S-shape to constitute loops respectively between the one position of the longitudinal middle part and the both ends. The plate signal 1 energizes thereby a pair of the support parts 2, 3 to a longitudinal-directional outside. Even when the spring 1 is cambered in a free condition, an influence of the camber is moderated by the node N3 to generate constant energizing force all the time.  The plate spring 1 formed into the S-shape enlarges energizing force toward its outside by the two cambers in upward and downward directions, to provide necessary energizing foece even when the spring 1 is thinned.
