Title: Objective lens actuator
Inventor: YAJIMA MASATOSHI
IPC: G11B11/105
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To enhance driving sensitivity and to reduce a self-inductance component of a coil in an objective lens actuator used for an optical disk device. SOLUTION: This actuator is composed of a yoke 12 arranged opposite to a magnet 3 and coils 6a and 6b wound around the yoke 12 in the biaxial direction, and the center 12a of the yoke 12 in its thickness direction is positioned on the magnet 3 side by more than at least the thickness of the yoke 12 against the winding center 6c of the coils respectively. Consequently, the driving sensitivity is enhanced, and self-inductance is reduced while a phase lag angle is made small to prevent the coils from heating up due to electric noise of a driving current, and hence the focus control and tracking control can stably be performed following variations of a wobble and an eccentricity, etc., of a disk.

Abstract: PURPOSE:To prevent the contamination of the surface of a semiconductor piece due to corrosion of solder, by processing the removal of the contaminant on the surface of the soldered semiconductor piece, thereafter washing the surface with pure water, in which carbon dioxide gas is dissolved. CONSTITUTION:In a washing tank 1, pure water is introduced through a water feeding port 2 and overflowed from the upper part. The washing tank has a carbon-dioxide-gas introducing pipe 3. Bubbles of CO2 gas are discharged into the pure water 4 through many holes. A high voltage rectifier element 5 is put in a container 6, which is further placed in the washing tank for immersion. Since the carbon dioxide gas, which is jetted through the introducing pipe 3, is dissolved in the pure water 4, the lead on the surface of the solder of the rectifier element 5 becomes lead carbonate. It does not becomes passive and the lead is not eluted in the pure water. Therefore, lead ions are not attached to the surface of the semiconductor piece of the element 5. Thus, the contamination of the surface of the semiconductor piece due to the lead ions is prevented, and the highly reliable device can be obtained.

Abstract: PURPOSE: To prevent maloperation due to exciting rush current by judging exciting rush current  and trouble current.  
     CONSTITUTION: The difference between sampling value before sampling period and the sampling  value at the present time is taken out by the filter 1 and then differential current value is calculated by the arithmetic portion 2. The negativity and positivity of sampling value at the present time  are judged by the judging portion 3. In the case of negative value, counting is made by the counting portion 6, and if the results of the counting portion exceed a certain value, the judging portion  7 judges it as exciting rush current and then the output of the protective relay for transformer is  locked by the block 8. If the judged result is below a certain value, the judging portion 9 judges  whether the output of the arithmetic portion 2 is or not below a certain value. Then, if it is above  a certain value, a breaking command is sent to breaker at the block 10 by judging it as a trouble  in transformer. If the output of the judging portion 9 is below a certain value, it is judged as  sound state and it is waited until the following offering at the block 11. When the result of the  judging portion 5 is other than negative, the results of the counting portions 6 and 16 are cleared  at the blocks 12 and 13, and following treatment is made at the judging portion 9.
