Title: Optical recording and reproducing device
Inventor: NAKAMURA TOORU
IPC: G11B7/125
Filed: 1984-04-20
Abstract: PURPOSE:To maintain a satisfactory servo action in the recording and reproducing modes by condencing light beams given from light sources independent of each other on an information recording medium after synthesizing these beams into the same optical axis and detecting only the reflected light given from a specific light source having a fixed level of output light to perform the servo control. CONSTITUTION:Semiconductor lasers 8 and 9 have the same light emitting wavelength and set in the polarizing directions vertical and parallel to the paper surface respectively. The beams of lasers 8 and 9 are converted into parallel beams by a collimator lense 2 and synthesized into the same optical axis through a half mirror 5 and a polarized beam splitter 10. This synthesized light is condensed on an information recording medium 4 by an objective lens 3 in the form of light spots independent of each other. Only the reflected light sent from the laser 9 is made incident on a photodetector 7 via an optical device 6 for detection of error signal. Thus both focus and tracking errors are detected between the lens 3 and the medium 4. The laser 9 is always kept at a fixed level of optical output to maintain a satisfactory servo action in both recording and reproducing modes.

Title: Magnetic shielding body
Inventor: IMANAGA KATSUHIRO
IPC: H05K9/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress heat generated by a current, which is made to flow through the interior of a shielding body, by a method wherein a conductor is divided into a plurality of rectangular shapes or rectangle shapes and is constituted in a state that the divided conductors are assembled into one solid body in a state that the divided conductors are insulated from each other. SOLUTION: As the example of a magnetic shielding body applied to a magnetic shielding of a molten steel electromagnetic stirring device, which is installed in an iron manufacturing factory, the magnetic shielding body to be used is constituted into a structure, wherein a 6-mm thick magnetic shielding steel plate 1 is divided into four in a rectangular shape. Insulators 6, such as a Bakelite and a mica, are respectively applied or pasted on or to the respective end edge parts of the divided iron plates as an insulator in the gaps between the divided iron plates and the iron plates are fixed to each other. The important matter here is that when the conductor 1 is divided, the conductor 1 is divided into a plurality of rectangular forms or rectangle forms in such a way as the intersect the flow direction of a current, which is made to flow through the interior of the conductor.  That is, as the current can be divided more, the current is effective to a reduction in a calorific value. As the current, which is made to flow through the interior of the conductor, is proportioned to the area of the conductor, the smaller the area of the conductor is made, the more the current can be inhibited.

IPC: F16D43/02
Filed: 1980-06-17
Abstract: PURPOSE: To enable operation of an actuator for car door lock or the like with a limited working force by arranging a small motor to increase the reduction ratio  with a gear while a clutch is provided in such a manner as to be engaged even at a  low speed only at the time of being pivoted from the output shaft.  
     CONSTITUTION: In operation for a remote controle of a car door lock, the tip of a lever 22 is connected to a locking/unlocking lever of the door lock. When a motor 6 is rotated normally for locking, the rotation of a power shaft 4 is transmitted to a reduction gear 11 once reduced by a reduction mechanism 12. The power shaft 13 rotates in reduction mode. While the rotation of the power shaft 13 is transmitted to the clutch plate 14, the clutch plate 14 fails to be pivoted immediately due to a rotation checking force applied by a wire spring 16 and instead, a pin 17 pushes the ends of sliding elements 21 and 21. As soon as the sliding element 21 presses against the inner wall of a drum 24, the rotation of the power shaft 13 is trasmitted to a  trasmission shaft 23 by way of the pin 17, the clutch plate 17 and the drum 24 to  turn a lever 22.
