Title: Optical pick-up device
Inventor: TOMIYAMA TAKAMICHI
IPC: G11B7/22
Filed: 1987-03-02
Abstract: PURPOSE:To stably execute focusing servo and tracking servo with frequencies in a wide band and to precisely form a titled device by forming a lens holding part which holds an objective lens with ceramics and forming other most part of the lens holding part with a synthetic resin. CONSTITUTION:The lens holding part 12 which holds the objective lens 28 of a two-axis driving body 11 where the objective lens 28 is provided is formed with the ceramics and the other most part 17 is formed by outserting the comparatively thin synthetic resin into the lens holding part 12. Since it is formed with ceramics, namely, the materials having high resonance frequency and the thin synthetic resin, the resonance frequency of the two-axis driving body can be made pretty high and the focusing servo and the tracking servo can be stably executed with frequencies in the wide band. For example, as for the part, where a coil is wound, of the two-axis driving body, that is, the part facing to a magnet for servo, etc., putting a fine gap, even pretty fine shape of the two-axis driving body can be precisely formed by the workability of the synthetic resin and the precision of a metal mold for formation.

Title: Laser welding body consisting of aluminum plated steel plate, and welding method
Inventor: MITSUYOSHI HIROSHI
IPC: B23K26/21
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To secure sufficient welding strength in welding an aluminum plated steel plate by using a laser beam. SOLUTION: If the ratio of aluminum component in a weld zone is 0.65 wt.% or less, a peeling breaking stress is obtained comparable to the tensile stress (27-28 kgf/cm<2> ) of the base material; if the ratio is 0.65 wt.% or above, the peeling breaking stress is smaller than the tensile stress of the base material. Thus, the aluminum component in the weld zone has bearing upon the tensile strength, with the welding strength improved as the contents of the aluminum component is less in the weld zone. In addition, in controlling such contents low in the weld zone for the purpose of obtaining a prescribed joining strength, the heat quantity of a laser beam is effectively increased per unit area by delaying the moving speed of a laser welding machine for example.

An access returning an optical pick-up device to the leading address of the first voice data is performed right after when the read-out of the second time is completed since an operator grasps in what position data to be replaced is recorded by the result of a previous monitoring at a time when the read-out of voice data of the second time is completed thereafter, voice data are replaced by reading- out voice data of the first time and performing a rewriting to a required part. Thus, a SYNCH-REC. operation is performed only with a single optical pick-up device.

Abstract: PROBLEM TO BE SOLVED: To make it possible to from a CdTe film in a low-cost gas and to reduce more the usage of the material for forming the CdTe film at lower cost by a method wherein a gas, which is generated by heating the material containing a CdTe and/or a Cd and a Te as its main component in an inert gas of a specified atmospheric pressure or higher, is transported to a heat-resistant substrate and the CdTe film is deposited on the substrate. SOLUTION: A gas, which is generated by heating a material containing a CdTe and/or a Cd and a Te as its main component in an inert gas of 0.5 atmospheric pressure or higher, is transported to a heat-resistant substrate and a CdTe film is deposited on the substrate. An exhaust valve 14 and a gas introducing cock 13 are turned on to hold the substrate in a sealed container 8 for 10 minutes and the interior of the sealed container 8 is filled with the inert gas. If the flow rate of the gas at this time is 20 liters/minute or thereabouts, that suffices to fill the interior of the container 8. After this, the cock 13 and the valve 14 are turned off in this order to keep the internal pressure in the container 8 at roughly one atmospheric pressure.  A temperature history is applied to a carbon plate 6 for material heating use and a carbon plate 7 for substrate heating use by a temperature controller 18 for material heating use and a temperature controller 19 for substrate heating use.
