Title: Optical pickup
Inventor: NISHII KANJI
IPC: G02B7/28
Filed: 1983-04-20
Abstract: PURPOSE:To reduce the overall thickness of an optical pickup and at the same time to improve the record/reproduction characteristics by setting both the tracking and focusing driving coils at the same height as a lens barrel and adding the magnets in opposition to each other to both driving coils. CONSTITUTION:When a driving current is flowed to a focusing driving coil 16 based on the focus error signal detected by a focus error detecting circuit, the focus driving power acts in the ZZ direction between magnet units 23a and 23b by the Fleming's left-hand rule. As a result, the spring parts 26a and 26b of elastic support members 19a and 19b move toward ZZ and therefore an objective lens 13 has displacement in the ZZ direction. Thus the focus control is performed. For the tracking control, the driving power is generated in the XX direction between magnet units 18a and 18b by the Fleming's left-hand rule when a tracking driving current flows to tracking driving coils 17a and 17b. Thus the spring parts 26a and 26b move in the XX direction to perform the tracking control.

Title: Method for gas pressure welding of steel material
Inventor: ISHIKAWA YASUSHI
IPC: B23K20/00
Filed: 1982-04-30
Abstract: PURPOSE:To heat satisfactorily the joined part of steel material and form reinforcement of weld in an adequate state by forming a groove having a bottom wider than a single Vee groove on the outside surface in the joined part and a root part on the inside surface and heating the groove with a high temp. gas from the outside surface. CONSTITUTION:The part A in the groove part is a groove wider in the bottom than a single Vee groove and the part B is a root part to be welded tightly in the case of butting steel pipe P and P and welding the joined part thereof by gaseous pressure. When the joined part is heated with a high temp. gaseous flame from the outside surface, the high temp. gas arrives easily at the point (a) on the bottom side because the groove has the wide bottom, so that the part A of the groove and the root part, i.e., the part B can be heated effectively. The point C on the inside surface is thus heated quickly up to the adequate temp. for pressure welding. Only the metal in the part B serves mainly the reinforcement of weld for the inside surface and the formation of more than necessary resinforcement of weld on the inside surface is obviated.
