Title: Heat treatment of copper base alloy
Inventor: SAWADA KAZUO
IPC: C22F1/00
Filed: 1980-05-24
Abstract: PURPOSE: To prevent a change in the characteristics such as the shape memorizing effect and the occurrence of cracks during heat treatment by rapidly cooling a hot β- brass type Cu alloy contg. a prescribed amount of Al while rolling it with low temp. rolls.  
     CONSTITUTION: A Cu alloy contg. 2W15wt% Al is refined, cast, annealed,  worked, and freed of a surface oxide film to form an Al-Cu alloy tape. This tape is heated to a temp. at which the alloy has a β-phase structure, and the heated tape is cooled while being rolled with low temp. rolls in which cooling water or the like circulates. Thus, an Al-Cu alloy sheet is obtd. No cracks occur in the sheet, and when the sheet is bent by 45° at room temp. and immersed in hot water, it returns to the original straight state owing to the superior shape memorizing effect.

Title: Optical pickup supporter
Inventor: YAMAMOTO HIROSHI
IPC: G02B7/00
Filed: 1983-04-20
Abstract: PURPOSE:To obtain an inexpensive optical pickup with light weight by connecting orthogonally two pairs of plate springs set in parallel to each other, and fixing an end of the plate spring rectangularly to a lens holder, and fixing the other end orthogonally to a main body supporting member of the optical pickup. CONSTITUTION:When an objective lens 1 is shifted toward the optical axis, the 2nd plate springs 4 and 4' are kept as they are without change. While the 1st plate springs 3 and 3' are kept in parallel and at the same time have displacements with vertual fulcrums a-a' and c-c' with the spring 3 and fulcrums b-b' and d-d' with the spring 3' respectively. In this case, both springs 3 and 3' have the same degree of displacement although they are folded with each other since the corresponding plate springs have an equal length. Furthermore these springs function to each other so as to maintain a quadrilateral at all times in a side view. As a result, the optical axis has not tilt although the lens 1 is shifted toward an arrow B1-B2. Thus it is always possible to keep the optical axis vertical to a recording pit.
