Title: Modified aluminum alloy for casting, and cast member
Inventor: FANG QUE-TSANG
IPC: B62D29/00
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy suitable for use in mold casting operation by providing a specific composition consisting of Mg, Si, Mn, Fe, Ti, and the balance essentially Al with accompanying elements and impurities. SOLUTION: The alloy has a composition containing, by weight, about 2.5-6.5% Mg, <about 0.5% Si, about 0.5-1.4% Mn, <about 0.5% Fe, and <0.15% Ti. An automobile frame member, obtained by casting this alloy, causes no serious breakage and has high energy absorbing power and, further, can be easily recycled because it does not contaminate the flow of a casting alloy composed of recycled material. Moreover, because this alloy requires neither solution heat treatment nor hardening nor aging treatment, an equipment cost for heat treatment is low and the necessity of large floor space is obviated, and heat treatment operation costs can be reduced. Accordingly, deformation of parts can be minimized, treatment capacity can be improved, and the necessity of troublesome waste water treatment can be obviated.

Title: Optical measuring apparatus and manufacture thereof
Inventor: IKUTA SAKAE
IPC: G01R15/24
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent the accuracy from lowering due to temperature by constituting a box for containing a polarization part for converting an incident light into a linearly polarized light and a detecting part for decomposing a turned linearly polarized light into an orthogonal component as an outer box using a plurality of identical members. SOLUTION: Light from a light source passes on a transmission fiber 71 and enters into an optical system containing box 4 and converted through a polarizer 34 into a linearly polarized light before entering again into the optical system containing box 4 with the plane of polarization being turned in a sensor 2. X and Y components are taken out by two analyzers 35 and passed on receiving fibers 72, 73 for X, Y components and detected at a light receiving section before an optical data is processed at a signal processing circuit. The optical system containing box 4 is constituted of three identical compositional members 41, 42, 43 having identical coefficient of thermal expansion. Consequently, shift of the optical axis due to temperature variation can be suppressed.  The polarizer 34 and the analyzer 35 employ wire grid type elements in order to prevent the accuracy from being shifted due to thermal expansion thus preventing the accuracy from being varied due to variation of the ambient temperature.
