Patent JP-H03136015-A (JP)
Title: Device for converging, mixing, or integrating light beam
Inventor: ISHIKAWA TOSHIAKI
IPC: G02B5/10
Filed: 1989-10-23
Abstract: PURPOSE:Not only to converge laser light of one color, but also to converge and mix many laser light beams which oscillate with various wavelengths by using an elliptic reflecting mirror. CONSTITUTION:A couple of reflecting mirrors which are sectioned in the shape of an ellipse or part of an ellipse and have rotary surfaces centering on the major axis of the ellipse are arranged on the major axis opposite each other so that two focuses F1 and F2 are on the major axis. Namely, laser light beams 1 and 2 are made incident from outside the ellipse so as to pass one of the two focuses of the ellipse, e.g. F2 since light which is emitted from one focus of the elliptic mirror is converged on the other focus after being reflected by the elliptic surface. Consequently, the laser light beams 1 and 2 are reflected many times and then converged in the direction of the major axis of the ellipse. Consequently, the device which enables any of the convergence, mixing, and integration of light with the relatively simple constitution, namely, using the couple of reflecting mirrors is obtained.

Title: Method for working ni-ti alloy wire
Inventor: MATSUO AKIRA
IPC: C22C19/03
Filed: 1994-11-09
Abstract: PURPOSE: To suppress the reduction in the yield due to the surface crack in realizing the fine wire made of Ni-Ti alloy. CONSTITUTION: The preliminary working to thin the tip part to be worked of the wire is achieved in thinning the wire through the rolling by rolls or drawing by dies of the Ni-Ti alloy wire. The very tip surface at the beginning of the working of the wire is a free surface in terms of the stress in the rolling to thin the wire by finely forming the tip part of the Ni-Ti alloy wire, and the tip part is likely to expand freely during the working free from the external restraint, and is likely to be cracked therefor. Once the crack is generated, the expansion of the crack is passed in thinning the wire in the subsequent several operations.  When the very tip part is preliminarily chamfered to make the thickness of the preliminarily worked part smaller than the roll intervals, the tip part of the wire is projected rearward of the contact point between the rolls, and only the stress mainly in the axial direction is applied to prevent the generation of cracks.

Title: Magnetic recording medium
Inventor: YAMASHITA MASAMI
IPC: G11B5/706
Filed: 1985-12-10
Abstract: PURPOSE:To securely stick a magnetic material to a substrate and to remarkably improve the coercive force of the magnetic material by using a chromium film as an underlying layer. CONSTITUTION:The underlying layer essentially consisting of chromium is provided on the substrate and the magnetic layer consisting of a cobalt-platinum alloy is provided on the underlying layer. The thickness of the underlying layer consisting of the chromium film is preferably in a 10-10,000Angstrom  range. The effect of improving the coercive force is low and the ratio of the fluctuation of the coercive force to the change of the thickness is high if the thickness is <=10Angstrom . The magnetic recording medium having the stable coercive force is then not obtainable. The coercive force is substantially high and the fluctuation of the coercive force as compared to the change of the thickness is relatively small if the thickness of the chromium layer is within the 100-10,000Angstrom range and therefore, said range is more particularly preferable in general. There is no particular improvement of the coercive force if the chromium layer is made thicker than the specified range. In addition, such is uneconomical.
