Abstract: PURPOSE:To enhance the forming accuracy of a thin wall pipe and to improve the quality and the yield by using a die to which a porous body having a caliber shape is attached, for forming an open pipe. CONSTITUTION:Porous bodies 25, 26 are fitted to the wall surface of the working surface side of dies 21, 22, and formed as one body. Subsequently, gas such as air, etc., is supplied by prescribed pressure through pipings 27, 28. To the upper porous body 25, and the lower porous body 26, a projecting caliber 25a and a recessed caliber 26a are worked continuously to a downhill shape, etc., so that a band plate 1 is formed successively from a flat shape to a cylindrical shape, respectively. In order to give advance force to the band plate 1 worked by a forming device, a draw gear is provided in the rear of a squeeze roll, inserted and held by belts extended and turned in the longitudinal direction of the action surface of the porous body having a semicircular caliber shape and an open pipe is drawn out of the forming machine. The belt is pressed against the surface of a thin wall pipe formed by pressure of air blown out of the porous body and gripping force is generated and the thin wall pipe can advance.

Abstract: PURPOSE:To suppress formation of abnormal carburization structure by specifying the contents of C, Si, Mn, Cr, Al, N and Ni, Mo which are the basic components in a case hardening steel used for parts for structural purposes. CONSTITUTION:The case hardening steel is composed to contain, by weight, 0.1-0.4% C, <0.15% Si, <0.5% Mn, <0.35% Cr, <0.01% SolAl, and >=0.0045% N and to contain >=1 kinds of 0.2-5.0% Ni and 0.1-2.5% Mo and the balance Fe and unavoidable impurities. If necessary, >=1 kinds among 0.0003-0.005% B, 0.01-0.15% Nb, and 0.01-0.1% V are incorporated therein. Since the case hardening steel composed in such a manner is suppressed in the generation of the abnormal carburization structure even if subjected to high-temp. carburization hardening, said steel has excellent fatigue strength, rolling fatigue strength and wear resistance. In addition, the time for the carburization is shortened by the high-temp. carburization hardening.

Title: Semiconductor laser
Inventor: YOSHIKAWA TAKASHI
IPC: H01S5/00
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To contrive improvement and equalization of laser property, by thickening the current narrowing layer in a current narrowing region more than the thickness of the current narrowing layer in a current application region, and making the current narrowing layer in the current narrowing region an oxidizing layer, and arranging the current narrowing layer in the current application region not to be substantially oxidized. SOLUTION: A semiconductor laser has such structure that a middle layer 5 having an active layer 4 is interposed in the resonator comprising a lower distribution reflective mirror 7 and an upper distribution reflective mirror 2, and a current narrowing layer 3 is provided right above the middle layer 5. The thickness of this current narrowing layer 3 is 12 nm in, for example, a current narrowing region A, and 24 nm in a current narrowing region B. The current narrowing region A is oxidized with the lapse of time from the sidewall of a mesa 9, but when the oxidation reaches a current application region B, the oxidation ceases to progress because from there the thickness is thin at 12 nm, consequently only the current narrowing region A where the current narrowing layer 3 is thick is oxidized.  As a result, a laser excellent in equality where the properties such as threshold current, etc., are even can be obtained.
