Inventor: YOSHIDA SUMI
IPC: C22F1/18
Filed: 1981-07-29
Abstract: PURPOSE:To obtain a zirconium base alloy of which the microstructure is improved and corrosion resistance is remarkably enhanced, in a method for annealing the Zr base alloy after hot and cold plastic workings, by applying solution heat treatment to said alloy prior to two times or more of final cold plastic workings. CONSTITUTION:After a predetermined alloying element such as Sn or Fe is dissolved in Zr, the obtained ingot is preheated to a beta region temp. and forged in order to mold the same. The next alpha- forging may be omitted because carried out in order to regulate a demension. In the next stage, said treated ingot is formed into a fuel rod coating pipe for a nuclear reactor by hot working and thereafter subjected to first solution heat treatment. This treatment heats the pipe from the temp. after final hot working to a phase or an (alpha+beta) phase and rapidly cools the same. After this treatment, treated pipe is further heated to the (alpha+beta) phase and cooled rapidly. Imperfect solution heat treatment is also effective. In the next stage, two times or more of final cold rolling and annealing are carried out but tne effect of the aforementioned solution heat treatment is not lost until a final material is obtained.

Title: Laser resonator
Inventor: KAWAGUCHI SHIGERU
IPC: H01S3/08
Filed: 1990-05-14
Abstract: PURPOSE:To enable a laser oscillator to have an output power in a lower mode as much as that in a multi-mode (higher order mode) without enlarging a resonator in length by a method wherein a beam diameter expander is provided between a laser excitation space and a mirror in a laser oscillator. CONSTITUTION:A laser beam 2 oscillated and amplified through a rear mirror 3 and an output mirror 4 is expanded in beam diameter from d1 to d2 through a beam expander 6a and pass through a laser excitation space. A transverse mode is specified through a mode selector 5. The laser beam 2 is emitted outside through the output mirror 4. At this point, when a transverse mode is set to TEM00 and an expansion ratio of the expander 6a is represented by M, M=d2/d1. That is, in a laser resonator, if a mode of diameter d1 is obtained, a mode of diameter d2 can be also obtained. Assuming that gain is uniform in spatial distribution, a laser output is proportional to the power of laser beam, so that the output ratio can be represented by a formula, (d2/d1)<2>=M<2>. Therefore, a laser output can be obtained M<2> times as much in a TEM00 mode by increasing a laser excitation space 1 in volume.
