A titanium, .alpha. titanium alloy or (.alpha.+.beta.) titanium alloy material is hydrogenated in an amount of 0.02 to 2% by weight. If necessary, the hydrogenated material is subjected to pretreatment [i.e., heated above 700.degree. C. (.beta. transformation point)] and/or working (i.e., working at 450.degree. to 950.degree. C., or temperatures above .beta. transformation point and below 1100.degree. C.). The material is then aged at 10.degree. to 530.degree. C. or 10.degree. to 700.degree. C. (in the case of working at temperatures above .beta. transformation point), and finally dehydrogenated and recrystallized to prepared a material having a fine equiaxed microstructure.

摘要： The ferritic stainless steel sheet involves a problem that the ridging is likely to generate at the forming step, such as the deep drawing step. The ridging is believed to be caused by a band structure in the hot rolled band, which structure exerting an influence on the formability of a cold rolled sheet. The ridging is prevented in the present invention by means of the combination of the three technical measures: incorporating aluminum into a ferritic stainless steel; heating a slab to a low temperature of 1200.degree. C. or less; and, carrying out a drastic hot rolling of at least one pass with the draft of 20%/pass or more. As a result of these technical measures, the structure of a hot rolled band is made and uniform and thus both the formability and anti-ridging property are enhanced.

C., performing subsequent cooling to a level not higher than 200.degree. C. at such a cooling rate that a chromium depletion layer, which causes a gold dust defect, is not formed around the chromium carbonitride. Single cold rolling and recrystallization annealing are carried out in combination until the thickness is reduced to the gauge thickness.

摘要： The present invention provides a high frequency heating apparatus having a structure, which can be mounted/dismounted an air-exhausting grille without any tools. In this apparatus, an air-exhausting grille is arranged by that a fixing claw portion having a bent Z-shape, a fixing hooking portion having a concave notch, and a magneto joint plate are arranged, whereas a main body located opposite to the air-exhausting grille is arranged by that a slit hole, a hooking flange, and a magneto fixing plate are arranged. As a result, since the magneto joint plate is absorbed with the magneto fixing plate to be fixed with each other, the mounting/dismounting work capability of the air-exhausting grille can be improved without using the tool in a simple manner, and furthermore, a clean cooking appliance can be secured, while the cooking appliance can be readily cleaned.

摘要： An autofocusing zoom lens, comprising a half-mirror prism and a sensor capable of detecting light in conjunction with the half-mirror prism, is formed by inserting the half-mirror prism between the front-lens and rear-lens groups of the master-lens groups of the lens system. The insertion of the half-mirror prism has the advantages that the back focus may be shortened, the lens aperture need not be enlarged, and that the lens length in effect may be shortened. Additional use of a sensor-related lens makes autofocus available even when the angle of exit pupil of the imaging optical system is small.
