Title: Microwave oscillator
Inventor: SHINKAWA TAKAO
IPC: H03B9/14
Filed: 1981-03-05
Abstract: PURPOSE:To minimize a decrease in the Q factor of a resonance circuit by reducing the loss of a microstrip line by removing a dielectric substrate which constitutes the microstrip line. CONSTITUTION:Part of a dielectric substrate 1 is removed to provide a cut part 21. A conductor plate 22 is provided across the cut part 21. The conductor plate 22 and a ground conductor 3 form a microstrip line which does not include a dielectric except air mutually. Then, when a voltage is applied to a bias terminal 11, an oscillation output having a frequency determined by the resonance frequency of a dielectric resonator 7 appears at an output terminal 9. Consequently, the Q factor of the resonator 7 is minimized to obtain the microwave oscillation output which has sufficiently high frequency stability.

Title: Method for smelting extra-low carbon steel
Inventor: YAMAGUCHI KIMIHARU
IPC: C21C7/10
Filed: 1993-02-19
Abstract: PURPOSE:To stably smelt a large quantity of an extra-low carbon steel by adding a deoxidizer while holding the oxygen concn. in a molten steel to a prescribed value after vacuum-decarburizing to a prescribed carbon concn. in the steel by using hydrogen in a vacuum degassing device. CONSTITUTION:Into a ladle 2 for holding a molten low carbon steel 3 containing about 300ppm [C] produced in a converter, circulating tubes in the degassing vessel 1 are dipped. Atmospheric gas in the degassing vessel 1 is sucked with a vacuum pump, and while blowing H2 and Ar from a tuyere 4 for circulating gas, decarburization-refining is executed. Then, at the time of decarburization- refining to the prescribed carbon concn. (< about 20ppm), the treating pressure is increased and the vacuum-decarburization is practically interrupted. After dissolving the hydrogen to the prescribed hydrogen concn. (about 5ppm) in the molten steel, a secondary vacuum-decarburization is started, and while holding the oxygen concn. in the molten steel to >=200ppm, the deoxidizer is added from a feed device 5. Thus, the non-metallic inclusion is produced and the generation of nuclei of bubbles containing CO is facilitated and the decarburization is promoted, and the extra-low carbon steel containing < about 10ppm for [O] is obtd.

Abstract: PURPOSE:To improve safety in the captioned mechanism for lumber or the like by providing, at the position where there occurs slackening of a sub-line, a hung sub-line support means for supporting/releasing a sub-line under rotation in contact with a carrier. CONSTITUTION:There is provided a support member 3 hung by a rope C at the position of a slackened sub-line B for supporting a main line A at a support part 1. Besides, a receiving shaft 9 is attached at the tip of a sleeve 5 energized by a spring 6 through saw teeth so as to be freely rotated one tooth by one tooth. With this arrangement, as a carrier D reaches the position of the slackened sub-line, the sleeve 5 arises in rotation against the spring 6 under abutment between an upper pushing plate 12 and an upper blade 8, which rotates the saw teeth (a), (b) by one tooth thereby supporting the sub-line by the receiving shaft 9. The abutment between an lower pushing plate 13 and a lower blade 7 further rotates them by one-fourth tooth to thereby release the sub-line from the receiving shaft 9. By supporting the slackened sub-line in such a way, it is possible to improve the safety.
