Abstract: PROBLEM TO BE SOLVED: To modify the airtightness of an electronic component vessel of a hermetic structure, wherein the vessel is constituted by seam-welding a ceramic container, which is widely used, to a metal cover, and moreover, to make the unit cost of the vessel low. SOLUTION: A metallizing treatment is performed on the welding part of a recessed ceramic vessel 1 instead of a seam weld sealing, a metallized film 2 is formed on the welding part, a nickel-plated film is formed on the film 2, and moreover a gold- plated film 6 is formed on the nickel-plated film, whereby the formation of a seal ring consisting of a Kovar (R) material can be omitted, while a nickel-plated film is formed on the welding surface of a metal flat plate, a cladding treatment 7 of a silver solder is performed on the nickel-plated film and after that, the container 1 and a metal cover 3 obtainable by a method, wherein the metal flat plate is cut and is molded into a prescribed size, are welded together through a seam welding.  Thereby, with the material cost of the container 1 and the cover 3 are reduced, the fused surface of the container 1 with the cover 3 surface-contacts with the cover 3 by the omission of the formation of the seal ring. As a result, an electronic component vessel succeeds in taking large a seal path and the proper airtightness as well as the electronic component container being also improved.

Filed: 1989-05-29
Abstract: PURPOSE:To prevent skew distortion of a reproducing picture in the case of a short recording interval by changing a response characteristic of a servo control means for a rotary drum during a prescribed short period immediately before commencing intermittent movement and shortening the convergent period of jitters of a rotary magnetic head. CONSTITUTION:A frequency changeover pulse C is supplied from a timing control circuit 50 to a switch 34 immediately before a magnetic tape MT is intermittently moved, and an oscillating frequency of a reference oscillator 31 is changed from fsc over to, for instance, 1.02fsc by this changeover pulse C only for a short period of 'Hi'. Consequently, an output of a divider 35, i.e. a frequency of a reference signal Sref of a phase servo circuit 21 is also increased suddenly by, for instance, 2% only for this short period. Then, by such a sudden increase of the frequency of the reference signal Sref, the response characteristic of a drum servo system 20 is changed. By this method, the rotation of the magnetic head at the time of intermittent frame recording is quickly stabilized, and the skew distortion of the reproducing picture in the case of a short recording interval is prevented.

Filed: 1980-09-30
Abstract: PURPOSE:To obtain power with a constant speed and a constant direction regardless of variation in line frequency, by changing over the direction of rotation according to the variation in the line frequency and changing the speed reduction ratio according to the rotational direction. CONSTITUTION:When the line frequency of an electric powr source 1 is 50Hz, a frequency discriminating circuit 6 energizes a relay 4 which operates by positive rotation and closes ite contact point 4a. Then, a motor 2 turns positively at a number of rotation, n1, and the output shaft of a reduction gear 7 rotates, for instance, clockwise at N1=n1/50 based on the reduction ratio 50. If the line frequency is 60Hz, the relay 5 which operates by negative rotation is energized, and the motor 2 rotates in th opposite direction at the number of rotation, n2 (n2=1.2Xn1). Then the output shaft of the reduction gear 7 rotates by the number of rotation, n2=n2/ 600=1.2Xn/60=n1/50=N1 based on the reduction ratio, 60, in other words, by the same number of rotation as when the line frequency is 50Hz.
