Filed: 1981-02-17
Abstract: PURPOSE:To stably measure a liquid level of a high temperature liquid extending over a long period by simple constitution, by providing a gas storage chamber consisting of a rise part, on a pressure takeout port provided on the side wall of a liquid tank. CONSTITUTION:In pressure takeout ports 3, 4 provided on a side wall 1 of a liquid tank, the takeout port 4 provided at a liquid sink position is provided with an extending part 4a on its side, and on the extending part 4a, a rise part 4b forming a gas storage chamber 5 is provided. Gas in a liquid to be measured 2 is caught by a catching member 11 and collects in the chamber 5. Accordingly, the pressure of the takeout port 4 position operates on a pressure measuring diaphragm 6 through gas in the chamber 5, and a liquid level (h) can be grasped by differential pressure between this pressure and pressure of the takeout port 3. Also, the diaphragm 6 is out of contact with the liquid 2 directly, and a transfer route of heat of the liquid to a differential pressure takeout and detection terminal 8 becomes mainly the ringlike rise part 4b, and it is possible to prevent silicone oil 7 from rising to a high temperature.

Title: Sealing method of package and its construction
Inventor: KANNO HIDEYUKI
IPC: H03H9/19
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To perform vacuum sealing without the need of a vacuum chamber having a large capacity by a method wherein a through-hole is provided in a part of a cover or a container and sealed up in vacuum by a sealing material after the cover is mounted on the container. SOLUTION: A through-hole 16 is drilled in a part of a cover 10 and a solder 17 as a sealing material is arranged around the through-hole 16. Then, the cover 10 is welded on a container 7 to form a package. As the vacuum tank is evacuated after the package is place in it, the inside of the package is also evacuated simultaneously. In this state, when electronic beams are radiated to the solder 17, the molten solder 17 flows into the through-hole 16 and seals it up, thus the package of a crystal oscillator 8 is complete with the inside of the package kept vacuum. Therefore, welding of the cover 10 on the container 7 can be carried out in the atmosphere without the need of a special welding device, so that production costs of a surface mounting type crystal oscillator can be cut down.
