摘要： The rotary flat membrane disk is constructed in which circular membranes are stretched at both sides of a disk. The disk and the membrane are bonded to each other over the entire periphery by a peripheral bonding part, and they are also bonded to each other by a plurality of partial bonding parts arranged inside the peripheral bonding part. The partial bonding parts are formed like dots of 10 mm in diameter, and are arranged at every 30 degrees on circles of 500 mm and 600 mm in diameter.

摘要： An evacuation apparatus and method using a turbomolecular pump having a rotor provided with a plurality of rotor blades and a spacer provided with a plurality of stator blades so that gas molecules are sucked in from a suction port, compressed and discharged from an exhaust port of the turbomolecular pump is disclosed. A heat exchanger is provided at the suction port side of the turbomolecular pump to freeze-trap gas molecules from being cooled by a helium refrigerator.The gate valve is disposed upstream of the heat exchanger and is provided in a suction pipe which extends between the vacuum vessel and the turbomolecular pump. In exhausting the vacuum vessel, the gate valve is opened and, in this state, the turbomolecular pump and the helium refrigerator are run. During regeneration, the gate valve is closed, the turbomolecular pump is run, and the heat exchanger is heated by means of a heater or by operation of the helium refrigator being suspended, thereby sublimating molecules freeze-trapped in the heat exchanger.

摘要： A projection type display apparatus employing a liquid-cooled cathode-ray tube apparatus that copes with the leakage of cooling liquid. The projection type display apparatus employs a liquid-cooled cathode-ray tube apparatus provided with a liquid-cooling unit in which cooling liquid to cool the front panel of a cathode-ray tube is sealed. A tray is provided on the lower side of the liquid-cooling unit in the liquid-cooled cathode-ray tube apparatus to prevent the leaked cooling liquid from dripping onto a circuit board, a high-voltage wiring, and the like.

摘要： A rotary shaft is inserted to a tank through a hole formed in a wall of the tank. A casing is provided outside the tank, and the rotary shaft is supported by a bearing arranged in the casing. The casing is watertightly connected to the wall including the hole through a flexible joint. Seal members are arranged in the casing to seal the clearance between the rotary shaft and the casing. A sleeve is fitted on the rotary shaft so that the sleeve is watertightly in contact with at least one of the seal members, and the sleeve can be moved along the rotary shaft to change the seal member in contact with the sleeve. The bearing and the seal member are not affected by the deformation of the tank since the flexible joint connects the tank and the casing, and the rotary shaft can rotate smoothly while securing high sealing quality. The alignment of the axes of the bearing and the hole in the tank can be easy since the bearing is provided outside of the tank, and thus assembly and maintenance of the structure are easy. The tank can have relatively low strength since the tank has not to support the rotary shaft with the bearing; thus the structure can be compact and the cost can be reduced.
摘要翻译： 旋转轴通过形成在罐的壁中的孔插入罐中。 壳体设置在罐外部，旋转轴由布置在壳体中的轴承支撑。 壳体通过柔性接头与包括孔的墙体水密地连接。 密封构件布置在壳体中以密封旋转轴和壳体之间的间隙。 套筒安装在旋转轴上，使得套筒与至少一个密封构件水密地接触，并且套筒可以沿着旋转轴移动以改变与套筒接触的密封构件。 轴承和密封件不受罐的变形的影响，因为柔性接头连接罐和壳体，并且旋转轴可以平稳地旋转，同时确保高的密封质量。 由于轴承设置在油箱外部，因此轴承的轴线与油槽中的孔的对准可以很容易，因此容易组装和维护结构。 坦克可以具有相对较低的强度，因为坦克没有支撑带轴承的旋转轴; 因此结构可以紧凑并且可以降低成本。

摘要： A turbomolecular pump having a rotor provided with a plurality of rotor blades and a spacer provided with a plurality of stator blades so that gas molecules are sucked in from a suction port, compressed and discharged from an exhaust port. The pump further has a heat exchanger provided inside the suction port, the heat exchanger being connected to a refrigerator through a refrigerant pipe and a gate valve provided on the upstream side of the suction port. Gases having low molecular weights, particularly water vapor, are freeze-trapped on the heat exchanger. Thus, it is possible to efficiently exhaust gases having low molecular weights, particularly water vapor, and hence to obtain a high vacuum of good quality. In addition, it is easy to start and suspend operation of the system and possible to run it on a continuous basis.
