摘要： PROBLEM TO BE SOLVED: To manufacture a bellows of large diameter through hydrostatic forming by building a liner into a plurality of split dies, mounting a metallic stock tube inside, applying the hydraulic pressure thereto to expand the metallic stock tube, detaching the liner, axially applying the pressure to the die while re-applying the hydraulic pressure, and extruding the metallic stock tube into the gap between split dies. SOLUTION: A liner 53 is built in, split dies 8, 52 are arranged, and a metallic stock tube 1 is set inside. An upper end part 1a and a lower end part 1b of the metallic stock tube 1 are clamped to an upper die 51a and a lower die 5b in a sealed condition. The pressurized medium is fed to a hydraulic pressure chamber 10 of the metallic stock tube 1, and the metallic stock tube 1 is expanded in the arrow direction. The hydraulic pressure is fed to the hydraulic pressure chamber 10 of the metallic stock tube 1, and the metallic stock tube 1 is expanded in the arrow direction. The hydraulic pressure in the hydraulic pressure chamber 10 is removed, and the liner 53 is detached. The metallic stock tube 1 is inserted in the split dies 8, 52, and the pressure in the axial direction is applied to the upper die 51a while applying the hydraulic pressure to the hydraulic pressure chamber 10. The split dies 8, 52 are pressed in the axial direction and the metallic stock tube 1 is extruded between the split dies 8, 52.

摘要： PURPOSE:To carry a sample between each processing device under environmental control and more specifically keep a crystal structure, an element composition and a bonding state of the sample, keeping its state directly after it is prepared or dynamically process the changes in the process. CONSTITUTION:This sample processing device comprises a transfer chamber 23 which houses a removable sample holder main body 1 at the tip of a transfer rod 9 and transfers the sample under the control of sample temperature in a vacuum state or in a gas purge state between a film formation device and an evaluation device, joint parts between each of film formation devices and a thin film device a sample heating device, a sample slanting mechanism and a battery type portable ion pump 24 or the like. Since this device is connectable to various processing devices and the evaluation device more flexibly, this device can be adopted for online inspecting process conditions in a preparation process line for product devices including Si-VLSI. This device can be separately used as a sample carrier device under environmental control as well.

摘要： PURPOSE:To restrain the temperature of a substrate from being raised and to keep the temperature of the substrate definite during an etching operation by a method wherein a plasma treatment apparatus is used, the surface of the substrate is heated to a temperature which is equal to or higher than that of an electrode, a high frequency is applied to the electrode and the substrate is treated. CONSTITUTION:An oxide film 3, a copper film 4 and a mask 5 which is composed of an oxide film on which a pattern has been transcribed are formed on the surface of a silicon wafer 2. A polyimide film 6 is formed on the rear of the silicon wafer 2. A substrate 1 is placed inside an apparatus. The heating air from a heater 16 for gas heating use is supplied to a heating-gas passage 13 inside an electrode 12; the temperature of an electrode surface plate 11 is kept. Silicon tetrachloride as a reaction gas is supplied to the inside of an etching chamber 10 which has been evacuated to produce a vacuum; the pressure of the etching chamber is adjusted. Electric power is supplied to an infrared lamp 28 from an infrared-lamp power supply 27; the substrate 1 is heated. When the substrate 1 reaches a prescribed temperature, the output of the power supply 27 becomes zero by a signal from a temperature indicator 23; electric power is supplied to the electrode 12 from a high-frequency power supply 26.

摘要： PURPOSE:To prevent the occurrence of a seizure trouble and a breakage trouble, by a method wherein a seal ring is changed through a change in the inner pressure of a shaft sealing part, and in case the inner pressure is a positive pressure, pumped up water can be fed to the shaft sealing part, and in case it is negative pressure, lubricant can be fed to the shaft sealing part. CONSTITUTION:In case a pressure in a stuffing box 2, i.e., the inner pressure of a shaft sealing part is a positive pressure, a positive pressure P1 is exerted on the under surface of a seal ring 3, i.g., an end surface 3f, and it is deformed until it is forced into contact with the outer peripheral surface of a rotary shaft 6 to form a shaft sealing part 12, and an end surface 3g, located opposite to the end surface 3f, is brought into contact with a cover plate 10 to enclose a lubricant chamber 4. In this case, the shaft sealing part 12 is lubricated by pumped up water in the stuffing box 2. In case the inner pressure of the shaft sealing part is a negative pressure, the seal ring 3 is attracted by means of a negative pressure P2, the end surface 3g is deformed until it is brought into contact with the outer peripheral surface of the rotary shaft 6 to form a shaft sealing part 13, and is brought into contact with the cover plate 10. In this case, a lubricant 11 in a lubricant chamber 4 is pressed by an atmospheric pressure introduced through an air hole 2f and is fed to the interior of the shaft sealing part 13 to perform excellent lubrication.
