摘要:
A thermal insulator can change a heat insulation characteristic partially with a simple structure. The thermal insulator is divided into a plurality of parts in accordance with a temperature of a heat source which is insulated by the thermal insulator. The plurality of parts are formed of different honeycomb structures, respectively, so as to provide different heat insulation characteristics. The plurality of parts may be formed by different materials, or a shape or dimension such as a cell pitch of the honeycomb structure may be varied. Heat is collected from air within the honeycomb cells, and is transferred to other parts for heating.

A plating system is composed of a transfer device for performing transfer of a wafer, a plating unit and a washing/drying unit provided around the transfer device. Each unit is structured to be detachable from the plating system. The plating unit is divided into a wafer transfer section and a plating section by a separator, and atmosphere of each section is independently set.

An electronic/electric part used in a clean room in which the atmosphere is controlled to process a substrate in a semiconductor device industry, which contains a resin base material and additives added to the resin base material. The additives contain one or more materials selected from the group consisting of an anti-electrostatic agent made of a nonionic compound of a molecular weight of 350 or higher, an anti-oxidizing agent made of a phenolic compound of a molecular weight of 300 or higher, a lubricant, a plasticizer, a fire retardant, and a water repellent. The additives hardly releases gaseous organic substances from the resin base material under a condition where the part is used.

A heat-treating apparatus has a reaction vessel being adapted for performing a heat process for a workpiece to be treated and having a joint pipe portion and an outer pipe jointed to the joint pipe portion and of the reaction vessel. A sealing member is disposed between the outer pipe and the joint pipe portion. The sealing member has a relatively soft core member and a film harder than the core member. The film is disposed on the surface of the core member and has a heat resistance and a chemical resistance. Since the core member of the sealing portion has flexibility, it easily deforms corresponding to the shape of the sealing portion. The film provided on the core member prevents the sealing member from thermally adhering to the sealing portion and from thermally deteriorating.

Plating apparatus and plating method that can plate more uniformly on a processing surface of a workpiece are provided. The plating apparatus is comprised of a plating solution bathe which is provided with a first electrode held in a state soaked in a plating solution; a workpiece holding mechanism which holds a workpiece to contact its processing surface to the plating solution; and a contact member, disposed in the workpiece holding mechanism, that electrically contacts with the circumferential edge of the workpiece so to form a conductive layer on the workpiece surface as a second electrode. The contact member is divided along the circumferential direction of the workpiece with which they are electrically contacted. Thus, even if the contact resistance between each section of the contact member with the workpiece is variable, it is possible to adjust the plating electric current for each section of the contact member.

摘要:
A heat treating device including a pressure detecting unit for outputting an output signal when a pressure in a heat processing furnace becomes a set value, an air release pipe having a first valve and a check valve, a differential pressure gauge shut off by a second valve in terms of pressure from the interior of the heat processing furnace, and an air feed pipe having a third valve. One ends of each of the air release pipe and the air feed pipe is connected respectively to the heat processing furnace and the other ends opened in air. In such arrangement, after processing gases are evacuated from the heat processing furnace, an inert gas is fed. Then when an internal pressure of the furnace becomes near an air pressure, the first valve is opened in response to the output signal of the pressure detecting unit to make the internal pressure of the heat processing furnace a little higher than the air pressure. When a differential pressure value of the differential pressure gauge is below a set value, the third value is opened to communicate the interior of the heat processing furnace with air through the air feed pipe. Then the cap closing the opening of the heat processing furnace is opened.
