Abstract: In a multicylindrical rotary compressor constituted to be usable by urging an only first vane with respect to a first roller by means of a spring member to switch a first operation mode in which first and second rotary compression elements perform compression works and a second operation mode in which substantially the only first rotary compression element performs the compression work, an object is to reduce generation of collision noises due to collision of the second vane with the second roller at a time when the first operation mode is switched to the second operation mode, and a pressure in a back-pressure chamber of the second vane is discharged on a low-pressure chamber side in a second cylinder in a case where the first operation mode is switched to the second operation mode.

Abstract: A compressor includes two rotary compressing elements in a vessel. One of the compressing elements operates while the other element is in a non-operating mode. In the non-operating mode, inflow of refrigerant gas into the cylinder of the rotary compressing element is blocked and a suction side pressure of the rotary compressing element is applied as a back pressure to a vane. A compressing system includes the compressor and a controller and operates in first and second operation modes. In the first operation mode, refrigerant gas flows into a cylinder and an intermediate pressure, a result of flow of the refrigerant gas from between a vane and a guide groove into a back pressure portion, between a suction side pressure and a discharge side pressure, is applied as a back pressure to bias the vane against a roller.

Abstract: An object is to avoid generation of a collision sound of a second vane of a compression system comprising a multicylinder rotary compressor being configured to be used by switching of a first operation mode in which both rotary compression elements perform a compression work and a the second operation mode in which the only first rotary compression element substantially performs the compression work. When the second operation mode is switched to the first operation mode, discharge-side pressures of both the rotary compression elements are applied as a back pressure of the second vane, and thereafter an intermediate pressure is applied which is between suction-side and discharge-side pressures of both the rotary compression elements. When the first operation mode is switched to the second operation mode, a valve device interrupts flowing of a refrigerant into a second cylinder, and thereafter suction-side pressures of both the rotary compression elements are applied as the back pressure of the second vane.

Abstract: A silica-based interlayer insulating layer having a low dielectric constant is formed with SOG material on a substrate, in which a wiring-layer forming space is then formed. If necessary, a UV ray irradiation is performed under an oxidizing atmosphere. A Si—OH bond is formed on a surface of the insulating layer. A monomolecular layer film is then adhered to the inner surface of the space, which is then modified to be a catalyst with a solution containing Pd compound. On the catalyst monomolecular layer, a copper-diffusion-resistant film is formed by electroless plating, on which a copper plate is then formed as a wiring layer.
