摘要:
According to the embodiments, a core block is formed on a semiconductor chip, and is constructed of an integrated circuit that can operate independently. A power-supply switch is formed on the semiconductor chip, and connects or disconnects the core block to or from a power line. A capacitor is formed on the semiconductor chip, and is connected to the power line in parallel to the core block. A selection switch is formed on the semiconductor chip, and connects or disconnects the capacitor to or from the power line.
摘要:
A fluid compressor comprising a helical blade type compression mechanism that includes a cylinder, a roller arranged inside the cylinder and a helical blade interposed between the roller and the cylinder. The blade, the roller and the cylinder are formed of materials whose coefficients of thermal expansion satisfy relationships: Blade>Roller>Cylinder. According to this invention, pressure release can be easily performed in the case where the liquid flows back or under a low-temperature condition as at the time of actuation. In addition, the compression performance can be improved under a high-temperature condition during operation.
