Abstract: A vehicle air-conditioning device is provided which is capable of eliminating or suppressing vibration and noise generated due to the application of a counterpressure to an opening/closing valve. The vehicle air-conditioning device includes a refrigerant circuit R having a compressor 2, a radiator 4 to perform heat exchange between a refrigerant and air, an outdoor heat exchanger 7, a heat absorber 9, and a solenoid valve 40. The compressor 2 and the solenoid valve 40 are controlled to air-condition a vehicle interior. A decompression speed at a refrigerant inflow side of the solenoid valve when the compressor 2 is stopped and the solenoid valve 40 is closed is faster than that at a refrigerant outflow side thereof. When operation is stopped from a state in which the compressor 2 is operating with the solenoid valve 40 being in an opened state, the opened state of the solenoid valve 40 is maintained even after the compressor 2 is stopped.

Abstract: Embodiments of the present invention help to increase the capacity and the reliability of a disk drive device to improve the manufacturing yield thereof. An embodiment of the present invention sets a data track pitch for each head slider (recording surface) in accordance with head characteristics. This method for specifying the data track pitch is based on the distance between erase band ends (EBEs) of the both adjacent data tracks. The erase band of a data track is a band defined as the area where the already written data are erased in writing the data track. The distance between the erase band ends of the both adjacent data tracks corresponds to the width SW of the area which is not erased by the adjacent data tracks. Specifying the data track pitch based on this leads to increase in the data capacity of each recording surface and secure prevention of occurrence of a squeeze error.

Abstract: Embodiments of the present invention help to improve test processes for hard disk drives (HDDs) and increase the manufacturing efficiency of HDDs. According to one embodiment, a test process performs a test on an HDD with respect to a plurality of items and stores one or a plurality of test results. Moreover, it determines the optimum specification category to which the HDD is to belong based on the stored test results. One factor of the specifications—storage capacity—has been determined before the test process or is determined during the test process. The test process classifies HDDs with the same storage capacity into different specification categories, and this classification may be performed in a single test process. This achieves efficient manufacture of HDDs with different specifications corresponding to the diversified usage of HDDs.

Abstract: A compressor used in a refrigerating cycle is provided as a miniaturized and lightweight unit at low production cost by selecting an optimal material to constitute components or by forming the housing in a specific shape so as to allow the components to have smaller wall thicknesses while assuring sufficient strength. A tough material achieving a tensile strength greater than 800 N/mm2 is used when forming at least one of the components constituting the housing and the internal mechanisms. In addition, over the area of the housing where the bottom surface and the inner circumferential surface connect with each other, the bottom surface forms an R-shaped portion and the inner circumferential surface forms a sloping portion or an R-shaped portion.

The gasket (10) includes a raised portion (35) rising so as to surround a sealed portion. An end (43) of the raised portion (37) and a base surface (30) of the gasket (10) are not positioned on a single plane. In addition, the raised portion (35) is constituted with a flat surface (40) set at a height different from the height of the base surface (30) and an inclined surface (41) with a predetermined angle of inclination connecting the flat surface (40) with the base surface (30).
