The housing mounting portion (61) includes a flat plate (63) near the circuit board (90), a flat plate (64) distant from the circuit board (90) and a bent portion (65) between the respective flat plates (63, 64) and bulging in a plate thickness direction with respect to the flat plates (63, 64). The bent portion (65) is provided over an entire width of the housing mounting portion (61) in a plate width direction between the flat plates (63, 64).

Abstract: A connector includes a housing (10) formed with a terminal accommodation chamber (13) and a terminal fitting (30) to be inserted into the terminal accommodation chamber (13) from behind the housing (10). A stabilizer (35) projects from an outer peripheral surface of the terminal fitting (30), and an interfering portion (19) is formed on an inner wall of the terminal accommodation chamber (13). The terminal fitting (30) contacts the interfering portion (19) when the terminal fitting (30) is inserted into the terminal accommodation chamber (13) in an improper posture, and this contact presses the terminal fitting 30 in a direction intersecting a projecting direction of the stabilizer (35).

Abstract: A housing (10) includes a lock arm (31) for resiliently connecting and holding a mating housing (90). A detector (60) is movable to a standby position and a detection position with respect to the lock arm (31), and includes a resilient arm (62) to be resiliently locked by the lock arm (31) at the standby position. The lock arm (31) includes colliding portions (43) arranged at both sides of a front part of the resilient arm (62) and projecting farther forward than a front end of the resilient arm (62) and configured to contact a wall surface of the housing (10) or the mating housing (90) by a resilient returning movement of the lock arm (31) when the detector (60) is at the detection position.

Abstract: A connector includes a housing (10) formed with a terminal accommodating portion (11), terminal fittings (15) to be inserted into the terminal accommodating portion (11) from behind, a front retainer (30) to be assembled with the housing (10) from front, and locking surfaces (29) formed in the terminal accommodating portion (11) and configured to hold the front retainer (30) and the housing (10) in an assembled state by having locking projections (37) of the front retainer (30) locked thereto from behind. The locking surfaces (29) are inclined with respect to an assembling direction of the front retainer 30 with the housing (10).

Abstract: Disclosed is a file management method for a file system that has a storage device to save data blocks and a main memory of computer, the storage device and the main memory being provided with a management block to save in-use information, in-transition information, and information about expansion to an adjacent data block. The method has the steps of: checking the in-use information of the management block on the main memory when securing a second data block so as to store data relating to a first data block; initializing a management area of the second data block; storing the position of the first data block into the management area of the second data block; storing the position of the second data block into a management area of the first data block; copying the information of the management block on the main memory to the management block on the storage device; and removing the in-transition information.

Abstract: A buffer cache apparatus includes a storage unit storing data, a buffer cache and a control unit. The buffer cache stores a balanced tree and free lists. Data containing buffers are hierarchically provided as nodes in the balanced tree, and the free lists are respectively provided for different sizes. Each of the free lists includes at least one free buffer when the at least one free buffer exists. The control unit is responsive to a data request. The control unit searches the free lists for a desired buffer based on a size of a requested data requested by the data request, when the requested data does not exist in the balanced tree. Also, the control unit adds the desired buffer to the balanced tree to store the requested data from the storage unit into the desired buffer. The desired buffer has a size larger than the requested data size and as small as possible.
