A waterproof connector has a housing (2) for accommodating terminal fittings (1) connected to ends of wires (W). An engaging portion (28) is formed on the outer surface of the housing (2). A one-piece rubber plug (15) is mounted in a rear part of the housing (2) to collectively seal the wires (W). A holder (20) is fit to the rear part of the housing (2) to retain the one-piece rubber plug (15) and a cover (27) is arranged on a rear part of the holder (20). The holder (20) is formed with an opening (46) for exposing the engaging portion (28) if the holder (20) is mounted properly on the housing (2) and the cover (27) is formed with a lock (57) that can engage the exposed engaging portion (28).

A controller existing on a level above a media drive issues a first read command specifying a plurality of data blocks to the media drive, and upon detecting a time-out for the first read command, generates a second read command specifying a portion of the data blocks among the plurality of data blocks, and issues the second read command to the media drive. Upon receiving the portion of data blocks without detecting a time-out for the second read command, the controller reads the plurality of data blocks specified by the first read command by issuing the second read command to the media drive one or more times.

The storage control device and storage device error control method of the present invention prevent incorrect data from being read out to the host in advance, and thus improve the reliability. For example, the controller 5 that controls the disk array subsystem disperses and stores data on respective disks 1 through 3, calculates parity data, and stores this parity data on a disk 4. In cases where the updating of a certain block (D12) fails, so that data is not written into this block, this is an uncorrectable error. The data of this block (D12) is recovered on the basis of data and parity data stored on the other disks. The controller 5 also recovers data for another block (D13) following the block (D12) on the basis of other associated data and parity data. As a result, even if by some chance the block (D13) which has not suffered an uncorrectable error stores old data, the correct data can be recreated and provided to the host 7.

A lever (30) can be assembled in either of two postures symmetrical with respect to an axis of symmetry (19), and the rotating direction of the lever (30) changes depending on the assembling posture. Thus, the rotating direction of the lever (30) can be selected depending on circumstances. A cam follower (52) can enter a cam groove (33) regardless of the posture in which the lever (30) is assembled. The lever (30) can be held at a standby position by a holder (21L, 21R, 22, 34, 36), and the lever (30) can be locked at a connection position by a lock (21L, 21R, 23L, 23R, 39, 41).

Deep drawing of a work can be made by securing a certain amount of feed of the work from the side of a cushion ring to a vertical wall surface of a stationary die. In this drawing method, for the drawing of the work, a die part interlocked to a movable die is engaged in a recess of the stationary die in a direction different from the direction of pushing. An edge of the work is displaced in unison with the cushion ring and the movable die clamping it in cooperation, and the die part starts to push the work immediately before the instant when the work located in the vicinity of the cushion ring is brought into contact with the edge of the recess of the stationary die. The resistance of contact between the work and the stationary die thus is not increased in the vicinity of the cushion ring when the die part pushes the work, and a certain amount of feed of the work from the side of the cushion ring can be secured.

In combustion of gasified fuel by gasifying a low quality fuel and combusting the gasified fuel in a combustor, combustion of gasified fuel is controlled by sampling the gasified fuel at a constant flow rate at the upstream side of the combustor, combusting the sampled gasified fuel, detecting an overall energy level of sensible heat and heating value possessed per unit weight of the gasified fuel on the basis of the combustion temperature of the sampled gasified fuel, and controlling the flow rate of gasified fuel to be led to the combustor in accordance with a fluctuation in the detected overall energy level. Unstable combustion due to a fluctuation in the heating value of the gasified fuel and blow-out due to deficiency of the heating value can be prevented.

A gas turbine combustor comprising a combustor inner-pipe for forming a head combustion chamber and a rear combustion chamber having a diameter larger than a diameter of head combustion chamber. A combustor outer-pipe covers the combustor inner-pipe, and a fuel nozzle is disposed at an end part of the head combustion chamber for supplying fuel to said combustor inner pipe. A first group of ports are arranged for swirling and feeding air in an axial direction of the combustor inner-pipe. The first group of ports are around the fuel nozzle. A second group of ports for swirling and feeding air in a radial direction of said combustor inner-pipe are disposed in a side wall of the head combustion chamber near the fuel nozzle. A third group of ports for swirling and feeding air in a radial direction of the combustion inner-pipe and a fourth group of ports for feeding air in a radial direction of the combustor inner-pipe are provided and ar both disposed in a side wall of the head combustion chamber near the said rear combustion chamber. A fifth group of ports are disposed in a side wall of the rear combustion chamber near the head combustion chamber and a sixth group of ports are disposed in a side wall of the rear combustion chamber on a downstream side of the fifth group of ports. Another group of ports for swirling and feeding air into the head combustion chamber are disposed in a vicinity of a central portion of an end part of the head combustion chamber along an inner periphery of the fuel nozzle, with this group of ports and the first group of ports being constructed so that air flowing from both groups of ports has the same swirling direction.
摘要:
A combustor of a gas turbine having a plurality of liners defining combustion chambers, and transition pieces adapted to rectify the flow of the combustion gas discharged from the liners before the combustion gas is introduced to the turbine. A guide plate is disposed in the gap between each pair of adjacent transition pieces near the gas outlets of the latter so as to guide the flow of air to the radially outer surfaces of adjacent transition pieces, thereby to improve the cooling of these surfaces and, at the same time, to mechanically connect the adjacent transition pieces to suppress the vibration of the transition pieces.

A combustor for gas turbines includes a stepped cylindrical tube defining first, second and main combustion spaces. Primary air supply openings are formed in the tube portion defining the first combustion space, secondary air supply openings in the tube portion defining the second combustion space, and diluting air supply openings in the tube portion defining the main combustion space. To achieve effective cooling of the combustion gas within the combustion chamber, particularly in the second combustion space, and especially in the central portion thereof, and at the same time to maintain a stable combustion, the tube is formed so, and the cross-sectional areas of the primary, secondary and diluting air supply openings are dimensioned so, that 25 to 32% of the total amount of air supplied to the combustion chamber are used as primary air in the first combustion space, 38 to 50% as secondary air in the second combustion space, and less than 30% as diluting air in the main combustion space.
