A back-pressure valve comprising a case through which oil passes and in the interior of which a first oil chamber and a second oil chamber are defined, a piston slidably accommodated within the case so as to partition the first oil chamber and the second oil chamber, a spring and a spring which urge the piston in a sliding direction thereof, and a projecting member and a check valve which allow the first oil chamber to communicate with the second oil chamber when the pressure of the oil in the first fluid chamber reaches a predetermined pressure, wherein an area of the piston on which oil pressure is received in the first oil chamber is made lager than an area thereof on which oil pressure is received in the second oil chamber, and wherein part of the piston which is located at an end thereof which is opposite to the other end thereof which faces the first oil chamber is made to communicate with the outside of the case.

A flight control surface control unit controls a swinging angle of a flight control surface of an aircraft by providing a swinging force to the flight control surface and swinging the flight control surface about a pivot. The flight control surface control unit comprises an actuator mounted on an airframe of the aircraft with a final output shaft of the actuator positioned coaxially with the pivot of the flight control surface. The final output shaft of the actuator and the flight control surface are connected to each other. The flight control surface is formed with a recess in the vicinity of the pivot thereof and the actuator is accommodated in the recess.

A back-pressure valve comprises a case having first and second oil chambers through which oil passes. A piston is slidably accommodated within the case to partition the first oil chamber and the second oil chamber. A spring urges the piston in a sliding direction. A projecting member and a check valve allow the first oil chamber to communicate with the second oil chamber when the pressure of the oil in the first fluid chamber reaches a predetermined pressure. An area of the piston on which oil pressure is received in the first oil chamber is made lager than an area on which oil pressure is received in the second oil chamber. A part of the piston located at an end thereof opposite to the end thereof which faces the first oil chamber communicates with the outside of the case.

An actuator monitoring circuit 1 which is mounted in an airplane and monitors an actuator 30 having a piston (output portion) calculates the moving distance of the piston, and outputs, when the moving distance exceeds a predetermined threshold, an approaching notification signal 78s and a progression notification signal 79s to notify the excess over the threshold.

A conveying device has: a moving member provided so as to be movable; a rotating member rotatably supported at the moving member; and a holding member rotatably supported at the rotating member, and able to hold a sheet. In a state in which the holding member is holding the sheet, the holding member conveys the sheet by at least one of movement of the moving member, rotation of the rotating member with respect to the moving member, and rotation of the holding member with respect to the rotating member.

A conveying device for a printing plate precursor which takes the printing plate precursor and an interleaf sheet out from a cassette, and which, along a conveying path to an exposure section, takes-off only the interleaf sheet. When a leading end of the interleaf sheet passes by an interleaf sheet peeling roller disposed on the conveying path, the interleaf sheet peeling roller rotates in a direction opposite to a direction of conveying to the exposure section, and contacts the interleaf sheet, and slack is formed in the interleaf sheet between the interleaf sheet peeling roller and a conveying roller. A slack portion is nipped between two belts and fed to a forked-off path, and the interleaf sheet is removed from the conveying path. It is possible to feed only the printing plate precursor out to the exposure section while continuing to convey the printing plate precursor.

A brake drum includes a ring-shaped drum body, and a friction member secured to the inner circumferential surface of the drum body. Because the drum body is formed of a lightweight Al alloy and the friction member is formed of an Al-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projection portions formed on its outer periphery, is cast enveloped by molten metal of the Al alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.

A sheet feeder for use with a stack having plates and sheets alternating. Sheets are removed by being reliably suction adhered with a sucker. The sheet feeder includes a suction device, and the sucker and device are mounted at a supporting portion. In order to allow suction adhering of the plates and sheets alternately stacked in a magazine, the suction device is operated when the sucker is brought into contact with the sheet, and the sheet is raised separately from the plate. Thereafter, the sheet is suction adhered to the sucker by suction. This makes it possible to prevent the sucker from suction adhering to the plate together with the sheet, and only the sheet is reliably removed from the stack.

An information processor includes an immediate data latch and a pair of multiplexers in an input portion of an adder in a data address generator. The structure controls operation of the multiplexer in accordance with a register conflict detecting control signal and eliminates an idle state of a pipeline by detecting a register conflict between a register for holding immediate data, indicated by a precedent instruction instructing a specific register to store the immediate data, and a register used for calculation of memory addresses to be used for execution of a succeeding load/store instruction. The immediate data latch directly latches an immediate data indicated by the precedent instruction and outputted by an instruction decoding portion. Then, if the register conflict detecting portion detects the register conflict, the immediate data latched by the immediate data latch is used for calculation of memory addresses. This control operation is performed by changing the multiplexer according to the register conflict control signal to input the data from the immediate data latch to the adder.
