In a device for supplying secondary air in a gas turbine engine provided with an inner shaft (8) and a hollow outer shaft (7) coaxially nested with each other, a seal air introduction passage (71, 85, 88) is defined inside the engine for introducing a part of high pressure air drawn from a high pressure compressor into a seal section provided in each of the bearing boxes for supporting the inner and outer shafts; and a swirl air cooling turbine (59) is provided in the seal air introduction passage and attached to a part attached to the outer shaft in a rotationally fast manner. The swirl air cooling turbine (59) is formed around a section of the outer shaft intermediate between the high pressure compressor and the high pressure turbine, the swirl air cooling turbine including a spiral flow path extending in a substantially cylindrical plane coaxial with the outer shaft. Because the high pressure swirl air is cooled by the swirl air cooling turbine provided in a radially central part, the energy of the swirl air is effectively expended, and this prevents the generation of a stagnation zone. Thereby, the secondary air can be favorably cooled before it is forwarded to the user such as the bearing boxes without causing an undue rise in the pressure of the impeller back chamber.

A printer having a hopper without shaft which performs a print operation on a roll of continuous paper. Detection marks are provided in flanges provided in supported members removably attached to the continuous paper, and the presence / absence of the detection mark in a detection position of an optical sensor is determined. A rear end of the continuous paper in the hopper is determined if the result of determination of the presence / absence of the detection mark during conveyance of the continuous paper is the same. A passage length from the position of the determined rear end of the continuous paper to a print unit is equal to or longer than a predetermined maximum print size. By this arrangement, the rear end of the continuous paper can be detected without upsizing the apparatus and without complicating the structure, and the continuous paper can be effectively utilized without causing shortage of the continuous paper during execution of print operation.

A variable toe angle control system for a vehicle that can be incorporated with a fail-safe mechanism. When a fault of the system is detected, at least one of toe-angle actuators is actuated to make toe angles of two wheels agree with each other. When one of the wheels has become fixed in position without regard to a control signal supplied to the corresponding actuator, the actuator for the other wheel is actuated so as to make the toe angles of the two wheels equal to each other. When at least one toe-angle sensor is found faulty, the actuators are both actuated until the actuators reach positions corresponding to stoppers. When information for determining target values of the toe angles of the right and left wheels is found faulty, the actuators are both actuated until the actuators reach positions corresponding to prescribed reference toe positions.

A light unit, a backlight, a front light, and a display device, have a structure such that an uneven luminance generated in display is suppressed by radiating light in a sufficient amount even to an end portion of a display region, thereby uniformly radiating light in a sufficient amount to the entire display region, without a complicated structure.

In a torsion beam wheel suspension system, a stabilizer bush made of resilient material is received in a hollow interior of a torsion beam that connect intermediate points of a pair of trailing arms, and retains an intermediate part of the stabilizer to the torsion beam. A bracket including a pair of vertical walls opposing lateral sides of the stabilizer bush is attached to a part of the torsion beam to prevent the lateral shifting of the stabilizer bush without any part of the bracket or stabilizer bush restraining the torsional deformation of the stabilizer or torsion beam. The vertical walls may be spaced apart from the stabilizer bush. The structure is not costly and does not cause any complication or difficulty in the assembly work of the rear wheel suspension system. The bracket may have dual purposes of retaining the stabilizer bush and supporting a dynamic damper.

A power supply coil is disposed on a rear surface of a display via a shield plate. When a current flows in the power supply coil, a magnetic flux emitted from the power supply coil traverses an opening of the shield plate. As a result, the power supply coil and the shield plate are electromagnetically coupled and the shield plate defines and functions as an antenna. Accordingly, a communication terminal communicates favorably with a smartcard, which is a device positioned on a front surface side of the display.
