Abstract: In a vane pump disposed inside a transmission case of a continuously variable transmission, a pump case (20), a pump drive shaft (8) rotatably supported by a shaft bore (9) of the pump case (20) to rotate a rotor (5), and a drain port (17), one end thereof being opened to a shaft bore (9) of the pump drive shaft (8) and the other end being opened to an outside of the pump case (20) are provided. A leaked oil flown via the drain port (17) from a pump discharge side is discharged to an outside of the pump case (20).

Abstract: The exhaust pipe includes a front section, a rear section, and a midway section. The front section and the rear section extend along a fore-and-aft direction of the vehicle. The midway section is located between the front section and the rear section. The midway section extends in a lateral direction of the vehicle. Further, the midway section has at least one bent portion, which is bent to have a corner oriented forward or rearward of the vehicle. As a result, stress applied to the exhaust pipe is reduced.

Abstract: A body bore 2 formed in a body 1 is closed with a cover 9, as well as a cam ring 4 is incorporated into the body bore 2, and a rotor 6 is arranged inside the cam ring 4. Vanes 7 move in and out along an inner surface of the cam ring 4 with rotation of the rotor 6. An iron reinforcing plate 8 is interposed inside the body bore 2 between the cam ring 4 and the cover 9.

Abstract: A spool bore (4) where a spool (6) slides, a concave portion (23) opened to the spool bore (4) and facing a return port 12 opened to the spool bore (4), and a land portion (11) disposed in an outer periphery of the spool (6) are provided. A width of the concave portion (23) and a width of the return port (12) each are greater than a width of the land portion (11) and a groove bottom (23a) of the concave portion (23) is formed to be a flat plane generally in proportion to an axis line of the spool (6).

Abstract: A phosphazene composition which has a content of volatile components of not less than 0.02% by weight and not more than 1.0% by weight when it is heated at 200° C. for 2 hours; is excellent in resistance to hydrolysis, and when the phosphazene composition is added to a resin, there is provided a resin composition which highly maintains the balance of resistance to hydrolysis, flame retardancy and stability of electric characteristics in a high-frequency field of not less than 1 GHz.

Abstract: A sewing system including a stitch-forming device including at least one sewing needle, for forming stitches on at least one workpiece; a feeding device which feeds at least one of the stitch-forming device and the workpiece relative to the other of the stitch-forming device and the workpiece along a reference plane; a control device which controls, according to at least one set of sewing data corresponding to at least one sewing pattern including a plurality of stitches, the stitch-forming device and the feeding device to form the stitches of the sewing pattern on the workpiece; a dimension-data memory which stores a plurality of sets of dimension data which correspond to a plurality of dimensions, respectively, each of which relates to the set of sewing data; and a selecting device which is operable for selecting one of the sets of dimension data stored in the dimension-data memory.

Abstract: A sewing machine including a needle bar to which a sewing needle conveying a sewing thread is secured, a main shaft to which the needle bar is connected, a loop catcher which cooperates with the sewing needle to catch a loop of the sewing thread conveyed by the needle, a catcher shaft to which the loop catcher is connected, a drive motor which drives at least one of the needle bar and the loop catcher by rotating a corresponding one of the main shaft and the catcher shaft, a first sensor which detects a first reference rotation position of at least one of the main shaft and the catcher shaft and generates a first detection signal indicating that the one shaft is taking the first reference rotation position, a second sensor which detects a second reference rotation position of the drive motor and generates a second detection signal indicating that the drive motor is taking the second reference rotation position, and an indicating device which indicates, based on the first detection signal, that the one of the

Abstract: An apparatus for measuring a remaining amount of a bobbin thread wound on a bobbin accommodated in a shuttle of a sewing machine, including a measurement bar displaceable along a displacement path from outside the shuttle toward an axis line of the bobbin inside the shuttle, a driver which displaces the measurement bar along the displacement path so that a free end of the bar contacts the outer surface of a roll of bobbin thread wound on the bobbin, a sensor which detects the displacement of the measurement bar and generates a displacement signal representative of continuous change in displacement amount of the bar, a signal-characteristic determining and storing device which determines a characteristic of the displacement signal based on respective values of the displacement signal when the measurement bar is located at a plurality of reference positions on the displacement path, and stores data indicative of the determined signal characteristic, and a remaining-amount determining device which determines the

Abstract: An apparatus for measuring a remaining amount of a bobbin thread which is wound around a bobbin accommodated in a shuttle of a sewing machine, including a measurement bar which is displaceable along a displacement path from outside the shuttle toward an axis line of the bobbin inside the shuttle, a measurement-bar driver which displaces the measurement bar along the displacement path so that a free end of the measurement bar contacts an outer surface of a roll of the bobbin thread remaining on the bobbin, a displacement-speed control device which controls the measurement-bar driver to displace the measurement bar such that the free end of the measurement bar contacts the outer surface of the roll of the bobbin thread at a speed lower than a highest speed of the displacement of the bar along the displacement path, and a remaining-amount determining device which determines the remaining amount of the bobbin thread on the bobbin, based on an amount of the displacement of the measurement bar along the displacemen

Abstract: A sewing system includes a plurality of sewing machines and a managing apparatus for managing sewing operations of the sewing machines. The managing apparatus determines a type of a work to be sewn by each of the sewing machines and sewing steps for such work, and supplies an identification code thereof to the sewing machines. A controller of the sewing machine reads out sewing data corresponding to the identification code from sewing data storage, and controls the sewing machine in accordance with the sewing data.
