Abstract: One point on a surface of a qualified article is measured in advance by a color sensor without contact, and a qualification reference value is set based on an output value thereof. Thereafter, one point on a surface of an inspection target of same design specifications as the qualified article is measured by the color sensor without contact, and an output value thereof is compared with the qualification reference value, and qualification/failure is judged. Because qualification/failure can be carried out without contacting an inspection target in this way, application to a high-speed production line is possible.

Abstract: The purpose of the present invention is to provide a shot peening apparatus for which size increase is limited by projecting a shot material evenly on a workpiece using a single projector. The present invention provides a shot peening apparatus equipped with a workpiece-conveying mechanism for conveying a workpiece and a projector for projecting a shot material at the workpiece. The workpiece-conveying mechanism is equipped with: a pair of rollers, which extend in the workpiece conveyance direction, on which the workpieces are loaded, and which are rotated centered on the longitudinal axis line; an endless chain; and conveyance members for pressing and conveying workpieces in the conveyance direction.

Abstract: The purpose of the present invention is to provide a drum-type shot peening device capable of shortening processing time. This shot peening device comprises: a bottomed, cylindrical drum having one end thereof open; and a projector provided on the open side of the drum and which projects projection material on to a workpiece inserted inside the drum.

Abstract: A stroke sensor detects a distance between a first member and a second member provided movably toward and away from the first member. The stroke sensor includes a magnetism generator provided in the first member and configured to generate magnetism, a magnetic body provided in the second member and configured to be biased toward the magnetism generator by a magnetic force generated from the magnetism generator, and a pressure detector provided in the second member, held in contact with the magnetic body biased by the magnetic force from the magnetism generator and configured to detect the distance between the first and second members on the basis of a change of a pressure acting from the magnetic body.

Abstract: In an internal combustion engine having a pair of balancer shafts (53, 54), an engine torque is transmitted from a crank gear (28) to an oil pump gear (74) on a drive shaft (73) of an oil pump (71) via a first idler gear (84) and the first balancer shaft gear (64). The engine torque is also transmitted to a fuel pump (72) from the crank gear to a fuel pump gear (78) via the first idler gear and a second idler gear (86), and to the second balancer shaft gear (67) via the first idler gear and second idler gear. Alternatively, the engine torque may be transmitted to the fuel pump from the crank gear to the fuel pump gear via the first idler gear, second balancer shaft gear and second idler gear. As the oil pump gear is actuated by the crank gear via the first idler gear, the oil pump gear is not subjected to the loading caused by the balancer shaft, and hence can be made of a compact and light-weight gear.

Abstract: Data packets [P(1) to P(8)] transmitted from a root station (1) is received at a plurality of leaf stations (A to C). The data packets [P(1) to P(8)] include a data block [B(101)], etc. each having an error correcting code. Besides, the data packets [P(1) to P(8)] includes information [L(201), L(202) to L(801), L(802)] on the right to make a retransmission request, for giving the right to make a retransmission request to the two of the leaf stations (A to C) in one communication cycle. The leaf stations (A to C) request the root station (1) to retransmit a data block for which error correction is impossible in a communication cycle when the leaf stations (A to C) are respectively given the right to make a retransmission request, by transmitting retransmission requesting packets [LA(1), LB(1), LC(1)], etc. The root station (1) transmits a data packet including the required data block in and after the next communication cycle.
