摘要： In carrying out a cast-in process, a cast-in insert member is placed into a cast forming cavity in a casting mold, and a casting is conducted. The cast-in insert member has a barrier layer on its non-deposited surface for inhibiting the deposition of a molten metal. During casting, a portion of a molten metal is introduced to a heating chamber on the side of the barrier layer to come into contact with the barrier layer. Thus, the cast-in insert member can be heated not only from the side of its deposited surface, but also from the side of its non-deposited surface, thereby providing an enhanced strength of deposition of the cast-in insert member.

摘要： A non-circular cross-section coil spring, wherein a spring wire having a non-circular cross-section shape is coiled into such configuration that a major diameter of the cross-section is directed in the direction intersecting with a center line of the spring. Torsion is preliminarily given to at least a part of the spring wire so that the coil spring inner circumferential surface side of the above-mentioned major diameter may be deviated to a free end side of the spring with reference to the reference plane of extension and contraction of the coil spring in the case where the coil spring is a compression coil spring, but to the side of the aforementioned reference plane of extension and contraction in the case where the coil spring is a tension coil spring. In a coil spring comprising a larger pitch portion and a smaller pitch portion, a large angle of torsion is preliminarily given to the larger pitch portion and a small angle of torsion is preliminarily given to the smaller pitch portion. Upon application of a load, an angle of torsion of the spring wire becomes zero or nearly zero, thereby increase of the maximum shearing stress generated at the inner circumference of the coil spring can be suppressed, and also sharing stress in the spring wire can be made uniform.

摘要： A drive cam follower operatively connected to an engine valve and a free cam follower capable of becoming free relative to the engine valve are adjacently disposed and adapted to impart in mutually different modes of operation in response to said engine valve rotation of a cam shaft. A connection change-over mechanism is provided between the cam followers and is capable of changing-over the interconnection and disconnection thereof, and resilient biasing means is provided between the free cam follower and the engine body for resiliently urging the free cam follower toward the cam shaft. The resilient biasing means comprises an urging piston slidably received in the engine body for abutment against the free cam follower, and a spring arrangement interposed between the urging piston and the engine body to resiliently bias the urging piston in a direction to abut against the free cam follower. The spring arrangement may comprise series-related springs having different spring constant with one of the springs having a non-linear load characteristic. A vent opening and a lubrication arrangement are provided to facilitate operation of the piston. The urging piston is provided, at its end closer to the free cam follower, with an abutment formed with a smaller diameter to abut against the free cam follower. This facilitates assembly of the resilient biasing means to the engine body, and makes it possible to dispose the resilient biasing means in proximity to a pivoting point of the free cam follower.

摘要： In a system for adjusting the tension of an endless transmitting belt in an internal combustion engine, a control system automatically adjusts the tension to be applied from a tensioner to the endless transmitting belt. The control system includes a driving-side rotational state detecting device for detecting the rotational state of a driving wheel which drives the endless transmitting belt. A driven-side rotational state detecting device detects the rotational state of a driven wheel driven by the endless transmitting belt. A control unit calculates a difference in rotational phase between the driving and driven wheels from results of detection by both rotational state detecting devices and controls the operation of a tension changing device in accordance with the difference in rotational phase. Thus, it is possible to accurately and quickly accommodate a very small variation in tension of the transmitting belt without specially using a strain gauge.

摘要： In a toothed sintered pulley comprising a rim having a large number of teeth on its outer peripheral surface and lightening grooves at those portions of its inner peripheral surface which correspond to the individual teeth, a boss located radially inside of the rim, and a connection which connects the inner peripheral surface of the rim with an outer peripheral surface of the boss, the porosity of the rim is set larger than that of the boss. In addition, the connection is connected to axially intermediate portions of the inner peripheral surface of the rim, and lands are provided in a one-side half of the rim projecting from this connection in one of axial directions, so that each land is located between the two adjacent lightening grooves, with the radial thickness of the land being gradually increased from an outer end face of the one-side half toward the connection. This makes it possible to provide a toothed sintered pulley which is lightweight; in which any backlash noise due to meshing of the rim with a belt can be reduced, and the strength of the boss cannot be injured, and in which the rigidity of the one-side half in the rim is improved while suppressing the increase in weight thereof to the utmost.

摘要： An improved process for producing a laminated resin foam composed of two resin foam layers of different characteristic properties wherein the layers are integrally bonded together. A first foamable resin liquid for forming flexible foam is poured into a first space in a foam processing mold on one side of a barrier projecting from the wall of the mold and pouring a second foamable resin liquid for forming a foam less flexible than the first flexible foam into a second space in said foam processing mold on the other side of said barrier. The two foamable resin liquids foam beyond the barrier into contact with each other to form the two laminated foam layers. One improvement in the process includes wetting a substantial portion of the mold cavity with the first foamable resin liquid. Various shapes of molds and barriers will produce different shapes and characteristics of the resultant foam pad, such as for a car seat.
