摘要： An information recording disc is provided with a magnetic attracting member in the form of metal piece or magnetic material which serves for attracting a disc member for recording, in particular, for optical recording and reproducing of information, to a spindle of a recording and reproducing apparatus. The magnetic attracting member is held in the space of a holder which is fixedly secured to the disc without the magnetic attracting member being fixedly secured to the disc. This arrangement enables a magnetic clamping of the disc member which provides for a decrease of retardation and is suitable for miniaturization of the apparatus.

摘要： A silent chain, as well as a rocker pin and a plate of the silent chain, are provided which are capable of enhancing the transmission efficiency, and improving the fatigue strength of the plate to thereby prolong the service life of the silent chain. Rocker pins are inserted into the pin holes of each plate of a plurality of plates of a silent chain. The rocker pins are located closer to outer ends of the plate and are formed with generally flat plate abutting surfaces. The plate abutting surfaces are received by generally flat pin seating surfaces of the pin holes, respectively, to surely prevent rotation of the rocker pins relative to the pin holes. Further, in addition to the generally flat pin seating surfaces, generally flat and short continuous surfaces are formed centrally up and down of each pin hole. Thus, stress concentration on the plate is diminished and the fatigue strength of the plate is improved.

摘要： In a method and apparatus for press bending a metal plate, a punch is inserted into a recess of a die to bend a plate. The punch has a first edge formed away from a die and a second edge formed near the die. A corner of the recess of the die opposed to the punch is chamfered. The chamfered face has a third edge formed at the border of the top side of the die at the chamfered recess. In a first half of the press bending, the plate is bent with the first and third edges serving as lines of contact. Subsequently, the plate is further bent with the second edge serving as a line of contact. A portion of the punch between the first and second edges is held in a non-contact state with the plate throughout steps of press bending the plate.

摘要： An improved friction drive chain especially for a continuously variable transmission has a plurality of friction plates, each of the friction plates being substantially I-shaped in lateral section. The friction plates are arranged adjacent one another and connected by connecting link elements received in recesses formed in both lateral sides of the friction plates between upper and lower beam members of said friction plates. The connecting link elements are laterally grooved to bear longitudinally against the friction plates. The outer surfaces of the lower beam members of the plates define friction drive surfaces for contact with driving and/or driven pulleys. The friction plates are heat treated to increase strength, for example by quenching and annealing. The friction drive surfaces are formed with hardened layers by surface hardening treatment such as by electron beam or laser.

摘要： The invention relates to apparatus and methods for manufacturing a bent product by press bending a malleable material. The bent product is bent along the lengthwise axis and has a bottom wall and at least one sidewall in cross section. The apparatus preferably includes a die having within its surface a recess. The recess is bent along the lengthwise axis. The apparatus also includes a punch that may be inserted into the recess of the die. The die and the punch substantially correspond to each other such that the die and the punch include a first portion having a first bend radius corresponding to a lengthwise bend in the bent product and a second portion having a second bend radius corresponding to a linear region of the bend product. If the first bend radius is smaller than the second bend radius, chamfered faces formed in the die and punch are shallower and narrower in the first bend radius than the second bend radius. This relationship permits the folding of the material within the lengthwise bend region to be completed before the folding of the material by the die and punch regions having the larger bend radius.

摘要： In a rocker pin type friction transmission chain, the engaged surfaces of the rocker pins and pin insertion holes in the link plates are in the form of parts of an ellipse which are symmetrical with respect to the minor axis of the ellipse. This configuration is easy to machine, prevents relative rotation of the pins and the link plates, avoids cracking of the link plates due to concentrations of loads, and reduces the likelihood of fatigue failure due to excessive pressures exerted by the pins and link plates on each other.

摘要： A rocker-pin type continuously variable transmission chain having a plurality of link plates connected endlessly by rocker pins which project into pin insertion holes formed in the link plates. Each pin insertion hole defines thereon a side load transmitting surface which engages an opposed side load transmitting surface on the rocker pin. These load transmitting surfaces on the rocker pin and hole have opposed center surface portions which are maintained free of contact with one another. A pair of concave surface portions are smoothly joined directly to opposite ends of the center surface portion of the hole, and project outwardly in opposite directions therefrom. A similar pair of convex surface portions are formed on the rocker pin, and are joined to opposite ends of the center surface portion thereof and project outwardly therefrom. The concave and convex surface portions are defined generally as partial elliptic surfaces which are generated about and symmetrically disposed with respect to a major axis of an ellipse, which major axis extend centrally of the bore in the lengthwise or longitudinal direction of the link plate. The elliptically shaped concave and convex surfaces directly engagingly contact one another, and create a wedge-like configuration which prevents rotation of the rocker pin relative to the bore, and provides for uniform load transmission over the extensive surface areas defined by the contacting convex and concave surface portions.
