    Abstract: A ski chair lift with variable speed drive for each chair. A linear motor is used in lieu of the conventional closed loop tow cable. The stator of the linear motor includes a closed loop I-beam guide rail, electromagnets secured to the top flange of the I-beam, and permanent magnets secured to chair lift carriers which are driven by selective energization of the electromagnets. Failsafe stops and brakes delimit movement of the chairs on the guide rail in the event of a power failure.

    Abstract: A silent chain using double-sided driving link plates having symmetrical upper and lower teeth has a problem that it is unable to assure a required risky sectional area of the plates because a width between upper and lower crotches is narrow. The invention provides a silent chain using double-sided driving link plates whose required risky sectional area is maintained by using link plate whose back side is undercut and whose upper and lower parts are unsymmetrical even though its front side has a shape of a normal link plate. A distance from a line connecting centers of pin holes to a bottom of an upper-side crotch is equal to or more than ½ of a diameter of the pin hole to assure the risky sectional area. Teeth of the back side are cut away to form a flat surface to assure a contact area with a shoe and others.

    Abstract: A bush is pressed into a link plate in a turning link rank that turns relatively with a pin. The bush is molded into a seamless cylindrical shape by cold-forging and is coated with a metal carbide layer formed by cementation of chrome, vanadium and other metals and having Vickers hardness of 1300 Hv or more similarly to the pin. Afterwards, the bush is treated by a quenching, tempering or isothermal transformation process. Thereby, wear resistance of the pins and the link plates of a silent (link) chain is improved, productivity is improved and associated costs are reduced.
