A tire building apparatus includes a main hollow shaft, a rotatable screw shaft inserted in the main shaft, a pair of slider units axially movably supported so that upon rotating the screw shaft the slider units move through equal distances toward and away from each other, a pair of support member assemblies expansibly and contractibly supported by the slider units for supporting the bead portions of the green case on radially insides by the support member assemblies when expanded to increase their diameters, a pair of movable blocks axially movably supported to be able to abut against the slider units, a drum core in the form of a ring to surround the main shaft between the slider units, a link mechanism connecting the drum core and the movable blocks for expanding the drum core when the movable blocks move axially inwardly toward each other and contracting the drum core when the movable blocks move axially outwardly away from each other, a pair of stoppers for limiting axially outward movement of the movable blocks when the drum core contracts to its minimum diameter, and a spring for urging the movable blocks axially outwardly.

The invention provides a heat insulating glass plate with a multilayer coating which is fairly low in transmittance for solar radiation and fairly high in transmittance for the visible light and also for radio waves. The multilayer coating is a lamination of transparent and dielectric layers and has three essential layers in which the middle layer is higher or lower in refractivity than the inner and outer layers. The coating may have five layers in which the second and fourth layers are higher or lower in refractivity than the remaining three layers. Each layer of the multilayer coating is a metal compound film deposited by sputtering or CVD. In a first embodiment of the three-layer coating each of the inner and outer layers is formed of SnO.sub.x, ZrO.sub.x, TaO.sub.x or AlN.sub.x having a refractive index of 1.8-2.1 and the middle layer is formed of TiO.sub.x having a refractive index of 2.2-2.5. In a second embodiment, each of the inner and outer layers is formed of SnO.sub.x, TiO.sub.x, ZrO.sub.x, TaO.sub.x, ZnO.sub.x, AlN.sub.x or SiN.sub.x having a refractive index of 1.8-2.5 and the middle layer is formed of SiO.sub.x, AlO.sub.x or Si.AlO.sub.x having a refractive index of 1.4-1.7. The heat insulating glass plates are useful as vehicle window glasses, and the second embodiment of the multilayer coating is very suitable for use in laminated glass.

A levitation, propulsion and guidance mechanism for an inductive repulsion-type magnetically levitated railway in which a vehicle runs along a track bed has superconducting coils fixedly arranged vertically on both sides of the truck of the vehicle at predetermined intervals therealong in a direction of travel of the vehicle. Propulsion coils are arranged on opposed walls of the track bed at predetermined intervals therealong in the direction of travel of said vehicle, and a propulsion power supply is connected to the propulsion conductor coils. Levitation-guidance conductor coils, each comprising upper and lower conductor coils positioned to have vertical symmetry, are disposed on sides of the propulsion conductor coils facing the superconducting coils and are arranged at predetermined intervals along the direction of travel of the vehicle. The upper and lower coils of each of these levitation-guidance conductor coils are null-flux connected, and opposing ones of the these levitation-guidance conductor coils arranged on the opposed side walls of the track bed are null-flux connected. The upper and lower conductor coils of the levitation-guidance conductor coils are set in such a manner that mutual inductance between the superconducting coils on one side of the vehicle and the opposing levitation-guidance conductor coils on one side wall of the track bed and the mutual inductance between the superconducting coils on the other side of the vehicle and the opposing levitation-guidance conductor coils on the other side wall of the track bed cancel each other out when the vehicle is running on auxiliary wheels.

In an electronic still camera system, a plurality of circular tracks are performed on a magnetic disc and the magnetic head 1 is used for both reproduction and erasing of the disc. When any one of the tracks is selectively erased, the reproducing operation is set by a control circuit 16 and tracking control of the magnetic head 1 is performed by a tracking servo circuit 5 of a Dither system. The DC component of a tracking control signal in an on-track state, that is, a signal DC' showing the average trace position of the magnetic head 1 on the disc is held in a sample and hold circuit 8. In addition, an oscillator 10 generates an AC signal AC' with an amplitude which moves the magnetic head 1 by the predetermined maximum amount d of track deviation. After a lapse of a predetermined period, tracking control of the magnetic head 1 is performed by a combined signal of the DC signal DC' and the AC signal AC' and reproduction operation is switched into erasing operation, so that the target track is erased.

A silencer for a motorcycle has a front cup which has a tapered tubular shape, a center sleeve which is connected to the front cup, and a tail cup which is connected to the center sleeve. Since the front cup has a tapered tubular shape, the front cup is arranged such that a front end of the front cup is positioned in the vicinity of a main frame. A distal end of the silencer can be shifted frontward in the longitudinal direction of a vehicle compared to a silencer of a prior art. As a result, a length of the silencer can be increased while avoiding interference between the silencer and legs of a rider and hence, silencing performance of the silencer can be enhanced. Since the distal end of the silencer can be shifted frontward in the longitudinal direction of the vehicle, the concentration of a mass can be acquired.
