Abstract: A structure of a sign pole is provided. The sign pole includes a tubular member that has a predetermined outer diameter, a predetermined inner diameter, and a predetermined thickness. In a state in which the sign pole is embedded in a ground, the sign pole includes a reinforcement portion having a thickness different from the predetermined thickness while maintaining the predetermined outer diameter in a first range from a first position equal to or lower than a level of a ground surface to a second position located a predetermined distance above the level of the ground surface. The reinforcement portion has a thickness larger than the predetermined thickness.

Abstract: A magnet-type transportation system of a car-side primary type includes a rail of a magnetic material, fixedly laid down along a traveling track, and a power car capable of self-movement by a plurality of wheels adapted to roll over the traveling track. The power car includes a plurality of magnet belt conveyor units, each having a magnet belt extended in an endless manner around a driving wheel and a driven wheel. The power car also includes a power unit and a power transfer/transmission mechanism for driving each conveyor unit. The power car is adapted so that the magnet belts mounted thereon are magnetically attracted to the rail.

Abstract: The carrier for linear motor vehicle-borne field magnets includes a aluminium profiled material of a gate shape in section, which is provided with recesses of permanent magnet size in both its legs. Permanent magnets attached to iron cores are inserted into the recesses in such a way that the N and S poles thereof are opposite to each other and alternate in the longitudinal direction of the carrier frame to form a spatial magnetic field by the alternation of the N and S poles between both the legs of the carrier frame, which interacts with the moving magnetic field created by ground-side coils to generate driving power. The carrier further includes support wheels, guide wheels and a vehicle support on which a vehicle is placed.

Abstract: An electric power supplying system for a continuous transit system by magnet (CTM) in which magnets attached to under parts of a certain number of cars comprising the trains and energized regularly are attracted to magnetic belts of a plurality of magnetic belt conveyor units arranged at predetermined intervals along a running track thereby successively drawing and running the trains. There is provided a trolley wire which is divided at least into a certain number of insulated sections at intervals of a predetermined block section length and a predetermined no-load current is supplied to the insulated sections of the trolley wire. When the current flowing to each insulated section of the trolley wire is within a predetermined range, the magnetic belt conveyor unit group corresponding to a block section following the insulated section with respect to the direction of train movement is operated.

Abstract: A method for positioning seamed balls each having an endless curved seam line, comprising steps of: supporting each ball to locate its center at an origin of a three-dimensional orthogonal coordinate consisting of two horizontal axes X, Y and one vertical axis Z; rotating the ball on at least one of the axes X, Y until an optical sensor disposed on the axis Z specifies such a particular locus that intersects the seam line at four points during one full rotation of the ball to provide four arcs along the locus; finding the shortest arc among the four and locating its mid point on the axis Z by rotating the ball on the axis X; rotating the ball on the axis Y so that an intersection of a bisector and a part of the seam line is located on the axis Z; and rotating the ball on the axis Y until a hip center of the ball is located on the axis Z.

Abstract: A belt conveyor transportation system includes a plurality of belt conveyor units each having an endless belt whose main constituent element consists of a magnetic material so as to be magnetically attractive with magnets, and the conveyor units are continuously arranged lengthwise along a desired transportation network layout to form a conveyor line. The conveyor units of the conveyor line drive their magnetic belts separately or in groups each including a number of the units at an independent speed. A moving body or bodies are arranged to move along the conveyor line, and the moving member includes a magnet system. By virtue of the magnetic attraction between the conveyor units and the magnet system, the moving member travels along the conveyor line while being hauled by the magnetic belts of the conveyor units at their respective speeds.

Abstract: A control system for automatic operation of travelling objects through a power supply system without using any signal communication systems. Either a DC power source or three-phase AC power source is utilized as a power source. With the system employing a DC power source, three trolley wires are installed, one a negative and two positive. Each of the positive wires is divided and insulated into sections of a predetermined length; the positive feeding trolley wires in each section is always supplied with the DC power, and the power to the other positive feeding trolley wire is switched on and off depending on the movement of travelling objects. Each travelling object is supplied with power by the three trolley wires has a DC motor, and when one of the positive wires has no voltage, this is detected and the braking is effected. The travelling object entering a station is automatically decelerated and stopped.
