Abstract: The present invention is made to provide a rotation angle detecting sensor capable of being miniaturized. The rotation angle detecting sensor includes a rotating body; an encoder structure 3 having n (n represents a positive integer) cycles of phases each ranging from phase 0° to phase 360°, each phase being formed by periodically changing the width of the conductor pattern; and a sensor body having a plurality of inductance elements C1, C2, C3, C4 and disposed opposing the encoder structure 3 with a space. The cycle number n of the phase of the encoder structure 3 is a positive integer equal to or greater than three, the plurality of inductance elements C1, C2, C3, C4 have a phase difference of 90 degrees therebetween, and the two adjacent inductance elements are disposed apart from each other by a space of at least half a phase of the encoder structure 3.

Abstract: A motor having a sensor to detect a rotation angle that enables reduction in size and weight is provided. The motor may include a reduction gear having a planetary gear, which is provided between a rotor and a rotation axis of the motor, a conductor pattern periodically changing in width, which is formed on a surface perpendicular to the rotation axis of the rotor, and a rotation angle detection sensor, which is provided to oppose the conductor pattern.

Abstract: The present invention is to reduce the change of the position of a picture screen due to the magnification/reduction of the picture screen and occurrence of losing a part of the picture screen. The picture screen signal of a main picture screen is switched to the picture screen signal of a sub or slave picture screen to be described later when the picture screen signal of the main picture screen is supplied to a change-over switch (2) from an input terminal (1). This picture screen signal is supplied to an image receiving tube (4) through an RGB drive circuit (3). The picture screen signal of the slave picture screen is supplied to a slave picture screen signal forming circuit (6) from an input terminal (5), reduced to an arbitrary size, taken out at the timing of an arbitrary position and the picture screen signal of the slave picture screen is formed. Further, a command signal from a command unit is supplied to a microcomputer 9 through an input terminal (8).

Abstract: A fastener for securing a wheel to a shaft comprises a first ring having a cylindrical central opening. The first ring includes a radially extending portion having for engaging one side of the wheel. A boss having a tapered outer surface extends axially from the radially extending portion, and the central opening extends through the radially extending portion and through the boss. The fastener also includes a second ring for engaging the opposite side of the wheel, and a third ring having an inner surface engageable with the tapered outer surface of the boss of the first ring. Bolts connectable to the second and third rings urge the second and third rings axially toward each other whereby the second ring is urged against said opposite side of the wheel so that the wheel is axially pressed between the first and second rings, and the inner cylindrical surface of the boss is radially pressed against the shaft.

Abstract: Workpieces to be machined are stacked on all but one of a series of uniformly spaced vertical guide bars on a turntable movable along a transfer path. An elevator mechanism moves into engagement with the turntable and lifts a carrier with a stack of workpieces to be machined on one of the guide bars so that the uppermost workpiece is in a position to be grasped and transferred to a machine tool by a robot arm. The elevator also positions a workpiece carrier on an adjacent guide bar so that the carrier is positioned for the stacking of machined workpieces thereon by the robot arm. The workpiece carriers are positioned by the elevators in response to signals from photoelectric detectors. When all of the workpieces on one carrier are machined and stacked on an adjacent carrier and said one carrier is unloaded, the elevator mechanism is temporarily separated from the turntable and the turntable is rotated by the distance of twice the spacing between adjacent guide bars.
