摘要:
An exposure rate controlling mechanism for a camera comprising an iron member controlled to move to more than three attracted/departed positions by an electromagnet and a mechanism for controlling the exposure rate corresponding to the position to which the iron member moves. The mechanism for controlling the exposure rate comprises an exposure rate controlling member which is moved to a position corresponding to the position to which the iron member moves and an exposure rate determining member which is controlled to move by an amount corresponding to the amount of displacement of the exposure rate controlling member.

A shoe also usable as a stool is a so-called boot-shaped shoe. In the boot-shaped shoe, a circumference of a heel and a legging rear part of the boot shape sustains an upright posture made of a hard and strong material. A seating part is provided in a top part of the boot shape so as to project horizontally rearward, so that, when the person wears the boot-shaped shoe and squats down on the seating part, and the person is able to sit on the seating part as a stool.

A system is provided for controling a robot operating in association with a rotary table, including a robot, a rotary table, and a control circuit. The control circuit carries out a step of composing and storing teaching data as values on a rotary table orthogonal coordinate system (UVW axes), the rotational shaft of the rotary table being the vertical (W) axis, a step of calculating the UVW coordinates of a plurality of interpolation points by carrying out path interpolation along a line and/or curve defined by the stored teaching data, a step of calculating the degree of rotation of the rotary table which is required to bring each of the interpolation points into the U-W plane, a step of computing the UVW coordinates of the positions that the interpolation points occupy as they pass through the U-W plane, a step of transforming the data obtained by the computing step from coordinates in the UVW coordinate system to coordinates in a robot assigned coordinate system (XYZ axes) or orientation positions of the joint axes of the robot, and operating the robot in accordance with the information thus derived.

Synchronous operation of a multi-joint robot and a rotating table is facilitated by the provision of a multi-joint robot controller. The robot controller detects the position of an arm of the multi-joint robot relative to a coordinate system assigned to the multijoint robot and the position of a specific point on the rotating table relative to the same coordinate system. The spatial relationship of the table relative to the multi-joint robot is calculated based on the coordinates of a plurality of positions of the specific point on the rotating table.

The present invention provides a rotation detection apparatus of a rotational axis connected to an output axis system of a reduction gear to count the rotation of a rotational axis driven rotationally, including a reduction gear, with an integer reduction ratio, whose rotational axis of a driving source is connected to an input axis. The apparatus provides a position signal once every rotation of the output axis, and a rotation angle signal in response to the rotation angle of said input axis is output to correlate said output position signal with one of said rotation angle signals to count the rotation of the rotational axis by these position and rotation angle signals. An accurate rotation can be detected even at one-way high-speed rotation.

A bell head of a rotary atomizing electrostatic coating apparatus includes a bell head body made from high electric resistance material, a semi-conductive layer formed on an outside surface of the bell head body, and a high electric resistance layer formed on an outside surface of the semi-conductive layer. The high electric resistance layer is also of a chemical-proof and of a thinner-proof type.

This invention is a real-time tracking controller for a standard-path robot that detects a target point in advance, permitting higher-speed work. The robot uses both sensed data and previously taught data to accurately execute its task. Accurate control is obtained using target points corresponding to time intervals. Thus, even if the speed or path is changed during operation, accurate tracing is continuously executed.

An exposure control unit including an element having electrostrictive properties and a fixed end and a deformation quantity of which is determined in accordance with a voltage applied thereto drives a programming shutter provided with shutter blades having the function of the diaphragm by a driving source composed of the deformation produced at a free end of the electrostrictive element when the voltage is applied to the element. The shutter blades having the function of the diaphragm are opened by the deformation produced at the free end of the electrostrictive element in accordance with the voltage applied to the element and the voltage is increased with the lapse of time in interlocked relationship with the opening operation of the shutter blades so that the electrostrictive element is gradually deformed and the shutter blades are also gradually opened. The electrostrictive element is then short-circuited at a time when a proper exposure is obtained so that the exposure operation is immediately terminated.

A device is provided for indicating fading operation in cinecamera. A control circuit receives the scene light indicating voltage and a manually adjusted output voltage for operating a diaphragm driving means to adjust the aperture to a proper value for the scene brightness an RC circuit is connected to the diaphragm control circuit which selectively applys either a constant charging or discharging voltage to the diaphragm control circuit, this causes the control circuit to drive the diaphragm to continuously vary the aperture for effecting the fading-out and the fading-in of the scene. A first comparator receives the output voltage of the RC circuit and the output voltage of the diaphragm control circuit and produces a signal when both voltages are coincident. A second comparator connected to the RC circuit produces a signal when the output voltage of the RC circuit reaches a constant charging an indicator receives the output signals of the first and the second comparator for indicating the completion of both fading-out and fading-in of the scene.
