摘要:
A micromanipulator system is comprised of a microscope, a micromanipulator for three-dimensionally manipulating a fine instrument in the field of the microscope, image pick-up device for picking up an image within the microscopic field, reference position setting device for setting a reference position of the micromanipulator along a height direction, detecting device for detecting a height position of a tip portion of the manipulator as positional information measured from the reference position along the height direction, and a display device for combining the image of the image pick-up device with the positional information detected by the detecting device to display the combined image thereon. The joy stick includes a manipulating lever, X- and Y- axial direction detectors, a control signal generation device, and a push button switch. The manipulating lever is swingable in an arbitrary direction with the center of a base. The X- and Y-axial direction detectors detect the inclined angle and the neutral position of the manipulating lever. The control signal generation device outputs a position control signal or a speed control signal on the basis of the detection result of the detectors. While the push button switch is not being depressed, the mode is a position control mode for outputting the position control signal. Also, when the push button switch is depressed, the mode is changed to the speed control mode for outputting the speed control signal. The system enables a micromanipulator to be controlled at an arbitrary angle, thus improving operability.

A micromanipulator system has a stepper motor driven at a microstep, and having a stepping angle which is subdivided in units of a predetermined reference subdivision. A micromanipulator moves an instrument by the stepper motor, and an input device inputs either a moving speed of the fine instrument or a moving position thereof. A present position calculating device calculates a present position of the stepper motor in a virtual subdivision unit which is obtained by subdividing the reference subdivision unit to a preselected subdivision number. A speed calculating device calculates a drive speed of the stepper motor based either on the moving speed or the moving position, which are entered from the input device. An output pulse setting device determines a target output pulse, and an energizing signal outputting device energizes the stepper motor in response to the target output pulse. The stepper motor is independently provided on the micromanipulator so as to move the fine instrument in a plurality of axial directions. A moving ratio calculating device calculates a ratio of moving amounts along the axial directions based upon a moving angle of the fine instrument. The input device calculates either the moving speed or the moving position along the respective axial directions based upon the ratio of moving amounts.

A micromanipulator system has a microscope, a micromanipulator for three-dimensionally manipulating a fine instrument in the field of the microscope, an image pick-up device for picking up an image within the microscope field, reference position setting device for setting a reference position of the micromanipulator along a height direction, a detecting device for detecting a height position of a tip portion of the manipulator as positional information measured from the reference position along the height direction, and a display device for combining the image of the image pick-up device with the positional information detected by the detecting device to display the combined image thereon. A joystick effects movement in each axial direction of the micromanipulators allows for precise positioning of a fine instrument positioned on the micromanipulator. The system also has an angle setting device for setting the movement angle with respect to specimens in a petri dish disposed on a portion of the micromanipulator system. The joy stick includes a manipulating lever which is swingable in an arbitrary direction with the center of a base. X- and Y-axial direction detectors detect the inclined angle and the neutral position of the manipulating lever. A position control signal or a speed control signal is output based on detection result of the detectors. The micromanipulator system includes a stepper motor driven at microsteps, and other elements which enable control at arbitrary angles, which improves operability. The micromanipulator is configured to be driven at a constant frequency with variable speed, and under continuous speed control, without employing a high frequency oscillator.

A door member such as a garage door is driven by a motor through a roller chain having a finite length to travel in the garage opening and closing directions. The roller chain is driven by a single drive sprocket driven by the motor to make its reciprocating movement along the same path while making rolling engagement at its roller portion with a guide rail constructed to support the roller portion of the roller chain from the opposite sides. A trolley connected to the door member by an arm is releasably coupled to the roller chain and is also guided along the guide rail while making sliding engagement therewith. A mechanism for detecting abutment of the door member with an obstruction present on the traveling path is provided to detect the above situation when a physical force is imparted to the roller chain due to the abutment. The opening and closing movement of the door member, stopping of rotation of the motor and detection of the presence of an obstruction are electrically controlled.
