The observation unit according to the present invention comprises an observation device observing a sample, a placing table on which the sample is placed, a drive device moving the placing table to an observation position where the sample is observed by the observation device, and a casing sealing a first space extending in a vertical direction. The first space and the placing table are arranged so as to be displaced from each other in a horizontal direction, and the drive device is arranged in the first space.

Observation unit

A force detection device of the present invention includes a handle to be given an operation force by an operator, disposed on a support reciprocatably in a first axis direction along a forward/backward direction of the truck and a second axis direction orthogonal thereto. A pair of force detection parts capable of detecting only a force in the first axis direction is disposed on the support in a spaced-apart relationship in the second axis direction. A force propagation body intervenes between both force detection parts and the handle. A part of the force propagation body passes through the inside of a gripped part of the handle. The force propagation body is coupled to the handle by a coupling axis extending in a third axis direction orthogonal to the first axis and second axis so as to be capable of relative rotation about the coupling axis.

Force detection device

A force detection device of the present invention is for detecting an operation force of an operator applied in a uniaxial direction, and includes a force receiving part for receiving the operation force, a force detection part placed on a support for detecting the uniaxial force, a force propagation body disposed reciprocatably along the uniaxial direction on the support for propagating the operation force received by the force receiving part to the force detection part, a guide provided on the support for guiding reciprocation of the force propagation body, a preload receiving part pivoted to the force propagation body and capable of swinging within a plane along the uniaxial direction, and a pair of coil springs coupled to both sides of the preload receiving part with a pivot axis thereof held therebetween for giving a preload to the force detection part.

The invention provides a mobile carriage which is adapted to shift the center of gravity efficiently by utilizing the weight of wheel rotating means, power source means and control means to thereby increase the weight of a weight portion and reduce the increase in the weight of the entire carriage, the carriage comprising a base frame, a front wheel and a rear wheel which are disposed under the base frame, wheel rotating means coupled to the front wheel and the rear wheel for rotatingly driving the wheels, power source means for the wheel rotating means, center-of-gravity shifting means having a weight portion disposed above the base frame and a mechanism for moving the weight portion relative to the base frame to shift the position of the center of gravity of the base frame by moving the weight portion by the moving mechanism, and control means for controlling the wheel rotating means and the moving mechanism, the carriage being characterized in that at least one of the wheel rotating means, the power source means and the control means is utilized as the weight portion of the center-of-gravity shifting means.

A user communicates with a companion with his or her portable telephone attached to a telephone attachment pocket of a robot. The robot acts in accordance with a voice signal which is outputted from the portable telephone, thereby behaving as if it were speaking to the user. The robot outputs a voice in response to the user's voice which is picked up by a microphone, thereby behaving as if it were listening to the user. Owing to this robot or a robot system using the same, the user feels less odd in his or her communication using the portable telephone.

Charging system for motor-driven vehicle

The invention provides an electric bicycle comprising an electric motor mounted on the body of the bicycle between the saddle and the outer periphery of the rear wheel, and a belt transmission mechanism for transmitting the rotation of the motor to the rear wheel on speed reduction. The belt transmission mechanism comprises a drive pulley provided between the saddle and the outer periphery of the rear wheel for receiving the power of the motor, a driven pulley having the same diameter as the rim of the rear wheel and rotatable with the rear wheel alongside the rim, and a belt reeved around the drive pulley and the driven pulley. These components realize a simple construction wherein the rotation of the motor can be transmitted to the rear wheel as reduced to the desired speed in a smaller number of stages.
