A semiconductor module structure includes: a semiconductor element portion including a plurality of capacitor elements; two bus bars sandwiching the semiconductor element portion and being electrically connected to the semiconductor element portion; and cooling fins, which are conductive, formed on respective surfaces of the bus bars at positions sandwiching the semiconductor element portion. Further, insulating refrigerant is provided in the cooling fins.

Semiconductor module structure

Provided are a semiconductor element bonding apparatus and a semiconductor element bonding method that do not cause a bonding material to protrude and also ensure adhesion, even when there are variations in a thickness of a semiconductor element or a workpiece and even when there are projections and depressions on surfaces. A semiconductor element bonding apparatus includes disposing means for disposing a workpiece and a semiconductor element at positions facing each other, moving means for moving the workpiece or the semiconductor element in a vertical direction, displacement measuring means for measuring displacement of the workpiece or the semiconductor element in the vertical direction, load measuring means for measuring a contact load between the workpiece and the semiconductor element with the bonding material interposed therebetween, and elastic modulus calculating means for calculating an elastic modulus from results of the measurement by the displacement measuring means and the load measuring means.

Semiconductor element bonding apparatus and semiconductor element bonding method

A control method for a power assist device provided with an operation handle, a force sensor that detects an operation force applied to the operation handle and an orientation of the operation force, a robot arm, and an actuator. When the orientation of the operation force is detected to be within a predetermined angle range with respect to a preset advancing direction of the operation handle, the actuator is controlled so as to move the operation handle along the advancing direction by employing only a component of the operation force along the advancing direction; and when the orientation of the operation force is detected to be outside the predetermined angle range, the actuator is controlled to move the operation handle by the operation force applied to the operation handle and the orientation of the operation force.

Power assist device and control method therefor

A method of controlling a power assist device that includes an operating handle, a force sensor, a robot arm, an actuator that drives the robot arm, and a conveying portion for conveying the robot arm. When a body in motion, the conveying portion is controlled to move in synchronization with the body, and when the motion of the body is stopped or has resumed, the drive of the robot arm is stopped for a predetermined time, and does not resume until after a predetermined time has elapsed.

Power assist device and method of controlling the power assist device

According to a work mounting method by the work transfer apparatus of the prior art, a glass plate or a work may fail to abut against a window frame homogeneously at its peripheral edge portion, and the adhesion strength or the sealing property between the glass plate and the window frame may not be retained all over the periphery of the adhered portion. Provided is a work transfer apparatus, which grips a rear glass by its gripping member and mounts the rear glass while pushing the gripped rear glass onto the window frame of a car body by the action of a supporting arm. The work transfer apparatus comprises a control device, and each of absorption pads of the gripping member includes a force detecting sensor for detecting the force to be applied to the absorption pads. The control device controls, when it uses the work transfer apparatus to mount the rear glass on the window frame, the actions of the supporting arm on the basis of the magnitude of the detected value of the force detecting sensor of each absorption pad.

Work transfer apparatus, and work mounting method

If the rotation angle in a rotation direction allowed by a joint portion detected by the angle sensor is no more than a predetermined lower limit or no less than a predetermined upper limit, the controller maintains the released state of the brake mechanism so that the rotation of the workpiece in the direction is not restricted.

Power assist apparatus with a controlled brake mechanism for positioning a workpiece and control method thereof

In a control method for a power assist apparatus, a pressing force acting on a workpiece held by a workpiece holding apparatus is detected, a determination is made as to whether or not the detected pressing force exceeds a preset threshold, a determination is made as to whether or not a dead man switch provided on the workpiece holding apparatus is ON, and a determination as to whether or not to release a rotation restriction applied to a joint portion for connecting the workpiece holding apparatus rotatably to an arm is made in accordance with a result of the determination as to whether or not the detected pressing force exceeds the preset threshold and a result of the determination as to whether or not the dead mean switch is ON.
