In a movement direction control apparatus and a non-transitory computer readable medium, a reaction torque accompanying rotation of a rotor is utilized to control a rotation angle of a body in a yaw direction. A specification of a yaw angle of a wheel as a target of the movement direction is received, and information of a friction torque is acquired. A rotation angular acceleration in the yaw direction is calculated, based on the yaw angle, the specification of which has been received, and the reaction torque is calculated, based on the calculated rotation angular acceleration in the yaw direction. An operation instruction to a motor for yaw is generated, based on the calculated reaction torque and the acquired information of the friction torque.

Movement direction control apparatus and computer program

An aligning device for electronic components and a bonding device using the aligning device. The aligning device includes a chamber, a flexible bellows within the chamber, two block used to hold an electronic component, a driving unit configured to move either of the two blocks relative to each other and located in an airtight chamber and an image port having a window through which one of the electronic components can be observed.

Aligning device and bonding apparatus

A falling prevention controlling device includes a wheel, and a main body arranged to swing in a pitch direction and a roll direction above the wheel, an advance/retreat command receiving unit arranged to receive an advance or a retreat command of the wheel, a target pitch angle calculating unit arranged to calculate a target pitch angle based on the received command and a rotation velocity deviation in the pitch direction derived from the detected rotation angle, a pitch inclined angle estimating unit arranged to estimate a pitch inclined angle with respect to a balanced state, from the detected pitch angular velocity and a pitch torque command generated based on the target pitch angle, and a pitch torque command generating unit arranged to generate the pitch torque command based on the target pitch angle and the pitch inclined angle.

Falling prevention controlling device and computer program

A feeder for chip components is provided wherein the chip components can be supplied with high stability even in high-speed operation by operating a conveying member at a lower speed than that of a chip mounter and operating the conveying member even when the chip mounter is stopped. The chip components on a belt are supplied in one direction by lowering a feed lever according to the input load from a chip mounter so as to drive the belt connected to the feed lever via a transmission mechanism intermittently in one direction. urging means is provided for urging the feed lever in the returning direction by storing the input load of the chip mounter as energy while an eddy current damper is provided for delaying the returning operation of the feed lever relative to the returning operation of the chip mounter. When the chip mounter operates downwardly, the feed lever is moved downwardly by linking to the chip mounter while the conveyor belt is maintained in a stationary state. When the chip mounter operates upwardly, the feed lever is moved upwardly so as to be delayed relative to the chip mounter by the eddy current damper while the belt is driven at a low speed.

Feeder for chip components

A feed lever is lowered, correspondingly to the load input of a chip mounter. A rotary drum is intermittently moved through a conversion mechanism, intermittently in one direction. Chip components placed in a component accommodation chamber are aligned and discharged. When a rotation resistance larger than a predetermined value acts, a belt is slid, and breaking of a chip component is prevented.
