Abstract: A semiconductor device is configured to increase energy absorbed by an active clamp. The semiconductor device comprises a semiconductor element, a sealing resin, and a coating member. The semiconductor element includes a first electrode. The sealing resin covers the semiconductor element. The coating member is interposed between the first electrode and the sealing resin. The coating member contains a material with higher thermal conductivity than the sealing resin.

Abstract: A Compton camera includes a scattering detection unit, an absorption detection unit, a signal processing unit, a first shield unit, and a second shield unit. The scattering detection unit detects Compton scattering of incident radiation emitted from a radiation source. The absorption detection unit detects absorption of incident radiation that has undergone Compton scattering at the scattering detection unit. The signal processing unit obtains an image of the radiation source based on coincident detection events of Compton scattering of radiation at the scattering detection unit and absorption of radiation at the absorption detection unit. The first and second shield units are provided between the scattering detection unit and the absorption detection unit. The first shield unit selectively allows forward-scattered radiation to pass and selectively blocks back-scattered radiation.

Abstract: A control for robots wherein a plurality of control units are connected in a hierarchical structure including a plurality of ranks including the lowest rank, and the robots subordinate to the control units belonging to the lowest rank.

Abstract: A system for teaching, controlling and monitoring industrial robots includes a storage section storing data describing working positions and motion patterns of the robots, and a teaching section for automatically preparing a teach data of each robot by selecting one of the different working positions and one of the motions patterns for the robot in accordance with the kind of work. The system may further includes a graphic processor for displaying picture images of the robots, their tools and workpieces, and a checking section for searching for robot-robot interference by checking a collection of data describing spaces occupied by the robots, and modifying the teach data to avoid such an interference.

Abstract: A manipulator features the use of a single motor and a plurality of flexible cables which are interconnected with the motor via a plurality of clutches which can be selectively engaged and disengaged. The cables transmit rotational energy to elements of the manipulator via translation devices which convert the rotational motion into linear motion.
