Abstract: This behavior planning device includes: an emergency stop requesting unit which detects abnormality on the basis of obstacle information acquired from an obstacle information acquisition unit and a roadside information acquisition unit and outputs an emergency stop request; a stop position determination unit which calculates a stop position of an own vehicle on the basis of the emergency stop request and determines whether or not the stop position is in an area where advancement of another traffic participant is obstructed; and a behavior plan generation unit which, in a case where it is determined that the own vehicle will stop in the area where advancement of another traffic participant is obstructed, such as an intersection, generates a behavior plan for causing the own vehicle to stop outside the area or after passing over the area.

Abstract: A robot includes a base attached to an end of a robotic arm, a conveyor fixed to the base, and a holder to hold a workpiece and place the workpiece on a transferring surface of the conveyor. The holder includes a pivot shaft extending along the conveyor in a transferring direction of the conveyor, and reciprocatable or telescopic in the transferring direction, a pivoting structure attached to the pivot shaft so as to be reciprocatable in the transferring direction, and pivotable centering on the pivot shaft in a plane in which a width direction perpendicular to the transferring direction intersects with a height direction perpendicular to the transferring direction and the width direction, and a holding structure upstream of the pivoting part in the transferring direction to hold the workpiece.

Abstract: Cutting machining is performed on a workpiece by making a cutting tool travel relative to the workpiece while rotating the cutting tool such that a peripheral speed of the cutting tool becomes equal to or more than a cutting speed of the cutting tool, while an outer peripheral surface and an end surface of the cutting tool function as a rake surface and a relief surface, respectively.

Abstract: A machining assist system includes a knowledge database, a receiver, a control unit, and a display. The knowledge database stores various pieces of information indicative of know-how concerning a machining method and a machining facility. The receiver receives a question. The control unit executes a driving solver and a solution-providing solver so as to search the knowledge database using a search condition based on the question and derive a response. The display presents the response. The response includes a plurality of measures, priorities assigned to the measures, and progress information indicative of a search process and a search route. The search process includes a plurality of factors to be used to derive the measures. The search route is a link between the factors. The search process and the search route are visually presented on the display.

Abstract: A sintered product based on mesocarbon microbeads is prepared by pressure-molding mesocarbon microbeads (MCMB) having an MSP (maximum solubility percent) value of 30 to 38% by volume whereby a body is formed, and sintering the body, wherein MSP represents the percentage volume reduction (volume %) determined by heating a given amount of an MCMB to 350.degree. C. under a pressure load of 10 kgf/cm.sup.2. The quality of a molded MCMB sintered product can be controlled by determining the percentage volume reduction (MSP) of an MCMB by heating it under a given pressure load in a predetermined space using the MSP value so found as an indicator.
