Abstract: A crane operation assistance system includes: a scanning-type distance meter capable of measuring a distance and an angle between the distance meter and an object under a range of movement of a movable body that can hoist a container and move in a horizontal direction; and object height distribution data making means for making, based on the information measured by the distance meter, object height distribution data that is data indicating a distribution of heights of objects under the range of movement of the movable body. If a blind spot for the distance meter has occurred, the object height distribution data making means revises data of object heights in the zone of the blind spot based on data of an object height at a point that is farthest from the distance meter in a imaginary containers presence zone having an overlap with the zone of the blind spot.

Abstract: A cooling device for cooling heat generating elements in which a cooling effect is produced by collision of a coolant with the back face side of the heat-generating elements. The coolant can be introduced into a coolant introduction chamber and is then introduced into a first coolant contact chamber by injection from a central nozzle. Thereafter the coolant produces a cooling effect in a second coolant contact chamber and in a third coolant contact chamber. Peripheral nozzles are formed so as to spread in radial fashion about the central nozzle and to provide uniform cooling of the back face side of the heating-generating elements.

Abstract: A cooling device for cooling heat generating elements in which a cooling effect is produced by collision of a coolant with the back face side of heat-generating elements (1). The coolant (10) is introduced into a coolant introduction chamber (3) within a first coolant contact chamber (4) and is then introduced into the first coolant contact chamber (4) by injection from a central nozzle (7). Thereafter the coolant (10) produces a cooling effect in a second coolant contact chamber (5) and in a third coolant contact chamber (6). Since peripheral nozzles (8) and (9) are formed so as to spread in radial fashion about central nozzle (7), uniform cooling of the back face side of the heating-generating elements (1) is observed. As a result, there is no possibility of large tensile heat stress being generated at the heat-generating elements (1).

A plurality of apertures (15) is formed in the first electrode, in which are positioned bosses (16) being continuous with the second electrode (13), while the plurality of unit capacitors (1) is arranged on the first electrode (12), one terminal of each unit capacitor (1) being in contact with the first electrode (12) and the other with the second electrode (13) via a boss (16) so as to connect all the unit capacitors (1) electrically in parallel fashion. In this manner a mounting structure for capacitors is provided which permits of high capacity in a compact form.

Abstract: A cooling effect is produced by collision of coolant (10) introduced into coolant introduction chamber (3) with the back face side of heat-generating elements (1) within a first coolant contact chamber (4) by injection from a central nozzle (7). Thereafter in the same way coolant (10) produces a cooling effect in a second coolant contact chamber (5) and third coolant contact chamber (6). Since peripheral nozzles (8) and (9) are formed so as to spread in radial fashion about central nozzle (7) as center, cooling is effected to practically the same level of temperature, so there is no possibility of large tensile heat stress being generated at heat-generating elements (1).
