Abstract: An information processing device includes a communication unit and a control unit. The control unit is configured to determine a sprinkling mode based on information indicating the environment of a sprinkling place. The control unit is configured to send, through the communication unit, a notification indicating the sprinkling mode to at least one vehicle scheduled to travel in the sprinkling place.

Abstract: In a motor power transmission device (30), wherein rotational power of an electric motor (40) is input to a sun gear (51) of a planetary speed reducer (50), and then the rotation of the sun gear (51) is converted to rotation of a planetary carrier (55), and wherein the planetary carrier (55) rotatably supports planetary gears (61, 62) and converts revolving motion of the planetary gears (61, 62) into rotating motion, and the rotation of the planetary carrier (55) is then output to an output shaft (15), a torque limiter mechanism (57) is interposed between the planetary carrier (55) and the output shaft (15). Thus, even if excessive back torque is input to the output shaft, transmission of the back torque to the speed reducer is blocked to protect the speed reducer.

Abstract: A control apparatus for a motor-assisted bicycle detects a pedaling torque applied to a crankshaft with a pedaling force sensor, controls a motor unit in a regenerative control process to charge a battery if the torque value of the detected pedaling torque is equal to or smaller than a predetermined level, and controls the motor unit in an assistive control process if the torque value is greater than the predetermined level. The control apparatus controls the motor unit in the regenerative control process at a crankshaft angular position in which the torque value detected by the pedaling force sensor is equal to or smaller than the predetermined level, and switches from the regenerative control process to the assistive control process for controlling the motor unit at a crankshaft angular position in which the torque value detected by the pedaling force sensor becomes higher than the predetermined level.

Abstract: A thermoelectric conversion unit can easily be attached to and detached from a heater, in which lower electrodes are formed on the upper surface of a lower substrate, placed in opposition to an upper substrate, on the lower surface of which are formed upper electrodes; end faces of thermoelectric elements are bonded to both the electrodes to form a thermoelectric conversion module. A heat-absorbing member having a protruding engagement portion is installed on one of the substrates of the thermoelectric conversion module, and a heat-releasing member is installed on the other substrate, to form a thermoelectric conversion portion. A heat-conducting portion having a engagement hole portion is installed on the outer peripheral surface of a lamp, to form the light-source lamp portion. By engaging the protruding engagement portion with the engagement hole portion, the light-source lamp portion can be detachably attached to the thermoelectric conversion portion.

Abstract: A thermoelectric module is constituted by a pair of substrates having electrodes, which are arranged opposite to each other with a prescribed space therebetween, in which a prescribed number of thermoelectric elements are arranged in such a way that a p-type and an n-type are alternately arranged, so that the thermoelectric elements are connected in series or in parallel together with the electrodes. Herein, one substrate is a heat absorption side, and other substrate is a heat radiation side. In addition, a current density in a current transmission area of the heat-absorption-side electrode is set to 50 A/mm2 or less, and a height of the thermoelectric element is set to 0.7 mm or less. Furthermore, a temperature-controlled semiconductor module can be realized by combining a thermoelectric module with a semiconductor component such as a semiconductor laser.

Abstract: In construction of a composite golf club head made up of several shell components united together along their mating edges, a face shell component is made of titanium alloy and a rear shell component is made of pure titanium. The titanium alloy well withstands hard impact at shooting balls by a face whereas use of cheep pure titanium allows plastic shaping of the intricate rear shell component even at a low temperature to significantly lower the total production cost of the golf club head.
