Abstract: A coin processing device includes: a feed belt that normally rotates in contact with the upper side of a coin to convey the coin to a conveyance passage extending from an inlet-side passage portion to an outlet-side passage portion; a conveyance motor that normally rotates the feed belt during the normal rotation; a detection unit that detects the coin passing through a position determined in advance in the conveyance passage; and a control unit that switches the conveyance motor from a first rotation state where the conveyance motor normally rotates at a first rotation speed to a second rotation state where the conveyance motor normally rotates at a second rotation speed slower than the first rotation speed, in response to detection of the coin by the detection unit, and then rotates the conveyance motor.

Abstract: A construction machine comprises an electric motor/generator coupled to an electricity accumulator, an engine, a transmission coupled to drive wheels, an epicyclic gearing for coupling an output shaft of the electric motor/generator, an output shaft of the engine, and an input shaft of the transmission, the engine torque and/or the generator torque being transmitted to drive wheels, a clutch for directly coupling two among the output shaft of the electric motor/generator, the output shaft of the engine, and the input shaft of the transmission, and a controller configured to, under a condition in which the clutch is in an off-state, control engine speed based on the degree to which the accelerator is open and on the amount of electricity in the electricity accumulator, to control shifting of the transmission gear position based on the accelerator opening degree, operational state of the generator, and the electricity amount.

Abstract: A probe for measuring the concentration of an impurity in molten iron is disclosed. The probe comprises three sensors. The first sensor measures the activity of the impurity element directly. The second sensor measures the activity of free oxygen. The third sensor measures carbon content. These values are used are used to give a compensated measure of the impurity element.
