Abstract: A current detector unit has a current detecting portion detecting a current flowing between a three-phase inverter and a direct-current power supply as a detection current; a three-phase current detecting portion for detecting a three-phase current of the inverter based on the detection current; and a judging portion judging, based on the detection current, whether or not a target time point belongs to a period during which the three-phase current can be detected. If the judging portion judges that the target time point belongs to the period, the three-phase current detecting portion detects the three-phase current.

Abstract: A motorized conveyor roller prevents slip between a power transmission mechanism in a roller tube and the roller tube due to aging. The power transmission mechanism includes a first closed-bottom cylindrical member fit over a second closed-bottom cylindrical member and a bolt for axially pressing the members against one another. The first member receives torque from a motor and a double-sided tape is laid on an outer surface of the first member. Facing surfaces of the first and second members are tapered, and the circumferential wall with the double-sided tape is expandable diametrically. The bolt diametrically expands the circumferential wall pressed by the tapered surface. Thus, an adhesive force of the double-sided tape sandwiched between the circumferential wall and the roller tube is exerted to adhere the outer surface of the first member to an inner surface of a roller tube.

Abstract: A vacuum pump includes rotary shafts connected to a pair of screw-type rotors, respectively, and a pair of shaft retainers extending in the housing. Each shaft retainer supports the corresponding rotary shaft by means of a proximal bearing portion and a distal bearing portion. Each pair of the proximal and distal bearing portions are fixed in the axial direction with respect to the corresponding rotary shaft and shaft retainer. Lubricant oil is stored in an oil storage space in a gear case attached to the housing. A cooling water passage through which cooling water to cool the lubricant oil passes is formed in the gear case. A controller controls the flow rate of the cooling fluid, so that the temperature of the lubricant oil in the oil storage space is kept constant. With this configuration, when the bearing portions are fixed in the axial direction with respect to the rotary shafts and the shaft retainers, it is possible to prevent load from being applied to the bearing portions in the axial direction.
