Abstract: While a power storage installation operates as a virtual generator to maintain an power storage amount, a power generating installation calculates a first generated power change rate command value from a deviation between a frequency of a power distribution system and a frequency command value, calculates a second generated power change rate command value from received power measured by a received power measurer, calculates a second active power command value by integrating a generated power change rate command value to which the first generated power change rate command value and the second generated power change rate command value are added, and controls an output of the power generating installation based on the second active power command value.

Abstract: An injection molding method for a molded item uses a polyether ether ketone (PEEK) material, wherein a filling peak pressure is 40 MPa to 150 MPa. The PEEK material may be injected to form the molded item from a runner member through a multipoint gate and then optionally a subrunner. The runner member and the subrunner may be connected to each other by a film gate. A stretching processing may be applied after the PEEK material is injected to increase a length 1.2 to 5 fold and increase a diameter to 0.2 mm to 1.0 mm. The stretching processing may use an in-mold stretching method.

Abstract: When an AC line of one local system and a power system are in a parallel-off state, a control device included in a power supply system causes local inverter devices of the local systems to operate in a parallel-off operation mode in which control is performed such that the voltage and frequency of power on the AC line is at a target voltage and a target frequency determined according to the state of charge of a power storage device. When a condition for switching to the connected state has been satisfied, the control device stops operation of the local inverter device in the parallel-off operation mode and causes a switch to the connected state by operating the interrupting device, and thereafter causes the local inverter device to operate in a charging operation mode used in charging the power storage device with supplementary power received from the power system.

Abstract: A magnetic clutch 1 having a rotor 2, an armature 3 having a friction surface 31 disposed opposite and engaged by the friction surface 21 of the rotor 2, an electromagnetic coil 4 for attracting the armature 3 to the side of the rotor 2, and a rubber hub 5 for transmitting the rotational power to driven equipment. The rubber hub 5 is composed of an outer hub 51 fixed to the armature 3, an inner hub 52 connected to the driven equipment, and a rubber part 53 disposed between the outer hub 51 and the inner hub 52. On a surface of the armature 3, a corrosion-preventive coated film is formed by electrodeposition-coating. A powder coated film 6 having a function of preventing adhesion between the armature 3 and the rubber part 53 is formed on a surface of the outer hub 51, on a surface of the inner hub 52, and on a rubber seating surface 531 of the rubber part 53.

Abstract: A lock member attachment device with a needle guard installation structure includes a needle guard having a pair of fork-like attachment pieces at a basal portion thereof, and a boxlike needle receiving portion at least at an upper surface thereof. The needle receiving portion is at a front portion of an attachment piece. The pair of attachment pieces are pivotally supported on an area near a front end of a main body casing, and at least one of the attachment pieces is acted on by a slider-type stopper, thereby retaining a predetermined position. The needle receiving portion has a cut groove formed in a bottom portion thereof, the cut groove being for restraining a discharged runner portion of a tag suspending member assembly when the needle guard is collapsed in use, so that a finger holding a grip of the main body will not contact the runner portion.
