Abstract: There is provided a crushed piece supply device including a storage tank that stores a crushed piece containing a fiber, a partition portion that partitions an inside of the storage tank into a first space and a second space positioned below the first space by narrowing the inside of the storage tank, an adjusting section that adjusts a moving amount of the crushed piece moving from the first space to the second space, a stirring section that stirs the crushed piece in the second space, and a discharge port through which the crushed piece is discharged from the second space.

Abstract: A stirring device has a storage tank and a stirring member that stirs an inside of the storage tank, and the stirring member has a humidified air release port through which humidified air, which is air humidified, is released into the storage tank.

Abstract: The present disclosure provides a vehicle back door inner panel containing synthetic resin as a constituent material. The inner panel includes an opening, an upper portion, a skirt portion, and two side portions. The opening is provided with a back window. The upper portion is closer to a vehicle top than the opening, extending in a vehicle width direction. The upper portion is provided with two door hinge portions at left and right ends. The skirt portion is closer to a vehicle bottom than the opening. The skirt portion is provided with a latch attachment portion at a lower end. The side portions are on left and right sides of the opening, extending in a vehicle top-bottom direction. The side portions connect the upper portion and the side portions. The side portions have a hat-shaped cross section open toward a rear side of the vehicle. The skirt portion has two connecting portions each having a hat-shaped cross section open toward the rear side of the vehicle.

Abstract: The invention is directed to an apparatus for detecting if a distributed power supply is switched from cooperation with another power system to isolated or single operation. The distributed power supply includes a synchronous generator and possibly also another power source such as an induction generator. The single operation detecting apparatus includes a frequency detector connected to a line system of a customer, reactive power regulating equipment connected to the distributed power supply, a fluctuation signal generator for providing periodic small fluctuations to a reactive power setter of the reactive power regulating equipment, and a single operation signal generator for monitoring the output of the frequency detector to output a single operation signal when the monitored output deviates from a range between allowable upper and lower limits around a reference frequency.

Abstract: A method for detecting islanding operation of a rotating-machine type dispersed generator. The dispersed generator is interconnected with a main electric source through a circuit breaker to constitute an electric power system. The estimating method is implemented as follows: (a) changing electric power of the electric power system; (b) detecting frequency component of the electric power; and (c) deciding that an islanding operation of the dispersed generator is executed if the change of the frequency component becomes greater than a predetermined value. With this method, it becomes possible to detect the islanding operation of the dispersed generator even if the power flow at the interconnecting circuit breaker is generally zero.
