A drone loaded with a package takes off from a takeoff device and uses a GPS system to fly to a user house that is a delivery destination of the package as the destination. Further, when the drone approaches the user house that is the destination, the flight of the drones is switched from autonomous navigation using the GPS system to remote control performed by a landing device and an in-house control device installed in the user house. The drone lands on the landing device by remote control from the landing device and the in-house control device, separates the package, and then returns to the warehouse using the GPS system and lands on the takeoff device.

A delivery rotary-wing aircraft has a plurality of rotary wings, a central portion to which a plurality of arms for supporting the rotary wings are connected, a first mounting portion for loading a package, a second mounting portion which is located on the opposite side to the first mounting portion as viewed from the central portion, a first supporting member for coupling the first mounting portion with the central portion, and a connection portion between the central portion and the first supporting member. The center point of lift occurring in the rotary-wing aircraft with the rotation of the plurality of rotary wings and the center point of gravity of the rotary-wing aircraft coincide with the center point of the connection portion. The first supporting member is equipped with an adjustment mechanism for vertically downwardly extending the length of the first supporting member.

Delivery rotary-wing aircraft

A center C of a connecting portion coincides with a center U of lift generated in a body of a rotary-wing aircraft. The center C of the connecting portion is a point of action of gravitational force of a support rod and a first mounting portion with respect to the connecting portion. The center U of the lift is a point of action of the lift on the rotary-wing aircraft and is the center of rotation of the connecting portion.

A transmission device and reception device for digital data that have excellent resistance to noise are provided. An encoder (-) of this disclosure, included in a transmission device () of this disclosure, applies LDPC encoding to digital data using a unique check matrix for each code rate by using a check matrix in which, taking a check matrix initial value table established in advance for each code rate at a code length of 44880 bits as initial values, 1 entries of a partial matrix corresponding to an information length appropriate for a code rate of 93/120 are allocated in the column direction over a cycle of 374 columns. A demodulator () of this disclosure, included in a reception device () of this disclosure, decodes digital data encoded by the encoder (-).

The present invention provides a membrane electrode assembly that enhances the reliability, mechanical strength, and handling characteristics of a seal in a solid polymer electrolyte fuel cell. The membrane electrode assembly of the present invention comprises a membrane-electrode structure having electrode layers and gas diffusion layers on both sides of a polymer electrolyte membrane, and a resin frame provided in such a manner as to fully enclose the outer periphery of the electrolyte membrane and to enclose at least portions of the outer peripheries of the gas diffusion layers, the resin frame being provided so as to enclose the electrolyte membrane side. The gas diffusion layer and electrode layer on one side are stacked on a surface of the electrolyte membrane so that a surface region of the electrolyte membrane is left exposed. The gas diffusion layer on the opposite side extends all around the outer periphery of the electrolyte membrane. The resin frame is attached fixedly to at least a portion to the surface region.

Provided is an instant black tea, which includes the non-polymer catechins at high concentration, is further reduced in bitterness and astringency, and is excellent in the appearance of its infusion. The instant black tea includes a beverage material containing black tea leaves and a dried green tea extract and sealed in a tea bag. A mass ratio of the non-polymer catechins/tannin in the beverage material is from 0.65 to 0.95.

A cleaning apparatus includes a handle for a cleaning cloth to be attached thereto, and a flat bag-like cleaning cloth having an insertion space therein. The handle is provided at a front end portion of a handle body with a head portion. The head portion is inserted into the insertion space, thereby attaching the cleaning cloth to the head portion. The cleaning cloth includes a joined portion formed by joining non-woven fabrics together and having a flat bag-like configuration defining an insertion space in the internal area of the cleaning cloth and a non-joined portion being provided at an external area of the joined portion.
