Abstract: Provided is a method for charging, with ceramic, open pores formed in a matrix of a ceramic matrix composite that includes the matrix and reinforcing fibers provided in the matrix. The ceramic comes to constitute the matrix. The method includes repeating the following steps (A) and (B) in a state where the ceramic matrix composite is arranged in a liquid material serving as a matrix material. At the step (A), the ceramic matrix composite is heated such that the liquid material is brought into a film-boiling state, and the ceramic derived from the liquid material is thereby generated in the open pores. At the step (B), the ceramic matrix composite is cooled until a temperature of the ceramic matrix composite becomes lower than a boiling point of the liquid material.

Abstract: A VTOL aircraft (moving object) includes: a first communication path allowing a cabin (passenger compartment) and a component compartment to communicate with each other; and a second communication path for opening the component compartment to the outside of a fuselage. A portion of air in the cabin flows through a first circulation path and returns to the cabin, and the remaining air in the cabin flows through the first communication path and is introduced into the component compartment. A portion of air in the component compartment flows through a second circulation path and returns to the component compartment, and the remaining air in the component compartment flows through the second communication path and is discharged to the outside of the fuselage.

Abstract: Provided are a display method and a display device with which the display performance of a two-dimensional code can be improved in a display panel that can be used without damaging the texture of a space. When a display fault occurs in a display panel in which a thin layer, comprising a naturally-derived wood, a natural fiber, a natural leather, or a natural stone, or comprising a synthetic fiber, a synthetic leather, or a synthetic stone that is a raw material produced by imitating a natural appearance and feel, is provided on the peripheral surface of a housing so as to be in contact with the panel front surface, a two-dimensional code is corrected by being moved or rotated and is displayed.

Abstract: A single-acting hydraulic cylinder includes a cylinder head provided in the opening of the cylinder tube to allow the piston rod to be inserted, a bushing provided on an inner circumference of the cylinder head to slidably support the piston rod, and a housing recessed portion formed on the inner circumference of the cylinder head to receive the bushing forcibly inserted from the inlet portion. A bottom clearance filled with the grease is formed between the bottom face of the housing recessed portion and the bushing.

Abstract: A sheet processing apparatus is provided with an operation member and an motion member that rotates with a force of the operation member through the connection part and applies force to an acting member. A fulcrum of a rotating operation of the operation member moves depending on an operation of the operation member. A first length between the fulcrum and a part at which the operation member is applied with the force and a second length between the fulcrum and a part at which the force is applied from the operation member to the motion member are changed.

Abstract: In a cylinder control device comprising a control valve that controls a flow of working fluid flowing between a cylinder and a pump, the control valve includes a spool provided in a main body portion, a sleeve that is provided in the main body portion opposite each of two end portions of the spool, and includes a communicating port that communicates with a valve chamber, a communicating passage that communicates with a cylinder chamber, and a throttle passage that communicates with the cylinder chamber, a valve body provided in the sleeve to control a communication state between the communicating port and the communicating passage and throttle passage in accordance with a sliding position thereof, and a biasing member that biases the valve body in a valve closing direction.

Abstract: A clincher unit is provided with a pair of clinchers for bending two legs of a staple; and a clincher driving mechanism for rotating and moving the clinchers in separating/contacting directions. The clincher driving mechanism moves the pair of clinchers in an approaching direction each other, as a movement of starting to bend the legs of the staple having penetrated the sheets.
