Abstract: There is provided an LED chuck comprising: a top plate on which an object to be inspected is mounted; an LED array substrate disposed to face the object to be inspected, and provided with a plurality of LEDs for heating the object to be inspected that is mounted on the top plate; a cooling plate disposed on a back side of the LED array substrate; an LED control substrate disposed on a back side of the cooling plate and controlling the plurality of LEDs; and a base plate disposed to surround the LED control substrate. A surface of the cooling plate facing the LED control substrate and a surface of the base plate facing the LED control substrate are formed of a magnetic material.

Abstract: Provided is a flexible printed circuit connection structure which includes a flexible printed circuit having a plurality of wires, a board to be connected having a plurality of wires to be connected, a plurality of solder connection portions, and a partition wall, in which: the plurality of solder connection portions is a part where the plurality of wires of the flexible printed circuit and the plurality of wires to be connected of the board to be connected are connected to each other by solder; the partition wall is provided away from the plurality of solder connection portions so as to surround the plurality of solder connection portions; and the flexible printed circuit, the board to be connected, and the partition wall define a sealed space, and the plurality of solder connection portions is arranged inside the sealed space.

Abstract: A disk rotor of a vehicle brake with improved efficiency in cooling the disk rotor by a synergy effect that comes from ensuring velocity of airflow flowing between cooling fins, ensuring surface areas of the cooling fins, and generating turbulent flow by second fins. A plurality of cooling fins each extending radially from an inner peripheral edge to an outer peripheral edge of a disk rotor are provided inside the disk rotor at intervals in the circumferential direction. Each of the plurality of the cooling fins includes a radial fin extending radially and a second fin spaced apart from the radial fin in the radial direction.

Abstract: According to a gaming machine of the present invention, when a specified internal win is determined based on a predetermined internal lottery table, an internal win is determined based on a specified internal lottery table having larger range of the random number determining the internal win of a replay than that of the predetermined internal lottery table. In addition, the internal win of the replay has higher priority than that of the specified internal win when the rotation of reel makes a stop.
