Abstract: A light emitting element of one or more embodiments includes a first electrode, a second electrode oppositely to the first electrode, and an emission layer between the first electrode and the second electrode. The light emitting element of one or more embodiments includes a polycyclic compound represented by a specific chemical structure in the emission layer, thereby showing improved emission efficiency and life characteristics.

Abstract: An outer peripheral cutting edge located on a rear side in a rotation axis direction of the inclined cutting edge, a rotation diameter of the base metal on the rear side in the rotation axis direction of the outer peripheral cutting edge is smaller than a rotation diameter of the outer peripheral cutting edge, in a cross section perpendicular to a direction in which the inclined cutting edge extends, a cutting edge ridge of the inclined cutting edge has a roundness of a radius less than or equal to 30 ?m, and a maximum height difference value of the cutting edge ridge of the inclined cutting edge is less than or equal to 20 ?m.

Abstract: A game machine determines the reference timing included in a predetermined time range and the crossing direction position corresponding to the reference timing based on the sequence data (30). And, the game machine causes an instruction path (R) extending from one end side (UP) in depth direction (TD) toward the other end side (DP) while passing through each crossing direction position corresponding to each reference timing at a position on the time axis corresponding to each reference timing and the reference line (TL), to be displayed on the game screen, and decreases a distance between each position and the reference line (TL) with a decrease in a time difference between the reference timing and the current time.

Abstract: A game machine includes: a monitor (2) that displays and outputs a game screen (40R); a control panel (3) that includes volume controllers (9) operated so as to change a position of an outer circumferential portion (SP) of a knob portion (9T); a external storage device (20) that stores sequence data (30) in which a reference timing at which the volume controllers (9) are operated during a game is associated with a reference position at which the outer circumferential portion (SP) is to be positioned at the reference timing. And, the game machine teaches information of the reference timing and the reference position to a player, based on the sequence data (30).
