Abstract: A circuit device includes a pre-driver that drives a gate of a first N-type MOS transistor provided between a power supply node and a switch node, and a bootstrap circuit that generates a boot voltage of the pre-driver from a power supply voltage. A boot capacitor is provided between the switch node and a boot node that supplies a boot voltage to the pre-driver. The bootstrap circuit includes a P-type MOS transistor provided between the power supply node and the boot node, and a Schottky barrier diode. The Schottky barrier diode has an anode coupled to the power supply node and a cathode coupled to the boot node.

Abstract: An exhaust structure for a straddle-type vehicle includes a muffler having an outer tube constituting an outer circumferential member of the muffler; first and second separators defining expansion chambers in the outer tube; a body end member arranged at the downstream end of the outer tube; and glass wool provided on the inner circumference of the outer tube. The muffler further includes a resonator chamber provided in the most downstream portion of the muffler. The resonator chamber is formed by the outer tube, the body end member and the second separator situated closest to the body end member. The surroundings of the resonator chamber are surrounded by the glass wool. Such exhaust structure of a straddle-type vehicle is capable of taking measures against exhaust heat and exhaust sound even with a configuration where there is only one, single resonator chamber.

Abstract: A tapping tool is mountable on an adapter for tapping. The adapter includes a ring gear in which the tapping tool is mountable; and a gear holder in which the ring gear is disposed and which is mountable on a turret of a turret punch press so as to locate the disposed ring gear at a position corresponding to a punch mounting section formed in advance in the turret. The tapping tool includes a cylindrical body and a rotating body.
