Abstract: A heart rate of a user is monitored by a heart rate sensor set. On a touch panel, during execution of high-load exercise, time required from the start of the high-load exercise until the heart rate rises to reach a threshold of a lower limit of a target heartbeat zone of the high-load exercise is measured as a first threshold reaching time and displayed in a threshold-reaching-time display section. During execution of the following low-load exercise, time required from the start of the load exercise until the heart rate falls to reach a threshold of an upper limit of a target heartbeat zone of the low-load exercise is measured as a second threshold reaching time and displayed in the threshold-reaching-time display section.

Abstract: A running watch includes: a time measurement portion which measures a lapse of time; an operation button which indicates a measurement with respect to the time measurement portion; a display portion which displays a measurement result in the time measurement portion on a display screen; and a display color switching portion which switches a display color of the display screen corresponding to a measurement state of the time measurement portion.

Abstract: A wireless communication apparatus includes a transmitter circuit whose transmission power is set variably, a wireless communication section having a receiver circuit, and a processing section that executes a control of the wireless communication section. The processing section sets the transmission power of the transmitter circuit to a first transmission power when it executes normal data communication and sets the transmission power of the transmitter circuit to a second transmission power smaller than the first transmission power when it executes a pairing process.

Abstract: A nozzle surface cleaning apparatus is configured to clean a nozzle surface of a droplet ejection head in which the nozzle surface is inclined with respect to a horizontal plane. The nozzle surface cleaning apparatus includes: a cleaning liquid deposition device which deposits cleaning liquid on the nozzle surface while moving relatively to the nozzle surface in a direction perpendicular to a direction of inclination of the nozzle surface; and an excess cleaning liquid removal device which removes excess cleaning liquid adhering to a lower edge portion of the nozzle surface in terms of the direction of inclination, while moving relatively to the nozzle surface in the direction perpendicular to the direction of inclination of the nozzle surface, the excess cleaning liquid being a part of the cleaning liquid deposited by the cleaning liquid deposition device.
