A laser marker in one aspect of the present disclosure includes a support body, a rotation body, a motor, a laser beam emitter, a device communicator, and a motor control circuit. The device communicator performs a wireless communication with a portable terminal device and with a beam receiving device. The portable terminal device transmits a rotation start command signal. The beam receiving device generates and transmits a bean receiving position signal. The motor control circuit starts controlling a rotation of the motor based on the beam receiving position signal in response to the device communicator receiving or having received the rotation start command signal.

Laser marker and portable terminal device

A laser marker according to one aspect of the present disclosure includes: a laser emitter; an information reception circuit; a measuring circuit; and a disabling circuit. The measuring circuit starts to measure an elapsed time in response to the information reception circuit receiving an enabled time. The disabling circuit disables the laser marker for operating in response to a length of the elapsed time reaching or having reached a length of the enabled time.

Technique for setting laser marker inoperable

A display control method in one aspect of the present disclosure includes: displaying a position image; acquiring a relevant signal; and rotating the position image. Displaying a position image includes displaying a position image in a specified direction with respect to a background image of a screen of a portable terminal device. Rotating the position image includes rotating the position image with respect to the background image so that an image direction matches a device direction.

Technique for providing notification of receiving position of laser beam emitted from laser marker

A backpack-type assembly may include: a body; and a base member. The body may include a cooling fan. The base member may include: a back plate attached to the body; and a harness attached to the back plate and configured to be worn on a user. The harness may include: a cooling port; and at least one shoulder belt configured to be worn on a shoulder of the user. The cooling fan may be configured to circulate cooling air into or out of the base member through the cooling port of the harness.

A laser marking system in one aspect of the present disclosure includes a laser marker, a beam receiving device, and a notifier. The laser marker includes a laser beam emitter. The beam receiving device includes a beam receiver and a transmitter. The beam receiver receives a laser beam emitted by the laser beam emitter. The transmitter transmits a first positional signal. The first positional signal indicates a receiving position of the laser beam in the beam receiver. The notifier notifies of the receiving position of the laser beam based on the first positional signal.

Laser marking system and portable terminal device

A fan switch and an ignition switch are arranged such that the moving directions of operating buttons thereof cross the moving directions of a contact lever and the moving direction of a switch lever, respectively.

Combustion type driving tools

A technique for improving the cooling performance of a combustion chamber in a combustion power tool is provided. The combustion power tool includes first and second combustion chambers, a partition that separates the first combustion chamber from the second combustion chamber, openings, formed in the partition and communicate the first combustion chamber with the second combustion chamber, and a drive section that moves toward a front end by combustion pressure. The combustion pressure is generated when a flow of flammable gas, which is produced by combustion of the flammable gas in the first combustion chamber propagates to the second combustion chamber through the openings, and burns flammable gas in the second combustion chamber. The combustion gas flows from the first combustion chamber to the second combustion chamber in a direction around a central axis of the second combustion chamber while flowing along an inner wall of the second combustion chamber.
