A manufacturing method for a mower cord and including pressing a resin wire rod and plastically deforming at least part of the wire rod in an axis perpendicular direction. Work-hardening of a surface of the plastically deformed portion allows dramatic enhancement of mowing efficiency.

Mower cord and manufacturing method for mower cord

The present invention relates to a manufacturing method for a mower cord and includes pressing a resin wire rod and plastically deforming at least part of the wire rod in an axis perpendicular direction. Work-hardening of a surface of the plastically deformed portion allows dramatic enhancement of mowing efficiency.

Provided is a projection apparatus that can enhance the efficiency of utilization of RGB laser lights, eliminate positional displacement in projection point caused by spaced-apart fiber cores emitting the laser lights, and detect additional information while projecting an image with the laser lights. The projection apparatus includes a laser light source emitting infrared and RGB laser lights, a fixing device fixing end portions of an infrared-light fiber and colored-light fibers used to transmit the infrared and RGB laser lights, a scanning unit projecting an image on a projection surface by scanning the projection surface with the RGB laser lights emitted from the end portions of the colored-light fibers, a detection unit detecting reflection of the infrared laser light emitted from the end portion of the infrared-light fiber, and a control unit controlling emission of the RGB laser lights from the light source, based on information detected by the detection unit.

Laser projection apparatus with bundled fibers

The present invention is directed to the provision of an information input apparatus that can change the projection position of an input image by tracking a target object and can detect an information input to the input image. More specifically, the invention provides an information input apparatus includes a projection unit which projects an input image, a projection position changing unit which changes the projection position of the input image, a detection sensor which detects the position of a detection target, and an information detection unit which causes the projection position changing unit to change the projection position of the input image by tracking the position of the detection target detected by the detection sensor, and which detects an information input to the input image based on data supplied from the detection sensor.
