Abstract: Provided is a laser processing device that enables a film to be stabilized and processed. The present invention comprises: a conveyance mechanism that conveys a film; a holding mechanism that has a pair of holding parts which can at least sandwich and hold lateral portions of the processing range of the film; and a laser mechanism for processing the processing range of the film held by the holding mechanism.

Abstract: An antenna device includes a printed circuit board including a circuit configured to determine a position based on a navigation signal, and a dipole antenna element mounted on the printed circuit board and configured to receive the navigation signal. Further, the antenna device includes an L-shaped parasitic antenna element, wherein the dipole antenna element and a long-side element of the L-shaped parasitic antenna element are placed parallel to each other but at a position not in line with each other, and an end of a short-side element of the L-shaped antenna element is placed in close proximity to an end of the dipole antenna element.

Abstract: A blower includes an impeller rotatable about a central axis, a motor that drives the impeller, and a housing that accommodates the impeller and the motor. The impeller includes a plurality of vanes arrayed in a circumferential direction and a flange in which the plurality of vanes are provided at an outer circumferential edge on a radially outer side. The housing includes a first housing that faces a vane lower end surface located on an axial-direction lower side of the vane with a gap interposed therebetween. The vane lower end surface includes a first vane end surface in which a shortest distance to the first housing in an axial direction increases toward the radially outer side.

Abstract: The blowing device includes an impeller that is rotatable about a center axis and a motor that drives the impeller. The impeller includes a plurality of vanes arranged in a circumferential direction, a flange in which the plurality of vanes are provided at the outer circumferential edge in a radial-direction outside, and a plate-shaped first shielding unit located between the vanes adjacent to each other in the circumferential direction. The first shielding unit is connected to a rear edge surface on an opposite side to the rotation direction of the vane and an outside surface located on the radial-direction outside of the flange.

Abstract: A blower apparatus includes an impeller arranged to be capable of rotating about a central axis extending in a vertical direction, and a motor arranged to drive the impeller. The impeller includes a plurality of blade portions arranged in a circumferential direction, and a flange portion arranged to have the blade portions arranged on an outer peripheral portion thereof on a radially outer side. At least one of the blade portions includes a shoulder portion at an end portion thereof on a radially inner side and on one axial side. The shoulder portion includes a first end surface arranged to face to the one axial side, a second end surface arranged to face to the one axial side and arranged on another axial side of the first end surface, and a third end surface arranged to join an inner end portion of the first end surface on the radially inner side and an outer end portion of the second end surface on the radially outer side to each other.

Abstract: A blower apparatus includes an impeller arranged to be capable of rotating about a central axis extending in a vertical direction, and a motor arranged to drive the impeller. The impeller includes a plurality of blade portions arranged in a circumferential direction, and a flange portion arranged to have the plurality of blade portions arranged on an outer peripheral portion thereof on a radially outer side. Each blade portion includes a trailing edge surface arranged on a rearward side of the blade portion with respect to a rotation direction of the impeller in the circumferential direction, and a leading edge surface arranged on a forward side of the blade portion with respect to the rotation direction in the circumferential direction. The trailing edge surface includes at least one recessed portion recessed forward with respect to the rotation direction.

Abstract: A blower includes an impeller that is rotatable about a vertically extending central axis; a motor that drives the impeller; and a housing that accommodates the impeller and the motor. The impeller includes a plurality of vanes and a flange in which the plurality of vanes are provided. The housing includes a first housing unit that faces a vane one end surface located on an axial-direction one side of the vane with a gap interposed therebetween. The first housing unit includes an inlet port penetrating in the axial direction. One end surface of the flange located on one side in the axial direction of the flange includes a first flange end surface located on an inside in the radial direction of one end surface of the flange and a second flange located on an outside in the radial direction with respect to the first flange end surface.
