Abstract: A fan includes an impeller including an impeller plate and a motor including a rotor with a rotor plate. A protrusion of the impeller plate protrudes downward in an axial direction from a lower surface on a lower side in the axial direction toward the rotor plate. A plate spring of the rotor plate extends in a direction intersecting the axial direction and is bendable in the axial direction. At least a portion of the protrusion is accommodated in a hole of the rotor plate. The protrusion contacts a leading end of the plate spring while being accommodated in the hole. The plate spring is bent in the axial direction while the protrusion is in contact with the leading end of the plate spring.

Abstract: A fan motor includes a stationary portion, a rotary portion, and an impeller. The rotary portion is configured to rotate about a center axis with respect to the stationary portion through a bearing mechanism. The impeller is configured to rotate together with the rotary portion. The stationary portion includes an armature including a coil positioned around the center axis, a metal base plate arranged below the armature, and a circuit board located above or below the base plate and provided with a lead wire electrically connected to the outside. The base plate and the lead wire are isolated from each other by a protection member. By installing the protection member between the metal base plate and the lead wire, the lead wire is prevented from making direct contact with the inner peripheral edge of the metal base plate.

Abstract: A laser processing machine includes a work head, a plate-like work working table for processing a plate-like work, a rod-like work working table including a rod-like work holder for processing a rod-like work, and a work area in which the work head is movably provided. The plate-like work working table is provided movably from one side of the work area into the work area. The rod-like work working table is provided movably from another side of the work area into the work area that is opposite side of the one side. According to the laser processing machine, when switching over between a processing of a plate-like work and a processing of a rod-like work, it is needed only to move/evacuate the plate-like work working table and the rod-like work working table to/from the work area, so that the switching-over operation can be easily done.

Abstract: A motor includes a cover made of a resin material. The cover includes a first annular portion arranged to extend in an annular shape above coils, a side wall portion arranged to extend downward from an outer circumferential portion of the first annular portion, and a second annular portion arranged to extend radially outward or radially inward from a lower end portion of the side wall portion along an upper surface of a circuit board. The side wall portion is arranged to extend in an axial direction while filling in gaps between teeth on a radially inner side of radially outer end surfaces of the teeth. The coils are covered by the cover to be protected from dust, water droplets, etc. The radially outer end surfaces of the teeth are exposed from the cover, and are thus arranged to be in radial proximity to a rotor magnet.

Abstract: A vehicle display having an LCD display that is employed to communicate a first type of vehicle information and a second set of vehicle information in which the information that is to be communicated can include or consist of symbols. A display light guide is employed to distribute light from two light sources to selectively illuminate portions of the display screen of the LCD display. The LCD display can be employed to generate telltale warning indicators. The LCD display provides flexibility in the display of information so that a relatively large quantity of telltale warning indicators can be handled without specifically dedicating a light source, a light tunnel and space on the vehicle display for each telltale warning indicator that may be employed in a vehicle.
