An air circulator includes a blower unit having an airflow opening on a front side of the blower unit and a grill in the airflow opening, and a support unit that supports the blower unit. The grill has a plurality of airflow guide blades arranged in a spiral, and inner end portions of the airflow guide blades proximal to a center of the spiral of the plurality of airflow guide blades protrude from outer end portions of the airflow guide blades in an airflow direction. The blower unit includes a cover forming an outer panel of the blower unit and an air passage forming member provided inside the cover. A reinforcing rib is formed on an outer circumferential surface of the air passage forming member.

Air circulator

An air circulator includes a blower unit that is provided with an airflow opening on a front side of the blower unit. A grill is provided in the airflow opening, and is provided with airflow guide blades in a spiral manner. The air circulator also includes a controller that achieves a rhythm air in which weak wind and strong wind are switched over by controlling a rotational speed of a motor of the blower unit. The grill is provided with plural airflow guide blades in a spiral manner. Inner end portions of the airflow guide blades closer to the center of the spiral of the airflow guide blades are protruded from outer end portions if the airflow guide blades in an airflow direction.

This heat-caulking device is inserted into one or more holes penetrating a main plate having a substantially conical hollow portion, whereby one or more bosses of a blade protruding from an inner peripheral surface of the main plate toward the hollow portion are melted so as to join the main plate and the blade. A heat chip of the heat-caulking device has a substantially conical hollow main body portion, an outer peripheral surface of which conforms to the inner peripheral surface of the main plate. On the outer peripheral surface of the main body portion, a convex portion protruding toward the vicinity of the holes of the inner peripheral surface of the main plate is provided.

Heat-caulking device

Provided is a thermal caulking method of melting, at one time, a plurality of bossesof a second memberprotruding toward an inner circumferential surface of a conical hollow portionof a first memberwhile being fitted to a plurality of holesprovided in the inner circumferential surface of the hollow portionof the first memberhaving the substantially conical hollow portionso that the plurality of bosses are joined to the first member, in which the plurality of bossesare melted at one time by using a heat chiphaving a continuous shape in the circumferential direction of the hollow portionalong the inner circumferential surface and are joined to the first memberwhile the adjacent melted bossesare connected to each other.

Thermal caulking method, thermal caulking device, and caulked material

An impeller in which blades and a shroud are bonded in a stable manner. The impeller is provided with a plurality of blades disposed on a base, and a shroud disposed facing the base across the blades. The shroud has a curved shape, wherein the shroud has a flat part in the outer periphery, protuberances are provided to flat surfaces of the blades, through-holes are provided to the flat part of the shroud, and, after the protuberances are inserted through the through-holes, the flat surfaces of the blades and the flat part of the shroud are bonded together by deforming the tips of the protuberances into thermally caulked parts larger in diameter than the opening diameters of the through-holes.

Impeller

Provided is a method for manufacturing an impeller composed of a frustum-shaped hub () and a plurality of blades provided on a peripheral surface () of the hub () at predetermined intervals in a circumferential direction and inclined in one direction. The method for manufacturing the impeller comprises: an injection-molding step of injection-molding a molding article () in which the blades are connected to the periphery of the hub () via fragile connection parts () so as to spread outward; a blade rotationally moving step of rotationally moving the blades () to the peripheral surface () of the hub () about the connection parts (); and a fixation step of fixing ends of the blades () to the hub ().

Method for manufacturing impeller

The first electrode section () and the second electrode section () are formed such that the outer portion connected to the upper portion of the heating section () is thinner than the inner portion connected to the lower portion of the heating section (). The heating section () and the first electrode section () are interconnected by an R-shaped first connecting portion (). The inner circumferential sloping surface of the heating section () and the second electrode section () are interconnected by an R-shaped second connecting portion (). The first and second connecting portions ()() are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion () is smaller than the thicknesses of the first and second connecting portions ()().

Thermal caulking device

An impeller in which a plurality of vanes are provided so as to overlap each other back and forth as viewed in the direction of axis has a first impeller part on a front side and a second impeller part on a rear side. A method for manufacturing impeller includes a step of molding a first impeller part, a step of molding a second impeller part and a step of combining together the first impeller part and the second impeller part.

The present invention provides a disinfectant that contains olanexidine in a concentration sufficient to exhibit an effective bactericidal effect, and that has hardly any side effects such as skin irritation. Specifically, the present invention provides a disinfectant containing an aqueous solution that contains olanexidine and at least an equimolar amount of gluconic acid, and substantially contains neither an acid other than gluconic acid nor a salt of the acid other than gluconic acid.
