    摘要: A method of manufacturing a fan guard from a plate member wherein inward slits, each having at least a radial slit section are formed in a first section of the plate member located between a central section and a ring-like section radially outwardly spaced therefrom of the plate member such that the radial slit sections extend from the central section to the ring-like section in circumferentially spaced relation to each other. Radially outward slits, each having at least an arcuate slit section, are formed in a second section of the plate member located between the ring-like section and an outer peripheral section of the plate member such that the arcuate slit sections extend from the ring-like section to the outer peripheral section in circumferentially spaced relation to other. Portions each extending between the adjacent two radial slit sections are bent to form louvers. The central, first and ring-like sections are offset from the outer peripheral section while rotating the central, first and ring-like sections relative to the outer peripheral section, to twist portions extending between the adjacent two arcuate slit sections to form louvers.

    摘要: A method of magnetizing a rotor of a motor including the rotor made of an integrated magnet member and a stator is provided. Predetermined magnetic fields are preliminarily applied to the rotor to form magnetic paths and thereafter, the rotor is demagnetized. Then, the rotor is assembled into the stator. The rotor and stator are positioned such that the directions of the magnetic fields which are generated from the stator winding of the stator coincide with the directions of the magnetic paths of the rotor. Subsequently, in the state in which both of the rotor and stator are positioned, a current is supplied to the stator winding and the magnetic fields are generated, thereby magnetizing the rotor by the magnetic fields.

    摘要: A refrigeration evaporator includes a serpentine refrigerant tube having a plurality of finned straight portions connected by unfinned U-shaped connecting portions to form a stacked assembly of side-by-side finned tube arrays. The fins are rectangular and are provided with a J-shaped cut-out at each corner. The J-shaped cut-outs at confronting corners of the fins of each immediately adjacent pair of finned tube arrays define a U-shaped heater receiving space extending the length of the arrays and which clampingly receives an elongated straight portion of a serpentine electric defroster heater in good heat conductive contact with each fin of the immediately adjacent pair of finned tube arrays. Each fin of the stacked assembly has at least two corners in engagement with the heater. The stacked assembly is disposed transversely in a duct having an air inlet and air outlet. The fins nearest the inlet are spaced at a larger interval than those nearest the air outlet to preclude air flow restriction due to greater frost formation on the fins immediately adjacent the inlet.
