  • Patent number: 11204571
    Abstract: A heating apparatus to heat an image borne on a recording material includes a heater having a heater portion with first and second heating elements, where the heating elements have different lengths and resistance values. The heating apparatus also includes a power source, a switching unit, a control unit, and a voltage detection unit. The power source supplies power to the heating elements. The control unit controls the switching unit two switch a connection between the power source and the first heating element and the second heating element. The voltage detection unit detects an input voltage input from the power source to the heating elements. The control unit switches a power ratio, which is a ratio between an electric energy supplied from the power source to the first heating element and an electric energy supplied from the power source to the second heating element, depending on the detected input voltage.

  • Patent number: 10283264
    Abstract: In a method of manufacturing a laminated core, a laminated core body 14 including magnet insertion holes 12 and 13 with magnet pieces 15 inserted therein is placed between a molding (upper) die 10 and a retaining (lower) die 11, and a molding resin 19 is filled from resin reservoir portions (pots) 16 to fix the pieces 15 in the holes 12 and 13. Between the die 10 and the body 14, a guide member 18 is placed, which includes resin passages 31 provided from the portions 16 to the holes 12 and 13 and gates 30 connecting to the holes 12 and 13 on downstream sides of the passages 31. The method can reduce lead time of a production line without replacing the molding dies for different laminated rotor cores and thus without preparing different types of molding dies.

  • Patent number: 10184379
    Abstract: A particulate filter for trapping the particulate matter which is contained in the exhaust gas is provided inside an engine exhaust passage. Additional fuel is secondarily injected from a fuel injector in an engine expansion stroke or exhaust stroke or hydrocarbons are secondarily added from an addition valve which is provided upstream of the particulate filter in the exhaust pipe. An amount of hydrocarbons which come from the fuel injector or addition valve and then adhere in the form of a liquid to the inflow end of the particulate filter, and an amount of particulate matter which reaches the inflow end of the particulate filter are respectively estimated. A degree of clogging at the inflow end of the particulate filter is estimated based on the amount of hydrocarbons and the amount of particulate matter.
