  • Patent number: 11418684
    Abstract: Matching timings of transmitting pieces of information for reproducing video and audio with presence and handling loss are provided. An information synchronization device is configured to synchronize, to a reference timestamp, data in which one or more labels for identifying respective one or more subjects on a video and one or more pieces of location information for identifying respective locations of the one or more subjects are respectively associated. The information synchronization device includes a reception unit for receiving the data at each time, a buffer for storing the received data, and a location information interpolation unit for generating, when pieces of the location information at times before and after the reference timestamp is stored into the buffer for any of the labels, location information of the label at the reference timestamp by interpolation using the pieces of the location information.

  • Patent number: 10895385
    Abstract: Cooking apparatus (10) includes heating chamber (4) in which an object to be heated is rested, radiant heater unit (38) provided inside heating chamber (4) and operating in the preheating mode and cooking mode, and a control unit controlling radiant heater unit (38). The control unit is configured to make radiant heater unit (38) operate in the standby mode, which is a mode after the preheating mode ends and until the cooking mode starts. According to this aspect, the surface temperature of radiant heater unit (38) is kept at a high level during the standby mode to suppress uneven browning due to variations in the surface temperature of radiant heater unit (38) when cooking starts.

  • Patent number: 10362641
    Abstract: A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.

  • Publication number: 20160353529
    Abstract: Microwave oven (20) includes waveguide (3) having an E-bend structure, and multiple openings (4a, 4b). Waveguide (3) has first section (3a) for propagating a microwave from magnetron (2) toward heating chamber (1), and second section (3b) of which wide plane abuts on the outer wall of heating chamber (1). Multiple openings (4a, 4b) are disposed on a lateral face of heating chamber (1). Openings (4a, 4b) allow waveguide (3) to communicate with heating chamber (1), and include at least one circularly-polarized-wave opening (4a) for generating a circularly polarized wave. A cross section of first section (3a) orthogonally intersecting tube axis (7a) of first section (3a) is projected virtually along tube axis (7a) of first section (3a) onto a lateral face of heating chamber (1), and circularly-polarized-wave opening (4a) is formed such that its center is located outside the resultant projected region defined by this projection.

  • Patent number: 6906301
    Abstract: A high-frequency heating apparatus includes a magnetron (1), a magnetron holding plate (2), a waveguide (3), a heating chamber (4), and screws (5), and the magnetron (1) is attached to the magnetron holding plate (2) with two screws. Hereby, attachment of the magnetron is facilitated, speed-up of the manufacturing process of the high-frequency heating apparatus can be realized, and production efficiency can be improved. Further, in the breakdown repair requiring exchange of the magnetron, working time can be also reduced, so that service to customers can be also improved.

  • Patent number: 6870146
    Abstract: A high-frequency heating apparatus includes an outer enclosure, a high voltage generator such as a high-voltage capacitor, and an air guide, wherein the air guide is provided with a plastic hinge formed by partially reducing a wall thickness thereof. The invented structure can bend the plastic hinge to locate an end flap of air guide in a space between a terminal of the high-voltage capacitor and the outer enclosure defining a dead metal part, to easily ensure electrical insulation between the terminal and the outer enclosure without dependent on variations in quality of workmanship in the manufacturing process. In addition, it can reduce a number of working processes as well as amount of waste since all it requires is to bend the plastic hinge to provide the electrical insulation.

  • Patent number: 6864471
    Abstract: A plurality of slots are provided so as to be located between a thin plate flexible opening section screen member and a heating chamber wall surface 1 for allowing insertion of the opening section screen member. A gently-curved bulging surface exists in an area where the heating chamber wall surface 1 and the opening section screen member 5 are mated together. As a result, residual warpage which would otherwise remain when the opening section screen member is warped for attachment becomes invisible, thereby preventing occurrence of clearance, which would cause sparking or the like.
