Patent number: 9295110Abstract: An inductive heating device is structured such that a coil base and ferrites placed under a heating coil in the vertical direction are flushed with each other at their lower surfaces and are directly placed on a heat dissipation plate. A heat conductive member is charged between the ferrites and an electrical insulating member sandwiched between the heating coil and the ferrites, at least at a portion thereof, so that thickness variations in the ferrites are absorbed thereby, which realizes a state where they are thermally coupled to each other from the heating coil to the heat dissipation plate.Type: GrantFiled: October 21, 2010Date of Patent: March 22, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Eiji Matsui, Akira Kataoka, Takehiko Shigeoka

Patent number: 9241374Abstract: To reduce the air exhausted to outside a main body after cooling a heat generating component from being taken in again from an intake port. The flow of cooling wind cooled the heat generating component is discharged from an exhaust port at other than a first peripheral wall with the flow bent inside the main body. When rectified inside the main body and discharged from the exhaust port, the cooling wind grows to a flow speed of a certain extent to become an exhaust air that a flowing direction is clearly defined, so that it is less likely to be taken in again from the intake port, it is less likely to be subjected to the influence of obstacles of the exhaust port, use can be made in a kitchen cabinet of the intake and exhaust air at the back side, and it is satisfactory and is less likely to be damaged without involving sense of unpleasantness by the exhaust air to the user.Type: GrantFiled: March 14, 2011Date of Patent: January 19, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Eiji Matsui, Akira Kataoka, Takehiko Shigeoka, Takaaki Kusaka, Kenji Ogawa

Patent number: 8418566Abstract: An objective of the invention is to provide a multilayered flow passage member that enhances fluid measurement accuracy of an ultrasonic fluid measurement apparatus and an ultrasonic fluid measurement apparatus using the multilayered flow passage member. When fusible projections 20 are fused by a heating head 21 while partition plates 11 are inserted into side plates 13 and 14, a fused state provided by the heating head 21 changes according to either side of each of the partition plates 11, because fuse surfaces at leading ends of the respective fusible projections 20 are sloped in the vertical direction. An outermost end of each of fusible projections 25 that first contacts the heating head 21 is first fused. During a course of the fusible projections 25 being fused toward their roots, the partition plates 11 are pressed against ends of respective insert holes 17a that are on the opposite side of the outermost ends that are first fused.Type: GrantFiled: November 5, 2009Date of Patent: April 16, 2013Assignee: Panasonic CorporationInventors: Hirokazu Gotou, Takehiko Shigeoka
