Patent number: 11308930Abstract: An electronic horn for use, e.g., in a vehicle, includes a piezoelectric element (52) that excites a plate-shaped oscillator (51). A resonator (7) is provided with an opening (71) and covers forward of the oscillator such that a resonance space (S) is defined between the resonator and the oscillator. An inner cylinder (62) and an outer conical housing (63) are provided concentrically around the resonator. A circular cover (8) covers the inner cylinder (62) and the outer conical housing (63) from the front, such that a buffer chamber (BR), at least one first sound amplifying chamber (MH1), and a second sound amplifying chamber (MH2) are defined around an entire circumference of the opening of the resonator.Type: GrantFiled: November 9, 2017Date of Patent: April 19, 2022Assignee: IMASEN ELECTRIC INDUSTRIAL CO., LTD.Inventors: Katsunori Uchimura, Koichi Toyama, Junjiro Yoshimura, Toshihiko Kawamura, Yoshio Miyata

Patent number: 11145286Abstract: An electronic horn includes a cover (8) on a front side of an intermediate element (6). A first passage (P1) within the horn is defined by a central portion (82) of the cover (8) that projects into a cylindrical interior of a cylindrical water-proofing wall (621). Second passages (P2, P3, P4) extend generally concentrically with respect to the first passage (P1) and are respectively defined by water-proofing walls (83, 84) that are formed on the cover (8) and project into the interior spaces of water-proofing walls (622, 633). The outermost second passage (P4) opens toward the forward direction. The first and second passages (P1-P4) extend in a back-and-forth path that prevents any rainwater, which has entered the interior of the horn through the opening of the outermost second passage (P4), from reaching a resonance space (7) defined between the resonator (7) and a sound-generating oscillator (51).Type: GrantFiled: February 23, 2018Date of Patent: October 12, 2021Assignee: IMASEN ELECTRIC INDUSTRIAL CO., LTD.Inventors: Katsunori Uchimura, Koichi Toyama, Yoshio Miyata, Tetsuo Momo, Toshihiko Kawamura, Junjiro Yoshimura

Patent number: 8978411Abstract: An outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.Type: GrantFiled: May 27, 2010Date of Patent: March 17, 2015Assignee: Denso CorporationInventors: Atsushi Yamada, Seiji Inoue, Yoshio Miyata, Naoki Yokoyama, Etsuo Hasegawa, Jun Abei, Hiroshi Ishikawa, Aun Ota, Kouta Hagihara
