Patent number: 8031893Abstract: Supply of power is ensured on use without requiring troublesome works such as battery replacement work and charging work. Specifically, hearing aids, which collect sound, amplify the collected sound, and output the amplified sound, boosts electromotive force generated by the Peltier module derived from temperature difference between a human-body contact portion and an ambient-air contact portion, and causes sound collecting units, a controller IC, a speaker to operate by the boosted voltage.Type: GrantFiled: August 10, 2007Date of Patent: October 4, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Junji Imai, Hitoshi Makinaga, Hiroshi Inoue

Patent number: 7992445Abstract: In a pressure sensor including a pressure detecting element in an intermediate portion or at a deep side of a through hole formed in a protrusion, a body portion (a base portion and the protrusion) is made of ceramic or an insulative resin material and molded into a predetermined shape, and the pressure sensor is constituted as a molded interconnect device in which a conductive pattern is formed on a surface thereof. Accordingly, a smaller pressure sensor can be obtained.Type: GrantFiled: September 27, 2007Date of Patent: August 9, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Mitsuru Kobayashi, Hiroshi Inoue, Hitoshi Makinaga, Junji Imai, Yasufumi Masaki, Naoto Ikegawa, Youichiro Nakahara

Patent number: 7874503Abstract: An electrostatically atomizing device capable of instantly giving an electrostatically atomizing effect without requiring a water tank. The electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, a water feeder configured to give water on the emitter electrode, and a high voltage source configured to apply a high voltage across said emitter electrode and said opposed electrode to electrostatically charge the water on the emitter electrode for spraying charged minute water particles from a discharge end of the emitter electrode. The water feeder is configured to condense the water on the emitter electrode from within the surrounding air, enabling to supply the water on the emitter electrode in a short time without relying upon an additional water tank. Thus, an atomization of the charged minute water particles can be obtained immediately upon use of the device.Type: GrantFiled: April 1, 2005Date of Patent: January 25, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Osamu Imahori, Toshihisa Hirai, Kishiko Hirai, legal representative, Akihide Sugawa, Fumio Mihara, Shousuke Akisada, Tomoharu Watanabe, Hirokazu Yoshioka, Kentaro Kobayashi, Shinya Murase, Kouichi Hirai, Junji Imai

Patent number: 7804395Abstract: A mobile radio communication system estimates the positional relationship between an own moving terminal and another moving terminal around a view obstruction. If the absolute value of the difference between detected reception power levels is lower than a first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being shorter than a predetermined distance BP, or that the other moving terminal is positioned outside thereof, the distance to the visual range of the own moving terminal being shorter than the predetermined distance BP. Also if the absolute value is higher than or equal to the first power threshold value, the own moving terminal determines in a similar manner.Type: GrantFiled: March 19, 2008Date of Patent: September 28, 2010Assignee: Kabushiki Kaisha Toyota ChuoInventors: Junya Muramatsu, Satoshi Makido, Junji Imai, Kenji Ito, Yukihiro Tadokoro

Patent number: 6400013Abstract: A thermoelectric module is capable of successfully reducing the heat stress for increased reliability. The module includes a plurality of thermoelectric chips of P-type and N-type arranged in a matrix between sets of first and second contacts to form a series electrical circuit. The chips are arranged to give at least three chip arrays each having a limited number of the chips. A first carrier is provided on one side of the chips to carry the first contacts and to include first bridges each integrally joining two adjacent first contacts to define first discrete couples for electrical connection of the chips in each chip array. The first carrier further includes at least two inter-array bridges which are solely responsible for electrical interconnection between the adjacent chip arrays.Type: GrantFiled: November 13, 2000Date of Patent: June 4, 2002Assignee: Matsushita Electric Works, Ltd.Inventors: Michimasa Tsuzaki, Nobuteru Maekawa, Narimasa Iwamoto, Junji Imai, Hiroaki Okada, Teruaki Komatsu, Shinya Murase, Hiroyuki Inoue, Masayuki Sagawa, Yuri Sakai

Patent number: 6194088Abstract: An intermetallic-compound coated stainless steel having excellent rigidity, toughness, wear resistance and corrosion resistance comprises a substrate of a martensite stainless steel having a Vickers hardness of 400 or more, and a hard film having a bottom surface adhered to the substrate and an exposed top surface. The hard film has an outermost layer made of a compound selected from the group consisting of a Ti—Ni intermetallic compound, Ti—Fe intermetallic compound, and a mixture of the Ti—Ni intermetallic compound and a Ti—Cu intermetallic compound. The coated stainless steel can be produced by cladding an outer sheet made of Ti or a Ti alloy to a martensite stainless steel sheet directly or through an intermediate sheet made of Ni, Fe or a Ni—Cu alloy, heating the laminate at a temperature of 900° C. to 1150° C. for 30 seconds to 5 minutes, and then cooling the heated laminate at a cooling rate of 1° C./sec or more.Type: GrantFiled: July 1, 1999Date of Patent: February 27, 2001Assignees: Daido Steel Co., Ltd., Matsushita Electric Works, Ltd.Inventors: Hiroaki Yoshida, Hiroshi Yamada, Fumio Iwane, Junji Imai, Tadashi Hamada, Shinji Fujimoto, Shuji Yamada, Shigetoshi Sakon

Patent number: 5981089Abstract: A ferrous alloy is formed with a Fe--Cr stainless steel having a Vickers hardness of 400 or more as a substrate and a Fe--Al diffusion layer having a thickness of 2 to 50 .mu.m. The diffusion layer contains at least 90 vol % of an intermetallic compound of Al and Fe relative to a total volume of the diffusion layer. The Al content included within a depth of at least 2 .mu.m of the diffusion layer is 35 to 65% by weight based upon total weight of a region of the diffusion layer ranging up to the thickness of at least 2 .mu.m. It is preferred to use as the substrate a precipitation-hardening stainless steel comprising 66 to 81.9 wt % of Fe, 15 to 20 wt % of Cr, 3 to 13 wt % of Ni, and one element selected from 3 to 6 wt % of Cu, 0.5 to 2 wt % of Al, and 0.01 to 0.2 wt % of a total of C and N, or a high carbon stainless steel comprising 73 to 89.9 wt % of Fe, 10 to 19 wt % of Cr, 0.1 to 1.2 wt % of C, and less than 3 wt % of Ni.Type: GrantFiled: May 20, 1996Date of Patent: November 9, 1999Assignee: Matsushita Electric Works, Ltd.Inventors: Junji Imai, Tadashi Hamada, Shuji Yamada, Hiroshi Yamada, Fumio Iwane

Patent number: 5156805Abstract: A ferritic alloy with a wear resistive oxide scale is obtained through the steps of pressing a ferritic alloy powder containing aluminum into a powder compact of a desired configuration, sintering the powder compact in a non-oxidizing atmosphere to provide a resulting sintered product, and heat-treating the sintered product in an oxidizing gas atmosphere in order to precipitate in the surface thereof alumina in the form of an alumina scale as the wear resistive oxide scale which is responsible for improved surface hardness or wear resistance. Due to the inherent porous nature of the sintered product, the oxidizing gas can readily penetrate deep into the surface of sintered product to facilitate the oxidization of the product surface into the alumina scale, in addition to that the oxidization depth can be controlled such as by the density of the product, which makes it possible to readily control the thickness of the alumina scale.Type: GrantFiled: July 25, 1991Date of Patent: October 20, 1992Assignee: Matsushita Electric Works, Ltd.Inventors: Junji Imai, Shuji Yamada, Tadashi Hamada, Hajime Kojima, Masao Tanahashi
