Patent number: 7373783Abstract: To provide an air conditioner capable of operating devices in an outdoor unit by connecting an indoor unit, which is capable of transmitting operational commands and operational modes using simple ON/OFF signals to the outdoor unit, even if the indoor unit does not have transmission means for transmitting and receiving information between the outdoor unit, or the indoor unit has transmission means with a different data transmission protocol from the outdoor unit. When it is determined that only ON/OFF signals of operational commands and operation modes have been transmitted, the devices disposed inside the outdoor unit are independently controlled based on the ON/OFF signals.Type: GrantFiled: December 14, 2004Date of Patent: May 20, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Osamu Kanaya

Patent number: 6224937Abstract: The invention aims at providing highly reliable zinc oxide varistors through simple production steps. The varistor is produced by dispersing a powdery raw material comprising 1-40 solar % (in terms of Fe2O3) iron, 0-20 molar % (in terms of Bi2O3) bismuth, and the balance consisting of SiO2 in a solution of a water-soluble binder such as polyvinyl alcohol, and applying the formed dispersion to a molded or calcined zinc oxide varistor to form on the lateral face thereof a lateral high-resistance layer (2) containing Zn2SiO4 as the principal ingredient and a solid solution of iron in Zn7Sb2O12 as the auxiliary ingredient.Type: GrantFiled: June 21, 1999Date of Patent: May 1, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaaki Katsumata, Osamu Kanaya

Patent number: 6041853Abstract: The present invention aims at obtaining a ceiling built-in type air conditioner in which noise attributable to the breakaway flow of air at the front ends of the fins is decreased. For this purpose, the ceiling built-in type air conditioner has a heat exchanger 4 installed within a main body cabinet 1 having an air suction inlet 2 and an air blowing outlet 3 and has a centrifugal blower 7 installed in the air suction inlet 2. In this ceiling built-in type air conditioner, a flat-plate-shaped rectifying member 9 is placed near the middle point between the center of the air suction inlet 2 and the center of the heat exchanger 4 and is placed substantially at a right angle to the direction of the flow of air from the air suction inlet 2.Type: GrantFiled: June 30, 1998Date of Patent: March 28, 2000Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Atsushi Edayoshi, Hiroshi Nakashima, Osamu Kanaya, Ryo Oya, Eiji Fukushima
