Patent number: 5743103Abstract: An air conditioner is provided and includes a louver which is provided at a blowing opening. The louver is moved rotationally from above to below or from below to above by a variable speed mechanism. At the time of heating, a louver rotational speed while the louver is moved rotationally in a range of a blowing angle .theta..sub.1 is set to a speed .omega..sub.1 within a vortices generation area relative to a wind velocity of blowing air flow. Also, a louver rotational speed while the louver is moved rotationally over the blowing angle .theta..sub.1 is set to a speed .omega..sub.1 within a vortices non-generation area relative to the wind velocity of blowing air flow. Thereby, at the time of heating, downward reach of warm air in a room while the louver is moved rotationally below the predetermined blowing angle and a temperature diffusibility while the louver is moved rotationally above the predetermined blowing angle are improved.Type: GrantFiled: September 27, 1996Date of Patent: April 28, 1998Assignee: Mitsubishi Jokogyo Kabushiki KaishaInventors: Masami Taniguchi, Fumio Kondoh, Hironari Fujiki, Kenichi Miyazawa, Masahiko Takahashi

Patent number: 4955424Abstract: A die-casting method in which a lubricant is heated to a temperature higher than a temperature of mold cavity surfaces before molten metal is injected into the mold cavity. The lubricant is heated when the mold cavity is formed by bringing a movable mold into contact with a stationary mold. The heated lubricant is introduced into the mold cavity and applied on the mold cavity surfaces, and the molten metal is then injected into the mold cavity. The molten metal is allowed to solidify in the mold cavity to become a solidified article. A die-casting device for carrying out this method is also provided according to the present invention.Type: GrantFiled: August 9, 1989Date of Patent: September 11, 1990Assignee: Nippondenso Co., Ltd.Inventors: Fumitaka Takehisa, Fumio Kondoh, Mitsuyoshi Yokoi

Patent number: 4949775Abstract: A die-casting arrangement which prevents a lubricant from becoming mixed into a die cast article which might cause it to bulge when later heated. The lubricating agent is sprayed over a high-temperature portion of a sprue interconnecting a mold cavity and an injection sleeve in order to partly carbonize the lubricant. The carbonized lubricating agent even if mixed into a die cast article will not expand even when the article is heated thereby preventing bulging of the article.Type: GrantFiled: September 7, 1989Date of Patent: August 21, 1990Assignee: Nippondenso Co., Ltd.Inventors: Fumitaka Takehisa, Mitsuyoshi Yokoi, Fumio Kondoh
