Patent number: 9024714Abstract: A static apparatus includes an iron core which includes a plurality of magnetic plates stacked in one direction and in which a shaft portion having a main surface and a side surface is formed, and a coil wound around the shaft portion. Slits extending in an axial direction of the shaft portion are formed in at least a surface layer magnetic plate constituting the main surface, of the plurality of magnetic plates. Some of the slits are formed in the main surface, at an end portion close to the side surface, at a predetermined formation density. The formation density of the slits is highest at the predetermined formation density, and is reduced as at least one of a minimum distance from the side surface within the main surface and a distance from the main surface on a side close to the slits in the stacking direction is increased.Type: GrantFiled: October 22, 2010Date of Patent: May 5, 2015Assignee: Mitsubishi Electric CorporationInventors: Tetsuya Matsuda, Ryuichi Nishiura, Hiroyuki Akita, Takeshi Imura, Yasuo Fujiwara, Yoshinori Shimizu, Kazuaki Aono

Patent number: 8872614Abstract: A transformer includes a leg iron core including a plurality of magnetic sheets stacked in one direction (Z axis direction), and a coil wound around the leg iron core. A slit is formed in at least a magnetic sheet which faces an inner peripheral surface of the coil in a stacking direction of the plurality of magnetic sheets, of the plurality of magnetic sheets. Since eddy current is divided by the slit, eddy current density can be reduced. By reducing the eddy current density, loss density in an iron core can be reduced. By reducing the loss density in the iron core, loss in the transformer can be reduced.Type: GrantFiled: October 19, 2010Date of Patent: October 28, 2014Assignee: Mitsubishi Electric CorporationInventors: Ryuichi Nishiura, Yasuo Fujiwara, Yoshinori Shimizu, Tetsuya Matsuda, Takeshi Imura, Kazuaki Aono, Hiroyuki Akita

Patent number: 5135690Abstract: A process for producing a cylindrical reinforcing fibrous molding by sealing openings at opposite ends of a porous cylindrical disintegratable mold, immersing the mold into an aqueous solution of a molding material containing reinforcing fibers and an inorganic binder, and depositing the molding material onto the outer peripheral surface of the mold by applying suction within the mold to form a molding blank; pressing the molding blank against the mold to adjust the shape of the molding blank; disintegrating the mold to remove it from the blank; and heating the molding blank to partially bond the reinforcing fibers with the inorganic binder.Type: GrantFiled: January 22, 1987Date of Patent: August 4, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takeshi Imura, Masaki Sakakibara, Takahiro Suenaga, Shigeo Kaiho, Kanji Murata, Hitoshi Karasawa, Kazuya Sakamoto, Masahiro Inoue, Masanobu Ishikawa, Takashige Hara

Patent number: 4976305Abstract: The temperature of a casting die is controlled in a low-pressure casting process for pressurizing the surface of molten metal stored in a closed container to fill the molten metal in a die cavity defined in the casting die. The temperature of the casting die is detected by a temperature sensor, and compared with a preset reference die temperature range. The amount of cooling water to be supplied to the casting die is controlled based on the result of the comparison. When the detected temperature of the casting die falls in the preset reference die temperature range, the molten metal starts to be filled in the die cavity.Type: GrantFiled: December 1, 1988Date of Patent: December 11, 1990Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kouji Tanaka, Syugo Kondo, Takeshi Imura, Katsuhiko Ando, Shigemitsu Nakabayashi

Patent number: 4875518Abstract: A light metal alloy such as an aluminum alloy is cast into a casting such as an automobile engine cylinder head under low pressure. A fluid pressure is applied to the surface of a light metal alloy stored in a closed container to introduce the light metal alloy from the closed container through a transfer tube and a sprue into a mold cavity defined in a mold assembly. The introduced molten metal alloy is brought into contact with molds of the mold assembly which have different thermal conductivities, respectively. The time in which the molten metal alloy is solidified is controlled by the molds of different thermal conductivities. The molds may forcibly be cooled by a cooling medium passing therethrough or cooling blocks mounted thereon.Type: GrantFiled: August 17, 1988Date of Patent: October 24, 1989Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takeshi Imura, Katsuhiko Ando, Shigemitsu Nakabayashi, Maki Hirose
