Patent number: 7426111Abstract: A rack structure which is capable of improving heat-dissipating efficiency thereof within a limited space, and a communication apparatus which is capable of enhancing cooling efficiency by applying the rack structure thereto. In the rack structure of the communication apparatus, the air used for cooling printed circuit boards within a lower shelf and thereby increased in temperature is cooled by causing the same to flow through the heat-dissipating duct on a lateral side and is then used again for cooling printed circuit boards within an upper shelf. This makes it possible to increase the heat-dissipating efficiency of the communication apparatus to thereby improve the cooling performance thereof. As a consequence, the necessity of increasing the number of cooling fans or increasing the size of fans becomes small, and the cooling performance of the communication apparatus can be maintained within a limited installation space.Type: GrantFiled: May 11, 2007Date of Patent: September 16, 2008Assignee: Fujitsu LimitedInventors: Hideki Sonobe, Kazuo Hirafuji, Yoshihisa Nakagawa

Patent number: 6198601Abstract: A magnetic head element has one or more rails formed on the surface thereof. Each rail is formed so as to have a tapered angle of 55-85°. To form such a rail, ion milling is conducted; the rail substrate used is allowed to have an inclination angle to 15-60° and is rotated; and there is used, as the ion milling gas, a fluorinated hydrocarbon (e.g., CH2FCF3) gas alone or a mixed gas of said fluorinated hydrocarbon gas and Ar, SF6 or the like. Accordingly, a magnetic head rail shape gives a small variation in flying height between magnetic bead and magnetic disc.Type: GrantFiled: March 16, 1999Date of Patent: March 6, 2001Assignee: Hitachi, Ltd.Inventors: Yasuo Hira, Tamaki Toba, Hirotaka Imayama, Atsuko Ohkawa, Masayasu Fujisawa, Kazuo Nate, Hideki Sonobe, Saburo Suzuki, Eisei Togawa, Hiroshi Ishizaki, Yoshiki Hagiwara
