Patent number: 6919043Abstract: At the step of preheating the container, in addition to heating of the whole container, a neck portion (1a) of the container may be heated separately. Alternatively on the step of preheating the container, while whole container is heated by a hot air blast which is supplied in the container, neck portion (1a) of the container may be heated separately. Since it is difficult to increase the temperature of the neck portion as compared with other portions, by heating the neck portion separately, the effect of the preheating is performed more effectively. It is desirable that the hot air blast is supplied from the nozzle inserted in the container. For example by the method of spraying hot air blast from the outside of the portions, heating of the neck portions can be performed.Type: GrantFiled: February 12, 2002Date of Patent: July 19, 2005Assignee: Dai Nippon Printing Co., Ltd.Inventors: Atsushi Hayakawa, Makoto Hayashi, Masatoshi Takagi, Akira Koyama

Patent number: 6882502Abstract: A thin-film magnetic head includes a lower core layer, a gap layer formed on the lower core layer with a lower pole layer therebetween, an upper pole layer formed on the gap layer, an upper core layer formed on the upper pole layer, and a Gd-defining layer for defining the depth in the height direction of the joint surface between the gap layer and the upper pole layer. The width in the track width direction of the gap layer is smaller than or equal to the width in the track width direction of the upper pole layer when viewed from the surface facing the recording medium. By employing such a thin-film magnetic head, the width in the track width direction of the gap layer can be decreased, and thus track narrowing is achieved.Type: GrantFiled: December 14, 2001Date of Patent: April 19, 2005Assignee: Alps Electric Co., Ltd.Inventors: Kiyoshi Sato, Hideki Gochou, Hisayuki Yazawa, Kiyoshi Kobayashi, Akira Koyama

Patent number: 6704162Abstract: A track width regulating section having a track width, which is smaller than the resolution obtained by the wavelength of the light used for exposure and development of a resist, is formed between a lower core layer and an upper core layer. Since the width of the upper core layer is larger than the track width, magnetic saturation can be effectively reduced. Inclined faces are formed on the upper surface of the lower core layer so as to be inclined in directions away from the track width regulating section, thereby adequately preventing write fringing.Type: GrantFiled: August 9, 2002Date of Patent: March 9, 2004Assignee: Alps Electric Co., Ltd.Inventors: Kiyoshi Sato, Hideki Gochou, Kiyoshi Kobayashi, Hisayuki Yazawa, Akira Koyama, Minoru Yamada
