Patent number: 7992095Abstract: Since a editing character string is managed by an input server, an application device cannot know whether scrolling is necessary. Accordingly, there has been a problem that it is impossible to properly realize a scroll function. Accordingly, a receiving unit receives an instruction from a user operation or an application device, and a character string editing unit edits a character string according to the instruction received. Further, an output management unit manages output, and a state notifying unit notifies a change of the internal state to the application device. When a output area does not have enough empty space to display an editing character, the state notifying unit instructs the application device to shift the confirmed character string. The application device, upon receiving the instruction, scrolls the confirmed character string upward.Type: GrantFiled: April 25, 2005Date of Patent: August 2, 2011Assignee: Panasonic CorporationInventors: Yoshio Yamamoto, Masahiro Muikaichi

Patent number: 7808741Abstract: Embodiments of the present invention help to adjust the recess depth of a head element portion of a head slider. In an embodiment of the present invention, in a test step in manufacturing an HDD, the HDD examines the recess depth of a head element portion and decreases and adjusts the recess depth if the recess depth of the head element portion does not satisfy the predetermined condition. The HDD moves an actuator to a ramp of a retract position and supplies power to a heater in a head slider. If the heater power is large, the head element portion undergoes plastic deformation. The plastic deformation of the head element portion decreases the recess depth of the head element portion.Type: GrantFiled: November 21, 2008Date of Patent: October 5, 2010Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Tsuyoshi Matsumoto, Futoshi Kitaizumi, Yoshio Yamamoto, Hidetsugu Tanaka, Masayuki Ishikawa

Publication number: 20070227563Abstract: Embodiments in accordance with the present invention provide straightening plates at the upstream side of a cleaning tank and a straightening plate at the downstream side of the object to be cleaned. Apertures are arranged in the planes of the respective straightening plates. An aperture ratio of the upstream straightening plates is set larger than the ratio of the downstream straightening plate. For example, the aperture ratio of the upstream straightening plate may be set at a value between 10% and 25%, and the aperture ratio of the downstream straightening plate is set at a value between 2.5% and 10%. With this, the flow of liquid in the cleaning chamber sandwiched between the upstream and downstream straightening plates can be brought to a pseudo-laminar flow. Contaminants separated from the object to be cleaned are moved quickly to the discharge chamber and are removed by a filter.Type: ApplicationFiled: April 2, 2007Publication date: October 4, 2007Applicant: Hitachi Global Storage Technologies Netherlands B.

Patent number: 6626138Abstract: An internal combustion engine (E) includes a crankshaft (5), and a bearing cap (8) supporting the crankshaft (5) for rotation. Permanent magnets (20) serving as magnetic field creating members are attached to the balance weights (W1a to W6a) formed integrally with the webs (W1 to W6) of the crankshaft (5). Coils (21) are attached to the bearing cap bodies (A1 to A4) of the bearing cap (8). The permanent magnets (20) and the coils (21) form electromechanical transducers (M1 to M6). A small gap can be formed and maintained between the permanent magnets (20) and the corresponding coils (21) with reliability without entailing substantial increase in the size of the internal combustion engine. The electromechanical transducers (M1 to M6)are controlled according to the operating mode of the internal combustion engine so as to serve as electric motors or generators.Type: GrantFiled: January 2, 2002Date of Patent: September 30, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takehiko Sayama, Takatoshi Ogami, Yoshio Yamamoto, Hiromitsu Sato, Kazuyuki Iwata

Patent number: 6603653Abstract: An electric double layer capacitor having an electrode rolled body contained in an outer packaging can. The electrode rolled body includes a positive electrode plate having a positive electrode foil, on both sides of which an active substance is applied, a negative electrode plate having a negative electrode foil, on both sides which the active substance is applied, and a separator interposed between these electrode plates, and is obtained by winding the above parts. The negative electrode foil is electrically connected directly to a bottom of the outer packaging can so that heat generated in an interior of the electric double layer capacitor is efficiently transferred to the outer packaging can from the negative electrode foil. The negative electrode foil has a greater thickness than that of the positive electrode foil, which is not electrically connected to the outer packaging can, so that heat quantity transferred is made large.Type: GrantFiled: August 6, 2002Date of Patent: August 5, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshiyuki Matsuoka, Kenji Matsumoto, Tomokazu Shohoji, Kentaro Shibuya, Yoshio Yamamoto
