Patent number: 11100382Abstract: A card-type wireless communication device is provided that suppresses a deterioration in communication performance of the dipole antenna while ensuring a larger coil antenna size in a limited card size. The card-type wireless communication device includes a coil antenna and a dipole antenna. The dipole antenna includes first dipole element including a first connection end connected to a second-frequency-band RFIC element, first linear part that extends from the first connection end along an outer edge of the coil antenna, and a first open end facing the outer edge of the coil antenna via the first linear part. Moreover, a second dipole element includes a second connection end connected to second-frequency-band RFIC element, and a second open end at a position farther from the outer edge of the coil antenna than a shortest distance between the first linear part and the outer edge of the coil antenna.Type: GrantFiled: March 13, 2020Date of Patent: August 24, 2021Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Tatsuya Ochi, Noboru Kato

Patent number: 7735388Abstract: A worsening of drivability is to be kept to a minimum by making a fail-safe control taking the state in the event of failure of a shifting operation into account. When clamping a sleeve to a free rotatable gear and during the period after instructing movement of the sleeve to a clamping position until movement of the sleeve to a predetermined positional range which makes it possible to judge that the sleeve has been clamped to the free rotatable gear, a pushing load for the sleeve is increased if the sleeve is in a fixed state near the balk ring, while if the sleeve is in a fixed state near the free rotatable gear, the sleeve is once returned to a neutral position thereof and is re-clamped to the free rotatable gear. Further, the number of times the sleeve is re-clamped to the free rotatable gear is counted and the use of the free rotatable gear is inhibited in accordance with the counted number of times.Type: GrantFiled: January 24, 2008Date of Patent: June 15, 2010Assignee: Hitachi, Ltd.Inventors: Hiroshi Sakamoto, Tatsuya Ochi, Yoshiyuki Yoshida, Tetsuo Matsumura, Kinya Fujimoto, Masashi Seimiya

Patent number: 7354378Abstract: A large gearshift shock that occurs if a renewed gearshift operation is forcibly carried out in order to meet a new gearshift request made through a driver's operating an accelerator pedal or a signal from an operation lever during a current gearshift operation. Gearshift response lag occurs due to an attempt to avoid the large gearshift shock. To solve these problems, a control system for a gear type transmission is mounted. The control system is provided with a renewed gearshift disabling period, during which any renewed gearshift request to a third predetermined gearshift position made during a gearshift operation from a first predetermined gearshift position to a second predetermined gearshift position is disabled.Type: GrantFiled: November 12, 2004Date of Patent: April 8, 2008Assignee: Hitachi, Ltd.Inventors: Tatsuya Ochi, Toshimichi Minowa, Takashi Okada, Hiroshi Sakamoto, Naoyuki Ozaki

Patent number: 7337046Abstract: An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.Type: GrantFiled: January 2, 2007Date of Patent: February 26, 2008Assignee: Hitachi, Ltd.Inventors: Toshimichi Minowa, Tatsuya Ochi, Satoru Kuragaki, Mitsuo Kayano, Tokuji Yoshikawa
