Patent number: 7445091Abstract: An electrically operated brake device in which braking force differences between electrically operated brakes are reduced to prevent unstable vehicle traveling during braking. Motors 13 of electrically operated brakes are returned to standard positions during the stop of a vehicle and the motor 13 of each of the brakes is driven for a predetermined amount, pressing a brake pad 17 against a disc rotor 18 to produce a braking force. An electric current value of each motor 13 in the above operation is measured and differences between the values are calculated. Electric current of each motor is increased or decreased so that there is no current difference between the motors 13. Based on a drive amount of each motor in this operation, standard positions of the motors are determined and updated. Repeating the above operations reduces braking force differences between the brakes.Type: GrantFiled: June 21, 2004Date of Patent: November 4, 2008Assignee: Hitachi, Ltd.Inventors: Yoshinari Kawahara, Kousaku Ohno, Atsushi Yokoyama, Mitsuhide Sasaki

Patent number: 6089208Abstract: When the power source of a motor is turned off, a cam connected to the motor is held at an initial default stopping position by a return spring generating a torque in one direction and a throttle valve connected to a cam via an arm, and a valve gear is held at a corresponding default opening position. When the motor rotates and generates its torque, the arm first closes the throttle valve to a prescribed minimum opening and then opens the throttle valve in the fully open direction.Type: GrantFiled: September 18, 1998Date of Patent: July 18, 2000Assignee: Hitachi, Ltd.Inventors: Takehiko Kowatari, Shigeru Tokumoto, Kousaku Ohno

Patent number: 6051613Abstract: A pharmaceutical composition containing an extract from inflammatory tissue inoculated with vaccinia virus may be used to suppress the death of cells caused by endotoxin, and suppress excessive production of nitrogen monoxide induced by endotoxin. The extract may also be used to relieve hypotension induced by endotoxin. In sepsis and other serious bacterial infectious diseases, endotoxin (an intracellular toxin) is produced and a shock symptom is induced by its action. The extract, having an excellent inhibitory action toward endotoxin-induced toxicity, is quite useful for the treatment or the prevention of endotoxin-induced shock symptoms, sepsis and various symptoms accompanied thereby. In addition, the extract has an inhibitory action towards abnormal nitrogen monoxide production during the diseased state and, therefore, it is also useful as a therapeutic and preventive agent for diseases wherein an excessive nitrogen monoxide production occurs, such as acute hypotension.Type: GrantFiled: January 5, 1998Date of Patent: April 18, 2000Assignee: Nippon Zoki Pharmaceutical Co., Ltd.Inventors: Kousaku Ohno, Jin-emon Konishi, Seishi Suehiro
