Patent number: 8994324Abstract: A charge capacity parameter estimation system for an electric storage device capable of charging and discharging is provided, which can accurately estimate a charge capacity parameter indicative of a charge capacity of the electric storage device. The charge capacity parameter estimation system for a battery includes an ECU and a sensor unit. The ECU estimates that an actual charge capacity of the electric storage device is less than an estimated charge capacity, when a charging state of the electric storage device is detected, in a case where a generated voltage of a power generator is controlled such that the battery executes a discharging operation to an auxiliary equipment.Type: GrantFiled: September 11, 2012Date of Patent: March 31, 2015Assignee: Honda Motor Co., Ltd.Inventors: Masatoshi Nishina, Naoya Hayashida

Patent number: 7430085Abstract: A signal processing device having a feature of analog-to-digital converting a burst signal has a feature of selecting data bus to notify a disk control device 2 of a conversion result via an NRZ data bus. The disk control device 2 includes means for storing the result of the analog-to-digital conversion of said servo positional signal. The positional signal of a head of the disk device is digitalized in an R/W channel. Sampling for digital conversion is performed in only a window which is defined only in the vicinity of peaks of the positional signal. The values of peaks which are obtained by sampling are averaged by an averaging circuit. This enables the influence of noise occurred outside of the window to be eliminated. Although the noise in the window is sampled, its adverse influence is suppressed by the averaging processing.Type: GrantFiled: August 22, 2006Date of Patent: September 30, 2008Assignee: Hitachi Global Storage Technologies Japan, Ltd.Inventors: Motoyasu Tsunoda, Yukie Miyazawa, legal representative, Hitoshi Ogawa, Ryutaro Horita, Takashi Nara, Masatoshi Nishina, Katsumi Yamamoto, Shoichi Miyazawa

Patent number: 6836712Abstract: Abnormality detection is conducted with respect to data indicative of operating state of an apparatus, the abnormality type is then discriminated and a check is made as to whether the data are already recorded in association with the discriminated abnormality type in a memory region corresponding to the data, and if not, the data are recorded in association with the discriminated abnormality type there. Since, multiple recording of similar data related to transient abnormalities and other such events that are likely to occur repeatedly can be prevented, important data related to a diversity of abnormalities and failures can be efficiently recorded in the memory. Viewed from another angle, this means that the capacity of the memory can be reduced and that a cost-reducing effect can be anticipated. In addition, data important for troubleshooting abnormalities and failures, most notably transition period data, can therefore be efficiently recorded in the memory.Type: GrantFiled: August 7, 2002Date of Patent: December 28, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Masatoshi Nishina

Patent number: 6623402Abstract: An apparatus includes a linear solenoid valve regulating an oil pressure supplied to a clutch, a hydraulic switch being switched on and off upon receipt of a switching oil pressure, and a control unit controlling the actuation of the solenoid valve. A pressure-increased side signal oil pressure is detected which results when the hydraulic switch is switched on and off while a control signal is sent to the solenoid valve to increase a control oil pressure from a predetermined lower pressure to a predetermined higher pressure, and a pressure-decreased side signal oil pressure is detected which results when the hydraulic switch is switched on and off while the control signal is sent to decrease the control oil pressure from the predetermined higher pressure to the predetermined lower pressure. When a difference between these signal oil pressures exceeds an abnormalities determination value, it is determined that the solenoid valve is abnormal.Type: GrantFiled: April 10, 2002Date of Patent: September 23, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masatoshi Nishina, Chihiro Matsubara, Akio Tsuura
