Patent number: 7292009Abstract: Simplifying the controller of hybrid type drive unit. The output of a generator driven by engine is connected directly to a motor 7 through a converter or switching circuit 10 without being charged on any battery. The output of each phase of the generator is inputted to the converter 10. A timing controller 126 controls the conduction phase of a thyristor bridge 101 in the converter 10 so as to adjust the quantity of output power. A synchronous standard for phase control is formed based on output wave of an auxiliary winding 26 of the generator. A voltage detector 124 detects an applied voltage on the motor 7 as a motor rotation speed and the conduction angle is increased or decreased so as to maintain a detected voltage at a target value.Type: GrantFiled: September 8, 2004Date of Patent: November 6, 2007Assignee: Honda Motor Co., Ltd.Inventors: Toshiaki Kawakami, Tsutomu Inui, Tsutomu Wakitani

Patent number: 7178037Abstract: An ID (MID) is attached to each individual optical disk, and content is encrypted with a Content-Key and registered. In addition, a system server device maintains a Client ID of a client terminal device, HDD-ID of a hard disk drive (HDD), and MC-ID of a memory card respectively held as user entry information. When the user wants to copy the content, together with the optical disk MID, the MC-ID is sent to the system server side. The system server device identifies the user by referencing the MC-ID in the user entry information, and returns a Content-Key, which is used when encoding content. On the user side, content stored in the optical disk is decrypted using the returned Content-Key and copied to the HDD. Accordingly, copying of content is allowed only for an authorized user who is the lawful owner of the storage media.Type: GrantFiled: February 20, 2002Date of Patent: February 13, 2007Assignee: Sony Computer Entertainment Inc.Inventors: Muneki Shimada, Shinichi Okamoto, Masaharu Yoshimori, Tsutomu Inui, Keiso Shimakawa, Toyoshi Okada, Makoto Kubo, Mitsuhiro Nakamura

Patent number: 7134261Abstract: In the working machine wherein the output of an engine generator is directly supplied to a motor for travel without using the intermediary of a battery, preventing the engine from slowing down. The generator G is directly connected to the motor 7 and there is no battery that stores the output of the generator G. CPU 102 decreases the power supply for the motor 7 when it has been anticipated that the engine revolutions will be decreased. The number of the engine revolutions is detected according to the period of the waveform of an output of the generator G. The alternating current waveform that has been drawn out from one phase of the winding of the generator G is shaped into a rectangular waveform. CPU 102 detects the period of the shaped waveform. When the detected period has become larger, the CPU 102 determines that the engine revolutions is about to decrease.Type: GrantFiled: March 9, 2004Date of Patent: November 14, 2006Assignee: Honda Motor Co., Ltd.Inventors: Tsutomu Inui, Hiroo Kanke, Tsutomu Wakitani, Toshiaki Kawakami

Patent number: 7103100Abstract: In case of decoding by a software process, in the process 1, video data of a decoded frame corresponding to a management ID stored at the head of an output FIFO 4 at its time point is read out and outputted. In the process 2, audio data is decoded. In the process 3, the video data is decoded. The decoded video data is stored in a video frame buffer and its management ID is stored in the output FIFO 4 in the outputting order. When the process 3 cannot be finished, the process 3 is interrupted during the process and the image of the frame stored at the head of the output FIFO 4 is outputted. After that, when the process 2 is finished, the decoding process of the process 3 which was temporarily interrupted is restarted. In case of performing the encoding by the software process, an encoding amount of the video data as a processing target of the encoding is predicted. Subsequently, whether an empty capacity enough to store the data of the predicted encoding amount exists in a code buffer or not is discriminated.Type: GrantFiled: March 8, 2000Date of Patent: September 5, 2006Assignee: Sony CorporationInventors: Ikuo Tsukagoshi, Tsutomu Inui, Masahito Yamane

Patent number: 6949898Abstract: The output of an engine driven generator G is directly supplied to a motor 7 for travel without the intermediary of a battery. The output capacity of each of the generator G and motor 7 is determined so that the maximum output of the generator G may substantially coincide with the maximum control electric power that is supplied to the motor 7. The over-current with respect to the motor is suppressed by the output impedance of the generator G. A CPU 102 performs output control so as for the output to conform to the load according to the electric current with respect to the motor. If the electric current increases, the voltage is varied to a level thereof that conforms to that electric current for ensuring sufficient torque.Type: GrantFiled: March 9, 2004Date of Patent: September 27, 2005Assignee: Honda Motor Co., LtdInventors: Tsutomu Inui, Tsutomu Wakitani

Patent number: 6860348Abstract: A dual-motor electric vehicle having a control section that determines whether three conditions are satisfied, (1) that a straight-ahead travel instruction has been supplied to the vehicle, (2) that an actual number of motor rotations of an electric motor is less than a target number of motor rotations, and (3) that a motor control signal for bringing the actual number of motor rotations closer to the target number has reached a predetermined upper limit output value. When all conditions are satisfied for at least one of the electric motors of the dual-motor vehicle, the control section performs a downward motor-rotation correction process for at least one of motors by incrementally reducing one of the target number of motor rotations and the upper limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors substantially coincide with each other.Type: GrantFiled: October 22, 2002Date of Patent: March 1, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsutomu Wakitani, Tsutomu Inui, Hiroo Kanke
