Patent number: 6904532Abstract: A portable electronic device including a USB connector, an internal power source, a USB controller to execute data communication processing for data communication with a personal computer connected to the USB connector, a main CPU to execute device operation processing for usual operation of the device. When the USB controller executes data communication processing, the device is supplied with power at high voltage from the personal computer through the USB connector. When the main CPU executes device operation processing, the device is supplied with power at low voltage from the internal power source. Accordingly, this makes not only high speed data communication available, but also prolongs the life of the internal power source.Type: GrantFiled: December 26, 2000Date of Patent: June 7, 2005Assignees: Sanyo Electric Co., Ltd., Sanyo Technosound Co., Ltd.Inventor: Katsuyuki Matsumoto

Patent number: 6515944Abstract: A disk playback device including a memory for temporarily storing data from a pickup and outputting the data as delayed by a predetermined period of time, manual keys, and a system control circuit for detecting the playback end of a disk from the playback data from the pickup. The memory has connected thereto an erase circuit for erasing data remaining in the memory. The system control circuit produces different flag values in a first case wherein the control circuit detects the disk end to terminate playback of the disk and in a second case wherein the user manipulates one of the manual keys to terminate the playback. A memory control circuit is connected to the memory and the system control circuit. In the first case, the memory control circuit inputs to the memory playback data of another disk replacing the disk as continued from the data remaining in the memory.Type: GrantFiled: March 1, 1999Date of Patent: February 4, 2003Assignees: Sanyo Electric Co., Ltd., Sanyo Tecnosound Co., Ltd.Inventors: Masanao Yoshida, Yoshimasa Ono, Katsuyuki Matsumoto, Hitoshi Miyamoto

Publication number: 20010005878Abstract: A data reproduction device comprises a CPU for reading out data from a memory card having a controller mounted thereon and a DSP for giving the read data required processing. The controller of the memory card is so constructed that an active mode is set for reading out the data under the current consumption of a first current value in response to memory access, and thereafter a standby mode automatically follows for waiting for next memory access under the current consumption of a second current value. The CPU reads out the data intermittently from the memory card at a first bit rate, and store the data to a buffer. The data stored in the buffer is read out at the second bit rate lower than the first bit rate, and supplied to the DSP.Type: ApplicationFiled: December 26, 2000Publication date: June 28, 2001Applicant: SANYO ELECTRIC CO., LTDInventors: Tsutomu Sasaki, Katsuyuki Matsumoto, Toru Kamimura

Patent number: 6104678Abstract: A system control circuit checks a memory for data therein through a memory control circuit upon a pickup reaching the end of the disk. When at least a predetermined quantity of data remains in the memory, signaling sound generating means produces a signaling sound three times and a display portion is caused to flash. On the other hand, if the quantity of data remaining in the memory is not greater than a predetermined amount, the sound generating means produces a prolonged signaling sound once and causes the display portion to flash.
