Patent number: 9030041Abstract: A fourth constant-voltage power circuit directly powered from an on-vehicle battery is connected, in parallel through a serial resistor, to a second constant-voltage power circuit powered from the on-vehicle battery through an output contact of a power relay, and is connected to a drive power terminal of a microprocessor. When the output contact is closed, the microprocessor operates with an output voltage of the second constant-voltage power circuit, and an output current of the fourth constant-voltage power circuit is limited to less than or equal to a predetermined value by the serial resistor. During the operation stop at which a power switch is open, a micro standby current is supplied from the fourth constant-voltage power circuit to the microprocessor.Type: GrantFiled: October 6, 2011Date of Patent: May 12, 2015Assignee: Mitsubishi Electric CorporationInventors: Mitsunori Nishida, Tomohiro Kimura, Masahide Fujita, Yuji Zushi

Patent number: 8018702Abstract: The on-vehicle electronic control device includes a main power supply circuit fed with power from an on-vehicle battery through an output contact of a power supply relay and a main power supply terminal of a connector to supply a stabilized control voltage to a microprocessor. When contact failure occurs in the main power supply terminal, the main power supply circuit is fed with bypass power from the output contact through a first electrical load and a commutation diode to perform the one of the report of the abnormality and the storage of the abnormality occurrence history information. A bypass power fed state is detected when an input voltage to the main power supply circuit is lower than a power supply voltage of the on-vehicle battery.Type: GrantFiled: November 7, 2008Date of Patent: September 13, 2011Assignee: Mitsubishi Electric CorporationInventors: Tetsuo Maeda, Masaharu Yuhara, Masahide Fujita, Michihiro Takata, Takayuki Yano, Daisuke Yase

Patent number: 6883123Abstract: A microprocessor runaway monitoring control circuit with which self-diagnosis of a watchdog timer WDT can be carried out safely and cheaply even during operation of the microprocessor (CPU). A microprocessor 101 supplies first and second watchdog clearing signals WD1 and WD2 to first and second watchdog timers WDT1 and WDT2, and when the both of the watchdog clearing signals WD1 and WD2 stop, the microprocessor 101 is reset by way of a logical connector circuit 122. The microprocessor 101 has failure diagnosing means 103 which intentionally stops the first watchdog clearing signal WD1 and diagnoses the response of the first watchdog timer WDT1 on the basis of a monitor signal MN1 and stops the second watchdog clearing signal WD2 and diagnoses the response of the second watchdog timer WDT2 on the basis of a monitor signal MN2, whereby diagnosis of the watchdog timers WDT1, WDT2 is carried out without the microprocessor 101 being stopped.Type: GrantFiled: April 23, 2002Date of Patent: April 19, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kohji Hashimoto, Katsuya Nakamoto, Masahide Fujita, Hiroyuki Mitsueda

Patent number: 6411872Abstract: To secure normal operation and then restart a microprocessor (CPU) when a CPU built into an on-vehicle electronic apparatus runs away. A number of on-vehicle loads driven from a CPU, a watchdog timer for monitoring the CPU to reset and restart it on occurrence of an abnormality, and a memory element for storing generation of the reset output are provided, and load driving elements or a load relay is rendered inoperative by output of the memory element. The memory element is reset by cutting off or reclosing the power switch, and an on-vehicle electronic apparatus returns to a normal state.Type: GrantFiled: August 2, 2001Date of Patent: June 25, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masahide Fujita, Kohji Hashimoto, Katsuya Nakamoto

Patent number: 6227732Abstract: A sheet package according to the present invention is formed of a synthetic resin sheet and designed in a square-cornered bag shape to have an outer shape corresponding to sheets and a height at which plural sheets are stacked. The sheet package thus constructed is supplied to a user in a state where plural sheets are beforehand stacked and accommodated in a sheet package and packed by a vinyl bag or the like by a sheet maker. Accordingly, the user merely opens the vinyl bag to set the sheets into a sheet tray of a printer by the sheet package.Type: GrantFiled: September 17, 1998Date of Patent: May 8, 2001Assignee: Sony CorporationInventors: Ken Higuchi, Hiroshi Katsuno, Masahide Fujita
