Title: Printer
Inventor: KIUCHI MASAYOSHI
IPC: G06F3/12
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To hold a power source until printing is finished even when a human sensor does not sense a person by providing the sensor and a means for deciding an operating state of a printer, and disposing a means for controlling the power source of the printer. SOLUTION: A level setting circuit 3 is connected to a human sensor 2 to set a detecting distance of an infrared detection signal of the sensor 2. The sensor 2 outputs a 'high' level when detecting a person within a distance set by the circuit 3 by a detected infrared signal, and inputs the signal to a signal processing circuit 4. The circuit 4 removes chattering of its input signal. When the circuit 4 effectively confirms that a signal of the sensor 2 is the 'high', the circuit 4 recognizes the signal connected to a main power source 5 as the 'high' level to turn on the power source 5. When the power source 5 is turned on, a printing unit 6 starts operating to allow printing.

Title: Automatic correction system for system clock
Inventor: HOSHIKA TOMOAKI
IPC: G06F1/14
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To minimize the necessary time correction frequency by keeping the error of a built-in clock in an allowance range that is previously decided and calculating a correction time interval for every built-in clock to attain the self-correction of time. SOLUTION: When the time shown by a built-in clock 12 is coincident with the next correction time that is stored in a next correction time storage means 6, a time monitoring means 7 gives a time correction request to a time setting means 11. The means 11 corrects the time equivalent to an estimated error stored in an error allowance storage means 4. A calculation means 5 adds the self-correction time interval stored in a self-correction time interval storage means 13 to the time corrected by the means 11. Then the means 5 sets this addition time to the means 6 as the next correction time. Thus, the necessary time correction frequency of the clock 12 can be automatically minimized.
