Title: Pager
Inventor: OKAMURA MASAMITSU
IPC: H04Q7/16
Filed: 1994-04-18
Abstract: PURPOSE:To provide a time management function to the pager by storing time data to a memory when time data are sent from a caller and a registration key is operated and informing a carrying person of it when the time comes. CONSTITUTION:When a caller sends a message including a time, the caller adds a prescribed identifier to data representing the time and enters the data with a key, the data are converted into an FSK signal and sent. A pager of a carrying person receives the FSK signal and the person recognizes a call notice by lighting, a sound or a time indication displayed on an LCD 35. When the carrying person observes the display time and depresses a registration key in a key 31, a prescribed registration routine in a ROM 22 is executed and the display time is registered in a RAM 23. A clock circuit 24 applies interrupt to a CPU 21 for each prescribed time to read count time data from the circuit 24 and the data are compared with the time data registered in the RAM 23. When the time indicated by the circuit 24 comes to the time of the data stored in the RAM 23, it is reported by lighting of the LED 32, an LCD 35 or an alarm 34.

Title: Hand-display type electronic time piece
Inventor: MORIYA TATSUO
IPC: G04C9/00
Filed: 1982-06-16
Abstract: PURPOSE:To eliminate malfunctioning of a stepmotor by arranging a switch signal detection circuit to override any switching input when a correction switch is operated at an interval shorter than the transient vibration period of the step motor. CONSTITUTION:A correction switch 1 is closed at the timing T1 and T2 to generate a signal S1 containing a chattering waveform which is converted to a signal S3 with a chattering prevension circuit 2. A signal S7 outputted from a timer circuit 15 won't go to 'H' before the elapsing of 62.5m sec or more. Any switching input is overrided when a chattering of 5.9m sec or less is generated or when the correction switch is operated again at an interval of 62.5m sec or less after the operation thereof. As the transient vibration period of stepmotors now in use is 50m sec or so, an electron corrector can be realized free from malfunctioning of stepmotors.
