Title: Recording and reproducing device of digital signal
Inventor: ODAKA KENTARO
IPC: G11B20/10
Filed: 1984-08-16
Abstract: PURPOSE:To reduce the effect due to the relation of position between a PG signal and a head and jitter of a drum at reproduction by interrupting a signal succeeding to a fixed pattern for a prescribed time so as to generate substantially a window signal from a PCM signal itself when the fixed pattern is discriminated in a signal recorded on each track. CONSTITUTION:When a 10 bit of the fixed pattern SYNC exists in a block B (the same in case of a block in a PCM data) of a sub code during the running on a track pattern A, a pulse signal SG is generated. Then a mask signal SM having prescribed width, e.g., a width for 360 bit's share is generated based on the pulse signal SG to mask the entire 360 bit. Then the parts of the sub code and the PCM data are masked completely by repeating the operation above at each block, mis-detection of it as a position signal to detect the position of a tracking pilot signal is avoided and it is not required to produce the window signal from the PG signal.

IPC: G04B23/03
Filed: 1994-06-29
Abstract: PURPOSE:To provide an alarm clock having a blood-pressure measuring function while starting its blood-pressure measurement when an alarm sound is stopped. CONSTITUTION:Alarm sound is not stopped even when an alarm stop key K5 is depressed during alarm sound is being given, and the alarm sound is stopped by depressing a blood-pressure measuring key K4. When function for a snoozing is made effective at that time, the generation of the alarm sound is stooped temporarily, and a display, in which the measurement of blood pressure is promoted, is conducted. When the blood-pressure measuring key K4 is not depressed in six min after the alarm sound is stopped, the alarm sound is given again after six min. The alarm sound is given at every six min. until the blood- pressure measuring key K4 is pushed. Accordingly, since blood pressure can be measured while an alarm is stopped by starting the measurement of blood pressure, the result of the measurement of blood pressure under a most stable state at the time of rising is obtained, and measurement of blood pressure is inevitately effected at the time of rising.
