Title: Accidental sound detector
Inventor: SERI TOSHIMITSU
IPC: G10L15/10
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To maintain a record longer than a fixed period without overwriting the recording period of a recording medium by measuring the recorded number of detected accidental sounds every fixed time and varying the amplitude of an inputted acoustic signal according to the recorded number or the variation of the recorded number so as to restrict recorded number. SOLUTION: At the time of discriminating an accidental sound, an accidental sound detecting circuit 11A sends a detection signal 11a to a recording controller 12 and sends it to a counter circuit 16, which adds one counter value whenever the signal 11a is inputted. Then whenever an output signal 17a from a timer circuit 17 is inputted, the circuit 16 outputs a counted value 16a to a comparing part 18 and simultaneously returns the counted value to zero. Whenever the value 16a is inputted, the part 18 compares a reference value 19a from a reference signal generation part 19 and the value 16a with each other and sends the comparing result to an amplitude control circuit 20. The circuit 20 stepwise controls the amplitude of an amplifier 15 according to the comparing result 18a.

Title: Head switching device
Inventor: NAKADOKORO TSUGUTADA
IPC: G11B15/14
Filed: 1985-04-16
Abstract: PURPOSE:To prevent the generation of head switching noises on a screen by performing the head switching actions in the horizontal synchronizing signals not in the video signals. CONSTITUTION:The head switching reference signal 151 produced from the signal showing the revolving phase of a head cylinder and showing the head switching position is supplied to the D input terminal of a D type flip-flop 11. While the horizontal synchronizing signal 52 produced from the reproduced video signal through synchronizing separation is supplied to a clock input terminal (ck). Then an output 53 is obtained. This output 53 rises at the rise part of the first horizontal synchronizing signal after the signal 51 has the rise from the Q output terminal of the flip-flop 11 and is inverted at the rise part of the first synchronizing signal after the signal 51 has the fall. Thus the head switching position is always set into the horizontal synchronizing signal by extracting a consecutive video signal output with said output 53.

Title: Dimension measuring method
Inventor: ISHIDA TAKAHIRO
IPC: G01B17/00
Filed: 1991-03-19
Abstract: PURPOSE:To accurately measure the inside dimension of an object to be measured under a nondestructive condition by measuring and processing a photo-acoustic signal generated by a photo-acoustic effect in the vicinity of the invisible end face of the object. CONSTITUTION:After a sample 12 having a tapered section 12a is housed in a closed cell 13 and the cell 13 is sealed, the sample 12 is placed on the stage of an optical microscope 6 and set near the optical focal point of the microscope 6. Then the surface of the sample 12 is irradiated with a laser beam of an adequate power by oscillating an argon laser 3. When photo-acoustic measurement is performed on the tapered section A of the sample 12 by using a microphone 14, personal computer 10, etc., a phase change is generated by the edge effect of the end face 12 of the sample 12. Namely, the phase value gradually decreases as approaching the end face 12b and abruptly rises and forms an edge at the end face 12b after decreasing to a minimum value. Since the maximum variation of the phase change and dimension (depth) of the end face 12b are in a proportional relation, the dimension of the end face 12b can be found from the maximum variation. Thus the inside dimension of the sample can be accurately measured in the order of over ten to several hundred m under a nondestructive condition.
