Filed: 1978-12-11
Abstract: PURPOSE:To improve and stabilize transmission efficiency by using a filler with a little variation in acoustic characteristics with water pressure by making flank and bottom-surface directions, viewed from a vibrator, equivalent to those with no load. CONSTITUTION:When the wavelength of an ultrasonic wave, generated by vibrator 1, in filler 6 is denoted by (lambda), perforation sizes of vibrator 1 and metal case 5 are fixed so that L1 is (mlambda) and L2 is (nlambda) [(n) and (m) are natural integers]. Namely, L1 is twice the distance between the bottom of vibrator 1 and the deepest point of reflecting surface R1, and L2 is twice that between the flank of vibrator 1 and the deepest point of reflecting surface R2. Here, an ultrasonic wave emitted from the bottom of vibrator 1 propagates in filler 6 vertically and returns to the bottom of vibrator 1 after being reflected twice by reflecting surface R1. Then, the run distance of the ultrasonic wave is L1. Similarly, an ultrasonic wave from the flank of vibrator 1 advances in filler 6 horizontally and then returns to the flank of vibrator 1 after being reflected twice by reflecting surface R2. Then the run distance of the ultrasonic wave is L2. Either returning wave is in phase with the emitted wave and a load viewed from vibrator 1 can be considered to be zero.

Filed: 1989-06-16
Abstract: PURPOSE:To prevent malfunction even when a dial information generator is disconnected by discriminating whether or not the dial information generator is connected to a connection section and by controlling a switch acquiring and releasing the line. CONSTITUTION:When a card is loaded to a loading location 14, a microswitch 20 is closed, a CPU 1 detects it, and when a line of a telephone set 11 is connected, the CPU 1 recognizes the line connection through an NCU 9 and whether or not a light is made incident in a photodetector 19 is detected at a prescribed interval. On the other hand, a desired destination is retrieved by a display section on the card and when a transfer button is depressed, a light emitting element 18 is lighted according to dial information. Since a photodetector replies at the telephone set side, the CPU 1 stores a number corresponding to the photodetector and the information sent succeedingly to the RAM 3 and display the result for dialing immediately when the scanned photodetector is lighted. Thus, when the card is loaded to the telephone set and the line is not connected, the optical information to the photodetector of the telephone set is not inputted and malfunction due to an external light is prevented.
