Abstract: PURPOSE: To omit both the software and the hardware which are hitherto necessary for the multiple address function by storing the information into the memory and then sending the terminals by one unit with switching of the sequence in case the multiple address is given to the terminal connected to the switching device.  
     CONSTITUTION: In case the multi-address communication is carried out for terminals R 1 ∼R n  connected to switching device CH through transmission terminal TX 1 , circuit L tx1  is connected to circuit L rxo  via exchange unit EX but only one circuit can be transmitted at a time since the multiple address function is not provided to device CH. For instance, when reception circuit L r1  is connected first and then transmitted to reception terminal device R 1 , the address and the picture image contents are stored temporarily in storage unit ST for the transmission component to reception terminals R 2 ∼R n . Then the picture image contents is read out from unit ST after the transmission of the picture signal is over to recep tion terminal R 1  and then transmitted to next reception terminal R 2 . After this, the transmission is carried out in sequence.

IPC: G01S15/08
Filed: 1987-02-06
Abstract: PURPOSE:To enable the accurate measurement of a distance irrespective of the existence of an unperceivable area, by canceling a first reflection wave when a reverberation wave is superposed on the first reflection wave, and by measuring the distance on the basis of a second reflection wave and thereafter. CONSTITUTION:An ultrasonic oscillator 3 delivers in ultrasonic wave to an ultrasonic transmission-reception head 1, and the head 1, in its turn, emits the ultrasonic wave toward an object to be measured and receives a reflection wave from the object. Upon receiving a timing signal from the oscillator 3, a gate signal generating means 8 generates a reference signal and a plurality of gate signals being different by a prescribed length from the reference gate signal. When a signal of a first reflection wave received by the head 1 is superposed on a reference gate set on the basis of a reverberation wave, a gate means 7 cancels the first reflection wave and generates signals of a second reflection wave and thereafter as measuring signals. From these measuring signals, the distance between the head 1 and the object to be measured is computed by a distance computing means 9.
