Title: Transmitter-receiver
Inventor: IKEDA TAKASHI
IPC: H04R29/00
Filed: 1985-09-17
Abstract: PURPOSE:To make it possible to simply inspect the characteristics of a transmitter-receiver without putting a ship having sonar mounted thereto in a dock, by temporarily stopping transmitting function during the operation of sonar to apply a test signal to the transmitter-receiver. CONSTITUTION:When a transmitting pulse is outputted from a transmitting part, because the voltage thereof is high, two sets of diode anti-parallel pairs consisting of diodes 3, 4 and diodes 5, 6 are shortcircuited. The transmitting pulse is almost applied to an electrostriction vibrator 1 and a matching wire coil 2 to emit a sonic wave from the vibrator 1. Because the diode anti-parallel pairs are connected to the input terminal of a receiving part 12 at that tie, only voltage two times the rising voltage of the diodes is inputted to said input terminal and the receiving part 12 is protected from the transmitting pulse. Next, at the time of reception, because the terminal voltage of the vibrator 1 is low, the diode anti-parallel pairs come to an open state. Further, said voltage is inputted to the receiving part 12 through the wire coil 2 resonating almost in series to the electric capacity of the vibrator 1 and outputted as a receiving signal 101. By this method, the characteristics of a transmitter-receiver 21 can be simply inspected.

Title: Measuring apparatus of moisture content
Inventor: KUROKI YASUBUMI
IPC: G01N27/04
Filed: 1981-12-18
Abstract: PURPOSE:To prevent the generation of electric polarization of a sample interposing between electrodes and to make the measurement of moisture content having a small output error possible by stabilizing an electric current between the electrodes, by applying pulse voltage having constant period between the electrodes. CONSTITUTION:When a sample 2 is interposed between electrodes 1 and pulse voltage is applied between the electrodes 1 by a pulse generator 6 and a transistor 5, an electric current having periodicity flows on between the electrodes 1 in correspondence to this pulse voltage and this current is led into a logarithmic converter 4 through the transistor 5. And, each crest value of logarithmically converted current depends upon the resistance value between the electrodes. Accordingly, the generation of electric polarization in the sample 2 interposing between the electrodes 1 is prevented by applying the pulse voltage and the electric current depending upon the resistance value of only the sample requiring the measurement of the moisture content is obtained.
