The purpose of this study is to investigate the performances of the electronic units installed out-board the pressure hull of the deep submergence research vehicle and the other deep sea equipments. This paper presents the results of the measurement of the electric characteristics of various devices, i. e., a resistor, a condenser, an operational amplifier, a diode, a thyristor, and many electronic circuits. Each devices were coated by an insurating rubber and tested with the finger-pin-closer type high hydrauric vessel at max. 450 kgf/cm2. As a results, the resistance of the metal film resistor was 1% low, the capacitance of the electrolytic capacitor was nearly constant, and the gain of the operational amplifier increased slightly. Also, the out-put characteristics of the diode and the gate control of thyristor were normal. In this paper, the applicable posibilities of the electronic devices under the high hydrauric pressure are indicated on many trials.
