摘要： PURPOSE:To aim at high energy by multiple electric discharge so as to obtain the device of abundant practicality stated in the headline by arranging plural piezo-electric elements in series and providing electrodes on their side faces and by applying alternating voltage to one of the electrodes. CONSTITUTION:When alternating voltage of a predetermined frequency is applied to the positive terminal 601 of a connector 6 made of insulation resin and connected to a housing 15 of a housing cap 12 made of metal respectively, the voltage is applied to piezo-electric elements 1 through an electrode plate 7 and an electrifying spring 8. As a plurality of piezo-electric elements 1 of almost the same shape and having the same resonance cycle are connected together in series, each generated voltage is added to each other to become high voltage. Thus generated high voltage is applied to an electric spark gap between a central electrode 2 and a grounding electrode 3 through a thin plate disc 5, high voltage side electrodes 9, 10 and a seal glass 11, and spark is discharged. Then, high energy by multiple discharge can be obtained.

摘要： PURPOSE:To increase the usable temperature range by compensating the volume change of a sealing chamber due to linear expansion coefficient different of a casing and a piezoelectric element by the volume change of liquid in the chamber. CONSTITUTION:A piezoelectric element 1 is disposed in a casing 2, its one end is secured to a stopper 7, and the other end is contacted fixedly with a piston 8 to transmit the axial elongating or contracting displacement to the piston 8. Silicon oil is sealed in a space formed of the piston 8, and a bottomed cylinder 2a to form a sealing chamber 10. A through hole 12 of small diameter is formed by a piston 8 which communicates with the chamber 10 in the casing 2, and the rod 3 of an output member is slidably provided therein. The rod 3 is energized by a spring 4 supported by a stopper 9 to the chamber 10 side to apply a pressure to the oil. Thus, the volume change of the chamber 10 due to the difference of the linear expansion coefficients of the casing 2 and the element 1 is brought into coincidence with the volume change of the oil and compensated.

摘要： PURPOSE:To obtain a compact, long-life measuring device for fluid characteristics by forcing a piezoelectric oscillator provided in oil to oscillate, measuring the amplitude of the output signal of the piezoelectric oscillator and calculating the viscosity of the oil, and detecting the deterioration of the oil. CONSTITUTION:The piezoelectric oscillator 1 is inserted into the bottom part of the oil pan of an engine and put in the oil. A pulse generator 30C generates a pulse signal of frequency equal to the characteristic frequency of the oscillator 1, and its oscillation output is supplied to an electromagnetic coil 6 from a constant current circuit 30-D as an exciting signal through lead wires 6a and 6b to allow the oscillator 1 to oscillate according to the output. The output signal of the oscillator 1 is passed through lead wires 5a and 5b and converted by a differential amplifier 30E, rectifying circuit 30F, and smoothing circuit 30G into a DC signal proportional to the amplitude, and amplitude data A is obtained by an A/D converter 30H. The output signal of a temperature sensor 31 in the oil is converted by an A/D converter 30B into temperature data T, which is outputted. A main arithmetic circuit 30J reads the data T and A and the deterioration of the oil is detected on the basis of those data.
