Title: Base line stabilizing circuit
Inventor: HAYASHIDA SHINICHI
IPC: G01R19/00
Filed: 1990-10-15
Abstract: PURPOSE:To suppress the change of the level on an output signal line accompanying ON/OFF by symmetrically providing capacitor, resistors and switch elements on a feedback connection line with respect to an input terminal and synchronously subjecting both switch elements to continuity and discontinuity control. CONSTITUTION:A condenser 3', a resistor 4' and an FET 8 are provided on the side of the feedback connection line of an operational amplifier 1 and connected so as to become symmetric to the constitution on the side of an input terminal where a condenser 3, a resistor 4 and an FET 8 are arranged. The FETs 8, 8' are used as switch elements. When a pulse is supplied to the input terminal 2, the FETs 8, 8' are together turned ON but a signal is sent to the FETs 8, 8' through a control signal line, the moment the pulse is supplied to turn the FETs 8, 8' OFF. A change is generated accompanying ON/OFF of the FETs 8, 8' but, since the FETs 8, 8' are respectively arranged on the mutually reverse polarity sides of an amplifier 1, the change is set off. Therefore, no change is generated on an output signal line accompanying ON/OFF. As a result, no error is almost generated in the peak of the output pulse of a stabilizing circuit.

Title: Dome type piezoelectric speaker
Inventor: KISHI KANENORI
IPC: H04R17/00
Filed: 1985-12-10
Abstract: PURPOSE:To obtain a flat and thin speaker by interposing a viscoelastic layer in the neighborhood of the center of gravity in a piezoelectric diaphragm, and energizing a radiant sound pressure by executing a curved deformable vibration to a dome type vibration radiator with a vibronic force from the outer edge part of a piezoelectric vibration element formed by the coupling of a weight. CONSTITUTION:When a signal voltage (e) is impressed on a terminal 11, a piezoelectric diaphragm 2 generates the curved deformable vibration due to a piezo electric effect, however, since a piezoelectric vibration element constitutes a variable impedance element consisting of the couple of a weight 4 in the neighborhood of center of gravity in the piezoelectric diaphragm 2 interposing a viscoelastic layer 3, the movement of the center part of the piezoelectric diaphragm 2 is restrict corresponding to an oscillation frequency, and as a result, the piezoelectric diaphragm 2 performs the curved deformable vibration. At such a time, at a displacement point 5a corresponding to a curved displacement d0, the radium of the piezoelectric diaphragm 2 contracts by DELTAdelta, and therefore, a dome type vibration radiator 6 is deformed as shown in dotted line 6a, and the radium of curvature is made shorter than an original radium, and the radiator 6 swells in an upper direction. As a result, a curved displacement da is increased a little than the d0, the amplifying function of amplitude can be obtained.

Abstract: PURPOSE:To continuously operate a work for many hours and safely obtain nitrogen trifluoride at a low cost, by liquefying and concentrating the nitrogen trifluoride formed in production thereof in the coexistence of the specific third component gas in liquefying and concentrating the nitrogen trifluoride. CONSTITUTION:Given amounts of acidic ammonium fluoride and hydrogen fluoride are charged into an electrolytic cell 12 and electrolyzed while introducing a carrier gas 20 (e.g., N2 gas) to form NF3. The resultant NF3 gas 24 containing the carrier gas is then passed through an HF removing device 31, introduced into a collection vessel 1 and cooled with a refrigerant 11. Liquefaction and concentration of the NF3 are subsequently carried out while introducing the third component gas 3 (e.g., He gas) having a lower boiling point than that of the NF3, N2 and carrier gas without compatibility with the NF3 into the collection vessel 1. Thereby, since the third component gas is introduced, danger of explosion can be eliminated and continuous operation can be stably performed for a long period.
