Title: Piezoelectric actuator
Inventor: WATANABE CHIHARU
IPC: H02N2/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent the displacement of a piezoelectric actuator from being smaller by depolarization by making the direction of polarization coincident with the direction of an impressed voltage by alternately repeating charging and discharging by impressing a switching voltage upon one side of a plurality of piezoelectric ceramic layers. SOLUTION: In order to polarize X two piezoelectric ceramic layers 10 stuck to each other without through any piezoelectric inactive shim material composed of a metallic plate, etc., a DC voltage Y impressed upon the upper and lower piezoelectric ceramic layers is alternately repeated by switching actions within the range of a coercive voltage which dissipates polarization at a voltage higher than a polarization voltage. In a polarizing state, a bimorph-like stroke which elongates against a positive electric field and contracts against a negative electric field is obtained.  When the charging and discharging of charges are alternately repeated, the initial displacement of a piezoelectric actuator can be secured without causing degaussing (demagnetization) and the actuator can cause bending displacement even when one side is not elongated and the other side is not contracted, because the direction X of polarization coincides with the direction Y of voltage. Therefore, the actuator can obtain double displacement in the vertical direction and is not forced into shutdown.

Title: Local oscillation circuit
Inventor: SAKAMOTO NORIYUKI
IPC: H03B5/20
Filed: 1984-12-06
Abstract: PURPOSE:To obtain easily two pairs of oscillation circuits by making use of the switching actions of a diode to perform switching of a padding capacitor and an oscillation coil. CONSTITUTION:When band switches S1-1 and S1-2 are set at positions as shown in the figure, a DC current supplied from +B flows in a route (a) to turn on a diode D2 and off a diode D1. Thus a resonance circuit is formed at a variable capacitor VC1 with a padding capacitor C3, the diode D2 and an oscillation coil L2. Then the DC current flows in a route (b) when both band switches are changed over. Thus diodes D1 and D2 are turned on and off respectively and therefore a resonance circuit is formed at the capacitor VC1 with padding capacitors C2 and C3 and an oscillation coil L1. In such a way, two pairs of oscillation circuits are obtained easily.

Abstract: PURPOSE:To detect remaining quantity of ink without fail by providing a flexible piezoelectric sheet which is fixed on an end face of the sidewall of an ink passing chamber and blocks an opening so as to detect the remaining quantity of the ink by an output voltage of the flexible piezoelectric sheet. CONSTITUTION:During the time where there is enough ink in an ink bag 5, the pressure of the ink in a flow passage is almost constant, a first ink passing chamber 2a is also filled with ink, and a flexible piezoelectric sheet 11 bends to the outside in an expanding way. A voltage is generated by the deflection. The voltage is detected through leads 12a and 12b and the presence of enough ink can be detected. When the ink in the ink bag 5 runs out, the ink in the first ink passing chamber 2a also decreases, the flexible piezoelectric sheet does not bend, and the voltage is not generated. When the ink decreases further, a negative pressure generates in the first ink passing chamber 2a and the flexible piezoelectric sheet 11 bends to the inside. At this time, a voltage with a pole reverse to the time when it is bent to the outside is generated. A running out of the ink can be detected by detecting this voltage.
