IPC: H01B3/12
Filed: 1995-06-15
Abstract: PURPOSE: To reduce the dielectric loss, and improve the temperature characteristic by using a dielectric composition of a predetermined composition formula. CONSTITUTION: The powder obtained by mixing SrCO3 , CaCO3 , Nd2 O3 , TiO2 and MgO with a predetermined composition ratio, is calcined in the atmospheric air for example at 1,050 deg.C for a given time, then pulverized, and further calcined at 1,200-1,300 deg.C for a given time, to synthesize a solid solution having a perovskite structure. Then the synthesized powder is well pulverized, pressed and molded into a disc-shaped piece, and sintered in the atmospheric air at a given temperature. In this case, a composition formula (1-y)(Sr1-x Cax )TiO3 .yNd(Mg1/2 Ti1/2 )O3 in which x is 0.01-1.0, y is 0.3-0.6 is used. Whereby the temperature coefficient of the resonance frequency is ±60 ppm/ deg.C, the dielectric loss is reduced in situ, or by adding a small quantity of additives, and the temperature characteristic can be improved.

The main flow of the ink enters the bypaths 61, 62 and reaches the ink discharge port 60, while a small pulsating flow with its pressure reduced is directed into the passage 50. The passage 50 is filled up with the ink by, e.g., the attracting force of capillary action generated at a narrow gap between wire guides 52, 53. Further, the ink is drawn up to a printing end face of the wire 51 by the capillary action of a gap 54 between the outside peripheral surface of the wire 51 and a guide hole of the guide 52, whereas an excess ink is discharged via the discharge port 60 through an ink regulating and recovering groove 69. Accordingly, a constantly fixed amount of ink is supplied to the printing end face of the wire.
