Title: Voltage controlled oscillating circuit
Inventor: OMORI HIDEKI
IPC: H03B5/32
Filed: 1984-12-24
Abstract: PURPOSE:To prevent the impossibility of discrimination even if an input voltage is varied, by varying a bias voltage of a diode which is installed in a resonance circuit, in the forward direction or the reverse direction by the variation of a voltage inputted from the outside of the circuit, and switching the oscillation frequency. CONSTITUTION:A voltage controlled oscillating circuit (VCO circuit) 11 is provided with a resonance circuit which has been constituted of a vibrator 2, capacitors 3, 4 and 12, and a diode 13, and a DC voltage 7 of two levels corresponding to '1' or '0' is inputted from a logical circuit 6. The electrostatic capacity of the diode 13 is small, when it has been biased in the reverse direction, and large, when it is biased in the forward direction, and its variation quantity if large, therefore, by switching the direction of the bias, the diode 13 is operated as a switch. Accordingly, when the diode 13 is biased in the forward direction, the oscillation frequency becomes a low level, and when said diode is biased in the reverse direction, said frequency becomes a high level, and switching of the level is executed irrespective of whether the DC voltage which is inputted is large or small.

Abstract: PURPOSE:To prevent the yellowing of a base over the lifetime of a fluorescent lamp without any loss of safety by making a discharge tube holding base piece from PBT resin not containing a flame retardent and making a terminal pin fitted base piece from PBT resin containing a flame retardent. CONSTITUTION:A discharge tube holding base piece 12 is made from glass fiber reinforced polybutylene terephthalate(PBT) resin not containing a flame retardent, and a terminal pin fitted base piece 13 made from glass fiber reinforced polybutylene terephthalate resin containing a flame retardent. Namely, even if a temperature near electrodes 8 and 9 rises up to a hundred and several tens degrees during the lighting of a fluorescent lamp, the base piece 12 can be prevented from yellowing throughout the lifetime of the lamp, because of the use of PBT resin not containing a flame retardent. Also, even if an accident such as shortcircuiting should occur in a base 11, there is no danger of a fire because of the use of PBT resin containing a flame retardent for the terminal pin fitted base piece 13. And the yellowing of the base can be prevented even in the long term use thereof.

Abstract: PURPOSE: To obtain a chip piezoelectric component which is well sealed and superior in aging resistance and has spurious vibrations suppressed by coating a piezoelectric element plate and parts, including end surfaces of sealing plates on both surfaces of the piezoelectric element plate, with resin. CONSTITUTION: A flat plate upper sealing plate 4 and a lower sealing plate 8 provided with a gap part 5 are laminated on both surfaces of the piezoelectric element plate 1 which has a vibration electrode 2 and a lead-out electrode 3 on both surfaces. Then the piezoelectric element plate 1 and part or the whole of the end surfaces of the sealing plates 4 and 8 laminated on both surfaces of the piezoelectric element plate are coated with resin. The chip piezoelectric component which is thus obtained is well sealed and superior in aging resistance and has spurious vibrations suppressed, so the influence of the spurious vibrations on the frequency characteristics can be reduced. Therefore, the reliability when the element is reduced in size can be improved.
