摘要： PURPOSE:To limit the amplitude of a quartz oscillator and to prevent defect of the quartz oscillator, by providing a hollow supporting frame at both ends of the quartz oscillator supported with a supporting wire made of one metallic fine wire. CONSTITUTION:After bonding one end of a supporting wire 2 made of a metallic fine wire with an electrode 3 of a quartz for 1 with bonding member such as solder, the wire is folded in parallel with the electrode 3 and along the center of broadwise direction of the quartz for 1. Another end of the supporting wire 2 is fixed with a conductor 8 formed with a frame of a hollow supporting frame 7 made of ceramic and synthetic resin with solder. Supporting frames 7 and 7' are almost symmetrically arranged to the center of lengthwise direction of the quartz for 1, and they are bonded with a terminal of a board 5 and one end of the supporting frames 7 and 7' with solder. Thus, even if the quartz for 1 is oscillated due to external shock, the amplitude of the quartz for 1 is limited at the inside of the supporting frames 7 and 7'.

摘要： PURPOSE:To obtain wide-band characteristics with low impedance by arranging two piezoelectric ceramic plates in the lengthwise direction of an inflection oscillation transducer and at right angles to the displacement direction while their residual polarization directions are opposite. CONSTITUTION:Between constantly elastic metallic plates 10 and 11 made of ironnickel alloy, piezoelectric ceramic plates 13 and 14 performing thickness slide oscillation are sandwiched in parallel, while their residual polarization directions 15 and 16 are opposite, and connected together being soldered. The electrode parts 17 of the piezoelectric ceramic plates 13 and 14 are edged to prevent short circuits with the metallic plates 10 and 11. Then, a lead wire from one electrode part of the ceramic plate 13 and another lead wire from one electrode part of the ceramic plate 14 are short-circuited into a lead wire 18 and when an AC voltage applied between it and a lead wire 19 from the common electrode part of the two ceramic plates, slide oscillations are performed by the ceramic plates as shown by arrows 20 and 21, so tht the transducer performs inflection oscillation as shown by dotted lines.

摘要： PURPOSE:To form a polarized mechanical filter, by using the mechanical oscillators of the same oscillation type and at the same time distributing all connectors right- angled to the oscillators. CONSTITUTION:The main connector 20 that performs a vertical oscillation to give an in-phase connection among the mechanical oscillators 17-19 plus the interlacing connector 21 that connects the oscillators 17 and 19 is opposite phase to each other through a vertical oscillation are connected right-angled to the oscillators 17-19 that perform the primary oscillation in a retrogressive oscillation type. In other words, a pair of mechanical oscillators 17 and 19 are formed with a lengthwise shift each to the mechanical oscillator to realize an attenuation pole. As a result, the connectors 20 and 21 can be connected successively and in parallel to each other on the same plane and nearly vertically to the mechanical oscillator.

摘要： PURPOSE:To improve the spurious characteristic sufficiently, by providing an antiresonant circuit including the element of series arm of the electric filter to cause the frequency of the antiresonant circuit to coincide with the spurious frequency approximately due to higher oscillation of the mechanical filter. CONSTITUTION:Single capacitor CS1 is connected in parallel to the series arm (the series connection circuit of L1 and C1) of one filter of electric system FE to cause the resonance frequency of the parallel circuit shown by arrow fS1 to coincide with spurious frequency f1 approximately. Consequently, the overall frequency characteristic becomes C, and the characteristic in frequency f1 is improved sufficiently.
