Title: Plo device
Inventor: IKEBE HIROJI
IPC: H03L7/10
Filed: 1995-03-15
Abstract: PURPOSE: To eliminate the need to switch a center frequency by generating a reference clock with a fixed DAC control signal from a RAM which is previously set by utilizing a state wherein the signal is within the permissible range of the clock follow-up performance of a VCO. CONSTITUTION: The center frequency of the reference clock generated in the VCO 3 is determined by a DAC control signal 107 as a value stored previously in a RAM 8. When it becomes evident through previous inspection that the set value of the signal 107 deviates from the center value of all zones owing to variance of elements on a circuit, etc., a CPU 7 varies the value of the signal 107. Consequently, not is the center frequency of the reference clock in the VCO 3 switched by outputting a different signal 107 from the CPU 7 for each zone, but the reference clock signal 104 is generated with a constant signal 107 which is common to all the zones within the permissible range of the follow-up performance of the clock of the VCO 3.

Title: Driving method of piezoelectric element
Inventor: ISHIDA HISANORI
IPC: H02N2/00
Filed: 1990-03-06
Abstract: PURPOSE:To apparently eliminate the hysteresis of a piezoelectric element and to unequivocally decide the displacement by a voltage applied to the piezoelectric element by a method wherein, after the voltage applied to the piezoelectric element has been set to a minimum voltage or a maximum voltage which is used to drive the piezoelectric element, a desired voltage between the minimum voltage and the maximum voltage is applied and the piezoelectric element is driven by a prescribed displacement portion. CONSTITUTION:A minimum voltage and a maximum voltage which are applied to piezoelectric element are designated as Vmin and Vmax, respectively. When a voltage is increased monotonously like Vmin V1 Vmax or Vmax V1 Vmin or it is reduced monotonously from Vmas, voltage-displacement characteristic curves become A C B and B D A , respectively, and the displacement of the piezoelectric element corresponds to the applied voltages in a one-to-one manner. Consequently, when the voltage is set to Vmin before the driving voltage V1 is applied to the piezoelectric element, the displacement becomes XC; when the voltage is set to Vmax, the displacement becomes XD.

Title: Magnetic foreign material detector in non-magnetic wire or rod
Inventor: OOTAHARA YUUZOU
IPC: G01N27/72
Filed: 1978-05-13
Abstract: PURPOSE: To eliminate noise accompanying with vibrations of a wire and perform normal detection by providing the two differentially connected detecting coils inserting onto a non-magnetic wire or rod in a DC magnetic field and enclosing the circumference of the above-mentioned wire or rod with a sleeve on the inner side of the coils.  
     CONSTITUTION: Coils a, b are wound to a common winding frame 6 and are differentially connected. The circumference of a non-magnetic wire or rod 2 is enclosed by a sleeve 7 composed of copper and is disposed to the inner side of the winding frame 6. When the coils a, b exist in a DC magnetic field H 0  and the magnetic field H 0  changed by ΔH in the wire 2, eddy current i flows in the direction of generating such a magnetic field which generates this. This current is induced in the coils a, b. If, however, there is a conductor 7 around the wire 2, the change in the magnetic field owing to the above-mentioned eddy current i causes the eddy current corresponding to the conductive sleeve 7 to flow, as a result of which the magnetic change quantity on the outside circumference of the sleeve 7 becomes lower than that when there is no conductive sleeve 7. In other words, shield effect markedly appears. Namely, the noise owing to the vibrations of the wire is considerably reduced.
