Title: Driver for piezoelectric elements
Inventor: NAKAMURA KAZUTO
IPC: H01L41/09
Filed: 1991-11-15
Abstract: PURPOSE:To increase reproducibility of displacement quantity of a piezoelectric element with respect to the driving voltage, by eliminating the influence of hysteresis of the piezoelectric element, and then to increase efficiency in utilizing energy of a driver for the piezoelectric element. CONSTITUTION:A diode 4 and a capacitor 5 are connected, in series, to an input terminal 1a for driving voltage. A piezoelectric element 2 is driven by charging voltage of the capacitor through an amplifier for driving 6. A discharging circuit 8 is connected to the high voltage side of the capacitor. A comparator circuit 18 detects whether the diode 4 is forwardly biased or reversely biased. When the comparator circuit judges that the diode is forwardly biased, it puts the discharge circuit 8 on. When driving voltage is higher than the charging voltage of the capacitor 5, the capacitor 5 is charged to the level of the driving voltage. When the driving voltage is lower than the charging voltage of the capacitor 5, the capacitor 5 is charged again to the level of the driving voltage after it has been discharged completely with the discharging voltage on.

IPC: H04N5/782
Filed: 1990-11-30
Abstract: PURPOSE:To delete a commercial message(CM) at a videotaping operation by a method wherein the title apparatus is controlled by using an output from a signal discrimination means which discriminates a digital signal other than a video signal and a sound signal which are superposed on a television(TV) broadcasting signal and which converts the digital signal into a prescribed data. CONSTITUTION:When, during a videotaping operation, a signal discriminator 3 detects and discriminates a signal indicating that the broadcast which is being received is a CM broadcast, a instant stop request signal is output to a control circuit 4 from the signal discriminator 3. The control circuit 4 instructs a tape driving-system control circuit 6 to instantly stop a tape transport operation and a video head 7 temporarily interrupts the output to a sound head which is not shown in the Figure. After that, when the signal discriminator 3 detects and discriminates a signal that the broadcast which is being received has been changed over to normal broadcast, an instant stop release request is output to the control circuit 4 from the signal discriminator 3 and the control circuit 4 instructs the tape transport system control circuit 6 to start the transport operation of a magnetic tape 8 again. Thereby, it is possible to surely perform a videotaping operation which detects a CM while the CM is being broadcast.

Abstract: PURPOSE:To prevent a deterioration in image quality by forming a thin noble metal film such as platinum on an aperture plate by means of ion sputter coating or the like. CONSTITUTION:In an aperture device for determining an angular aperture of an electron beam applied apparatus, after an aperture plate 2 is subjected to heating (approximately 2000 deg.C) in a vacuum, a thin noble metal film 7 such as platinum is formed on a surface of the aperture plate 2 by means of ion sputter coating or the like.

IPC: G01P3/487
Filed: 1993-11-30
Abstract: PURPOSE:To detect and correct an optimum position for attachment so that the respective parts constituting the measuring instrument are held at proper fitting positions at all times. CONSTITUTION:An electromagnetic induction signal which is radiated from a transmission-side electromagnetic induction coil through magnetic flux and indicates the rotation of a wheel of a bicycle is detected as variation of a magnetic field at the periphery of a reception-side electromagnetic induction coil 26 and received by resonance with a tuning capacitor 41. This received signal is amplified by a detecting circuit 42 and outputted to a pulse processing circuit 43, and extracted as pulses, and the crest value T of the received signal waveform is outputted to a CPU 44. The CPU 44 performs an arithmetic process for the travel state of the bicycle on the basis of pulses of the received signal and displays it at a display part. Further, the crest value T detected by the CPU 44 becomes less than a specific value, it is evident that the transmission- side and reception-side electromagnetic induction coils shift in position, so the positions of the electromagnetic induction coils are changed and the positions for the attachment are corrected so that the detected crest value reaches the highest crest value.
