Filed: 1979-02-22
Abstract: PURPOSE:To secure the clock regeneration for the demodulator via the divider circuit plus the simple circuit which is required to reset the divider circuit, by selecting previously the carrier frequency to be the integer-fold value of the clock frequency. CONSTITUTION:Divider circuit 18 is connected to the output of voltage control oscillator 14. And if the frequency of the carrier features n-times as much as the clock frequency, the frequency component of the clock emerges at the output through the 1/n division of circuit 18.

Title: Electron microscope
Inventor: KUBOZOE MORIKI
IPC: H01J37/10
Filed: 1985-02-05
Abstract: PURPOSE:To enable magnification of a lens to be changed without changing the direction of an image by focusing an image from the proceding lens on the position of principal plane of a certain lens and changing excitation currents for the lenses other than the lens by which an imiage is focused on its principal plane. CONSTITUTION:Magnification (M) in an electron microscope is expressed by a given formula. The second intermediate lens 7 does not contribute to the magnification but since it is excited, the excitation simply rotates the image around the optical axis 14. The image can be, therefore, rotated without chang ing the magnification by changing the excitation of the second intermediate lens 7. The magnification can be changed without rotating on of the image by equalizing the polarity of the first intermediate lens 6 to that of the first projecting lens 8, changing the polarity in the second projecting lens 9 to the opposite one and maintaining the total of changes in excitation of the three lenses almost zero. With this constitution, the image can be rotated around the optical axis, trimming of a visual field is carried out almost instantaneously, thereby the efficiency in the micoscope is extraordinarily improved.

IPC: H02N2/00
Filed: 1994-02-18
Abstract: PURPOSE:To drive an ultrasonic motor without remarkably causing audible sound even when the detection signal is over a specified level, when audible sound occurs in an ultrasonic motor. CONSTITUTION:The detection signal outputted from a sensor electrode 26 is rectified with a diode 32, and is inputted as a signal VB into an operational amplifier 38 after being divided with resistors 34 and 36. A capacitor 42 is charged, if the voltage level of the signal VB is higher than the voltage across it, and is discharged gradually through a resistor 44 if lower. The voltage across this capacitor 42 is inputted into an integrating circuit as a signal VC through an operational amplifier 48. For the signal VC, if the waveform of the detection signal falls into disorder, the voltage level goes up even if it is over the specified level of the detection signal is very short. In the integrating circuit, if the voltage level of the signal VC is higher than the reference voltage VS, it raises the oscillation frequency of VCO56, so in the case that the waveform of the detection signal falls into disorder, the frequency of a drive signal is raised surely even if the detection signal is over the specified level for a short time.
