Title: Operation detector for converter
Inventor: NAKAZAWA KATSUNORI
IPC: G04D7/12
Filed: 1987-05-15
Abstract: PURPOSE:To enable stable detection regardless of the magnitude of magnetic fluxes by converting the magnetic flux generated from a bipole converter of a hand type electronic watch to an analog electric signal, holding and voltage- dividing the max. value of the electric signal and setting a suitable reference value. CONSTITUTION:An electromotive voltage is generated from the magnetic flux generated in a sensor coil 9 from the magnetic flux generated from the bipole converter of the hand type electronic watch. The electromotive voltage from the sensor coil 9 increases and the voltage stored in a capacitor 10 for charging increases as well if the magnetic flux generated from the bipole converter is large. The threshold value in a comparator circuit 4 increases similarly as well. The electromotive voltage from the sensor coil 9 decreases and the voltage stored in the capacitor 10 decreases as well if the magnetic flux generated from the bipole converter of the hand type electronic watch is small. The threshold value in the circuit 4 decreases similarly as well. Since the threshold voltage fluctuates with the magnitude of the magnetic flux generated from the bipole converter in such a manner, the stable detection is enabled regardless of the magnitude of the magnetic flux.

Title: Optical pickup
Inventor: NAKAMURA TOORU
IPC: G11B7/09
Filed: 1979-09-14
Abstract: PURPOSE:To reproduce record on a record disk with simple constitution without contact by arranging long sides of a photodetector in parallel with the record disk and by dividing its photodetection surface into two with its diagonal line. CONSTITUTION:Beam focused via condenser lenses 5 and 5' are slantingly incident to record modulated-groove walls 6 and 6'. Reflected light beams from record modulated-groove walls 6 and 6' never return to condenser lenses 5 and 5', but are incident directly to photodetectors 7 and 7'. Their light spots move on two separate photodetectors according to changes in direction of reflected beams based upon modulated-groove wall surfaces. In this case, two outputs of photodetectors divided into two with the diagonal line are applied to subtracter 8 to obtain a difference signal, which corresponds to a difference in the quantity of light resulting from the movement of light spots on photodetectors. In other words, changes in angle of record modulated-groove wall surfaces can be detected and a sound signal is obtained. This constitution provides the contactless reproduction of a record disk with simple structure.

Writing and reading to and from memories 3 and 7 are done alternatively by S8 and during this, the antenna turns around and reading R is done by S11. Function generator 8 causes analog gate 5 to output a signal equivalent to the beam strength at the time of thetaT-thetaA utilizing distance memory signal S14 for the time equivalent to the radar transmission pulse width. Output signal S22 has the amplitude equivalent to the azimuth difference of an artificial echo and its generation point depends upon the distance data and azimuth. Displaying S22 makes an echo with the brightness and shape similar to the real one appears.
