Title: Digital filter circuit
Inventor: MORI HARUKUNI
IPC: H03H17/08
Filed: 1989-06-06
Abstract: PURPOSE:To prevent the scale of a circuit from being increased by multiplexing two color difference signals by double clocks in a digital video equipment, making the delay quantity of each tap of a filter double and obtaining an equivalent characteristic by one system of the circuit. CONSTITUTION:Two color difference signals (o) and (p) are inputted to a switcher 1. A switching signal (q) switches the signals (o) and (p) and the two color difference signals are alternatively multiplexed by the double clocks. The two color difference signals are multiplexed by the same clock period as a luminance signal and filter processing is executed. At such a time, since the two color difference signals are alternatively multiplexed, they are not mixed and arithmetic can be executed for each element. When such a result is separated, the same function as conventional function can be realized by one system. Thus, to the filter circuit of a high degree, the scale of the circuit can be prevented from being increased.

Title: Magneto-optic thin film photo circuit element
Inventor: OOTA YOSHINORI
IPC: G02F1/09
Filed: 1979-11-02
Abstract: PURPOSE:To obtain a nonantimetrical photo circuit element which is small in size, is stable and permits easy integration by selecting the widths etc. of two sets of optical guides provided to a magneto-optic substrate having Faraday effect at predetermined values and making the propagation phase constant of both guides equal. CONSTITUTION:An optical guide 3 and a thick and convex optical guide 4 of a shape are provided in proximity on a garnet substrate 1 having Faraday effect. If the widths W1, W2 of these optical guides 3, 4 are changed and are so selected that the propagation phase constants of the guides 3, 4 for TE mode light and TM mode light become equal, the equivalent refractive indexes of the guides 3, 4 become equal. Hence, the TE mode light propagated in the guide 3 by the Faraday effect owing to a magnetic field 7 cozes into the guide 4, where it is converted to the TM mode light, whereby photocoupling is accomplished. The TM mode light going reverse in the guide 4 does not couple to the TE mode light and propagates straightly in the guide 4. With this constitution, the nonantimetrical magneto-optic thin film photo circuit element becomes small in size, stable and easy to integrate.
