Title: Clock extract circuit
Inventor: ISHIHARA TOSHIO
IPC: H04L7/033
Filed: 1993-06-29
Abstract: PURPOSE:To reduce jitter of an output of a voltage controlled oscillator by connecting two stages of phase synchronization circuits in cascade and applying a jitter component extracted at the pre-stage to an automatic phase synchronization control signal in an opposite phase to the post-stage phase synchronization circuit. CONSTITUTION:A phase of an input clock signal 1 is compared with a phase of an output signal of a voltage controlled oscillator(VCO) 6 at a phase comparator 5 and its output receives a band limit at a low pass filter 7 and the result becomes an automatic phase synchronizing signal of the VCO 6. A phase locked loop circuit (PLL) 4 executes phase locking with an output of the VCO 6. In this case, a jitter reduction control circuit 12 inverts a jitter component included in the input signal of the PLL 4 and adds the result to an adder circuit 11 and interrupts an output of a phase comparator 8 thereby cancelling a jitter component in the automatic phase synchronization component applied to a VCO 9. A low pass filter 10 has a sufficiently wider band than the band of the low pass filter 7.

Abstract: PURPOSE: To enable making of transparent ice by constructing an ice making device out of an ice making tray divided into two tanks, the upper and the lower, by an intermediate partition plate having a plurality of holes and of an ice making shelf having a heating means such as a heater. CONSTITUTION: The bottom of an ice making tray 7' is heated by a heating means such as a heater and freezing is let to begin mainly from the upper side part of the ice making tray 7'. Thereby sequential freezing in one direction from the upper side to the lower of the ice making tray 7' can be brought about and relatively transparent ice is obtained in the tank above an intermediate partition plate 10. Since the freezing occurs last in the tank below the intermediate partition plate 10, besides, a gas content and impurities contained in water for making ice are frozen finally in the lower tank. Therefore they are confined in the ice and bring about cloudy ice. After completion of the ice making, the part of the transparent ice formed in the part of the tank above the intermediate partition plate 10 is used.
