Title: Phase synchronizing oscillator circuit
Inventor: FUKUKAWA SHINICHI
IPC: H03L7/093
Filed: 1990-08-28
Abstract: PURPOSE:To improve the power variance characteristic and the temperature characteristic to the oscillation frequency and to prevent step-out by providing a voltage limiting circuit and a limit voltage setting circuit. CONSTITUTION:The output signal of a voltage controlled piezoelectric oscillator 6 is inputted to a frequency divider 1 and has the frequency divided up to the frequency of a reference signal. The output signal of the frequency divider 1 and the reference signal are inputted to a phase comparator 2, and the phase difference from the reference signal is outputted as a pulse signal. A voltage limiting circuit 3 inputs the pulse signal, which has the peak voltage limited, to a loop filter 5 and smooths it to output a DC voltage signal proportional to the phase difference. Since the circuit 3 is set by a limit voltage setting circuit 4 so that it limits the peak voltage of the pulse signal, a maximum voltage of the pulse signal outputted from the comparator 2 is limited and outputted. Therefore, the variance in amplitude of the pulse signal due to the variance of power or temperature is reduced. Con sequently, the oscillation frequency characteristic is improved to prevent step-out.

Inventor: OKAYAMA YUKO
IPC: H04N19/625
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To provide an image coding method which codes an image so as to display all data on the resolution of the original image by reducing the image, burying the image groups having optional color information into the vertical and horizontal parts of the reduced image to secure the resolution of the original image, and coding an image that has the same size as the original image.

Title: Method and device for decontaminating radioactive metal wastes
Inventor: NISHIWAKI HITOSHI
IPC: G21F9/28
Filed: 1994-09-21
Abstract: PURPOSE: To prevent the reverse contamination of low-level contaminated wastes after the treatment of high-level ones by housing radioactive metal wastes inside a barrel, projecting an abrasive over the surface of the wastes while rotating the barrel to stir it and decontaminating the whole surface of the radioactive metal wastes uniformly. CONSTITUTION: Radioactive metal wastes W are supplied into a barrel 1 from a metal waste supplying container 2. While the wastes W are stirred by rotating the barrel 1 slowly, an abrasive is projected from an abrasive projecting machine 3 to conduct a dry blast decontamination. The abrasive, which is contaminated through the contact with high-level contaminated wastes, is returned to a hopper 9 of the abrasive projecting machine 3 by way of a high-level contaminated abrasive conveyor 7 and is recycled. When decontamination is continued for a prescribed time, the surface layers of the wastes W is gradually exfoliated together with radioactive substances adhering to them and the surface contamination density lowers. Then, a new abrasive is supplied to the hopper 9 and a dry blast decontamination is conducted by rotating the barrel 1 slowly in a similar way.  The abrasive is circulated through a low-level contaminated grinding agent conveyor 8 to reuse it.
