Title: Frequency modulation circuit
Inventor: ITO TAKEO
IPC: H03C3/00
Filed: 1988-02-15
Abstract: PURPOSE:To obtain a stable operation even in composite modulation and non- modulation by varying the loop gains and time constants of two PLL means connected in series corresponding to the ON/OFF of the input of a modulation signal. CONSTITUTION:A reference signal generating means 10 oscillates a frequency signal which becomes reference, and outputs it to a first PLL means 20. In the case of turning ON the input of the modulation signal 2 for a frequency modulation circuit 100, the loop gain of the means 20 is decreased by a control means 40, and the time constant of a loop filter is increased. Simultaneously, the means 40 increases the loop gain of a second PLL means 30, and decreases the time constant of the loop filter, thereby, runout from a synchronism holding range due to the signal 2 can be prevented from being generated. On the other hand, in the case of turning OFF the input of the signal 2, by performing reverse control as in the case of turning ON the input of the signal 2, stable oscillation output signals can be taken out from the means 20 and 30. In such a way, it is possible to prevent the runout from the synchronism holding range from being generated even in the composite modulation and also, to obtain an output signal with a high C/N in the non-modulation.

Filed: 1986-02-20
Abstract: PURPOSE:To increase the throughput of the titled dehydrator by providing a beating arm oscillated by an oscillating means with a supporting shaft as the center to strike down the cake deposited on a rotor in the purging stage. CONSTITUTION:While a disk sector 1 rotating on the rotating shaft passes through the slurry in a slurry tank, the solid components in the slurry are deposited on the filter cloth 2 of the sector 1 by the negative pressure in the sector 1.

Title: Manufacture of dielectric film
Inventor: UEDA MICHIHITO
IPC: H01L21/316
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a dielectric film whose leakage current is little, as a manufacturing method of a dielectric film which is used as a capacitive insulating film of a memory cell. SOLUTION: When a BST(barium strontium titanate) film 17x containing carbon compound 25 is heat-treated, the heat treatment is performed at a temperature, e.g. of 700 deg.C wherein elimination of the carbon compound becomes active. Thereby BST can be crystallized while the carbon compound 25 in the BST film 17x is eliminated. In particular, by increasing the rate of temperature rise up to a retaining temperature, the carbon compound 25 can be effectively eliminated from the BST film 17x, before the carbon compound 25 becomes hard to be eliminated on account of crystallization of BST. Thereby a BST film as a dielectric film of high permitivity which contains no carbon compound increasing leakage current can be formed.
