Title: Preparation of magnesium fluoride powder
Inventor: SHIBATA YUTAKA
IPC: C01F5/28
Filed: 1989-11-28
Abstract: PURPOSE:To prepare magnesium fluoride powder useful as a low refractive index filler by adding hydrofluoric acid to a cation exchange resin exchanged with Mg and subsequently separating the resultant MgF2 particles from the reaction system. CONSTITUTION:Hydrofluoric acid is added to a cation exchange resin exchanged with magnesium and the produced magnesium fluoride particles are separated from the reaction system to provide the objective magnesium fluoride particles. The preparation method permits to readily separate the produced superfine particles from the reaction system by accompanying the particles with the flow of water because the simultaneously produced impurity is the solid ion exchange resin of coarse granules and the objective substance MgF2 is the superfine particles in spite of the production thereof by the chemical reaction. The method further allows to readily prepare the MgF2 superfine particles useful as a filler employed from reflection-preventing films reducing the reflection of outer light and heightening the transmission of light in lenses while holding the diameter of the superfine particles.

The recording layer is composed of an organic polymer resin, an organic monomer substance having low melting point, and an organic monomer substance having high melting point and brought into transparent and cloudy states, respectively, when it is heated to transparent point and cloudy point, respectively, and cooled down to the room temperature. The card 36 is inserted and the optical density at the cloudy background of the anti-forgery pattern is measured at a cluodiness detecting section 31. The anti-forgery pattern is then heated up to the transparent point by means of a transparent hot stamp 32 and before the optical density is detected at a transparency detecting section 3. Validity of the card 36 is decided based on two optical density data and a forgery is returned back as it is. Magnetic information is operated by a magnetic head 35 for a genuine card and the pattern is heated up to the cloudy point by means of a cloudy hot stamp 34 thus recovering the cloudy state.

Title: Differential amplifier circuit
Inventor: NAKA NAOAKI
IPC: H03F3/45
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a differential amplifier circuit which enables the receiving even when small-amplitude differential input signals fluctuate by suppressing the reproduction of the output signal level fluctuation due to the manufacturing variance. SOLUTION: In a differential amplifier circuit having such a pair of input MOS transistors N1 and N2 that inputs are supplied to their gates and load circuits are connected to their drains, and then, current sources I1 are connected to their current sources, the fluctuation of the output level generated at the drain terminal n1 of each input MOS transistor is suppressed by changing the current value of each current source I1 in an interlocking way with the characteristics variance of the transistor.  For that reason, a current source circuit which decreases the current value of the current source I1 when the characteristics of the transistor vary due to the manufacturing process in such a way that the current driving ability of an N-channel transistor becomes higher and increases the current value when the characteristics vary in such a way that the current driving ability becomes lower. The output level of the drain terminal n1 is decided based on the ratio of the impedance of load circuits L1 and L2 to that of the input transistors N1 and N2. Therefore, when the current driving ability of the N-channel transistor becomes higher and its impedance drops, the decline of the output level is suppressed by decreasing the current value of the current source I1.
