Title: Treatment of inorganic oxide
Inventor: SUZUKI TAKEO
IPC: C01G23/00
Filed: 1988-10-17
Abstract: PURPOSE:To efficiently disperse inorg. oxide particles in a fluorine-based solvent without the particles being flocculated and to improve the water repellency and chemical resistance of the surface of the oxide by heating the oxide in the presence of a fluorinating agent and water. CONSTITUTION:Any well-known inorg. oxide can be unrestrictedly used as the inorg. oxide. The oxide of a group III metal such as LiO2 and the oxide of a group IV metal such as SiO2 can be exemplified. When the oxide consists of silica and the metal oxide, the content of the silica is controlled to >=50wt.% or preferably to >=80wt.%. The oxide is heated in the presence of a fluorinating agent such as HF and NaF and steam. The heating temp. is controlled to 100-300 deg.C or especially to 150-250 deg.C. As a result, the F atom introduced into the oxide is replaced by the OH group on the oxide surface, and firmly combined with the metal atom, and excellent affinity for a fluorine-based solvent or a fluororesin is exhibited.

Title: Data transmission circuit
Inventor: MATSUMOTO ATSUHIKO
IPC: H04B5/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a data transmission circuit based on electromagnetic coupling by which data are transmitted without error with a simple configuration. SOLUTION: A parallel-connected diode 22 and a capacitor 27 are connected between a terminal 21a of a reception coil 21 and a ground level point GND, and when a positive electromotive force is induced at the terminal 21a by electromagnetic induction from a transmission coil 16, a short-circuit current flows to the capacitor 27. The short-circuit current produces an electromotive force in the transmission coil 16 by mutual induction between the reception coil 21 and the transmission coil 16 and a high electromotive force is momentarily induced at the terminal 21a. Thus, a voltage higher than that without the capacitance 27 is outputted at an output terminal 24. The operation is similar when a positive electromotive force is induced at a terminal 21b and a reception signal with a high level is outputted at the output terminals 24, 25 by capacitors 27, 28.

Title: Vibration insulator for optical system
Inventor: SATO HIROTA
IPC: G03B17/00
Filed: 1989-10-04
Abstract: PURPOSE:To attain correct vibration insulation from immediately after actuator operation is started without generating ringing by allowing the timing of starting of an actuator operation to accord with when a shaking vibration speed is zero. CONSTITUTION:A vibration insulator is provided with an actuator operation starting timing means 22 actuating an ultrasonic motor 120 as an actuator driving an optical system in a direction deadening the shaking vibration of the optical system when the shaking vibration speed becomes zero after the input of a signal starting shaking vibration preventing action. Therefore, by allowing the timing of starting of the actuator operation to accord with when the shaking vibration speed is zero, the need of rapid accelation is eliminated and accelation is gradually carried out according to the accelation of the shaking vibration speed. Thus, the correct vibration insulation can be attained from immediately after it is started without generating the ringing.
