Abstract: PURPOSE:To increase separation speed of a specified component material and carry out the separation efficiently by using a liquid membrane having a liquid phase in which magnetic particles are dispersed. CONSTITUTION:Separation and extraction of aimed components are carried out easily using a liquid membrane having a liquid phase in which magnetic particles are dispersed, preferably combining with application of a magnetic field whose direction reverses to the liquid membrane. Fine particles of Fe3O4 coated with SiO2 or composite particles of ferrite and polymer are used as the magnetic particles. In the case that the liquid membrane phase is water phase, water is used as the liquid solvent in which the magnetic particles are dispersed and if necessary methanol, etc., which has high affinity with water, may be used. In the case that the liquid membrane phase is an organic phase, organic solvents such as benzene, etc., are used. The separation method involves bringing a mixture for separation into contact with one side of said membrane and bringing the other side of the membrane with another gas phase or liquid phase. Specified components moves to pass through the liquid membrane from the mixture and are separated to the other phase.

Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain a homodyne transmitter-receiver circuit which removes the influence of a modulation component in an oscillation signal and which removes the influence of a comb teeth-shaped noise generated by its high-frequency component in a frequency conversion output by a method wherein the output of an estimated-noise generated means by which a noise estimated to be generated in the output of a frequency mixing means is generated on the basis of the modulation signal of a frequency generation means is subtracted from the output of the frequency mixing means. SOLUTION: A signal which is received by an antenna 6 is passed through a circulator 5 so as to be guided to a frequency mixer 7. In the mixer 7, the signal is mixed with a local oscillation signal which is branched by a power distributor 4 so as to perform a frequency conversion. In addition, the output of a modulation-signal generation circuit 1 is supplied to a differential circuit 10 via a programmable filter 9, and its signal is subtracted from the output of the frequency mixer 7. A comb teeth-shaped noise which is generated in the output of the frequency mixer 7 is a noise in which a change in the DC level of a waveform containing a harmonic distortion similar to a modulation signal fm appears. Consequently, the output of the modulation-signal generation circuit 1 is filtered and level-adjusted so as to be subtracted from the output of the mixer 7.

Title: Halogenated silver photographic sensitive material
Inventor: HATAKEYAMA AKIRA
IPC: G03C1/32
Filed: 1991-11-05
Abstract: PURPOSE:To obtain a halogenated silver photographic sensitive material having good dryness after developing treatment by providing at least one layer taking urethane resin as a binder in a place farther away from a support body than a nonphotosensitive hydrophilic colloid layer. CONSTITUTION:A layer (polymer layer) taking urethane resin as a binder farther away from a support body than a nonphotosensitive hydrophilic colloid layer may be one layer or two or more layers. In this case, when the thickness of the polymer layer is too small, the water resistance of the polymer layer is insufficient and on the contrary, when the thickness of the polymer layer is too large, the steam permeability of the polymer layer is insufficient, causing the moisture absorption and removal of a hydrophilic colloid layer of a back layer to be hindered, making curling defective. Since the thickness of the polymer layer also depends on the physical properties of the binder used, it is determined in consideration of the two. That is to say, the thickness of the polymer layer is preferably 0.15-10mum, more preferably 1-5mum. depending on kinds of binders.

Title: Motor lock protective circuit
Inventor: INOUE TOMOHIRO
IPC: H02P7/288
Filed: 1990-10-26
Abstract: PURPOSE:To prevent smoking or firing and to facilitate designing by setting the locking time based on the capacitance of a capacitor and charging/ discharging current values and then performing ON/OFF control of current flowing into a motor. CONSTITUTION:When voltage drop across a resistor 4 for detecting motor current increases upon locking of a motor 1 and exceeds a reference voltage 6, output of a voltage comparator 5 is inverted and a High output is produced. A driving amplifier 9 controls the motor current based on the output from the voltage comparator 5 and settles the voltage drop across the resistor 4 at same level as the reference voltage 6. Since FG output disappears, a transistor 10 is turned OFF and when a capacitor 11 is charged from a constant current source 12 and the voltage thereof exceeds a reference voltage 14, output of a voltage comparator 13 is inverted and transistors 16, 17 are turned ON. Consequently, the voltage at a torque command terminal is forcibly pulled high and a transistor 2 is turned OFF thus cutting the motor current.
