Title: Treatment of suspension
Inventor: OOSHITA NAOJIROU
IPC: B01D21/01
Filed: 1978-12-26
Abstract: PURPOSE: To solidify stably suspension without consuming a large amount of water and spending much time and labor by adding powders composed of a mixture of cement or calcium and powdery macromolecular coagulant to the suspension.  
     CONSTITUTION: Powders composed of a mixture of cement or calcium and powdery macromolecular coagulant are added to suspension in water treatment. The mixture is stirred. Cement or calcium is dispersed into the suspension. Calcium including that contained in the cement act on interfacial potential of suspended matter. The suspended matters form flocks by weak cohesive force. When the stirring is continued, the macromolecular coagulant is easily dissolved without coagulation in a fisheye form and is converted to coarse flock having strong physical strength, wherein a nucleus is composed of cement or calcium hydroxide. The flock is completely separated from water and precipitated. The precipitated sludge has good dehydrating property and is easily solidified.

Title: Aging of electrolytic capacitor
Inventor: HARASHIMA MIKIO
IPC: H01G13/00
Filed: 1989-06-27
Abstract: PURPOSE:To shorten aging time and operate an electrolytic capacitor efficiently by irradiating the electrolytic capacitor with microwaves and performing aging in a state where the temperature of a capacitor element rises. CONSTITUTION:Direct current voltage is impressed to an electrolytic capacitor 1 to perform aging in a state where a magnetron 10 irradiates its capacitor with microwaves and the temperature of a capacitor element rises. Accordingly, molecules of a small quantity of water contained in electrolyte with which the inside of the capacitor element is impregnated rotate and collide by irradiating the electrolytic capacitor 1 with the microwaves. The inside of the capacitor 1 generates heat by friction resulting from the above rotation and collision of the molecules and then, its temperature rises. Consequently, direct current voltage is impressed to the capacitor 1 in accordance with the normal process and aging is performed. The aging of the capacitor 1 is thus conducted efficiently in a short while.

Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To quickly rise the output voltage with no limitation given to the drive when a power supply is applied by suppressing the base current of an output control transistor(TR) via a circuit operation control circuit when the input voltage is higher than a prescribed level. SOLUTION: A current amplification factor control (HFE) circuit 101 consists of a diode D2 which has its anode connected to the emitter of an output control TR Qout, i.e., an input terminal Tin together with its cathode connected to the connecting point between the collector of a TR Q5 and the emitter of a TR Q6 respectively. The D2 is equivalent to a circuit operation control circuit and controls the operation of the circuit 101 according to the input voltage Vin. In other words, the cross-mountain current control is suppressed by the current that is supplied from the side of the Vin through the D2 when the collector-emitter voltage of the TR Qout is higher than the forward voltage of the D2.

Title: Broad band aperiodic reception circuit
Inventor: MORI EIZO
IPC: H04B1/18
Filed: 1986-07-15
Abstract: PURPOSE:To stabilize the titled circuit by lowering an output impedance by means of drain-source feedback while employing the drain-gate feedback so as to suppress an antenna specific resonance characteristic. CONSTITUTION:Electromotive force induced in a 1st coil 2 wound on a ferrite rod 1, that is, an antenna coil, is fed to a gate of a FET 4. A coil 3 is a 2nd coil wound on a ferrite 1 and a signal current of a drain Af the FET 4 is given to the coil 3 to apply negative feedback. Simultaneously, the signal current of the drain is given to a transformer 15 to apply negative feedback to the source. In this case, since the quantity of the drain-gate negative feedback is increased more as the antenna impedance is higher, a remarkably large gain at the natural resonance frequency is suppressed and a voltage proportional to the antenna electromotove force is obtained in a load 5 as an output. Since the feedback to the source is active at the same time in this case, the output impedance is kept low.

Title: Liquid jetting head
Inventor: FUKUCHI HIROMICHI
IPC: B41J2/045
Filed: 1979-12-20
Abstract: PURPOSE:To prevent ink liquid in a jet chamber from flowing back into a liquid chamber, to improve easiness to produce drops of ink and to make possible a high speed recording by a method wherein a subsidiary jet chamber is provided between the jet chamber and the liquid chamber. CONSTITUTION:To take an example, when voltages are applied simultaneously between piezoceramic chamber 19-1 and 19-2 and between electrodes 20-1 and 20-2, a plate 17 is deffected in the form of two-dot chain line in the jet chamber 11 and the subsidiary jet chamber 12 and the internal pressure is increased. And, when the ink liquid 18 in the jet chamber 11 is discharged from a jet nozzle 10, the ink liquid 18 will flow back toward a chamber 15. On the other hand, ink liquid 18' also in the subsidiary jet chamber 12 collides with the flow back ink 18 to prevent both from continuing to flow because the former tends to run into the chamber 11 by the rise of the internal pressure. The easiness to produce drops of ink is improved by means of this action for stopping the reflux. EFFECT:Mechanical distortion of ceramic members becomes smaller and the shape can be smaller-sized.
