Title: Microcapsule containing inorganic colloid and method for its production
Inventor: JIERII MOI
IPC: B01J13/02
Filed: 1992-10-23
Abstract: PURPOSE: To obtain a microcapsule having a controlled size, a narrow size distribution and restricted shell wall permeability by using inorganic colloidal particles. CONSTITUTION: Hydrophilic filling materials are dispersed and maintained as discrete droplets in an aqueous solution of a water soluble polymer comprising colloidal inorganic particles having a <=0.03 μm average diameter. The filling materials are inert towards the prepolymer and subsequent polymerization products. The colloidal inorganic particles have a surface energy such that the particles selectively position themselves at an interface between the lipophilic filling materials and the aqueous solution. An aqueous slurry of microcapsules having shell walls with the colloidal particles incorporated in the shell walls is obtained by polymerizing the prepolymer solution. The obtained microcapsules have a 50% volumetric diameter ranging between about 3-12 μm.

Filed: 1990-10-24
Abstract: PURPOSE:To detect the breaking of a wire even in ultrasonic wedge bonding conducting no ball-up of the wire by converting the quantity of displacement of the sinking of an ultrasonic horn due to the crush of the wire into voltage by a displacement sensor and deciding the presence of the wire from voltage difference before oscillation and after oscillation. CONSTITUTION:A horn 2 can be rocked around a support shaft, and vibrated by an ultrasonic vibrator, and a wire 5 is joined by the wedge 1 of one end. A displacement sensor 3 is mounted at a fixed distance on the other end of the horn 2. When the wire 5 is contact-bonded through an ultrasonic oscillation method, the wire 5 is crushed, the height of the wedge 1 is changed from (a) to (c), and the distance (d) of the displacement sensor 3 and the horn 2 is turned into (d). The distance (b) corresponds to voltage Vb and the distance (d) to voltage Vd, and the presence of the wire is decided on Vb--Vd>0(V). Since no (a), (c) changes due to the crush of the wire and b=d holds on the absence of the wire, Vb-Vd=0(V) holds, and the absence of the wire is judged.

Title: Rectifying and smoothing circuit
Inventor: HIGUCHI YOSHIO
IPC: H02M7/06
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items while enhancing power factor by placing a correcting resistor for reducing phase delays in currents which occurs in an inductor, in parallel with the inductor which increases a period for which the current is passed through a rectifying diode in the unit cycle of a commercial power supply. SOLUTION: Alternating-current input terminals of a diode bridge 2 for half-wave and full-wave rectification are connected to a pair of commercial power lines 5, 6 of a commercial power supply 1, and an inductor L and a correcting resistor R are connected in parallel with the commercial power line 5, respectively. The inductor L functions so that the inductor increases a time period for which a current is passed through the diode bridge 2 in the unit cycle of the commercial power supply 1, thereby improving the power factor. With the correcting resistor R connected, the maximum value for voltage produced across the terminals of the inductor becomes almost equal to the maximum voltage across terminals when the correcting resistor R is not connected, in spite of the current passing through the inductor L being reduced.  As a result, the power factor is enhanced by increasing the period, during which a current is passed through the diodes and reducing the phase delay.

In this case, for example, the transmission stations 5a, 5b receive normally a data from the transmission line 3 and the station 5c indicates a fault. Then the switch 15a is turned on and the switch 15b is turned off, then the data is sent from the transmission line 1 to each of transmission stations 5a-5b and the transmission stations 5a, 5b receive normally the data from the transmission line 1 and the reception station 5c indicates an abnormality. Thus, wiring mistake is surely detected and the deterioration in the function of the system is avoided.
