Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a composite material useful in producing a ceramic filter or the like, its production method, and a ceramic porous body obtained by using the composite material. SOLUTION: A flexible slab foam produced by a normal method is cut into a sheet foam having a specified dimension and subjected to an explosion treatment to remove the cell membranes, and a binder is prepared by compounding an ethylene-vinyl acetate copolymer emulsion with thermally expansible microcapsules. The sheet foam is immersed in the binder at normal temperature for 1 min, taken out, and pressed with a calendar roll to press out a part of the binder. The sheet foam is then dried at 50 deg.C for 5 min to remove a part of water and heated at 140 deg.C, the thermal expansion temperature of the microcapsules, for 1 min to thermally expand the microcapsules to form hollow particles 1. Thus, the hollow particles 1 are bonded to each other and so are part of the hollow particles 1 to the foam backbone, giving the objective composite material.

Title: Power unit
Inventor: ISHIKURA HIROSHI
IPC: H02J1/00
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent the outflow of charge from a capacitor on input side caused by instantaneous power failure, while contriving the suppression of a rush current and the protection of a power unit against the reverse connection of an input terminal, in a DC input type of power unit which is equipped with a capacitor for charging on input side. SOLUTION: A rush current is suppressed in condition that the on-resistance of FETs Q1 and Q2 is increased by limiting the electrical continuity of the FETs Q1 and Q2 provided in an input line by detecting the rush current with a resistor R1 thereby turning on a transistor T1 at occurrence of a rush current. In case that the input terminals are connected, with reverse polarity, to the power source line, the FETs Q1 and Q2 are biased reversely, and are turned off to function as reverse checking diodes, so they prevent the power unit from breakage. In case that instantaneous power failure occurs, this power unit detects the discharge current, which has been flowing in the reverse direction by the discharge of a capacitor C1, with the resistor R1 in a discharge preventive circuit 11, and turns on a transistor T2 and turns off the FETs Q1 and Q2 thereby checking a discharge current.
