Title: Filter
Inventor: TANIGAWA MASANOBU
IPC: B01D39/16
Filed: 1994-08-31
Abstract: PURPOSE: To improve regeneration efficiency of a thread- and wire-coiled filter of a filtering body produced by coiling cotton threads and shape memory alloy wires together by heating filtering body to the temperature higher than the transition temperature of the shape memory alloy wires of the filtering body to regenerate the filter. CONSTITUTION: When circulating water flows in through a flowing route 5, detergent components in the circulating water are adsorbed by cotton threads, and dust and particles adhere to the surface of a filtering material 3 as filtration scum and the finer the particles are, the closer the particles go to the filtering core 2 in the inside of the filtering material 3. When water at high temperature is led to the filter through the flowing route 5 after the filter is used for a prescribed period, a temperature sensor 9 installed in the filtering material 3 detects the rise of the temperature and changes the route of the circulating water from a flowing out route 6 to a water discharging route 6 by a switching valve.  Further, when the temperature of the filtering material 3 rises and the temperature of the shape memory alloy exceeds the transition temperature, the shape memory alloy contracts and shrinks the cotton threads. As the result, the fine particles enter the inside of the filtering material 3 and the detergent components adsorbed by the cotton threads are pushed out to the outside of the filtering material 3 and discharged through the discharging route 7, and thus the filter is regenerated.

Abstract: PURPOSE:To prevent the creeping discharge by lengthening the creeping distance and to upgrade the voltage stopping power in a semiconductor device, thyristor, by a method wherein both of the substrate and the metal reinforcing plate are coated with a silicon rubber over the exposing part of the P-N junction between the substrate and the metal reinforcing plate and parts or the whole of the sides of the metal reinforcing plate. CONSTITUTION:A semiconductor substrate 15 is formed by the same method as the conventional one and a metal reinforcing plate 10 is bonded thereto. After the peripheral part thereof was cut, the substrate 15 and the metal reinforcing plate 10 are inserted in a plastic mold 21 for molding, and a gel-shaped silicone rubber A mixed with a hardner is poured therein. After the rubber A was made to cure, the mold 21 is released and a semiconductor device is constituted. According to this structure, the creeping distance on the surface of the silicone rubber A becomes a distance of E-F-G-H. Concretely speaking, the creeping distance, which has been 8mm. in examples obtained hitherto, becomes a distance of 12mm.. As a result, the creeping discharge resistance of the thyristor is upgraded.

Filed: 1989-08-10
Abstract: PURPOSE:To easily and clearly confirm the remainder of a recording form by storing the recording form on a recording form reception base and observing the recording form and the colored display part of a display plate through an inspection hole. CONSTITUTION:When the winding diameter of the recording form 2 decreases as the recording form 2 is used, the colored display part of the display sheet 10 is seen through the inspection hole 9. A user decides that the remainder of the form 2 is small, checks the stock of a form 2, and takes the steps for ordering when the form is out of stock. Then when the form 2 is further used and the colored display part of the sheet 10 is seen through the window 9, it is judged that the remainder of the form 2 is nearly zero and the form 2 is replaced with a new form 2. At this time, the form 2 is drawn toward a holding wall 32 by the conveyance of a feed roller 6 and the bottom plate 31 of the recording form reception base 3 has a downward slope toward the sending-out side of the form 2, so the form 2 is held at a specific position while pressed against the holding wall 32. Therefore, the remainder of the form 2 is not misjudged.

IPC: H03M1/34
Filed: 1988-08-22
Abstract: PURPOSE:To compare voltages at high speed by detecting a current flowing between junctions when a voltage is applied to two superconductors of a Josephson element. CONSTITUTION:Voltages V1, V2 are applied respectively to two superconductors S1, S2 of a Josephson element 1. Whether or not a current flowing to the Josephson element 1 is a maximum value I0 of a DC Josephson current is discriminated by a threshold current discrimination circuit 2. Then a dead band of a Josephson voltage V0 is given to compare it with the voltages V1, V2 at a fast speed. A D/A converter and an A/D converter with a fast speed are obtained by utilizing the comparators. If reset by each comparison is needed, a current flows to a control line C by a reset circuit 3 to destroy the superconducting state and to shut off the applied voltages V1, V2 tentatively at the same time. A current is fed to the superconductors S1, S2 respectively to discriminate whether or not the voltage between Josephson junctions is over the threshold voltage V0 thereby comparing the current.
