Abstract: PURPOSE:To eliminate a forced cooling and to provide a rapid, positive and accurate response in a liquid pressure control recording method by a heating of the recording liquid in which a time length required for causing air bubbles generated by heating to be varied up to a specified volume is made to be a specified value. CONSTITUTION:When a pulse signal P which is turned ON or OFF at the time tO tf is fed to the electrical-thermal change-over means 2, air bubbles are generated at the thermal acting part 7 at the time delayed from the time tO by a value taud, the volume V is increased as the time is passed and then finally it is reached up to the maximum volume Vmax at the time tP. When the pulse signal P is turned OFF at the time tf, the volume V starts to decrease. The time required for an extinction curve for the volume V to be changed from Vmax to Vmax/2 is tau1/2 and the time required for air bubble generating time to Vmax is tau0, then in case of a relation of 0<tau0<=10mus, resulting in making a relation of tau0<=tau1/2<=10tau0 and further in case of a relation of 10mus<tau0, resulting in making a relation of 10mus<=tau1/2<=10tau0.

Abstract: PURPOSE:To prevent a decrease in detection sensitivity due to variance in electrode capacity inherent to each touch electrode, by making the frequencies of retrieval signals supplied from an oscillator to the retrieval touch electrodes different in correspondence to the inherent electrode capacity of each touch electrode. CONSTITUTION:The inherent electrode capacities CY1-CY3, and CX1-CX3 of the touch electrodes Y1-Y3, and X1-X3 and contents corresponding to the resonance frequency of a resonance circuit consisting of respective resonance circuit 2 are stored in a storage element 3a. Touch electrode selecting signals for selecting the electrodes Y1-Y3, and X1-X3 successively are inputted to the storage element 3a of the oscillator 3, whose output is inputted to a D/A converter 3b. The output of the converter 3b is supplied to a voltage frequency converting circuit 3c. Consequently, when some touch electrode is selected, the selected touch electrode is supplied with a retrieval signal of frequency coincident with the resonance frequency of a resonating circuit 2 including the electrode capacity of the touch electrode from the oscillator 3. Thus, a decrease in detection sensitivity due to variance in electrode capacity inherent to each touch electrode is removed.

Abstract: PURPOSE: To achieve repairment of high reliability in a short time, by attaching a wire net to a damaged part at a position higher than the level of raw material charged into a shaft furnace, and by spraying irregular refractory to the damaged part to which the wire net is attached.  
     CONSTITUTION: In front of a part 7 of shaft furnace wall damaged by the impact of the charge of raw material,, the part which is at a position higher than the level x of raw material charged into the shaft furnace, is hung a heat resistant wire net 6. A hole 12 is made previously in a furnace wall 4 corresponding to the damaged part 7. An engaging means 13 attached with a messenger wire is inserted through the hole 12 into the furnace. When the top end of the engaging means 13 is caught by the wire net 6, the engaging means 13 is drawn toward the furnace wall, so that the net 6 is brought into contact with the furnace wall 4. Then the engaging means 13 is secured to the shell 1 so as to fix the wire net 6 to the inner wall 4 of the furnace. A long nozzle 16 is inserted through a manhole 8 into the furnace, through which a kneaded mixture of irregular refractory with water is sprayed to the damaged part. Presence of the wire net 6 allows the refractory material to contact closely with the damaged part and to form excellent repaird part which scarcely exfoliates and falls.

Abstract: PURPOSE:To obtain ceramics paper which is strong to impact, tensile force and bending force and is imparted with compressive strength by adhering and integrating silicon carbide fibers between the sheets of the ceramics paper, then calcining the same. CONSTITUTION:The silicon carbide fibers are held in place between two sheets of the ceramics paper such as ceramics paper or paper ceramics and these sheets are stuck to one sheet by a special adhesive agent such as, for example, heat resistant inorg. adhesive agent of a one-component thermosetting type. After the adhesive agent dries, the sheet is calcined for about 3-4 hours at 900-950 deg.C in a calcination furnace and is then cooled, by which the desired ceramics paper is obtd. The entire part is integrally converted to the ceramics and a sheet of the paper-like ceramics is formed according to this process for producing the ceramics paper. Since the silicon carbide fibers in particular is used, the paper is strong to the impact, tensile force and bending force and has the compressive strength. The purposes and range of use of this ceramics paper are, therefore, extremely wider than those of the conventional mere ceramics paper.
