Title: Heat shielding cover
Inventor: TAKASHIMA TADASHI
IPC: B22D41/00
Filed: 1980-07-03
Abstract: PURPOSE: To prevent the heat radiation of a furnace, a fire box, etc. of which the inside is of high temps., by providing a closed empty room to the bottom surface of outer side, and lining the bottom end surface with a refractory heat insulating layer consisting of hollow bodies of alumina or zirconia, refractory fillers and binders.  
     CONSTITUTION: A refractory heat insulating layer 2 is provided to the places which are the bottom end surfaces of an empty chamber 1 having a reflective surface 3 on the bottom surface on outer side and the heat shielding cover on the bottom side of the chamber 1. Therefore, the radiation heat from, for example, molten steel surface is shut off by the layer 2, and the radiation heat past this is reflected and proofed by the surface 3. Since the air in the chamber 1 above this is of low heat conductivity, the dissipation of heat to the outside is prevented. The layer 2 is constituted of one or both of hollow bodies of alumina or zirconia, fillers of alumina, corundum, etc., and binders such as water glass, colloidal silica, and the like.

Abstract: PURPOSE:To eliminate the occurrence of wrinkle and unsatisfactory winding at the time of recording by a method wherein a thermal transfer recording medium is formed by providing a thermal transfer ink layer on a top surface of a heat-resistant substrate and a heat-resistant protective layer containing 25 - 90vol.% heat-resistant corpuscles on a rear surface thereof. CONSTITUTION:A hot melt substance, a thermoplastic resin, a coloring agent, fats and oils, and others are mixed and dispersed in a suitable organic solvent. The obtained dispersion liquid is applied on a heat-resistant substrate, such as polyester films and polycarbonate films, and dried to form a thermal transfer ink layer on a top surface of the substrate. On the other hand, a coating liquid is prepared by mixing and dispersing a heat-resistant resin and heat-resistant corpuscles as main components in a suitable organic solvent. This coating liquid is applied on a rear surface of the heat-resistant substrate and dried to laminate a heat-resistant protective layer, in which the heat-resistant corpuscles are incorporated in the ratio of 25 - 90vol.% to all the solid content of the heat- resistant protective layer. In this manner, a thermal transfer recording medium is produced.

Abstract: PURPOSE:To easily switch a system without depending on software processing by receiving system designation information representing the system in operating, inserting a control signal channel decided in advance to a specific bit, and transferring it to a subscriber circuit part. CONSTITUTION:A control part MDX in a master equipment A, when receiving SYS information (system designation information) from a system selection part SYSSEL, inserts it to the specific bit of the control signal channel S, and transmits it to a remote subscriber circuit part B. Also, when the control signal channel S is received, the subscriber circuit B branches the system switching bit b0 of the control signal channel S by the control part MDX, and sends it to the selection part SYSSEL in its own system. Thus, by branching transmission from the master device A to a remote place synchronizing with the system of an exchange EX and switching the system of the subscriber circuit part B, it is possible to verify the normalcy of the system on standby as a spare system, and to improve the reliability of the system.

Abstract: PURPOSE:To display a present time and an alarm time by switching in an analog display mechanism, by a method wherein a driving pulse equivalent to the time difference between the present time and the alarm time is given to an electromechanical converter. CONSTITUTION:The output of a time reference source 7 is subjected to frequency division 8 and given to an electromechanical converter 13 through a control switching circuit 9 and a driving circuit 10. A clock function controlling circuit 12 counts a clock signal and a switch input signal 11 for an alarm set, and when an alarm time comes, it makes a sound control circuit 14 operate to generate 15 an alarming sound. The clock function control circuit 12, memorizing the time difference between a present time and an alarm time, delivers a quick forwarding pulse equivalent to the time difference from the driving pulse 10 when the alarm time and the present time are switched for display in an analog display mechanism 1. A clock signal generated while the display in the analog display mechanism is switched over is counted as an interrupt signal, and thus the present time is kept correct constantly.
