Title: Refractory duct
Inventor: WATANABE YOSHIO
IPC: F16L9/10
Filed: 1978-06-06
Abstract: PURPOSE: To improve life and reliablility of a refractory duct, to be used in a position where molten metal passes, by manufacturing it with dehydrated unbaked refractory.  
     CONSTITUTION: This unbaked refractory duct 7 is made of castable refractory or compacted material, and while a wooden mold is used for forming hollow section, it is to be removed after completion of a furnace. Thus manufactured unbaked duct 7, whatever the type of refractory may be used, is to be treated in a drying furnace of approximately 120°C for removal of free water content. Since it is possible, in this way, for the unbaked duct 7 to get only its heated section and the surrounding area baked gradually by being preheated before passing of molten metal and exposed to the heat of molten metal when it is passing, disproportionate thermal stress working upon all sections of the duct can be naturally absorbed. And as a result, life and reliability of the duct can be remarkably inproved.

Filed: 1980-05-22
Abstract: PURPOSE:To cope with running devices for all cars without requiring the increase or decrease of the hardware, by changing control constant and variables in a program instructing the processing steps to a microprocessor. CONSTITUTION:A speed-meter cable 19 is rotated in proportion to a car speed through the running of a car. Thus, a rotating magnet 20 rotates in proportion to the rotation of the cable 19, thereby causing the change in the magnetic field. This change is detected at a Hall IC21 to produce the pulse in proportion to the car speed, and this pulse is delivered to a pulse generating circuit 1 for car speed. Further, the car speed resolution is increased by multiplying the pulses from the Hall IC21 at the circuit 1. This multiplied pulses are counted 2 for a given time and are inputted to a CPU9. Thus, the CPU9 receives a car speed information and scans the set state of an acceleration switch 3 and a deceleration switch 4, a prescribed processing is made according to the program of an ROM10 to outut the acceleration and deceleration signals.

Abstract: PURPOSE:To prevent any crack or separation fro developing in a tablet-like mixture during the remolding work of the said mixture by increasing the ratio  of the outer diameter of the said mixture to the inner diameter of a positive  ring. CONSTITUTION:After a positive ring 2a is attached around a tablet-like mixture 2, which is prepared by roughly molding a positive mixture and is indicated in the figure, they are inserted into a battery case. Next, the mixture 2 is repressed and remolded with a metal mold so that the upper surface of the ring 2a and the upper surface of the mixture 2 become even. here, the ratio of the inner diameter R(x) of the ring 2a to the outer diameter P(x) of the mixture 2, which was 100 to 94.3 in a conventional example, is 100 to 99.1-97.2 in this invention. By thus molding the mixture 2, the pressure distributions of the upper surface and the bottom surface of the mixture 2, differently from a conventional example, don't become inhomogeneous during the above repressing work, and this fact work remarkably effectively for preventing any crack or separation from developing in the surface of the mixture 2.
