Title: Continuous casting method
Inventor: OOHIRA TOSHIAKI
IPC: B22D11/04
Filed: 1979-07-23
Abstract: PURPOSE: To make the yield of molding higher by obtaining the margin for expansion of mold walls from the rate of shrinkage and the amount of shrinkage of the ingot width when the pouring speed drops thereby expanding the widt between the mold walls so at to conform to the margin for expansion, in performing continuous casting with a variable width mold.  
     CONSTITUTION: If the apparent rate of width shrinkage of an ingot 1 when the pouring speed at the final period of casting using a variable width mold drops is expressed by αt=(Lt-L)/Lt, the amount of width shrinkage is ΔL=(Lt-L). Hence, the margin for expansion of the short side walls of the mold in the each ingot position when the pouring speed drops is dΔL/ t. The short side walls of the mold are widened with lapse of time to allow for shrinkage so as to conform to the margin for expansion dΔL/αt from the ingot position 0 when the pouring speed drops, whereby the width of the ingot 1 is expanded.

Abstract: PURPOSE:To make it possible to keep the lubricant of an electric fan oscillating device in a preferable condition, by providing each small projection at both ends of each inner surface of guide holes into which each guide pin is inserted, in an electric fan whose oscillation is obtained by driving a motor to make each guide pin guide a slide cam and vertically reciprocate the slide cam. CONSTITUTION:When an eccentric cam 11 which is fixed to the output shaft 4a of an oscillating electric fan motor 4 is rotated by the motor, a slide cam 12 is guided by each guide pin 14, 14 so as to be reciprocated in its vertical direction. Then the reciprocation of the slide cam 12 results in the vertical oscillation of the electric fan through a rod 13, a bracket metal 3, and a frame 2. In this case, each small projection 12c which is projected inward, is formed at both ends of each inner surface of guide holes 12a into which each guide pin 14 is inserted. Thus, while each guide pin 14 is relatively moved in the guide holes 12a, lubricant is gathered in a space 12b in the periphery of each small projection 12c. Consequently, the squeeze of the lubricant caused by each guide pin 14 can be prevented so that the occurrence of strange noise can be prevented.

Abstract: PURPOSE:To foresee simply rupture strength at high temp. by measuring previously a relation of stresses from normal to high temp. when an Si3N4 ceramic produces a sound by extremely small rupturing, and measuring a stress during the sound production of said ceramic at normal temp.. CONSTITUTION:A resistance wire 11 such as nichrome wire is embedded at a neutral surface (place equivalent to 1/2 of plate thickness) of the Si3N4 ceramic 10 to heat electrically the wire 11. The stresses during the sound production at each temp. T from normal temp. to 1000 deg.C are measured by placing the test piece 10 on supporters 3, 4 as shown in a separate figure to obtain previously a temp. and stress relation shown by an equation (deltaAE.RT is stress at normal temp., deltaAE.HT is that at high temp.). A graph made from the equation is also permissible. The stress of a Si3N4 test piece 1 to be inspected during the sound production at normal temp. is obtained by detecting by sensors 5, 6 the sound caused by the fine rupture generation by pushing a pressing part 2 in an arrow direction. The rupture strength at desired high temp. can be foreseen simply by using the relating equation or the graph from the stress thereat.

Moreover, the control circuit 12 sets an optimum signal read time interval from a memory 1 or 2 storing a signal to be synchronized based on the difference from the length of each signal so that the read time interval of each signal is equal to each other. Thus, the synchronization between the video signal and the audio signal is attained. Moreover, the video signal or the audio signal whose length is revised is subjected to frequency correction by a video frequency correction circuit 13 or an audio frequency correction circuit 14 to be restored to a natural video image and an audio signal without a sense of disorder.
