Filed: 1984-03-14
Abstract: PURPOSE:To determine the relative movement by a method wherein phase signals different by 90 deg. are outputted with the relative movement of two detecting bodies and values thereof at any time held simultaneously to determine the displacement value between pulse signals in comparison with a digital signal corresponding to both the signals. CONSTITUTION:Values of a sine wave and a cosine wave at the current time are held with sampling and hold circuits 4A and 4B by a touch signal. As the analog value is varied from a D/A converter 10 at the other inputs of voltage comparators 9A and 9B, the outputs of the voltage comparators 9A and 9B are inverted when both outputs give the same value. Asin(2pix/p) and Acos(2pix/p) can be learned by latching a digital value at this time with a latch circuit 6. Thereafter, (x) is found and added to by a numeral equivalent to the value of an up/down counter 3 multiplied by (p). The displacement value can be determined with a resolution set by a D/A converter 10.

In such a case, to an applying liquid supply pipe 6, the applying liquid is fed continuously. Also, after an engaging part of the supporting body 1 has passed through, the application is executed by using the second nozzle in which contamination of the tip of the nozzle is eliminated in advance, by a rotation of said nozzle 3. In such a way, since the applying liquid is not stagnant in the applying liquid supply pipe 6, a magnetic grain is not coagulated, and at the time of restarting the application, prescribed film thickness is obtained in a short time. Moreover, an applied surface being free from a longitudinal line is obtained.

Abstract: PURPOSE: To increase the amount of addition of a hardener, and to improve the sprayability of the mixture and reduce the cost and manpower for molding by kneading refractory particles and the liquid hardener then drying the mixture.  
     CONSTITUTION: Refractory particles, a liquid hardener and a hardening accelerator are kneaded, after which the mixture is dried. This dried mixture and a binder or a slurry prepd. by mixing a mold coating base material in this are spray-coated simultaneously or alternately to the surface of the mold to prescribed thickness. By this method, the amount of spray coating of the hardener can be increased. The  moisture stuck on the refractory particles, the moisture in the hardener, and volatile  materials are evaporated by the drying after the kneading of the refractory particles  and the hardener, by which the facing sand layer of a high rate of hardening is obtained. Hence, the packing work of backing sand is made possible from right after  molding of the facing sand, and the number of steps and manpower for molding are reduced.

Title: Jib derricking limiter in jib crane
Inventor: YOTAWARA HIDEKI
IPC: B66C23/92
Filed: 1990-02-28
Abstract: PURPOSE:To prevent a jib from exceeding an allowable elevation limit angle to a boom by installing a tension detector, capable of detecting the extent of tension being added to a jib supporter at time of jib application, in a proper spot of this jib supporter, while providing an electric control circuit generating a winch hoisting regulation signal. CONSTITUTION:When a jib 3 is reached to a spot just before an allowable derricking limit angle, tension of a jib supporter 4 is reached to the tension setting value being set by a tension detector 9, and at that time, a detection signal out of the detector 9 is emitted, operating a switch 20 (electric control circuit) to ON, whereby a solenoid valve 51 is operated On as well, while an unload valve 52 is also operated to ON. Then, the pressure in a winch hoisting side hydraulic pipeline 56 goes down, therefore a hydraulic 55 comes to a stop at once, and jib rising motion is stopped as well. Consequently, even if a main control valve 53 for hydraulic motor operation use is in a state of being operated to the winch hoisting side, the extent of combined turning moment between the jib 3 and the supporter 4 will in no case be decreased more than the allowable range, thus the jib is not toppled.
