CONSTITUTION: When a probe for liquid level detection 21 is downwardly moved via a penetration hole 12b by operation of a probe drive means 22 and the lower end part 21a of the probe 21 is brought into contact with a molten material X, it is in an electrically conductive state between the probe 21 and the molten material X, and a conduction-detection means detects whether the probe 21 is brought into contact with a liquid level L of the molten material X. At this time a position detection means 24 measures an ascending/lowering amount of the probe 21, and the liquid level L of the molten material X is measured by detecting upward and downward positions of te probe 21 at the time of conduction. The detection of the liquid level L of the molten material X is intermittently performed by lowering the probe 21 at proper intervals.  After liquid level measuring the probe 21 is upwardly moved by a prove drive means 22 and placed to stand-by in a separated state from the molten material X. The probe 21 is covered with a bellows 27, the inside and the outside of a fusion tank 11 are separated from each other, and upward and downward moving property is given to probe 21.

Title: Manufacture of bleeder and die for roll-forming used therefor
Inventor: YOSHIDA SHICHIE
IPC: B21H3/06
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To manufacture a bleeder by a roll-forming which easily works even a hard material. SOLUTION: A header blank is beforehand manufactured by cutting a round rod into a prescribed size and forming a hexagonal nut part and each part to a prescribed diameter with the roll-forming, and a first die and a second die for the bleeder supplied to the roll- forming by relatively shifting, are manufactured by dividing into three pieces of a chamfering die 10, screw roll-forming die 20 and grooving and chamfering die 30, respectively. These divided die parts are constituted by polymerizing in a prescribed order, and since the hardness of the die 10 in the surface is formed different from the other die, the sheet surface 2 of the bleeder is roll-formed with the chamfering die 10 and the screw part 4 with the screw roll-forming die 20 and an end surface 7 and a groove 6 with the chamfering die 30 can simultaneously be roll-formed from the header blank.  Further, the working and cutting of the sheet surface of the bleeder accompanied by the drawing and the cutting can be executed with the high hardness die. Further, each part of the bleeder can simultaneously be worked without cutting the end surface, groove and sheet surface. Since this bleeder is manufactured by the roll-forming and thus, the conventional cutting process can be omitted, the unevenness in the product is not caused and the cutting waste is restrained.

Title: Substrate-heating device
Inventor: MATSUSHITA MASANAO
IPC: C03B32/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To make uniform temperature distribution on the upper surface of a heat plate and to improve response when temperature rises or falls by arranging a capillary body along the ceiling surface and the inner surface of a sealed chamber being formed inside the heat plate. SOLUTION: The substrate heating body can raise the temperature of a heat plate 11 with improved response since a substrate W can be heated by utilizing condensation heat due to condensation liquefaction accompanied by the cooling of the steam of working liquid L for instantly moving the gaseous phase part of a closed chamber S. Also, in the substrate heating device, a wick material 12 as a capillary body is arranged along a ceiling surface ST and an inner surface SS of the sealed chamber S being formed inside the heat plate 11.  The steam of the working liquid L is liquefied by the ceiling surfaced ST and the inner surface SS of the sealed chamber S, then is transferred along the wick material 12 securely due to the capillary phenomenon without continuing to stay at that position and flows down and is accommodated in the sealed chamber S, thus making uniform the temperature distribution on the upper surface of the heat plate 11 along with the rapid spread of steam to an entire portion within the sealed chamber S.

As a result, the manganese ion in a manganese sulfate soln. is deposited on the cathode 2, and hydrogen is generated during the deposition. The vibration of the vibrator 6 is simultaneously transmitted to the cathode 2 through the rod 4, hence the cathode 2 is constantly vibrated in the electrolyte, and the hydrogen generated on the surface of the cathode 2 is surely separated from the cathode surface by the vibration. Accordingly, high-density manganese is deposited on the cathode 2 without occluding bubbles, and high-purity manganese is obtained.

Title: Method for judging leakage of container
Inventor: HIKASA TAKESHI
IPC: G01M3/32
Filed: 1989-04-11
Abstract: PURPOSE:To shorten a judging time by comparing the estimated value which is computed by an approximation for estimating pressure-decreasing amounts that are prepared in a plurality of kinds with an actually measured value, determining the estimated value, and performing measurement based on probability density after the inversion after the specified time has elapsed. CONSTITUTION:A steel drum 1 which is an inspection medium is tightly closed with a cap 1a. Thereafter, an electromagnetic valve 4 is opened, and high-pressure air is introduced from an air compressor 2 so as to provide a specified pressure. Then, pressure reduction after the stop of the inflow of the compressed air is sampled and detected with a pressure sensor 3 at every specified time. The detected pressure value is converted into a digital value through an A/D converter 6. Simulation is performed with a microprocessor 7 by the following way. The difference is computed based on the actually measured pressure value and the estimated value for every corresponding time interval which is output of a Kalman filter. The probability agreement between the actually measured value and the estimated value is computed for every time interval by multiple tests of hypothesis based on the difference. Thus the probability density is computed as the estimated value. In this way, the leaking state of the drum 1 is judged.
