Title: Method for reducing dust from ironwork
Inventor: SOMA HIDEAKI
IPC: C22B7/02
Filed: 1990-03-22
Abstract: PURPOSE:To reduce shrinkage in a specimen layer, to secure gas passage, and to improve reduction efficiency by inserting a heat resisting wire rod from the surface of a specimen layer of dust from ironworks into the inner part of this layer in a vertical direction and introducing a reducing gas from the lower part. CONSTITUTION:In fixed bed gaseous reduction for dust from ironwoks, such as converter dust, a heat resisting wire rod made of stainless steel, etc., is inserted from the surface of a specimen layer into the inner part of this layer in a vertical direction. Heating and reduction are carried out by introducing a reducing gas from the lower part. The effective insertion depth of the wire rod is >=50%, desirably 70%, of the layer height. Since the wire rod acts as resistance to the shrinkage in the specimen layer, the shrinkage in the specimen layer can be reduced, and further, the widening of the gap between the specimen layer and the furnace wall is inhibited and gas drift in the peripheral part of the specimen is decreased. Although a small gap is formed by the wire rod between this wire rod and the adjacent specimen, this functions as a gas passage and uniform gas flow in the layer can be secured. As a result, the specimen layer can be reduced rapidly and uniformly.

Title: Surface flaw detector
Inventor: SUGINO KAZUMI
IPC: G01N21/93
Filed: 1986-03-28
Abstract: PURPOSE:To improve the reliability of the inspection discrimination and defect detection by calibrating the inspection discrimination of signal processing in accordance with the result of the comparison of the detection signal of an IR detector and predetermined reference level. CONSTITUTION:The detection signal lr of the IR detector 1 is inputted via an amplifier 4 to a signal processor 5 by which the inspection discrimination such as defect detection is executed. The signal lr is inputted to a divider 7 of an inspection discrimination level setter 6 as well and is divided by the preset reference level lo. The output thereof lr/lo is inputted to a calibrator 8. The initial inspection discrimination level ho is calibrated by the output signal of the divider 7 in the calibrator 8 and the inspection discrimination level hr after the calibration is delivered to the processor 5. More specifically, the inspection discrimination level hr of the processor 5 is calibrated in accordance with the result of the comparison between the detection signal lr and the reference level lo and therefore, the inspection discrimination is not affected by the sensitivity of the IR detector even when there is a fluctuation in the sensitivity of the IR detector. The reliability of the inspection discrimination and defect detection is thus improved.

Title: Stacker crane
Inventor: MITANI KEIO
IPC: B65G1/04
Filed: 1992-02-20
Abstract: PURPOSE:To prevent the collapse of cargoes at the time of loading and unloading without any need of enlarging a facility by providing a means to incline a ramp. CONSTITUTION:At the time of loading a cargo on a shelf with a slide fork 4, the magnitude of the downward deflection of the slide fork 4 due to cargo weight is detected, and a drive motor 34 is actuated with a control section 40. As a result, a threaded member rotates and, in collaboration with a female thread 36, causes a turning frame 32 to turn. Thus, a ramp 33 is inclined in downgrade from the side of the shelf, thereby lifting the forward end of the slide fork 4. Consequently, the forward end of the slide fork 4, even when deflected down due to the weight of a heavy cargo under loading or unloading, can be corrected to be horizontal, thereby ensuring the prevention of the collapse of cargoes.

Abstract: PURPOSE:To make a bearing optimum as one for a high speed rotating body by spirally inserting a metallic sheet having metallic wires fixed on its one surface between a housing and a rotating shaft, and fixing the outside end of the metallic sheet to the housing. CONSTITUTION:A metallic sheet 3 having plural metallic wires 2 fixed on its face is spirally inserted into an annular gap 5 between the inner periphery of the housing 1 and a rotating shaft 4 inserted into the housing 1 to fix the outside end of the sheet 3 to the housing 1. Thus the most inside face of the sheet 3 comes into contact with the outer peripheral face of the shaft 4 to function as a bearing face, and a fluid film is formed between the bearing face and the surface of the shaft 4 during its rotation to perform bearing action. The sheet 3 therefore functions as the optimum bearing for a high speed rotating body.

Abstract: PURPOSE:To secure the seal, by forming a groove in an outer circumferential surface of a pressure plug in which an O-ring can be fitted, and connecting the groove with a bore in communication with a hole drilled in a shaft core thereby a compressing fluid can press the O-ring. CONSTITUTION:The groove 1b in which an O-ring is fitted along a seat ring 8 is formed in the outer circumferential surface of a pressure plug 1, the communication bore 1b in communication with the hole drilled in a shaft core is connected with a groove 1b, and the O-ring 1c is inserted in the groove 1b. Thus the compressing fluid from the communication bore 1a forces the O-ring 1c to the seat ring 8 so that the O-ring can firmly be fitted in a gap between the seat ring 8 and the pressure plug 1 to secure the seal. Since the pressure to be applied can be freely selected, if leakage from the plug part is discovered, the leakage can be prevented by controlling the pressure to be applied.
