Title: Replenisher for gold plating
Inventor: WAKAMATSU KENJI
IPC: C25D21/14
Filed: 1987-06-16
Abstract: PURPOSE:To produce a replenisher for a gold plating soln. in a high yield of starting material by mixing an aq. soln. of an alkali metal gold cyanide with the carbonate of the alkali metal, purifying and recrystallizing the alkali metal gold cyanide. CONSTITUTION:Since the Au content in an Au plating soln. lowers in accordance with the progress of plating, a replenisher for Au plating is added so as to keep the Au content in the Au plating soln. in a prescribed range. When the replenisher is produced, 5-40wt.% alkali metal carbonate such as K2CO3 or Na2CO3 is added to an aq. soln. of an alkali metal gold cyanide such as KAu(CN)2, KAu(CN)4, NaAu(CN)2 or NaAu(CN)4. K or Na is used as both the alkali metals. The mixed soln. is well mixed by stirring to deposit and crystallize the alkali metal gold cyanide and the resulting crystals are purified by a recrystallization method. Thus, crystals of the alkali metal gold cyanide as the replenisher for the Au plating soln. are produced in a superior yield of Au from the starting material.

Title: Detector for turning speed of slanting plate type compressor
Inventor: KOUNO HIROYA
IPC: G01P3/488
Filed: 1980-10-24
Abstract: PURPOSE:To monitor the operation state of a slanting plate type compressor by making a cylinder block, having a slanting plate chamber, of a nonmagnetic material, and by making a slanting plate of a magnetic material as a part to be detected. CONSTITUTION:As a driving shaft 3 coupled with a power source turns a slanting plate 5 stuck to it to reciprocate a piston 8 in a cylinder bore 4, thereby compressing a fluid to be compressed. Through the turning of the driving shaft 3, a detected part consisting of the circumferential part of the slanting plate 5 moves on a periodic motion track and when the detected part confronts to a magnet 20, magnetic flux changes in density to generate a currnt at a coil 21 surrounding the magnet 20. Then, when a pulse-existence detector supplied with the said output detects no set time pulse existing, an electromagnetic clutch coupling the driving shaft with the power source is placed in a released state. Thus, the driving source and its relative equipments are protected.

IPC: B22D11/16
Filed: 1989-06-13
Abstract: PURPOSE:To grasp remaining molten steel quantity by arranging an instrument which detects variation of electric resistance between an electrode exposed onto the molten steel side from bottom part or side face near the bottom part of a tundish and an electrode arranged at part conducting with a mold to detect the remaining molten steel level. CONSTITUTION:When the molten steel exists in the tundish(TD) and the electrode A comes into contact with the molten steel, electric circuit is constituted with the electrode A12, molten steel 6, submerged nozzle, mold 9 (electrode B), electric wiring 15, battery 16, ammeter or ohmmeter 17 and electric wiring 14. When the molten steel exists in the TD, the electric resistance is little and comparatively large current flows, and when the remaining molten steel quantity decreases and slag comes into contact with the electrode A, the electric resistance rises and the current lowers. By this method, as the remaining molten steel quantity in the TD can be surely grasped, this is effective to reduce length of joining piece in sequential continuous casting of different steel kinds and also, as flowing of the slag in the TD into the mold can be prevented, stabilization of the operation can be obtd.

If the recording medium is present, it is discriminated. If it is paper, transmitted data D is processed by an image processing circuit A 27 to be transmitted to a head driver 24. Ink liquid drips are selectively delivered from 8 nozzles of a recording head 4. If it is an OHP sheet, transmitted data D is processed by an image processing circuit B 27 to be transmitted to the head driver 24. Ink liquid drips are selectively delivered from 4 nozzles of the recording bead 4, whereby only a high-density ink is used for recording. After the completion of the recording, a cap 24 is pressed against the head 4 to prevent the ink from drying. In this manner, a high-image quality recording can be applied on any of two or more different types of recording mediums.
