Title: Drum type centrifugal dehydrating device
Inventor: SUOU KIYOYUKI
IPC: D06F49/00
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To accurately detect the size and position of an eccentric load caused by unevenly distributed laundry with simple constitution. SOLUTION: A PWM control part 32 controls to increase the rotating speed of a drum 5 to specified rotating speed by PWM control and then fixes the pulse width of a PWM control signal so that fixed driving voltage corresponding to the rotating speed near the specific rotating speed is applied to a motor. At this time, if eccentric load exists in the drum 5, the speed of the drum 5 is fluctuated corresponding to the position of the eccentric load. An eccentric load detecting part 33 obtains a pulse signal changed according to the rotational fluctuation of the drum 5, from a rotating speed detector 43, and obtains the eccentric quantity from the fluctuating amplitude of the pulse width of the signal.  A rotation marker corresponding to the specific rotating position of the drum 5 is obtained by a rotation sensor 19, and the eccentric position quantity is obtained from a clearance (angle) between the rotation marker and the appearing position of the minimum pulse width of the signal. The eccentric load can therefore be detected in a control part 30.

Filed: 1978-06-19
Abstract: PURPOSE: To form on the surface of iron alloy material metallic carbide coating layer excellent in corrosion resistance, mechanical strength, and peel resistance, by heating the surface of the iron alloy material, previously plated with Cr, in the presence of 5a group elements or Cr.  
     CONSTITUTION: On the surface of a iron alloy material contg. C more than 0.2% is formed a plated layer of Cr 2W80 μ in thickness. The Cr-plated material is heat- treated at a temp. 800W1,100°C for 1W30hrs in the presence of 5a group elements or Cr by molten salt bath method, molten salt electrolysis, powder method, or gas phase method. The C contained in the iron alloy material is diffused to the Cr coating layer to form a Cr carbide layer. At the same time, 5a group elements or Cr supplied from outside reacts with the C contained in the Cr carbide. Hereby  layers of Cr carbide and 5a group element carbide are formed in a state diffused  each other to form a coated layer of excellent corrosion resistance, mechanical  strength, and of very strong peel resistance.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic disk medium which is extremely little in the output fluctuation in tracks. SOLUTION: This magnetic recording medium is a disk-shaped magnetic recording medium constituted by forming a magnetic layer via a ground surface layer at need on a disk-shaped nonmagnetic substrate and, in some cases, further forming a protective layer and a lubricative layer thereon.

Abstract: PURPOSE:To contrive reduction of solvent ingredients in exhausted air and to check rise of equipment costs, by providing a condensation channel composed of metallic material with high heat conductivity in a recovery channel between a gutter and an ink fountain and by installing the said condensation channel while being connected to a metallic casing of the equipment. CONSTITUTION:Ink stirred into air by a recovery pump 11 at a gutter 9 and a recovery channel 10 is guided into a condensation channel 12. The condensation channel 12 is composed of metallic material with high heat conductivity and is provided with an inlet 12a, a condensation wall 12b and an outlet 12c, which are directly connected to a metallic casing 14 so that the casing 14 can be used as a radiator. Mixture of air and ink taken in from the inlet 12a hits against the condensation wall 12b and solvent ingredients vaporized in the air condenses into liquid and is brought back into the ink. The ink is then guided through the outlet 12c and a recovery channel 13 and is brought back to a ink fountain 1. The recovery channel 13 is made larger than the recovery channel 10 in diameters, so that it serves to prevent the ink from becoming misty condition being mixed again with the air and to reduce occasions of re-vaporization of the solvent by slowing down the speed of the running liquid. The condensation channel 12 is connected to the casing part cooled by a blower 15 which cools by ventilation the inside of a casing body 14 of the equipment.
