Title: Sorting-selecting test for magnetic bubble memory chip
Inventor: HIROSHIMA MINORU
IPC: G11C11/14
Filed: 1979-09-26
Abstract: PURPOSE: To make it possible to decide securely the existence of a new-creative defective loop, by increasing the intensity of a revolving magnetic field much greater than that of the least upper bound magnetic field in memory-operation securing range for an extremely short period.  
     CONSTITUTION: A magnetic bubble memory chip is equipped with minor loop (m), read major line RML, write major line WML, magnetic bubble detector D, magnetic bubble generator G, replicate gate R, swap gate T, and guard rail GR. To decide the existence of a defective loop, bias magnetic field intensity HB is increased about 50% to clear bubbles and revolving magnetic field intensity HR is increased above the maximum value of value H 1  under normal use condition. At the same time, a frequency in revolution is lowered. Then, the revolving magnetic field intensity and revolution frequency are returned under the normal use conditions to read information in all addresses of all minor loops, so that a loop out of which a bubble is read out will be considered to be defective.

Filed: 1992-04-15
Abstract: PURPOSE:To prevent the contamination of an optical system so as to accurately measure the water content of powder by installing two lid plates to the taking- out port of a cyclone and providing an infrared-ray absorption type water content detector and air discharging device. CONSTITUTION:Powder is taken out through a double-damper device 10. The powder is accumulated on an inside lid plate 13 in a state where both the lid plate 13 and an outside plate 14 are closed. When the quantity of the powder increases and, after the plate 13 opens downward and the powder drops onto the plate 14, returns to the horizontal position. Then the lip 14 opens downward and the powder is transferred to a receiving container. Thus the discharge of a large quantity of powder at once is prevented by alternately opening the plates 13 and 14. The sensor 31 of a water content detector 30 is provided near the plate 14 and the sensor 31 detects the water content of the powder on the plate 14. In addition, cleaning air is blown upon the detecting section of the sensor 31 whenever the plate 14 opens and the powder is discharged. Therefore, the deterioration of measurement accuracy can be prevented, because the detecting section is cleaned and the contamination of an optical system is prevented.

Abstract: PURPOSE:To achieve the improvement in discrimination ability at the reading of information with a simple constitution by providing a 1/4 wavelength plate between a polarizer and a light splitting means and polarizing the reflected light from the magnetic film to linearly polarized light thereby increasing the contrast. CONSTITUTION:Light from a light source 1 is linearly polarized with a polarizer 2, after which it is elliptically polarized by a 1/4 wavelength plate 8.
