Patent JP-H0576697-A (JP)
Title: Centrifugal extractor
Inventor: ARAKI KOJI
IPC: D06F49/00
Filed: 1991-09-17
Abstract: PURPOSE:To prevent trouble of an extracting machine by shutting off current supply during a first predetermined period from the running start to stationary rotation of a motor and the second subsequent predetermined period to judge that the vibration of an extracting tank is abnormal when a difference between the rotational frequencies of the motor during both predetermined periods is small than a set value. CONSTITUTION:A timer of a control section 12 counts since the start of extraction running, and current supply to a motor 19 is shut off after 3 seconds to measure the first rotational frequency of inertia. This measurement is completed within 5 seconds of predetermined time after the motor 19 is turned off. Next, the motor 19 is turned on and then turned off after 3 seconds to measure the second rotational frequency of inertia. This measurement is completed within 5 seconds of predetermined time after the motor 19 is turned off. A difference between both rotational frequencies of inertia, i.e., the rise of rotational frequency is obtained and if it is smaller than a set value, an extracting machine is detected to be abnormal. If the intermittent running is repeated and the abnormalities are detected three times, the motor 19 is turned off and the abnormality is indicated on a LED indicating section 13. Thus, vertical vibrations difficult to detect for a safely switch 14 can be detected to prevent trouble of the extracting machine.

Title: Production of magneto-resistive element
Inventor: KAWAWAKE YASUHIRO
IPC: G11B5/39
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To easily align the magnetization of a fixed layer by forming a magnetic layer (fixed layer) which is not easily magnetized and rotated by an external magnetic field and a magneto-resistive(MR) element composed of a magnetization rotation suppression layer, holding both at a specific temperature range and impressing the magnetic field of a specific range thereto. SOLUTION: The directions of easy magnetization of the fixed layer 3 and a free layer 5 are intersected orthogonally with each other and are so arranged that the direction of the signal magnetic field to be detected is made parallel or counter parallel to the magnetization direction of the fixed layer. The control of the easy axes is first executed by the magnetic field impression to a substrate during desosition. The magnitude of the magnetic field is specified to at least >=10 Oe and to <=200 Oe as an upper limit. Also, the heat treatment temperature is specified to >=200 to <=300 deg.C. The magnetic field impression direction of this time is made parallel to the direction of the magnetization of the fixed layer 3 like an arrow H.  The control of the magnetization direction of the fixed layer by the heat treatment using such weak magnetic field is particularly effective when the magnetization rotation suppression layer of a relatively low bias effect is used.
