Patent JP-H06126212-A (JP)
Title: Air cleaner
Inventor: TAKAHARA TOSHIHIRO
IPC: B03C3/14
Filed: 1992-10-15
Abstract: PURPOSE:To accurately detect the extent of contamination to operate equipment without being affected by the humidity of air. CONSTITUTION:Discharge electrodes 31A, 31B for generating corona discharge installed in an air sending passage 1a are installed and a filter 4 for collecting electrified, contaminated particles is installed downstream of the electrodes. Reference electrodes 32A, 32B for generating corona discharge are installed to pass the air from which dust has been previously removed through them. In a controller, differences in discharge current between the discharge electrodes 31A, 31B and reference electrodes 32A, 32B are detected to control the revolution of a blower 2 accordingly. When the humidity of air is changed, the discharge current of any of the discharge electrodes 31A, 31B and the reference electrodes 32A, 32B is increased and decreased to the same degree. Since the discharge current is changed by the concentration of the contaminated particles as well as the humidity in the discharge electrodes 31A, 31B, the differential discharge current is detected, causing a change in discharge current due to the influence of humidity to be cancelled, allowing the revolution control of the blower based on the concentration of contamination only to be accurately performed.

Abstract: PURPOSE: To prevent a resonance by a system impedance and a load-side capacitor and thereby prevent the appearance of a higher harmonic current component which is caused by a higher harmonic voltage component of the bus bar voltage by considering an active filter as an equivalent resistance at a specified frequency by a connection voltage detection method. CONSTITUTION: This is a combination of two methods; a load current IL detection method wherein a higher harmonic current component ILh of a load 3 current IL is detected and a first compensating current Ian which is opposite phase to the higher harmonic current component ILh is generated and an active filter (AF) 13 connection voltage detection method wherein a higher harmonic voltage component of a bus bar 2 voltage Vs is detected at a power reception point B and a second compensating current Iav which is in phase with the higher harmonic voltage component and which has an amplitude proportional to that of the higher harmonic voltage component. The higher harmonic current component ILh which appears on the load 3 side is cancelled and compensated for by the load current IL detection method.  And, by the AF 13 connection voltage detection method, the AF 13 is apparently considered as an equivalent resistance at a specified frequency and thereby a resonance is prevented from occurring.

IPC: G11B5/39
Filed: 1989-11-27
Abstract: PURPOSE:To obtain the magnetic head with the reproduction output not fluctuated by forming a step, etc., on the element film to inhibit the fluctuation in magnetic domain structure of a magneto-resistance effect element and locally changing the surface shape of the element. CONSTITUTION:A groove 2 parallel to the longitudinal direction is provided at the center of an MR element 1, and a groove 3 extending from its end to the four corners of the element 1 is furnished. An electrode 4 shown by the broken line is provided on both sides of the element so as to cover a triangular part consisting of the end part of the element and groove 3. At this time, a 180 deg. domain wall 5 and a 90 deg. domain wall 6 are generated along the grooves 2 and 3 in the magnetic domain structure. When a signal magnetic field enters vertically in the longitudinal direction of the element 1, the 180 deg. domain wall 5 in the magnetism sensitive part is not moved. Meanwhile, the 90 deg. domain wall 6 tends to generate along the groove and step due to the magnetic charge and stress concentration produced on the grooves 2 and 3 and the end of the step, its irregular movement is hardly caused. As a result, the generation of noise due to the movement of the domain wall is prevented.
