Title: Manufacturing method of rare earth-iron-nitrogen magnetic material
Inventor: TAKAHASHI TAKESHI
IPC: H01F1/06
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To relax the shock acting on magnetic powder at the time of collision of the powder and restrain the stress acting on a crystal structure at the time of pulverization, by adding and mixing a lubricant to a magnetic material and then pulverizing the mixture. SOLUTION: Magnetic powder of a magnetic material expressed by a formula RaFe(100-a-b-c)MbNc is prepared (with R contains at least one type of rare earth element including Y and Sm as an essential element at approximately 50at% or more, and M is at least one of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W, while a, b and c represent atomic percentages having the relations of 5<=a<=20, 0<=b<=5 and 3<=c<=30, with the remaining portion being Fe). Then, fatty acid as a lubricant is added to and mixed with the magnetic powder. The mixture is then pulverized by using a jet mill, more preferably, an airstream jet mill. Thus, the fatty acid film is caused to exist between colliding substances at the time of collision, thereby providing good lubricity.  Thus, the shock acting on the magnetic powder at the time of collision is relaxed, thereby reducing the quantity of defects introduced by pulverization and exhibiting excellent magnetic property.

Title: Engagement device
Inventor: MORITA TAMAO
IPC: H01F7/02
Filed: 1985-11-15
Abstract: PURPOSE:To prevent influence of magnetism on a magnetic recording card, etc. by fixing a fitting member consisting of non-magnetic metal where a couple of legs for bending are protruded in the same direction to the plate formed like a seat plate with the surface of the seat plate closely attached to the rear surface of attracting surface of ferro-magnetic material. CONSTITUTION:The plate part 3b of ferro-magnetic material 3 is attracted by the magnetic pole surface b of female device a through a case 4, and the protruded rod 3a and the protruded rod 2a of ferro-magnetic material 2 are collided and attracted to each other at the end portions thereof within a hole 1a of permanent magnet 1. The line of magnetic force of magnetic pole surfaces a, b is concentrated to the plate parts 2b, 3b of ferro-magnetic materials 2, 3, and this magnetic flux is guided to the protruded rod parts 2a, 3a to form a magnetic circuit, thereby obtaining an effective attracting force. Since the fitting material is formed by non-magnetic metal as explained previously, when it is attached to a bag, etc., the magnetic force of permanent magnet does not leak into the interior of bag with the leg portion of such fitting materials used as the magnetic path.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a porous membrane and to maintain high membrane filtration flow rate over a long period of time by forcibly feeding ozone-containing water to the opposite direction to a filtering direction and also rocking the porous membrane by introducing bubbles to the raw water side of the porous membrane in the case when the porous membrane used for filtering various kinds of raw water is washed. SOLUTION: The raw water 1 consisting of river surface running water, etc., is fed forcibly to a membrane module 4 by a raw water feed pump 3 from a circulation tank 2, and the filtered water obtained here is stored at a filtered water tank 5. At the time of back washing of the membrane module 4, the filtered water in the filtered water tank 5 is fed forcibly to an ejector 8 by a backwashing pump 8 and allowed to contact with the ozone generated at an ozonizer 9, then sent to the membrane module 4. On the other hand, the air generated at a compressor 7 is sent to the raw water side of the membrane module 4 to air-bubble the membrane module 4. In such a way, an adhered matter at the membrane module 4 is easily decomposed oxidatively and also surely peeled by air-bubbling.

Title: Multiple mucpu roll-out method
Inventor: KAWAMURA HIROTA
IPC: G06F11/34
Filed: 1988-10-14
Abstract: PURPOSE:To obtain enough information for fault analysis by transferring the memory contents of a subordinate muCPU to a main muCPU through a bidirectional interface at the time of roll-out execution and storing the contents on a storage medium after the transfer is completed. CONSTITUTION:The main muCPUP side decides whether the contents of a command indicate an IPL process or roll-out process and when the IPL process is indicated, an IPL process is performed as usual after an IPL command is sent to the subordinate muCPU. When the roll-out process is indicated, memory contents such as work information required for fault analysis read out of the main muCPU and a transfer indication command for the memory contents is sent to the subordinate muCPU. Then the memory contents of the subordinate muCPU side are transferred to the memory in the main muCPU and stored on the storage medium as well as the memory on the main muCPU side. Thus, much subordinate muCPU information is stored on the FD at the time of the fault occurrence to shorten the analytic time at the time of fault occurrence.

Title: Frequency variable oscillator
Inventor: MINATO TAKESHI
IPC: H03C3/00
Filed: 1984-12-06
Abstract: PURPOSE:To increase the response speed of a frequency variable oscillator by pulling in the title oscillator with periodic synchronous control up to a level near a focusing frequency in a mode where no FM modulation is applied, then switching the operation to a phase synchronous control, and switching this mode to the periodic synchronous control again in case a mode where the FM modulation is applied. CONSTITUTION:When a switch 17 used between an FM mode and another mode is set at an another mode, an error signal of the pulse width proportional to a frequency error is outputted from a phase comparator 6. The comparator 6 functions as a period comparator when said pulse width is larger than the prescribed value, and then functions as a phase comparator when the pulse width is reduced less than the prescribed value. Therefore, the frequency focusing speed is increased with the equivalent stability compared with a case where the focusing operation is carried out with a phase synchronizing loop only. Then the comparator 6 functions as a period comparator to control the frequency when the switch 17 is set in an FM mode.
