IPC: H05K9/00
Filed: 1988-07-21
Abstract: PURPOSE:To improve the dispersibility of magnetic shield properties into a bonding agent by specifying not only the average thickness, the average aspect ratio, and the particle diameters of particles but also the kind of a bonding agent in the cases of flat, amorphous alloy soft magnetic particles which have a large shield effect on a magnetic field in the specific direction as well as magnetic shield materials consisting of the bonding agent. CONSTITUTION:Amorphous alloy soft magnetic particles having an average thickness 0.01-1mum is used as a magnetic powder and a bonding agent which cures radiation setting type compounds comprising an ethylenic double bond by radiation is used as a binder. Further, an aspect ratio of particles is more than 10 and respective diameters of the particles are distributed as follows: the particles having the diameters 10-50mum are in the amount of 35wt.% or more; those having diameters exceeding 88mum are 0.5wt.% or less; and those having diameters less than 3mum are 16wt.% or less. Moreover, an average ratio of long axes to short axes of the particles becomes 1.2 or more. This material is superior in magnetic shielding properties and the particles are hardened without taking a long time and the resultant magnetic shield material exhibits high resistance to weather and endurance.

Title: Production of ductile cast iron
Inventor: SHIMAMURA IKUTARO
IPC: B22D1/00
Filed: 1994-07-11
Abstract: PURPOSE:To provide a producing method of a ductile cast iron, by which an Mg treatment can simply be executed and the fume of MgO and Mg vapor is difficult to develop at the time of tapping off molten iron. CONSTITUTION:An Mg alloy is laid on the bottom of a ladle. Then, granular and powdery materials containing granular and powdery metal having magnetic property are spread on the Mg alloy to cover the Mg alloy. Thereafter, the molten iron is poured into the ladle and further, the molten iron is cast from the ladle by the well-known method to produce the ductile cast iron. By this method, since the granular and powdery metals are magnetized, these metals are easily and mutually attracted. Therefore, the magnetized granular and powdery metals spread on the Mg alloy surface are difficult to drop into gaps among the granular materials of the Mg alloy, and these metals are covered on the Mg alloy, like one sheet of cloth. Further, since the Mg alloy is surely coated with a little quantity of the magnetized granular and powdery metals, impurity in the magnetized metals is difficult to mix into the ductile cast iron and then, the deterioration of mechanical property of the ductile cast iron can be prevented.

IPC: H04B1/707
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To conduct synchronization processing in a short time by conducting synchronous capture of an asynchronous channel. SOLUTION: A signal from each satellite is supplied to receiving processing circuits 5-1-5-4 of channels 1-4, processing of inverse spread spectrum and PSK demodulation is conducted, navigation messages DT1-DT4 from first - second satellites is obtained, then sent to a CPU 11. In the CPU 11, position measurement is conducted by utilizing the time of each navigation message and orbit data. In the CPU 11, the synchronous state of each channel is judged in the level of inversely spread spectrum output (correlative output) of a signal from the satellite, and synchronous process is conducted in off synchronous state.  In the synchronous process, although time base data more than bit number is required after reaching synchronous (bit demodulation) state, when other channel (i) synchronous-processed exists in synchronous process of a channel (j), time access data more than bit number is used. Obtaining the time base data more than bit number by detecting preample is unnecessary, and synchronous process can be conducted in a short time.

Abstract: PURPOSE:To make it possible to prevent unbalance in load allotment by the combination of a low-cost inverter and a low-cost general purpose motor by detecting the torque of an AC motor and by drooping speed command values against an increase in detected torque value. CONSTITUTION:Power from a power supply 2 is converted by an inverter 3 having a required voltage and a required frequency, and an induction motor 4 is operated by this AC power.
