Inventor: MEGURO TAKU
IPC: B22F3/00
Filed: 1985-09-04
Abstract: PURPOSE:To stably exhibit high magnetic permeability over a high frequency band by manufacturing coarse powder by feeding a melted Fe-Ni alloy having a specific crystal particle diameter or less directly into liquid, and using granules of fine powder having a specific mean maximum arc length ratio or larger obtained by pulverizing and relatively smooth surfaces. CONSTITUTION:Melted Fe-Ni alloy is directly feed into liquid to form 80mum or less of crystal grain diameter to manufacture shot or flat rough powder, fine powder of particle shape having 0.55 or larger of mean maximum arc length ratio obtained by further pulverizing the rough powder and relatively smooth surface is used as raw powder. When the maximum arc length ratio is 0.55 or larger, and the frequency characteristic of magnetic permeability is increased, but when the ratio is 0.8 or larger, the magnetic permeability decreases to 100 or less. Thus, the maximum arc length ratio is preferably 0.55 to 0.8.

Patent JP-S5897723-A (JP)
Title: Interface circuit
Inventor: ISHII TAKAYOSHI
IPC: H02J1/00
Filed: 1981-12-07
Abstract: PURPOSE:To obtain an initializing signal in an assured way for a device applied to a microcomputer, by inserting a diode in series to a pull-up resistance of an input/output circuit and as a result preventing detouring of a power supply among the devices. CONSTITUTION:The power supply voltage Vcc of the 1st device 100 flows into an input circuit and an output circuit 12 of the 2nd device 200 via the pull-up resistances 6 and 7, diodes 8 and 9 and connecting lines 101 and 102. The voltage Vcc entered the circuit 13 is applied to a diode 18 via a pull-up resistance 16. The diode 18 shows high resistance value since the voltage is applied backward to the diode 18, and the voltage Vcc does not enter a power supply circuit 11 of a device 200. When the power supply of the device 200 is applied, a capacitor C143 within an initializing signal producing circuit 40 is charged until it reaches the prescribed quantity of electricity. Thus the C143 is never charged before the application of a power supply. As a result, a malfunction is prevented.

Abstract: PROBLEM TO BE SOLVED: To cut a dial up line when it is not needed and to securely connect it if needed by permitting a first communication station to allocate a network layer protocol identifier to a second communication station, to hold it and to connect and cut the line in accordance with the presence or absence of communication data. SOLUTION: The first communication station (broadcasting station) 12 executes information delivery service through a satellite 13. More than one second communication stations (home) executes data communication to the first communication station through the dial up line The first communication station allocates the specified network layer protocol identifier (IP address) to the second communication station connected to the dial up line and transmits a line connection control signal inhibiting the use of the allocated IP address. During information delivery service, the connection controller 2 of the first communication station and the set top box STB 15 of the second communication station continues holding the IP address. Thus, dial line connection is cut, a line use rate is saved and it can securely be connected again when data does not exist for prescribed time during service.
