Title: Ferromagnetic metallic particulates for magnetic recording medium
Inventor: ATA MASAFUMI
IPC: H01F1/06
Filed: 1991-05-31
Abstract: PURPOSE:To prevent the surface of ferromagnetic metallic particulates from being oxidized while the ferromagnetic metallic particulates are preserved by treating the surface of the ferromagnetic metallic particulates with a dithionite solution. CONSTITUTION:2.0g of ferromagnetic metallic particulates is added to 50ml of dithionite solution. It is left as it is for about two hours. In order to prevent oxidation of ferromagnetic metallic powder due to contact with air, the work should be done in an airtight state. The treated solution is filtrated using a film filter and then the obtained ferromagnetic metallic particulates are vacuum-dried at 30 deg.C for eight hours to obtain treated powder. It is known that the ferromagnetic metallic particulates surface-treated with dithionite of every kind has saturation magnetization 73 and a coercive force Hc, both of which deteriorate very small, and has a stabilized magnetic characteristic with the passage of time. Since the ferromagnetic metallic particulates are surface-treated with dithionite such as Na2S2O4 or ZnS2O4) and thereby a dithionite film is formed on the surface of the ferromagnetic metallic particulates, the ferromagnetic metallic particulates are provided with a resistance to oxidation and therefore a change of saturation magnetization with the passage of time is held low.

Filed: 1995-06-22
Abstract: PURPOSE: To obtain an equipment for locally evaluating an insulation film by providing a voltage source for applying a voltage between a substrate and a probe, and means for measuring the capacitance between the substrate and probe. CONSTITUTION: The surface of an insulator film 10 formed on a semiconductor substrate 11 is touched, with a predetermined contact pressure, by a probe 9 provided at the forward end of a cantilever 8. Voltages generated from AC an DC voltage generators 18, 19 are applied between the cantilever 8 and a conductive layer formed on the probe 9 through the substrate 11 and the ground. Output signal from a capacity sensor 16 (capacitance detection means) is fed to a controller 20. The substrate 11 is moved two-dimensionally by means of a piezoelectric actuator such that the probe 9 and the insulation film 10 move relatively. Consequently, the capacitance between the probe 9 and substrate 11 and the variation thereof can be measured in a limited area corresponding to the radius at the tip of the probe 9. Local evaluation of the insulator film 10 can be made arbitrarily based on the capacitance thus measured.

Title: Terminal feeding system
Inventor: KIKUCHI TSUNEO
IPC: H04M19/08
Filed: 1995-06-22
Abstract: PURPOSE: To suppress a rush current at application of power to a telephone exchange system. CONSTITUTION: In the configuration feeding power from a system main body 1 to a terminal equipment 3 via a terminal interface 102, at application of power, a feeding start command signal is sent sequentially from a common control section 104 to each of terminal interfaces 102-1-102-n via control lines L31-L3n, and each of the terminal interfaces 102-1-102-n receives the signal to connect a feeder L4 from a power supply section 105 to each of terminal equipments 3-1-3-n sequentially. Thus, since a rush current is timewise divided and flows little by little, a large amount of the rush current is not supplied simultaneously. Thus, it is not required to design a capacity taking a large amount of rush current into account and the miniaturized power supply is attained with economy.
