Title: Current sensor
Inventor: WATANABE YOSHITAKA
IPC: G01R15/18
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a current, sensor capable of having a measuring range in a wide band with high precision and corresponding to various wires to be measured from a small diameter to a large diameter. SOLUTION: An insulation resin 12 is coated over the whole periphery of a core 11 and a conductor foil 13 is formed on the circumference. An outside face part 13c of the conductor foil 13 enables a line of slit 13s to go around, and an insulation area is formed by exposing the insulation resin 12. The conductor foil 13 functions as a roll of winding for the core 11, and output accompanying in-core hole penetration current is obtained by connecting lead wires 15, 15 to the arbitrary part of both the ends 13c, 13c respectively. Influence reduction of ideal low inductance and skin effect is achieved, by making the winding the very wide foil and winding it around the core in wide area, the wide band of the measuring range is achieved and the current sensor has the advantage of being hardly depending on the position of the wire to be measured in the core hole.

Title: Random number seed generating circuit, driver provided with the same and sd memory card system
Inventor: ARAI YOSHIHISA
IPC: G06F7/58
Filed: 2001-03-07
Abstract: PROBLEM TO BE SOLVED: To change a random number seed without a non-volatile memory whenever an operation is started. SOLUTION: An oscillator 14 is operated immediately after power source supply and generates a high speed clock. A counter 15 is operated by the high speed clock and changes a count value into the high speed one. In the meantime, a power-on reset circuit 10 outputs a power-on reset signal which indicates that an internal power source is made to be stable when a sufficient time elapses after power source supply. The power-on reset signal is sufficiently slower than the high speed clock and a period for an input to a latch circuit 16 is various. Then the count value (the random number seed) to be latched by the latch circuit 16 becomes different whenever the power source is supplied. A random number is generated through the use of the random number seed.
