Title: Initial setting system for system variable
Inventor: ISHIDA TOYONORI
IPC: G06F1/00
Filed: 1988-04-01
Abstract: PURPOSE:To prevent a computer system from being started with an illegal variable by checking a comparator at the time of the startup of the computer system without fail, and initializing system variables in a nonvolatile memory unless a reference voltage is reached. CONSTITUTION:The comparator 3 compares the reference voltage Vs of a reference voltage generation source 2 with the voltage Vx of a power source 1 to output '0' when Vx>Vs or '1' when Vx<=Vs. A register 4 is a register which can be read by a CPU at all times and its comparison bits correspond to the output of the comparator 3. Then the comparator is checked at the time of the startup of the computer system without fail and when the voltage Vx of the power source 1 does not reach the reference voltage Vs, it is considered that the contents of the nonvolatile memory are illegal, thereby initializing the system variables. Consequently, the computer system is prevented from being started with an illegal system variable.

Title: Method and apparatus for nondestructive measurement of quenched and hardened range
IPC: G01N27/80
Filed: 1992-03-02
Abstract: PURPOSE:To measure the quenched and hardened range of a ferromagnetic-substance material with good sensitivity, clearly and in a nondestructive manner by a method wherein the average signal level of a Barkhausen effect noise in a quenched part and a non-quenched part at a partially quenched material is compared with a reference voltage. CONSTITUTION:A secondary-voltage signal which is generated across both ends of a detection coil 2 is passed through a bypass amplifier 6. Only a BN signal as a high- frequency component is amplified (a voltage V1); after that, it is inputted to a detection and rectification circuit 7; the positive component of the BN signal is smoothed. The obtained signal level (a voltage signal V2) of the BN signal is compared with a reference voltage VS by means of a comparison circuit 8. When the signal V2 is larger than the voltage VS, the output voltage signal V3 of the circuit 8 is set to a high level. In the opposite case, the signal is set to a low level. When the signal V3 is at the low level, a quenched part (a) is detected. When it is at the high level, a non- quenched part (b) is detected. A position where the V2 is changed from the low level to the high level or in an opposite case indicates the quenching boundary between the quenched part (a) and the non-quenched part (b).
