Title: Charged beam image-drawing device
Inventor: KUSAKABE HIDEO
IPC: H01J37/305
Filed: 1991-12-26
Abstract: PURPOSE:To stop drawing image when any failure occurs such as microwave discharge and establish pattern drawing free of defect by installing a charged beam sensor etc., in a lens barrel, and therewith sensing the charged beam proceeding in an electron optical lens barrel. CONSTITUTION:An electron beam sensing electrode 41 provided with a hole in the center is arranged between an electron gun 11 and blanking deflector 12 which are installed in an electron optical lens barrel 10, and part of an electron beam in the lens barrel 10 is sensed by this electrode 41. The sensed current flows in a resistance 42 and is taken out in the form of voltage signal, which is amplified by an electron beam sensing amplifier 43 and supplied to a comparator 44. The comparator 44 compares the output from amplification with the upper and lower limits of the allowable values set previously, and if the output goes beyond this allowable scope, the operations of a pattern data generating circuit 31 and a deflection controlling circuit 32 are stopped to interrupt the drawing. Thereby pattern drawing free of defect is achieved.

Title: Fault diagnosis method and device
Inventor: TOYODA TOSHIO
IPC: G01M99/00
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To diagnose faults of many objects to be inspected such as rotary machines different in specifications by orthogonally developing an amplitude probability density function of a measurement signal waveform generated from the objects by Gram-Charlie series. SOLUTION: The method is based on a fact that an amplitude probability density function of a measurement signal such as vibration generated by an object to be inspected such as a machine in a steady state exhibits a normal distribution and it comes out of the normal distribution when a failure or abnormality is encountered. That is, the measurement signal generated by the object is detected, and the amplitude probability density function of an obtained measurement signal waveform is orthogonally developed by Gram-Charlie series to calculate the Gram-Charlie series to diagnose faults of the object. For example, in a fault diagnosis device for frictional faults such as abnormality in bearings, gears, belts or leak, a vibration sensor (contact) measures vibration acceleration in a piezoelectric manner, and a microcomputer performs arithmetic processing and input/output processing of data. Diagnosis results are indicated on a liquid crystal display, as normal, attention or danger.

Abstract: PROBLEM TO BE SOLVED: To provide a wire protection system using a PTC, such that protection of a large-current circuit is achieved by means of a relay and a small-current PTC and the repeated turning on and off of the relay is avoided. SOLUTION: If the circuit of a blower motor 10 has a failed and a resistor 2 is heated to high temperatures, a PTC 1 receives its heat, a transistor 13 is turned off because of the increase in the resistance of the PTC 1, a relay coil 3 therefore becomes nonconductive, a relay contact 4 is turned off, and this off states continues. Even if the temperature of the resistor 2 has dropped resulting in the decrease in the resistance of the PTC 1, this state continues unless an ignition switch 11 is turned on, whereby the repeated turning on and off of the relay contact 4 is avoided.
