Title: Key operation discriminating method and key operation discriminating circuit
Inventor: KURAMOTO MAKOTO
IPC: H01H9/54
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To correctly discriminate a number of key operations. SOLUTION: The power is supplied from a power source part 11 to a microcomputer 20 via a diode 12. When the power is not supplied from the power source part 1 to the microcomputer 20, the power is supplied from a backup power source 30. The power supplied to the microcomputer 20 is supplied to an operation key part 45 via a transistor 51. The power supplied from the backup power source 30 to the operation key part 45 is blocked by transistors 51, 53. In the operation key part 45, a key signal of the voltage level corresponding to the key operation is produced by using the supplied power, and transmitted to an input terminal 22 of the microcomputer 20. In the microcomputer, the operated key is discriminated on the basis of the voltage level of the transmitted key signal.  Since the voltage level of the key signal transmitted to the microcomputer 20 changes interlocked with the fluctuation of the voltage level, even if the power source voltage level of the microcomputer 20 fluctuates, a number of operation keys can be discriminated correctly.

Title: Method for detecting abnormality of arc rocking amplitude in narrow groove gma welding
Inventor: WATANABE HIROSHI
IPC: B23K9/095
Filed: 2000-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting an abnormality of arc rocking amplitude in narrow groove GMA welding capable of automatically detecting the abnormality of arc rocking amplitude to easily save manpower and improve quality. SOLUTION: Whether the abnormality occurs in the rocking amplitude of an arc 7 or not is automatically judged by comparing the difference of a welding current value or the difference of a welding voltage value when the rocking position of the arc 7 exists in the left and right zones and when it exists at the central zone with a reference value. Thus, since the wear progress of a power feeding chip 2 and the generation of a failure of a wire oscillator 11 are quickly and automatically detected, periodic or continuous monitoring by an operator is not necessitated, the power feeding chip is exchanged at a suitable time, a troublesome adjustment concerned about in the case of continuing defective welding is also avoided, and unmaned welding for a long time is allowed.

Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a forced air-cooled main motor for a vehicle, capable of coping with acceleration of a train by reducing the size and weight and increasing the rating. SOLUTION: A substantially trapezoidal heat shielding cylinder 12 is fixed at its base end to an inside of a side frame 1b of a stator 1A.
