Filed: 1980-12-29
Abstract: PURPOSE:To exactly detect drop of DC supply voltage, and to exactly protect the storage contents of a memory, by inputting DC supply voltage to one input terminal, and using a comparator output obtained by delaying siad voltage and inputting to the other terminal, as a memory selective signal. CONSTITUTION:Voltage of DC supply boltage Vcc is directly inputted to one input terminal, and also an output of a comparator 3, which has been inputted through a delaying circuit 2 to the other input terminal is used as a memory selective signal, and is inputted to an IC memory 1. In this case, the circuit 2 is formed by a resistance R and a capacitor C so that attenuation is not generated substantially, and when voltage of an electric power supply Vcc is varied, an output of the circuit is also varied accordingly. Therefore, the comparator 3 generates an output when the voltage of the electric power supply Vcc has started to drop, and it is inputted to the memory 1 as a memory selective signal for cutting off an input. In this way, a drop of DC supply voltage due to a fault of an electric power supply is detected exactly, and storage contents of the memory is protected exactly.

Title: Permanent magnet motor
Inventor: SUGIURA KENJI
IPC: H02K1/28
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To suppress vibrations in the thrust direction of a rotor core. SOLUTION: A rotor core 2 is formed in a structure, in which the core 2 is not brought into contact with a stator 1 by a shaft 3. Since the shaft 3 is loosely engaged with the core 2, the shaft 3 can move freely in its thrust direction. Thus, even if a magnetic field for moving the core 2 in the thrust direction is generated by the stator 1, only the core 2 is moved, its movement is not transmitted to the shaft 3, and a vibration of a fan mounted at the shaft 3 is suppressed.
