Patent JP-H02254997-A (JP)
Title: Inverter control circuit
Inventor: HASEGAWA MASAYASU
IPC: H02P27/06
Filed: 1989-03-24
Abstract: PURPOSE:To enable the correction of motor speed without mechanical modification by providing a speed discriminating means for discriminating whether an inverter device is under acceleration or deceleration or at a constant speed, a supply current detector for an induction motor, an effective value converting means, and a variable gain amplifier, supplying a frequency correcting signal in time of a constant speed, and stopping the supply during acceleration or deceleration. CONSTITUTION:Motor current detected by a current detector 11 is inputted to an effective value converter 12, and converted into a voltage signal by the effective value converter 12. Then, its output is sent to a correction signal outputting amplifier 14, and a frequency setting signal from a frequency setter 4 is also sent to the amplifier 14. The frequency correcting signal is supplied during the motor 2 revolving at a constant speed. But, during acceleration or deceleration the frequency correcting signal outputted by the correction signal outputting amplifier 14 is prevented from being supplied to an inverter device 1 as the contact circuit of a switch 13 is opened by a control signal of the inverter device 1 during acceleration or deceleration. This makes it possible to convert the revolving speed of the motor 2 without mechanical modification.

IPC: G06K17/00
Filed: 1993-03-08
Abstract: PURPOSE:To prevent a memory card from being taken out in its access state and to permit it to be taken out except in the access state by an easy operation. CONSTITUTION:When the access state is set, between a memory card 1 and an apparatus by the control of a general control part 15, an electromagnetic magnet 14 is fed from a magnet feed circuit 16 to turn a stop claw member 10 clockwise. Then, the stop claw 10 enters into a linear guide hollow part 4a, and therefore, a lock part 7c of an eject button 7 is detained by the stop claw 10 and a transmission lever 5 cannot be turned even if the eject button 7 is depressed. When the access state is released, feed to the electromagnetic magnet 14 is broken, and the stop claw member 10 is turned counterclockwise by a coiled spring 13, and the operation of the eject button 7 is not restricted by the stop claw member 10, and therefore, the transmission lever 5 is turned and the memory card 1 is projected from a card storage part 2a together with a card eject plate 3 when the eject button 7 is depressed.
