Inventor: KANEKO KENJI
IPC: G11C11/416
Filed: 1981-10-19
Abstract: PURPOSE:To facilitate writing and to speed reading by reducing a current flowed from a word line on the injector side of an integrated injection logical element during information writing to a memory cell, and increasing the current during information reading. CONSTITUTION:A memory cell C1 of I<2>L is equipped with word lines W1 and W2, bit lines B0 and B1, an NPN transistor (TR) N1 for driving the word lines, a constant current source CS1 for holding the information of the memory cell, and an AND circuit G1 for driving the NPNTRN1. A word line selection signal is inputted to an input A of the AND circuit G1 to select a word line at a high level. A write-read switching signal is applied to an input B to perform reading at the high level or writing at a low level. During writing, the TRN1 turns off to reduce the word line current, facilitating the writing. During reading, the TRN1 turns on to increase the word line current, realizing high-speed reading.

Abstract: PURPOSE:To obtain the gradient magnetic field amplifying device being small in size and light in weight which can photograph an arbitrary cross section by an echo planner imaging method by connecting outputs of two amplifiers whose output waveforms are different to the respective windings of a gradient magnetic field coil of a bifilar wind, and also, connecting a cancel coil to the gradient magnetic field coil. CONSTITUTION:In order to couple an output of an amplifying device of a resonance type consisting of voltage amplifiers A1, A2 and a capacitor C and an output of a transconductance amplifier of a linear type as a gradient magnetic field waveform, a gradient magnetic field coil 30 of a bifilar wind is used. However, in the case of using it only, induced electromotive force M (d11/dt) caused by an output current 11 of a voltage amplifier 16 is generated on the side of windings L2, r2. In the same way, induced electromotive force M (dI2/dt) caused by an output current 12 of a linear amplifier is generated on the side of windings L1, r1. Therefore, in the case of a state as it is, there is possibility that damage is given to the voltage amplifiers A1, A2, and the transconductance amplifier Gm2 is broken down, therefore, the influence of induced electromotive force is compensated by connecting a cancel coil 34 of a bifilar wind in series to the gradient magnetic field coil 30.

Filed: 1990-06-26
Abstract: PURPOSE:To suppress regenerative power by maintaining the frequency of an inverter constant when an overvoltage protective circuit consumes regenerative power of a motor thereby matching the signal of the inverter with r.p.m. of the motor. CONSTITUTION:Frequency signal from an inverter circuit lowers in step when a deceleration mode is being set and when an overvoltage protective circuit 22 detects regenerative power produced in a motor, a signal is provided through a photocoupler 43 to a microcomputer 8. When the signal is being provided, the microcomputer 8 releases the deceleration mode and maintains the frequency signal from an inverter circuit 7 at a constant level. Consequently, r.p.m. of the motor matches with the frequency signal from the inverter circuit and thereby regenerative power is suppressed.
