Title: Electrically oscillating type dc motor
Inventor: NAKAMARU SHINOBU
IPC: H02P6/08
Filed: 1979-08-27
Abstract: PURPOSE:To enhance the power efficiency of the DC motor by constituting an electric circuit in the form of electric oscillation characterized by the smooth repetition of an instantaneous current and maintaining the resonating state. CONSTITUTION:Field coils L4 and L7 have windings of the same polarity and the number of winding in the reverse directions, and serve as the third pole with respect to the other field coils L5 and L6. Capacitors C6-C8 are located in-between the poles of the three field coils. Since there are three pairs of L and C, three AC forming circuits are required, but only one circuit is shown in the Figure. At the time the current flows in the order of X1-X6; the ON operations of two pairs of thyristors S1, S2, and S3, S4 are repeated; and the driving current increases in proportion to the high voltage across the capacitor. At the time of no load, since the number of rotation increases, the off control of the thyristors in the negative side is accelerated with respect to the positive side, the transient current is absorbed by diodes D5 and D6, charging is stopped, and the very weak current has resulted. When the load is given, since the number of rotation is decreased, the conductive period is lengthened.

Title: Non-volatile semiconductor storing device
Inventor: KOBAYASHI SHINICHI
IPC: G11C16/02
Filed: 1990-04-24
Abstract: PURPOSE:To suppress the dispersion of the threshold values of a memory cell at the time of erasing the contents of the cell even when the erasing characteristics of the cell are dispersed by deciding the end of erasing between two different thresholds, impressing a writing voltage after impressing an erasing voltage, and then impressing the erasing voltage again. CONSTITUTION:Erasing is executed up to a point (T2) of time when a curve (a) is dropped lower than Vth max, a Vth min is checked, and when no memory drops lower than the Vth min at the point of time, erasing is completed at the point of time. If a curve (b) is dropped lower than the Vth min at the T2, a high voltage is impressed to the control gates of all memory cells and a high electric field is impressed between a substrate 7 and a floating gate 1 to increase the threshold values of the memory cells up to a certain level. Thereby, a difference between the threshold of the memory indicating the characteristics of the curve (a) and that of the memory indicating the curve (b) is reduced as compared with a difference at T1. Then a high voltage is impressed to the sources or drains of the memory cells to erase the contents of the memory. Consequently, the dispersion of the thresholds of memory cells at the time of erasing can be suppressed to a low level and stable yield can be obtained.

Filed: 1980-08-11
Abstract: PURPOSE: To eliminate distortion generated at the rise and the fall of an output pulse, by superposing a part of the output signal of a step signal source onto the output signal with an opposite polarity.  
     CONSTITUTION: When the voltage applied to terminal 13 changes from -1V to 0V, diode CR 2  is turned on to charge capacitor C. Simultaneously, a positive- direction distortion voltage is generated at terminal 15, and the inter-terminal voltage of capacitor C changes at a certain rise time after. Collector voltages of transistors 19 and 27 change similarly, and these collector voltages change rapidly in the negative direction. At this time, the base terminal voltage of transistor 27 changes from 0V to -1V, and the collector voltage changes in the positive direction by a quantity determined by resistance R 3  and current source I 2 . Consequently, positive and negative changes cancel each other to prevent distortion from being generated.

Abstract: PURPOSE:To prevent noise from being mixed in a transmission system using a coaxial cable. CONSTITUTION:Noise removal units U1 and U2 are arranged between relay amplifiers R1 and R2, which are respectively provided on both ends of a coaxial cable C1, and in the units U1 and U2, one pair of parallel lines 21 and 22 are wound on an annular ferrite core in the same direction to constitute a coil. In this circuit, as the values of self inductances L11 to L22 are large enough, the inductances of earth feedback closed circuits are decided by those inductances and become an equal value. Noise currents are respectively made to flow through both earth feedback closed circuits by a change of magnetic fluxes with time to penetrate both earth feedback closed circuits, but as the inductances of both earth feedback closed circuits are equal to each other, the noise currents, which are respectively made to flow through both earth feedback closed circuits, become equal to each other and a signal voltage between a core conductor 11 and an outer conductor 12 is not affected by these noise currents. As a signal current is induced so that the magnetic flux of a core becomes 0, it is not exerted the effect of this device.
