Title: Monolithic integration high resolution a/d converter
Inventor: HANSU REOPORUTO
IPC: H03M1/50
Filed: 1990-08-16
Abstract: PURPOSE: To remarkably reduce the number of signal changing times during one evaluation interval so as to improve the precision of a charge-balanced system by forming information as a discrete pulse width to an input-side voltage and generating the output signal corresponding to the information. CONSTITUTION: An input signal V1 is introduced to the input side of a charge- balanced integrator provided with an operational amplifier 10 and a capacitor 2 through a filter 9 and the output of the integrator is inputted to a pulse-width modulator 11. The pulse width of the pulse width-modulated output V0 of the modulator 11 varies depending upon the input voltage. The modulator 11 discretely forms an adjusting quantity from the integrator in the form of a pulse width and the signal V0 is introduced to an evaluation circuit 12 and complementarily controls switches 13 and 14. Therefore, voltages +Vref and -Vref are alternately applied across the feedback input side of the integrator through a resistor 15.  When the input signal V1 is introduced to the amplifier 10, a high-resistance voltage input is obtained against a measuring amount and the operation of a whole converter becomes possible by only using the fed voltage.

Title: Ferrite magnet
Inventor: TAWARA KAZUNORI
IPC: H01F1/11
Filed: 1982-12-08
Abstract: PURPOSE:To maintain both a high IHc and a high Br as a whole by forming several range by ferrite materials having different magnetic characteristics and forming a high IHc region and a high Br region containing materials each having a maximum IHc and a maximum Br. CONSTITUTION:The coercive force of a material 1 is larger than that of a material 2, and IHc1>IHc2 shall be formed. On the other hand, the residual flux density of the material 2 is larger than that of the material 1, and Br2>Br1 shall be formed. High demagnetization resistance is obtained on the starting of a motor because the IHc of the material 1 is larger, and large magnetic flux density is acquired from said magnet by the Br2 value of the material 2. An extent of which the magnet demagnetized by a magnetic field in the lateral direction of an armature increases toward the direction 4 of the arrow from a central section 3 as a high Br section in the case such as a case shown in the figure, but the irreversible demagnetization of a magnet material is prevented while predetermined allowable maximum magnetic field strength can be loaded by combining high IHc members 1.
