Title: Permanent magnet and manufacture thereof
Inventor: NAKAGAWA JUN
IPC: H01F7/02
Filed: 1990-01-26
Abstract: PURPOSE:To make uniform the density of magnetic flux between two magnets when a pair of permanent magnets are used with their different poles opposing with each other by a method wherein the degree of magnetic orientation on the circumferential part is made higher than the degree of magnetic orientation on the center part when the degree of magnetic orientation is measured in the direction of magnetization and in right-angled direction. CONSTITUTION:The arrows in the diagram separately mentioned indicate the direction of magnetization of magnets 1 and 2, and the arrows mentioned between the two magnets indicate the density of magnetization. In ordinary circumstances, a coil is arranged between a pair of magnets 1 and 2. In a moving-coil motor, a current is allowed to flow on the above-mentioned coil, and the coil is moved in right and left directions by the mutual action between the magnetic fields of the magnets 1 and 2. When the degree of the magnetic orientation of the permanent magnets is measured in magnetizing direction and right-angled direction, as the degree of the magnetic orientation of the circumferential part is higher than that of the center part, there is almost no decrease in magnetic flux density between the circumferential parts of the magnets 1 and 2, and the magnetic flux density between both magnets can be kept almost uniform.

Filed: 1981-02-10
Abstract: PURPOSE:To easily exercise DC control on a circuit to be controlled which has nonlinear variation characteristics, by controlling the circuit to be controlled by converting  the output of a pulse-DC converting circuit by a control-voltage characteristic converting circuit. CONSTITUTION:Between a pulse-DC converter 1 and a circuit 2 to be controlled, a control-voltage characteristic converting circuit 3 is inserted. When a potential at the point  D of the converter 1 is lower than that obtained by subtracting the forward voltage  VD of a diode D2 from a potential VF at the point F in the course of variation in a  control voltage at the point B from a 0 to a V1, the D2 conducts and when the potential at the point B is zero, a voltage V2 determined by resistances R6-R8 is developed  at the point D, varying characteristics. When the voltage at the point B is between a VF-VD and a volage VE+VD at the point E, diodes D1 and D2 are cut off and the  voltage at the point B is applied, as it is, to the circuit 2. When a potential at the  point C rises above the VE+VD, the D1 conducts and the voltage at the point B drops  to a V3. When the volages at the points C and D are greater than the VE+VD and less than the VF-VD, linear variation at the point B is applied to the circuit 2 as a control  voltage having nonlinear variation at the point D through the operation of the D1 and  D2.

Title: Floating circuit
Inventor: TAKANO HISAO
IPC: H04B10/50
Filed: 1978-02-21
Abstract: PURPOSE:To form a floating circuit, which can transfer DC and AC signals, with making the power consumption at a no input signal time low and the dynamic range wide. CONSTITUTION:When a positive-polarity signal is inputted to terminal 11, transistors 13 and 14 are turned on and off respectively because the output of amplifier 12 is positive, and only LED 15 of photo coupler 34 is made conductive through resistances 17 and 18 and emits light. Photo detector 23 operates to be made conductive through resistances 26 and 27, and the inversion input voltage of amplifier 25 is lowered to obtain a positive-polarity signal at terminal 33. Thus, photo couplers 34 and 35 are used for positive-polarity signals and negative-polarity signals respectively to be able to make the dynamic range of transfer signals approximately two times as wide as a conventional one. At a no input time, the base voltage is 0, and the luminous element is turned off, and the power of each of elements 14 to 16 becomes 0 approximately. Further, since it is unnecessary to use a capacity in the signal system, DC signals can be transferred.
