Title: Low band noise eliminating circuit
Inventor: YOKOYAMA KENJI
IPC: H04B1/10
Filed: 1984-06-20
Abstract: PURPOSE:To eliminate low band noise such as rumble noise, etc. without deteriorating a low band characteristic, by extracting a high band component and a low band component from the input signal of each right and left channel, mixing the right and left low band components, adding them to each high band component, and outputting them. CONSTITUTION:High band components of right and left channel CH signals from a stereo record inputted from terminals 10, 12 are extracted by HPFs 14, 20, respectively, and the low band components are extracted by LPFs 16, 18, respectively. Cut-off frequencies of each HPF14, 20 and LPF16, 18 are set to the same. The low band components extracted by the LPFs 16, 18 are added and mixed by an adder 22, and its output is added to the high band components from the HPFs 14, 20 by adders 24, 26, respectively, and outputted to each CH of the right and left. The noise such as rumble, etc. in the low band components from the LPFs 16, 18 has no correlativity in phase, therefore, it is averaged by the adder 22 and suppressed, and since a normal signal has a correlativity, it is increased by the adder 22, added to the high band component of each CH of the right and left, and outputted, therefore, the low band characteristic is not deteriorated.

Title: Method of controlling motor speed
Inventor: CHINO TOSHIHIKO
IPC: H02P29/40
Filed: 1989-05-22
Abstract: PURPOSE:To stable motor speed control by making the proportional gain of a speed controller variable according to the magnitude of the moment of inertia of a load applied to a motor. CONSTITUTION:At the place such as, e.g. a process line, where a high accuracy tension control is required, various sections are in a line and distances between rolls 7 for carrying a strip 8 are also various. Consequently, a load applied to each motor 5 varies with every roll 7 and its moment of inertia also varies naturally so that the speed response of each load changes and a change of tension occurs at the time of acceleration and deceleration of said line to press said strip 8 or cause the strip to move in a zigzag direction in the worst case. Therefor, the proportional gain of the speed controller of said motor 5 is made alterable from the outside and the proportional gain of said speed controller is made variable according to the magnitude of the moment of inertia of the load being applied presently. Thus, the speed response of said load can be made almost constant independent of a change of the magnitude of the moment of inertia of the load so that the stable speed control of said motor 5 can be performed.

Abstract: PURPOSE:To reduce a leakage magnetic flux, by making one of both magnetic cores placed in a butted part a protruded part and making the other magnetic core, a recessed part, and by inserting the protruded part into the recessed part, and by providing tapered surfaces on the protruded and recessed part, and further, by making the formation angles or curvatures of both the tapered surfaces equal to each other. CONSTITUTION:A ferrite magnetic core comprises two E-shaped ferrite magnetic cores 1, 2, whose central legs 3, 4 are both cylindrical. The end of the central leg 3 is made to be a cone-like recessed part 5, and the end of the central leg 4 is made to be a cone-like protruded part 6. The formation angles of the cone-like parts of the respective central legs 3, 4 are made equal to each other. Thus, in the gap part between both the cone-like parts, the central leg 4 is inserted into the central leg 3, and therefore, the leakage magnetic flux of the ferrite magnetic core is made less. Also, by adjusting the length of the gap, a desired DC superposition characteristic can be obtained. Further, since the ends of the recessed and protruded part are both pointed, they can be cut satisfactorily.
