Title: Fixing structure of square core
Inventor: INAGA KENGO
IPC: E05B3/04
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To firmly fix a square core inserted in a square hole by a method wherein an elastic member is disposed between the square hole and the square core and the square core is pressed from two directions through the force of the elastic member. SOLUTION: Elastic members 10 are arranged on the horizontal surface and the vertical surface of the square hole 41 such that a square hole 41 is made narrower in the two directions of a horizontal direction and a vertical direction. When a square core 4 is inserted in the square hole 41 in which the elastic members 10 are arranged, a force to cause movement of the elastic members 10 in the advancing direction of the square core 4 is applied. However, since a lock piece 11 is brought into abutment against the end face of a hub 40, the elastic members 10 are prevented from displacement in a position. The square core 4 inserted in the square hole 41 deforms the arcuate elastic member 10 into a flat state and the square 4 is pressed in a direction in which no elastic member 10 is arranged.  As a result, the square core 4 is pressed in a vertical direction and a horizontal direction and the square core 4 and a hub 40 firmly fixed both in a vertical direction and a horizontal direction.

Filed: 1982-05-19
Abstract: PURPOSE:To make the distribution of magnetic flux steep to the tip of a thin plate shape soft magnetic body and to attain high density writing, by fitting a metal of good conductor to the head of a magnetic head for writing for a vertical magnetic recording system except an opposing surface of the tip to a recording medium. CONSTITUTION:A metal 33 of good conductor (e.g., copper) having 10mu thickness (c) is fitted to a thin soft magnetic substance 31, for example, of 2.5mu thickness (a) and 2mm. wideness (b) by sealing or vapor-depositing methods. Writing is made by touching the tip with the metal 33 on a recording medium. When a magnetic flux in high frequency passes through the metal 33, an eddy current is produced in the metal 33 and the magnetic flux is canceled, then the magnetic flux is made incident only to the recording medium opposing surface of the magnetic substance 31 and the distribution of magnetic flux to the tip of the magnetic substance 31 is made steep. Thus, high-density recording can be made and a high output can be obtained at reproduction.

Abstract: PURPOSE: To suppress spurious radiation from an AM stereo receiving circuit to other circuits, by making the limiter of the AM stereo receiving section inactive other than in the reception of te AM stereo, and controlling a voltage controlled oscillator in a PLL circuit for subsignal detection.  
     CONSTITUTION: The inverse input of a limiter 1 is grounded when FM position is taken other than AM with a function switch S 1 , and the DC balance of differential input is unbalanced. Thus, the limiter 1 stops an amplification and limiter operation and makes it inactive.
