Title: Digital filter
Inventor: HATANAKA NAOYUKI
IPC: H03H17/02
Filed: 1987-09-22
Abstract: PURPOSE:To optimize both the speed and the quantity of hardware by approximating the tap gain in a form of the sum of 2's power so as to apply arithmetic operation to a signal with a small bit shift difference earlier in a digital filter not requiring a multiplier and a ROM table. CONSTITUTION:Signals with small bit shift difference are selected among plural signals subject to bit shift included in one and same stage to apply addition/ subtraction and the sum of the bit shift differences over the entire stage is minimized. For example, in realizing a digital filter expressed in the transfer function as shown in, e.g., equation I, the equation I is modified into equation II and at first the operation of the 3rd term and the operations of the 1st and 2nd terms are executed in parallel. That is, in the operation of the 3rd term in the equation II, after the operations of A=Z<-1>+Z and B=Z<-3>+Z<3> are executed in parallel, the operation of C=A-B is executed. Moreover, in the operation of the 1st and 2nd terms in the equation II, the operation of D=Z<0>+A/2 is executed after the execution of previous operation of A=Z<-1>+Z is awaited, and the operation of (D+C/16)/2 is calculated finally.

Patent JP-S6391810-A (JP)
Title: Production of magnetic head
Inventor: INO KAZUO
IPC: G11B5/127
Filed: 1986-10-06
Abstract: PURPOSE:To decrease a nonmagnetic layer at the joint surfaces (boundary faces) of a magnetic metallic material and ferrite core by specifying the butt pressure F of a pair of ferrite core half bodies and subjecting said bodies to glass welding. CONSTITUTION:The generation of a pseudo gap at the boundary faces 5 depends largely on the butt pressure of the ferrite core half bodies (including the case of a wafer). The stress level at the boundary face is not so much increased and the nonmagnetic layer is hardly generated by the heat treatment effect of 'Sendust(R)' and ferrite even if the core half bodies are held at a high temp. when the butt pressure is decreased. The diffusion of oxygen atoms at the boundary faces is suppressed if the butt pressure is set at <=2kg weight/mm<2>. The production of the heads at a high yield is permitted with easy control of the flatness if the butt pressure is set at >=0.2kg weight/mm<2>. The optimum butt pressure F is, therefore, 0.2<=F<=2.0kg weight/mm<2>.
