Title: Multigap magnetic head
Inventor: ABE MITSUO
IPC: G11B5/29
Filed: 1989-03-15
Abstract: PURPOSE:To minimize a output loss by forming the shape of the sliding surface of the multigap magnetic heads disposed with plural gaps on the sliding surface to the assemblage of projecting curved surfaces, the vertexes of which are respective gap positions and setting the ridge lines of the respective curved faces in the direction in contact with plural pieces of virtual ellipses. CONSTITUTION:The positions of the gaps 3a, 3b in the sliding surface of the head are the parts projecting most to a tape 20 side and, therefore, if the magnetic head is slid in the state of pushing the head to the magnetic tape 20, the contact pressure with the tape 20 is maximized and the spacing quantity is minimized to minimize the output loss. The positions of the ridge lines 12a, 12b in the sliding surface are next larger in the pressure and the tape 20 is extended along the ridge lines 12a, 12b and receive deformation. Since the ridge lines 12a, 12b are aligned to the tangent of the virtual ellipse 14, the deformation of the tape 20 builds up in the shape which is like a contour line 16. The ellipse 14 is formed symmetrical with respect to the sliding axis 10 by selecting the aspect ratio thereof so as to minimize the area thereof and, therefore, the area of the deformed part is minimized and the tape 20 slides smoothly without having torsion.

Title: Bias circuit
Inventor: MURAYAMA AKIHIRO
IPC: G05F3/30
Filed: 1988-03-14
Abstract: PURPOSE:To reduce the variance of an output voltage caused by beta of a transistor and a resistance by changing a transistor base - emitter voltage (Vbe) multiplying circuit to a negative feedback circuit so that the output voltage can be outputted equivalently by an emitter follower. CONSTITUTION:An output current I0 of a band gap type constant-current source 1 almost all passes through a Tr Q1 and flows to a resistance R2. To the resistance R2, a current of Vbe/R1 flows. This current and a base current of the Tr Q1 are supplied by a Tr Q2. An output voltage can be set separately from a temperature dependency in the same way as before. The Tr Q2 is an emitter follower, and can output a constant-voltage by a low impedance. Also, a current flowing through the Tr Q1 is not varied against a variance of a resistance R1, but constant as I0. Accordingly, the Vbe of the Tr Q1 is scarcely influenced by the variance, and the output voltage is also strong against the variance. Since the base current of the Tr Q1 is allowed to flow by the Tr Q2, the influence against the output voltage decreases remarkably.
