Title: Recording/reproducing device
Inventor: SAITO HITOSHI
IPC: G11B17/32
Filed: 1987-10-22
Abstract: PURPOSE:To equalize pressing force applied on a magnetic head and to stabilize the touching of a head by providing a rugged parts on the upstream side of a slider in the recording medium rotating direction and on the downstream side of the same to generate a negative pressure between the slider and a rotating recording medium. CONSTITUTION:When the elastic recording medium D rotates, a negative pressure is generated on the top surface of the furthermost upstream one 7 of the projecting stripes 7-10 provided on the slider 2 because the clearance between the said surface and the lower surface of the recording medium D gradually comes wider toward downstream at an angle beta2, and the medium D curves downward at the place of the projecting stripe 7. The recording medium D curves because of negative pressure at the stripes 8-10, on the other hand, since a positive pressure is generated at the furthermost upstream and downstream projecting walls 6a, the magnetic medium D curves almost symmetrically on the upstream side and the downstream side with a magnetic head 1 in the center of the symmetry. Hence the negative pressure to press the medium D downward works respectively at two positions on the upstream side and the downstream side of the medium D, which stabilizes the touching of the head.

Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a logic gate using two negative resistive elements by connecting a FET in parallel with a 1st negative resistive element and connecting a 2nd FET in parallel with a 2nd negative resistive element. SOLUTION: In the embodiment, when a gate-source voltage of a transistor(Tr) T1 is the same as 0V, a current flowing to a source-drain of the Tr T1 is equal to a source-drain current of a Tr T2. A source and a gate of the Tr T2 are connected so as to set a source voltage equal to a gate voltage at all times. That is, the Tr T1 and T2 are set to a state that a gate-source voltage of the Tr T1 is equal to zero. Thus, when conventional depletion Trs are adopted for the Trs T1, T2, a current flowing to the Tr T2 is the same as a current flowing to a negative resistive element D1 for offset of the Tr T1.
