| 6739099 | Column-and-beam join structure The present invention provides a column-and-beam join structure which absorbs energy caused by a large earthquake or the like by split tees surely yielding at a prescribed value, does not cause other members to fracture, and thus makes it possible to replace only th... | 05/25/2004 |
| 6683487 | Current driver circuit for supplying write current to a write head while changing a flow direction of the write current An H-type bridge circuit includes four transistors, two resistors, and a write head. A write current supplied from a current supply circuit including a first of the transistors and resistors flows through the write head and is received in a current receiv... | 01/27/2004 |
| 6252457 | Differential amplifier circuit Emitters of a first NPN transistor and a second NPN transistor forming a differential input section are respectively connected to collectors of a third NPN transistor and a fourth NPN transistor; the collectors and bases of the third NPN transistor and th... | 06/26/2001 |
| 6222415 | Magneto-resistive element signal amplifying circuit In the bias circuit of a magneto-resistive element signal amplifying circuit, a favorable high frequency characteristic is obtained by suppressing the influence of a parasitic capacitance that is generated. Furthermore, noise is removed by a lowpass filte... | 04/24/2001 |
| 6211736 | Signal amplifying circuit for magnetoresistive element A signal amplifying circuit has a differential amplifying circuit, a capacitor and a voltage follower. This circuit takes as input signal the signals outputted from the two terminals of an MR element to which a bias electric current is supplied, and ampli... | 04/03/2001 |
| 6201421 | Write current driving circuit A write current driving circuit in which drains of the transistors A1 and B1 are commonly connected to the base of the transistor T1, drains of the transistors C1 and D1 are commonly connected to the base of the transistor T2, inverted signal of the input... | 03/13/2001 |
| 6147596 | Vehicle-mounted record medium reproducing apparatus A vehicle-mounted record medium reproducing apparatus having a personal computer function.
