Title: Method for inspecting dc resistance of magneto-resistance head
Inventor: MUKOHARA NORIAKI
IPC: G11B5/455
Filed: 1994-08-17
Abstract: PURPOSE:To automate inspection of a DC resistor of a magneto-resistance head (MR head) by adding a voltage drop detecting circuit to a head tester. CONSTITUTION:The voltage drop detecting circuit 8 consists of two pieces of operational amplifiers 81a, 81b which have high impedances and are connected to both terminals of the MR head 12 and an operational amplifier 82 which is connected to the output sides thereof and outputs the subtracted absolute value. Inspection is executed by procedures of first holding the magnetic head at a suitable height from the surface of a disk and separating the MR head 12 by DC. A bias current I is then passed by a constant current circuit 9, by which a voltage drop is generated. This voltage drop is inputted the operational amplifiers 81a, 81b and the respective terminal voltages E1, E2 of the MR head 12 are detected. These voltages are outputted as the subtracted absolute values by the operational amplifier 82 and the voltage drop E is outputted to a signal processing circuit 73. The bias current I is previously set at a certain value. The ratio E/I of both, i.e., DC resistance R, is calculated from this bias current and the measured voltage E by a CPU 5. This value and a set reference value RS are compared and whether the value is acceptable or not is decided.

Title: Liquid crystal electrooptical device
Inventor: SATO YUZURU
IPC: G09F9/30
Filed: 1989-08-23
Abstract: PURPOSE:To prevent the lowering of contrast and to reduce the cost of a device by setting a light absorbing plate on the surface of a substrate where an opaque electrode consisting of metal is formed which does not contact with a liquid crystal layer. CONSTITUTION:The liquid crystal layer 15 is interposed and held between a 1st substrate 12 where a transparent electrode 11 is formed and the 2nd substrate 14 where the opaque electrode 13 is formed and a polarizing plate 16 and the light absorbing plate 17 are set. An ITO is used as the transparent electrode 11 and nickel is used as the opaque electrode 13, then a black plate is used for the light absorbing plate 17. In the plan of the substrate 14, an oblique line part expresses a picture element and a mesh part expresses a part which looks dark at any time. Since the opaque electrode 13 reflects light passing through the liquid crystal layer 15, an image is displayed by modulating the reflected light by the liquid crystal layer 15. Thus, an effect outside the picture element which is had on display characteristic is mostly removed without providing a light shielding layer in an area other than the picture element.
