Abstract: PURPOSE:To improve a display place by performing homogeneous orientation of 250-290 deg. in twist angle and >=5 deg. in weak electric field tilt angle in the absence of an electric field and adding a dichroic dye in liquid crystal so that a display color is black. CONSTITUTION:Liquid crystal 2 is obtained by adding the black dichroic dye and a rotary polarizing material to the nematic liquid crystal and its spectral characteristics are as shown in a graph; and a characteristic (a) of homogeneous orientation shows good absorption in the almost entire visible range and a characteristic (b) of homeotropic orientation indicates almost no absorption. This liquid crystal 2 is oriented by orientation films 12 and 12 to have spiral structure because of the rotary polarizing material, and is twisted counterclockwise by 270 deg.. This orientation film 12 gives a specific tilt angle between a substrate plane and liquid crystal molecules so as to improve the response and secure bistable characteristics. For the purpose, fluorine is added in high polymer resin to have branches (hand), and consequently variation in partial affinity in liquid crystal molecules is stimulated to perform orientation while increasing the tilt angle. For example, CnF2n+1 is provided in diameter and carboxylic acid is condensed to obtain polyimide resin.

Title: Instrument for measuring floating variable of floating magnetic head
Inventor: ISHII KAZUNORI
IPC: G11B5/588
Filed: 1990-08-23
Abstract: PURPOSE:To make it possible to accurately measure a floating variable even when the variable is >= 2mum by forming a magnetic coil having an opened magnetic path forming an opened end opposed to a disk on a floating slider and detecting the impedance of the coil. CONSTITUTION:A measuring floating magnetic head H is constituted of a floating slider S consisting of non-magnetic ceramics and a solenoid-like magnetic coil C. When a sine wave current is supplied to the winding W2 of the coil C, an induced voltage having frequency equal to that of the current is generated on a winding W1. The level of the induced voltage is determined by the quantity M of magnetic flux passing the winding W1 out of magnetic flux generated by the current supplied to the winding W2. Especially, the quantity M sharply depends upon a distance between the opened end of the coil C and a conductor. When a conductive disk D is used, the distance between the head H and the disk D and its time variation can be detected at high sensitivity by the induced voltage generated on the winding W1.
