Title: Liquid crystal display device
Inventor: KUGO MASARU
IPC: G02F1/1335
Filed: 1985-04-12
Abstract: PURPOSE:To improve outward appearance and visibility by outputting different liquid crystal driving voltage waveforms to a variable color display part and a fixed display part. CONSTITUTION:A rectangular wave pulse having a 50% duty ratio is inputted to one-side input terminals of two exclusive OR circuits 31 and 32 in common and a pulse signal is inputted to a common side terminal 33 as well. A signal from the circuit 31 is inputted to a segment side electrode 34 for fixed color display between output terminals of the circuits 31 and 32 and a signal from the circuit 32 is inputted to a segment side electrode 35 for variable color display. Output voltage values of the circuits 31 and 32 are different; the circuit 31 outputs +V1 and the circuit 32 outputs +V2. The distance between electrodes is equal and a liquid crystal material 17 is also the same. Consequently, the visibility is improved.

Title: Leveling device
Inventor: KONNO YOSHISHIGE
IPC: G01B21/22
Filed: 1991-03-15
Abstract: PURPOSE:To prevent change of a mounted matter on a mounting part by providing a regulating means for preventing rotation of the mounting member to a base plate about an axial line of a straight line connecting two portions of a first support member supporting the base plate and the mounting member with each other. CONSTITUTION:Where outputs of changeable means 4, 5 are different from each other, a relative rotation is generated between a ball and a pillow block of a support body 7 for keeping an interval between a base plate 2 and a mounting part 3 constant by action of the differential force quantities, and a relative rotation occurs between the base plate 2 and the mounting member 3 in a direction of an arrow E. A slider 24 is held on the side of the base plate 2, while a spherical roll 22 is pivotally supported on the side of the mounting member 3, so if a relative rotation is occurring, a pressure between the spherical roll 22 and a groove 15 of the slider 24 operates to regulate the rotation. The mounting member 3 is thus rotated only in the directions of arrows A, B to the base plate 2. If an inclination is corrected for the mounting member 3 to the base plate 2, therefore, a position change caused by other than an attitude control will not occur for a mounted matter mounted on the mounting member 3.
