Abstract: Through holes (104) formed in an electrical insulating substrate (102) having adhesive layers (101) on its both surfaces are filled with a conductor (105). Then, supporting bases (106) having wiring layers (107) with a predetermined pattern are laminated on both the surfaces of the electrical insulating substrate (102), which are then heated and pressurized. After that, the supporting bases (106) are removed, thus obtaining a circuit board in which the wiring layers (107) have been embedded in the adhesive layers (101). The conductor (105) within the through holes (104) are compressed sufficiently, thus forming minute via holes with high reliability.

Abstract: Ink images are prepd. by (1) forming a composite of (a) a printing plate with ink receptive and ink repelling areas, (b) a heated thermosensitive ink layer, and (c) a resin sheet; (2) cooling the composite; and (3) peeling the printing plate and resin sheet apart so that the ink present is the ink repelling areas of the printing plate transfer to the resin sheet.

Abstract: Liquid crystal display elements formed at intersections of strip-shaped X-electrodes and Y-electrodes are actuated so as to display images. The liquid crystal mixture used consists essentially of a nematic liquid crystal having a positive dielectric anisotropy, a nematic liquid crystal having a negative dielectric anisotropy and a steroidal compound of a certain group. This liquid crystal mixture has a threshold value and is light-transparent upon application of a voltage above said threshold value. Each of said X-electrodes is sequentially addressed by an addressing pulse having a pulse height of about 2V and as biased by a d.c. bias voltage bias V from a standard level and having a duration Tw, said d.c. bias voltage V being below said threshold value. A signal pulse is supplied to each of said Y-electrodes, said signal pulse having a polarity opposite to that of said addressing pulse and a duration up to Tw and being biased by a d.c. bias voltage 2V from said standard level.

Abstract: A matrix display device having a liquid crystal display element at each of the intersections of horizontal parallel strip shaped X-electrodes and vertical parallel strip shaped Y-electrodes. Each display element is excited by an X-address pulse applied to an X-electrode and a Y-signal applied to a Y-electrode for producing an image. The liquid crystal has a threshold voltage in a.c. operation above which the liquid crystal exhibits a change in transparency.
