Abstract: A display panel module such as a liquid crystal display (LCD) panel module in an electronic apparatus is designed to receive a driving signal of a predetermined frequency. An electrically conductive frame or bezel of the display panel module tends to suffer from the transmission of electromagnetic waves which are related to the wavelength of the driving signal. An electrically conductive member is located behind the display panel and electrically connected to the electrically conductive frame. The electrically conductive member serves to diverge the electromagnetic waves out of the electrically conductive frame. This divergence of the electromagnetic waves serves to suppress the electromagnetic radiation out of the electrically conductive frame.

Abstract: Cooling water is sprayed under a predetermined pressure range and at a predetermined discharge rate over the both surfaces of a sheet to be treated which is reciprocated lengthwise at such a velocity that the product of the reciprocating velocity and thickness of the sheet may be maintained within a predetermined range. The spraying direction of each spray nozzle is individually controlled so that any water remaining over the surface of the sheet may be expelled out. The method and apparatus is especially adapted for use in the normalizing process and in the process for cooling hot-rolled sheet steel.
