A cathode ray tube, comprising a front panel glass having a fluorescent screen; a glass envelope sealed with the front panel; a film having a conductive layer and an insulating layer superposed on the outer side of the front panel glass; a plurality of ground electrodes soldered on the film by using a soldering iron which has an ultrasonic wave generator; and a conductive layer connected with the ground electrodes electrically through the insulating layer, and a method for manufacture of the same.

Cathode ray tube and method of manufacturing the same

Disclosed herein are adhesive compositions for use in cathode ray tubes comprising a specified epoxy (meth)acrylate, hydroxyl-containing mono (meth)acrylate, a photopolymerization initiator and optionally an urethane (meth)acrylate, the cured products thereof as well as cathode ray tubes obtained by the use thereof. The adhesive compositions of the present invention are excellent in spreadability and the resulting cured products have a good adhesion to glass. Cathode ray tubes in which a sheet of film is bonded to panel-glass by using an adhesive of the present invention exhibit satisfactory screen states comparable to those exhibited by cathode ray tubes subjected to a polishing process.

CRT adhesive composition and CRT obtained by the use thereof

A cathode-ray tube apparatus (CRT) including a panel glass which has been subjected to no external polishing, and an ultraviolet-curing resin layer provided on the panel glass and having a refractive index which differs from that of the panel glass by not more than 0.8%. The CRT further includes a light-transmitting film provided on the resin layer. Also disclosed is a production method which enables a reduction in the weight of a CRT and an improvement in the explosion-proof performance, which have been demanded with the realization of large-sized CRTs and flat-panel CRTs, and which also makes it possible to produce such CRTs by a simplified process and at a reduced cost.

Method of producing transmissive screens

A method of producing a resin mold that includes the steps of pouring a first resin into a metal mold, curing the first resin at a first temperature thereby making an intermediate resin mold made of the first resin, separating the intermediate resin mold from the metal mold, pouring a second resin into the intermediate resin mold, curing the second resin at a second temperature thereby making a final resin mold made of the second resin and separating the final resin mold from the intermediate resin mold, wherein by selecting the first and second curing temperatures of the first and second resins, the final resin mold will have the same size as that of the metal mold.
