A back electrode (,), linear hot cathodes (,) as electron beam sources, and an electrode unit (,) are placed on and fixed to a rear case (,). On the other hand, wire electrodes (,) fixed to a grid frame (,) are positioned relative to stripes of a phosphor screen (,) and are then placed on and fixed to a supporting frame (,) placed in a front case (,) using stud pins (,). According to such a configuration, when the front case and the rear case are bonded and are thus fixed, the position shift between the phosphor screen (,) and the wire electrodes (,) can be suppressed within a tolerance. As a result, a flat-type display apparatus that can display excellent images can be provided.

Flat-type display apparatus with front case to which grid frame with extended electrodes fixed thereto is attached

According to the bonding method of flat electrodes of the present invention, a crystal glass material is arranged between electrodes, heated, and melted while the flat electrodes are pressured, and the melted crystal glass material is fused and re-crystallized to the surface of each flat electrode, so that the flat electrodes can be bonded with strong bonding force. Since a plate-like spacer or an application glass of a low melting point is not used in the method, disadvantages resulting from the spacer or the glass can be removed.

Method for laminating and bonding flat electrodes

A method and apparatus for joining flat-plate electrodes wherein a spacer, to which a joining material such as a low-melting-point crystallized glass containing a crystallization promoting agent is applied, is interposed between the electrodes to be joined. The electrodes and spacer are placed and held between upper and lower attraction dies. The upper and lower attraction dies are placed between upper and lower heating blocks for heating and pressing the electrodes and spacer through the attraction dies to join the electrodes via molten joining material.

Method of joining flat-plate electrodes

A method is disclosed for manufacturing a flat display device including line cathodes arranged at regular intervals, a plurality of flat electrodes arranged so as to be spaced apart by a predetermined distance from one another to control line electron beams generated from the cathodes, and a fluorescent substance which emits a light as a result of a collision of the electron beam. The method includes the steps of: arranging a bar-shaped low-melting glass at a connecting position where the beam generated from the cathode does not pass through; positioning the electrodes and the glass against each other when the electrodes are fixed to connect to the glass; fixing initial connecting portions of the electrodes to the glass, each of which is located outside an outer frame of each electrode; heating and fusing the glass to connect it to the electrodes; and removing the initial connecting portions of the electrodes arranged outside the outer frames of the electrodes from the electrodes.

Method for manufacturing flat display device

A fixed construction for plate electrodes in a flat display unit, wherein holes provided along a common axis through a plurality of plate electrodes have a diameter smaller than that of a tapered insulating pin to be inserted therein, and the peripheral portions of the holes are formed in a thin or tapered construction, thereby supporting and fixing the plate electrodes in position without interposing a spacer and without causing deformation to the areas around the peripheries of the holes formed in the plate electrodes when insulating pins are fitted.

An optical pattern detecting apparatus has a ball lens (2), a light emitting device such as LED (3) and a light receptor such as photodiode (4), the latter two (3, 4) being disposed side-by-side with their optical axis substantially in parallel so that light from the light emitting device (3) passes is converged by the ball lens (2) onto barcode mark (7) and light reflected from said barcode mark (7) is guided by the same ball lens (2) to the light receptor (4); and by use of the ball lens, the apparatus can stably detect the barcode mark even at inclination of the apparatus to the surface of the barcode mark.

Optical pattern detecting apparatus

An image display apparatus provided with wire electron sources, electron beam control electrodes for controlling the electron beam emitted from the electron sources, electron beam deflecting electrodes for deflecting the electron beam, electron beam accelerating electrodes an electron beam light-emitter which emits light when struck by an electron beam, and an evacuated enclosure having a transparent face at which the light-emitter is positioned and enclosing the electron source and electrodes, at least the electron beam accelerating electrodes being electrodes which are adapted to be deformed when subjected to a Coulomb force to a predetermined beam position, thereby eliminating the adverse effect on the image due to deformation of electrodes cause by the Coulomb force generated when each electrode has a voltage applied thereto.

Image display apparatus with deformable accelerating electrodes

A disclosed method of continuous making flexible printed circuits for use in radio set or the like appliances, includes punching holes in a continuous copper-film clad insulating substrate, forming photopolymer films on the faces of the copper films exposing the photopolymer film to photochemical light of a predetermined pattern, developing the exposed photopolymer film, etching the copper film utilizing remaining parts of the photopolymer film as etching masks, removing the remaining photopolymer films 40 and printing solder-resist films on selected parts. The improvement is to provide and retain selected oblong parts of said conductor metal film disposed on and parallel to longitudinal direction of the continuous substrate by, for example, covering these parts by etching-resist films. The retained oblong parts of the metal film serve to prevent shrinkage of the substrate during the conduct of further manufacturing steps thereby assuring registration of the patterns of the printed circuits and the printed solder-resist films.
