Abstract:
A voltage applying apparatus including a holder, a probe and the like as voltage applying means enabling the application of a voltage to electrode wiring connected with electric conductors formed on a substrate on which the electrode wiring is formed. The apparatus is equipped with aligning means making the position of the probe follow to the changes of the position of the electrode wiring to coincide with them. The aligning means makes the position of the probe follow the position of the electrode wiring so that the probe aligns the electrode wiring by the thermal expansion of the holder.
Abstract:
In an apparatus for performing heating treatment of a structure composed of a substrate and a structure arranged on the front surface of the substrate, the latter structure having thermal capacity smaller than that of the substrate, heaters are arranged to be opposed to the front surface and the back surface of the substrate, respectively, and a cooling body is arranged at a position opposed to the back surface of the substrate to sandwich the heater of the back surface between the cooling body and the substrate. Thereby, the heating and the cooling of the substrate are performed rapidly to shorten the time of a heating process, and the deformation and the damage of the substrate at the time of heating are prevented.
Abstract:
The present invention provides a method of effecting high temperature vacuum heating and cooling suitable for conducting heat treatment to be performed on components used in a display apparatus. The present invention's heating/cooling method comprises the steps of: heating a plate-like member placed in a reduced pressure atmosphere in a chamber by heating means opposed to the plate-like member; and cooling the plate-like member by a cooling plate which is opposed to the plate-like member, with the heating means therebetween, the cooling plate having a heat reflecting function. In one aspect of the present invention, the cooling plate is designed to have a emissivity of not less than 0.50 but not more than 0.80 so as to minimizes a sum of a requisite time for the heating step and a requisite time for the cooling step. In another aspect of the present invention, the plate-like member to be heated has two main surfaces differing from each in an in-plane distribution of emissivity and the heating means is opposed to one of the two main surfaces, which has a smaller distribution ratio, thereby realizing uniform and efficient heating/cooling.
Abstract:
A linear motor includes a coil for receiving an electrical current and a first plurality of permanent magnets. The coil and the first plurality of permanent magnets move relative to each other in a direction of relative movement when an electrical current flows through the coil. The permanent magnets are arrayed in the direction of relative movement to form a first array. The direction of polarity of each permanent magnet in the first plurality of permanent magnets is oriented 90.degree. relative to the direction of polarity of an adjacent permanent magnet in the first plurality of permanent magnets. The first plurality of permanent magnets has a main portion and an end portion comprising plural corrective permanent magnets. Each of the plural corrective permanent magnets is smaller than the permanent magnets in the main portion having the same or opposite direction of polarity.

Abstract:
A probe for applying a voltage to lines provided on a substrate comprises (a) a conductive sheet, the conductive sheet including a mesh sheet in which linear members are woven into a mesh and a conductive material which coats the mesh sheet, (b) an elastic member for pressing the conductive sheet against the lines, and (c) a holding member for holding the conductive sheet and the elastic member together. The probe has improved electrical connectivity and durability, and achieves a reduction in size and facilitation of operations of an apparatus for manufacturing an electron source.
Abstract:
In an electron source manufacturing apparatus, the quantity of heat generated from an electron source substrate is measured. A temperature of a support member for the electron source substrate is controlled based on the measured quantity of heat generated. A variation in performances of electron source substrates is suppressed, which increase their life.
Abstract:
A weight supporting apparatus supports the weight of a structure required to have very high surface precision, without affecting the surface precision of the structure. The weight support apparatus includes a driving unit for moving a driven body in the direction of gravity with respect to a base, and a supporting unit for supporting the weight of the driven body at a position after being driven, wherein the driving unit and supporting unit are so arranged that the drive force of the driving unit and the support force of the supporting unit are on the same axis.
Abstract:
A manufacturing method of an image display apparatus, having a vacuum container with getters therein, includes the steps of exhausting an inner gas through an exhaust hole provided in the vacuum container; and activating the getters during the exhausting. In the activating step, the getters are sequentially activated first from a getter positioned in an area having a larger exhaust conductance with respect to the exhaust hole.
