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.

Voltage applying apparatus, and apparatus and method for manufacturing electron source

This invention provides an electron source manufacturing apparatus and manufacturing method which facilitate downsizing and operation and are suitable for mass production. The electron source manufacturing apparatus includes a support which supports a substrate having conductors formed on it and has a means for adjusting the temperature of the substrate, a vessel which has a gas inlet port and gas exhaust port and covers a partial region on the surface of the substrate, an unit for introducing and exhausting gas into and from the vessel, and an unit for applying a voltage to the conductors. The support has a groove.

Electron source manufacturing apparatus

Electroconductive frit includes glass (14) having a low melting point and a filler of fine glass particles (12) coated on the surface with metal(13). The electroconductive frit is used for bonding a spacer to an electron source substrate and a face plate in an image-forming apparatus to ensure mechanical securing strength and electrical connection.

In an optical element, an optically transparent substance is sandwiched between transparent paired plate-shaped elements by utilizing a connection member capable of deforming, and the angle formed by the paired plate-shaped elements is caused to vary by a force applied thereto from the outside, so that a predetermined optical characteristic for the passing light rays is obtained. The connection member is constructed from a high-molecular material capable of molding.

Variable-angle optical device with optically transparent substance

An optical device for stabilizing an image of an objective lens against an unexpected vibration is disclosed. A pair of transparent parallel-plane plates are supported by a support member, an optically transparent material is held in a space defined by the pair of parallel-plane plates by a deformable connecting member, a reinforcement member made of a harder material than that of the support material is provided at a portion of the support member, and a drive force is applied to the pair of parallel-plane plates through the reinforcement member.

There is disclosed an optical device capable of deforming a member connecting a pair of optically transparent parallel-faced flat plates, thus varying the mutual angle of the paired flat plates and obtaining a predetermined optical performance on the passing light beam. The connecting member is formed by connecting plural elastic members so as to form Y-shaped or modified Y-shaped cross section in a number at least equal to zero. The connecting member is formed, in at least a part of the elastic members, by one-layered or plural-layered polymer films.

Optical device and producing method therefor

An angular displacement detecting device which is provided with a tubular casing having a chamber in which a liquid is sealed, a floating body having a magnetic characteristic, the floating body being disposed in the liquid sealed in the chamber and being supported for rotation about a predetermined rotational axis, a magnetism generating member for cooperating with the floating body to constitute a magnetic circuit, and a detector for detecting a relative rotation about the rotational axis between the floating body and the tubular casing. The floating body is formed of either a material in which a magnetic material powder with a particle size of 10 .mu.m or less is dispersedly mixed with a thermoplastic, high polymeric organic material or a material in which a magnetic material powder whose particles are coated with a silane or titanium coupling agent is mixed with a thermoplastic, high polymeric organic material.
