Title: Process to modify work functions using ion implantation
Inventor: MUSKET RONALD G
IPC: H01J9/02
Filed: 1997-06-07
Granted: 2000-08-01
Abstract: The work function of electron emitters can be modified by forming a work function modifying layer at the surface using ion implantation. The process starts with low-energy implantation, in a controlled environment, of chosen elements below the surface of electron emitters. In some cases, the implanted species are deep enough that they do not react with the atmosphere during subsequent low-temperature processing. In these cases, segregation of the implanted species to the emitting surfaces is done using elevated temperature thermal treatment of the emitters in a controlled environment (e. g. vacuum and/or reactive gases). The implanted ions produce a work function modifying layer at the surface, e. g. in the form of thin layers of the implanted species on top of the emitter surfaces, or compounds or alloy layers at the surface of the emitters. Depending on the implanted species, the initial emitter material, and the controlled environment, these layers can either increase or decrease the work function or the emitter.

Granted: 1999-12-21
Abstract: An LED chip is mounted in a horizontal state in such a manner that a PN junction surface is normal to a unit substrate. A side surface of a crystal surface of the LED chip is recessed in such a manner as to have a distance with respect to a surface of the unit substrate, or is wholly covered by an electrically insulating film formed of an ultraviolet curable type resin, so that even when the LED chip is in contact with wiring patterns of the unit substrate, an electric trouble such as an electrical short is not generated. An electrical connection to the LED chip is performed by connecting thick film electrodes provided on both sides in a perpendicular direction to a PN junction surface, and the wiring patterns on the unit substrate to each other through electrically conductive pastes. Since a multiplicity of horizontally mounted LED chips can be mounted on the unit substrate without necessity of positioning at a high accuracy; an image display unit performing a matrix display can be easily manufactured.

Patent TW-391021-B (TW)
Title: Variable capacitor
Inventor: SHIBATA YASUNOBU
IPC: H01G5/06
Filed: 1998-09-02
Granted: 2000-05-21
Abstract: A variable capacitor has a stator, a rotor, and cover. The stator includes a stator electrode and a stator terminal connected electrically to the stator electrode. The rotor includes a rotor electrode facing the stator electrode with a dielectric disposed therebetween. The cover is shaped so as to accommodate and hold the rotor so that it can be rotated relative to the stator. An adjustment hole is formed in the cover so as to permit insertion of a tool for rotating the rotor. A spring-action portion is formed around the adjustment hole to thereby press the rotor against the stator. The stator terminal is formed so as not to extend onto a stator surface facing an edge portion of the cover, thereby maintaining a relatively long distance between the stator terminal and the edge portion of the cover and the between the stator terminal and the rotor. Thus, when the size or thickness of the variable capacitor is reduced, the problem of short circuiting or poor dielectric strength, which would otherwise tend to occur when the edge portion of the cover and the rotor are located in the proximity of the stator or when the cover or the rotor is dislocated during rotation of the rotor, can be effectively prevented. Also, rotor deformation can be prevented which would otherwise result from a pressing force applied to the rotor by the spring-action portion.
