Patent number: 5504385Abstract: In accordance with the invention, a field emission device is made by disposing emitter material on an insulating substrate, applying a sacrificial film to the emitter material and forming over the sacrificial layer a conductive gate layer having a random distribution of apertures therein. In the preferred process, the gate is formed by applying masking particles to the sacrificial film, applying a conductive film over the masking particles and the sacrificial film and then removing the masking particles to reveal a random distribution of apertures. The sacrificial film is then removed. The apertures then extend to the emitter material. In a preferred embodiment, the sacrificial film contains dielectric spacer particles which remain after the film is removed to separate the emitter from the gate. The result is a novel and economical field emission device having numerous randomly distributed emission apertures which can be used to make low cost flat panel displays.Type: GrantFiled: August 31, 1994Date of Patent: April 2, 1996Assignee: AT&T Corp.Inventors: Sungho Jin, Gregory P.

Patent number: 5502352Abstract: According to the present invention, a spark plug for an internal combustion engine includes a center electrode, a ground electrode so as to form a spark gap with the center electrode, and a tip electrode composed of a material having a superior consumable resistance as compared to the center electrode and disposed on an end face of the center electrode so as to form a spark gap with the ground electrode. An axial length of the discharge portion of the ground electrode where spark discharge occurs is substantially larger than an axial length of the tip electrode where spark discharge occurs. When used for an internal combustion engine, a spark discharge is mainly generated between the peripheral surface of the center electrode and the ground electrode during early operation. Consequently, as the center electrode has been consumed, the spark discharge is mainly generated between the tip electrode and the ground electrode.Type: GrantFiled: August 16, 1994Date of Patent: March 26, 1996Assignee: Nippondenso Co., Ltd.Inventors: Akio Katoh, Kozo Takamura

Patent number: 5502436Abstract: A system of domestic audio-visual apparatuses (10-18) are connected on a one-to-one basis (20-26) for the exchange of video and audio signals. The apparatuses are also connected to a serial data bus (28,D2B) which allows distributed control messages to be sent and received by the apparatuses (addressable as `devices`) and elements of the apparatuses (subdevices). No apparatus has knowledge of the complete system of connections (20-26). An autonomous process (100, 102, 104, 110') can be initiated whereby a signal path from a source subdevice (64) to a destination subdevice (62) is identified step by step using the local knowledge of each apparatus. The speed of this process can be improved by initiating (101) a concurrent second autonomous process (106') whereby a signal path is identified from a third subdevice (42) to the destination subdevice.Type: GrantFiled: October 11, 1994Date of Patent: March 26, 1996Assignee: D2B Systems Company LimitedInventor: Bernard van Steenbrugge
