The present invention relates to imidizo derivatives containing a plurality of imidizo moieties linked by aryl or heteroaryl groups. The resultant imidizo derivates may advantageously be used in organic electronic devices, such as multi-layer organic electroluminescent devices or organic photovoltaic devices, and in chemical sensing applications as a host material.

Imidizo derivatives

Compounds containing bibenzochalcogenophene structures are provided in which the chalcogenide is sulfur, selenium, or tellurium. The compounds are characterized by planarity, rigid conjugation structure and high charge mobility making them useful as organic semiconductor in optical devices, electronic devices and integrated devices like organic field effect transistors (OFET) for thin film transistor liquid crystal display (LCD), electrophoretic display such as electronic paper, organic light emitting diode (OLED) for flat panel displays, organic radio frequency identification (ORFID) tags, organic photovoltaic (OPV), sensor devices, and analog and digital electronics.

Organic electroluminescent devices

A method for forming a field emission flat panel display includes deposit a conductive patterned layer on a substrate, depositing an emitter material over the patterned layer, patterning the emitter material to provide a series of mask caps, etching the emitter material to provide arrays of emitter peaks with the mask caps thereon, depositing a dielective layer on the patterned layer and on the mask caps, depositing a conductive gate layer on the dielectric layer, depositing a high-resistivity dielectric layer on the gate layer, depositing a low-resistivity dielectric layer on the high-resistivity dielectric layer, and etching away portions of the dielectric layer, gate layer, high-resistivity dielectric layer and low-resistivity dielectric layer to expose the mask caps, and removing the mask caps to expose the emitter peaks to provide an emitter cathode panel, providing a transparent panel having a conductive coating thereon, and depositing a layer of thin film phosphors on the conductive coating to provide an anode screen, and attaching the anode screen to the cathode panel.

Field emission flat panel display with improved spacer architecture

A luminescent composition which is a uniform admixture of a least one phosphor having a particle size of about 'one-half' micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor. Luminous devices are formed by disposing this composition on a substantially transparent substrate. The use of particulate phosphors in an encapsulating medium protects the phosphor and provides dielectric strength or conduction as required. Improved luminous devices for displays and lighting are provided such as those finding use as flat panel displays and for backlights for liquid crystal flat panel displays.

A luminescent composition which is a uniform admixture of a least one phosphor having a particle size of about ten micrometers or less and at least one sol gel compound in an amount sufficient to substantially encapsulate the phosphor. Luminous devices are formed by disposing this composition on a substantially transparent substrate. The use of particulate phosphors in an encapsulating medium protects the phosphor and provides dielectric strength or conduction as required. Improved luminous devices for displays and lighting are provided such as those finding use as flat panel displays and for backlights for liquid crystal flat panel displays.

Luminescent device for displays and lighting

In the faceplate of a cathode ray tube or in an FED the amount of light emanating from the phosphor that reaches a viewer is increased by the use of internal and external antireflection layers and concavities between layers on the side of the viewer with respect to the phosphor layer.

A portable door lock and combined smoke and intrusion alarm has an upper forked end engageable with the door handle, a shaft extending in an adjustable length tube and terminating in a non-skid rubber end adapted to engage the floor or carpet. The upper end of the shaft is further retained in its mounted position by a retaining ring or cord. It has its lower end lying in a plane substantially aligned with the longitudinal axis of the shaft. A dual function alarm device is slidably mounted on the shaft and includes an actuator for it with a switch contact normally abutting or close to abutment with the surface of the door at a point below the door handle. Responsive to inward movement and pressure on the door the alarm will be actuated. At the same time, the locking action of the shaft and the upper forked end will divert the opening inward forces into forces directed against the floor so that the door cannot be opened. The alarm device is also actuable by an electrically controlled smoke alarm mounted adjacent to it.

Door locking alarm device

A combination door lock and alarm has an upper end clip engageable with the door handle, a shaft extending in an adjustable length tube and terminating in a non-skid rubber end adapted to engage the floor or carpet. The clip at the upper end of the shaft is angularly mounted and has its lower end lying in a plane substantially aligned with the longitudinal axis of the shaft. An alarm device is also mounted on the shaft and includes an actuator for it with a switch contact normally abutting or close to abutment with the surface of the door at a point below the door handle. Responsive to inward movement and pressure on the door the alarm will be actuated. At the same time, the locking action of the shaft and clip will divert the opening inward forces into forces directed against the floor so that the door cannot be opened.

A heater usable for indoor and outdoor use including a body having an upper and a lower portion. The two portions are separated by a grate adapted to support a solid fuel within the upper portion. The lower portion is operable to receive a receptacle for a lighted semi-solid fuel. The heater can be used in two modes, in a high heat output mode in which the solid fuel is first lit by the semi-solid fuel that is then removed or in a lower heat output mode in which the upper solid fuel is dispensed with and the heat is given off by the lower portion semi-solid fuel receptacle only. The upper portion of the heater is selectively closed or opened by a lid to allow heating operation or to provide damping operation when the lid is in its lowered position.

Portable heater

A wall comprising concrete blocks each having a longitudinally extending, wedge-shaped groove in one side thereof, the groove communicating with a pair of bores that extend through the block. The block is molded in a hollow shell or frame open at its top and bottom, the frame removably mounting a support from which depends a pair of cores by means of which the block bores are formed. Associated with the frame is a compactor and ejector member having at its lower end a base adapted to be accommodated snugly within the frame and having on its lower surface elongate, wedge-shaped grooving means that forms the groove in the block. The grooving means is longitudinally slotted to accommodate the core support and the grooving means and the base also are bored to accommodate the cores.
