Abstract: Multiple concentric, triangular cross-sectioned fluorescent lamp tubes, located substantially in the same plane with respect to each other, are utilized in appropriate assemblies for: 1) a direct screw-in replacement for reflective incandescent lamps and; 2) recessed ceiling fixtures that are typically hardwired. The inherent triangular geometries of the concentric, substantially same plane lamps create mutually benefiting reflecting surfaces to maximize the net light output. The triangular geometry enables light from two sides of the fluorescent tubing to be efficiently cast if desired (or muted by absorbent housing wall if desired). The remaining side, or base, of each triangular tube produces light that is redirected by opposing, intersecting, coaxial, conical reflectors arranged to direct the light through the unobstructed center of the concentric tubing arrangement. A transparent collimating structure adjacent to the triangular tub bases is used to enhance control of the light emanating from the base.

Abstract: A method for battery saving in a selective call receiver (20) that comprises a baud rate detector (210) and a receiver circuit (202) for receiving and demodulating a selective call signal. The selective call signal comprises a preamble (102) and a plurality of data batches. Each of the plurality of data batches further comprises a synchronization codeword (104) and a plurality of assigned data frames (106). The method (30) begins when a predetermined baud rate is detected in each of the plurality of assigned data frames (106) in one of the plurality of data batches. Upon detecting the predetermined baud rate, the selective call receiver (20) inactivates the receiver circuit (202) for the duration of the synchronization codeword (104) in a subsequent one of the plurality of data batches. Otherwise, the receiver circuit (202) remains activated during the synchronization codeword (104) of the subsequent one of the plurality of data batches.

Abstract: A matrix wiring substrate is provided which can perform an electrostatic countermeasure until drive circuits are connected to a matrix wiring substrate, whereby the circuit wiring can be inspected at an earlier stage. The matrix wiring substrate, where circuit wiring is formed over a substrate, includes a guard ring formed around the circuit wiring and connected to the circuit wiring, and separable portions arranged between the circuit wiring and the guard ring for controlling the conduction between the circuit wiring and the guard ring. Since the circuit wiring is conducted with the guard ring by effecting externally the separable portion, lines of the circuit wiring are short-circuited electrically. No potential difference between the wires causes any electric discharge, thus resulting in increased manufacturing yield.

Abstract: To provide a strain relief in a base for an electric lamp, adapted for coction to an external electrical energy source by at least one connection cable (6a, 6b) extending through and into the base, the base (2) is formed with a strain relief arrangement which includes a resilient sleeve (11) having an inner wall surrounding the at least one connection cable and, within the base bottom portion (9, 9'), a sleeve reception structure (9a) positioned inwardly of the bottom of the base, which includes a sleeve reception bore (10a, 10b) receiving and surrounding the resilient sleeve (11a, 11b) and exerting circumferentially uniformly, radially inwardly directed forces on the resilient sleeve. This decreases the diameter of the sleeve so that the inner wall thereof engages, clamps and squeezes the deformable insulation of the at least one connection cable and, also, can interengage or interlock therewith. The bottom portion (9) and the top portion (7) of the base are snapped together.

Abstract: In a radio paging receiver for receiving a pager signal comprising a succession of frames each of which consists of a first through n-th group of signals, a first clock generating unit generates a first clock signal having a first clock rate. A synchronization clock generating unit generates a synchronization clock signal which is synchronized with digital word data derived from a receiving section and which has a synchronization clock rate equal to the first clock rate. A selecting circuit selects one of the first clock signals and the synchronization clock signal as a selected clock signal. A counter carries out a counting operation by the use of the selected clock signal and produces a counted signal. Responsive to the counted signal, a control circuit produces a control signal to make a battery saving switch have an "on" state and to make the synchronization clock generating unit have an active state.

Abstract: A method in a communications receiver (20) for handling a selective call message comprises the steps of measuring a parameter of the selective call message (104, 116) and selecting whether to provide the selective call message to a display (118) or a communications port (106) in response to measuring the parameter of the selective call message (104, 116). The communications receiver (20) can function as either a pager or a radio frequency (RF) modem. A controller (66) determines the parameters of the message and operates the communications receiver (20) as a pager or as an RF modem in response to the parameters measured.

The spark plugs embodying the present invention are particularly useful in continuous cycle or heavy duty cycle engines that have heretofore been the subject of severe electrode erosion.

Abstract: A photomultiplier uses an avalanche photodiode as a position-sensitive anode. The envelope of the photomultiplier has a flat input end. Electrically conductive regions mounted to the input end are configured to produce at the input end a potential distribution characteristic of a photomultiplier with a spherical-type input end as measured in a transverse plane immediately adjacent the spherical-type input end. A photocathode is located inside the photomultiplier and is electrically connected to the electrically conductivew regions. Advantageously, the envelope has flat sides and a square cross-section; in this instance, conductors are run along the sides to produce within the envelope a potential distribution characteristic of a photomultiplier which is cylindrical in cross-section, as measured at flat surfaces having the same shape as the envelope.

The screen panel, front panel and funnel portion are combined through frit glasses, and a phosphor screen is formed on the inner surface of the screen panel. An electron gun is disposed within the neck portion, so that an electron beam generated from the electron gun collides with molecules within the flat glass tube to generate negative ions. The negative ions are accelerated and irradiated at the center portion on the skirt portion provided at the front end of the screen panel, whereby the phosphor screen is prevented from being burned by the ions and degradation of the frit glass due to impact of the negative ions is prevented.

Abstract: To prevent corrosion of molybdenum connecting pins or wires extending from elt-sealed ends of high-power lamps, the region immediately adjacent the exit points from the melt-sealed end are cooled by a cooling gas, for example air or an inert gas such as nitrogen. The cooling gas is applied by cooling ducts which are made of metal and, simultaneously, provide for electrical connection of electrical energy to the connecting leads. Cooling gas can be introduced either through terminal pins or rods into the tubular elements, or the tubular elements can be connected, as usual, to the part-solid terminal pins or rods and additional gas connections are passed through the base through the tubular elements to supply cooling gas.

Abstract: A paging receiver of the present invention includes a decoder for processing a paging number and a message signal of a transmitted radio signal and receives the radio signal selectively by comparing the paging number with a predetermined paging number of the receiver. A timer stamps the message signal with current time when the paging number coincides with the predetermined paging number of the receiver. A memory stores message signals already received and stamped with time information. The message signal stamped with current time is compared with the message signals stamped with received time stored in the memory and, when contents of these message signals are coincident and a difference in time between these message signals is within a predetermined time, the message signal is deemed as an urgent message and an urgent report is performed.

Abstract: A communication receiver (106) receives an address code word (1800) of a transmitted message, the message comprising the address code word (1800) and an associated data portion (1610), the address code word comprising an address portion (1802,1804). The communication receiver (106) corrects (2104) up to a predetermined number of bit errors in the received address code word (1800). The communication receiver (106) can conserve power following a failed correction of the address code word (1800). Alternatively, the communication receiver (106) compares (2108,2111) the address portion (1802,1804) of the corrected address code word (1800) to at least one predetermined subscription address (1704,1706). The communication receiver (106) can conserve power following a determination of no match (2110,2114,2308) between the address portion (1802,1804) of the corrected address code word (1800) and the at least one predetermined subscription address (1704,1706).

Abstract: An imaging tube having a fiber optic plate (FOP) as an output faceplate. On one surface of the FOP within an evacuated envelope is deposited a first transparent conductive layer. On the first transparent conductive layer is deposited a fluorescent layer. On the fluorescent layer is deposited a metal-back electrode. On the other surface of the FOP outside the evacuated envelope is deposited a second transparent conductive layer. The first transparent conductive layer and the metal-back electrode are electrically connected so that an electrical field is not developed across the fluorescent layer when the metal-back electrode is applied with a high positive voltage and the second transparent conductive layer is grounded. Therefore, even if leakage currents flow through the FOP, electric charges impinging upon the first transparent conductive layer will not cause the fluorescent layer to generate noise spots.
