Title: Low voltage ballast circuit for a high brightness discharge light source
Inventor: ALLISON JOSEPH M
IPC: H02M3/155
Filed: 1993-02-11
Abstract: LD 10,444 LOW VOLTAGE BALLAST CIRCUIT FOR A HIGH    BRIGHTNESS DISCHARGE LIGHT SOURCE               ABSTRACT OF THE INVENTION A low voltage DC input ballast circuit for a discharge lamp particularly suitable for a central lighting system includes an input filter stage which feeds into a first boost converter circuit controlled by way of a pulse width modulator device. The first boost converter provides warm-up and steady state run signals to the lamp in a voltage fed manner over a coupling circuit using components which are reduced in size relative to conventional discharge ballast circuits.   Control circuitry provides various monitoring function , an example of which is that, in the event of a low input voltage, the lamp will operate in a dimmed or faded manner rather than maintain lumen output by drawing additional current.   A second boost converter circuit is associated with a starter circuit arrangement and operates such that starting pulses can be generated and repeated if necessary in a very rapid manner.

Title: Improved solid state microanemometer
Inventor: HENDERSON H THURMAN
IPC: G01P5/12
Filed: 1991-12-12
Abstract: A solid state microanemometer (10) is micromachined from a crystal to a shape with four thick external sides (14, 15, 16, 17) that define an outer rectangle, four thin sections (24, 25, 26, 27) that define an inner rectangle and four diagonally directed branches (18, 19, 20, 21) interconnecting the corners of the outer rectangle to the inner rectangle. Four semiconductor resistors (34, 35, 36, 37) located on the four inner sections (24, 25, 26, 27) form a sensing bridge. Each external side (14, 15, 16, 17) has a pair of electrical contacts (43 and 44, 51 and 52, 59 and 60, 67 and 68) that are electrically interconnected, via conductive leads (39 and 40, 47 and 48, 55 and 56, 63 and 64) that extend along the diagonal branches and partially along the inner sections, to one of the semiconductor resistors (34, 35, 36, 37). The physically connected semiconductor resistors (34, 35, 36, 37) and external sides (14, 15, 16, 17) form a rugged solid state device (10), while thermal and electrical isolation of the resistors (34, 35, 36, 37) from each other permits higher operating temperatures and improved fluid flow sensing capability.

Title: Lithographic printing plates
Inventor: MITCHELL JAMES E
IPC: G03F7/027
Filed: 1992-03-24
Abstract: Negative-working lithographic printing plates comprise a radiation-sensitive composition having incorporated therein a photocrosslinkable polymer, containing the photosensitive group (I) as an integral part of the polymer backbone, and a print-out composition which produces an optical density difference upon exposure to activating radiation and thereby enables the exposed image on the printing plate to be seen before the plate is processed. The print-out composition comprises a leuco form of a dye having one or more removable hydrogen atoms, the removal of which forms a compound colored differently from the leuco form; a photo-oxidant which has a photoscissionable nitrogen-oxygen bond, the photo-oxidant serving to convert the leuco dye to the differently colored form when the composition is exposed to activating radiation; and a heteroaromatic amine N-oxide which functions to improve the photo-efficiency of the print-out composition and thereby increase the print-out density.

Patent CA-2105855-A1 (CA)
Inventor: KROM THOMAS J
IPC: H01R11/09
Filed: 1992-07-01
Abstract: A clamping assembly (10) which provides a un-iform pressure simultaneous-ly at two spaced apart points. The assembly inclues a por-tion of a support member (14) which has two parallel sides and a passage connect-ing the two parallel sides. A tubular shaped sleeve (22) is received within the passage and includes short tabs ex-tending slightly past the sur-face of the two parallel sides of the support member. A U-shaped anti-turn bracket (30) is slidably received around the support member and in-cludes slots that coincide with the passage in the sup-port member. The tubular sleeve has a non-circular in-side cross section. A double-ended bolt (26) having a first and second threaded end and an intermediate non-circular portion complementary to the non-circular cross section of the sleeve is slidably received within the sleeve. The bolt is permitted to move linearly but not permitted to rotate within the sleeve. Threaded nuts (138, 142) are placed on each of the first and second threaded end. A uniform torque at both of the first and second ends can be obtained by tightening only one of the nuts without requiring the other nut to be held or tightened. This is accomplished by the ability of the bolt to slide linearly within the sleeve while being prevented from rotating.

Inventor: KOJIMA TATSURU
IPC: H03L7/10
Filed: 1994-03-29
Abstract: A frequency synthesizer, which realizes speed-up of channel switching between channels having separated frequencies,  has an EEPROM  which  stores  the  phase  difference  between  a  first frequency divider  and a  second  frequency divider producing outputs corresponding to the frequencies of the channels to be switched.   A delay circuit delays the output of the second frequency phase divider by an amount corresponding to an amount of the phase difference stored in the EEPROM.   A controller supplies the outputs of the second frequency divider and the delay circuit to a phase detector.  Further, the controller stops a PLL operation and restarts it in synchronism with a leading edge of, preferably, a second period of the output signal of the reference oscillator to which the preset phase difference is given.
