Title: Boiler control
Inventor: KINGE RICHARD ARTHUR GEORGE
IPC: F23N5/24
Filed: 1989-10-31
Abstract: A gas-fired heating boiler comprises a gas burner 1, a heat exchanger 6 healed by the gas burner and through which is passed a fluid to be heated, a fan 4 for providing combustion air to the burner 1, and a control circuit for controlling the speed of the fan 4 and gas flow to the burner 1 in dependence upon the temperature of the heated fluid, the flow of air from the fan 4 and the pressure of gas supplied to said burner.

Title: Method and apparatus for spatial anti-aliased depth cueing
Inventor: PRIEM CURTIS
IPC: G06T15/50
Filed: 1990-03-02
Abstract: To enable a computer graphics system to produce lines of varying thickness, thereby adding depth cues, the lines are drawn as quadrilaterals from vertices information. Each end A or B of a line 82 to be drawn has a depth value assigned and this produces a corresponding line width value. This in turn produces a pair of quadrilateral vertices (84, 85 and 86, 87) whereby the complete line can be drawn as a quadrilateral. Antialiasing techniques are used for edges 90. <IMAGE>

Title: Recording/reproducing apparatus
Inventor: ARUGA TOMOE
IPC: G11B33/02
Filed: 1990-04-19
Abstract: A recording/reproducing apparatus used, for example, for a computer, and particularly an apparatus for recording desired data on a recording medium such as a floppy disc and for reproducing data. The recording/reproducing apparatus is realized in a small size with reduced thickness to meet modern computers of small sizes. In order to reduce the thickness, furthermore, a rare earth magnet and a Nd-Fe-B magnet that are small and produce strong magnetic force are used as rotor magnets for a motor for driving the disc and for a motor for driving a carriage. Furthermore, the motor for driving the disc, the carriage or a guide shaft of the carriage and a circuit board are so arranged that they will not be overlapped on a plane. The recording/reproducing apparatus with a reduced thickness requires a small space for arrangement in a computer to meet the tendency toward designing computers in small sizes. Further, the recording/reproducing apparatus of a small size can be arranged in a plural number in the existing space for arrangement.

Title: Method and apparatus for stretching web of plastic sheet into arcuate form
Inventor: MATSUDA NAOHIKO
IPC: B29C35/00
Filed: 1990-06-29
Abstract: The invention relates to stretching of a continuous web (10) of a thermoplastic sheet, such as polyvinyl butyral sheet having straight longitudinal edges into an arcuate form to use it as an interlayer of curved and laminated windshields of vehicles. Usually the web (10) has a colored band (12) to serve as a glare shield band along its one longitudinal edge (10a). First the web travels vertically downward and is heated from both sides by a vertical heater (22) to produce a gradient of temperature across the width of the web such that the temperature at the web edge (10b) remote from the colored band becomes higher than the temperature at the opposite edge (10a). Under longitudinal tension the heated web is passed around a first heated tapered roll (30) and then around a second heated tapered roll (32) having a higher temperature. Over these tapered rolls (30, 32) the web edge (10b) remote from the colored band is located relatively near the large diameter end of each tapered roll. The web stretched by the two heated rolls is successively passed over a plurality of cooled tapered rolls (34, 36). <IMAGE>

Title: Horizontal form-fill-seal machine with inert gas injection and heat shrinking
Inventor: SUGA TADORU
IPC: B65B51/30
Filed: 1991-10-21
Abstract: A horizontal form-fill-seal machine has means 19 for evacuating the tube 18 with the articles 10 in it, and means 24 for injecting an inert gas into the evacuated enclosure. The evacuation means may be a flat rectangular nozzle 19 (fig 3) with suction holes 20 down each side. The gas injection means 24 projects from the front of the evacuation means. Heat-sealing bars 25, 26 are carried on guide bars (45, 46, fig 6) which are in turn slidably mounted on guide bars (30, fig 5). The heat sealing bars move in the same direction and at the same-speed as the film between two positions, and then return to their original position. This motion can be achieved using a cam mechanism. A plate (91, fig 9) presses excess gas out of each package before the sealing takes place. The plate may be moved by an air cylinder (89, fig 9) and may have a soft porous material on its underside (99, fig 9). After sealing the wrapped package 13 is passed through a heat-shrinking device 104 to tauten the film over the article (fig 10). <IMAGE>

Title: Bicmos device and manufacturing method therfor
Inventor: KIM MYUNG-SUNG
IPC: H01L21/28
Filed: 1992-05-15
Abstract: A BICMOS device and manufacturing method therefor are disclosed wherein the gates 47, 45 of PMOS and NMOS transistors PM, NM are formed from a first polysilicon layer 33 free from impurity implantation and a second polysilicon layer 39, formed on the first polysilicon layer and being impurity implanted. The impurities implanted in the second polysilicon layer 39 are prevented from diffusing into the channel region and variation of the voltage characteristic of the device is thereby prevented. Furthermore, the emitter regions 81, 88 of the PNP and NPN bipolar transistors FB, NB are self-aligned within a small chip area. Consequently, the performance of the BICMOS device is improved, due to the stable threshold voltage characteristic of the PMOS and NMOS transistors, and high density is achieved together with improved speed of operation. The gates of the MOS transistors also comprise a silicide layer 41 to increase conductivity. <IMAGE>
