Title: Engine exhaust manifold system
Inventor: MA THOMAS TSOI-HEI
IPC: F02M25/07
Filed: 1994-12-02
Abstract: A manifold 24 has branches 22 leading from individual exhaust ports 20 engine to a downpipe 26 and a manifold 34 has branches 32 interconnecting the exhaust ports. The cross-sectional area of each branch 32 facing the exhaust flow from the associated exhaust valve is no less than 25% of the total port area and the branches of both manifolds 24, 34 terminate within the ports 20 in close proximity to the exhaust valves 18. In this way, a large proportion of the exhaust flow discharged from the exhaust valve of one cylinder is captured by the associated branch 32 of the manifold 34 and distributed by this manifold to the exhaust ports 20 of adjacent cylinders where the exhaust valves 18 are closed and leave the exhaust ports of the adjacent cylinders through the associated branches 22 of the manifold 24, scouring the closed ends of the exhaust ports in the process. A flat partition wall (30, Fig. 2) may divide each exhaust port 20 to direct exhaust flow to the manifolds 24, 34. A valve 52 controls the proportion of gases recirculated through the manifold 34 and may form the waste gate of a turbocharger 28. An exhaust gas oxygen sensor may be located in the manifold 34. <IMAGE>

Title: Vehicle:powered sliding door operator and latch
Inventor: WATANABE MITSUHIRO
IPC: E05F15/632
Filed: 1997-01-17
Abstract: A vehicle sliding door is closed by a motor-driven cable drum and cable until a latch engages a striker in a half-latch position, and a ratchet first engages the latch. The latch is then pivoted by motor 13 to a door-closed, full-latch position via cable 6, the ratchet engaging a second latch part. Motor 13 rotates gear 18 and cable lever 22 about shaft 20 to pull cable 6. If a hand is trapped by the door during operation of motor 13, manual operation of door lever 42 releases the ratchet and pivots safety lever 35 so that its surface 39 engages roller 41 on rotating lever 23 connecting gear 18 and cable lever 22. Lever 23 is slid axially so that its roller 26 disengages from a gear slot, and the drive to the latch is disconnected. At the same time, sensor 64 detects operation of safety lever 35 and signals the cable drum motor to open the door. Opening of the obstructed door can be automatic when ammeter 87 detects abnormal current in motor 13 to operate a latch-releasing motor and reverse the cable drum motor.

Filed: 1997-08-11
Abstract: A user performs a manual selection or a gesture selection of a screen object (210, 220, 230) on a screen (150) of an electronic device (100) using a pointing device (190). After a manual selection, such as a single tap, the electronic device (100) automatically presents a temporary directional palette (450) having palette buttons (451, 452, 453, 454, 455) that explicitly state functions of the electronic device (100) Each palette button has a unique compass direction relative to the original tap area. By making a second tap on a desired palette button, a novice user learns available functions of the electronic device (100) and their corresponding directional gestures. Alternately, the user may perform a gesture selection of both a screen object and a function, such as making a double tap or drawing a line in the appropriate direction, before the directional palette appears on the screen (150).

Title: A purity adjustment device for a CRT display
Inventor: PARK KWANG HO
IPC: H01J29/00
Filed: 1997-09-12
Abstract: The purity adjustment device automatically compensates for a purity change of a picture displayed on a CRT screen due to a change of the Earth's magnetic field, caused by a change of location for example. The picture adjustment device includes an initial value determining section 2 for determining a first voltage corresponding to the geomagnetic field of a specified place where the purity of a picture displayed on the CRT is set at white. A detecting coil 3 detects the Earth's magnetic field at the present location of the CRT and produces a second voltage corresponding to the detected magnetic field. The first and second voltages are combined and input to a differential amplifier 4 with a reference voltage set by the variable resistor VR. An amplifying section 5 produces a purity compensation voltage for a purity correction coil 6.

Title: Air-fuel ratio control in engine with exhaust gas purifier containing NOx absorbent
Inventor: TAKANOHASHI TOSHIKATSU
IPC: F02D41/18
Filed: 1998-03-30
Abstract: The air-fuel ratio of a mixture supplied to an internal combustion engine 1 is controlled by an air-fuel ratio control system 5. This receives inputs from sensors measuring the throttle valve opening 4, the intake pipe pressure 7, the intake air temperature 8, the engine coolant temperature 9, the engine rotational speed 10 and the exhaust gas air-fuel ratio 14, as well as a cylinder discriminating signal 11. An exhaust gas purifying device 16 containing a NOx absorbent receives the exhaust gases. The air-fuel ratio is generally set to a lean setting, but it is periodically enriched, which allows the nitrogen oxides absorbed by the absorbent to be reduced, thus re-generating the absorbent. The degree or duration of this periodic enrichment is set to a larger value as the flow rate or flow velocity of the exhaust gases increases. This flow rate is determined from measurements of the engine load, engine speed or intake pipe pressure. These measurements can also be used to determine the duration of the lean-running periods in between the enrichment periods.
