Patent CA-2539255-A1 (CA)
Inventor: UCHIDA ISAMU
IPC: H01M8/02
Filed: 2005-02-25
Abstract: A membrane electrode assembly where electrolytic catalyst is stuck selectively to the surface of a solid state polymer electrolytic membrane, its production method, and a solid state polymer electrolytic fuel cell comprising the membrane electrode assembly. Central technology of the fuel cell is a thin film device referred to as a membrane electrode assembly (MEA) where a solid state polymer electrolytic membrane (2) and an electrode are stuck together, and that device leads the practical use of a vehicle-mounted fuel cell or a home-use fuel cell. The current MEA poses such a problem that electrode catalyst is applied to the entire surface of the electrolytic membrane (2) having a structure of being-phase separated into an ion conduction domain (3) and a ion nonconduction domain (4),but only the electrode catalyst touching the ion conduction domain participates in electrode reaction, thus wasting a large quantity of electrode catalyst that does not participate in electrode reaction. That problem is solved by spraying liquid containing an electrode catalyst and a solvent to the surface of the electrolytic membrane (2) by an electrostatic spraying method, thereby deposit the electrode catalyst (5) selectively to that surface part of the electrolytic membrane (2) corresponding to the ion conduction domain (3).

Title: Lamp assembly having variable focus and directionality
Inventor: BYNUM STEPHEN A
IPC: B60Q3/00
Filed: 2005-02-11
Abstract: A lighting assembly (10) is adjustable between flood and spot lighting conditions for selectively illuminating an interior passenger compartment in a motor vehicle. The assembly (10) includes a housing (16) which clamps to a supporting member, such as a headliner (12), via a sleeve (18) interacting with a rotary cam lock (22). An LED light source (26) is orbitally supported within the housing (16) for projecting light in a directionally adjustable manner. A lens (50) is disposed in the light path (28) and is moveable between an extended spot position for task lighting and a retracted flood position for general illumination within the interior compartment. A switch (74) is responsive to movement of the lens (50) into its spot position for automatically energizing the LED (30). The switch (74) opens, thus de-energizing the LED (30) when the lens (50) is returned to its flood condition.  A lighting control circuit (78, 78') is responsive to an override signal, such as from a door switch (80, 80'), for independently activating the light source (26) when the lens (50) is in its flood position. The light source (26) is supported for orbital movement within the housing (16) by a gimbal mechanism which includes an inner gimbal (38) carried in a cross (40). Pintals (42, 44) establish intersecting perpendicular axis (A, B) to accomplish the orbital movement. A latch mechanism (64) cooperates with leaf springs (62) by controlling movement of the lens (50) between its flood and spot conditions by a repeated push impulse applied by the finger of an operator. The switch (74) is incorporated into the leaf springs (62).
