Patent CA-2220817-A1 (CA)
Inventor: ICHIHARA MASAKI
IPC: H04W48/16
Filed: 1997-11-12
Abstract: In a mobile communication terminal, a switch 10 is initially set to an initial setting mode at time of turning on a power supply.  A reference oscillator control circuit is initialized, and in this state, the output frequency of a reference oscillator is usually greatly shifted.  The base station search is first conducted, and as a result, if the base  station  cannot  be  grasped,  an  offset  signal  is generated by a frequency offset generating circuit 12, to shift the output frequency of a reference oscillator 6 through a reference oscillator control circuit 5.   This operation is repeated until the base station is grasped so that the base station search is continued while the output frequency of the reference oscillator 6 is being shifted.          When a grasp of the base station succeeds, the switch 10 is switched to an AFC side to conduct automatic frequency adjustment.

IPC: C07D277/82
Filed: 1996-05-24
Abstract: Les sels solubles dans l'eau de composés d'hydrazone réagissent rapidement avec des composés d'aniline en présence d'une peroxydase et de peroxyde d'hydrogène, produisant une couleur qui peut être mesurée par spectrophotométrie ou visuellement lorsqu'ils sont incorporés à une solution ou à un dispositif de mesure d'analytes. Ces sels d'hydrazone solubles dans l'eau sont utiles pour dépister le peroxyde d'hydrogène ou un analyte qui réagit en produisant du peroxyde d'hydrogène dans un liquide aqueux. A cet effet, on met physiquement en contact un échantillon liquide avec une composition colorante constituée d'un sel soluble dans l'eau d'un composé d'hydrazone et d'un composé d'aniline substitué ou non, en présence d'une substance à activité peroxydante, afin de produire un pigment coloré, et on détecte ensuite le pigment qui se forme en présence de peroxyde d'hydrogène ou d'un analyte qui réagit en produisant du peroxyde d'hydrogène.

Title: Lighter with looped guard
Inventor: ADAMS PAUL H
IPC: F23Q2/46
Filed: 1996-06-03
Abstract: The lighter (10) of the present invention provides a resiliently deformable guard (60) that covers a portion of the striking wheelassembly (14).

Title: Floating piston, piston-valve engine
Inventor: GRAY CHARLES L JR
IPC: F02B19/08
Filed: 1996-09-27
Abstract: A drive train includes an engine having a power cylinder (12) with a power piston (4). Fuel is fed into a combustion chamber (2) located within the power cylinder at one side of the power piston. Intake and exhaust valves (16, 18), in fluid communication with the combustion chamber serve, respectively, to allow intake of air during an intake stroke of the power piston and exhaust of combustion products during an exhaust stroke of the power piston. A floating piston (5) at least partially closes the combustion chamber opposite the power piston and is mounted for reciprocating motion relative to the combustion chamber. The reciprocating motion of the floating piston includes a pressure relieving stroke in which the floating piston moves away from the combustion chamber responsive to a predetermined pressure being produced within the combustion chamber by combustion, to reduce the peak combustion pressure.
