Patent GB-2357398-A (GB)
Title: Soft handover
Inventor: LUNDQVIST ANDERS
IPC: H04B7/02
Filed: 1999-12-16
Abstract: A cellular communications network using macrodiversity, for example a CDMA network, allows a network operator to influence movements of a mobile station within the radio environment. Cells are considered in groups. When a handover is contemplated, the system takes into account the groups which include the cells to which radio links are already established and the group which includes the cell to which the establishment of a new radio link is contemplated. A candidate cell, which is in a different group from all existing cells to which radio links are already established, must meet a higher quality threshold than if it is in a group to which a radio link is already established, before a link to it is established.

Title: Chromatic dispersion measurement system
Inventor: FORTENBERRY RANCE M
IPC: G01J3/46
Filed: 1999-12-20
Abstract: The chromatic dispersion of an optical system (22) having physically separated access points is measured, wherein a modulation signal (23) at a local access point (LAP) of the optical system (11) and a reference signal at a remote access point (RAP) of the optical system are generated and the signals are synchronised via timing signals (19) derived from global positioning satellites (GPS). The signal (23) modulates optical test signals (25) having predetermined optical wavelengths and the modulated optical test signals (27) are applied to the local access point of the optical system (22) and transmitted to the remote access point where the signals are demodulated. The time delay of the demodulated signal relative to the reference signal is measured at the remote access point by a phase comparison or alternatively by measuring the relative time delay directly. The relative time delay through the optical system (22) as a function of optical wavelength provides a measure of chromatic dispersion of the optical system between the local and remote access points.

Title: Thermal head
Inventor: ANNO GOUSUKE
IPC: B41J2/355
Filed: 1980-01-31
Abstract: PURPOSE: To reduce the number of leading wires and to enable a high-speed recording by the use of a simple circuit constitution, by a method wherein shift registors having the number of bits equivalent to that of heating resistors and the number of driving circuits equal to that of the shift registors are mounted on a substrate of a thermal head.  
     CONSTITUTION: With a picture signal equivalent to a line inputted to a terminal 9, shift registors 8 transfer the signal in turn to the right according to clock signal for storing. After the picture signal is stored, it is transferred to a latch circut 14, and selectively turns on a driven circuit 4 during only a period during which an output approval signal from a terminal 15 is inputted. This performs a simultaneous recording equivalent to a line when a heating resistor 1 is selectively energized. A large number of current may flow to buses L 1  and L 2  for current feed to the heating resistor 1 at that time, and thereby utilization of a metal plate 31 for radiation for a head and a metal cap 33 as the buses L 1  and L 2  permits prevention of voltage drop occurring at a time when a large amount of current passes.

Abstract: PURPOSE: To mix ejection fuel and air evenly and improve distribution performance by providing a mixing chamber, between the position where fuel supply valve opens to the suction path and the position where many suction branch pipes gather together, whose cross section area is larger than the sum of the cross section areas of these pipe paths.  
     CONSTITUTION: At the time of the operation of engine 1, signals, Tw, etc., showing the amount of air flowing in air passage 9, or the condition of the engine are taken into control unit 11, and the signal corresponding to the amount of fuel to be supplied to engine 1 is given to ejection valve 10. Fuel is ejected from ejection valve 10 corresponding to the drive signal from unit 11. In this case, in the condition where the amount of suction air is small with respect to the degrees of opening of throttle valves 6a, 6b, the speed of air flow is small and the atomization of fuel is unstaisfactory. For this reason, mixing chamber 2, whose passage capacity is locally enlarged, is provided on the lower stream side of throttle chamber 5 in suction multi-branch pipe 3. By this, the speed of suction air flow is rapidly decreased and fuel drops are atmomized, and thereby fuel and air are mixed evenly.

Title: Rotary mirror
Inventor: HONMA YOSHIFUMI
IPC: G02B26/12
Filed: 1992-01-24
Abstract: PURPOSE:To reduce the nonuniformity of scanning caused by the falling-down of planes and the generation of vibrations or noise caused by the imbalanced shape or air pressure by providing a concentric arc-shaped plane between two reflecting mirror planes faced each other with a rotating core as a center. CONSTITUTION:A rotary mirror 100 forms only two reflecting mirror planes 101 and 102 by cutting two faced positions into planes with the rotating core as the center on the outer peripheral face of an aluminium base equipped with the cylindrical outer peripheral face. Therefore, even assuming that there is plane falling-down error between the first and second planes of the two reflecting mirror planes 101 and 102, the pitch of black or white is always fixed and image nonuniformity is not generated since the back and black or the white and white are printed by deflection depending on the same plane totally. Since a surface connecting the two reflecting mirror planes 101 and 102 of the rotary mirror 100 is concentrically arc-shaped, the influence of the imbalanced shape or the air pressure and the generation of turbulence are reduced, and the adverse influence generated in the case of high-speed rotation can be reduced as well.
