Abstract: An ion source (6, 7) for producing wide, large area type ion beams with a mass-separation device. Four, five, six or so electrode plates (1, 2, 4, 5) with ion holes (11, 12, 14, 15) at the same positions are installed at the outlet of the ion source. A second or third one of the electrodes (2) has Wien filters at the ion holes. The Wien filter has permanent magnets (40, 41) and electrodes (42, 43) for producing a magnetic field and an electric field perpendicular to the axial direction of the ion holes. Ion beams which have not been accelerated so fast are separated by mass by the Wien filter. Low kinetic energy of ions alleviates the strength of the magnetic field and the electric field. Wide, large area type ion beams without impurities are obtained.

Abstract: An N x N integrated optical interconnection apparatus capable of switching, multiplexing, or demultiplexing a large number of input and output wavelength channels achieves low levels of crosstalk and insertion loss. Two substantially identical N x M star couplers (10,12) are connected by an optical diffraction grating comprising M unequal length waveguides spaced from one another by predetermined amounts. Each coupler comprises a dielectric slab (18,24) defining a free space region between two periodic arrays of waveguides (16,20,22,26), each radially directed toward a virtual focal point (F₁,F₂,F₃,F₄). The arrays are configured so that their respective foci are located at a predetermined distance away from and outside the free space region to minimize phase errors caused by mutual coupling between adjacent waveguides. Specifically, the focal point of each array connected to each star coupler may be located so that it coincides with the phase center of the other array connected to each coupler. Residual phase errors may be reduced by appropriately setting the lengths of the waveguides in the optical grating between the two star couplers. The length difference between any two adjacent waveguides in the grating is not constant throughout the grating.

Abstract: A method of reducing the volume flushed from a toilet cistern (1) during a full flush. A forcing means (8, 21) is provided part way along a tube (4, 23) connected to a valve means (2,3) of a toilet cistern (1). As the water level in the cistern (1) lowers about the forcing means (8, 21) it applies downward force which closes the valve means (2,3) at a predetermined water level (12). In this way the maximum volume of water flushed from a cistern may be varied for any cistern (1) without reducing the maximum head of pressure available.

Abstract: Energization of an electric coil 45 produces flux for attracting an armature 40 of a clutch 25 into engagement with a rotor 37 in order to couple an input shaft 12 to an output pulley 13. When the coil 45 is de-energized, two angularly spaced permanent magnets 55,56 pull the armature 40 away from the rotor 37 and into engagement with fixed pole pieces 60,61 which cause a braking torque to be applied to the output pulley 13. The magnets 55,56 are located closely adjacent one another and only along a short arc of the armature 40 in order to enable the flux of the coil 45 to overcome the flux of the magnets 55,60 and effect easy release of the brake and engagement of the clutch when the coil 45 is energized.
