Patent GB-2367436-A (GB)
Title: Bulk acoustic resonators and a ladder filter made thereof
Inventor: RUBY RICHARD C
IPC: H01L41/22
Filed: 2001-04-06
Abstract: A ladder filter (fig 12) is formed of acoustic resonators 42, 62. Each resonator has its own cavity 48, 76 and a bottom electrode 44, 64 spanning the entirety of the cavity. The cavity is formed by etching a depression into a substrate, filling the depression with a sacrificial material (52, fig 7), depositing the piezoelectric 54 and electrode layers 58 that define an FBAR and then removing the sacrificial material from the depression. An SBAR may also be defined (92, fig 13). Sacrificial material release holes (60, fig 10) are limited to the periphery of the depression. Preferably, the bottom electrode 44 is the only electrode that spans the cavity, thereby limiting the formation of parasitic FBARs or SBARs. The bottom electrode includes a serpentine edge that leaves a portion 66, 68 of one side of the cavity free of overlap by the bottom electrode, so that a top electrode may overlap this portion.

Title: Process for improving leakage and dissipation factor of solid electrolytic capacitors employing conductive polymer cathodes
Inventor: HAHN RANDOLPH STEPHEN
IPC: H01G9/025
Filed: 1999-09-29
Abstract: The adhesion of a conductive polymer film to an oxidized porous pellet anode is improved by the incorporation of a silane coupling agent in the polymer impregnating solution. The incorporation of the silane coupling agent also decreases leakage current and dissipation factor. Suitable silanes are those of the general formula (R<SP>1</SP>-R<SP>3</SP>)-Si-(OR<SP>2</SP>)<SB>3</SB>. Each of R<SP>2</SP> and R<SP>3</SP> is a C<SB>1</SB>-C<SB>6</SB> alkyl group such as methyl, ethyl, or propyl. R<SP>1</SP> can be chosen from a wide variety of organic functional groups such as epoxy, glycidoxy, amino, and pyrrole. The most preferred silane is 3-glycidoxypropyltrimethoxysilane.

Title: A radiator mounting jig
Inventor: GROVES STEPHEN
IPC: F24D19/02
Filed: 2001-05-17
Abstract: A jig 10 which allows a radiator 50 to be mounted against a plasterboard false wall 40 but without mounting the radiator 50 directly to the plasterboard wall 40 and therefore preventing damage to the plasterboard wall 40 comprises an elongate base portion 11 and two upstanding portions 12 mounted on a brick wall 20 by screws 21. Assymetrically arranged elongate rods 30 which may be threaded are removably located by nuts welded to the upstanding portions 12 and extend perpendicularly away from the brick wall 20 and protrude though holes drilled in a plasterboard wall 40 so that 1-section brackets 51 which are attached to the radiator 50 can be mounted and secured in place by nuts. Spaced apart pipework 60 at either end of the base portion 11 is connected and corresponds to the spacing between an inlet and outlet of the radiator 50 and extends though the plasterboard wall 40 and holes 70 in the jig 10 to connect to a boiler. Rubber grommets in holes 70 prevent metal to metal contact of the pipes 60 and base portion 11, and because the ends of the base portion are not fixed to the wall 20 they are bent to accommodate the pipe 60 behind the ends. The jig 10 may be made of sheet metal or durable plastic and of a size to correspond to various sizes of radiator.

Title: Amplifier linearisation utilising amplifier return signal
Inventor: WARR PAUL ALUN
IPC: H03F1/32
Filed: 2001-12-06
Abstract: A signal processing element for a high frequency application for minimising distortion introduced to an input signal by a main amplifier. The distortion generated in the main amplifier is present in a return signal originating from the main amplifier input and also in a main signal originating from the main amplifier output. The return signal is isolated from the input signal to form an error signal and then magnitude-phase conditioned. A comparison of the main signal and the error signal at a coupler results in a linearised output signal with any intermodulation products suppressed. Alternatively, the amplifier can be replaced by other non-linear radio frequency devices, for example, a mixer or a gain/phase controller.
