Filed: 2007-10-05
Abstract: A semiconductor-based optoelectronic device such as a solar cell has an n-type layer and a p-type layer, together forming a p-n junction. Contact regions are formed on the device, with light-receiving regions between contact regions. A window layer is formed over the n-type layer or the p-type layer at the light-receiving region, the window layer promoting reduced carrier recombination at the surface of the n-type or p-type layer, and/or reflection of minority carriers in the n-type or p-type layer towards the p-n junction. The device has a window protection layer formed over the window layer, the window protection layer providing protection from degradation of the window layer during manufacture and/or operation of the device. For GaAs-based devices the window layer may be Al0.9Ga0.1As and the window protection layer may be GaAs. Additionally, an AlAs etch stop layer may be provided over the window protection layer.

Title: A method of automatically controlling the display of a webpage on a device
IPC: G06Q30/02
Filed: 2008-09-05
Abstract: In this invention, if an end-user has not interacted with a displayed webpage (the “Original”) displayed on a device for more than a defined time (i.e. a period of inactivity, called the “Delay”), then the device browser is automatically forwarded or pointed to a replacement webpage (the “Destination”) designated by the user or a third party. Hence, the Original will no longer remain displayed, long after it has been read, but will dynamically forward to a new Destination.
Patent GB-8423932-D0 (GB)
Title: Human serum albumin microbial production
IPC: C12N15/00
Filed: 1984-09-21
Abstract: By means of reverse transcription of mRNA coding for a desired polypeptide, there is obtained a set of overlapping fragments of duplex cDNA, which together correspond to the whole mRNA molecule. The fragments have overlapping regions bearing sites for restriction enzymes, such that cutting and ligation gives DNA corresponding to the polypeptide. This is introduced into a vector in reading frame with a promoter. Transformation of a microorganism enables expression of the polypeptide. The construction via fragments enables large molecules to be made. Thus, human serum albumin (HSA) is produced by E. coil transformed with plasmid pHSAI. This includes DNA made from fragments derived from reverse transcription of mRNA from human liver.

Patent GB-8614592-D0 (GB)
Title: Semiconductor die-attach
IPC: H01L23/492
Filed: 1986-06-16
Abstract: A method for attaching semiconductor dies to metal package supports is characterised by the use of a homogeneous soft solder preform. The soft solder preform has a uniform microstructure which is free from contaminants, such as organic materials, as well as from intermetallics, and has a particule size below about 10 microns. Such homogeneous preforms provide a bonding layer between the semiconductor device and a metal support frame which is initially free from voids and which resists deformation and cracking during subsequent power cycling of the device. The reduction in voids and cracking, in turn, allows for uniform head dissipation in the device, eliminating hot spots and extending the life of the device.

Date Nov. 29, 1990.A respiratory filter included in a respiratory system used in anaesthesia and/or patient ventilation, comprises a two-part housing 15 and 16 having coaxial ports 13 and 14 for connection to breathing tubes. Optionally a heat/moisture exchanger 25 spans the housing in addition to a planar filter member 24 which is held between parts 15 and 16 so as to be perpendicular to the direction of gas flow through the housing. According to the invention deflectors 30 and 19 are located relative to the ports 13 and 14 so as to spread incoming gases over the opposed surfaces of members 24 and 25 in order to utilize their total surface areas, thereby reducing the overall size of the filter and reducing "apparatus dead space". Each deflector has a through bore so as to utilize also the central area of the filter. Curved fins 26 and 27 radiate from each port 13 and 14. In an alternative embodiment of the invention the housing has two ports at one end, each having an associated deflector, and the fins 25 or 27 are omitted on the housing part having the two ports.

Title: Bandwidth reduction by switched filtering
IPC: H04N7/12
Filed: 1990-11-23
Abstract: In a television system in which a signal of given bandwidth is to be transmitted over a channel of narrower bandwidth, the signal is subject to pre-filtering and subsampling at the transmitter and supersampling and post-filtering at the receiver. The post-filtering means (14) comprises three filters A, B and C in parallel which are selectable in response to the characteristics of the signal to be transmitted. In order to avoid anomalies caused by switching at the transmitter, the pre-filter (10) is a single filter with a fixed pass band equivalent to the union of the pass bands of the filters A, B and C of the post-filtering means (14). The pre-filter (10) thus effectively rejects signals of frequency, such that they would not be passed by any of the filters A, B and C.

Title: Metering device for metering at least two fluids
Inventor: HOLM NIELS ERIK
IPC: B05C17/005
Filed: 1992-09-30
Abstract: A dispensing device for dispensing at least two fluids comprises a housing (12,22) of a pistol-like configuration having an integral handle (50), in which a spring-biased trigger (60) is received. Within the housing (12,22) of the dispensing device (10), two syringes (80,81) are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover (22) of the housing is closed, the motion of the trigger (60) relative to the handle (50) is transmitted to a toothed rack which cooperates with a propeller body (70) in a ratchet-like manner. The ratchet-like cooperation allows a uni-directional motion of the propeller body (70) and prevents a motion of the propeller body (70) in the opposite direction. Provided the cover (22) is not closed, the motion of the trigger (60) relative to the handle is not transmitted to the propeller body (70), and any unintentional dispensing of fluids from the dispensing device prior to the preparing of the dispensing device for use by closing the cover (22) is consequently prevented. <IMAGE>   <IMAGE>
