Abstract: The present invention relates to the refinement of an assembly structure of a hubbed door leaf installed with glass, which comprises a first door skin with an opening, a second door skin with an opening, a top lacing material, a bottom lacing material, a left lacing material, a right lacing material, a handle reinforcement member and the ejected frame with multiplayer glass hold-down. The door skin with the opening can be manufactured to be various shapes such as square, rectangular, circle, ellipse, and semicircle depending on different mold. When assembled, the lacing materials are mounted to the edges of the first door skin by an adhesive. The left and the right lacing materials are position-bonded, by ribs, to the flush-sided door skin. The top and the bottom lacing materials are positioned through the milled notches at the top and the bottom ends of the left and the right lacing materials. A reinforcement member is disposed at the handle position to enhance the mechanical strength of the handle while locked. The openings of the two door skins have halving structure to halve- joint together when assembled to form a closed cabin therebetween. The bottom lacing material is then drilled with a hole through which the ammonium polyester foaming plastic is filled into the cabin to finish the assembling of the said door.
Patent CA-2344263-A1 (CA)
Inventor: ZHOU SHUTONG
IPC: H03F3/60
Filed: 1999-09-09
Abstract: A plurality of amplifiers are connected in cascade to form an in-line pre-distortion circuit. The amplifiers are unbalanced in that each amplifier stage in the circuit has two DC voltage rails which are independently controlled to provide different, i.e. offset, DC voltage levels to the unbalanced amplifiers. This unbalance in the amplifiers generates pre-distortion in a signal which can be used to cancel the inherent distortion caused by a non-linear device which subsequently processes or transmits the pre-distorted signal. Control of the DC voltage offset in at least one of the amplifier stages is necessary to match the pre-distortion to the inherent distortion being corrected. A tilt circuit can be used in cascade with the plurality of amplifiers (in front of the RF amplifiers) to compensate the amplitude change caused by the unbalanced RF amplifiers. Either side of the DC voltage can be changed in order to correct for either sublinear or superlinear laser diode curves.

Filed: 2001-07-06
Abstract: The invention has for its object to provide a thin-film EL device comprising a multilayer dielectric layer formed of a lead-based dielectric material by a solution coating-and-firing process, which provides a solution to problems in conjunction with its light emission luminance drops, luminance variations and changes of light emission luminance with time, thereby achieving high display quality, and a process for the fabrication of the same. This is accomplished by the provision of a thin-film EL device comprising a patterned electrode stacked on an electrically insulating substrate and a dielectric layer having a multilayer structure wherein at least one lead-based dielectric layer formed by repeating the solution coating-and-firing process once or more times and at least one non-lead, high-dielectric-constant dielectric layer are stacked together, and the uppermost surface layer of the dielectric layer having such a multilayer structure is defined by the non-lead, high-dielectric-constant dielectric layer.

Patent CA-2359686-A1 (CA)
Inventor: PTASINSKI KRISTOFFER
IPC: G01R31/36
Filed: 2000-01-20
Abstract: A method enables digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto. The digital, serial communication comprises transmission of bytes (300) consisting of a number of bits. The method comprises the steps of transmitting a byte from a first one of said electronic device and said battery, receiving said byte in the other of said electronic device and said battery, and retransmitting said received byte unchanged. Hereby, it is possible to compare the contents of the returned byte with the contents of the byte originally transmitted, and thus ensure that the byte was transmitted correctly. This simple procedure makes other error handling procedures such as parity bits unnecessary.

Abstract: The holder means 2 holds active library information 2-1 to 2-m, determining the retrieval sequence of active library storage areas to be retrieved, every program types C1 to Cm. The selector means 5 selects the active library information 2-1 corresponding to the type C1 of the program 4-1 in execution. The dynamic linker 3 retrieves the library X1 with an identifier x specified from program 4-1 in execution, in accordance with the retrieval sequence of the active library storage areas 1-1 and 1-2 indicated by the selected active library information 2-1, and then links it to the program 4-1. When the program 4-2 of the program type C2 issues a link request specifying the same identifier x, the active library information 2-2 is selected and the active library storage area 1-2 is first retrieved. Thus, the library X2 with the identifier x is linked to the program 2-2.

Title: Hybrid glycosylated products and their production and use
Inventor: GAISSER SABINE
IPC: A61P31/04
Filed: 2001-04-17
Abstract: The present invention relates to hybrid glycosylated products, and in particular, to natural products such as polyketides and glycopeptides, and t o processes for their preparation. The invention is particularly concerned wit h recombinant cells in which a cloned microbial glycosyltransferase can be conveniently screened for its ability to generate specific glycosylated derivatives when supplied with polyketide, peptide, or polyketide-peptides a s substrates. The invention demonstrates that cloned glycosyltransferases when  rapidly screened for their ability to attach a range of activated sugars to a range of exogenously supplied or endogenously generated aglycone templates, show a surprising flexibility towards both aglycone and sugar substrates, an d that this process allows the production of glycosylated polyketides in good yield. This overcomes the problem not only of supplying novel sugar attachments to individual polyketides, including polyketides altered by genetic engineering, but also of increasing the diversity of polyketide libraries by combinatorial attachment of sugars.
