Patent CA-2290916-A1 (CA)
Inventor: KUBOTA MASAHIKO
IPC: B41J2/17
Filed: 1999-11-29
Abstract: A liquid discharge head has a plurality of first liquid flow passages connected to outlets for discharging the discharge liquid, a plurality of second liquid flow passages having an element board with heating elements for generating a bubble in the bubbling liquid and corresponding to the first liquid flow passages, and movable separation films substantially and mutually separating the first liquid flow passages and the second liquid flow passages at all times, wherein the movable separation films are mutually independent individual separation films for each of the second liquid flow passages. It is possible to directly provide a flow passage wall configuring a side wall of a first liquid flow passage onto the element board by the low temperature junction by using surface activation since the movable separation films are individual separation films. The junction of the flow passage wall to the element board is surely performed and the dispersion in discharge characteristics depending on the lot of products can be restrained.

Title: Non-invasive continuous blood glucose monitoring
Inventor: BUCHERT JANUSZ M
IPC: A61B5/1455
Filed: 1998-05-18
Abstract: A method and an instrument for a continuous non-invasive detection of an analyte, (e.g., glucose) concentration in a human body tissue such as blood, is disclosed. The instrument remote sensor assembly (7) mounted in subject's ear canal continuously measures analyte concentration by detecting the infrared radiation naturally emitted by a human body. It uses an infrared detector (7) with a combination of adequate filters (6) such as, for example, a negative correlation filter or narrow band filters or other detector filter assemblies. The method and instrument is based on the discovery that natural infrared emission from the human body, especially from the tympanic membrane (1), is modulated by the state of the emitting tissue.      Spectral emissivity of human infrared radiation from the tympanic membrane (1) consists of spectral information of the tissue, (e.g., blood) analyte, (e.g., glucose).      This can be directly correlated with the blood analyte concentration, for example, the blood glucose concentration.

Title: Methods of recycling catalyst in oxidations of hydrocarbons
Inventor: DE COSTER DAVID C
IPC: B01J19/26
Filed: 1998-09-14
Abstract: This invention relates to methods of recycling catalyst in oxidations of hydrocarbons, such as cyclohexane for example, to respective intermediate oxidation products, such as adipic acid for example, by a direct process. The catalyst remains in solution despite removal of water from the composition, since the water removal is controlled at such temperatures and such remaining water levels that prevent catalyst from precipitating. The water removal is preferably conducted before removal of the intermediate oxidation product. Also, preferably, some, and more preferably all steps of the process are conducted in a single liquid phase region.

Title: Filter for impulse response shortening, with addition spectral constraints, for multicarrier transmission
Inventor: HARIKUMAR GOPAL
IPC: H04L25/03
Filed: 1999-04-05
Abstract: A channel in a multiple carrier communication system is equalized by computing a desired spectral response, shortening the impulse response of the channel so that a significant part of an energy of the impulse response is confined to a region that is shorter than a target length and filtering the signal based on the desired spectral response. A  multiple carrier communication system may include a primary impulse shortening filter that receives an output signal of an analog to digital converter and accepts coefficients. A secondary impulse shortening filter may receive the output signal of the analog to digital converter, output an output signal, and pass coefficients to the primary impulse shortening filter. A reference signal generator may output a reference signal. A comparator may compare the output signal and the reference signal and output a resulting error signal. An adaptive processor may compute coefficients for the secondary impulse shortening filter based on the error signal.
