Abstract: A polyester fiber is provided, which does not produce a huge amount of residues during its reducing process, and shows good appearance, feeling and superior characteristics as a fiber, such as a high tensile strength and elongation. Such polyester fiber is a conjugate fiber comprising a core spinned from a polyester containing an aromatic moiety and a skin layer surrounding the core, the skin layer spinned from an aliphatic polyester. The skin layer may be easily reduced by contacting it with an alkaline solution or an enzyme, to provide a reduced fiber with good appearance, feeling and superior characteristics as a fiber.

Abstract: L'invention concerne un système de bus pour transmission série de données numériques, comprenant une pluralité d'émetteurs-récepteurs de bus (BT) adressables individuellement, connectés par un bus général uniquement bifilaire (4), par l'intermédiaire desquels des signaux de synchronisation, ainsi que des données numériques et de l'énergie sont échangés entre les BT. Comme valeur d'un bit, on transmet le résultat d'une combinaison élémentaire logique (ET ou OU) des valeurs de tous les BT de même adresse émis simultanément, en même temps, à tous les BT reçus ayant également les mêmes adresses. Chaque BT présente son propre circuit de commande de temps et de synchronisation (29) possédant une base de temps (18), un compteur de bits (22), un compteur de multiplets (23) et un comparateur (24). Lorsqu'il y a conformité entre l'adresse imprimée et l'adresse jointe au bus (4), il y a transmission série, via une porte d'accès I/O (26) d'un multiplet de données numériques. Le système de bus peut être mis en service et fonctionner sans l'utilisation d'un logiciel, ce qui élimine toute erreur d'inversion de polarité lors de l'installation.

Abstract: A lightweight portable germicidal air filter (10) for home and personal use is described. The air filter (10) includes a cabinet (12) which houses an electrostatic air filter (28), an ultraviolet lamp (26) and a parabolic reflector (36), or a convex lens (54) for focusing the ultraviolet radiation emitted by the lamp on an upstream side of the air filter. The reflector or the lens are constantly oscillated to systematically sweep the upstream side of the filter with germicidal levels of radiation. A fan (30, 32) located adjacent the downstream side of the filter draws air through the filter and impels it out through areas for air exhaust (20) in the side walls (16) of the cabinet. The advantage is a simple, lightweight germicidal air filter with few moving parts which is inexpensive to manufacture.

Granted: 2005-02-22
Abstract: A golf club head includes a front face arranged for impact with a golf ball, a heel portion and a toe portion. A hosel has a neck connected to the heel portion of the body. The hosel contains a bore for receiving one end of a golf club shaft, and the bore has a desired orientation relative to the body. The hosel neck has an upper surface and a lower surface, and a notch is formed in the lower surface of the hosel neck. The notch has a depth that varies along its length. A critical dimension measured between the upper surface of the hosel neck and a point on the depth of the notch is less than the outside diameter of the hosel. This permits the desired orientation of the bore to be adjusted by bending the hosel neck at the notch.

Abstract: The present invention relates to improved methods of generating polynucleotide sequencing reaction products from cycle sequencing and relates to various instruments and reagents for use in the subject methods. The use of "step-down" thermal profiles in conjuction with cycle sequencing is described. Step-down thermal profiles are formed by combining several thermal cycle sets such that the annealing temperature of each thermal cycle set is less than the annealing temperature of the preceeding thermal cycle set. One embodiment of the invention is a method of generating a plurality of polynucleotide sequencing reaction products in parallel by subjecting a plurality of sequencing solution preparations to a step-down thermal profile, i.e., exposure to repeated thermal cycle sets, each thermal cycle set having an annealing temperature that is lower than the annealing temperature of the annealing phases of the preceeding thermal cycle set. Other embodiments of the invention include systems for generating a plurality of polynucleotide sequencing reaction products in parallel. The systems comprise (i) a programmable thermal cycler programmed to perform a step-down thermal profile and (ii) a plurality of polynucleotide sequencing preparations. Additional embodiments of the invention include sets of polynucleotide sequencing reaction preparations that may be used in the methods of the invention. Another aspect of the invention is a device for generating a plurality of polynucleotide sequencing reaction products. The devices of the invention include (i) a plurality of polynucleotide sequencing reaction preparation chambers, each chamber containing a sequencing primer, (ii) a common fluid entry port, and (iii) a fluid dispensing channel, the channel connecting each of the sequencing reaction preparation chambers to the common fluid entry port. At least two of the sequencing primers in the device have Tms different from one another by at least 2 °C.

Abstract: A set of driver bits for Robertson screw fasteners includes driver bits (10a-d) whose shaft bodies (12a-d) have distinctive markings thereon corresponding to respective sizes of working tips (14a-d) of the driver bits. These distinctive markings are consistent throughout a family of sets. In one embodiment the distinctive marking are different colors, with each different color corresponding to a working-tip size. The colors are applied only to shaft bodies (36a-d) of som e of the driver bits by plating the shaft bodies with zinc layers (22) and then dying the outer surfaces of the zinc layers with color dye (24). This coloring is carried ou t before the shaft bodies are connected to their respective working tips. Once the outer surfaces (20) of the shaft bodies are thusly colored, the respective working tips are swaged to the shaft bodies to thereby form color-coded Robertson driver bits. In anoth er embodiment, the distinctive markings are surface-irregularity rings (32) extending about the elongated shafts, with the least number of rings corresponding to the smallest size working tip and the most number rings corresponding to the largest working tip.

Abstract: A signal amplification system involves decomposing a signal into two or more parts, amplifying the parts and then combining the amplified parts to produce the amplified signal. The decomposition can be done such that the resulting parts have characteristics that are amenable to efficient amplification. For example, decomposition of the signal to be amplified can be done using at least one threshold. The first part of the signal to be amplified can be formed by the portion of the signal within the threshold. As such, because the first part forms a signal with a lower PAR, the first part of the signal can be amplified more efficiently than the original signal. The second part of the signal can be formed by the portion of the original signal beyond the threshold. Because the second part is mostly zero, the second part can also be amplified efficiently, for example with a class C type amplifier which does not dissipate any energy when the input signal is zero.

Abstract: The coating composition comprises inorganic oxide, e.g., silica, in combination with a binder system comprising a mixture of a water soluble polymer and a non-ionic latex polymer. The composition may contain optional dye mordant (e.g., cationic polymer). It is found that the combinations of these components result in relatively high solids formulations (e.g., greater than 20 % by weight) with relatively low viscosity (less than 5000 centipoise), do not exhibit coating dusting, a nd give exceptional ink-jet printability. These formulations are especially suitable for preparing on-line formulations because they can be formulated to have a viscosity less than 2000 centipoise. Preferable embodiments for on-line coatings have a viscosity less than 1000 centipoise.
