A method for handling failures in an electronic price label (EPL) system (10) automatically diagnoses failures, and may additionally automatically contact a remote support system (32). The method includes the steps of wireless transmitting a status request to a communications base station (CBS) (15) and to an EPL (18) by a computer (12), receiving a status reply from the CBS (15) and the EPL (18) ...

The turbine steam outlet side is provided with a cut-off valve to the condensers and valves and a pipe conduit from the turbine outlet to a heat exchanger positioned on the deck. Steam is conducted so that it first passes through the turbine driving the pump which circulates the oil in the tanks through the heat exchanger placed on the deck. In a further version, the condenser is replaced entirely...

An ATM layer device for interfacing between a physical layer device and an ATM switch, which includes means for prepending and postpending of switch routing information to cells destined to enter the switch and for removing such information from cells having left the switch

The audio bit stream generator of a high definition television (HDTV) using a personal computer (PC) is comprised of: a hard disk (10)storing audio data for the HDTV encoded by a computer sham examination; a main memory (20A) reading an amount of given length data of audio data to output it to an input/output bus (20B) of the personal computer (20); and an interface card unit (30) comprising an ad...

A railroad ballast broom vehicle uses a double or split auger to move ballast received from a rotary core broom. The auger has various features to minimize the risk of it jamming on ballast which it moves to the field side of rails of the railroad bed which is being swept. Flex plates are used to mount broom drive hydraulic motors to minimize or avoid problems which might otherwise be caused by sl...

Apparatus for repeated automatic execution of a thermal cycle for the treatment of a sample, especially a biological sample, comprises means (6) defining a pathway which is physically closed throughout the treatment and within which the sample is resident throughout the treatment. Means (3, 4, 11, 12) are provided to move the sample between different positions along the pathway and (7, 15, 16) to ...

A surgical stapler having a supporting frame, including a stationary jaw having an anvil, a movable jaw, a replaceable staple cartridge carried by the movable jaw, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil in a manner to enable the surgeon to substantially simultaneously place one or more ro...

Disclosed is negative mask manufacturing method which is essentially used for a semiconductor laser diode and a semiconductor waveguide etc. The negative mask manufacturing method comprises the steps of performing a first light exposure by using a laser lithography after performs spin coating with a photoresist(10) on a substrate coated with crom(Cr), developing after performs a second light expos...

An exhaust gas recirculation system for a compression ignition engine and a method of controlling exhaust gas recirculation in compression ignition engines are disclosed. The method and apparatus are adapted to the control of exhaust gas recirculation in diesel and/or multifuel (e.g. diesel and natural gas) engines. The apparatus includes a first pressure sensor for sensing an absolute gas pressur...

A hair shampoo composition is provided, which comprises, in addition to water, one or more C6 to C34 acyl lactylates and one or more alkyl polyglycoside(s) where the alkyl group contains 5 to 30 carbon atoms and the ratio of acyl lactylate to alkyl polyglycoside is greater than or equal to 1:6. The shampoo provides a foam which is less coarse than that normally associated with compositions contain...

Processing of picture image compression coding is divided into a plurality of processing steps and programs for the respective steps are stored in a memory. Based on capacity of the memory, at least one of a number of frames, a number of lines and a number of block lines is set as a division unit by which each step conducts processing. Processing corresponding to a program stored in the memory is ...
