Described herein is a dynamic memory. An N channel type voltage clamp MOSFET is provided which has a drain supplied with a supply voltage supplied from an external terminal, a gate to which a boosted constant voltage is applied, and a source which outputs a constant voltage. The clamp voltage outputted from the source of the voltage clamp MOSFET is supplied to a common source line for each of P channel type amplification MOSFETs constituting a sense amplifier via a P channel type first power MOS...

A method and related apparatus and software of detecting anomalies in a stream of data values. The method comprises the steps of: receiving a data value on the stream of data; calculating a new weighted average responsive to the received data value, a previously stored weighted average associated with the stream of data, and a decay rate in the range of 0 to 1; and calculating a new measure of deviation from the new weighted average responsive to the new weighted average, the data value, a previ...

Mixer comprising a housing having filling and emptying openings, two corotating stirrers and drivers for the stirrers, one of the stirrers being arranged centrally in the housing and having at least a drive shaft and at least one transverse beam fitted to the drive shaft and at least one stirring arm fitted at their ends to the transverse beam.

A file system for file sharing includes a web server that creates a temporary directory for each session between the web server and a client computer. When the client computer requests a file located in a file server, the web server creates a symbolic link to the file in the temporary directory and a web page including an URL to the symbolic link. The web server transmits the web page, and therefore the file, to the client computer. Client computer can also upload files to the web server. The we...

A dynamic damper for damping vibration of a rotary shaft. The dynamic damper includes a tubular mass member and a rubber elastic member. The rubber elastic member includes an attachment tube press-fitted onto the rotary shaft and an arm. The attachment tube is disposed coaxially with the mass member but nearer to an axial center thereof than the mass member. The arm connects the attachment tube to the mass member. The attachment tube includes a tubular support portion connected to the arm, a tub...

The invention relates to a dynamic mixer, comprising a housing (10) and an inner body (11) which can be rotated about a common axis in relation to each other and which form a mixing chamber (12); a back shut-off element (20) which delimits the mixing chamber (12) and which has inlet openings (21) for guiding in the components to be mixed, a front outlet (24) for delivering the mixture and a drive element (17) which is located on the rotatable part of the mixer. The inner body (11) is connected t...

The present invention provides a novel execution environment for optimizing the efficiency of the distributed object system. In one embodiment, the invention includes a compiler with ability to interpret, just-in-time compile or pre-compile any object of the distributed object system. An object is provided in a tagged file format that allows a compiler to identify critical sections of the object code for immediate one-time compiles while delaying compiling of the non-tagged, non-critical code un...

A seal is disposed between a rotating part and a stationary part. At least one of the parts is provided with projections which protrude into the seal gap. The seal gap (5) extends approximately radially so that both parts are provided with projections which extend in an axial direction, which are located concentrically in relation to the axis of rotation of the rotating parts and which engage with each other. Said projections are configured in the form of rows of blade-like elements. This effect...

A dynamic seal assembly has an outer carrier member formed of one-piece having an outer flange, an inner flange, and an intermediate portion presenting first and second shoulders. A PTFE seal member is disposed about the second shoulder and is compressed axially by a case member which, while the PTFE seal is compressed, is staked to the carrier to secure the seal. The carrier has an axially outwardly facing annular pocket accommodating a foam dust excluder into which a flange of a wear sleeve ex...

A dynamic damper includes a cylindrical mass metal element, a cylindrical elastic-body attachment portion, a cylindrical elastic-body connection portion, and an elastic-body covering portion. The elastic-body attachment portion is formed from a rubber elastic body and coaxially disposed inside the mass metal element while a predetermined radial distance is maintained therebetween. The elastic-body connection portion is formed from a rubber elastic body and disposed between the mass metal element...
