A suppressing message ID correcting/ deleting part 30 corr...

PURPOSE:To easily fix the menu sheets, slips, etc., onto a tablet or to remove them out of the tablet by providing a magnetic attracting layer on a tablet together with the lock bars made of a ferromagnetic material. CONSTITUTION:A magnetic attracting layer 2 is buried into an approximately center position of the upper plate of a case 13 of a tablet 1 so that the attracting surface (upper surface)...

PURPOSE:To omit the connection of a position indicator to improve operability and to detect the position with excellent accuracy, by using a position detecting part where many loop coils are set in parallel with each other and a position indicator containing a tuning circuit. CONSTITUTION:The loop coils 11 of a position detecting part 1 are driven by the AC signals of the prescribed frequency. The...

PURPOSE:To obtain a data processing function that is suitable for the relevant specifications just with designation of an input/output device, by separating the input/output devices from the data items related to these devices. CONSTITUTION:The input/output data processing is separated between the input/output devices 3 and the data items. A memory table contains a position information memory area...

PURPOSE:To set a terminal equipment at a specific function by storing the data in a recording medium to specify the data item setting data and reading said data out of the recording medium at the side of the terminal equipment. CONSTITUTION:A processing program 1 including an instruction word for execution of the prescribed processing is previously stored at the side of a terminal equipment 10 and...

PURPOSE:To perform restart processing at a high speed when an on-line breakdown occurs by separating a transaction journal from an interactive journal. CONSTITUTION:A recovery journal is divided into a transaction processing journal and an interactive processing journal when the on-line breakdown occurs. As a result, the mutual influence is avoided between the gray zones of both transaction and in...

PURPOSE:To oscillate all the semiconductor lasers of an array in a state of phase lock by forming at least one irregular sections adjacent to both sides of an irregular section constituting an optional guide. CONSTITUTION:A semiconductor laser array element is composed of a plurality of optical guides shaped in response to irregularities 4 formed onto a substrate 1, and at least one irregular sect...

A method for reducing image artifacts due to signal variations in the course of examining a subject using nuclear magnetic resonance (NMR) techniques includes the acquisition of NMR data for imaging the object. The NMR data is composed of a number of views. The acquisition of each view includes the implementation of a pulse sequence to generate an NMR signal and application of a magnetic gradient ...

An optical axis adjusting apparatus of a projector type headlight (10) including a bracket (34, 36) for supporting a frame (22) integrally fixed with the lamp unit composed of a reflector (12), a light source (16), a shade (18) for shaping the light reflected by the reflector (12) and condensed at a predetermined region suitably, and a convex lens (20) for forwardly projecting the shaped light. Th...

Intermittent contacts between a flying transducer head and a magnetic record medium are monitored by detecting triboelectric charges generated by such contacts. Different amounts and polarities of triboelectric charge are generated by different materials on the surface of the record medium. The flight of the head when it is out of contact with the record medium can be monitored by detecting v...

Structural element for a soundproofing wall or coating for such a wall, which is produced from concrete mixed with aggregates, said structural element or said coating being produced from compacted lightweight concrete of bulk porosity with at least some of the aggregates in the form of granules.

A sewage treatment consists of pre-settling basin, a biological purificn. section, and a final settling basin. Some of the sewage is recycled from the final into the first settling basin by spraying it over the surface of the sewage in it. USE/ADVANTAGE - For small housing estates, large hotels or dairies with a sewage input equivalent to 50-1000 inhabitants. This helps the aeration and removes e...
