Abstract: Asynchronous computation commands sent from a command control are held in a command queue.  The executable command is selected and supplied to a pipelined asynchronous computing unit.  A status area is assured for each command held in the command queue and pipeline bits indicative of a progressing state of the execution of the command in the asynchronous computing unit are stored.  A queue verifier discriminates the pipeline bits and verifies that a plurality of pipeline stages does not exist in the status area of the same command and that a plurality of pipeline stages does not exist among the commands, thereby guaranteeing the correct order and operation of the execution of the commands.

Abstract: The present invention relates to a system that is part of a user-pay system and is used to identify stretches of a route that are travelled by a moving object within a network of roads, or established geographic zones that are entered by the object.            In order to create an accounting system that can be used universally as far as possible and which requires little outlay for infrastructure, it is proposed that a system that is installed independently is used for the wireless transmission of the information that is used to identify the current geographical position of the object; and in that the moving object carries a receiving system for the wireless transmitted information as well as a memory device for the temporary storage of data; and in that within the object there is a second memory device for permanently storing preset data; and in that the object also carries a comparison device for  comparing this data. It is also proposed that an identification system for identifying the particular stretch of a route that has been travelled is also carried by the object, and that a mobile memory module that can be connected to the identification system is also used.

Filed: 1995-02-15
Granted: 2000-05-02
Abstract: An apparatus and method for applying textile treatment finishing agents to garments or garment work pieces is provided.  The apparatus includes a rotating drum (32) and a nozzle (15) for generating a fine mist or fog of textile treatment agents inside the rotating  drum (32).  The apparatus  can  be constructed as a dedicated  processing  machine, or a conventional,  industrial washer or dryer  can  be fitted with an appropriate nozzle (15) and feed lines (16, 19)  to  provide a dual  purpose machine which can be used for  its  originally intended  purpose, and can be selectively used for  applying  textile treatment agents.  Uniform coverage of the  surface of the garment is assured  by tumbling the garments through the fog  created by the nozzle means (15). By controlling the size of the  droplets, and the time during which mist  or fog is  generated, the amount of chemical agent  absorbed by the garments can be controlled.  The use of the finely divided, air dispersed liquid agent avoids wasted processing chemicals and permits the use of more  concentrated chemical agents.

Granted: 1999-11-09
Abstract: A flyback transformer (FBT) driving apparatus for video display appliances which can prevent deterioration of the FBT efficiency caused by excessive horizontal frequency input. The FBT driving apparatus employs a PWM-type circuit to evenly maintain the Vcc power supply provided to the primary winding of the FBT irrespective of the excessive horizontal frequency input. The FBT driving apparatus makes use of the horizontal frequency per se in the low frequency band, while dividing the horizontal frequency by a half in the high frequency band to enable operation of the FBT by means of ordinary rectifying diodes even in the input of the high horizontal frequency and to prevent deterioration of the FBT efficiency caused by input of the high horizontal frequency.
