Abstract: The apparatus uses a motor driven rotating drum (22A) for supporting on its periphery a magnetic tape (2) which has a 180° wrap on the rotating drum following a skewed or helical path with respect to the plane of rotation of a plurality of magnetic heads (32, 34), i.e., the magnetic heads follow a helical scan path on the magnetic tape recording surface. The rotating heads (32, 34) are mounted on a separate ring (44) having a pivotable connection (50, 52) with a motor drive shaft (6) whereby the rotating heads are pivotable independently of the rotating drum (22A) to provide a variable angle between the plane of rotation of the magnetic heads (32, 34) and the surface of the magnetic tape. This variable angle changes the angle of the helical scan path on the magnetic tape and is preset for a particular tape speed to produce a maximum packing density of the recorded information by utilizing an entire tape scan path.

Abstract: Delay that a packet experiences in a network node is measured by employing a single local time signal in the node, and by separating a time stamp update function into a network node entry time stamp function and a network node exit time stamp function. The node entry time stamp function is to generate (via 208) a packet originate time value referenced to the local time signal value upon the packet entering the node. This packet originate time value is inserted (via 208) into a packet header time stamp field to be transported through the node. The node exit time stamp function is to generate an updated time stamp value (via 1109) from the packet originate time value from the header time stamp field and the local time signal value upon the packet exiting the node. The updated time stamp value is inserted (via 1106,1107) into the packet header time stamp field in place of the packet originate time value.

Abstract: A printing process for a thermal transfer type multicolor printer repeatedly transfer a plurality of color ink, such as yellow, magenta and cyan color ink, in turn on a printing paper (1) so as to obtain a multicolor printed paper (1c). After every time when one color ink is transferred to the printing paper (1), the printing paper (1) lapped with a multicolor ink film (2) is fed forward to a predetermined separation position at a predetermined printing speed under a pressure applied between a thermal head (7) and a platen roller (6). Thereafter, the thermal head (7) is separated from the platen roller (6) so as to prevent the remaining heat of the thermal head (7) from affecting to the multicolor ink film (2), so that the ink wax of the multicolor ink film (2) is prevented from being melted and working as an adhesive agent for the printing paper (1) and the multicolor ink film (2). Hence, the printing paper (1) can be separated from the multicolor ink film (2) with ease. Then the feeding speed of the printing paper (1) is made slower than that of the multicolor ink film (2) so as to prevent the multicolor ink film (2) from slackening. Thereafter, the printing paper (1) is completely separated from the multicolor ink film (2) and the transferred ink quantity is not changed in this separation process (S5, S10 and S15; S6, S11 and S16), thus, the multicolor dot printing can be performed with accuracy.

Abstract: On encoding an original picture signal comprising signal portions representative of original pictures, respectively, a contrast detecting unit (41) detects a measure of contrast in each picture in response to signal blocks representative of block areas, respectively, which have a common size in the picture in the manner known in transform encoding. Such measures are variable in a predetermined number of stages. With reference to the stages, a picture encoding parameter determiner (72) determines picture encoding parameters. Supplied with the encoding parameters, a picture encoder (71) encodes the original picture signal into an encoded picture signal. Inasmuch as the measures are detected in consideration of the signal blocks, the encoding is carried out on the signal blocks in effect. The contrast detecting unit, as herein called, preferably divides the pictures into a background region and a picture or non-background region so that the encoding parameters are determined with additional reference to the regions. The measures may be detected either among the block areas of each picture or among picture elements of each block area. More preferably, a complexity detecting unit is used in addition to the contrast detecting unit. The picture encoder is typically either a transform encoder or a predictive encoder.

Abstract: This invention relates to articles for cleaning, buffing, conditioning, or restoring surfaces. 
     Abrasive articles made from nonwoven fibers have long been used for cleaning floors and other surfaces. Although previously known nonwoven abrasive articles are extremely useful for the purposes for which they are intended, they rapidly lose their efficiency as they become saturated with dirt. 
     This invention provides an abrasive article comprising an open, lofty nonwoven web comprising helically crimped synthetic organic fibers. The article can optionally contain stuffer box crimped fibers and melt bondable fibers. 
     The presence of helically crimped fibers brings about greater durability and greater capacity for absorbing debris.
