Title: Embossing device for two-dimensionally expanded material
IPC: F16C13/04
Filed: 2000-03-17
Abstract: The embossing rolls (1, 4) of embossing devices (14) that are used for processing two-dimensionally expanded material, especially in the packaging industry, can be exchangeably configured if they are mounted in suitable exchanger units (2). An exchanger unit can be configured, for example, as a tube (2) with terminal locating surfaces (8, 9). The stand (13) of an embossing device (14) has corresponding seats (11, 12) that are adapted to the respective exchanger unit (2) with high precision. The embossing roll (1, 4) that is received in an exchanger unit (2) is thus in its working position once it is inserted and the locating surfaces (8, 9) of the fixing elements are received by the pertaining seats (11, 12) and no further adjustment needs to be carried out. Especially the driven embossing roll (1) of such an embossing device (14) can be exchanged with substantially less effort, which makes it possible to quickly perform maintenance work and rearrange the production.

Title: Moving picture encoding method
Inventor: SO YUN SEONG
IPC: H04N19/132
Filed: 2002-01-08
Abstract: PURPOSE: A method for encoding a motion picture is provided to make the quantity of bits between frames or quality of reproduced images uniform after a scene change occurs or an abrupt motion appears. CONSTITUTION: Motion-picture encoding using periodic intra block update is carried out in such a manner that a counter value of a block that is determined as an intra mode in one frame according to encoding mode decision is not initialized to zero but randomized within a predetermined range. The predetermined range for randomization is set to (0, R/k), where k is an integer larger than 1 and R corresponds to an intra block update period. In the case that the number of blocks determined as the intra mode is p and counter values of the blocks are randomized to values between the range (0, R/k), the intra blocks are dispersed in the range of (f+(k-1)R/k, f+R) so that only kp/R block counters per frame are intra-updated at period R.

Title: Method for demodulating wobble signal on optical disc
Inventor: JU WON BAE
IPC: G11B7/004
Filed: 2002-04-19
Abstract: PURPOSE: A demodulating method for wobble signals of an optical disc is provided to carry out speedy demodulating operation of wobble signals by a simple hardware and algorithm, and compensate the detection error of the wobble signals caused by the defects of the disc. CONSTITUTION: A demodulating method for wobble signals of an optical disc includes the steps of initiating a count value of a bit clock output from a clock detector to zero(S30), and checking whether a bit clock output from the clock detector is detected(S31). If detected, a level of a peak detecting signal output from a peak detector is checked when the bit clock transits from a high level to a low level. The bit detector outputs a data bit of '0' or '1' according to the level of the bit clock and such output data bits are temporarily stored in sequence(S32). The bit detector accumulates and increases the count value of the bit clock output from the clock detector by one(S33). When the count value of the bit clock is '56', the data bits are compared with 8 ADIP units(S34). As equal ADIP units are detected, packet data corresponding to the detected ADIP units are stored in sequence(S35). In the other case, a detection error of wobble signals is determined to have been generated by defects of an optical disc, so that a current packet data position is checked(S36) and a pseudo packet data is generated correspondingly(S37). An address decoder temporarily stores such generated 83 packet data(S38) and 83 ADIP units are generated with reference to the packet data(S39).
