Abstract: A method for mapping 2N message N-tuples into 2N+1 codeword (N+1)-tuples is developed. The 2N+1 codeword (N+1)-tuples are categorized into M subsets of codeword (N+1)-tuples, wherein M is an integer larger than 1, each subset G has NG codeword (N+1)-tuples and the total number of codeword (N+1)-tuples in the M subsets is 2N. Each subset G has a predetermined number KG of lower bits and a predetermined number (N+1−KG) of higher bits, and the number of lower bits in every codeword (N+1)-tuple in any subset is not equivalent to that of lower bits in every codeword (N+1)-tuple in any other subset. The 2N message N-tuples are matched with the 2N codeword (N+1)-tuples in the M subsets, respectively, in one-to-one correspondence to generate a lookup table.

Abstract: An encoder demodulates an input signal of a program. Main data of the program are recorded in a recording medium as main information in the form of data blocks. Auxiliary information of the program are recorded in the recording medium as packs having a fixed length shorter than a length of the data block. A memory temporarily stores designated auxiliary information of a concerned program in connection with identification information of the recording medium in response to a recording of the main data into the recording medium. A controller causes the encoder to read all of the auxiliary information of the program stored in the memory at a time. The readout auxiliary information have same identification information corresponding to the same recording medium. The readout auxiliary information are modulated as packs and recorded in the subcode areas of the recording medium having the corresponding identification information.

Abstract: Dangerous packages, such as high activity nuclear packages, are placed in adjacent compartments (22) formed in the body (10) of transport packing. The compartments (22) are closed by individually closure plugs (28) and by a common cover (34) that works in cooperation with one face (17) of the body (10) with three seals in series. Connectors installed on the cover (34) and opening up between the seals, are used to make an inspection of the helium confinement. The steel inner casing (24) in each compartment (22) is doubled up on the outside with a copper weld free casing (50). This arrangement significantly improves the confinement inspection, enables a global helium inspection, and if necessary can be used to isolate an unsealed compartment (22).

Here, the second picture unit precedes the first picture unit and display locations of the first and second picture units are identical to each other. The writing operation goes into a waiting mode while the reading operation is being executed.
