    摘要： A housing includes a body having an opening. The body includes a peripheral portion that abuts on the opening. A cover covers at least a part of the opening. A seal is sandwiched between the cover and the peripheral portion of the body. At least one of the cover and the peripheral portion of the body includes a corner portion and a linear portion. The corner portion has a first shape that defines one of a gap between the cover and the peripheral portion of the body and a width of the seal. The linear portion abuts on the corner portion. The linear portion has a second shape that defines the one of the gap between the cover and the peripheral portion of the body and the width of the seal. The second shape is different from the first shape of the corner portion.

    摘要： An encoding method encodes by using a quasi-cyclic code having a code length of n=m n0 and an information word length of k=m k0. The method includes the steps of: creating a systematic code with as many as (n0−k0) parity bits inserted therein in units of an information word k0; making all combinations of (n0−k0) parity bit positions that may occur in units of no bits; describing many of m×m cyclic matrices by rearranging the sequence of columns in a parity check matrix in the combinations; subjecting the parity check matrix to elementary transformation to create a unit matrix in which (n−k)×(n−k) matrices made up of the columns corresponding to the parity bit positions; regarding the transformed matrix as a first matrix and this matrix minus the unit matrix as a second matrix; and allocating (n−k) bit positions for the parity bits in such a manner that the number of non-zero elements included in the second matrix is minimized.

    摘要： A code sequence is encoded using a code conversion table in which the parity of the code sequence varies until the code states become equal to each other. The code word assignment used in this code conversion table is such that the decoded code word constraint length is 3 blocks and q0≠q1 for an arbitrary information sequence is satisfied even if a DC control bit is inserted at any of the first and second bits of an information word. Code states s0 and s1 when information sequences d0 and d1 resulted from insertion of provisional DC control bits 1 and 0 inserted at the top of an information sequence “1, 1, 0, 0, 0, 1, 0” are encoded starting with a state 3 according to a predetermined code conversion table are equal to each other, namely, s0=s1=6, in a third block, and two's complement q0 of a sum of code sequences c0 up to a time when the code states are equal to each other is “0” while two's complement q1 of a sum of code sequences c1 up to that time is “1”. That is, the condition that q0≠q1 is met. The code sequence can be applied to a recorder/player or encoder.
