Title: Code state discrimination method and encoder
Inventor: NODA MAKOTO
IPC: G11B20/14
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To perform universal state discrimination by discriminating the state of a code end point based on a transition diagram for the state discrimination where a pertinent inhibition output code is newly assigned as an additional path to the state that the code output is inhibited. SOLUTION: As to a state transition diagram, an additional path is added to the state transition diagram of four states to generate a code where a DSV is 4, and an inhibited output code 0 is outputted to a state 3 in a state 4. When the state is tracked in accordance with the state transition diagram as of a DC free code where the DSV is so limited that the states of start and end points of a code word become elements of 1, 2, 3, and 4, the state of the pertinent code word is correctly expressed at least at the start and end points of the code word as of the code of the all DSV.  For the state transition diagram where the DSV value (or ASV) is limited to 4, the state of the end point of the code is discriminated in accordance with the state transition diagram where the pertinent inhibition output code is newly assigned as the additional output path to the state that the code output is inhibited.

IPC: H02G9/06
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To allow any positional discrepancies in the coupling portions of a handhole portion for checking or branching which comprises a pair or a plurality of U-type (A) blocks and U-type (B) blocks, even when the blocks are moved due to earthquakes, etc., by interposing flexible retractable rubbers between each U-type A block and each U-type B block. SOLUTION: A plurality of through holes of a conduit block 1 keep wires and cables inserted. In suitable places, handhole portions for checking are formed out of U-type (A) blocks 2 and U-type (B) blocks 3. The conduit block 1 and the U-type B block 3 are coupled to each other via a protection concrete 4 to form a coupling structure for eliminating any positional discrepancy between both the blocks 1, 3. When the U-type B block 3 is coupled to the U-type A block 2, flexible retractable rubbers 5 are interposed in an attached way between both the blocks 2, 3. Since the flexible retractable rubbers 5 are deformed suitably in response to the movements of both the blocks 2, 3, even through any positional discrepancy between both the blocks 2, 3 is generated, no gap is generated between both the blocks 2, 3.
