Patent JP-S55109030-A (JP)
Title: Coding system
Inventor: OKAMURA SHIROU
IPC: H03M1/20
Filed: 1979-02-14
Abstract: PURPOSE: To secure increment of the substantial bit number by performing the coding with the shift of a small amount of quantum given to the quantization steps with every sample.  
     CONSTITUTION: Signal source 10 is switched via switch 15 to coders 11 and 12 featuring the shifted quantization steps each and with every one to several samples. The output of coders 11 and 12 are compounded through compounding unit 16 to obtain transmission output 17. Signal 18 transmitted is decoded by decoders 20 and 21 corresponding to the two shifted quantization levels with switch 19 controlled via marker separator 27, and then added through compounding unit 22. Then the added sample is integrated through integrator 28 to produce composite signal 25. Thus the substantial bit number can be increased without enlarging the band.

IPC: B23H7/04
Filed: 1991-01-16
Abstract: PURPOSE:To reduce the inductance of a current route by arranging the core of a coaxial cable on the route between a work stand and wire guide and also forming the shield of the co-axial cable in a closed loop via the frame of a work tank or a conductive body. CONSTITUTION:The current fed from a power source circuit 1 is passed through the route composed of the shield of a coaxial cable 2, a terminal T1, conductive work stand 11, wire electrode 20, an upper side wire guide 21, the core 31 of a coaxial cable 30, a terminal T2 and the core of the coaxial cable 2. At this time the current in the reverse direction to the current of the core 31 is induced on the shield 32, with a work current being passed to the core 31 of the coaxial cable 30. As a result, the inductance of the coaxial cable 30 becomes low. Also the currents in reverse direction each other are passed on the core and shield of the coaxial cable 2. Moreover the inductance is reduced similarly to the above even on the route where current is passed to the core of the coaxial cable 2 from the lower side wire guide 22.
