Abstract: PURPOSE:To reduce operational resistance during conveyance for facilitating a cleaning operation by disposing two rotary brushes so that the respective axes make an acute angle at the distal ends. CONSTITUTION:Air sucked from suction chambers 17a, 17b flows therefrom through a communicating hole 22 to a connecting port 19, a suction port 21 and a dust collecting case 20.

Title: Eddy current flaw-detecting device
Inventor: WATANABE HIROYUKI
IPC: G01N27/90
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce the scattering in flaw detection sensitivity by arranging a plurality of pairs of an excitation coil and a detection coil on the end face of a core body that opposes a body whose flaw is to be detected and making different the polarities of adjacent excitation coils each other. SOLUTION: Three excitation coils 2 are provided in three rows while shifting each position in the longitudinal direction on a lower surface that opposes the steel plate of a ferrite core body 1 in a rectangular block shape. Detection coils 3A-3C consisting of a pair of coil parts 31 and 32 are provided directly below the excitation coils 2. The excitation coils 2 and the detection coils 3A-3C are formed and laminated spirally on an insulation film substrate by printed wiring and the polarities of the adjacent excitation coils 2 differ. As a result, an eddy current being generated in a steel plate due to the excitation coils 2 draws eddies in opposite directions directly below each excitation coil 2. Therefore, a flaw detection sensitivity becomes nearly equal in any of the detection coils 3A-3C, thus eliminating the scattering in the flaw detection sensitivity.

Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To attain high compressibility of a compression device by dividing an original word having plural bits into most and least significant bits, compressing the least significant bits by a loss compressor and combining the most significant bits with the compressed least significant bit. SOLUTION: When a single code word 31, for example, is divided into three most significant bits(MSBs) 32 and five least significant bits(LSBs) 33, only the bits 33 are compressed. Then bits 0 to 4 are sent to a loss compressor (hierarchical vector quantization(HVQ) encoder) 35 and bits 5 to 7 are not sent anywhere. Both channels are compressed by means of an LZ encoder 34 having no loss and outputted to a decoder. Even under such conditions, both channels are restored by an LZ decoder. Meanwhile, only the bits 33 are decoded by an HVQ decoder. Then two parts which are generated as the results undergo the exclusive OR and are inputted to a coding reference table.
