Abstract: PURPOSE: To transfer fibers in a uniform distribution state onto a collecting surface by stripping the fibers on a cylinder by a supply air stream between a card cylinder and a worker. CONSTITUTION: In the production of a nonwoven fabric, stock fibers are supplied to the card cylinder 1 and are uniformly opened via the worker 5. The fibers are stripped from the cylinder 1 by the supply air stream 6 passing a supply air passage 12 formed in the narrowest spacing between the cylinder 1 and the worker 5 and are sent to a suction passage 3. The supply air stream 6 comprising partial steams 10 and 11 and the supply air stream 7 passing the supply air passage 6 between the cylinder 1 and a cylinder cover 9 on the retreat side thereof act on the suction passage 3. The fibers entrained to the worker 5 by the supply air stream 18 passing the supply air passage 16 between the worker 5 and the worker cover 17 are returned to the suction passage 3.  Further, the fibers passing the suction passage 3 are uniformly transferred onto the collecting surface 2 by the negative pressure of a suction box 4 divided to plural suction areas 4a.

Abstract: PURPOSE:To improve the image quality of an obtained image by applying multi-level coding processing or binary coding processing to the image in the unit of blocks so as to apply coding and compression to an original image efficiently in which a character image and a photographic image are in existence in mixture. CONSTITUTION:A multi-level scanner 4 reads an original image by one page and the obtained multi-level image data are stored tentatively in a memory 2. The image data are extracted from a read page buffer and a prediction error by one block is calculated and its mean value DA and a maximum value DM are calculated. Whether or not the mean value DA is a prescribed threshold level R1 or below is checked. When the man value DA indicates YES, whether or not the maximum value DM is a prescribed threshold level R2 or not is checked. When the result indicates YES, the block is a block not forming code data and a flag FN is set to a code buffer. When NO, code data are generated as to the block. When the maximum value DM is larger than a prescribed threshold level R3(>R2), image data are code-compressed by a binary coding decoding section 8. When smaller, the image data are coded and compressed by a multi-level coding decoding section 107.

Abstract: PURPOSE:To prevent the occurrence of misoperation or wrong confirmation of an operation-checked result at the time of inspecting a semiconductor device. CONSTITUTION:Standard input-output patterns prepared by digitizing input and output signals to and from a standard LSI 3a are stored in a memory section 5. When an LSI inspection is performed, a driver section 6 converts the standard input pattern stored in the section 5 into a signal similar to the signal to be inputted to the standard LSI 3a and inputs the converted input signal to an LSI 3b to be inspected. As a result, the LSI 3b starts to operate and outputs a signal. A digital converting section 4 converts the output signal of the LSI 3b into a digital signal and prepares an output pattern. Then a decision circuit 8 decide the propriety of the LSI 3b to be inspected by comparing the standard output pattern stored in the memory section 5 with the output pattern of the LSI 3b.

Filed: 1983-08-30
Abstract: PURPOSE:To remove the circuit on a printed board without damages by a method wherein the IC is attracted by magnetic force while the solder at IC terminals fixed to other conductors is heated. CONSTITUTION:A permanent magnet 1 and the IC3 are adsorbed to each other by magnetic force, and are then pulled up by the force of the degree that the magnet 1 is just about to separate from the IC3, while hot windows 11 and 12 are blown to the solders 6.
