A collector 12 which serves as a gas diffusion layer for a fuel cell; i.e., a metal lath MR, is formed by a method consisting of a first step and a second step. In the first step, while an upper blade UH is positioned at a first machining position along the width direction of a stainless steel sheet S, generally hexagonal through holes are formed in the stainless steel sheet S at two positions which are biased from each other by a machining pitch. In the second step, while the upper blade UH is positioned at a second machining position along the width direction of the stainless steel sheet S, generally hexagonal through holes are formed in the stainless steel sheet S at two positions which are biased from each other by the machining pitch. The first step and the second step are alternated repeatedly, thereby forming the metal lath MR having a uniform shape and a predetermined thickness.

An electrode tool for electrochemical machining includes a machining electrode surface (1a). The machining electrode surface (1a) includes a conductive pattern defined by lands (3) and grooves (3a) that are formed by groove machining the electrode surface (1a). The machining electrode surface (1a) is then molded with a hard insulating resin layer (4), and a surface of the hard insulating resin layer (4) is mechanically polished to expose the lands (3) of the conductive pattern. The lands (3) are chemically dissolved to obtain a conductive pattern (14) having a surface that is formed below a resulting insulating resin surface (2), with the height difference between the two surfaces being between 1 and 5 pm. The electrode tool allows precise surface machining of work pieces and can withstand prolonged use.

An apparatus for forming a pattern has a light-modulating unit, a scanner, a pattern data processor, a light modulating controller, a position-error detector, and a correction value calculator. The pattern data processor generates band-pattern data corresponding to each scanning band on the basis of pattern data matching a preceding pattern that is repeatedly and regularly formed on the photo-sensitive material. The position-error detector detects a position-error of the preceding pattern relative to a pattern area. The correction value calculator calculates an alignment correction value in each pattern area on the basis of the position-error, so as to overlay the pattern on the preceding pattern. The pattern data processor corrects the band-pattern data in accordance with the alignment correction value while classifying each exposure data of the band-pattern data into a corresponding pattern area.

In a web processing device, a marking head is disposed so as to oppose an X-ray film which is trained about a print roller which is at an upstream side of slitting blades. Within a scanning range of a laser beam of a marking head, two printing regions are disposed with a non-printing region therebetween. The non-printing region is disposed so as to oppose a cutting line which is cut by the slitting blades. Before cutting the X-ray film, the web processing device forms marking patterns on both sides of the cutting line.

The invention relates to a method for producing a heat exchanger, wherein at least one microchannel, placed within a plate having an upper face and a lower face and precisely arranged between said upper face and lower face is obtained by making a groove on the upper face of the plate, said groove extending between an open extremity facing on the upper face and a blind extremity placed inside the plate, and machining the blind extremity of the groove to create a volume of a suitable size to house a tube inserted in the microchannel, said tube being fixed inside the microchannel by generating an interference between the tube and the microchannel. The invention relates also to a heat exchanger obtained by such method.

A violin thumb pad that facilitates the optimal positioning of violin relative to the player's thumb supporting the violin neck, for teaching purpose and for increased comfort and reduced physical stress, is introduced. Assuming the violin player uses left hand to play the violin finger board, and used right hand to hold the bow, the violin thumb pad forces the left thumb and palm to turn towards the player so the player's fingers are inline with the violin string naturally. The violin thumb pad also forces the left thumb and to be comfortably straight. And it forces the left elbow to stay close with the player's body. The violin thumb pad also makes it easier to place the violin neck between the thumb and index finger and not letting the violin neck drop to the bottom of the thumb. The violin thumb pad comprises an elongated pad that has one side conformable to the thumb and one side conformable to the violin neck, and at least one harnesses or loops that fastens the pad to the thumb.
