摘要： PROBLEM TO BE SOLVED: To work a small-diameter hole in a printed-wiring board by a laser beam machining operation in such a way that its inner wall roughness, its machining reproducibility and its circularity are good and to work a via hole or the like required for a high-density mounting operation in such a way that it is a small-diameter hole. SOLUTION: In a textile structure, the filament diameter of a glass thread constituting a glass cloth base material is thin at a nominal diameter E or lower, and warps and wefts are woven without any gap. The number of twists of the glass thread is small, and the glass thread is textured and worked. An opening working operation is executed in advance to the glass cloth base material. A glass cloth is black or blackish-brown. A small-diameter hole is worked by a laser beam machining operation.

摘要： PROBLEM TO BE SOLVED: To make it possible to form longitudinal perforations, longitudinal slits, etc., on continuous paper by laser pulses. SOLUTION: The continuous paper 10 is transported by a tractor 22. A rotary encoder 24 generates 240 pulses at each one inch of the paper 10. A pulse generating circuit 30 generates the pulses in the same period as the output pulses of the encoder 24. A controller 28 widens the width of the pulses generated by this pulse generating circuit 30 by as much as the slower speed component when the feed speed of the paper 10 is slower than the target speed. A controller 28 controls the opening and closing of a gate circuit 32 according to paper processing information. The output pulses of the circuit 30 are impressed via a gate circuit 32 on a laser oscillator 34 which oscillates the pulses. The output laser pulses of the laser oscillator 34 are cast to the regulated position in the transverse direction of the paper 10.

摘要： PURPOSE:To make the whole surface sheet of a fibered appearance consisting of an irregular opening hole pattern by forming a plane shape of the upper face opening holes to an amorphous shape by combination of a straight line and a curve, allowing each opening hole to be adjacent to each other through a rib of specific width, and setting an opening hole area of each opening hole to a specific range. CONSTITUTION:A plane shape of the upper face opening hole 6 of a surface sheet 1 is constituted of combination of a straight line and a curve, each opening hole 6 is allowed to be adjacent to each other through a rib 10 of 0.1-3mm, and an area of the opening hole is set to 0.1-25mm . On the other hand, the lower face opening hole 9 is formed obliquely against the lengthwise direction of a liquid conduit tube 8. Also, a peripheral edge 9A of the lower face opening hole 9 is formed in an undulation such as undefinite nap, mustache, saw-tooth. Moreover, the tip of a long tube wall 8B and its vicinity are brought into contact with each other in a shape for embedding them in an absorber 4. In such a way, the fiber-like external appearance can be shown, and a back-flow preventing effect of a liquid conduit tube can be enhanced.

摘要： PURPOSE:To punch a methacrylic resin product or the like with neat cut appearance and economically by changing the shape of a punching blade to adjust a clearance between upper and lower electrodes. CONSTITUTION:Punching metal molds (press upper, lower board) 1, 2 are formed as upper and lower electrodes of a high frequency oscillator, and in these metal molds, a shearing work area in a workpiece 5 is high frequency dielectric-heated and punched. Here by changing the shape of a punching blade (knife edge) 1a, a clearance between the upper and lower electrodes (press upper, lower disk) 1 and 2 is adjusted.

摘要： PURPOSE:To enhance oxygen permeability and to allow the long-time continuous wear of the contact lens by irradiating the contact lens after molding with a polyvalent heavy ion beam to form many pores. CONSTITUTION:The contact lens after molding is irradiated with the polyvalent heavy ion beam and is thereby formed with the many pores. The heavy ion beam to be used is generated from an ion irradiating device such as tandem type ion accelerator and ion species heavier than lithium ions are preferably used as the heavy ions in order to form the finer pores to the contact lens. The charge of the heavy ions are capable of forming the heavy ions of high energy such as pentavalent and heptavalent ions in which many electrons can be taken from the monovalent ions. The pores optimum as the oxygen permeable contact lens are formed by using such polyvalent heavy ion beam. The oxygen permeability is thereby enhanced and the long-term wearing is allowed.

摘要： PURPOSE:To prevent staining by soot by subjecting a material to be worked to working by laser light while said material is held in tight contact with a plate by the suction effect through through-holes thereby making the working stable and removing the generated smoke. CONSTITUTION:The focus of the laser light irradiated through a protective film 7 from each optical part 4 for emission is matched to the bottom of a groove or slightly above the same and while air is sucked through through-holes 5, a film 1 is imposed in the groove. The inside of the through-holes is maintained under a negative pressure and therefore and film 1 is sucked to the groove bottom at least in the circumferential edges of the through-holes so that the film is maintained always at the level coinciding with the focus. The laser light is irradiated from the parts 4 in such a state to pierce the film 1. The generated smoke is sucked and expelled downward through the holes 5 and part of the smoke diffuses by escaping from the spacing between a protective film 7 and a plate 3 or remains in the groove without staining the parts 4.
