Abstract: A first laser working method includes a step of irradiating the metallic work held by a rotation holding mechanism, with a nanosecond laser beam from a first laser oscillation mechanism, to form a through hole, and a step of irradiating, when the metallic work is rotated under the action of the rotation holding mechanism, the inner wall of the through hole with a picosecond laser beam from a second laser oscillation mechanism, thereby to finish the same. While forming the through hole, metal vapor is sucked from the outside of the metallic work. Then, the gas is fed from the outside of the metallic work, and the inside of the metallic work is suctioned. In a second laser working method, when a lower hole made through is radially enlarged, the exit side of the lower hole is kept lower in pressure than the laser incident (or entrance) side.

The machine includes a vibrating mechanism (56) for causing vibration in a filler (65) which fills the hollow part of the workpiece (66) and which is not melted by the laser light, the vibrating mechanism being disposed so as to be in contact with the filler.

Abstract: A mobile communication terminal holds a frequency cancellation list that is information related to cells that cannot be connected, and controls execution/non-execution (frequency cancellation) of the cell search according to the content of the cancellation list. In a case where a frequency is not assigned in a unified manner (when a frequency is assigned to different communication providers in some cells), a frequency cancellation time is set shorter than a case where the frequency is assigned in a unified manner. For example, a frequency f3 is rejected in a cell represented by “another” surrounded by a broken line when the mobile communication terminal moves from an area A to an area B. When the mobile communication terminal further moves to an area C, the frequency cancellation process initiated in the area B terminates. This is because a short frequency cancellation time is set.

Preferably, the terminal insertion bore has a membrane, which includes a substantially curved groove and a substantially curved lamella. Preferably, the terminal insertion bore has a membrane which includes a lamella, the lamella being oriented in a direction coincident with a diagonal line of a rectangular cross-section of a terminal so that corners of the terminal hit opposite ends of the lamella.

Abstract: A perforation method and an perforation apparatus in which a hollow member of a fuel injection nozzle is filled with a filler such as a zirconia ball, and a laser light is applied to the hollow member to form an injection hole while vibrating the zirconia ball using an ultrasonic vibrator. After the injection hole is formed, the laser light is introduced through the injection hole to the inside of the fuel injection nozzle, and thereby is applied to the vibrated zirconia ball.

Abstract: A method of laser machining a small hole with high machining precision in a machined object. The method includes the steps of emitting a laser beam with a fixed optical axis onto a machined object while the machined object is rotated. When the optical axis of the laser beam is fixed in place, the edges of the small hole to be machined are irradiated and the small hole becomes essentially circular even if the cross-sectional shape at the focus of the laser beam is not circular. When the small hole is formed completely through the machined object, a plume is suctioned for removal from a portion of the machined object on a side opposite from the machined hole.

Abstract: The resin molding machine is capable of cleaning a resin molding die while performing a molding action without stopping the molding action and capable of securely removing contaminations from the resin molding die. The resin molding machine comprises: a press unit including a resin molding die; and a cleaning unit for cleaning a molding face of the resin molding die. The cleaning unit has an energy ray irradiation section, which irradiates an energy ray to the molding face of the resin molding die so as to easily peel off a contamination, which has been stuck on the molding face during a molding action, from the molding face. The contamination is stuck onto resin of a molded product when the product is resin-molded, so that the molded product is released from the resin molding die together with the contamination.
