摘要:
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.

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.
摘要:
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.

A belt for use in a continuously variable transmission comprises an annular hoop of laminated metal elements each having a body and a head joined thereto with a pair of recesses defined therebetween, and a pair of rings inserted respectively in the recesses and each comprising a plurality of laminated metal web-shaped rings. The belt is manufactured by an element production line for producing the elements through a plurality of processes, a ring production line for producing the laminated rings through a plurality of processes parallel to the element production line, and a belt assembly line joined to the element production line and the ring production line, for bundling the elements with the laminated rings thereby to assemble the belt. The elements are inspected for a produced state thereof at a terminal end of the element production line and those elements which are judged as acceptable are sent to the belt assembly line. The laminated rings are inspected for a laminated state thereof at a terminal end of the ring production line and those laminated rings which are judged as acceptable are sent to the belt assembly line. Belts are inspected for an assembled state at the belt assembly line and those belts which are judged as acceptable are delivered as products.
摘要:
A hole-forming machine for forming a through-hole (75) in a workpiece (66) by directing laser light (70) from the exterior of the workpiece into a hollow part (67). 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.

A mobile station (UE) according to the present invention includes: a storage unit (23) configured to store first RAT priority information; a receiving unit (13) configured to receive second RAT priority information and RAT indication information from a radio base station; a camp-on processing unit (12) configured to camp on a cell of a second RAT designated by the second RAT priority information, when a first RAT designated by the first RAT priority information is different from the second RAT, and when the first RAT coincides with a third RAT designated by the RAT indication information; and a display unit (31) configured to show that the mobile station (UE) is camping on the first RAT, when the first RAT is different from the second RAT, and when the first RAT coincides with the third RAT.
摘要:
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. Therefore, the frequency cancellation time expires while the mobile communication terminal is moving from the area B to the area C. The frequency cancellation terminates, so as to be connectable in the area C of the frequency f3.

A mobile communication method according to the present invention includes the steps of: establishing a first radio link between the “LTE-AS” and the eNB in response to the “Service Request” received from the “EMM”; transmitting, from the “UMTS-AS” to the “MM/GMM”, the “reconnect request”, after the completion of the switching process from the mobile communication system of the LTE scheme to the mobile communication system of the UMTS scheme, when the “LTE-AS” detects RLF within a first predetermined period after receiving the switching command instructing performance of the switching process; and not transmitting, from the “MM/GMM” to the “UMTS-AS”, the “Service Request” responding to the “reconnect request”, when the mobile station UE has not performed a packet communication in the mobile communication system of the LTE scheme before a start of the switching process.
