A laser transmitter assembly of the present invention is configured for placement within a firing chamber of a user firearm and to have minimal interference with a firearm extractor during charging of the firearm. The laser assembly emits a beam of laser light toward a firearm laser training system
A laser transmitter assembly of the present invention is configured for placement within a firing chamber of a user firearm and to have minimal interference with a firearm extractor during charging of the firearm. The laser assembly emits a beam of laser light toward a firearm laser training system target in response to actuation of the firearm trigger to simulate firearm operation. Further, the laser assembly is manufactured to project a concentric laser beam relative to the firearm barrel, thereby enabling use without having to align the assembly with the firearm bore sight.

An airflow assembly which creates an axial airflow through at least one heat exchanger, said assembly comprising, (i) a fan according to any of claims 1-6; and (ii) a shroud having a peripheral wall extending from said fan to said heat exchanger to guide the flow of air through said heat exchanger. 8. The airflow assembly of claim 7 wherein said assembly is adapted for connection to a heat exchanger positioned downstream from said fan, and said peripheral wall extends downstream of said fan to provide a discharge for air flowing through said heat exchanger. 9. An airflow assembly according to claim 7 wherein said assembly is adapted for use with an automotive engine cooling heat exchanger. 10. A method of assembling a cooling assembly comprising, (1) providing an airflow assembly according to claim 7, and a heat exchanger, and (ii) assembling said airflow assembly to said heat exchanger. 11. The airflow assembly of claim 7 wherein said assembly is adapted for connection to a heat exchanger positioned upstream from said fan, and said peripheral wall extends upstream of said fan to provide an intake for air flowing from said heat exchanger, said opening being a discharge opening. 12. An airflow assembly according to claim 11 wherein: (i) the assembly creates an axial airflow through at least one additional heat exchangers located downstream of said assembly; the shroud has a peripheral wall extending downstream of said fan to provide a discharge for air flowing through said additional heat exchanger. 13. The airflow assembly of claim 7, in which said shroud further comprises a plenum surface to prevent the recirculation of air from the high pressure exhaust side of the fan to the low pressure region immediately upstream of the fan, with an opening of reduced periphery which closely encloses said fan at the outer edge of said band. 14. The airflow assembly of claim 13 further comprising said heat exchanger. 15. A method of assembling an airflow assembly, comprising, providing: (i) a fan according to any of claims 1-6; and (ii) a shroud having a peripheral wall extending from said fan to said heat exchanger to guide the flow of air through said heat exchanger, said shroud further having a funnel-like plenum surface, to prevent the recirculation of air from the high pressure exhaust side of the fan to the low pressure region immediately upstream of the fan, with an opening of reduced peripher y which closely encloses said fan at the outer edge of said band; and assembling said fan and said shroud to produce said airflow assembly. on, a Y-axis moving block installed on the X-axis moving block and moved in a Y-axis direction that is perpendicular to the X-axis direction, a nozzle holder installed on the Y-axis moving block so as to be movable upward and downward, a Z-axis guide rail installed on the X-axis moving block and has an inclined part that rises from a die pick-up position side toward a die bonding position side, a Z-axis moving plate moved upward and downward along the Z-axis guide rail and is connected to the nozzle holder, and a suction chucking nozzle that holds the dies by vacuum suction and is installed so as to be moved upward and downward on the nozzle holder and together with the nozzle holder.
