摘要： There is provided a turbo blower for lasers which is capable of effectively cooling a shaft and bearings thereof. Oil held in a shaft support member is drawn up via an oil inlet port by a centrifugal force generated by rotation of the shaft, and passes through a cooling oil passage extending through the shaft to be discharged from an oil outlet port provided below an upper one of rolling bearings as the bearings. The oil discharged from the outlet port returns via an oil return passage to an oil sump. While passing through the oil return passage, the oil is cooled by a coolant circulating through an coolant passage. Further, part of the oil discharged from the oil outlet port is supplied to the upper one of the bearings for lubrication. On the other hand, part of the oil held within the shaft support member is drawn up along a tapered portion of an oil suction head by the centrifugal force generated by rotation of the oil suction head for lubrication of a corresponding one of the rolling bearings. A large amount of oil flowing through the cooling oil passage can deprive the shaft and the rotor of heat, thereby effectively cooling the bearings as well.

摘要： In a gas laser blower, the lower end opening of the oil passage (14) extends below the liquid level of the oil reservoir (17), so that the internal chamber (18) of housing and the oil passage (14) are separated by the oil within the oil reservoir. Further, a cylindrical guard (24) is disposed around the lower bearing (6) which supports the shaft so that the oil and oil mist scattered from the bearing are caught by the guard (24) and is returned to the oil reservoir.

摘要： In a blower for compulsorily circulating a laser gas for a gas laser apparatus, a shaft (2) of an impeller (1) is fitted with an intermediate member (66) that rotates together therewith, and rings (641, 642) are fitted individually in annular grooves (651, 652) formed on the intermediate member (66). On the other hand, a bearing holder (60) for holding a bearing (5) that supports the shaft (2) is provided with a ring holder (63) having an inner wall kept normally in contact with the respective outer peripheral surfaces of the rings (641, 642). As a result, narrow axial gaps between the rings (641, 642) and the annular grooves (651, 652) prevent gaseous impurities from getting into a gas laser circulation path through a bearing (5).

摘要： A turbo blower is used in combination with a gas laser oscillation device for machining, e.g., cutting off, workpieces. The turbo blower comprises a shaft (2) having an impeller (1) on one end thereof, a pair of bearings (5, 6) on which the shaft (2) is supported, and a motor (3, 4) for rotating the shaft. Heat radiating fins (11) are mounted on the shaft (2) for radiating the heat which is generated by a rotor (3) of the motor, thus preventing the heat from being transmitted to the bearings (5, 6). The heat radiating fins are forcibly cooled by a portion of a laser gas for thereby greatly increasing the heat radiation efficiency. The service life of the grease in the bearings and the bearings themselves is increased, thus reducing an expenditure of labor for grease replenishment and bearing replacement. The bearings are also increased in reliability.

摘要： A hydraulic connector arrangement includes a shaft member, a banjo fitting, a pair of sealing members and a banjo fixing member. The shaft member has a hydraulic passageway and an opening that extends from the hydraulic passageway to an outer surface of the shaft member. The banjo fitting rotatably extends around the shaft member covering the opening. The pair of sealing members are disposed between the shaft member and the banjo member and on opposite sides of the opening. The banjo fixing member is coupled to the shaft member to retain the banjo fitting to the shaft member. Further, the banjo fixing member is dimensioned to allow rotation of the banjo relative to the shaft member and the banjo fixing member.

摘要： A parallel to serial data transfer system includes a CPU for continuously supplying parallel data of plural bytes, a buffer for storing the parallel data transferred from the CPU, a shift resister for loading the parallel data to be converted into serial data, and a selector. The buffer supplies an empty flag to the selector when no data is stored therein, so that the selector supplies a signal to the buffer and the shift resister in order to prohibit a load of parallel data from the buffer to the shift resister.
