Filed: 1990-10-09
Abstract: PURPOSE:To rapidly produce a weld zone having good quality by disposing at least two pieces of condenser lenses in a welding nozzle and constituting the above device in such a manner that one condenser lens operates as a lens for preheating and the other condenser lens as a lens for welding. CONSTITUTION:A laser beam is throttled and arrives on a groove 4 of objects 3 to be welded and forms a spot-like beam (a) when the laser beam passes the condenser lens A. The beam (a) has a high energy density and acts as the beam for welding. A beam (b) of a large circle is formed in the scanning direction of the laser beam on the groove 4 of the objects 3 to be welded when the laser beam passes the condenser lens B. The beam (b) is low in energy density and is wide in range. This beam acts as the beam for preheating i.e., the beam for removing moisture. The underwater welding is executed under a sufficiently dried condition in this way and the weld zone having the good quality is rapidly produced in this way.

Title: Air conditioner
Inventor: MITSUDA TAKESHI
IPC: F25B1/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent a state of exceeding a critical pressure from being generated by a method wherein a degree of opening of a pressure reducing device is controlled by more than a certain specified value when the pressure exceeds a set pressure and then a pressure within a freezing cycle is reduced. SOLUTION: A temperature at the head part of a compressor 1 is detected by a temperature sensor 7 and then inputted to a control section 71 for controlling a degree of opening of an expansion valve. Inputted information is sent to a deviation comparator 72 for comparing the present temperature with a target temperature, and then an amount of operation of an expansion valve stepping motor is calculated at an expansion valve stepping motor operation calculation part 73. Then, it is commanded to an electric expansion valve stepping motor 41. In turn, a pressure detected by a pressure sensor 6 is judged by a pressure judging section 61 whether or not it is higher or lower than a set pressure. In the case that the detected pressure exceeds the set pressure, information is sent to the control section 71 for controlling a degree of opening of an expansion valve. In this case, a command is directly outputted from the control section 71 for controlling a degree of opening of an expansion valve to the expansion valve stepping motor 41. The expansion valve stepping motor 41 opens the valve only by the predetermined number of steps and decreases a pressure of refrigerant.

IPC: F04D29/16
Filed: 1984-12-24
Abstract: PURPOSE:To improve sealing performance by keeping magnetic fluid in a gap between the screw thread tip of a screw pump and the internal surface of its cylindrical cavity by concentrating magnetic flux on the above gap. CONSTITUTION:A spiral screw thread 1a and a land 1b for collecting magnetic flux are formed in projecting shape on the periphery of a rotary shaft 1 made of magnetic material. Magnetic fluid is taken out of the supplying port 8 for the magnetic fluid, and transferred to an exhaust port 5, and then is separated through a separator 10 from working fluid, and fed back to the supplying port 8. The magnetic flux concentrates in a gap between the tip of the screw thread 1a and the internal surface of the cylindrical cavity 2a of an external cylinder 2, and the magnetic fluid is kept in the above gap to move as the rotary shaft 1 rotates. Consequently, leakage out of the gap can be prevented to improve volumetric efficiency.
