    摘要: A heat transfer tube for an absorber, including a plurality of crest portions and trough portions extending in parallel to each other in an axial direction of the tube and arranged alternately in a circumferential direction of the tube. The ratio d/P of a depth d of each of the trough portions to a pitch P of the crest portions defined as P=.pi.D/n is set in the range of 0.1 to 0.4; the depth d is set in the range of 1.50 to 2.00 mm; the ratio R.sub.2 /d is set in the range of 2.5 to 6.0; the ratio R.sub.1 /R.sub.2 is set larger than 1, where n represents a positive integer, R.sub.1 represents a radius of curvature of an outer top surface of each crest portion, R.sub.2 represents a radius of curvature of an outer bottom surface of each trough portion, and D represents a diameter of a circumscribed circle of the crest portions. Accordingly, the turbulence (Marangoni convection) of the absorbing liquid can be promoted, the wetted area can be widened, and the residence time of the absorbing liquid can be optimized, thereby improving the heat transfer performance.

    摘要: An inverter apparatus includes a basic control section including a main circuit which includes an inverter, and a control unit which controls the main circuit. The inverter apparatus also includes an I/O block which is connected to the basic control section, and is selected from a plurality of different types of I/O blocks. The I/O block includes an input/output interface. The input/output interface includes a signal connection terminal which transmits an input/output signal to/from the control unit. Operation management specifications of the main circuit are fixed independently of operation management specifications of the input/output interface. Operation specifications of the inverter apparatus change depending on the operation management specifications of the input/output interface, and are determined by the type of the I/O block which is connected to the basic control section, such that connecting the different types of I/O blocks to the basic control section causes the inverter apparatus to have different operation specifications.

    摘要: To uniformly cool down armature windings along the circumferential direction of a stator in a generator motor. A generator motor includes a stator 1 fixed to the inner diameter side of a housing 18, a rotor 130 rotatably supported by bearings 5, and armature windings wound around the teeth of a stator core 110. Each of brackets 200 provided via the bearings 5 has a passage 201, 202 through which cooling oil flows and injection holes 204 which communicate with the passage and inject cooling oil at positions opposite to winding ends of the armature windings. Cooling oil is injected toward the winding ends of the armature windings from the injection holes 204 of the brackets 200 arranged on opposite axial sides of a shaft 6. In the flow rate distribution of the oil from the plurality of the injection holes 204, the flow rate of the oil from any of the injection holes 204 is set to be greater as the position of the injection hole 204 is higher above the level of the shaft 6. The arrangement pitch among the injection holes 204 provided on each of the brackets 200 is dense in a vertically upper portion of the bracket 200, and gradually sparser in a portion thereof closer to the level of shaft 6.
