摘要： A refrigerant tube for use in heat exchangers comprises a flat aluminum tube having parallel refrigerant passages in its interior and comprising flat upper and lower walls and a plurality of reinforcing walls connected between the upper and lower walls, extending longitudinally of the tube and spaced apart from one another by a predetermined distance. The reinforcing walls are each formed with communication holes for causing the parallel refrigerant passages to communicate with one anther therethrough. The flat aluminum tube is prepared from upper and lower two aluminum sheets by bending opposite side edges of the lower aluminum sheet to a raised form and joining the bent edges to the respective side edges of the upper aluminum sheet which is flat so as to form a hollow portion. The reinforcing walls are formed by joining to the inner surface of the upper wall ridges projecting inward from the lower wall. The communication holes are formed by cutouts formed in the edges of the ridges at a predetermined spacing and having their openings closed with the upper wall.

摘要： A power supply for an electroerosion machine having a switching element which controls the machining current in the gap. The value of the current is compared with a predetermined voltage and the signal generated based on this comparation is provided to a logic gate, advantageously an "AND" gate, whose output signal is applied to the control electrode of the switching element. Electrode consumption is reduced by using a generally step-type current waveform signal. Machining current during the discharge period may also be controlled to more closely approximate a square wave so that shifting to a faster machining rate can be easily accomplished by accepting some sacrifice in electrode consuption. Preferably, two or more switching and gating devices are used to permit gap current to flow intermittently during the entire discharge period.

摘要： A method of and apparatus for supplying power during EDMing in which reverse polarity pulses are used to inhibit electrolytic activity. A main voltage pulse of a certain polarity and an auxiliary voltage pulse, preceding the main voltage pulse of the same or reverse polarity, are applied across a machining gap during the on time of a main gate signal and until a discharge is detected. The ratio of the number of auxiliary voltage pulses of regular polarity to those of reverse polarity is set to a desired value depending upon machining conditions, to thereby obtain a good compromise between the conflicting requirements of achieving a high machining rate, while inhibiting undesirable electrolytic activity.

摘要： A motor control apparatus for an electric power steering system having a torsion torque sensor for detecting a torsion torque of the steering system of a vehicle, a command signal generating unit for generating a command signal in accordance with the torsion torque detected by the torque sensor, and a motor control unit for driving and controlling a motor of the electric power steering system in accordance with the command signal. The improvement of this invention is to assist steering force within the steering wheel correcting range. A steering speed detecting unit is provided for detecting the steering speed. The output signal from the steering speed range detecting unit is supplied to the steering wheel correction command unit which generates an assist correction signal. The assist correction signal has a characteristic that the absolute value thereof takes a predetermined value when a small steering angle range is detected. The output from the steering wheel correction command unit is supplied to the motor control unit to regulate the command signal. Such regulation may be effected so as to decrease the command signal as the vehicle speed increases. Alternatively, the command signal may be regulated in accordance with the correction factor signal.
