  • VARIABLE COMPRESSION RATIO INTERNAL COMBUSTION ENGINE
    Publication number: 20140290625
    Abstract: It is an object to increase the reliability and durability by minimizing mixing/entry of foreign matter (contaminants) into a speed reducer. The speed reducer is provided for reducing rotation of an actuator of a variable compression ratio mechanism and for transmitting the reduced rotation to a control shaft of the variable compression ratio mechanism. The actuator and the speed reducer are attached to a sidewall of an engine main body with a housing therebetween. An oil filter, which removes contaminants from within lubricating oil, is attached to the housing with an oil-passage-forming body therebetween. A portion of the lubricating oil supplied from the oil filter immediately after having been filter-purified is supplied via a bypass oil passage, formed in the oil-passage-forming body and the housing, into a speed-reducer accommodation chamber of the housing.

  • Welding output control method and arc welding equipment
    Patent number: 8723081
    Abstract: A superimposed voltage waveform with a predetermined cycle and amplitude is superimposed on a commanded voltage waveform for a second predetermined time after a first predetermined time elapses within an arcing period in which an arc is produced. The predetermined cycle of the superimposed voltage waveform is shorter than a short-circuit cycle and longer than a control cycle of a welding power supply unit. This suppresses a growth of a weld droplet by being pushed up toward a consumable electrode and suppresses an excessive growth of the droplet over an entire range from a low current range, characterized by frequent short-circuits, to a medium to high current range where short-circuits are less frequent. The droplet is also smoothly transferred to the weld pool in addition to preventing excessive droplet growth. This reduces the generation of spatter, giving a flatter bead appearance.
