  • Patent number: 8394461
    Abstract: A powder-containing oil-based lubricant for die contains 60 to 99% by mass of an oil-based lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The powder-containing oil-based lubricant may be applied to a die by electrostatic spraying. The electrostatic spray apparatus includes a device that imparts static electricity to the powder-containing oil-based lubricant and an electrostatic spray gun installed on a multi-axis robot.

  • Publication number: 20110250363
    Abstract: The invention relates to an oil type lubricant, which is applied to a die to be used in high-pressure die casting, gravity die casting, low-pressure die casting and forging and can prevent soldering, particularly at high temperature parts and under a heavy load, to a spray method of applying the oil type lubricant and a spray apparatus for applying the oil type lubricant. The powder-containing oil type lubricant for die contains 60 to 99% by mass of an oil type lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The electrostatic spray method includes applying the powder-containing oil type lubricant to a die by electrostatic spraying. The electrostatic spray apparatus includes a static electricity imparting device that imparts static electricity to the powder-containing oil type lubricant and an electrostatic spray gun installed on a multi-axle robot.

  • Patent number: 4174892
    Abstract: A method and apparatus for automatically focusing a camera is described in which the camera has a stationary optical path and a scanning optical path for developing focusing signals. The scanning optical path is caused to undergo a range-finding reciprocation in which it reciprocates between first and second limit positions, as between the minimum lens focusing position and the infinite lens focusing position. Two focusing signals are generated during the range-finding reciprocation and the interval between the focusing signals is used to derive the distance to the subject. The lens is then positioned in accordance with the derived distance to the subject.

  • Patent number: 4156563
    Abstract: Disclosed is an improvement in an automatic focusing system for use with an optical instrument having a focusable objective which is adjustable in response to optical and electronic components of the system for determining object distance of a remote subject by comparing images of scanning and reference optical systems. The scanner of the optical system is driven oscillatably across an angle to detect a subject between infinity and the minimum focus condition of the objective lens. The present invention relates to improvements in an automatic focusing system for use with an optical instrument having a focusable objective. More particularly, the improvement relates to driving the focusing system to a preset fixed focus setting when the system senses difficult conditions for focus detection as those having low contrast or complex subject matter.
