Title: Manufacture of helical fin
Inventor: NOGAMI SHINPEI
IPC: F28F1/36
Filed: 1982-07-09
Abstract: PURPOSE:To form splits and both projections and waves having different thicknesses respectively in the surface of a fin, by forming the prescribed recessed grooves in the surface of rolling rolls, in a manufacturing method of a fin to be wound around a heat transfer pipe of a heat exchanger by rolling the fin between rolls. CONSTITUTION:A helical fin 3 is obtained by continuously feeding and passing a fin material through the contacting surface between a large and a small rolling rolls 1, 2 positioned to have a prescribed opening angle between their roll axes. Here, recessed grooves 4 are formed in the rolling surface of at least one side of the rolls 1 and 2. One end of the groove 4 is formed at the position extended further from the passing position of the outer periphery of the fin of the rolling surface of the roll, and the other end is formed at the position short to the passing position of the inner periphery of the fin, so that the projecting surface of the fin is surely produced from the outer peripheral tip of the fin properly to the middle part of it toward the inner periphery side. Thus, the rolling force exerting on the surface of the fin positioned on the groove 4 is smaller than that of the other part, and the elongation of the fin at said position is also smaller, accordingly a fin as shown by the figure is obtained.

Title: Automatic focus adjusting device
Inventor: UTAGAWA TAKESHI
IPC: G03B13/36
Filed: 1994-05-09
Abstract: PURPOSE:To obtain a device with a body tracking function which employs a driving system developing from intermittent driving by providing a 1st driving mode for driving depending upon a defocusing quantity and a 2nd driving mode for driving depending upon a quantity for correcting the influence of the movement of an image formation plane. CONSTITUTION:When the object body moves, a state equivalent to a state wherein an object body is at a stop is entered by controlling a lens driving means in the 2nd driving mode so that the optical system for focus matching of an image formation optical system is moved at a speed based upon the speed of image plane movement accompanying the movement of the object body at all times. The defocusing quantity if found shows the separation quantity between nearly parallel two tracks, so the discrepancy between both the tracks is eliminated in the 1st driving mode for driving depending principally on the defocusing quantity to enable accurate tracking. Consequently, a focusing state is entered with the defocusing quantity which is detected intermittently, so continuous tracking is easily performed and smooth motion is obtained.
