IPC: F28F1/32
Filed: 1985-06-13
Abstract: PURPOSE:To permit to reduce pressure drop with good heat transfer efficiency by a method wherein neighboring heat transfer tubes, penetrating plate fins respectively, are constituted positionally to form a substantially regular triangular form and the one side of the triangle is arranged in parallel to the ventilating direction of the heat exchanger in a condenser for a refrigerating device or the like. CONSTITUTION:A multitude of heat transfer bare tubes 2, through which heat medium flow, are arranged in multiple stages and multiple rows so that neighboring three pieces of heat transfer bare tubes A-C are constituted positionally so as to form a substantially regular triangular form and one side of the triangle is arranged in parallel to the ventilating direction (a) of the heat exchanger while a multitude of plate fins 12, through which the heat transfer bare tubes 2 are penetrating, is provided with proper pitches to form the group of heat transfer tubes for the heat exchanger. A cross but 15 is cut at a place of the plate fin 12, which is corresponding to the penetrating hole 14 for the tube 2, and the roots of the triangular sections 13a, which are equally divided into four segments, are bent to form triangular protuberances 13. According to this method, the pressure drop may be reduced extremely without deteriorating heat transfer efficiency in the group of the tubes and miniaturization of a fan or the like may be realized.

Title: Phase comparator and focus error detector using said comparator
Inventor: MATSUBARA AKIRA
IPC: G02B7/28
Filed: 1988-05-26
Abstract: PURPOSE:To detect a phase difference between focus error signals independently of the duty ratio of output signals from photodetecting elements by applying focus error signals outputted from two photodetecting elements to delay means and comparing respective outputs from the delay means with the output from the other photodetecting element. CONSTITUTION:A signal F is inputted to a /R input of an invert input R-S latch group 5, signals Ia-If successively delayed from a signal G by time tau by delay elements 2a-2f are inputted to a /S input and the leading edge of the signal F is compared with that of the signals La-If. The signal F and the signals Ia-If are also inputted to an R-S latch group 6 and a phase difference corresponding to a focus error is replaced by the number of high outputs out of outputs from the invert input R-S latch groups 5, 6. A shift register 11 receives outputs held in respective latch groups 5, 6 when the latch groups 7, 8 execute latch operation at the time of leading and trailing edges and converts the outputs into signals with pulse widths corresponding to the number of latches outputting high signals from the latch groups 5, 6. Thus, a voltage value corresponding to a focus error can be obtained by removing a high frequency component.
