Title: Heat exchanger
Inventor: HATADA TOSHIO
IPC: F28F1/32
Filed: 1981-11-27
Abstract: PURPOSE: To improve the heat-exchange efficiency by a method wherein a large number of nicks are cut along the direction opposite to that of the flow of heat- exchanging fluid passing between fins and said nicks are raised up to form chevron segments so as to give disturbance to the flow of the fluid at the finned part of the heat exchanger.  
     CONSTITUTION: A large number of nicks 13 are cut parallel to the direction normal to that of the flow of the fluid passing between the fins (or nearly to the direction of the row of pipes) and said respective nicked segments 14 are bent at the center along the direction of width between nicks in theform of chevron to the base plate of fins in the form of arch bridge in order to change the heights of each of the chevron segments 16', 16" and 16''' so as to provided positional lags toward the flow of liquid at the edges 13', 13" and 13''' of the adjoining chevron segmentgs. Owing to the existence of said chevron segments 16', 16" and 16''', the flow of the heat-exchanged fluid flowing along the fin surfaces is disturbed remarkably and complicatedly and consequently the formation of temperature boundary layer is prevented, resulting in remarkably improving the heat -exchange efficiency.

Filed: 1991-07-30
Abstract: PURPOSE:To compensate a non-linear distortion generated at the previous stage of an A/D conversion circuit even at the time of using an amplifier whose distortion is large at the previous stage by adding an arbitrary order non-linear distortion coefficient of an arbitrary size capable of being adjusted at an outside, to a reference voltage. CONSTITUTION:Resistance elements R-n-Rn have the same resistance values, the resistances are pressure-divided between high-order side and low-order side reference voltages VRH and VRL, and the (2n-1) pieces of reference voltages are generated at each node N-n+1-Nn-1. The reference voltage of each node is compared with the voltage of a signal input terminal 4 by voltage comparator circuits C-n+1-Cn-1 and when the input voltage is higher, a high-order voltage is outputted, and when the input voltage is lower, the low-order voltage is outputted. When the output of the amplifier circuit at the previous stage is increased, and made close to a saturation, the amplitude is restricted, and an output waveform is distorted. At that time, each current source 3(J-n+1-J1, and J1-Jn-1) is varied, and the reference voltage of each node (N-n+1-Nn-1) of a reference voltage generating circuit 15 is unequally distorted corresponding to an output, so that distorted components can be canceled.
