IPC: F25B39/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain for a heat exchanger a distribution header through which the heat-exchanger fluid can be distributed to each of the heating tubes properly and with good heat exchange efficiency. SOLUTION: Through distribution holes 13 which are radially smaller than a main passage 12 connected to a heat exchanger distribution chambers 16 communicate section by section with the main passage 12. Thus a plurality of distribution chambers 14 are disposed, to each of which a plurality of heating tubes 2, constituting heat exchangers, are connected. In this setup a heat- exchanger fluid flows in from a pipe 5, through the main passage 12, and is distributed through distribution holes 13 to the distribution chambers 16.  Since the diameter of the distribution hole 13 is smaller than that of the main passage 12, a passage loss resistance occurs, causing the heat-exchanger fluid to flow into the respective distribution chambers 14 evenly and to be distributed evenly to the plurality of the heating tubes 2 in each of the distribution chambers 14, so that the heat exchangers work efficiently throughout and the heat- exchange capacity can be improved.

Title: Control pulse generating circuit
IPC: H03K5/15
Filed: 1992-03-30
Abstract: PURPOSE:To provide a circuit of high general usefulness by comparing the counted value of a reference clock with the comparison value of a register to output a control pulse. CONSTITUTION:When data is inputted to a data input (DT) 5 synchronously with a data clock (DCK) 6, comparison values of comparing circuits (CMP) 41 to 4n are set to shift registers (SR) 31 to 3n.

The upper limit of the counted value of the counter 2 is determined by a counter clear input (CLR) 7 to set the operation period of the counter 2. CMPs 41 to 4n generate control pulse outputs (OUT) 91 to 9n by results of comparison between the counted value from the counter 2 and comparison values from SRs 31 to 3n. Consequently, the control pulse output is generated in an arbitrary clock position based on the CLR pulse 7.
