IPC: F02B29/04
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an intercooler to effect restoration to a state before freezing even when freezing occurs to the front of the intercooler. SOLUTION: An overhang part 1d overhanging to a position below a conducting duct 2 is formed at the lower tank 1c of an intercooler 1 with the conducting duct 2. A switch valve 7 is arranged at a boundary between the overhang part 1d and a non-overhang part 1e.

Title: Cutting and forming method of fines of metal tube and cutting and forming tool
Inventor: TAKADA MAKOTO
IPC: F28F1/26
Filed: 1979-01-23
Abstract: PURPOSE: To prevent the fins cut and resin from a metal tube from curling and twisting and accurately control the riding direction of the fins by employing a cutting tool having a holding portion formed in parallel with the rake surface of the tool.  
     CONSTITUTION: A cutting tool has a holding portion 10 formed with a cutting edge 4 and a control portion 13. The upper edge 11 of the holding portion 10 is disposed slightly inwardly from the cutting edge. The control portion 13 is formed adjacently at the side edge of one end 9 of the cutting edge 4 in the cutting tool. The holding portion 10 is fixed to a gripper 14. The cutting tool sequentially cuts and rises the top of the projected rib 2 of a metal tube 1 toward its base from its dide surface. Thus, the chip 20 is curled and twisted in its rising direction, and guided through the gap 15 between the holding portion 10 and the rake surface 6 of the cutting edge. Thus, the chip 20 is prevented from curling and twisting. Further, the finally inclined angle of the chip 20 is reduced through the gap 16 formed between the end 9 of the cutting edge 4 and the control portion 13. Accordingly, the rising direction of the fins of the metal tube is accurately controlled.

Filed: 1983-01-17
Abstract: PURPOSE:To improve the reliability for the transmission method of 1:N information by using together with switching both a normal polling mode and a continuous cyclic mode set when a circuit of a down-going system is disconnected or a transmission code error is generated. CONSTITUTION:When a polling signal C1 is detected in a normal mode through the transmitting part of a transmitter 1 of the 1st slave station, a station call signal is applied to a polling mode transmission control part 17 from an S/P converting part 12. A timer 20 detects an abnormality detecting signal in case a circuit break detecting part 18 detects a disconnection or an error detecting part 19 detects an error. Then the output of a cyclic mode transmission control part 21 is sent to a P/S converting part 15. As a result, a synchronizing word is unified with the input information sent from an input part 14 underwent a P/S conversion at the part 15. Thus the 1-frame information is obtained. Then the transmission is carried out continuously to a circuit switching part 103 of a transmitter 100 of a master station which is modulated at a modulating part 16.
