Title: Production of hollow member for automobile stracture made of aluminum alloy
Inventor: UENO SEIZO
IPC: B21D26/033
Filed: 1994-12-15
Abstract: PURPOSE: To obtain a hollow member for automobile stractural use made of an Al alloy having different cross-sectional shapes in the longitudinal direction by forming a hollow extruded shape in a state where the outer periphery is bent and extending the outer periphery by executing partial bulging. CONSTITUTION: The hollow extruded material is formed into the cross-sectional shape of an extruded tube part 12 and T6 treatment is executed. At the time of bulging, the bended parts 12a of the outer periphery of the extruded tube where is gently inward bent are formed on the outer peripheral surface so that the thickness in the elongated part 14a of the outer periphery of the expanded tube part 14 is smoothly elongated without thinning. The length of the outer periphery of the member is decided by taking the cross-sectional area in a largest part of the cross-sectional size into consideration and the bending angle and peripheral length in the bended part 12a of the outer periphery of the extruded tube is decided by taking the peripheral length after bulging into consideration.  In the above-mentioned manner, the hollow member 10 for automobile structure made of the Al alloy integrally provided with the extruded tube part 12 and expanded tube part 14 and having partially different cross-sectional shape in the longitudinal direction is obtained.

Title: Gas combustion device
Inventor: YAGI KAZUO
IPC: F24H9/20
Filed: 1993-12-13
Abstract: PURPOSE:To improve a reliability of an output signal obtained from a sensor and further to improve a durability of the sensor by a method wherein a gas discharging passage is contacted with a side wall of a boiler while being kept at a heat conduction state and at the same time the sensor is arranged at the contacted part within the gas discharging passage or its downstream side. CONSTITUTION:Combustion discharged gas generated at a gas burner 3 flows from a main heat exchanging part 1a through a sub-heat exchanging part 1b to a gas discharging passage 23, and then the gas is discharged out of a gas combustion device. Then, a state in the gas discharging passage 21 is monitored by the sensor for the combustion discharged gas. In this case, since the discharging gas passage 21 arranged at a downstream side of a boiler 6 storing a heat exchanger 1 therein is contacted with a side wall of the boiler 6 under its heat conduction state, the contacted part at the gas discharging passage 21. shows a high increased temperature due to a heat conduction of generated heat amount at a gas burner 3. Accordingly, the combustion discharged gas flowing within the discharged gas passage 21 is heated at the contacted part so as to reduce a relative humidity. With such an arrangement as above, since the combustion discharged gas of low humidity contacts with the sensor, drain hardly contacts with the sensor.
