摘要： PROBLEM TO BE SOLVED: To manufacture a heat exchanger with an improved productivity wherein a corrugated shape fin is fastened almost vertically against an axial direction of a straight pipe part of a meandering heat conducting pipe. SOLUTION: By this device, a fin material 2a is nipped between bending dies 5a, 6a being bound with a parallel link 19 and, is bent in zigzag so as to perform a corrugated molding. The bending dies 5a, 6a are used as the positioning jigs against the pipe 9 for inserting the pipe 9 into a fin 1a and then for being caulked. Thus, the fin material 2 can be molded fast without being cut and, irregularities such as a slit can be formed on the fin side face. A heat exchanger having improved heat exchanging performance can thus be obtained.

摘要： PROBLEM TO BE SOLVED: To efficiently exhaust remaining gas by installing plural holes communicating with the inner space of a panel in a front plate or a back plate, supplying gas whose dew point at a pressure higher than the atmospheric pressure is adjusted to a specified temperature or lower from one hole, releasing the gas from another hole to the open air to clean a panel, and exhausting the remaining gas in the panel from the hole through which the gas is supplied. SOLUTION: This plasma display panel 20 which is positioned and assembled is temporarily fixed with a clip 11. A connecting head 12 is connected to the plasma display panel 20 through a glass tube 8, and also connected to a vacuum exhausting device 14, a cleaning gas introducing device 15, and a discharge gas introducing device 17 through selector valves 19a, 19b, 19c. A furnace 50 is a heating means for accelerating exhaust of the remaining gas or welding of frit, and a heat exchanger 18 makes the temperature of the cleaning gas sent from the cleaning gas introducing device 15 and that of the furnace 50 uniform, and prevents generation of thermal stress caused by temperature difference between the outside and the inside of the plasma display panel.

摘要： PURPOSE:To reduce the number of defective products without much labor, regarding an air compression device manufactured through a plurality of processes. CONSTITUTION:Loaded torque generated via the turn of an eccentric camshaft 23 is measured at an alignment inspection process 6b, and sent to a line control computer 10 as inspection data 11a. Also, the judgement criterion memory section of the computer 10 stores data regarding a correlation between a loaded torque waveform and a defect cause, and a relationship between the defect cause and a process to generate the cause and the content of an improvement at the process. Also, a defect cause determination section 103 defines the defect cause on the basis of the correlation stored in the judgement criterion memory section. An improvement content determination section 104 defines a process to generate the defect cause, and the content of the improvement of the process, on the basis of the relationship saved in the judgment criterion memory section and the defined defect cause.

摘要： PROBLEM TO BE SOLVED: To simultaneously braze plural pipes different in thickness and shape in multi point by picking up joining members heated by a burner and a brazing filler metal attached to these members by an image pickup means, detecting the wetting-spread of the brazing from the image, heating the members for a prescribed time and stopping the heating. SOLUTION: Three points in the deformed pipe 2 with a brazing device 100 and four points in the returned pipes 3, 4 with a brazing device 101, are brazed. Burners 9 are descended to the positions which heat brazing objects, with a vertical moving mechanism 8 which can vertically be moved to each burner and the pipes are heated by spouting oxygen-propane flame 10 from this tip part, and the burner is retracted so as not to heat the pipe at the time of ascending. The brazing filler metal is melted with this heating and wetted and spread. Since this wetting spread surface can clearly be observed by using a filter 11 transmitting a light having 600-750 mm wave length, the detection is executed with a CCD camera 12 attached with the filter 11. Thereafter, the pipe is heated for the prescribed time with a heating control means and stopped.

摘要： PROBLEM TO BE SOLVED: To make the work for a plate type by-pass circuit easier and to equalize the phase status of refrigerant by joining plates formed with H shape recessed parts corresponding to a pair of refrigerant flow paths arranged in parallel and a by-pass flow path crossing squarely the flow path with the recessed parts facing each other. SOLUTION: Refrigerant flow paths 11b, a by-pass flow path 11c connecting between the refrigerant flow paths 11b and piping connecting parts 11d are formed with plates 11a formed with H shape recessed parts corresponding to a pair of the refrigerant flow paths 11b arranged in parallel and the by-pass flow path 11c crossing the flow paths 11b squarely. The plate type by-pass circuit 11 is formed by joining the pair of plates 11a by pressing with a predetermined pressure the pair of the plates 11a with solder between them and melting the solder heating the pair of plates 11a in the environment of inert gas. At that time, parts of the solder are arranged to positions corresponding to the refrigerant flow paths 11b and the by-pass flow path 11c.

摘要： PROBLEM TO BE SOLVED: To suppress the defective brazing by re-starting the feed of the brazing filler metal by a control means when the brazing filler metal is insufficient for a parts to be joined. SOLUTION: An object 2 to be joined is heated by a heating device 3, and a brazing filler metal is fed between parts to be joined (pipes) 2a, 2b. The image is pined up by vision cameras 1a, 1b, and the picked-up image is stored in an image storage device 7. The position of the pipes 2a, 2b is detected by a position recognition part l based on the image. Then, a heating device 3 is turned on by a control part 6 to start the heating. When the pre-heating is completed, the feed of the brazing filler metal 5 is started from a brazing filler metal feed nozzle 4. The shape of the brazing filler metal formed on the joined parts 2a, 2b is recognized based on the image data. A brazing filler metal shortage judgment part 10 judges whether or not the brazing filler metal is in short. When it is judged that the brazing filler metal is in short, the feed of the brazing filler metal is re-started by the control means 6. The high-reliable brazing can be performed thereby.

摘要： PURPOSE:To perform accurate centering so as to ensure smooth rotation of a rotary body without lowering the compression efficiency of a rotary type compressor. CONSTITUTION:A rotary body is temporarily mounted on a non-rotary body and load torque when the rotary body is rotated is measured by a torque sensor 24. From the load torque, a clearance between the outer peripheral surface of the rotary body and the inner peripheral surface of the non-rotary body in which the rotary body is rotated is determined by a clearance estimator. When the clearance is outside a clearance allowance range specified by upper and lower limit values, an XY table 30 is operated by an assembly position controller and the non-rotary body is moved relatively with the rotary body so that the clearance is held within an allowance range. Thereafter, the rotary body is completely mounted on the non-rotary body.
