Title: Double tube type heat exchanger
Inventor: HIMURO RYOICHI
IPC: F28D7/14
Filed: 1986-01-27
Abstract: PURPOSE:To hold an inner tube at a given position in an outer tube by a method wherein the inner tube, passing liquid to be cooled or to be heated and having a circular section, is fitted into the outer tube, passing refrigerant and having substantially an elliptical section, so that the inner tube is inscribed and contacted closely to said outer tube. CONSTITUTION:An inner tube 2 is contacted closely with an outer tube 1 at the contacting part thereof, therefore, heat flux of liquid to be cooled or heated, which flows through the inside of the inner tube is transferred to refrigerant 4 from the outer peripheral surface of the inner tube 2 as well as the inner peripheral surface of the outer tube 1 contacting with the outer peripheral surface of the inner tube 2. Accordingly, heat transfer area of the side of the refrigerant 4 is increased remarkably and heat transfer characteristics may be improved. On the other hand, the inner tube 2, having a circular section, is arranged so as to be inscribed to the outer tube 1, having an elliptical section, whereby the movement of the inner tube 2 is restricted and the inner tube 2 may be held at a given position surely. Accordingly, the improvement of the heat transfer characteristics may be contrived further by increasing the flow speed of the refrigerant while the improvement of heat transfer coefficient may also be expected by flowing the refrigerant through the space having a crescent section. Further, the double tube type heat exchanger may be manufactured at a low cost.

Abstract: PURPOSE:To permit detection with an excellent S/N as well as discrimination of the shape, size and type of defects, by integrating the flaw detection signal obtained from a self-comparison type detection coil constituted by providing two coil parallel and adjacently to each other. CONSTITUTION:The output waveform of a flaw detection signal in the eddy-current flaw detection by means of a self-comparison type detection coil formed by prociding two coils in parallel andadjacently to each other is obtained as a differnce between the output waveforms of the flaw detection siganls from the two unit detection coils conducting flaw detections for two adjacent parts of objects 1, 2, 3, to be inspected. Therefore, the output waveform is substantially equal to the differential of the flaw detection signal waveform obtained by a unit detection coil. Accordingly, if the flaw detection signal output waveform of the self-comparison type detection coil is integrated, it is possible to obtain waveforms, A-4, B-4, C-4, which are substantially equal to the flaw detection signal output waveforms obtained by employing a unit detection coil, so that it is possible to provide advantages of both a self-comparison type detection coil and a unit detection coil.

Title: Bubble extractor for drink supplying apparatus
Inventor: IMANAGA HIROKAZU
IPC: B67D1/14
Filed: 1990-01-25
Abstract: PURPOSE:To simply extract a predetermined quantity of bubble by providing a bubble extraction button and control means for opening a valve at a predetermined period for each predetermined time to extract the bubble of drink if the button is pressed. CONSTITUTION:Whether it is a selling mode or a setting mode is checked from a switching signal of a mode changeover switch 9, and if a bubble extraction button 7 is pressed in the setting mode, a CPU 5 counts depressions. Then, end of setting is judged by switching to the selling mode, and valve opening time proportional to the depressions of the button 7 is stored in a memory 6. When it becomes the selling mode and a drink extraction button 8 is depressed, a predetermined time relay 11 is energized to open a valve 10, thereby discharging a predetermined quantity of drink. After the drink is discharged, the valve 10 is opened at a predetermined period at each set time while the button 7 is being depressed to discharge a small amount of drink (bubble) at each time. Since an accurate amount of bubble is automatically discharged at a predetermined time interval merely by depressing the button 7, a regular quantity of bubble can be always simply extracted.
