Title: Blow-by gas recirculating equipment in internal-combustion engine
Inventor: MIYOSHI TAKEO
IPC: F01M13/02
Filed: 1981-12-11
Abstract: PURPOSE:To prevent fouling in an air cleaner and a carburetor due to oil mist in blow-by gas by directly introducing blow-by gas reversely running through a bypass into an air inlet pipe when the engine is at high load driving. CONSTITUTION:When the engine arrives at its high load driving range, and oversteps A point, blow-by gas generation rate in a crankcase 2 grows to be in the condition that it exceeds the gas flow rate in a PCV path 10. With variation of negative pressure (decrease) in an air inlet pipe 6, a diaphragm 15 makes change-over operation of the valve body 16 of a change-over valve 13, by which the first port 13a is closed simultaneously with opening of the second port 13b  of the change-over valve 13. In result, blow-by gas reversely running through a bypass 12 is directly taken from the second port 13b of the change-over valve 13 via a branch path 14 into the air inlet pipe 6.

Title: Detecting method of defective part of construction
Inventor: ARAI YOUICHI
IPC: G01N25/72
Filed: 1982-11-19
Abstract: PURPOSE:To detect a defective part such as a crack and a water leaking part accurately, efficiently, and economically by measuring the surface temperature distribution of a construction through an infrared temperature measuring device. CONSTITUTION:In general, when the sunshine strickes the surface of a construction, the temperature at the part rises, but if there is a crack on the surface, the discontinuous line of the surface temperature appears along the crack. The surface temperature where water stays is lower than that at any other part. The temperature distribution of the surface of the construction is measured by the infrared temperature measuring device which outputs a heat image or heat photograph and the discontinuous line and low-temperature part of the surface temperture are detected to find defective parts such as the crack and water leaking part of the construction. The infrared temperature measuring device photodetects infrared rays radiated from the measured body by a scanner as a heat video camera and converts them into an electric signal to display a heat image with black and white gradations on cathode-ray tube.
