Abstract: PURPOSE:To prevent that the expensive vapor of the inside of a soldering device is leaked out to the external part by providing a main cooling part and sub- cooling part on the carry-in port part and carry-out port part of the part to be soldered in a vapor type soldering device. CONSTITUTION:A vapor phase 25 is formed by evaporating with heating by a heater 24 by inputting a fluorine inert solvent liquid 23 to the lower part of a vapor tank 21 in a vapor soldering device. The body 32 to be soldered is transferred from carry-in port part 31 therein and subjected to a reflow soldering with the latent heat of evaporation owned by the vapor phase 25 and carried out to the external part from the carry-out port part 34. In this device, the main cooling part 34 and sub cooling part 41 to prevent the leakage to the external part of the vapor phase 25 are provided in the inner part of the carry-in port part 31 and carry-out port part 33. In this way the bottom face of the carry-in port part and carry-out port part is cooled to prevent the leakage outside the vapor tank 21 from the carry-in port part 31 and carry-out port part 33 with the re-evaporation of the condensate of the vapor on the bottom face.

Filed: 1982-05-18
Abstract: PURPOSE:To prevent difficulty of starting an engine even if a long term is passed after use and left as it is, by making the float chamber of a carburetor empty by discharging fuel in the float chamber automatically after the engine is stopped. CONSTITUTION:Prior to stopping to an engine, a fuel cock 6 and an airpassage cock 4 are interlocked with each other by a link 12. In case that the fuel cock 6 is closed, the air-passage cock 4 is opened, so that an air sump 1a of a fuel tank 1 and an intake passage extended to the engine are communicated with each other via an air passage 3. Resultantly, pressure in the fuel tank 1 is made negative by the suction vacuum of the engine, so that residual fuel in a float chamber 8 of a carburetor is drawn up into the fuel tank 1 via a return pipe 10 which is extended from the bottom of the float chamber 8 to an upper portion of the fuel tank 1. In case that the fuel cock 6 is opened, on the other hand, the fuel tank 1 is communicated with an atmospheric port 4a, whereby it is enabled to automatically extract gasoline in the float chamber completely when the engine is stopped.

Title: Treatment of dust in iron manufacturing
Inventor: MIZUTA TAMOTSU
IPC: C22B7/02
Filed: 1982-05-18
Abstract: PURPOSE:To improve dehydration efficiency and to prevent the scale formation in a filtrate by mixing the slurry of blast furnace dust with the slurry of the dust from an unburned gas recovery type converter, and dehydrating the same after holding the dust mixture for a specific time. CONSTITUTION:Converter dust and the dust from an unburned gas recovery type converter are made respectively into slurries, both of which are then mixed. The Ca(HCO3) in the slurry of the converter dust and the Ca(OH)2 in the slurry of the unburned converter dust react with each other and separate CaCO3. The separation ends in one hour irrespectively of the mixing ratio between both slurries. If the slurries are filtered with a filter press or the like, the CaCO3 acts as a filter aid, and cake of about 25% water is easily obtained. The formation of scale is obviated as well by utilizing the filtrate for the circulating liquid to the blast furnace and the converter.

Abstract: PROBLEM TO BE SOLVED: To obtain best data signals during a reproducing and a writing by optimizing the amount of an offset of focus during a focus adjustment. SOLUTION: Every time a focus current is increased, voltages having amplitudes of difference signals corresponding to address information are successively taken in.

Similarly, every time a focus current is increased, the voltages of signal amplitudes of the difference signals corresponding to main information are successively taken in. When main information data in the certain magneto- optical disk 1 are detected at a peak of the signal amplitudes by a prescribed threshold value, a voltage DA2 of the detector 11a is stored during the detection.  Then, (DA1+DA2)/2 is computed from the two values, outputted and an offset voltage is set by a motor driver/tracking focus control circuit 4.
