Title: Consumable electrode type gas shielded arc welding equipment
Inventor: UKAI JIYUN
IPC: B23K9/06
Filed: 1979-07-02
Abstract: PURPOSE: To eliminate the formation of any spatter at the arc starting of the titled equipment by  reversely running a core wire feed motor upon detecting of the short-circuiting of a detector and  running the same forward upon detecting of arc thereby throwing a welding electric power source  of a constant voltage characteristic between the core and the base metals to be welded.   
     CONSTITUTION: When the switch of a welding torch is pushed, a control electric power source 11  is turned on to run a DC motor 10 forward which in turn feeds a filler core wire 6, thence a shielding gas 5 flows and only the starting electric power source 13 is turned on. Even if the core wire 6  is fed and is short-circuited to the base metal 7 to be welded, the eletric power source 13 is of a  constant current characteristics; therefore, only the set current flows and the melt-cutting of the  core wire 6 does not occur, hence any harmful spatter is not produced either. Next, a detector 14  detects the short-circuiting and emits a reverse running command of the motor 10. Since the core  wire 6 is detached from the base metal 7 while the electric current from the power source 13 is  being held flowed, an arc is generated. When the device 14 detects that proper arc voltage is  reached at this time, it emits a forward running command of the motor 10 and lets the welding  power source 8 to turn on, thereby shifting the welding into the welding by the constant voltage  characteritic power source.

Abstract: PURPOSE: To prepare steviol glucoside, by adding steviol to Murashige-Skoog medium free of agar, sterilizing the medium, transplanting a callus of Stevia rebaudiana Bertoni to the medium, and culturing the callus at room temperaure under light irradiation.

A callus of Stevia rebaudiana Bertoni is transplanted to the medium and cultured at room temperature under light irradiation of about 1,000W30,000 lux. The cultured product is extracted with methanol, etc. to separate the steviol glucoside accumulated in the callus and the medium. Since the accumulation of components other than the sweetening substances exsisting in the natural stevia is negligible, it is not necessary to eliminate the impurities from the medium, which is an essential process in the extraction of sweetening substances from natural stevia.

Abstract: PURPOSE: Polyphosphoric acid is added to a liquid medium containing alkaline earth metals and the pH of the medium is adjusted with ammonia to help the utilization of the polyphosphoric acid as the phosphorus resource by preventing the formation of hard soluble salts.  
     CONSTITUTION: More than 0.005g/dl, as phosphoric acid, of polyphosphoric acid or its salt is added to a liquid medium containing alkaline earth metals, before or after a microorganism is inoculated. During the cultivation, when the pH of the medium comes down lower than the specified value, ammonia gas or aqueous ammonia is added to adjust the pH to the specified value. When the specified pH is lower than 5, the effect is not always sufficient, because the formation of hard soluble salt is little, however, the effect is remarkable, when the pH exceeds 5. The polyphosphoric acid may have any polymerization degree, however, the product with 2W20 polymerization degree are readily available, because it is sold commercially.

Further, outputs of scan number converting circuits 62 and 63 are inputted to time-base compressing circuits 64 and 65, which compress the time base to half. Therefore, chromaticity signals CW and CN after the time base is compressed have a signal band of 8 MHz twice LPFs 31 and 32. Further, the band of the chromaticity signals CW and CN is set to 4 MHs while the band of the luminance signal Y is 16 MHz and vertical resolution is reduced to half by thinning out lines, there is almost no picture deterioration and the band can be compressed. Further, a recording signal band is uniform between respective channels and divided into the two channels to perform efficient recording.
