Abstract: PURPOSE:To perform arc welding with the little quantity of occurrence of spatters by time-dividing a first time limit by a pulse current part and a base current part to execute output alternately and regulating a current according to the presence or absence of a contact short circuit after the lapse of a second time limit.

After the lapse of the prescribed second time limit shorter than the first time limit with the output starting time of a pulse current as a time starting point, when there is no contact short circuit between a wire and material to be welded and an arc is maintained, the next pulse current is then outputted by the basic pulse period. In addition, after the lapse of the second time limit, when there is the contact short circuit between the wire and the material to be welded, the current with a value lower than the rising speed of the pulse current during a subsequent wire contact short-circuit period is outputted. When the wire contact short circuit is then released, after third output control different from the pulse current part is executed during a prescribed third time limit, the next pulse current output is started and an action in the basic pulse period is restored.

IPC: F02M37/00
Filed: 1986-04-23
Abstract: PURPOSE:To aim at enhancing the control ability and starting ability of an internal combustion engine, by providing such an arrangement that a pump is driven when a power source switch for the engine is turned on to feed fuel into a fuel supply passage from a fuel tank. CONSTITUTION:When a power switch 4 is turned on, the voltage of a battery is applied to a power source circuit 6 for a pump drive means and a control means 15. The output of an AND circuit 26 is high so that the output of a NAND circuit 34 becomes low to deenergize a transistor 38, resulting in energization of a transistor 9 in a power source circuit 9. Accordingly, a motor driven pump 7 is operated to feed fuel into a fuel hose from a fuel tank. When the pressure in the fuel hose is increased, a detection switch in a pressure detecting sensor 31 is opened so that the output of the AND circuit 26 becomes low. Accordingly, the output of the NAND circuit 34 becomes high to energize the transistor 38, resulting in deenergization of the transistor 9 in the power source circuit 6. Therefore, the power source voltage of the motor driven pump 7 is cut off and the pump is therefore stopped.

Filed: 1984-05-09
Abstract: PURPOSE:To make easy fractional measurement of ions which exist mixedly in a sample, are different in the oxidation state and are of the same ion species by each oxidation state by using a flow injection analyzing (FIA) method. CONSTITUTION:The reagent to be passed at all times among a color forming reagent, buffer reagent, reducing reagent and oxidation reagent is only the color forming reagent from a vessel 1. Either of the buffer reagent from a vessel 2 and the reducing reagent or oxidation reagent from a vessel 3 is selected by a selector valve 5. Only the ion quantity to allow the color forming reagent to form a color in the sample introduced through an injecting port 6 is measured by absorptiometry using a detector 10 when the buffer reagent is selected. The total ion in the sample can be detected as all the ions in the sample can be converted to the ions which can allow the color forming reagent to form a color when the reduction reagent or oxdation reagent is selected. The easy analysis if the ions by each oxidation state with high accuracy is made possible without requiring the pretreatment for the sample according to this method.
