Title: Selector valve
Inventor: SHIMAZU TOMOYUKI
IPC: F16K11/052
Filed: 2013-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a selector valve which can switch with small force and which has high seal performance and durability.SOLUTION: By moving a valve body in a valve chamber, a flow passage opened to an inner wall surface of the valve chamber is opened/closed. When the valve body is in a position for closing the flow passage, a valve body energization part energizes the valve body and presses it against the inner wall surface. However, when the valve body is moved to the position for not closing the flow passage, a contact part comes into contact with the valve body and presses and shrinks the valve body energization part, so that the valve body comes into a state of being separated from the inner wall surface. Therefore, the valve body and the inner wall surface do not slide with each other, so that the valve body can be moved with small force. As a result, switching can be performed with small force, and also, as the valve body and the inner wall surface do not slide with each other, the risk of deterioration of seal performance due to a foreign object and the like and deterioration of durability can be suppressed.

Title: Arc welding method
Inventor: MORI DAISUKE
IPC: B23K9/00
Filed: 2013-11-15
Abstract: PROBLEM TO BE SOLVED: To deepen the penetration of a welding start portion and a stationary welding portion and to improve the bead appearance in a spray transfer welding.SOLUTION: When the completion of a transient state Tk is determined during an arc start time, the oscillation of a welding current Iw is started. The oscillation of the welding current Iw is the repetition of the energization of a first welding current Iw1 during a first period T1, a second welding current Iw2 during a second period T2, and a third welding current Iw3 during a third period T3. Since the welding current Iw is not oscillated during a transient state Tk, the bead appearance can be improved. Then, during the first period T1 the molten metal just below the wire is made to a thinner state, during the second period T2 the arc is concentrated just below the wire, during the third period T3 a molten pool is heated concentrically, and then the molten pool is made to be moderated. Thereby, the penetration of a welding start portion and a stationary welding portion can be deepened and thus the bead appearance is improved.
