Abstract: A method of controlling an SDN system, an SDN sub-controller, and an SDN system is provided. The SDN controller sends a keepalive notification to the SDN switch and the SDN sub-controller. The SDN switch sends a switching request to the SDN sub-controller on condition that the keepalive notification cannot be received during a predetermined specific period. The SDN sub-controller starts to control a communication setting of the SDN switch on condition that the keepalive notification cannot be received during the specific period and that the switching request has been received.

Abstract: The present invention provides a rain-guard device for shipping that can prevent water from seeping into a hatch opening. A rain-guard device for shipping 20, includes a rail 19, which is placed on a sliding hatch cover 11, an on-board chute 22, which is provided in the rail 19 in a travelable manner, which covers part of a hatch opening 13, and which, furthermore, supplies cargo from a shiploader 1 into the hold 7, a lid member 23 to cover the rest of the hatch opening 13, and a water-blocking part 100, which prevents water from seeping into the hatch opening 13, through a gap between the lid member 23 and the sliding hatch cover 11.

Abstract: The present disclosure provides a rain-guard device for a nozzle that can prevent the cargo being loaded aboard from getting wet with rainwater. A nozzle rain-guard device 30 has a nozzle cover 31, which covers an outer periphery of a nozzle 8 of a shiploader 1, and a chute cover, which is provided in a lower end part of the nozzle 8, and covers a chute 22 provided on a hatch opening 13 from above.

Abstract: A rain-guard device for shipping is provided that can restrain water from seeping from an end part of the lid member. A rain-guard device for shipping 20 includes a rail 19, which is placed on a sliding hatch cover 11, an on-board chute 22, which is provided in the rail 19 in a travelable manner, which covers part of a hatch opening 13, and which, furthermore, supplies cargo from a shiploader 1 into the hold 7, and a lid member 23 to cover the rest of the hatch opening 13. The lid member 23 is formed in an arch shape in cross section. A waterproof seal 92 for restraining water from seeping into the lid member 23 is provided at an end part of the lid member 23 opposite to the ship chute 22 among end parts of the lid member 23.

Abstract: The wind-and-rain guard device for shipping is provided that can restrain wind and rain from seeping in from between the sliding hatch cover and the hatch coaming. The wind-and-rain guard device for shipping 30 includes a water-stop member 31 that closes a gap formed between a sliding hatch cover 11 and a hatch coaming 14 when the sliding hatch cover 11 is lifted from the hatch coaming 14.

Abstract: There is provided a method for manufacturing a turbocharger bearing housing which can prevent a collapsible core from being damaged when molten metal is cast in the mold. The method for manufacturing a bearing housing of a turbocharger is that the bearing housing of the turbocharger is formed with a cooling passage for circulating cooling liquid by casting using a collapsible core. The collapsible core includes the end part forming portions (a one end forming portion and an other end forming portion) corresponding to the end portions of the cooling passage and having a substantially elliptical cross-section, and a fixing portion holding the end part forming portions and being embedded in a mold and fixed to the mold.

Abstract: A heating process makes a temperature of joining surfaces Wa and Ta of a pair of metal parts W and T at the start of a first joining process equal to 20% or greater, preferably, 40% or greater of a melting point of material of the metal parts W and T. The heating process makes a heating depth h of the pair of metal parts W and T at the start of the first joining process equal to 1.0 mm or greater.

Abstract: This disclosure relates an attachment structure of a door sash of the vehicle door. The vehicle door of this disclosure includes: a door sash; a bracket, which joins the door sash to an inner panel; and a patch, which is joined to the bracket and the door sash and which sandwiches the door sash in cooperation with the bracket, thereby reinforcing the bracket.
