A cooling device that cools a semiconductor component mounted on a surface of a substrate includes a base attached to a back surface of the substrate, and a bottom plate disposed spaced apart from the base. A recessed part recessed toward the substrate side is formed in a region that is a surface, of the base, facing the bottom plate side and corresponds to the semiconductor component.

Cooling device

A furnace monitoring device for monitoring the inside of a gasifier through which a combustible gas flows is provided with: a nozzle that has an internal cavity, and that is inserted inside the gasifier and fixed to the gasifier; a cylindrical protection tube which is inserted into the nozzle, and a part of which, located on the inside of the gasifier is, blocked; a monitoring window which is provided on the protection tube on the inside of the gasifier, and is made of a material that transmits light; a purge mechanism which supplies a gas containing an oxidizer to a surface of the monitoring window facing the inside of the gasifier; and an image capturing means which captures an image of the inside of the gasifier through the monitoring window.

There is provided a safety device for aircraft, that prevents an explosion of a fuel tank storing aviation fuel, the safety device including: a flame arrester that is arranged near an end of a ventilation passage on an aircraft outer side, as a part of the ventilation passage allowing the inside of the fuel tank and an outside of the aircraft to communicate with each other, to prevent a flame propagation into the fuel tank from the outside of the aircraft through the ventilation passage; and a heat transfer reducing part that is arranged closer to the outside of the aircraft than the flame arrester to prevent heat transfer to the fuel in the fuel tank from the flame.

Safety device for aircraft

The present invention provides a water inflow prevention device that prevents an inflow of water into an aircraft when the aircraft lands in water through a communication passage allowing the inside and outside of the aircraft to communicate with each other. The water inflow prevention device includes a mesh part provided in the communication passage, through the mesh part a fluid flowing through the communication passage passes.

The present invention provides an aircraft safety device which can reliably prevent explosion of a fuel tank even if an inflammable gas is ignited. A safety device for explosion-proofing a fuel tank which stores fuel of an aircraft includes: a flame propagation blocking part which blocks propagation of a flame from the outside to the inside of the fuel tank through a ventilation passage which allows ventilation between the inside and the outside of the fuel tank; and a gas supply suppressing part which, when heated by the heat of the flame, suppresses supply of an inflammable gas containing the fuel gas to the flame through the ventilation passage.

A steel plate splicing facility includes, a steel plate heating apparatus for retrieving and heating a preceding steel plate and a following steel plate, and a shear-joining apparatus for clamping a tail end portion of the preceding steel plate and a leading end portion of the following steel plate in an overlapping condition by a die and a clamp and shearing them with a punch, such that surfaces of the tail end portion and the leading end portion are newly formed and brought in contact with each other in order to them. The shear-joining apparatus joins the preceding and following steel plates at a temperature equal to or higher than 350&#xb0; C. and at a percentage clearance c/t equal to or lower than 5%, c/t being defined by c/t=D/(t+t)&#xd7;100 where D represents a distance between the punch and the die, and tand trepresent a thickness of respective steel plates.

An apparatus and a method for suppressing growth of an oxide film on a coil which is a spirally wound, rolled strip are disclosed. A rolled strip subjected to rolling by hot rolling equipment is wound spirally by a down-coiler to make a coil. Covers are disposed on the opposite sides of the coil such that heat resistant materials intimately contact the opposite sides of the coil. The covers are fixed by L-bolts and nuts to cover the opposite sides of the coil with the covers. In this state, the coil is naturally cooled for a predetermined time to suppress growth of an oxide film and increase productivity.

A system and a method are disclosed for preventing scale defects during hot rolling by hot rolling equipment having a scale breaker provided at an entry side of a finishing mill line composed of a plurality of rolling mills arranged in tandem. A descaler is provided between a first stage rolling mill and a second stage rolling mill of the finishing mill line. A cooler for cooling a hot rolled steel plate is provided between the second stage rolling mill and a third stage rolling mill of the finishing mill line. A control device is provided for controlling the descaler and the cooler to be selectively driven such that neither of the descaler and the cooler is actuated, one of the descaler and the cooler is actuated, or both of the descaler and the cooler are actuated, according to rolling conditions. Thus, the hot rolled steel plate is rolled, with its oxide film thickness at an entry side of the third stage rolling mill being restricted to not more than a limiting oxide film thickness of 5 &mgr;m. Consequently, scale defects are prevented, and overcooling of the hot rolled steel plate is suppressed, to improve the quality of a product.

A plurality of finishing mills for finish rolling a rolled material are located in a row to configure a finishing mill group. First to third surface coolers for cooling surfaces of the rolled material are located on an entry side of each of first, second and third finishing mills of the finishing mill group, and the amount of cooling water jetted at the rolled material by each surface cooler under a command of a controller is set at 4,000 liters/min.multidot.m.sup.2, whereby the thickness of scale is restricted to 5 .mu.m or less.

Method and system for suppressing surface oxide film during hot finish

A plurality of finishing mills for finish rolling a rolled material are arranged in a row to form a finishing mill group. A scale breaker is provided at an entry side of the finishing mill group, a glass coating material application device for jetting molten glass to upper and lower surfaces of the rolled material to form a molten glass film is located at a delivery side of the scale breaker, and a molten glass film removing device for removing the molten glass film formed on the upper and lower surfaces of the rolled material is located at the delivery side of the finishing mill group.
