The quatro generation system of the present invention includes: a power generation engine driven by fuel gas; an exhaust-heat boiler configured to utilize energy of exhaust gas discharged from the power generation engine to produce steam from boiler water; a boiler-water circulation device configured to supply the steam produced by the exhaust-heat boiler to a steam-energy recovery unit, and to return condensed water of the steam to the exhaust-heat boiler after the steam-energy recovery unit recovers energy of the steam; a condensation economizer configured to utilize condensation latent heat of exhaust gas discharged from the exhaust-heat boiler to heat a heat medium; and a heat-medium circulation device configured to supply the heat medium heated by the condensation economizer to a thermal-energy recovery unit, and to return the heat medium to the condensation economizer after the thermal-energy recovery unit recovers energy of the heat medium.

Quatro-generation system

An object of the present invention is to provide an atmosphere heat treatment apparatus that is operable without relying on experiences and/or intuitions of an operator, and a method of operating the same. The atmosphere heat treatment apparatus includes an entrance side exhaust path () for exhausting an inside atmosphere from an entrance side of a carburizing chamber () to which a transforming gas is supplied, an exit side exhaust path () for exhausting the inside atmosphere from an exit side of the heat treatment chamber, and an opening degree adjusting lid () attached for adjusting an opening degree of the entrance side exhaust path (), in which a part or whole of the exit side exhaust path () is constituted of a pipe () having a predetermined inside diameter. It is checked in advance a relationship of a supplying amount A of the transforming gas with a ratio B:C of an exhaust amount B from the exit side exhaust path () and an exhaust amount C from the entrance side exhaust path () when a pressure in the carburizing chamber () is adjusted to a predetermined furnace pressure by adjusting an opening degree of the entrance side exhaust path () with the opening degree adjusting lid (), and when treating a work (W), the supplying amount A of the transforming gas and a furnace pressure are adjusted so as to control the ratio B:C of the exhaust amount B from the exit side exhaust path () and the exhaust amount C from the entrance side exhaust path () to be within a predetermined range.

Atmosphere heat treatment apparatus and method of operating the same

According to one embodiment, an electronic apparatus comprises: a casing comprising a circuit module; a keyboard mounting portion on which a keyboard is detachably mounted, and a cover detachably covering the opening. The key board mounting portion comprises an opening which allows a wiring electrically connecting the keyboard and the circuit module to be passed therethrough. An area of the opening is equal to or less than half of an area of the keyboard mounting portion.
