The present disclosure provides a drying chamber (condenser) including a container having a steam intake opening, the condenser liquefying steam taken from the steam intake opening into the container, and the drying chamber including a cooling pipe which is disposed in the container and through which coolant circulates.

Condenser and cleaning device

A carburizing device includes a furnace body that performs heat treatment on a treatment object to perform carburization treatment on the treatment object, in which: a heater configured to perform heat treatment on the treatment object is provided upright in a vertical direction within the furnace body; a gas supply section configured to supply a gas for burnout toward the heater is provided at a lower end part of the heater; the heater is inserted through a protective tube provided upright in the vertical direction; and the gas supply section is configured to supply the gas for burnout to between the protective tube and the heater.

Carburizing device

A cleaning apparatus includes: a cleaning chamber that accommodates an object to be cleaned; a drying chamber connected to the cleaning chamber; a connecting member connecting a first opening provided in the cleaning chamber and a second opening provided in the drying chamber; a valve element positioned inside the cleaning chamber and facing the first opening; a valve seat facing the valve element; and an actuator that drives the valve element.

Cleaning apparatus

A carburizing device is configured to perform a carburizing treatment on a treatment target, and includes a furnace body, an insulating container provided inside the furnace body, a furnace bed provided inside the insulating container and on which the treatment target is mounted, and a heat source provided inside the insulating container, in which at least surfaces of main components of the furnace bed, the heat source and the insulating container are made of a ceramic material.

Vacuum cleaning apparatus () includes a vapor generating member () for generating vapor of a petroleum-based solvent, a cleaning chamber () allowing a workpiece to be cleaned under reduced pressure by the vapor fed from the vapor generating member, a condensing chamber () that is connected to the cleaning chamber and is maintained in a depressurized state, a temperature maintaining member () that maintains the condensing chamber at a lower temperature than the cleaning chamber, and an opening/closing member () that provides or cuts off communication between the condensing chamber and the cleaning chamber.
