Abstract: Provided is a device including: a battery configured to supply power; a heater configured to heat an aerosol generating material by receiving power from the battery; a sensor; at least one output unit; and a controller, wherein the controller detects a user's puff by using the sensor and controls at least one output unit based on puff characteristic data based on a result of the detection.

Abstract: Embodiments provide a 3-way valve and a heat pump system using same, the 3-way valve comprising: a housing in which an inlet, a first outlet, and a second outlet are disposed; and a ball valve which is disposed inside the housing, wherein the ball valve comprises: an inlet hole which is connected to the inlet and into which a refrigerant flows; a first outlet hole and a second outlet hole, through which the refrigerant flowing into the inlet hole flows out, and when the ball valve rotates, the refrigerant flowing out through the first outlet hole passes through the first outlet, and the flow rate of the refrigerant flowing out through the second outlet hole is controlled through the second outlet.

Abstract: An etch stop layer is formed over a first structure by depositing a metal oxide material over the first structure and annealing the deposited metal oxide material. A second structure is formed over the etch stop layer, and a formation is etched through the second structure using the etch stop layer as an etch stop.

Abstract: An endoscope system with a hollow cylinder and bellows moving mechanism is provided. The system includes a cylinder having a head unit mounted by a camera devices, a front fixing unit connected to the head unit which is installed to an outer circumference of the cylinder and fixed to an inner wall of an organ, a rear fixing unit slidably installed at the outer circumference of the cylinder and fixed to the inner wall of the organ, and a moving unit between the front fixing unit and the rear fixing unit for moving the head unit in the organ by an extension and contraction when the front fixing unit or the rear fixing unit fixes the head unit to the inner wall of the organ. The moving unit includes a double bellows and forms a hermetic space with the outer circumference surface of the cylinder.

Abstract: Disclosed is an endoscope system having a body comprising: a cylinder having a head unit mounted by a camera device at one side thereof and connected to a tube which is connected to an external device out of a human body at the other side thereof; a front fixing unit connected to the head unit, installed to an outer circumference of the cylinder, and thereby fixed to an inner wall of an organ; a rear fixing unit slidably installed at the outer circumference of the cylinder and fixed to the inner wall of the organ; and a moving unit connectedly installed between the front fixing unit and the rear fixing unit for moving the head unit in the organ by an extension and contraction when the front fixing unit or the rear fixing unit fixes the head unit to the inner wall of the organ.
