摘要： An antifogging device includes: an optical system having one or a plurality of optical members including at least an objective lens; a hollow casing in which the optical system is stored; a heater configured to generate heat according to supplied power to heat a hollow space in the casing; a temperature sensor configured to detect temperature of the hollow space; a temperature controller configured to estimate temperature difference between the temperature detected by the temperature sensor and temperature of the optical member, based on a power value of the supplied power; and an overall controller configured to control the heater based on the temperature difference estimated by the temperature controller.

摘要： A medical treatment apparatus is an apparatus for treating a living body tissue by heating the living body tissue. The apparatus includes a heat transfer portion, a heating chip and a flexible substrate. The heat transfer portion is configured to come into contact with the living body tissue and transfer heat to the living body tissue. The heating chip is disposed on the heat transfer portion and is configured to heat the heat transfer portion. The flexible substrate is partly joined to a first surface of the heat transfer portion on which the heating chip is disposed, with a remaining portion extending outside the heat transfer portion. A heating trace for supplying power to the heating chip is formed on the flexible substrate.

摘要： A heater unit includes a heater which is provided inside of a distal end portion of an endoscope insertion portion and which heats the inside to prevent fogging which occurs in an optical member provided the inside, a temperature sensor which measures the temperature of the inside and a flexible substrate. The heater unit further includes an insulating sealing portion which seals a mounting surface of the heater mounted on the flexible substrate, which seals the heater so that so that a joint surface of the heater that faces the mounting surface and that is joined to the lens frame is exposed and which seals the whole temperature sensor.

摘要： In a state in which a heat generator and a temperature sensor are disposed on a wiring board, a measurement wiring is disposed in a vicinity of the heat generator, or the temperature sensor is disposed in a vicinity of a heat-generation wiring. A suppressing portion is disposed in either a first heat transfer path extending from the heat generator to the measurement wiring or a second heat transfer path extending from the heat-generation wiring to the temperature sensor. The suppressing portion suppresses heat transfer from the heat generator to the measurement wiring in the first heat transfer path, or suppresses heat transfer from the heat-generation wiring to the temperature sensor in the second heat transfer path.
