摘要:
An indoor unit of an air conditioning apparatus includes a casing, a heat exchanger, a fan, a first airflow direction adjusting plate adjusting a direction of airflow blown out from an air outlet by rotation about a first axial direction, a plurality of second airflow direction adjusting plates adjusting the direction of the airflow blown out from the air outlet by rotation about a second direction substantially perpendicular to the first direction, and a support member rotatably supporting the first airflow direction adjusting plate in the air outlet other than at both end portions. The second airflow direction adjusting plates include a third airflow direction adjusting plate and a fourth airflow direction adjusting plate placed in a location such that a distance to the support member from the fourth airflow direction adjusting plate is smaller than a distance to the support member from the third airflow direction adjusting plate.

摘要:
Characteristics of a circuit element are predicted accurately by taking account not only of the temperature variation due to self-heating of the element but also of temperature variation due to heat transmission from an adjoining heater element. With reference to an electric network supplied from an electric network input unit (2) and a heat network supplied from a heat network input unit (3), a simulation unit (4) determines a first heat generation temperature resulting from the amount of self-heat generation of that element and a second heat generating temperature resulting from the amount of heat flowing into that element from other elements, respectively, for a plurality of elements which make up a semiconductor integrated circuit, calculates the element temperature of that element based on the first and second heat generation temperatures, and then calculates the voltage value and the current value in the element at that element temperature based on previously provided data indicative of temperature dependency of that element.

A semiconductor device which can actively dissipate heat in response to operation is provided. A Seebeck element 310 is buried as a thermoelectric conversion element. The Seebeck element 310 is provided inside a semiconductor element, and has one end disposed proximal to a heat generation part of the semiconductor element and the other end disposed in a distal side of the heat generation part. In addition, a Peltier element 320 is buried as a heat dissipation element. A Peltier element 320 has one end disposed proximal to the heat generation part and the other end disposed in a distal to the heat generation part, and the other end disposed in a distal end side of the heat generation part. A current according to the thermoelectromotive force generated by the Seebeck element 310 is applied to the Peltier element 320.
