An air flow rate sensor and throttle valve which controls the opening of a duct in accordance with the detection signals from the air flow rate sensor are provided in a control duct between a supply chamber utilizing double ceilings and the air diffusers in the supply chamber. The quantities of air fed from the respective air diffusers can be equalized or can be set to the desired values. In this case, since the air blowing can be automatically controlled for each diffuser, it is not necessary to individually adjust the quantities of air for the respective air diffusers after the installation of the air conditioner, thereby eliminating the adjusting works of the air diffusers.

A curve formed by an inner surface of a face panel in a cross-section including a tube axis of a color picture tube is defined. The face panel includes at least one cross-section in which the curve has an inflection point between a center of the face panel and a circumferential edge of an effective display region. Assuming that a maximum value of an angle formed by a tangent of the curve and a plane orthogonal to the tube axis between the center of the face panel and the inflection point is θA, and a minimum value of an angle formed by the tangent of the curve and the plane orthogonal to the tube axis between the inflection point and the circumferential edge of the effective display region is θB, the curve having the inflection point satisfies 0.6≦θB/θA<1.0. Because of this, a color picture tube having satisfactory screen quality can be provided.

An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.

In-line color display tube (1) with a deflection unit (7), provided with a twist correction device comprising two permanent magnets (15, 15') which generate magnetic fields with oppositely directed magnetic field components which, at the beginning and the end of a path traversed by each side beam, are transverse to the path of the relevant side beam and are located in the plane of the beams. This provides the possibility of deflecting each side beam once up and once down for compensating twist errors.
