There is disclosed a heat exchanger tube for conducting refigerant in a heat exchanger. The inner surface of the tube has a convex portion having a broad tip and a plurality of inner fins. The area of the tip of the convex portion is larger than that of the tip of the inner fins. The height of the convex portion can be set at more than that of the inner fin. A heat exchanger according to the invention has a plurality of plate fins, each having a hole therein. Heat exchanger tubes pass through the holes of the plate fins. A method of manufacturing a heat exchanger comprises the steps of stacking a plurality of plate fins, each having a hole, with a predetermined space therebetween. Heat exchanger tubes are inserted through the holes. Then, the tubes are expanded to engage the plate fins. A refrigerating circuit utilizing a heat exchanger is also described.

An air-conditioning apparatus forms a refrigerating cycle with a refrigerant heater and a compressor having two cylinders. The apparatus simultaneously carries out a refrigerant heating operation and a heat pump operation when a required heating capacity is high, and when the required heating capacity is low, only the heat pump operation. This operation technique helps reduce the size of the apparatus and expand a variable width of heating capacity. The apparatus also has a defrosting unit for defrosting an outdoor heat exchanger during the heat pump operation.

A tilting apparatus is provided which can make a moving section perform a tilting operation with stability or in which a moving section can exercise its functionality as expected, and an electronic apparatus equipped with the tilting apparatus is provided. In a tilting apparatus, with first and second tilting operations, one side of a first panel holder is angularly displaced with respect to the other side from a reference position. This can prevent the first panel holder from making any extra operation other than the first and second tilting operations with respect to a device body. Unlike any existing technology, in the invention, even when the first and second tilting operations are put into action, a first chassis is not displaced against the device body unless it is desired, e.g., displaced along front, and juts from the device body, thereby favorably leading to the operation with stability.
摘要:
A toner is provided for developing an electrostatic image which has relatively high roundness, uniform shape, excellent property of electrification, electrification stability, maintenance of heat resistance, fixability, image quality and productivity, and is effective for full-color image formation, cleanerless system and toner-recycling system. The toner comprises toner particles containing a binder resin (A), a polymer (B) and a colorant, the polymer (B) having weight-average molecular weight of 1000-3000 and a ratio of weight-average molecular weight/number-average molecular weight of not more than 2.0, wherein the polymer (B) particles exist on surfaces of the toner particles.
