摘要:
As the present invention is adapted to receive an image to be printed or to be saved from a portable device having the image by wireless communication, an image needs not to be passed via a memory card or by connector connection or the like. As the present invention is also adapted to automatically identify the other party's device to wirelessly communicate with and establish a channel, and further adapted to supply power to the other party's device without contact, it is advantageous that a battery of the portable device is not exhausted or the portable device is not disconnected even if the device communicates wirelessly for a long time.

The present invention provides a high-efficiency absorption refrigerating machine which can recover heat from a heat source and can efficiently recover heat from an internal cycle. The absorption refrigerating machine includes an evaporator, an absorber (A), a condenser (C), a high-temperature regenerator (GH), a low-temperature regenerator (GL), a low-temperature solution heat exchanger (LX), and solution paths and refrigerant paths by which these units are connected. The absorption refrigerating machine further comprises two branch solution paths branched from a solution supply path through which a dilute solution is introduced from the absorption (A) to the high-temperature regenerator (GH). On one of the branch solution paths, there is disposed a drain heat exchanger (DX) operable to perform heat exchange between the dilute solution in the branch solution path and an exhaust heat source which has heated the high-temperature regenerator (GH). On the other of the branch solution paths, there are disposed a first high-temperature solution heat exchanger (HX1) and a second high-temperature solution heat exchanger (HX2) operable to perform heat exchange between the dilute solution in the branch solution path and a concentrated solution heated and concentrated in the high-temperature regenerator (GH). The absorption refrigerating machine is configured such that the dilute solution flows through the first high-temperature solution heat exchanger (HX1) and the second high-temperature solution heat exchanger (HX2) in this order, and the concentrated solution discharged from the high-temperature regenerator flows through the second high-temperature solution heat exchanger (HX2) and the first high-temperature solution heat exchanger (HX1) in this order.

The present invention relates to a plate heat exchanger for simultaneously exchanging heat between two sets of fluids having different temperatures. The plate heat exchanger comprises a heat exchange element (2) comprising two plates facing each other so as to form a inner sealed space as a passage for a first fluid, and a plate surface of the plate serves as a heat transfer surface, and a fluid flowing along an outer surface of the plate is a second fluid. The plate heat exchanger comprises a heat exchange element (2′) comprising two plates facing each other so as to form a inner sealed space as a passage for a third fluid, and a plate surface of the plate serves as a heat transfer surface, and a fluid flowing along an outer surface of the plate is a fourth fluid. A plurality of the heat exchange elements (2) and a plurality of the heat exchange elements (2′) are alternately disposed in such a manner that the plate surfaces of the plates are opposed to each other and a predetermined gap is formed between adjacent the heat exchange elements. A communication pipe communicating with the inner spaces of the heat exchange elements (2) and a communication pipe communicating with the inner spaces of the heat exchange elements (2′) are formed on the plate surfaces of the heat exchange elements (2) and (2′) and integrally formed with the elements.

A substrate processing apparatus includes a reaction chamber with a structure allowing pressure reduction, a shower head for supplying a processing gas into the reaction chamber including a gas diffusion plate in which through holes are formed, and a substrate support for placing a substrate. Each ones of through holes provided in a peripheral region of the gas diffusion plate is formed so that an area of an inlet thereof is larger than an area of an outlet thereof. With use of the substrate processing apparatus, a processing gas can be supplied uniformly in the gas diffusion plate. Therefore, substrate processing such as film deposition and film etching can be uniformly performed.
