A paper feeding device that includes, in a drive transmission mechanism to a paper feeding roller that delivers paper, a drive member provided on an apparatus body side as a member to transmit torque in a given direction for delivery of paper from a conveying motor to the paper feeding roller and a driven member provided on the paper feeding roller side. By relatively rotating the drive member and the driven member to form a coupling state of the members before an instruction to start the delivery of paper is output, the rotation of the paper feeding roller is started without a time lag when the instruction to start the delivery of paper is output.

A leeward upper header portion of an evaporator includes first through third sections which communicate with upper ends of heat exchange tubes of first through third tube groups of a leeward tube row. The second tube group, which is an upward flow tube group, and the third tube group, which is a downward flow tube group, form a tube group set. A baffle plate is provided in the second section to be located on the side toward the third section. The baffle plate divides a portion of the interior of the second section into upper and lower spaces and prevents flow of refrigerant toward the upper space. A flow prevention member is provided below the baffle plate so as to prevent flow of refrigerant from the second section into the third section. These two sections communicate with each other in a region above the baffle plate.

A method of manufacturing a semiconductor device includes subjecting a semiconductor substrate having an aluminum film formed thereabove to a processing to at least partially expose a surface of the aluminum film, and carrying out a surface processing to remove an after-processing residue that remains on the exposed surface of the aluminum film. The surface processing includes treating the exposed surface of the aluminum film with a first liquid chemical containing an anion component and then with an alkaline, second liquid chemical.

A leeward tube row of an evaporator includes first to third tube groups, and a windward tube row thereof includes fourth and fifth tube groups. Within a third section of a leeward upper header portion with which heat exchange tubes of the third tube group communicate, a resistance member for flow division is provided so as to divide the interior of the third section into a first space which the heat exchange tubes face, and a second space which is separated from the first space and into which refrigerant flows. The resistance member for flow division has a plurality of refrigerant passage holes. The leeward upper header portion has a flow cutoff member for preventing flow of refrigerant into the first space of the third section. The third section of the leeward upper header portion communicates with the fourth section of the windward upper header portion via refrigerant communication passages.

A sheet take-out device in which sheets are conveyed in an upright state and sheets having a low height can be stably taken out is provided.A sheet take-out device includes a main floor belt that conveys sheets that are placed in an upright state in a direction intersecting a conveying direction to a take-out portion, and a take-out unit that takes out the sheets conveyed by the main floor belt one by one in order from the frontmost sheet. The device includes a sub-floor belt that is capable of reverse conveyance, in which sheets are conveyed in a direction opposite to the conveying direction of the main floor belt, a tightness detection unit, and a height detection unit that detects the height of the sheets immediately prior to being taking out by the take-out unit, and performs sub-floor control.

A heat exchanger includes a pair of header tanks, a plurality of flat heat exchange tubes which are disposed between the two header tanks and whose opposite end portions are connected to the corresponding header tanks, and a plurality of corrugate fins each including wave crest portions, wave trough portions, and connection portions connecting together the corresponding wave crest portions and wave trough portions, and each disposed between the adjacent heat exchange tubes. Each connection portion has a plurality of louvers which extend in a width direction of the connection portion and are arranged in a longitudinal direction of the connection portion. The louver pitch is 0.4 mm to 0.8 mm. The inclination angle of the louvers in relation to the connection portion is 20° to 30°.

A heat exchanger to be used as a heater core includes a pair of header tanks spaced apart from each other, a plurality of flat heat exchange tubes which are disposed between the two header tanks at predetermined intervals along a longitudinal direction of the header tanks with their width direction coinciding with an air flow direction and whose opposite end portions are connected to the header tanks, and a plurality of corrugate fins each disposed between the adjacent heat exchange tubes. Each heat exchange tube has an inner height Ht of 0.7 mm to 1.2 mm and a width of 24 mm to 30 mm as measured in the air flow direction. Each corrugate fin has a fin height Hf of 5.5 mm to 8.5 mm. This heat exchanger exhibits excellent heat radiation performance and low resistance to air flow and water flow.
