Abstract: This invention relates to a sheet post-processing device and an image-forming device. The mechanism that arranges sheets to be a bundle and that discharges the bundle will be reduced in size and cost. A sheet S1 guided by the guide 44 is conveyed to a tray 12 by a discharging roller 21. When the rear end &agr; of the sheet S1 locates on a arranging table 41, the discharging roller 21 rotates in the opposite direction, and the sheet is conveyed until the sheet contacts the stopper 43 of the arranging table 41. The next sheet S2 is conveyed to the tray 12 in the same manner as previous described, however the previous sheet S1 is held on the arranging table by the holding device 51. The sheet S2 contacts the stopper 43 by the reverse rotation of the discharging roller 21 to be arranged on the sheet S1. A bundle of sheets bound by a stapler 60 is discharged to the tray 12 completely by the discharging roller 21.

Abstract: An integrated circuit device has a memory area that includes a data memory. The data memory has a counter element and an indicator element. The counter element counts at least one number of occurrences of events within the device. When the counter element reaches a threshold value, which is indicative of a large maximum number of occurrences of the events, the indicator element goes from a first state to a second state.

Abstract: A drill bit has a bit body and at least one roller cone rotatably mounted on the bit body. The cone has a plurality of milled teeth at selected locations on the cone. At least one of the milled teeth has a substrate having a convex crest and a layer of hardfacing applied to the convex crest. The convex crest is adapted to produce at least one of a convex axial stress distribution, a substantially even axial stress distribution, and a substantially smooth axial stress distribution.

Abstract: The hair dryer includes a housing body that includes an air intake opening and an air outlet opening. The air outlet opening includes a non-ionized air outlet opening and an ionized air outlet opening. A fan is disposed within the housing body for introducing air into the housing body through the air intake opening and directing the air to the air outlet opening. An ionized air passage mechanism is formed within the housing body and is connected to the ionized air outlet opening. An air ionizing device is disposed within the ionized air passage mechanism for generating ionized air. Under this configuration, ionized air generated by the air ionizing device is discharged from the ionized air outlet opening and non-ionized air is discharged through the non-ionized air outlet opening such that both ionized air and non-ionized air are blown together from the air outlet openings of the hairdryer against hair.
