Abstract:
According to one embodiment, a postal indicium detection method includes detecting whether or not one of a first face and a second face of a sheet corresponds to a picture card specific face, detecting a postal indicium candidate from the second face based on a first detection result indicating that the first face corresponds to the picture card specific face, and detecting the postal indicium candidate from the first face based on a second detection result indicating that the second face corresponds to the picture card specific face.
Abstract:
A linear actuator displaces a relative position between a guide rail and a slide table, which is arranged in confronting relation to the guide rail. Projections are formed on opposite end sides of the guide rail, the projections extending along a direction of displacement and projecting toward the slide table. The slide table is disposed between the projections on the opposite end sides of the guide rail, with rigid balls being interposed therebetween. Guide grooves and guide grooves, which rollably support the balls, are provided on the projections on the opposite end sides of the guide rail and on the slide table. The guide grooves and the guide grooves apply, on the balls, a pressure caused by a magnetic attractive force of permanent magnets.
Abstract:
An ionizer includes positive and negative wire electrodes each formed of a conductive wire with a circular cross section. The wire electrodes are arranged in parallel with each other, each having circumferential surfaces serving as a discharge surface on which a corona discharge occurs upon application of positive and negative high voltages for discharging positive and negative ions.
Abstract:
A linear actuator includes a guide block constituting a guide mechanism. In the guide block, a pair of installation grooves are formed in a lower surface facing toward a cylinder main body. Ball circulation members having therein ball circulation holes are installed respectively in the installation grooves. Additionally, ball circulation passages through which balls circulate are provided. The ball circulation passages are made up from roll-reversing sections disposed on opposite ends of the ball circulation members, the ball circulation holes, second ball guide grooves formed in both side surfaces of the guide block, and first ball guide grooves of the slide table.
Abstract:
A character recognition apparatus generates each character candidate from a character string written in a plurality of character entry boxes written on a sheet of paper such as a business form, and performs character recognition. A row image separating unit acquires an image containing a plurality of character entry boxes and the character string. A character extraction processing unit detects each point at which a plurality of lines are in contact with each other and intersect in the character string contained in the image, determines a point at which the character string should be cut or recombined on the basis of the placement relationship between the point and the corresponding character entry box, and generates each character candidate constituting the character string. A character recognition unit performs character recognition for each character candidate generated by the character extraction processing unit.
Abstract:
When charges are removed from a charged workpiece by applying positive and negative pulse-like high voltages to positive and negative electrode needles to generate positive and negative ions in a charge removing area and feeding the charged workpiece into the charge removing area, an ion balance inside the charge removing area is measured by a surface potential sensor before the workpiece is fed into the charge removing area, and a pulse width and/or a voltage value of the pulse-like high voltage applied to the electrode needle is changed depending on a measured result, thereby adjusting an amount of ions generated from the electrode needle to take a balance between the positive and negative ions.
Abstract:
In an ionizer composed of an electrode needle cartridge and a main body block, the electrode needle cartridge is provided with an electrode needle for generating an ion, a high voltage generating device for applying high voltage to the electrode needle, and a receiving connector for connecting a feeding connector, and the main body block is provided with an air-blowing outlet serving as an electrode needle housing portion, an air passing-through hole for supplying air to the air-blowing outlet, and a connecting port for connecting an air piping. The electrode needle cartridge is configured such that when the electrode needle cartridge and the main body block are connected or separated, the electrode needle is inserted into or removed from the air-blowing outlet from a rear end portion side of the air-blowing outlet.
