Abstract: A server displays a co-evaluation request containing an evaluation scheme of a first evaluator on a homepage. A second evaluator browsing the co-evaluation request through a terminal device transmits a proportion of user's own assignment as an answer to the server. The server displays the proportion of assignment of the second evaluator on the homepage. Thereafter, each of the first and second evaluators respectively transmits evaluation results of the co-evaluation to the server. The server displays each evaluation result received on the homepage.

Abstract: A server displays a co-evaluation request containing an evaluation scheme of a first component user on a homepage. A second component user browsing this co-evaluation request through a terminal device transmits a proportion of user's own assignment as an answer to the server. The server displays the proportion of assignment of the second component user on the homepage. Thereafter, each of the first component user and the second component user transmits an evaluation result of the co-evaluation to the server. The server displays each evaluation result received on the homepage. The first and second component users exchange the evaluation results through the homepage, and can share the co-evaluation results on the homepage.

Abstract: A bar code reader using a high speed scanner, containing: a scanning unit scanning a surface on which a bar code is printed; a bar width detecting unit successively detecting widths of bars; a bar width storing unit storing the widths; an address generating unit generating an address of the bar width storing unit at which each of the widths is to be stored; a fast screening unit determining whether a set of widths successively detected by the bar width detecting unit satisfies a predetermined condition for the set of widths constituting a complete bar code; and a bar code decoding unit reading a set of successive widths from the generated address, and decoding the bar code determined by the complete bar code detecting unit. A type of bar code detecting unit detecting a type of bar code constituted by the detected widths, and an address & type storing unit storing the detected type of bar code, together with information on the generated addresses for the widths of the bar code, may be inserted.

Abstract: A linear motor car system including a horizontal conveyance path, a vertical conveyance path, and a curved conveyance path connected between the horizontal and vertical conveyance paths. A controller in the linear motor car system drives a carrier so that the cariier can ascend smoothly up the curved and vertical conveyance paths with the minimum driving energy and without accidentally falling back down the vertical path.

Abstract: A transport control system with linear motor drive applicable for cash transport in a bank. The system uses a main controller, a rail-path, a carrier adapted to be driven along the rail-path by linear motor drive, and a plurality of stator portions coupled to the rail-path to produce a driving force in association with the carrier. Each of the stator portions includes a stator controller for controlling the driving of the carrier. The stator controller controls the driving of the carrier passing the stator portion to which the stator controller belongs to cause the carrier to reach a destination stator portion.
