Abstract: In a riding work vehicle, power of an engine is transmitted to a traveling wheel via a horizontally oriented transmission shaft and a vertically oriented transmission shaft. The traveling wheel is supported to be changeable in direction about a rotational axis of the vertically oriented transmission shaft. Each of the vertically oriented transmission shaft and a vertically oriented transmission case is provided as an inner/outer double structure expandable/contractible in association with sliding movement thereof. The vertically oriented transmission case is supported to be pivotable together with the traveling wheel. There is provided a vehicle height adjustment mechanism capable of switching, in a plurality of steps, a relative height of the traveling wheel relative to a vehicle body frame.

Abstract: The present invention discloses a method for evaluating vitality of a plant including (a) a step of measuring a delayed luminescence of a leaf of each plant of a group of plants subject to evaluation to obtain data of delayed luminescence amount, and (b) a step of processing data of a plurality of delayed luminescence amounts thus obtained to evaluate a plant exhibiting a delayed luminescence amount not less than a preset upper limit threshold as an individual of poor growth or evaluate a plant exhibiting a delayed luminescence amount not more than a preset lower limit threshold as an individual of good growth, and a measurement system and an evaluation system used for the method.

Abstract: The present invention is for shortening the time required to discover a phenomenon related to a detected event. Reverse reproduction is performed in data stream processing. Specifically, a computer system 3 processes multiple pieces of input data 141 in accordance with times in chronological order denoted by the timestamps 142 within the input data 141, beginning from input data 141 including a timestamp (hereinafter, latest reference stamp) that denotes the newest time from among the timestamps denoting times prior to a reference time (for example, an event detection time). A method for creating output data 171 including the result of this processing and output timing are controlled on the basis of the lifetime of the input data 141, which is specified by a query 131. In accordance with this, the output data is properly outputted using reverse reproduction.

Abstract: A Business to Business electronic commerce (BtoB) system includes a message exchanging section, a task processing section and that conforms to BtoB standard specifications, and a difference processing section is added. For an outgoing business document, the difference processing section creates difference information between a past transaction and a new transaction within the range of the BtoB standard message format and sends the message to a business counterpart. For an incoming business document, the difference processing section restores a new transaction based on a past transaction and difference information.
