Abstract: A work machine includes a control unit that starts cruise control that continues a travel ON mode of the travel unit even if travel levers, functioning as a travel operator, are in a state corresponding to a travel OFF mode. As a result, work is enabled to be performed at constant travel speed with ease.

Abstract: A battery (20) of power equipment (1) is received in a battery receiving recess (40) of the power equipment. A lower front end of the battery is provided with an engagement portion (140) configured to be engaged by a rib (50) provided in a lower part of the front end of the battery receiving recess. A first sheet spring member (80) is provided in a rear part of a bottom surface of the battery receiving recess to urge the battery upward. A latch member (66) provided in a rear end part of the battery receiving recess engages a rear end of the battery against the spring force of the first sheet spring member.

Abstract: A battery 20 of power equipment 1 is received in a battery receiving recess 40 of the power equipment. A lower front end of the battery is provided with an engagement portion 136 configured to be engaged by a rib 50 provided in a lower part of the front end of the battery receiving recess. A first sheet spring member 80 is provided in a rear part of a bottom surface of the battery receiving recess to urge the battery upward. A latch member 66 provided in a rear end part of the battery receiving recess engages a rear end of the battery against the spring force of the first sheet spring member.

Abstract: A machine translation system capable of performing translation at a high processing speed with improved disambiguation rate in the parsing by applying grammar rules in dependence on the domains to which texts to be translated belong, objects of the texts and rules of sentences in the same text. The machine-translation system for translating a first language to a second language uses a grammer memory for storing grammar rules of the first or second language and a main memory for storing a variety of information, wherein the grammar rules stored in the grammar memory are prepared in groups at least on the basis of the domains to which texts to be translated belong and individual parts in the text.

Abstract: A method and an apparatus for generating/maintaining automatically or interactively a lexicon for storing information of cooccurrence relations utilized for determining whether or not a sequence of words in a given sentence described in a natural language is semantically correct with the aid of a memory, a data processor and a textual sentence file. A hypothesized cooccurrence relation table for storing hypothesized cooccurrence relations each having a high probabliity of being a valid cooccurrence relation is prepared by consulting the file. A hypothesis for the cooccurrence relation is previously established on the basis of a cooccurrence relation pattern indicating a probably acceptable conjunction by consulting the hypothesized cooccurrence relation table.
