Abstract: An upwind wind turbine includes a tilting coupling mechanism configured to couple base end portions of blades to a hub such that the blades can tilt between a normal position and a retracted position in which the blades are tilted in a downwind direction relative to the normal position. The upwind wind turbine also includes a tilting drive operating in association with the tilting coupling mechanism to switch the positions of the blades and a rotation stop to stop the rotation of the rotor. When the blades are switched to the retracted position, the rotation stop is actuated to stop the rotor in a predetermined rotational position in which the blades can tilt without interference with the tower, and the tilting drive is actuated to tilt the blades to the retracted position after stop of the rotation of the rotor.

Abstract: An upwind wind turbine (1) of the present invention includes a tilting coupling mechanism (15), a tilting drive means (40) and a rotation stop means (18). The tilting coupling mechanism (15) is configured to couple base end portions of blades (6) to a hub (5) such that the blades (6) can tilt between a normal position and a retracted position in which the blades (6) are tilted in a downwind direction relative to the normal position, and the tilting drive means (4) operates in association with the tilting coupling mechanism (15) to switch the positions of the blades (6). The rotation stop means (18) stops the rotation of the rotor (4). When the blades (6) are switched to the retraced position, the rotation stop means (18) is actuated to stop the rotor (4) in a predetermined rotational position in which the blades (6) can tilt without interference with the tower (2), and the tilting drive means (15) is actuated to tilt the blades (6) to the retracted position after stop of the rotation of the rotor (4).

Abstract: A paper folding mechanism for folding continuous paper is provided. The folding mechanism includes a swing guide caused to pivot for guiding the paper, and first and second paper guides which are spaced from each other. The first paper guide is displaceable relative to the second paper guide. The folding mechanism also includes a paper presser arranged adjacent to the first paper guide for folding the paper along fold lines. The paper presser is designed to move relative to the first paper guide.

Abstract: A device used in a multimedia communication system is formed with a transceiver unit for transmitting and receiving information signal to and from the inside of a room and a base unit adapted to be mounted to a wall of the room to detachably support the transceiver unit. The transceiver unit has a plug surface on which a plug projects, a circular wall projecting on the plug surface to surround the plug, and a guide wall projecting on the plug surface inside the circular wall and around the plug. The base unit comprises a disk member which is provided with a receptacle exposed in a receptacle surface defined on the disk member. The disk member has a diameter slightly smaller than an inner diameter of the circular wall so that the disk member can fit within the circular wall when the transceiver unit is attached to the base.

Abstract: An electronic translator comprises a memory circuit for storing words which is removable from the translator, an attachment connectable to the translator, and a coupling device permitting either the memory circuit or the attachment to be connected to the translator. The coupling device is provided within the translator. The attachment may be a printer or an audible sound generator.

Abstract: A memory circuit for an electronic dictionary or translator is provided for storing some number of entry words by grouping them into some groups for including a substantially same number of entry words. A group selection means is provided for selecting a specific group, such that the selected group of entry words are outputted subsequently, so that a specific entry word is selected.

Abstract: An electronic translator comprises an input device for entering a first word or words, a first memory circuit for storing the first words, a second memory circuit for storing second words equivalent to the first words, an access circuit for addressing the memory circuits to cause retrieval of the first word or words, or alternately the second word or words, and a control circuit for controlling activation of the access circuit. There may be additionally provided a holding circuit for holding one or more of the first words without translation thereof.

Abstract: An electronic translator is featured in which sentences as stored are modified by replacing one or more words in one of the original sentences with one or more new words and by changing automatically one or more additional words in the original sentence, depending on the nature of the one or more new words entered in the sentence. For example, the one or more additional words may be definite articles or prepositions.
