Abstract: A variable nozzle is comprised of: an exhaust duct vectoring a flow of the exhaust gas to the aft end; a plurality of primary flaps arranged to define a primary flow path converging toward the aft end, each of the primary flaps being swingably pivoted on the exhaust duct to regulate a degree of opening the primary flow path and including a first section and a second section forming an angle axially outward relative to the first section; and a plurality of secondary flaps arranged to define a secondary flow path in communication with the primary flow path, the secondary flow path being capable of divergent toward the aft end, the secondary flaps being respectively swingably pivoted on the second sections of the primary flaps to regulate a degree of opening the secondary flow path.

Abstract: An output data processing device capable of increasing efficiency in setting of parameters is provided. Output conditions suitable for each medium to be printed are stored beforehand in relation to each medium. Each time an order is received, the details of the order, print data and a medium are stored in relation to each other in a publication management database. By only selecting a record corresponding to the details of the order among the records stored in the publication management database for an output process, the related output conditions and the corresponding print data are transferred to an output device which in turn performs the output process. Thus, the efficiency is increased in a condition setting process entailed in the output process.

Abstract: An operating handle for a fishing reel having a drive shaft. The handle is movable between a folded position when the reel is not in use and a standing position when the reel is in use. The handle includes an arm which is pivotally connected to one end of a stud cooperable with the drive shaft. A sliding member, movable only axially with respect to the stud and located about the stud, abuts one end of the arm. An operating member, rotatably supported about the sliding member, operates a control mechanism which limits axial movement of the sliding member. Rotational movement of the operating member enables the sliding member to slide axially so that the arm may pivot to move into the folded or standing positions.
