A cooking device comprises a cooking device body comprising a heating chamber for heating an object; a fan, comprising a bladed wheel and a casing having the bladed wheel in rotatable manner, to discharge air in the heating chamber; and an exhaust duct comprising an exhaust guide plane to guide the air blown out by the fan to the outside of the cooking device body. The casing comprises an arc-shaped guide plane to guide an air flow generated by a rotation of the bladed wheel in a rotation direction of the bladed wheel, and an outlet port opened from a part of the arc-shaped guide plane to one side in a tangent direction of the arc-shaped guide plane. The rotation direction of the bladed wheel is a direction opposite to the opening direction of the outlet port, and turbulence is generated in the exhaust duct.
摘要:
A cooking device has an exhaust duct (19) configured and arranged to mix together exhaust air discharged from an opening (61a) at a tip of a nozzle part (61) and part of cooling air discharged from a cooling fan and guide the mixed exhaust air to discharge it outside of a casing, and an exhaust duct temperature sensor (70) placed within the exhaust duct (19) to detect a temperature of an atmosphere inside the exhaust duct at a portion upper than the opening (61a) of the nozzle (61). A fan abnormal-stop detection part detects an abnormal stop of the fan when an increment per unit time of an atmosphere temperature inside the exhaust duct (19) detected by the temperature sensor (70) during cooking becomes equal to or higher than a first threshold value.

The present invention provides a curable composition comprising a fluorine-containing elastomer having a cyano group in its trunk chain and/or side chain and inorganic nitride particles, or a curable composition comprising a specific crosslinking agent, a fluorine-containing elastomer having a cure site crosslinkable with the crosslinking agent and inorganic nitride particles. The present invention also provides a molded article obtained by curing the above-mentioned curable composition. The present invention further provides a process for production of a molded article comprising a step of primary vulcanization of the curable composition and a step of secondary vulcanization following the primary vulcanization. The curable composition is characterized by comprising a fluorine-containing elastomer having a cyano group in its trunk chain and/or side chain and inorganic nitride particles and containing the inorganic nitride particles in an amount of 0.1 to 20 parts by weight based on 100 parts by weight of the fluorine-containing elastomer. Also the curable composition is one comprising at least one kind of a crosslinking agent selected from the group consisting of an oxazole crosslinking agent, an imidazole crosslinking agent and a thiazole crosslinking agent, a fluorine-containing elastomer having a cure site crosslinkable with the crosslinking agent and inorganic nitride particles.
摘要:
A printer including at least two tractor unit mounting sections upstream of the print position in the sheet feed direction, and at least one tractor unit can be mounted on either of these tractor unit mounting sections. The sheet feeding direction can thus be selected freely in accordance with the web replacement frequency or the printer installation location merely by changing the mounting position of the tractor unit. If the number of tractor units is increased, a plurality of webs can be set up simultaneously and used selectively.

摘要:
A serial printer for printing on a thermosensitive recording medium. The printer includes a frame having a carriage supported thereon for lateral movement across the recording medium. A thermal print head is supported on the carriage for lateral displacement therewith for printing on the recording medium. A platen is supported on the frame for supporting the recording medium so that the print head can be pressed against the recording medium to effect thermal printing thereon. A motor having a relatively flat configuration is supported on the frame and includes a vertical rotatable shaft which is rotated by the motor. A drive gear system is operatively coupled to the rotatable shaft of the motor for selective rotation thereby in opposite directions in response to rotation by the motor. A conversion mechanism converts rotation of the drive gear into lateral movement of the carriage. A paper feed mechanism for feeding the recording medium past the print head and a platen release mechanism for releasing the print head from engagement with the platen are operatively coupled to the carriage for selective actuation thereby.
