摘要： Door packing (35) having a base (36), a first lip (37), and a second lip (38) is stretched around periphery of a back surface cover (31) of a door (30). When the door (30) is closed, the second lip (38) is inserted into a heating chamber (22), the first lip (37) pivots in directions of arrows (A) once an extremity of the first lip (37) comes into contact with a front face panel (40), and an extremity of the second lip (38) is then brought into close contact with inner wall surfaces of the heating chamber (22). Thus both the front face panel (40) and the inner wall surfaces of the heating chamber (22) are sealed, so that smoke, steam and the like produced by objects to be heated are reliably prevented from leaking out of the heating chamber (22). Besides, condensed water is prevented from accumulating in a groove formed on a border between the front face panel (40) and the first lip (37) while the front face panel (40) is sealed by the first lip (37), and thus the condensed water in the groove is prevented from falling down out of the heating chamber (22) when the door (30) is opened.

摘要： An automatic player piano is equipped with solenoid-operated pedal actuators for driving the pedals in a playback; since a large quantity of induction is coupled to the solenoid, the driving signal is delayed due to long time constant so that the pedals behave differently from those in the original performance; a controller, which is incorporated in the automatic player, firstly determines a target mean current of the driving signal to be theoretically required for the reproduction of the pedal motion, and a temporary means current twice as much as the target mean current at the maximum; the controller supplies the driving signal at the temporary mean current to the solenoid in an early stage of each cycle, and, thereafter, recovers the driving signal to the target mean current so that the pedal motion becomes close to that in the original performance.
