Abstract: This invention provides an apparatus for shaping a spherical body consisting of dough crust and a filling from a continuously fed cylindrical body, consisting of dough crust and a filling, and comprising at least three slidable members which form an opening or closes it. The members slide on each other so as to constrict the cylindrical body. Each of the members has a tapered portion adjacent to an edge formed at the corner where two adjoining side surfaces meet. The edge has a preselected length so that the spherical body with a highly elastic dough crust is shaped without exposing the filling.

Abstract: A remote control device comprises a control input unit, a transmission unit, a receiving unit, a reply unit and a command control circuit. The control input unit outputs a control signal. The transmission unit stores the control signal in a first memory circuit and transmits a light signal based on the control signal. A main device controlled by the remote control unit receives in a first receiver circuit and stores in a second memory circuit the signal from the transmission unit. The main device has a reply signal unit for transmitting a return signal based on the signal from the receiving unit to a second receiver circuit of the remote control device. The command control circuit compares the signal received by the second receiver circuit and the signal stored in the first memory circuit. When these compared signals are in agreement, the command control circuit outputs to the transmission unit a signal based on the signal stored in the second memory circuit thereby to cause the operating device to operate.
