  • Patent number: 6028297
    Abstract: A rice cooker does not cause malfunction if the operation unit is touched by mistake when closing the lid, and is capable of preventing boil-over without lowering the rice cooking performance. The rice cooker includes a main body, a lid for covering the top of the main body, an inner pan detachably accommodated in the main body, a heater for induction heating of the inner pan, a controller for controlling the supply of high frequency power to the heater, an operating unit, and a lid opening and closing detector or a rice gruel detector disposed in a steam tube of the lid. The controller inhibits operation signal input of the operating unit when detecting an open state of the lid, and controls the power supply to the heater when detecting a rise in the rice gruel. Therefore, the rice cooker prevents a wrong input in rice cooking when opening or closing the lid, and prevents boil-over of the rice gruel.

  • Patent number: 5744741
    Abstract: A plurality of digital signal processors are provided in parallel relation to each other, and a series of operations for desired sound signal synthesis or processing is divided into a plurality of operation groups to be allocated to the signal processors. First and second buses are connected to each of the signal processors so that parameters necessary for the operations are distributively supplied to the signal processors via the first bus and the operation result of each of the signal processors is transferred to another digital signal processor or an output port via the second bus. One digital signal processor receives the output data from another digital signal processor via the second bus so as to perform a predetermined operation using the received data. The desired sound signal processing is thus executed by combinations of the operations performed by such signal processors.
