Abstract:
There is provided a highly reliable transmission/reception integrated radio-frequency apparatus which can achieve a high communication quality in a cable modem. A reception RF signal is input to a reception system block via an input/output terminal, converted to an intermediate-frequency signal, and output from a terminal. An output terminal of a transmission processing section of a transmission system block is connected to the input/output terminal via an overvoltage protection circuit, a high-pass filter functioning as a countermeasure to overvoltage, and a low-pass filter for suppressing harmonics produced from the high-pass filter.

Abstract:
A variable length code recording/playback apparatus, which by encoding intra-frame data and inter-frame data in variable length code, records them as recorded codes on prescribed locations of tracks of a recording medium and plays them back, which includes a data rearranger for recording the data in areas to be played back at least two specific speed mode playbacks on the tracks by rearranging prescribed data out of the data encoded in variable length code, a variable length decoder for playing back the data recorded on the recording medium and decoding it in variable length code, a data restorer for controlling and restoring the time series of the output of the variable length decoder to the original data train before the rearrangement, and a decoder for constructing a playback picture from the decoded outputs for several frames in the specific speed mode playback by decoding the output of this data restorer.
Abstract:
A recording/reproducing apparatus for a data packet stream having an extractor for extracting data packets of a selected type from an input packet train in which different types of data packets have been time-division multiplexed together. The apparatus also has a recording circuit for recording the extracted data packets, and a reproducing circuit for reproducing the recorded extracted data packets. A dummy packet producer, which produces dummy packets that correspond to data packets that have not been extracted, is also provided. Further, the apparatus has an output circuit that outputs an output data packet train. The output data packet train is produced by combining the reproduced extracted data packets and the dummy packets in accordance with the order in which the different types of data packets are positioned within the input packet train.
Abstract:
A cooking apparatus such as a rice cooker includes means for obtaining a value or a combination of values indicative of an amount of food that is to be cooked, and a fuzzy inference section for operating on that value or combination of values to determine a level of heating power to be supplied to a heater element of the apparatus, during at least one part of the cooking process. The amount-indicating value can be obtained for example as a rate of change of temperature of the food while it is being heated to boiling point. The apparatus can further be configured to determine a plurality of cooking control parameters, by fuzzy inference operation, based on a specified degree of final hardness of the cooked food, which can be selectively inputted by the user.
Abstract:
The washing machine controller has a cleaning sensor, a variation detecting device, a time counter, a washing time inference unit and a control unit. The cleaning sensor detects a turbidity of water in a washing tub of the washing machine. The variation detecting device detects a variation of the detected turbidity. The time counter measures a saturation time period, from a start of washing operation to a time point of saturation. The time point of saturation is determined when the detected turbidity becomes less than a predetermined value. The washing time inference unit uses a fuzzy inference operation to make an inference as to an additional washing time necessary for the cleaning operation after the time point of saturation based on the saturation time period and the detected turbidity. The fuzzy inference operation incorporates human experience in to the washing time determination process. The control unit stops the washing operation when the additional washing time expires.
Abstract:
A control circuit for an air cleaner including a gas sensor, an ultraviolet sensor and a control circuit for performing an automatic operation of the air cleaner in response to the detection of outputs of the sensors. A predetermined number of electrical pulses from the ultraviolet sensor are observed by the control circuit during a first predetermined time period after the passage of a second predetermined time period from a point of time when an initial pulse from the ultraviolet sensor has been inputted to the control circuit, the control circuit identifies the predetermined number of the pulses as a drive signal for initiating the operation of the air cleaner.
