An apparatus and method for storing digital broadcast data in a digital broadcast receiving terminal. If the digital broadcast receiving terminal enters a weak electric field strength region during reception of digital broadcast data, digital broadcast receiving terminal stops the process of receiving the digital broadcast data so as to check whether digital broadcast receiving terminal re-enters again into the strong electric field strength region. Then, if the digital broadcast receiving terminal re-enters the strong electric field region, the terminal shifts a TS value of a received digital broadcast data frame to the value obtained by adding a frame interval of the digital broadcast data frames to the TS value of the previous data frame that had been completely stored just before the digital broadcast receiving terminal entered the weak electric field strength region. Thus, the invention enables the digital broadcast receiving terminal to drop the digital broadcast data frames received during the weak electric field strength intervals so that it may smoothly and continuously play back the digital broadcast data frames received only during the strong electric field strength intervals.

Provided is a function of providing a recordable time considering remaining memory capacity. To implement this function, an average reception rate of broadcasting data received for a predetermined time (e.g., several seconds) is calculated, and the recordable time is calculated using the calculated average reception rate and the remaining memory capacity. By doing this, even if the amount of broadcasting data to be recorded varies according to broadcasting programs, the amount of broadcasting data to be recorded can be predicted, and thereby, a user can efficiently record a desired broadcasting portion by actively determining whether the broadcasting is recorded.

A power transistor driving circuit for a single power source drives a predetermined load and prevents each of the drive circuit transistors from being damaged because they are not turned on simultaneously.

Power-transistor driving circuit for a single power source

A power supply circuit interrupts power to a load in response to a short-circuit or an open-circuit condition and automatically restores power after a momentary short-circuit. A short-circuit detector monitors the current flowing through the load and generates a short-circuit signal if the current exceeds a predetermined level. An open-circuit detector monitors the load voltage and generates an open-circuit signal if the voltage exceeds a predetermined level. A latch converts the short-circuit signal to a latch signal. A logic unit combines the latch signal with the open-circuit signal and a pulse signal from a pulse generator to generate a drive signal. A driver uses the drive signal to control a switch which is connected between the power source and the load to interrupt power to the load. During a short-circuit, a timer generates a periodic pulse signal that toggles the latch signal and intermittently restarts the power to the load. If the short-circuit was of short duration, power is restored to the load. If the short-circuit persists, the power supply circuit continues to intermittently restore power to the load until the short-circuit is removed. The logic unit also generates a fault signal in response to the latch signal and the open-circuit signal. A display unit generates a visual alarm in response to the fault signal to indicate an abnormal state.

Power supply circuit with load protection function

A motor control circuit comprises a current command circuit generates a current command signal proportional to a selected motor speed. A comparator generates a comparator output signal proportional to the difference between the current command signal and a signal proportional to current flow in the motor. An output terminal of the comparator is operatively connected to a logic circuit which generates a control signal having a duty cycle that varies proportional to the comparator output signal. A drive circuit has an input terminal to which the control signal is applied and an output terminal connected to the motor. The drive circuit generates a motor drive signal proportional to the control signal for driving said motor. A current command control circuit has an input terminal to which the current control signal is applied and an output terminal to which the current command signal is applied. The current command control circuit generates a signal proportional to the control signal and reduces the current command signal when the proportional signal is less than the current command signal.

A system for controlling an automobile cooling fan utilizes a temperature-sensitive negative resistance device having a resistance which decreases as the temperature rises, and which increases as the temperature falls. Thus, if the cooling water temperature does not exceed a certain level, the cooling fan motor is not driven. If the temperature exceeds a certain level, the cooling fan motor is driven in proportion with the dynamic temperature variations. Therefore, a variable cooling fan speed is possible, and therefore, the cooling operation becomes efficient.
