Abstract: A video signal selection circuit capable of reading automatically the connection state of a plurality of video jack ports and selecting only modes corresponding to video ports which presently have a jack connected thereto. This video signal selection circuit includes a predetermined number of video jack ports, a predetermined number of switches respectively connected to the video jack ports and turned on when a corresponding jack is connected to the video jack port, and a micro-processor which registers the fact that the jack is connected to the video jack port by checking whether the corresponding switch is turned on. The micro-processor outputs a control signal so that the selection circuit selects only those ports to which jacks are connected when a mode conversion key is actuated. A switching portion is controlled by the micro-processor's control signal and selects for output only those video signal sources corresponding to the control signals received from the micro-processor.

Abstract: A programmed recording device for a VCR without a tuner and a method thereof are disclosed. In the programmed recording device, a microprocessor outputs a control signal when carrying out a recording or a playing, and voltage converting means converts the contorl signal of the microprocessor to a voltage. A voltage detection section detects the voltage after receipt of the output of the voltage converting section, and power source switching means are operated by the power source and in according with the voltage detected by the voltage detecting means. A constant voltage circuit converts the AC power source to a constant DC voltage in a state interlocked with the power source switching section in order to activate the TV. According to the present invention, a recording can be started and terminated at the preset time automatically even without a tuner thereby improving the performance of the products.

Abstract: A device for changing the rotation of a drill from a forward to a reverse direction which comprises a drill, an AC single-phase motor operatively connected to the drill for driving the same, a circular measuring plate connected to the drill, the circular measuring plate having a handle, and a groove disposed on the periphery of the plate, and a microswitch containing electrical terminals and being operatively connected to the motor, the microswitch containing a bar which is pivotally disposed to engage and disengage the microswitch, the bar having a spring biased arm which extends from the microswitch to slidably engage and rotate with the periphery of the measuring plate, whereby when the handle of the measuring plate is rotated in the left or right direction, the bar of the microswitch is caused to move in a corresponding upward or downward direction along the periphery of the measuring plate, until it engages the slot whereby the direction of rotation of the motor is reversed.

Abstract: The switching device of the present invention electrically connects a single-phase induction motor's starting winding to the motor's circuitry upon start-up, and disconnects it once the motor reaches a first predetermined speed. If the motor's speed drops below a second predetermined speed, the switching device reconnects the starting winding to the motor's circuitry until the motor again reaches the first predetermined speed. At start-up, diode bridge D1 turns ON, turning ON SCR S2. With the SCR ON, the diode bridge is short-circuited, drawing a large current through the bridge's a.c. side. This current flows through resistor R8, and the voltage drop across R8 is large enough to turn triac S1 ON. Thus, current flows through starting coil L2. When the motor reaches a first predetermined speed, the voltage across the starting coil is large enough to turn NPN transistor TR2 ON, turning PNP transistor TR1 ON. Accordingly, the SCR turns OFF, eliminating the large current drawn through the a.c.

Abstract: A motor starter and protection circuit is disclosed wherein a bimetallic contact support supports moveable contacts which are electrically interconnected with stationary contacts during normal non-overload conditions. Current from the power support passes through the stationary moveable contact sets as well as the bimetallic contact support and through the main coil of the motor. A positive temperature coefficient resistance is mounted on the contact support in electrical interconnection therewith. Current passes through this resistance, a TRIAC, and the motor starting winding. Conduction of the TRIAC is controlled by sensing the current which passes through the main motor coil. Only when the current passing through the main coil is substantially greater than normal load current is the TRIAC gated into conduction. A phase control capacitance is interposed between the coil sensing current through the main coil of the motor and the TRIAC gate.
