    • A satellite signal receiving apparatus including a channel selector, an outdoor unit and a single transmission line connecting therebetween. The satellite signal receiving apparatus has such a simple structure that the installation work thereof is simple. In the satellite signal receiving apparatus, by superposing a pulse train over a source voltage supplied from the channel selector to the outdoor unit, the type of the polarized radiation signal to be output from the outdoor unit as transmission signal is switched. Since no change of the source voltage is required for switching the type of the polarized radiation signal, appropriate source voltage can be supplied to the outdoor unit. Furthermore, since no action against the heat released by a constant-voltage circuit is necessary, the type of the polarized radiation signal can be switched easily. Even if the source voltage varies with the length of the transmission line, the type of the polarized radiation signal can be switched effectively and stably.

    • A satellite signal splitter is proposed which can transmit a received signal of a desired polarized wave with one cable to each terminal side when transmitting to plural terminal sides the received signals from a satellite receiving antenna which emits the received signals of a vertically polarized wave and a horizontally polarized wave.The vertically and horizontally polarized-wave received signals transmitted to input terminals 22V and 22H are split into four by splitting circuits 26V and 26H, respectively. The four split signals are transmitted to switching circuits 28a to 28d. In the switching circuits 28a to 28d, in accordance with a voltage level (11V or 15V) of a polarized-wave switching signal transmitted from terminal units connected to output terminals 24a to 24d, either the vertically or horizontally polarized-wave signal is selected and emitted from the output terminals 24a to 24d. Also, the polarized-wave switching signal (11V or 15V) is transmitted via a voltage synthesizing portion 30, choke coils LV, LH and the like from the input terminals 22V and 22H to a corresponding receiving portion of a receiving antenna.

    • A direction adjustment indicator for a satellite radio wave receiving antenna comprises a demodulating circuit to demodulate a satellite radio wave received by the antenna, a peak holding circuit always to output a held peak value of the demodulated output of the demodulating circuit, a comparator circuit and a display element. The comparator circuit compares the instantaneous value of the demodulated output and the held peak value, and outputs a signal when both values are equal and another different signal when both values are not equal. The display element gives two different kinds of display in accordance with the signals. While the azimuth angle of the antenna is varied in one direction, a peak value of the demodulated output is held and while the angle is varied in the opposite direction, the optimum azimuth angle is displayed for which the instantaneous value of the demodulated output agrees with the held peak value.

    • A vehicle speed sensor is connected to a fluid pressure source such as the engine intake manifold and produces a pressure output corresponding to vehicle speed. An actuator in the form of a diaphragm assembly positions the engine fuel control member in accordance with the pressure output of the speed sensor so as to decrease the amount of fuel for combustion as the vehicle speed increases and vice-versa so that the vehicle speed is maintained at a predetermined value regardless of vehicle load. A normally open exhaust brake valve is provided in the engine exhaust system and is automatically closed to block the exhaust system and thereby brake the engine when the speed control system is energized and the fuel control member is moved by the actuator to a minimum fuel demand position. This condition occurs when the vehicle is rolling downhill or the like and the vehicle speed cannot be limited to the predetermined value by fuel control alone. Various switches are provided to automatically de-energize the speed control system when the operator depresses a brake pedal, a clutch pedal, a manual exhaust brake switch and when the vehicle speed exceeds the predetermined value by a predetermined amount.
