Abstract: A method for detecting and limiting an earth fault current in large on-board power generating systems and vehicle power generating systems, whereby a plurality of generators supply the network via in each case one associated generator protection circuit breaker. A single-phase transformer is provided with an earthed primary winding in the star point line of each generator and with a resistor on the secondary side which tolerates a limited current in the event of a total earth fault. In order to avoid the use of external voltage sources: a. a full-wave rectification of a detected earth fault current is carried out on the secondary side, b. if a current limit which can be set is exceeded, the rectified earth fault current is pulsed at a fixed frequency, c. the earth fault current modulated at the clock frequency is detected on the network and star point side in each phase of the generators, d. the earth fault current detected on the network and star point side in each phase are compared with one another, and e. a generator or the phase of the generator, in which an earth fault has occurred or the network is determined as having an earth fault on the basis of the comparison. <IMAGE>

Abstract: In a vehicle anti-skid hydraulic braking system of the pump/re-apply type the pump plunger (10) is of differential outline and works in a stepped bore (13). An annular chamber (18) and a full pump chamber (19) are defined in the bore (13) on opposite sides of the head (11). The annular chamber (18) is pressurised by fluid at a pressure dependent on the difference in pressure between the master cylinder (29) and the brake (31), and the chamber (19) is subjected to the pressure in the annular chamber (18) in one direction and the pressure in the master cylinder (29) in the opposite direction. The system is therefore provided with a pump (10) which forces fluid back to the master cylinder (29) but with torque levels similar to a pump which acts against brake pressure. In motor cycle installations a unit comprising the modulator assembly (2) and pump (3) is utilised, the unit being sufficiently small to fit into and to be driven by an enlarged wheel hub.

Abstract: A coordinate input apparatus comprises: a vibration pen to generate a vibration; a vibration propagating plate to propagate the vibration generated by the pen by touching the pen to the plate; vibration sensors to detect the vibration propagated to the plate; a supporting member which supports the plate and whose vibration propagating velocity is slower than the plate; a position coordinate calculating circuit to calculate the position coordinates of the pen on the plate on the basis of the detection signals from the sensors; and a display which is provided below the supporting member and displays the calculated coordinates. The plate is made of metal or transparent glass and the supporting member is made of a transparent synthetic resin. The supporting member is directly come into contact with the plate by a rough surface, its acoustic impedance value is different from the plate, and its vibration attenuation ratio is larger than the plate. Since the vibration wave component propagated to the sensors is not influenced by the interference of the vibration propagated in the supporting member, the coordinates can be accurately detected on the basis of the vibration detection waveforms without a distortion.

Abstract: In a switching circuit formed as an integrated circuit, a series circuit oomprising a diode (D₁) and a resistor (R₁) is connected between a base and an emitter of an npn transistor (TR₁) requiring a high speed switching operation. Therefore, a high speed operation is made possible. Furthermore, in a circuit constructed such that the above npn transistor is driven by a pnp transistor (TR₃, TR₄), a leakage current produced in the above pnp transistor at high temperatures is allowed to flow in the above series circuit. Accordingly, a malfunction of the above npn transistor is prevented. Consequently, an integrated circuit operable even under high temperatures is achieved.
