Patent CA-1302524-C (CA)
Inventor: PARLY DIDIER
IPC: H03L1/02
Filed: 1988-05-19
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE     A temperature-compensated  piezoelectric oscillator of high-spectral   purity,   capable  of  being  controlled  in frequency,  consists of a compensation circuit, a processing circuit,    a   phase-shifting   circuit,   containing   the piezoelectric  resonator,  and  an  oscillating  circuit. To obtain  high  spectral  purity,  it  is  proposed  to  use a low-pass  filter,  placed  between  the compensation circuit and one  of  the  inputs  of  the  processing  circuits, to process  the  signal  coming  from the compensation circuit.          This  filter  eliminates  the  influence  of the temperature noise  coming  from  the compensation circuit. The invention can   be  applied  to  controllable  frequency,  temperature compensated  piezoelectric  oscillators  where high spectral purity is sought.

There is also provided a second sensor to detect that the connector is located at a position adapted to   come into contact with the contacts of  the IC card on the basis of  the motion of  the supporting member.   The supporting member has a projecting portion adapted to abut on the IC card which has overrun from the predetermined position.  When the projecting portion abuts on the IC card, no detection signal is output from the second sensor.

Abstract: Electrically powered trolley vehicles in headings of mines are provided with a current collector pick-up unit having contact-sensing means, current collectors, position sensors and guide wheels. The power supply for the pick-up unit comprises an array of elongated guide rails and at least two conductor bars. The connecting method comprises running the vehicle slowly forwards, by means of its own energy source, in the direction of the elongated conductor bars and vertically raising the pick-up unit by means of an arm mounted on the vehicle so that a contact-sensing frame for sensing contact in a vertical direction is brought into engagement with one or both of the guide rails. During a continued vertical movement, the contact-sensing frame is turned down towards the rest of the pick-up unit and when the contact-sensing frame reaches its lower end limit position, this is indicated by a position sensor. The pick-up unit is then turned in the lateral direction until contact-sensing bars for horizontal sensing are brought into engagement with the nearest guide rail. When the position sensors indicate this, the frame is lowered and the pick-up unit with its current collectors and guide wheels is raised towards the conductor array, whereby the current collectors are brought into contact with the conductor bars and the guide wheels are brought into contact with the guide rails.
