Filed: 1985-11-01
Abstract: PURPOSE:To provide a light emitting and receiving function by placing two polarizing prisms opposite each other, splitting unpolarized input light into two, and utilizing the reflection of an S polarized component by the polarizing prisms. CONSTITUTION:The polarizing prisms 2a and 2b are arranged so that their polarizing films face each other; and the prism 2a is used for light reception and the prism 2b is used for light transmission. Received light Ro transmitted through an optical fiber cable is split by the prism 2a into a P polarized component RP and an S polarized component Rs; and the component Rp travels straight in the negative direction of a (y) axis and the component Rs travels in the (x)-axial direction. The component Rs incident on the prism 2b is reflected by the polarizing film to travel in the (y)-axial direction. Half of transmitted light To incident on the prism 2b along the (y) axis, on the other hand, travels straight as a P polarized component Tp when a light source is in a nonpolarization state and the S polarized component Ts is reflected and discarded. When the light source in a single polarization state, the light source is so arranged as to perform P polarization, and then nearly all of the light To becomes a component Tp as it is.

Abstract: PROBLEM TO BE SOLVED: To make a device for detecting speed of vehicle withstand disturbances and interference by eliminating the influence of the multiple paths on the device. SOLUTION: A device for detecting speed of vehicle is provided with two antennas 1 and 2 which radiate radio wave beams by performing spectrum spreading and receive reflected waves, a correlator 35 which specifies the distance between gates passed through by a vehicle based on the time representing the peak value obtained by reversely spreading the modulated signals of received signals, a code generator 37 which generates a code sequence at a fixed speed, a bit delaying section 38 which specifies the distances from the antennas 1 and 2 to the gates by delaying the code sequence used by the correlator 35 for reversely spreading the received signals, and a Doppler filter and amplifier 36 which only extract a Doppler frequency component.  A speed computing section 9 calculates the time difference between the time when the vehicle passes through one gate and the time when the vehicle passes through the other gate and, when the vehicle exceeds the speed limit, finds the Doppler speeds of the vehicle with respect to the two radio wave beams and averages the speeds.

Filed: 1987-09-30
Abstract: PURPOSE:To correctly and stably execute the lead-in of a focus by operating a focus control means just after a detecting means detects that a light beam on a recording carrier is made into a prescribed converging condition. CONSTITUTION:At the time of starting the lead-in of the focus, a convergent lens 5 is approached to a disk 7, a focus position is located to an upper part than an information carrier surface, the convergent lens 5 is lowered from the position, the loop of a control system is closed at a point where the focus position passes the information carrier surface slightly, and the focus is led in. Consequently, since a first surface to appear in a focus dislocation signal at the time of distancing the convergent lens 5 is the information carrier surface, a focus lead-in level can be made small regardless of the intensity of the focus dislocation signal, and the information carrier surface can be correctly detected. Since the focus lead-in level can be made small, the focus control is operated very in the vicinity of the information carrier surface. Thus, the lead-in of the focus control can be correctly and stably executed.
