A reflected signal from a target is received by the antenna 4 and detected by a mixer 5, and it is correlated with a code of one bit before and behind a transmission wave by correlators 16a and 16b. Each correlation output is sent to Doppler filter 7a, 7b, a component of a pure relative speed difference from the target is obtained in an output of a comparator 9, a quadrant wherein the target located is discriminated by AND circuits 18a-18d, and ignition circuits 10a-10d corresponding thereto are operated. In this way, detection of the use of a wave and the effect of jamming are prevented substantially and thereby a range of operation can be made definite.

IPC: G03G21/00
Filed: 1988-12-14
Abstract: PURPOSE: To remove residual toner and 'dust' from a photoreceptive surface by making a rotary brush type cleaning device composed of an electrically biased cleaning brush and a toner removing means and providing the toner removing means in the vicinity of the vibration node of the brush generated when separation from the photoreceptive surface is attained. CONSTITUTION: The fiber cleaning brush 100 is supported so as to rotate in the direction of an arrow 102 in a cleaning housing 106 by a motor 104 and negatively biased by a DC power source 108. Then, the residual toner and a contamination, that is, the 'dust' such as paper powder and kaolin are removed from the photoreceptive belt 10 by the rubbing work of cleaning fibers 110 against the belt 10 and the work of an electrostatic charge applied to the cleaning fibers from the DC power source 108. Then, the brush fibers 110 have tendencies to vibrate, while being damped some, after the fibers 110 are free from contact with the belt 10. Thus, the fibers work for repelling toner and the 'dust' from the brush, at a converged node place, so that when a first toner removing roll 114 is arranged in close proximity to the position, repelled matter can be collected.

The delayed phase is obtained with an edge detecting circuit 34. A reset signal R (i.e., an output signal A3 of a circuit 34) is imparted to a peak holding circuit 36 at this timing. When the signal R is imparted, the circuit 36 resets the peak value, which has been held up to this time. The peak value at this time is newly sampled. The sample value C corresponds to a thickness (t) of a bottle. The value C is imparted to an operating circuit 28 (V is an actual output voltage, and V0 is an initial output voltage). A signal D of the corresponding thickness (t) is outputted by a specified expression in a frame.
