IPC: H01J37/22
Filed: 1989-03-20
Abstract: PURPOSE:To count the true output signal pulses by adjusting the impressed voltage of an ion detector in such a manner that the crest distribution range of the output pulses from the ion detector exists on the higher level side than a noise crest distribution. CONSTITUTION:Secondary electrons enter a collector 3' at every one incident ion from the ion detector 3 and are set as charge pulses through a preamplifier 4 and a main amplifier MA 5 to a discriminator DC 6. The noise of the level lower than the level of the pulse signals corresponding to the incident ions are included in addition to the above-mentioned pulse signals in the signal entering the DC 6 at this time and, therefore, the threshold of the level which is the DC 6 is set and only the signals above the threshold are fed as the true signals for the incident ions to a counter 7. The level of the crest distribution range of the output pulses of the detector 3, however, lowers as the time passes by and overlaps on the level of the crest distribution of the noise to make the sepn. difficult and, therefore, the crest distribution of the MA 5 is monitored 8 and the impressed electric power to the detector 3 is adjusted, by which the high crest distribution is maintained and the exact measurement to exclude the noise is executed.

Abstract: PURPOSE:To avoid the waveform distortion or the like which is caused by the frequency characteristics of the capacity component, by securing an equal input signal voltage between the two input terminals in terms of phase with two impedance components connected to the input terminals of a differential amplifier or by other methods. CONSTITUTION:An input signal source 2, the 1st and 2nd impedance components 3 and 4 plus negative feedback circuits 5 and 6 are connected to the input and output terminals of a differential amplifier 1 as shown in the diagram. Then the input signal voltage in which the negative feedback voltage is superposed on the signal source voltage is made equal between a nonreverse input terminal and a reverse input terminal in terms of phase by the components 3 and 4. For instance, the output voltage and the internal impedance of the source 2 are referred to as Vi and Zi respectively, the impedances of the components 3 and 4 are Z1' and Z2, and the internal resistance of the negative feedback circuit is Rbeta. Thus the following relation is satisfied: Vi=k1.(Zi+Z1')/(Z2+Rbeta), where k1 is the proportion constant.

CONSTITUTION:When the headlamp light A1 of the succeeding car enters into an inter-car distance warning reflector 5 at an angle smaller than a critical angle theta against the refraction surface 1c of a refraction plate 1, it is reflected by a reflection sufface 2 in the reverse direction by 180 deg. in a locus of A1 A7. Furthermore, the light B1 entering at an angle larger than the critical angle theta is rflected as B3 and is absorbed into a non-reflection surface 1d. The inclination of the refraction surface 1c is set so that this critical angle theta is made an angle formed by the headlamp light entering from an inter-car distance warning starting point O to the succeeding car and the normal line P to the refraction surface 1c. Thereby, a dangerous inter-car distance during the night travel can be informed of to the succeeding car by means of the reflection of the headlamp light.

Filed: 1987-03-24
Abstract: PURPOSE:To shorten the time required for a preview by measuring a servo locking state every time the preview is performed and controlling the rewinding amt. of a magnetic tape in accordance with the result of the measurement. CONSTITUTION:At the time of previewing a player, an editor 2 outputs a control signal SC4 to display a black display screen on a monitor 7, and then outputs a control signal SC1 into a VTR 3 for output reproducing to rewind its tape from a cut-in point by a prescribed amt. As a result, the tape position is shifted to a preroll point PPRE. And now, the editor 2 changes the VTR 3 over to a reproducing mode, and consequently, the tape position TP in the VTR 3 is gradually approached to the cut-in point CIN. Furthermore, when the VTR 3 is servo locked, the editor 2 receives a bit of servo information SD from the VTR 3 and measures how many frames have been servo locked continuously by the VTR 3 during the traveling time of the magnetic tape from the point PPRE to the check point PCH, and then learns the preroll time based on this measured value.
