Title: Multiple feed detector
Inventor: TSUKADA MASAHARU
IPC: G01B11/06
Filed: 1981-11-20
Abstract: PURPOSE:To securely detect multiple feed of conveyed paper regardless of the kind of the paper by storing a signal corresponding to the thickness of paper to be conveyed a specified time after the front end of the paper is detected, and comparing and monitoring said signal and paper thickness signal. CONSTITUTION:Fed sheets of paper 30 are conveyed with their tip shifted. When the front endIof paper passes through a paper detection part 36, a voltage (a) drops owing to the attenuation of the quantity of transmitted light by the paper and the output of a comparator 32 varies from H to L. A pulse generator 35 generates an output a specified time (t) later at timing corresponding to a point II where the detection level of the 1st sheet of paper is stabilized, thereby operating a sample holding circuit 33. A reference value VT is obtained from the stored value and regarded as the threshold value of a comparator 34. When double conveyed paper at a point III passes through the paper detection part, the voltage (a) further drops are the comparator 34 outputs a detection signal.

Filed: 1989-07-21
Abstract: PURPOSE:To obtain high resolution in the whole phosphor screen from low to high electric current by using quadrupole lens as prefocusing lens besides a main lens composing an electron gun. CONSTITUTION:A first focusing electrode 30 is set in an accelerating electrode 20 side and a second focusing electrode 40 is set in an anode 50 side where the first and second focusing electrodes compose an electron gun, and an astigmatism collection system to modulate cross-section shape of electron beam is installed in the opposite to both focusing electrodes 30, 40. Voltage modulated to be higher level than focus voltage of the first focusing electrode 30 corresponding to deflection of electron beam is applied to the second focusing electrode 40 so as to provide a function to the first and the second focusing electrodes 30, 40 to form the cross-section shape of the electron beam to be long in the vertical direction. Together with that, horizontally long slit grooves 24-26 which surround three electron beams are formed in the first focusing electrode side 30 of the accelerating electrode 20 which composes prefocusing lens. That is, a quadrupole lens is formed with parallel plates (vertical plates) sandwiching an electron beam passing hole of the first focusing electrode 30 and parallel plates (horizontal plates) of the second focusing electrode 40. As a result, high resolution in the whole phosphor screen is obtained from low to high electric currents.

Abstract: PURPOSE:To improve the gain reduction in the low band part of the high frequency band and to reduce the degradation in sensitivity by directly supply in the output signal of a tuning circuit to the circuit in the next stage at the time when the high frequency band is the tuning object band. CONSTITUTION:At the time of reception of the high frequency band, 12V and 0V are supplied to switching terminals 13 and 14 respectively.

In case of l>s, the size (s) is doubled by a multiplier 21, is then applied to a comparator 23, and is supplied to a latch circuit 25 via an adder 24. Then, the subtractor 19 which receives the number (s) of shots produced and the integral value ns produces an output obtained by subtracting the pattern size (l) by the ns to the comparator 23. In case of 2s<l-ns, the output (l-ns)/2 from a divider 20 inputted to a gate circuit 26 in case of 2s>l-ns is outputted from the gate circuit 26. In case of 2s>l-ns, the output of the register 17 is produced from the circuit 26. At this time the beam position output is formed by adding the output of the circuit 25 and the pattern start position to the adder 27.
