Title: Electronic shutter driving method for solid-state image pickup device
Inventor: MATSUNAGA MASAYUKI
IPC: H04N5/335
Filed: 1987-02-25
Abstract: PURPOSE:To enlarge a vertical resolution by reversing the magnitude relation of respective signal storage times situated at the odd number line and at the even number line of a light receiving storage part, for every adjacent field. CONSTITUTION:In a first field, in terms of the output of a stored signal charge, since the signal storage time t1 of the odd number line > the signal storage time t2 of the even number line, the output of the odd number line is larger than that of the even number line. In a second field, on the contrary to the first field, since the signal storage time t1 of the even number line > the signal storage time t2 of the odd number line, the output of the even number is larger than that of the odd number line. Thereby, the vertical resolution is higher than the conventional driving method in which the signal storage time t1=the signal storage time t2.

Title: Semiconductor laser drive circuit
Inventor: ERA YOSHIKAZU
IPC: H01S5/06
Filed: 1987-02-27
Abstract: PURPOSE:To make the degradation of the output light waveform vs. the amplitude variation of an input signal small by applying the upper clamping to the input signal of a GaAs FET for driving a semiconductor laser. CONSTITUTION:The relation of the gate voltage of vs. the drain current of a GaAs FET 2 is that of a quadratic curve, and particularly when the gate voltage is in the neighborhood of the pinch-off voltage, the quadratic curve makes a large curve downwardly. Thus, when the amplitude of an input signal applied to the gate terminal of the FET 2 for current drive varies, the maximum value of the input signal voltage is fixed by a clamp circuit 5 and the lower part thereof is varied. With this, as compared with the case where the upper and lower parts of the input signal voltage are varied, the driving current of a semiconductor laser becomes less variable, whereby the deformation of the light output waveform due to the driving current variation becomes small.

Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To enable bank notes of different sizes to be efficiently separated and processed by providing a control means for temporarily suspending a supply roller when the detection signals are input continuously from a bank note detection means over a specified time. SOLUTION: When bank note detection signals to be input from a sensor 19 is input over the time required for detection of bank notes of the maximum length to be processed, a CPU judges that two or more bank notes are laminated and sent and is difficult to separate and temporarily suspends a supply roller 16 for a specified time via an electromagnetic clutch and an electromagnetic brake. As a result, for the preceding bank notes, the back end part thereof has already passed the clearance between the supply roller 16 and a carrier roller 18a, therefore, only the preceding bank notes are carried to the downstream side by means of a high-speed rotation carrier roller 23a, and bank notes can be separated certainly one by one.  If the sensor 19 does not detect the supply bank notes from a bank note entry part one by one, the CPU outputs driving signals and restarts ordinary bank note processing.

Abstract: PURPOSE:To detect even a small press down amount accurately by averaging the plate thickness data sampled on the inlet side of a mill and extracted on the outlet side thereof thereby determining an achieved value of plate thickness on the outlet side. CONSTITUTION:A measurement timing signal generating section 32 receives a rotational speed detection signal 31 of a motor 25 and delivers timing signals at times T1 and T2 to a plate thickness data memory section 33. Plate thickness on the inlet side of a mill is detected by a thickness gauge 18 and sampled 33 during a time interval T1-T2 thus storing (m) 33 plate thickness data. The generating section 32 also operates the time required by a member 1 to be rolled for passing between the thickness gauges 18, 28 based on the peripheral speed of a work roll 12 according to a predetermined formula. Furthermore, outlet side plate thickness measurement timings T3, T4 are determined and delivered to a plate thickness data memory section 34. Outlet side plate thicknesses detected by the thickness gauge 28 during a time interval T3-T4 are sampled 34 and (n) plate thickness data is stored 34. A plate thickness operating section 35 receives the plate thickness data thus stored 33, 34 and determined correlation coefficients of plate thickness data between inlet and outlet sides and then extracts the maximum value thereof. Average values HAV, hAV of plate thickness on the inlet and outlet sides are then determined according to a predetermined formula.
