Title: Differential amplifier circuit
Inventor: MIKAMURA YASUKI
IPC: H03F3/45
Filed: 1993-11-29
Abstract: PURPOSE:To improve the band characteristic by adding a capacitive element between a common source of a differential input FET and a power supply and connecting a common source to ground in terms of AC so as to prevent a deterioration of gain even in the case of single phase input configuration. CONSTITUTION:FETs 100, 101 form a differential FET pair and a power supply 51 is connected to its common source via a current source FET 102. Then a capacitive element 400 is connected between the common source and the power supply 51. This causes connection of the common source to ground in terms of AC, and gain deterioration is prevented and a band characteristic is improved to enhance the general-purpose performance of the differential amplifier circuit even when the differential amplifier circuit is operated as a single phase input configuration by selecting the capacitance of the capacitor.

Title: Diaphragm controller for camera
Inventor: FUJIMOTO KOICHI
IPC: G03B7/10
Filed: 1990-11-01
Abstract: PURPOSE:To always make the lightness of background constant by deducting an optimum stop value based on calculated in-pattern brightness means value, in-pattern brightness variance, and interplural-pattern mean brightness variance and controlling the diaphragm of the camera based on the result of deduction. CONSTITUTION:An image pickup signal fetched from a TV camera 1 is converted into a digital signal an A/D converter section 3 and stored in a picture memory 4. An arithmetic section 5 calculates in--pattern brightness mean value and in-pattern brightness variance based on the data stored in the picture memory 4. A deduction section 6 receives the in-pattern brightness means value, in-pattern brightness variance and inter-plural-pattern mean brightness variance to execute fuzzy deduction and outputs a camera stop value deviation. That is, a deviation to obtain an optimum stop value respect to a current stop value is outputted and a diaphragm of a lens 2 is controlled at a voltage level through a D/A converter section 7 based on the deviation. Thus, an input picture with an optimum brightness based on the back ground is always obtained and even when the entire illuminance changes outdoor, an optimum picture close to a picture observed by human eyes is obtained and the processing such as binarizarion is simplified.

Filed: 1989-11-15
Abstract: PURPOSE:To prolong the life of a light emitting tube, to improve exposure for a high- sensitivity film and the depth of focus in a short distance and to enhance automatization by using a strobe light quantity control means, making a GNo value constant and controlling an FNo value in the short distance and making the FNo value constant and controlling the GNo value in a long distance. CONSTITUTION:It is desirable to make the GNo expressing the emitted light quantity of a stroboscope 5 as small as possible from point of view on the life of the light emitting tube because energy in proportion to the square of the GNo is consumed. Meanwhile, it is desirable to make the emitted light larger, a stop value FNo smaller and the depth of field deeper as the distance becomes shorter in an identical lens. Therefore, according to the information on film sensitivity the GNo is made constant and the FNo is controlled in accordance with distance information on the closest distance side in the case of setting a certain distance as a boundary, and the FNo is made constant and the GNo in accordance with the information on the film sensitivity is switched from the constant value to a maximum value so as to control the light quantity according to the distance on a far side so that energy loss is reduced, appropriate exposure is easily obtained and a manual operation is made needless because of the automatization.

IPC: G11B15/467
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To simplify the structure and to enable high precision tracking control even in a narrow track by detecting only a pilot signal recorded in one adjacent track out of the two adjacent tracks so as to perform the control. SOLUTION: At the time of reproducing, odd-numbered tracks and even- numbered tracks 11 to 17 and 12 to 18 are alternately scanned by heads 21 and 22 positioned opposite to each other at 180 degrees in repeating the 1st-4th scanning of 11 to 14 and then 15 to 18 as one set. A signal j outputted from a detector 3 by detecting an amplitude of a P1 pilot signal contained in a regenerative signal i is turned into a signal k by an S & H 4, and this is changed by a selecting polarity inverter 5 with a polarity signal r. A ripple of a frequency for making the round of the track is removed from an output signal l of the inverter 5 by a filter 7 to output an error signal h, and AFT control is performed by a controller 8 with the signal h.  Thus, by simple constitution, the pilot signal is selected to meet the optimum fringe amt. of the head, and even a narrow track can be controlled with high accuracy.
