Title: Method and device for detecting man based on differential image
Inventor: ISHIKURA HISASHI
IPC: G06T7/20
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To detect a pedestrian on a dark road at night through the use of an inexpensive image pickup means by detecting moving objects from the difference of images obtained at prescribed intervals and extracting the longitudinal object among them. SOLUTION: The image converted into a digital signal is stored in a frame memory 5 at prescribed time. The image stored in the frame memory 5 is transferred to a frame memory 6 after Ts seconds from that time and the image which is newly inputted is stored in the frame memory 5. A difference axithmatitc operation part 7 obtains the absolute value of the difference between the image stored in the frame memory 5 and the image stored in the frame memory 6. A binarization part 8 binarizes the differential image which is thus obtained and a part changed within time Ts is displayed whitely. A longitudinal object extraction part 10 extracts the object whose length of a longitudinal direction against the width of the white part is more than a prescribed value and the object moving in a lateral direction is judged to be the man.

Title: Phase control system
Inventor: YOSHIDA ATSUSHI
IPC: H03L7/093
Filed: 1988-07-27
Abstract: PURPOSE:To effectively suppress a phase jitter over a wide range with a minimum hardware by counting the frequency of phase jitter resulting in switching the operation mode. CONSTITUTION:When a comparator 113 decides that the frequency of phase jitter is larger than a prescribed value, a selector 114 selects a loop coefficient K2 and also closes the switch 115. Since a predictive filter 109 is operated, the phase jitter is mainly suppressed by a phase rotating device 102. Moreover, when the comparator 113 decides that the frequency of phase jitter is lower than a prescribed value, the selector 114 selects a loop coefficient K1 and also opens the switch 115. Thus, the predictive filter 109 is inoperative and the phase jitter is suppressed by the phase rotating device 101.

Title: Mechanism for preventing misinsertion of different disk case
Inventor: OTSUKA YASUO
IPC: G11B19/04
Filed: 1987-07-27
Abstract: PURPOSE:To prevent the minisertion of a 86mm floppy disk (3.5'' FD) case by combining an optical disk case having a notched part on the opposite side of the 3.5'' FD case to be a different case with a case insertion part having a stopper opposed to the notched part. CONSTITUTION:The notched part 105 on the case 100 is positioned on the opposite side to that of a 3.5'' FD case and the case insertion part 200 is provided with the stopper 201 opposed to the notched part 105. When the case 100 having the notched part 105 is inserted into the case insertion part 200, the case 100 is loaded to a correct position without being contacted with the stopper 201. When a different case such as a 3.5'' FD case is inserted, the side end part 110 is abutted upon the stopper 201, so that the case can not be inserted. Consequently, the different case can be prevented from being inserted in error.

Title: Variable gain circuit and integrated circuit therefor
Inventor: KASASHIMA MASAAKI
IPC: G06G7/12
Filed: 1994-08-08
Abstract: PURPOSE:To provide a gain conversion circuit suitable for a high frequency operation and capable of executing a low voltage operation. CONSTITUTION:An input signal REin is amplified by an MESFET 11. An MESFET 12 and a load resistance 13 become the loads of the MESFET 11. The on-resistance of the MESFET 12 is changed by control voltage Vagc and a gain is changed by the MESFET 11. At the time of amplification, a resistor 14 becomes self-bias in the MESFET 11 and 12. A capacitor 15 grounds the sources of the MESFET 11 and 12 in a high frequency manner. A resistor 16 biases the gate of the MESFET 11 to ground potential GROUND. The change of the on-resistance of the MESFET 12 changes the load of the MESFET 11, a potential difference between the drain/source of the MESFET 11 and the gate bias of the MESFET 11, and largely changes the gain of the variable gain circuit.
