Title: Communication method, transmitter and receiver
Inventor: SUZUKI MITSUHIRO
IPC: H04B7/212
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To avoid the continuous matching of a transmission timing with other communication by inserting idle slots among frames at random, changing the cycle of time slots at random and transmitting transmission signals at a timing allocated to a present station. SOLUTION: In the communication from a portable telephone set 5A to a base station 6A, the time slots TS0 at the head of the respective frames are allocated as transmission slots TX0, TX1,... and the transmission signals are transmitted to the base station 6A at the timing of the time slots TS0. In the slot structure of a TDMA system applied to the communication of the portable telephone set 5A and the base station 6A, the idle slots I provided with the same slot length as the respective time slots TS0, TS1,... are inserted among the respective frames at random. Thus, the matching of the transmission timing every time is avoided and the same channel interference is avoided.

Abstract: PURPOSE:To detect the moving vector of the image of a picture surface by providing a two-dimensional window function around the original point of the picture, performing complex Fourier transformation, dividing the coefficient by the absolute value, performing complex Fourier transformation in the direction of time, using the coefficient value as a weight, and applying the least square of a plane passing the original point. CONSTITUTION:Complex Fourier transformation in the direction of X-Y in a region which is cut out with a window function having a radius W with a point (X0, Y0) as the center is performed. With respect to the obtained Fourier coefficient p + qi, (p/r) + (q/r)i is obtained, and the normalization is performed. In the expression, r = (p<2> + q<2>)<1/2>. Then cutting is performed with a window function in the direction of time T, and complex Fourier transformation is performed. With respect to the obtained complex Fourier coefficient in three- dimensional distribution, the coefficient corresponding to a frequency is made to be m(fx, fy, ft) + in(fx, fy, ft), and k(fx, fy, ft) = (m<2> + n<2>)<1/2> is obtained. A plane equation fxU + fyV - ft = 0 corresponding to moving vector (U,V) is applied with (k) as a weight. In this method, the moving vector can be detected only by the operation which does not include convergence computation.

Title: Flip-flop circuit
Inventor: NISHITOBA SHIGEO
IPC: H03K3/288
Filed: 1984-03-26
Abstract: PURPOSE:To prevent a malfunction when a power supply has a short break by connecting a capacitor in parallel to a base resistance of one of both transistors of an FF circuit and supplying the complementary output of the FF circuit to a differential amplifier connected with a discharging transistor and a capacitor through an input terminal at one side. CONSTITUTION:When a set signal is supplied to an input terminal 3, an output terminal 5 is set at an H level by an FF action. At the same time, a capacitor 14 is charged by the base current of a TR7. While a capacitor 24 is discharged when TR17, 19 and 23 of a differential amplifier are turned on. Here the power supply voltage is reduced by noises and each TR is cut off and then reset. In such a case, the TR7 is first turned on by the speed-up capacitor 14 to set the output of the TR14 under a state set before a short break of the power supply. While an output 5 is set an L state in a reset mode and the power supply has a short break. Thus the base current of a TR8 flows via a resistance 10 by the charged electric charge of the capacitor 24 to reset a state set before the short break.

Title: Developing device
Inventor: KINASHI HIROSHI
IPC: G03G15/09
Filed: 1983-03-30
Abstract: PURPOSE:To prevent sticking of a carrier, especially, at a start time to form always vivid pictures by impressing a developing bias voltage after starting a magnet roller. CONSTITUTION:The movement of a developer 62 existing between a photosensitive body 1 and a magnet roller 63 becomes irregular at a moment when the roller 63 is started, and its magnetic attraction becomes weaker than that in the steady state. Therefore, if a developing bias voltage 66 is applied before the roller 63 is started, the electrostatic attraction to the photosensitive body 1 becomes stronger, and sticking of the carrier occurs. The bias voltage 66 is not impressed until the magnetic attraction of the carrier to the roller 63 is normal, thereby preventing sticking of the carrier. For example, if the developing bias voltage 66 is raised 100msec after the start of the roller 63 by a switch means 9 when potentials of the photosensitive body in image bright and dark parts are set to -150V and 450V respectively and a non-image part is set to -350V by image exposure 4, sticking of the carrier does not occur even when the bias voltage is 350V.

Filed: 1988-03-12
Abstract: PURPOSE:To estimate the 3-dimensional attitude of an object at high speed by securing the correspondence between the features of an input picture and the descriptions of features in the description of an object model for selection of four points and estimating the attitude of a virtual tetrahedron formed by the 3-dimensional coordinate values in the description of the object model corresponding to said four points for estimation of the attitude of an object corresponding to the input picture. CONSTITUTION:The correspondence is secured between the feature points of a camera input picture and the features of the object model description of a prepared subject. Then four points are selected based on the matching properties between those features. For a virtual tetrahedron formed by said four points, the attitude candidates of 3-dimensional spaces are obtained independently of each other for four trihedral apexes included in the tetrahedron. Then the attitude candidates which are not compatible with each other are successively deleted out of those candidates of the 3-dimensional spaces. Thus the attitude of the virtual tetrahedron is finally estimated. As a result, the attitude of a camera subject can be estimated in a 3-dimensional space.
