Abstract: PURPOSE:To improve various characteristics of a reflector antenna in terms of the molding radiation directivity by combining a rectangular corrugated horn containing a conductor fin formed on its outer wall and the corrugations provided on the two counter inner walls. CONSTITUTION:A rectangular corrugated horn 6 contains the corrugations 9 and 10 provided on two counter faces of an inner tube wall together with a conductor fin 7 formed on the outer wall respectively. That is, the corrugations 9 and 10 are formed on the inner wall of a face where the horn 6 touches a circular corrugated horn 1 and on the inner wall of a face orthogonal to a face containing the fin 7. Then both horns 1 and 6 are combined together into a primary radiator and a reflecting antenna is obtained from a combination of said primary radiator and a reflector 5. The radio waves are radiated to the reflector 5 from the primary radiator. Thus, it is possible to secure the coincidence between the E-face and H-face radiation characteristics in terms of the electromagnetic field distribution of the primary radiator with the conventional arrangement space maintained as it is. As a result, the side lobe characteristics, the cross polarized wave characteristics, etc., are improved in terms of the molding radiation directivity of a reflector antenna.

Abstract: PURPOSE: To make possible the high accurate breadth control, by lowering the rolling speed than the ordinary fixed rolling speed, when the computed roll gap adjustment is impossible because of the adjustable limit.  
     CONSTITUTION: The computed roll gap adjustment is inputted from the roll gap control circuit 6 to the rolling speed arithmetic circuit 8 which then produces the ordinary rolling speed when the value of computed roll gap adjusting speed for the vertical rolling mill is smaller than the speed limit sent from the speed limit setter 9. On the contrary, if the computed roll gap adjusting speed is larger than the speed limit, the rolling speed is determined according to the following formula, on purpose to make the computed roll gap adjusting speed to be smaller than the speed limit, and also, on purpose to minimize the slow-down of the rolling speed. The rolling speed=(limit of roll gap adjusting speed)×(ordinary rolling speed)/(value of computed roll gap adjusting speed). Then, the rolling speed changing unit 10  changes the rolling speed of the vertical rolling mill E 4  according to the output  signal produced from the rolling speed arithmetic circuit 8.

IPC: H04M3/26
Filed: 1991-01-18
Abstract: PURPOSE:To shorten the test time by adding a branch processing text to a subscriber telephone set control procedure program. CONSTITUTION:When a call command is indicated, branch processing is implemented depending whether or not, e.g. a dial tone is heard within 60sec. When no dial tone is heard, the state is initialized and an error number is outputted. When a tone other than the dial tone is heard, the state is initialized and an error number is outputted. Thus, a tested subscriber at an event execution error is automatically initialized and the test time is shortened.

Title: Analog/digital converter
Inventor: HAYASHI KATSUHIKO
IPC: H03M1/44
Filed: 1987-01-27
Abstract: PURPOSE:To attain A/D conversion without deteriorating the phase accuracy of a rectangular FM signal by using the number of detected high level signals appearing at the output terminal of each delaying device so as to sample a bit of fluctuating information in the direction of time width and converting it into the fluctuation information in amplitude direction so as to attain the output of the AD converter. CONSTITUTION:The output of a non-inverting buffer 2 of a 1st stage goes to a high level after a time tau with respect to a point of time when the input signal goes to a high level, and similarly the output of N pieces of the non-inverting buffers 2 goes to a high level after the lapse of time Mtau. The output of the noninverting buffer 2 is inputted to a D flip-flop 3, to which a latch timing signal (c) is applied synchronously with the sampling period. As a result, a latch timing signal is given to the D flip-flop 3 during a period just before the time (N+1)tau from the time Ntau with respect to the point of time when the input signal a goes to a high level, the value N is outputted to the output terminal of an encoder 4. Thus, in repeating the operation, an AD conversion output (d) is obtained at the output of the coder 4.

Abstract: PURPOSE:To receive data on a reception side without regenerating carriers by periodically sending out amplitude and phase reference data of the respective carriers at a determined position in a frame consisting of plural transmitted symbols. CONSTITUTION:The effective transmitted data are interleaved by an interleaving matrix 101 and inputted to a serial/parallel converting circuit 103 while switched with the amplitude and phase reference data stored in a fixed reference data memory 102 under the control of a switching control signal.

Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To arbitrarily set effective TE and an Echo Train Length and to remove ghosts due to the fact that echo strength is attenuated more for echoes at the rear of an echo string. SOLUTION: The entire view of a (k) space is divided into 2 m pieces of segments (W1), a first echo-an (m)-th echo and the (m)-th echo the first echo are successively allocated to the respective segments (W2), and then, the respective segments are cyclically moved so as to bring the segment or a segment interval corresponding to the effective TE to a (k) space center (W3). The allocated echoes are kept as they are for one of the odd-numbered view and even-numbered view of the respective segments, and the ones rearranged in a reverse direction are allocated for the other (W4). Phase encoding is performed correspondingly to an allocated result or the allocated result equivalent to it and data are gathered. Thus, since a long ETL is set even at the time of setting a short effective TE, photographing time is shortened. Images from which the ghosts are removed are obtained.
