Filed: 1978-08-31
Abstract: PURPOSE: To make small the extension of the bubble and the control current value during cutting to facilitate the single mask of the patterning by dispose the disc type magnetic generator at the same row as the transfer passage of the magnetic bubble.  
     CONSTITUTION: If the rotating magnetic field is directed to right ward, the species bubble B is retained at a right end portion of the generator G. When the rotating magnetic field progresses and is directed downward, the bubble B is absorbed by a right below cornered portion 5 and at this time, also at left below position 41e of the adjacent transfer pattern 41, absorbing magnetic pole is generated. By flowing the control pulse through the control lines 6, 6', the bubble is enlarged bridged. When the rotating magnetic field is further progressed and directed leftward, the bubble B is extended to the left end, so that when the rotating magnetic field is from the leftward to a little more rotating position, if the reversing control current to the time when the bubble is expanded is impressed between the control lines 6, 6', the bubble is easily cut off and the divided bubble b is fed to the transfer passage.

Filed: 1984-05-28
Abstract: PURPOSE:To reliably form a fold in the center of the paper one by one providing a gapped-periphery roller and a stopper arranged to suit the size of the paper on a paper folding unit. CONSTITUTION:The tip of the paper P passes conveyor rollers 47, 48 and sponge rollers 51, 51 and hits a stopper 54 arranged in advance to suit the siae of the paper P and is stopped. Since the paper P is further conveyed, it starts to be bent near the end of a passage 50. At this time, a gapped-periphery roller 49 is rotated once by being timed by the signal of a sensor 53, the bent paper P is bitten between the conveyor roller 47 and the roller 49 to form a fold in the center of the paper P. Then, the gapped-periphery section of the gapped-periphery roller 49 faces the conveyor roller 47, but the said stopper 54 is allowed to escape from a passage 52 beforehand, thus the conveying force by the gapped- periphery roller 49 is eliminated, and the paper P formed with a fold in the center is conveyed by the conveying force of the sponge rollers 51, 51 and is fed to a paper binding unit from the direction of conveyor roller 55, 55.

Title: Stream data transfer device
Inventor: NISHIKAWA JUNJI
IPC: G06F13/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To control data transfer at a storage device side regardless of the state of an input/output port and to easily test the state of a DMA operation by detecting a frame signal which is inputted from the input/output port and inputting data indicating a frame in place of data. SOLUTION: When the order of data in the frame is outputted, the value of a frame data counter 35 is outputted in placed of stream data which is inputted from the port. The frame data counter 35 successively executes counting in accordance with data transfer after resetting by a frame pulse. Therefore, when the input of stream data is checked, an operation for fetching data by DMA can be checked regardless of the data state at a port side. In this case, data stored in a memory can be easily checked since a number is given to order. A pseudo frame input operation is also enabled even at the time of the state without no port signals at all.
Patent JP-H044690-A (JP)
Title: Signal generating circuit
Inventor: TAGIRI HIROKAZU
IPC: H04N5/91
Filed: 1990-04-23
Abstract: PURPOSE:To prevent a duty of a pulse for a reference period from being changed even when a reference period is changed by providing a means deciding the reference period, a counter having a period being 1/2 of the reference period, and a pulse generating means generating pulses whose output levels change reverse at each prescribed point of two consecutive periods of the counter. CONSTITUTION:An internal reset pulse is produced at a period being a half the reference period to a reset line 5 even in the normal mode or the reverse(REV) three-time speed reproduction mode. This is easily realized by setting a data given from a ROM 2 to switch circuits S1-S5 in terms of the software. When the period (then reference period) of a counter section 1a is short, the trailing of the level at a terminal Q is fast and when the period of the counter section 1a is longer, the trailing of the level at the terminal Q slows down. Thus, the duty (at reference period) of the pulse outputted from the pulse generating circuit 3 is always 50%.

IPC: G01S13/90
Filed: 1986-05-09
Abstract: PURPOSE:To enhance the searching capacity of a ground embedded article, by providing a means for performing gain correction in front of an azimuth compression means. CONSTITUTION:The transmission signal (a) from a transmission antenna 2 is reflected from a target to be converted to a video signal of a base band through a receiving antenna 3 and a receiver 4. Sugsequently, the video signal is separated to a range direction with distance resolving power corresponding to a transmission pulse width by a range gate means 5. Necessary receiving signal data are arranged on a memory means 6 and, in order to enhance the resolving power in an azimuth direction, that is, in the advance direction of a rader apparatus, synthetic aperture processing is performed by an azimuth compression means 23. Because an underground article is an observation object in the apparatus of this kind, signal attenuation or range movement due to range migration are large as compared with the observation of the ground or the sea level. Then, a gain correction means 7 is provided in front of the means 23 to correct the attenuation of a high frequency component due to range migration. By this method, azimuth resolving power is enhanced and the searching capacity of a ground embedded article can be enhanced.
