Title: Target detector
Inventor: YAJIMA NOBUHIRO
IPC: G01S13/06
Filed: 1989-03-22
Abstract: PURPOSE:To obtain a three-dimensional target position data with a high accuracy quickly by storing information on the presence of a target at a position of a memory corresponding to a directing position to read out contents of the memory with a processor when specifying a target position by a marker setting. CONSTITUTION:A memory control section 16 stores information on the presence of a target in a direction at a distance from a target signal compression circuit 9 at a position of a memory 10 corresponding to azimuth and depression of a target based on a directing position of a radio wave transmitted and received. Display device 5 displays a distance and azimuth in the memory 10. Under such an arrangement, when an operator sets a marker at a position of a target on the display device 5, a processor 17 reads out all depressions containing the perimeter of the distance and the azimuth set by the marker in the contents of the memory 10 thereby enabling the obtaining of a three-dimensional target position data with a high accuracy.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a display device with less power consumption and a high quality display even when gate line capacitance is increased. SOLUTION: Charges stored in the gate line (scanning line) capacity (C1, C2,..., Cn) are stored temporarily in a charge preserving capacitor CD arranged so that the charges are shared with respective gate lines (D1, D2,..., Dn), and thereafter, gate line drive is performed successively while using the charges for charging the gate line capacity. That is, a HIGH level signal is applied to the certain gate line Di to charge the gate line capacity Ci, and after a fixed period, after the charges stored in the gate line Di are transferred through a charge transferring inductor L to be preserved temporarily in the charge preserving capacitor CD, by transferring them to the next gate line capacitance, the HIGH level signal is applied to the gate line.  After the charges are transferred, only the charge by the lost charge much is supplied from the outside, and the HIGH level signal of a prescribed potential is applied to respective gate lines.

Filed: 1988-03-24
Abstract: PURPOSE:To inspect diverse patterns by one device by providing a short-circuit bar for short-circuiting one opening end sides of a conductive pattern to be measured mutually and a measurement terminal unit consisting of three terminals at the other opening end sides. CONSTITUTION:When short-circuit inspection is performed, an actuator 8 removes the short bar 9 from the conductive pattern 2 to be measured to open all terminals. Then the measurement terminal (A-C) unit 6 fitted to a movable fitting bar 5 is brought into contact with the pattern 2 and swept by a driving motor 3. The continuity between terminals A and B adjoining to each other in the sweeping direction is inspected and when, for example, terminals A and B reach patterns P5 and P6, a short-circuit part P5' is detected and its position coordinates are stored in a CPU 7. Then when disconnection inspection is performed, the bar 9 is swept in contact with all the opening ends of the unit 6 on the opposite side. The moment at which terminals A and C which adjoin to each other at right angles to the sweeping direction are on a pattern P4 is recognized with the closure signal between the terminals A and C and the current continuity between the terminals A and B is inspected to judge nonconduction from a disconnection part P4'.

Title: Feeder for sheetlike material to be fed
IPC: H01L41/09
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a feeder for a sheetlike material to be fed which has a small size and a simple structure. CONSTITUTION:A second piezoelectric actuator 5 is deflected by applying a voltage thereto from control means 12 to press a material-to-be-fed presser 6 to a clamper 4. A first piezoelectric actuator 1 in which the clamper 4 is mounted is deformed by applying a voltage thereto from control means 12 to displace both wing pieces 2a, 2b of enlarging means 2 in a sheet feeding direction Y1. A sheet pressed by the clamper 4 by the presser 6 is fed in the feeding direction by this displacement. Thus, a feeder for a sheetlike material to be fed which has a smaller size than that having a stepping motor and a gear train and a simple structure is obtained.

Abstract: PROBLEM TO BE SOLVED: To execute adequate recording with a magnetic force sufficient for magnetic disk by constituting magnetic path member in an inverted U shape, installing coils respectively to both of the pole side and return magnetic pole side of the magnetic path member and connecting these coils in such a manner that signals are added to each other. SOLUTION: The application and reception of magnetic fluxes to and from the magnetic disk F are executed in the state that the pole B comes into contact or pseudo contact with the front surface Fa of the magnetic disk F and, therefore, the efficient transmission of the magnetic fluxes between the pole B and the magnetic disk F is executed when the magnetic recording and reproducing to the magnetic disk F are executed. Then, even if the magnetic fluxes applied from the coils E, E1 to the pole B at the time of recording are relatively weak, the adequate recording is executable on the magnetic disk F with a sufficiently magnetic force.  The pole B is able to obtain strong magnetic fluxes from the magnetic disk F and a large electric signal is obtainable in the coils E1, E2 at the time of reproducing and since the addition of the respective signals on the coils E1, E2 is possible, the sensitivity of recording and reproducing with the electric signals obtd. by both coils E1, E2 is additionally improved at the time of reproducing.
