Title: Cross polarized wave interference rejecting circuit
Inventor: TAWARA MASATO
IPC: H04J11/00
Filed: 1984-11-21
Abstract: PURPOSE:To always control stably a variable coupler even if a phase difference be tween recovered carrier signals of an interfered side and an interfering side by provid ing a means for applying inverse modulation to a signal obtained at a demodulator at the interfered side, using a recovered carrier signal for an interference side demodulator and obtaining an error signal at an error signal demodulator. CONSTITUTION:An intermediate frequency signal independently of a phase of a signal Ch is produced in an output of a modulator 9 by using a recovered carrier signal Ch of an H polarized wave demodulator 6 at the interfered side to a local signal of the modulator 9 and its error signal is obtained in an output of a subtractor 10. The error signal is a V polarized wave included in a V polarized wave reception signal IFv itself. The said error signal is demodulated by an error signal demodulator 11 using a recovered carrier nsignal Cv of a V polarized wave demodulator 3 at the interfering side as the local signal. Since a data signal D at the interfering side to the correlated to the said error signal E is demodulated by the signal Cv, a correlation output signal independently of the phase amount of the signal Cv is obtained at the output of a control signal generator 12. This is inputted to the variable coupler 4 as a control signal.

Title: Manufacture of surface wave filter
Inventor: INOHARA JUNICHI
IPC: H03H3/08
Filed: 1986-10-17
Abstract: PURPOSE:To improve the accuracy and to prevent a fault such as short-circuiting by providing a com bline electrode onto the major plane of a piezoelectric substance such as single crystal, and forming a layer of the piezoelectric substance such as zinc oxide on the comb line electrode, thereby suppressing the variance in the center frequency. CONSTITUTION:Comb line electrodes 3, 3' are provided on the major plane of the piezoelectric substrate 1 such as single crystal and zinc oxide is sputtered to the electrodes 3, 3' to form a zinc oxide thin film 5. In supplying an electric signal to an input lead electrode 9', the signal reaches the electrode 3' via a wire 8 and a pad electrode 4 and converted into mechanical vibration through the piezoelectric effect. Then the vibration causes a surface wave, which is propagated toward the electrode 3 and converted into an electric signal and an output signal is obtained from the output side lead electrode 9 via the electrode 4 and the wire 8. In such a case, in providing an optional characteristic to the input/output electrodes 3, 3', the output signal has a frequency characteristic subject to filtering as the set characteristic. Thus, the dispersion in the center frequency is suppressed to improve the accuracy and a fault such as shortcircuiting due to the adhesion of a metal between the electrodes is prevented.

Abstract: PURPOSE:To detect a foreign metallic matter with a small diameter existing inside, by closing a breaker within 100msec to apply an AC voltage to a gas insulated switch after a voltage is applied to a fixed level on one side thereof with the breaker opened. CONSTITUTION:A gas insulated switch (GSI) 1 normally has breaking devices 3 and 4 arranged on both sides of a breaker 2. The breaker 2 is opened while the breaking devices 3 and 4 are closed.

Filed: 1990-09-18
Abstract: PURPOSE:To reduce defective detection of erroneousness of a lead position in a bonding operation by a method wherein a lower-part glass layer at the side of a lead tip part inside a semiconductor device is removed. CONSTITUTION:Leads 4 are fixed to a ceramic base 3 by a glass layer 5 by means of a thermocompression bonding operation. Metal thin wires 6 which are used to electrically connect the leads 4 to electrode pads on a semiconductor element 1 are bonded as required. A ceramic cap 2 is bonded to the ceramic base 3 via the glass layer 5 so as to cover the semiconductor element 1 connected by the leads 4 and the metal thin wires 6.

Title: Control device of travelling drive source motor for electric motor car
Inventor: SAITO YOICHI
IPC: B60L15/20
Filed: 1985-11-06
Abstract: PURPOSE:To make it possible for an electric motor car to get over the gig road level or to climb up a short steep slope by increasing a maximum value of current for a specified time when the command value comes to maximum. CONSTITUTION:When a driving current from a battery 12 to a motor 10 reaches a current Imax set up by a maximum current setting circuit 32, the driving current of the motor 10 is limited to a current value Imax for some time due to the action of a current limiting circuit 30. When the delay time T1 of an on-delay timer 50 elapses from that moment (interpreting that a larger output is demanded as the accelerating pedal is being continuously pressed), the set voltage of a divider 54 is added to the maximum current setting circuit 32 for a specified period. As a result, the driving current of the motor 10 is increased to the current Ipeak, more powerful than the maximum current Imax to which is has been limited so far.

IPC: A01G9/02
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To raise the operating efficiency in spacing operations and reduce the cost by collectively taking out pots housed in intermittent positions from trays housing many potted plants. SOLUTION: The trays for plant seedlings are obtained by providing openings of the same diameter at a prescribed interval in the longitudinal or transverse direction or longitudinal and transverse directions, preparing the plural trays having bottomed pot receivers in the openings located at intermittent places in the respective openings, making the respective bottomed pot receivers in either of the trays enter the openings without any bottomed pot receivers in the other tray and mutually superposing the trays.
