Title: Digital radio receiver
Inventor: ONO YOSHIAKI
IPC: H04B7/08
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a signal with the optimum reception sensitivity by deciding either interference phasing or attenuation phasing according to reception levels in the prescribed frequency bands of received signals on a main side and a space diversity(SD) side and selecting the reception signal with the less bit error rate(BER). CONSTITUTION:In the case of generating the interference phasing or the attenuation phasing in a reception coefficient on the main side or the SD side, signals are outputted from reception parts 1 and 4 and equalizers 2 and 5. In such a case, the reception levels are detected by sweep detection parts 3 and 6 while being swept at every several MHzs, for example. Then, a control part 7 decides whether the degradation of the reception level is the interference phasing or the attenuation phasing, and based on the decided result, the BER corresponding to the interference phasing or the BER corresponding to the attenuation phasing is calculated. Next, the BER of two reception systems are compared and a selective signal is generated to select the reception signal with the less BER. According to this selective signal, a selective part 8 selects the reception signal from the sweep detection part 3 or 6 and sends it to an ACC amplifier 9.

Inventor: TAKENAKA TOMOHIKO
IPC: G01R31/26
Filed: 1988-02-09
Abstract: PURPOSE:To shorten a measurement working time by selecting a frequency of relaxation oscillation above the predetermined set value. CONSTITUTION:Semiconductor laser lights having relaxation oscillation frequencies above a desired set value, i.e., a critical relaxation oscillation frequency or more are selected from a semiconductor laser which oscillate in the single longitudinal mode, and the selected semiconductor laser are incorporated in a light emission source. Thus, the propriety of the laser used by a high speed modulation is sorted according to whether or not the relaxation oscillation frequency by the measurement with the laser is the critical relaxation oscillation frequency or more. Accordingly, a bit error rate is not necessary measured in an actual light transmission system, and the measurement work is simplified. Thus, the measurement working time can be shortened.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce the work function of a crystal, and control the characteristic of an efficient electron beam emitting source and catalytic reaction efficiency in an electron emission material by artificially forming two-dimensional or three-dimensional structure on the crystal surface. SOLUTION: A crystal surface serving as a substrate is slanted and cut, the surface is cleaned to form step structure 1 on the surface. A step distance 2 is varied by a cutting inclined angle. An alkali earth metal such as Ba, or an alkali metal 3 such as Cs is adsorbed in the structure 1. By annealing or cooling, Ba is oxidized to a BaO single atomic layer, and it is selectively adsorbed in a step site 4. The BaO single atom becomes two-dimensional long periodic structure in the same period as the distance 2 of the step structure. The BaO becomes a positive electric dipole to reduce work function, but by forming the long periodic structure in the step site 4, the dipole moment of the electric dipole is increased, and decreasing value of the work function according to an increase in the dipole moment is increased.

Title: Output interrupting circuit of logic circuit
Inventor: IGI YOUZOU
IPC: H03K19/00
Filed: 1984-02-17
Abstract: PURPOSE:To interrupt an output until a signal output source of various peripheral devices is operated normally by using a one-shot multivibrator triggered based on a reset signal and a clock signal of a microcomputer. CONSTITUTION:The clock signal and the reset signal are ANDed by an AND gate G1 and the resulting signal triggers the one-shot multivibrator MV. The operating time of the vibrator MV is set longer than the longest time of an expected unstable time of various peripheral devices. Since an output signal of the MV is inputted to an ANG gate G2, so long as the MV is operated, the signal output of a signal output source SIG is interrupted. Thus, the output is interrupted until the signal output source of the various peripheral devices is operated normally.

IPC: G01N29/04
Filed: 1979-03-14
Abstract: PURPOSE: To accurately and stably measure an initial impact wave component only, by converting impact elastic waves into an electric signal by piezoelectric element, and extracting this signal as a pulse of a predetermined level.  
     CONSTITUTION: A detector element 20 of an impact wave detector 10 is pasted on such a portion of the surface of an objective material 1 that is in the vicinity of another portion thereof to which an impact is to be applied. Impact elastic waves occurring when the material 1 is struck bring initial oscillations in an extremely short period of time to the detector element 20 of the impact wave detector 10. These oscillations cause a piezoelectric element 24 to generate between positive and negative plates 22, 23 an electric signal in accordance with the level of strain occurring in a strain element 24. This signal is input into an input terminal 31 of a signal generating circuit 30 through a connector 25, rectified by a diode 33, converted into a pulse wave form of a predetermined level by a Schmitt trigger circuit 34, and sent to an output terminal 36 through a coupling capacitor 35. Since the element 24 is operated at a frequency of not less than 500Hz, it is not adversely affected by oscillations caused by vehicles. Owing to the use of an electric pulse, an initial impact wave component only, which satisfies predetermined conditions, can be securely extracted.

Title: Controller for vacuum cleaner
Inventor: MOCHIDA NORIHITO
IPC: A47L9/28
Filed: 1992-02-18
Abstract: PURPOSE:To suppress an input to an electric blower when a floor nozzle is operated upward in the air by determining a correction value due to pressure information by a linear approximation to control a pressure in the inside of a dust collection chamber or the like with the correction of variations in the apparatus. CONSTITUTION:When a floor nozzle is put in the air, a suction pressure is at its maximum. At this point, an input power is also at its maximum. When the floor nozzle is put on a carpet or the like, the suction pressure is almost at its minimum. Phase firing angle time determining an input power of a cleaner other than that is decided by linear approximation. A signal level from an A/D conversion section 26 is always kept constant with a control section 29. For example, when the floor nozzle is put on the carpet from the air to start a cleaning, the amount of the air sucked reduces and a pressure lowers with a less sucking load of an electric blower. Pressure change is checked with a pressure detector 22 and an output signal level of the A/D conversion 26 rises. To raise the pressure of the electric blower 20, the control section 29 works to advance a phase firing angle so that a pressure value of the electric blower 20 is put back to the original level thereby achieving a constant pressure control.
