Title: Image display device
Inventor: HIROKI MASAAKI
IPC: G02F1/13
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To relax noise intensity in a drive circuit to an extent not affecting a display by providing a delay means in a prescribed part and deviating a phase relation between two signals existing in an inverted relation by a prescribed amount. SOLUTION: A minute phase difference (time difference) is provided between first clock signal (CL) 117 and second clock signal (CL) 118 formed by a signal generator 107 to be inputted to the drive circuit. At this time, a delay circuit 100 is integrated into a control circuit 108 for providing the minute phase difference (time difference). Although the phase difference (time difference) provided between the first clock signal (CLD) 123 and the second clock signal (CLD) 124 is able to take a wide range within the range of normally driving the circuit, the range is made at least a rise period or above, or a fall period or above, and is made a half or below of a hold period (period from one output pulse to next output pulse). That is, the range of the phase difference is 1-90 degrees.

Abstract: PURPOSE:To lower suspended solids in purified water to the minimum, by changing a set value of dissolved oxygen concentration in response to a volume index of sludge, and controlling an amount of air to be supplied into an aeration vessel while using the changed new dissolved oxygen concentration as an objective value. CONSTITUTION:SVI meter 21 is arranged in an aeration vessel 1 to feed measured data to an arithmetric unit 22. An objective value of dissolved oxygen concentration preset by a setting instrument 7 is applied to the arithmetic unit 22.

Filed: 1982-07-27
Abstract: PURPOSE:To adjust the characteristic impedance of a strip line easily by mounting a dielectric piece in an adequate shape on both a center line conductor and a dielectric substrate, and then adhering and fixing it. CONSTITUTION:One surface of a triangular dielectric piece 40 is coated previously with an adhesive, and the piece is arranged at an adequate position of a strip line 20. In this case, the dielectric piece 40 is mounted on both a center line conductor 21 and a dielectric substrate 22. For accurate positioning, the dielectric piece 40 is slid as shown by an arrow A firstly and the position of the reference point of a reflected wave having the opposite phase to the reflected wave of a coupling part is searched for. After the position of the reference point of the reflection is determined, the piece is slid as shown by an arrow B and the amount of a reflected wave at this part is approximated to the best conditions. Thus, the phase and amount of the reflected wave capable of cnaceling the reflective wave at the coupling part are adjusted, and consequently the characteristic impedance of the strip line 20 is adjusted.
