Title: Inverter equipment
Inventor: OOKASHIWA YOSHIHIRO
IPC: H02P27/06
Filed: 1986-09-10
Abstract: PURPOSE:To switch from an inverter to a commercial power supply without shocking a load and a power supply, by synchronizing the input and output of the inverter when making said switching. CONSTITUTION:Input and output voltages of six-pulse inverters 10 and 11 are compared with each other by a synchronous detection circuit 13 to confirm whether synchronous conditions of each of voltage, frequency and phase of respective six-pulse inverters are satisfied or not within a certain tolerance. If synchronous conditions are not satisfied, inverter phase correction signals 16 and 17 are outputted for each six-pulse inverter. If the synchronous detection circuit 13 detects that the synchronous conditions of all six-pulse inverters are satisfied, a closing signal 15 for switches 2 and 5 are outputted from the synchronous detection circuits 13 while the inverters 10, 11 are stopped.

Filed: 1984-10-09
Abstract: PURPOSE:To improve the frequency characteristic of a detected output voltage by providing a DC cut-off capacitor to the isolation port of a directional coupler for detecting a microwave power so as to eliminate the effect of parasitic capacitance. CONSTITUTION:The coupled quantity is extracted properly by using a micro wave split line reaching an RFC27 to extract a signal from a main line. In such a case, a DC current flows as shown in the arrow, but since the DC cut-off capacitor 25 is provided, the DC current flows to the REC27 and a potential difference is generated at the resistor of a detection output load 29. The poten tial difference is read by a DC voltage pickup lead 31 to eliminate a detection diode 28 from being affected due to the parasitic capacitance.

Title: Water purification system, agricultural product culturing system, water purifier and air water making device
Inventor: KANEKO NORIO
IPC: C02F1/20
Filed: 1992-07-17
Abstract: PURPOSE:To ensure that water is purified using a natural purification phenomenon even in an area where a system power supply cannot be obtained by mixing water to be purified with air and releasing the mixture from an air scattering plate in a water purification system which releases air using a solar cell. CONSTITUTION:If a solar cell 5 starts electric generation, an air is automatically fed by a compressor 6 to be released from an air scattering plate 3. In this case, the air is discharged into the water so that mud at the bottom is not swirled up. In this water purification system, it is important to make oxygen bubbles in the air as fine as possible. This purpose is to increase the migration efficiency of oxygen by making the bubbles fine and feed oxygen slowly and steadily into an area to purified. In order to achieve this purpose, it is necessary to mix water with air prior to the release of the air from the air scattering plate 3, and produce fine bubbles to a maximum permissible extent during the mixing operation. The mixture is released into the water from the scattering plate 3.

Title: Sheet conveying device and image forming device
Inventor: IZUMI MAKOTO
IPC: G03G15/00
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To set tolerance to a curl quantity of a sheet by disposing a sheet face height detecting means away from a feeding member in a vertical direction to a sheet conveying direction within the plane of sheets stacked on a stacking member. SOLUTION: When a sheet conveying device starts its action, the uppermost face of sheets 5 is moved up by a sheet elevating tray 30, and a sheet contact member 20 comes in contact and moves together. A sheet face sensor 21 detects the movement of the sheet contact member 20 and recognizes the height of the sheet 5 at a part in contact with the sheet contact member 20. When a height of the sheet 5 reaches a feeding standard position H1, driving transmission to the sheet elevating tray 30 is stopped, and a pickup roller 10 is lowered onto the sheet 5 and also rotated to deliver the sheet 5. A tolerance of a curl quantity per a length of detection space L1 so as to be stably conveyable by the sheet conveying device is set to a distance from the standard position H1 to a lower limit position H2. The sheet is not therefore conveyed in the case of the curl quantity exceeding the tolerance.
