Title: Photovoltaic power generation system
Inventor: YAMAGUCHI MASAHIDE
IPC: G05F1/67
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To reduce loss during independent operation and obviate a transformer for load by interlocking a boosting chopper during linked operation and stopping it during independent operation, and supplying a load with 100V alternating- current. SOLUTION: A load 9 is isolated from a system 7 by means of a switch 10 during linked operation. If any trouble occurs in the system 7, a switch 6 is opened to disconnect a power converter 2 from the system 7, and the power converter 2 switches to independent operation. An inverter exercises control so that output voltage will be 100V alternating-current. When the operation of a boosting chopper 2 is stopped and the switch 10 is closed to stop the boosting chopper 2 that supplies a load 9 with power, a direct-current voltage generated using a solar cell 1 is applied direct to a smoothing capacitor 4. As a result, the input voltage, that is, the voltage of the smoothing capacitor 4, required for the inverter 5, is only half of that during linked operation. This reduces the loss in the voltage converter and obviates a transformer for load.

Title: Combustion method for sewage sludge
Inventor: YAMAZAKI MASAKAZU
IPC: F23G7/00
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To accomplish high temperature molten ash combustion higher than the melting point of ash while recovering excess thermal energy by drying up sludge appropriately using oxygen gas in combustion. SOLUTION: When oxygen is used in combustion, volume of combustion gas is reduced by a factor of about 4 as compared with air combustion because nitrogen gas is not present and combustion temperature increases in reverse proportion to reduction in the thermal capacity of combustion gas. In case of oxygen combustion, combustion temperature of 1570 deg.C is realized even when water content is 65% (moisture contained in sludge is 1.87 kg/kg-DS). Since nitrogen gas is not present in the combustion gas, volume of combustion gas is small and high combustion temperature can be attained even if the water content is high. When oxygen combustion is applied, high temperature combustion for sustaining molten ash combustion can be ensured without requiring any preheat of oxygen even if dry up of sludge is lessened significantly.  Consequently, conventional auxiliary boiler and air preheater are eliminated and since the volume of dry up steam being produced from a waste heat boiler can be reduced significantly, excess thermal energy can be recovered.

Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To improve a phase characteristic like software by using prediction control logic in a PLL circuit which looks ahead a noise signal and a target (input) signal to some extent. SOLUTION: A discrete state equation and an output equation are determined from the transfer function of a PLL circuit (100), and an error of a target signal and an output signal is defined (101). An equation of state variables and errors is acquired from each above expression and an error system is acquired (102). An evaluation function that reflects the prediction control of the target signal and noise signal is taken in and control input is calculated (103 and 104). The current value of the control input is calculated and added to a just preceding target value and made the current PLL input (105 and 106). The next control input is calculated again (107), and it is added to a just preceding target value and made a PLL input. By repeating the above, a phase characteristic can be improved.

IPC: B23K11/11
Filed: 1990-11-22
Abstract: PURPOSE:To maintain spot efficiency by providing a welding robot group to move in the front and rear directions of a car body above the car body, two welding robot groups to move in the front and rear directions of the car body respectively on the right and left sides of the car body and a welding robot group to move in the front and rear directions of the car body below the car body. CONSTITUTION:The welding robot group A above the car body 1 performs spot welding from above the car body while moving in the front and rear directions of the car body and the welding robot groups B and C on the right and left sides of the car body perform spot welding from the right and left sides of the car body while moving in the front and rear directions of the car body. The welding robot group D below the car body performs spot welding from below the car body while moving in the front and rear directions of the car body. Since the welding robots can take partial charge of welding work so that the mobile ranges are not superposed mutually among the robot groups, even if many welding robots are arranged with high density, the spot efficiency can be easily maintained while avoiding the mutual interferences among the welding robot groups. Consequently, the increased spot stage of spot welding after the tack assembling stage is obtained at one place, the space efficiency is increased and accuracy of the welding position can be maintained.
