Title: Current limiting circuit
Inventor: INOUE ISAMU
IPC: H02H9/02
Filed: 1987-12-08
Abstract: PURPOSE:To enable current limiting operation to be performed by connecting a stationary type blind controller through a CT in series between two breakers connected in series in an uninterrupted power supply unit and a load side and detecting a flow of current for whether it exists or not. CONSTITUTION:An uninterruptive power supply unit 1 of uninterruptive power supply equipment A supplies a power source of constant voltage and constant frequency.

A stationary type blind controller 22a, connected to the CT21a, detects a load current. A control unit 23 makes the electromagnetic contactor 3 open, when no load current flows, and supplies the current through the rush current preventing resistor 20a when power is fed to the load, closing the contactor 3 after a predetermined time. About the side of a breaker 12, the control unit 23 similarly performs the action. Thus only by detecting the load current for its presence in each load circuit, limitation of the current is surely performed, and power interruption is prevented.

Title: Manufacture of ceramics sheet
Inventor: TANAKA HIROTOSHI
IPC: H01G4/12
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a ceramics sheet, wherein with sheet surface being smooth, a peeling of carrier film, etc., off a support is easily performed. SOLUTION: At a first painting device 1a, a slurry coated on a carrier film F is dried at high temperature in a short time. Here, although the surface of slurry is roughened by a trace of boiling solvent, etc., resulting in a rougher surface, peeling from the carrier film F is easy since no binder precipitation is accompanied. Further, a slurry is coated on the dried slurry by a second painting device 1B, and dried at a temperature lower than the former to provide a ceramics sheet. As a result of this, no boiling of solvent takes place with the slurry, resulting in a smooth upper surface of the slurry, and the slurry is filled into a pin hole of the slurry, which is already dried and a recessed part of surface rough while a binder precipitates on a bottom part of the binder, increasing the adhesion between the slurry and the slurry dried earlier.

Title: Pneumatic circulating and filtering device for aquarium for appreciation
Inventor: HAMAGUCHI SHIGEO
IPC: B01D35/027
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic circulating and filtering device, installed in an aquarium for appreciation, capable of circulating a liquid only by an air pressure, capable of filtering turbidity in the liquid, and excrement of fish or the like, capable of supplying oxygen to the water and capable of allowing the state to be observed by the naked eye, and further to provide a filtering plate on a bottom plate, having an attached copper thin plate. SOLUTION: This pneumatic circulating and filtering device is made of a transparent synthetic resin, and installed in a liquid of the aquarium for the appreciation. The filter is regulated so as to be present on the liquid surface. The liquid naturally enters the air-tight vessel having an inflow valve, and when the compressed air is sent from an air opening to a pipe, the liquid in the air-tight vessel is pushed out through a circulating pipe to the filter. At the time, a safety valve under the water surface is operated by the increase of the inner pressure to open the safety valve and to supply oxygen. As a result, the inner pressure is rapidly reduced, and the inflow valve is opened to introduce the liquid into the air-tight vessel again. The processes are repeated alternately, and the operations are carried out only by the compressed air.  A copper thin plate is stuck on the surface of the filtering plate of the bottom plate, having different characteristics. The copper thin plate is effective against infectious disease of fish because of a bacteriocidal action of a copper ion. The copper thin plate can maintain comfortable environment for the fish because it is recognized that the plate decreases slime in the liquid.

Title: Pwm controlled self-excited rectifier
Inventor: SASAKI TOSHIYUKI
IPC: H02M7/219
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To suppress the rise of the DC voltage of the output of a PWM control self-excited rectifier by a method wherein a current instruction value is quickly switched to the value of a regenerative current direction when the DC voltage exceeds a limit value. SOLUTION: If a regenerative current flows into a PWM controlled self-excited rectifier, the output of the regulation calculation unit 21a of a voltage regulator is reduced and approaches a regenerating region. If a DC voltage between both the ends of a capacitor 13 exceeds a limit value, a value which is obtained by adding the output value of the regulation calculation unit 21a to a negative maximum current limit value is used as the input value of the limit calculation unit 21b of the voltage regulator. Then a current instruction value is put into a regenerative state and the DC voltage between both the ends of the capacitor 13 starts decreasing. If the DC voltage between both the ends of the capacitor 13 is reduced to be below a limit value, the current instruction value is switched to the output value of the regulation calculation unit 21a.  By repeating the above mentioned procedure, the DC voltage between both the ends of the capacitor 13 is suppressed to the value below the limit value even if the regenerative current keeps on flowing into the PWM control self-excited rectifier.

IPC: G05F3/24
Filed: 1986-12-25
Abstract: PURPOSE:To quickly reach a stable operation state by connecting a starting MOS transistor TR between the gate of a MOS TR for constant current circuit operated in a weak inversion area and a prescribed power supply node. CONSTITUTION:In case of switching from the stand-by state to the operation state, a reset signal is inputted after switching from '1' to '0'. When kick pulse signal input K1 goes to active level '1', an N-channel TR TN4 is turned on connected as a starting circuit and the level of a node N1 falls and P-channel TRs TP1 and TP2 are turned on. Then, the level of the drain (a node N3) of the P-channel TR TP1 goes to '1' and N-channel TRs TN1 and TN2 are turned on. Though the kick signal input goes to non-active level '0' in this state, the circuit surely and quickly reaches the stable state of circuit operation from turning-on states of TRs TP1, TP2, TN1, and TN2.
