Title: Drive circuit for bidirectional connecting transistor
Inventor: ENDO KUNI
IPC: H02M1/08
Filed: 1994-03-23
Abstract: PURPOSE:To provide a small and simplified drive circuit by inserting a current feedback transformer between an emitter terminal to which two transistors are connected and an anode terminal to which two diodes are connected. CONSTITUTION:The current feedback transformer 2 is inserted between the emitter terminals of the transistors 1, 4 and the anode terminals of the diodes 7, 8, and a collector current is fed back to base current supply circuits 3, 6. The base current supply circuits 3, 6 are provided with a function to generate a trigger current when they are turned on, and the one to turn on/off the transistor by inverting the direction of a base current. Since those transistors 1, 4 are prohibited to be energized simultaneously, they can be driven by switching the current fed back by the current feedback transformer 2 by the base current supply circuits 3, 6. In other words, it is possible to reduce two current feedback transistors required in a conventional circuit to one, and also, to feed back the collector current of either transistor and to prowide the small and simplified drive circuit.

Title: Method of controlling load in combined cycle power plant
Inventor: TAKAHASHI MASAE
IPC: F01K23/10
Filed: 1983-03-30
Abstract: PURPOSE:To improve the responsibility to load, by lowering the load on a steam turbine in a preceding manner when an output lowering command is generated, and lowering the flow rate of a fuel while simultaneously increasing the load on the steam turbine after the command load and the actual load coincides. CONSTITUTION:When a load lowering command is generated, the supply of fuel to a gas turbine 3 is made certain, and by opening a steam by-pass valve 13 the load on the steam turbine 6 is started to be lowered. After the command load and the actual load coincides, the load on the gas turbine is lowered, and correspondingly to the lowering the load on the side of the steam turbine 6 is increased. This increase of load is effected by closing the steam by-pass valve 13. Since the decrease in the load on the side of the gas turbine 3 would lower the temperature of the steam generated in the waste-heat boiler, to impart a certain limit to the lowering of the load, the outputs of a pressure detector 15 and a temperature detector 14 of the main steam are compared with the limit value. If one of the outputs reaches the limit value, the lowering of the load is stopped.

Title: Vehicle controller
Inventor: KOMIYA MOTOKI
IPC: G08G1/09
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To properly attain control corresponding to road classification or the like, to attain low fuel expenses and low pollution and to improve traveling performance by inhibiting traveling control corresponding to the detected road classification when the road classification detected from vehicle position data or the like is different from the road classification estimated from the traveling state of a vehicle or the like. SOLUTION: For example, in slope traveling detected by a navigation device 1, the slope traveling judgment of a microcomputer 12 of a traveling vehicle controlling part 2 is detected from the traveling control situation of a vehicle and the actual traveling state. Then, acceleration corresponding to throttle divergence and speed in the actual traveling state is compared with the corresponding value of predicted acceleration in a flat road stored corresponding to the throttle divergence and speed, and when the actual acceleration is more than a prescribed value and larger than the predicted acceleration, this road is judged as a descending slope, and when the actual acceleration is more than the prescribed value and smaller than the predicted acceleration, this road is judged as an ascending slope.  As the result of the judgment, when the traveling state is not the slope (descending slope or ascending slope) traveling, the control of a vehicle for the slope is stopped, and the control of the vehicle for the flat road is obtained.

Title: Disposal of organic waste water
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/30
Filed: 1980-04-22
Abstract: PURPOSE: To facilitate the aerobic biological disposal of organic waste water containing phosphorus especially, by preparatively keeping stock water in an anaerobic atmosphere, and mixing the stock water with separated sludge from the succeeding aerobic biological treatment step.  
     CONSTITUTION: Stock water 1 is introduced into an anaerobic vessel 2, where the stock water 1 is mixed and agitated with return sludge from the final sedimentation pool 7 and kept in an anaerobic atmosphere for a certain period. Outflow water from the anaerobic vessel 2 is biologically treated in a biomembrane vessel 6-1, and introduced into the sedimentation pool 7 where supernatant liquid is drained as purified water 8 outside the system while a part of the precipitated sludge is returned as return sludge 9 to the anaerobic vessel 2, the remainder being discharged as excess sludge 10 outside the system. In this process, the biomembrane coexists with floating sludge fed through the anaerobic vessel 2 in the vessel 6-1. Consequently, the take-up of phosphorus in the vessel 6-1 is facilitated more efficiently, as compared with a case using floating bacteria only. The vessel 6-1 is also applicable in a biological nitrification-denitrfication type.

IPC: C09D5/23
Filed: 1989-03-06
Abstract: PURPOSE:To improve storage property and to prevent increase of dropout by making the surface free energy of the magnetic layer larger than that of a back coating layer by a specified value and specifying the gloss of both layers to specific values. CONSTITUTION:The magnetic layer contains ferromagnetic powder, binder, carbon black, abrasive material and lubricant and is formed on a nonmagnetic supporting body, the other side of which is covered with the back layer containing a binder and carbon black. The surface free energy (SFE) of the magnetic layer is 40 to 55dyn/cm, while the SFE of the back layer is 45 to 55dyn/cm and made larger than that of the magnetic layer by more than 1dyn/ cm. These states of SFE can be realized by using binders having different values of critical surface tension for each layer. The gloss value of the magnetic layer is >150, while the gloss value of the back layer is 2 to 7. This can be realized by subjecting the medium after coating to supercalendering to satisfy the specification.
