Title: Exhaust gas recirculation device
Inventor: SHIBATA MASAHITO
IPC: F02B37/22
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent exhaust gas from being excessively recirculated when the abnormality of opening valve fixing is generated on an exhaust gas recirculation valve, concerning an exhaust gas recirculation device for partially reciculating exhaust gas of an internal combustion engine to an intake passage. SOLUTION: An exhaust gas recirculation valve 80 is interposed in an exhaust gas recirculation passage 78 for communicating an exhaust passage 68 and an intake passage 52 with each other. An intake throttle valve 58 is provided inside of the intake passage 52. An exhaust turbine 70 of a variable capacity turbocharger 62 is communicated with the exhaust passage 68. When the actual opening of the exhaust gas recirculation valve 80 is larger than the target opening, it is judged that the abnormality of opening valve fixing is generated. When abnormality of opening valve fixing is detected, the intake throttle valve 58 is full opened regardless of the operating state of an internal combustion engine 10, and the variable capacity turbocharger 62 is so controlled that the flowing resistance of the exhaust turbine 70 may be minimum.

Title: Database processor and storage medium
Inventor: YAMAGUCHI TAKESHI
IPC: G06F17/30
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To easily cope with a database even when the structure of the database is changed by providing a model retrieval sentence storing part which stores a retrieval sentence of a database that includes variable and a means which replaces the variable of a retrieval sentence which belongs to a model retrieval sentence storing part and corresponds to a retrieval item with a value that is inputted by a person who retrieves and generates a retrieval sentence. SOLUTION: An input form storing part 40 stores an HTML(hypertext markup language) document. When clients 6 and 7 make a retrieval request, an HTML document in an input form into which a stored retrieval condition is inputted is sent to the clients 6 and 7. A concrete structure with a model retrieval sentence storing part 30 stores a model SQL sentence that corresponds to a retrieval item, the model SQL sentence has variable, and a retrieval sentence is generated by replacing the variable with the value with which a retrieval sentence generating means 13 is inputted by the clients 6 and 7. Thus, execution efficiency is improved.

Title: Controller of thyristor inverter
Inventor: MIYAHARA YOUJIROU
IPC: H02M1/096
Filed: 1980-01-17
Abstract: PURPOSE:To shorten the calculating time of a firing angle and improve the accuracy of ignition control by a method wherein master and slave thyristor inverters are connected with each other in an antiparallel mode with the firing angle on the slave, side kept constant, and the relation between the master and slave is changed over when the output current on the master side becomes lower than the circulating current set value. CONSTITUTION:A pair of thyristors 4, 5 are connected in an antiparallel mode and their AC sides are connected to an AC power source 1. The AC output voltages of the inverters 4, 5 are generated to a load 8. The current flowing in the inverters 4, 5 and the load 8 is detected by transformers 6, 7, 9 separately, and each current is inputted to a microcomputer 10 to compute the firing angles of the inverters and add the outputs to automatic pulse phase shifters 11, 12. At this time, the firing angle of the inverter on the slave side is kept constant, and the relation between the master and slave is reversed when the output of the master inverter becomes lower than the circulating current set value. By so doing, calculation time is shortened, while ignition control can be carried out with higher accuracy.

IPC: F03B17/06
Filed: 1982-01-16
Abstract: PURPOSE:To increase stream energy by providing a bypass pipe communicated to the part where a passage is narrowed and branched off from the passage upstream of the narrowed part. CONSTITUTION:A pipe passage is narrowed at a part 2 just before which the pipe has a wide passage 1. A bypass pipe 4 is arranged between the passage 1 and the narrowed part 2 for communicating therebetween. If no bypass is provided, the following equation is formulated due to Vernoulli's theory: V<2>1/2g+ P1/gamma=V<2>2/2g+P2/gamma, where P1 and V1 are pressure and velocity of stream in a passage 1, respectively, and P2 and V2 are pressure and velocity of stream in the narrowed part 2. However, due to the provision of the bypass passage 4, the following condition is established since P1=P2 but V1<V2 (due to the provision of the narrowed part 2): V<2>1/2g+P1/gamma=V<2>2/2g+P2/gamma, threby it is said that the energy of stream may be increased.

IPC: G01N25/60
Filed: 1984-01-11
Abstract: PURPOSE:To measure wetness simply, by heating the inside of a measuring container, converting wet steam to be measured into overheated steam, thereby heating the wet steam to be measured by a simple constitution. CONSTITUTION:All valves 7-9, 13 and 14 are opened, and wet steam to be measured is made to pass into containers 1 and 2. Then, the valves 13 and 14 are closed and the wet steam to be measured is stored in the containers 1 and 2. Thereafter the valve 8 is closed. Then, the wet steam in the container 1 is heated by an electric heater 17 and made uniform by an agitator 16. Thus the volume is expanded. At this time, the valves 7 and 9 are opened. Therefore, the pressure in the containers 1 and 2 is not changed. A piston 18 is slid in a cylinder 3 in the direction toward the container 2. An external magnetic body 20 is displaced together with the piston 18 owing to the magnetic coupling with an internal magnetic body 19. The displacement is detected by a variable resistor 22 and inputted to a microcomputer 23. The amount of volume expansion is computed from the input value, and the wetness is measured.

Title: Error correction/transmission device
Inventor: TSUJIMOTO ICHIRO
IPC: H04L5/06
Filed: 1993-01-14
Abstract: PURPOSE:To ensure the desired correction ability of an error correction/ transmission device without increasing a signal band. CONSTITUTION:The same time length is secured by a velocity converter 22 between the check and data bit trains, and both bit trains are modulated by the modulators 25 an 23 respectively. A notch filter 26 fades the center frequency of the data bit modulated wave. This data bit modulated wave is synthesized with the check bit modulated wave by a synthesizer 27 and transmitted as a transmission signal. This signal is received at a receiving part as a detection signal which is turned into a decided data bit train by a decision feedback type equalizer 34. Then a BPF 32 and a demodulator 33 acquires a decided check bit train from the detection signal. A velocity conversion multiplexer 40 applies the velocity conversion to both decided data and check bit trains and then multiplexes these bit trains into a reception block code. Then an error corrector/decoder 41 performs the correction of errors.
