Title: Continuous preparation of trimellitic acid
Inventor: SUEMATSU MASAAKI
IPC: B01J23/84
Filed: 1981-04-09
Abstract: PURPOSE: To prepare the titled compound, in high purity and yield, by the two- stage continuous oxidation reaction of pseudocumene at a specific temperature using a catalyst comprising Co, Mn and Br at a specific concentration, keeping the concentration of the raw material in the produced liquid at the first stage below a specific level.  
     CONSTITUTION: Trimellitic acid is prepared by the continuous oxidation of pseudocumene with an O 2 -containing gas in an acetic acid solvent in the presence of a catalyst composed mainly of a Co compound, an Mn compound and a bromine compound. In the above process, the first stage reaction is carried out at 120W180°C keeping the amount of Co to 0.01W0.09wt% of the acetic acid solvent, that of Mn to 1W50wt% of Co, and that of Br atom to 6W20 times the weight of Co, and reducing the concentration of the residual pseudocumene in the produced liquid to ≤0.4wt%. After adjusting the concentration of Mn to 15W50wt% of Co, the second oxidation reaction is carried out at 180W230°C. The deactivation of the catalyst can be effectively prevented.

Title: Electronic control device of internal-combustion engine
Inventor: SUZUKI YOSHIO
IPC: F02D41/26
Filed: 1985-03-18
Abstract: PURPOSE:To prevent a decrease of engine performance in abnormality time, by performing an action control, when one of the first and second counters, respectively supplying engine speed parameters to the first and second central processing units, is in abnormality, using the other counter. CONSTITUTION:An electronic control device, inputting parameter values in proportion to the inverse number of an engine speed respectively from Me counters 29, 24 to the first CPU1 controlling the fuel supply and the second CPU2 controlling the ignition timing, stores each mean value in a RAM12. And when an engine is in completion of warming further in idle speed operation, the control device, checking abnormality of the both Me counters 24, 29 by comparing them with the stored value of the RAM12, decides the counter to be abnormal if a compared difference increases to a predetermined range or more, for instance, when the Me counter 29 is decided to be abnormal, the CPU1, 2 respectively execute an action control by an output of the normal Me counter 24. In this way, a substantial decrease of engine performance can be prevented even in trouble time.

Filed: 1983-03-29
Abstract: PURPOSE:To form highly accurate pattern by reversely distorting a pattern to the intrinsic transfer distortion of the transfer apparatus in the case of forming a transfer pattern on the mask material with an electron beam exposing apparatus. CONSTITUTION:Before delineation to a belt shaped region, the transfer distortion compensating data of the belt shaped region is transferred to a transfer distortion compensating data memory 22 of a deflection control circuit 11 from a magnetic disk 21 of a computer system 9. Then, a synchronous signal Q for starting deflection is sent from a stage location measuring apparatus 12 and thereby the ruster scanning is carried out. Here, compensation of transfer distortion is carried out by compensating the deflection starting position. Compensating data of transfer distortion is generated for each small region in unit of deflection of N times. The small region exposed first is read previously from a memory 22 and is then held in a latch circuit 24. An address counter 23 is updated by such synchronous signal of N times and the next compensating data is read.

Title: Method and device for measuring flow velocity of liquid, particularly, water
Inventor: SEPAE HAIKI
IPC: G01F1/58
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To measure the flow velocity of a liquid, particularly, water, by a magnetic flow measuring method, by measuring only a component having the same phase as that of the magnetic field from the sinusoidal wave voltage generated on an electrode. SOLUTION: A micro-processor 8 generates a square signal transmitted to a tuning coil 10 via a filter 9. The magnetic field is converted into the sinusoidal wave by the filter 9 and tuning coil 10. The current consumption of a device is reduced by tuning. The flow of the liquid of a liquid current pipe is measured based on the potentials given by electrodes 12, 13. The electrode potentials are amplified by a differential amplifier 14 and sent to an A/D converter 15. The intensity of the magnetic field is measured by a magnetic field measuring coil 16, and the voltage proportional to the induction of the magnetic field is amplified by an amplifier 17 and sent to an A/D converter 18. The phase is detected by the micro-processor 8 by the mathematical method.  When both reference voltages of the A/D converters 15, 18 are equal, the final result does not depend on the drift of the reference voltages.

Title: Electronic tuning polar filter
Inventor: MATSUO MICHIAKI
IPC: H03H11/04
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide a small sized electronic tuning polar filter that has a steep attenuation pole in the vicinity of a pass band and where the position of the attenuation pole is controlled electronically. SOLUTION: An auxiliary circuit 110 consisting of cascade connection of a variable phase shifter 102 whose phase shift amount is adjustable and a variable attenuator 103 whose attenuation is adjustable is connected to a band pass filter 101 via connection circuits 104, 105 respectively and the phase shift amount and the attenuation are controlled electrically by employing active elements for the variable phase shifter 102 and the variable attenuator 103. An attenuation pole of the title filter is caused at a frequency at which an amplitude of a signal from an input terminal 106 to an output terminal 107 via the band pass filter 101 is the same as an amplitude of a signal from the input terminal 106 to the output terminal 101 via the variable phase shifter 102 and the variable attenuator 103 and a phase of the former signal is opposite to a phase of the latter signal.  Since the phase shift amount and the attenuation are controlled electrically, the frequency at which the attenuation pole is produced is easily adjusted. Moreover, circuit integration is possible for the variable phase shifter 102 and the variable attenuator 103 and then they are made small.

Title: Control device of automatic transmission having manual gear shift input
Inventor: TAKI MASAHARU
IPC: F16H61/04
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To restrain a rapid change and an acute rising of output torque by correcting a target input rotating speed to the deviation generating side so as to reduce the operating fluid pressure to an engaging friction element when a deviation between the target input rotating speed and an input rotating speed becomes large by a manual gear shift mode control means. SOLUTION: An A/T control unit 20 sets a value by adding a time integral value of an input rotating speed deviation initial value to a present value of an initial target input rotating speed to a present value of a new target input rotating speed when input power from an engine 1 is high since an engine speed of the engine 1, that is, an input rotating speed is largely high or when a vehicle speed is relatively small. Therefore, a deviation between a target input rotating speed and an actual input rotating speed reduces, and output torque slowly reduces. Therefore, according to this processing, the output torque does not largely and rapidly change during a manual up-shift, so that a speed change shock is not caused.
