IPC: B28B11/02
Filed: 1990-08-31
Abstract: PURPOSE:To prevent defective articles from being generated due to cracking, deformation or the like and raise the yield by injection-molding segments of a component part individually, degreasing the molded segments individually, assembling the degreased segments together, and hydrostatically pressing the assembled segments to unite the segments, followed by sintering. CONSTITUTION:An injection-molding material comprising a kneaded mixture of a ceramic powder and a polymeric material such as a thermoplastic resin is injection molded, for example, into a vane part and a shaft part of a ceramic turbocharger rotor. The vane part and the shaft part are degreased individually. The vane part and shaft part thus degreased are assembled together, and after application of a latex rubber to the surface of the assembly, the vane and shaft parts are united by pressing at a predetermined hydrostatic pressure. The united assembly is then sintered, to obtain the ceramic turbocharger rotor. It is, thereby possible to enhance the yield at each of the molding, degreasing and sintering steps.

IPC: G11B7/085
Filed: 1988-09-13
Abstract: PURPOSE:To stabilize the lead-in operation of a servo by changing a coefficient so that a phase margin of an equalizer characteristic may be larger in an intermediate band compared with a prescribed characteristic immediately after loop closing, and the prescribed characteristic may be obtained after a prescribed time with the gradual increase of a gain in the intermediate area according to time passage. CONSTITUTION:A controller 15 makes the characteristic of an equalizer 8 into that having the larger phase margin in the intermediate band at the time of the servo loop closing, namely at the time of a lead-in start, and changes the coefficient to determine the characteristic of the equalizer 8 so that the gain in the intermediate band may gradually increase according to the time passage and may return to the characteristic at the time of normal performance after the passage of a lead-in time. Consequently, since the characteristic having the sufficiently large phase margin in the intermediate band in the initial stage of the lead-in can be obtained, overshooting at the time of the lead-in can be sufficiently suppressed. Thus, the lead-in operation can be stably and surely attained.

IPC: F02D41/40
Filed: 1983-12-05
Abstract: PURPOSE:To devise improvement of cold state operating performance of an engine without accompanying occurence of idling noise (Diesel knock) by correcting fuel injection timing according to the warmed up state of the engine when the engine is in the condition of acceleration or no-load racing. CONSTITUTION:While an engine is operating, an electronic control circuit 4 takes in each signal from a cooling water temp. sensor 71, an engine rotational speed sensor 41, an accelerator position sensor 72, a suction pressure sensor 73, etc. The control circuit 4 also judges whether the engine is in acceleration or no-load racing from the variation ratio of the accelerator position sensor 72 output.

The correction value is made large when the engine is cold and made small after it is warmed up. The control circuit 4 further calculates the time of basic injection period based on the engine rotational speed and the accelerator position, corrects the time of basic injection period by the lead angle value DELTAT, controls a pressure adjusting valve 18 by the injection period time corrected as above, and controls the position of a timer piston.

Title: Developing device
Inventor: TADA TATSUYA
IPC: G03G15/08
Filed: 1985-10-17
Abstract: PURPOSE:To make the ratio of toner and carriers nearly constant and to obtain an image with proper density at any time by arranging two detection electrodes so that there is a developer interposed between both detection electrodes when the developer exceeds a proper amount and causing periodical vibration by the voltage induced between both electrodes. CONSTITUTION:When the amount of toner is proper, there is no developer present between the detection electrodes 15 and 16 and a sensor potential has a constant value. Further, the amount of toner begins to increase from the proper amount, the developer begins to interpose between the electrodes 15 and 16 and the dielectric constant between the electrodes 15 and 16 increases abruptly, so that the sensor potential drops speedily. On the other hand, the sensor potential vibrates periodically owing to the ration of the detection electrode 16, but the amplitude of this periodical vibration is relatively small when the amount of the developer is proper and becomes maximum when the developer begins to increase in amount from the proper amount. For the purpose, the amplitude of the periodical vibration of the sensor potential is detected and then the supply/stop period of toner is known accurately without being affected by a shift in the sensor potential due to the electrostatic charging of a deice body.

IPC: H04N1/41
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To both reduce the amount of data by compression and shorten the time required for data reference. SOLUTION: When document data 100 are stored, a position where compression should be started is detected from the data string of the document data 100 and only the data behind the detected position are compressed by a data compression part 23. Consequently, compressed document data 200 which do not have data of the 1st page compressed and has only the data of the 2nd and succeeding pages compressed are generated. Therefore, the data of the 1st page need not be expanded when referred to and both the reduction of the amount of data by compression and the shortening of the time required for data reference are possible.

Title: Universal electrostatic puri- fication of exhaust gas contain- ing dust and pollutant and its device
Inventor: KAARU SHIYUTAINBATSUHAA
IPC: B03C3/53
Filed: 1990-08-31
Abstract: PURPOSE: To suppress content of pollutant in an exhaust gas at a value which is remarkably lower than an allowable limit in a clean gas by collecting a fluid supplied in a second stage to top ends of collecting electrodes under the lower ends thereof, then discharging the fluid from a filter and feeding dry dust collected in the second stage to a dust receiving means. CONSTITUTION: The liquid supplied in the second stage 2 to the top ends of the collecting electrodes 3b is collected under the lower ends of the collecting electrodes 3b, then is discharged from the filter in a horizontal direction and the almost dry dust further collected in the second stage 2 is fed to the dust receiving means 5b. By this constitution, pollutant in the exhaust gas is not blended with almost dry dust further collected in the second stage 2 and the pollutant together with the dust is not discharged from the filter. Consequently sludge which contains the pollutant sand is difficult to treat is not generated in the second stage 2. As the dust and the pollutant are suitably collected, content of the pollutant in the exhaust gas can be suppressed at the value which is remarkably lower than an allowable limit in the clean gas.
