Title: Idle air amount learning control device for internal combustion engine
Inventor: HOSOYA HAJIME
IPC: F02D41/16
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To increase the learning frequency as much as possible in a range without mis-learning, at the learning time of the normal deviation of a feedback control amount which is increase/decreased so as to bring an engine speed near a target idle rotational frequency at the idling time. SOLUTION: In the case of an idle rotational frequency feedback control condition (ISC condition; S11), the change amount ΔPd of the refrigerant pressure of an air conditioner is read (S13) and the learning is prohibited when this change amount ΔPd is a prescribed value SL or more and the learning is permitted when it is less than the prescribed value (S14). In the case of the learning permission, the average value ISCave is found out by sampling the feedback control amount ISCI (S16, S17). Based thereon, a normal deviation ΔISC is found out and a learning correction amount ISCLRC is renewed (S18, S19).

Title: Peripheral ground heating device for low-temperature underground structure
Inventor: ANZAI TOSHIAKI
IPC: F17C13/10
Filed: 1985-11-01
Abstract: PURPOSE:To prevent freezing of the ground by interposing a partition pipe concentrically between a protection pipe inserted in an excavating hole and a hot water pipe, thereby to transmit heat of hot water in the hot water pipe to the peripheral ground efficiently. CONSTITUTION:A perforated protection pipe 3 is inserted in an excavating hole B of the peripheral ground A of a low-temperature underground structure, and granular material C such as fine stone or the like is charged between the pipe 3 and hole B. A partition pipe 5 and a hot water pipe 4 are inserted in the protection pipe 3. When hot water is circulated in the hot water pipe 4, underground water between the hot water pipe 4 and the partition pipe 5 is warmed so that the underground water decreases in density. On the other hand, the density of the underground water between the partition pipe 5 and the protection pipe 3 is not so lowered, so that there is a difference in density of the underground water between the inside and the outside of the partition pipe 5. The underground water between the protection pipe 3 and the partition pipe 5 flows in between the partition pipe 5 and the hot water pipe 4 to cause the convection there between, so that heat of hot water circulating in the hot water pipe 4 is efficiently transmitted to the peripheral ground A to prevent freezing of the ground A.

Abstract: PURPOSE:To actively remove the distortion easy to be seen visually and to obtain a video signal excellent in a visual characteristic by providing a means to execute the weighting to cancel the waveform component remoter than the waveform distortion component close to a main signal. CONSTITUTION:The gain of coefficient multipliers CM-C0 and C1-CN to supply the output of respective delaying elements T of a transversal filter 23 is controlled by the value corresponding from a tap gain memory 28. At a subtractor 27, a residual waveform distortion series {eK} is obtained. {eK} and a coefficient group {aK} from a weighting generating circuit 32 are synchronized, inputted to a multiplier 31 and a corrected waveform distortion component [eK]' is obtained. The coefficient group {aK} becomes larger as it is remote from a main signal. A waveform distortion detecting circuit 30 executes the arithmetic processing with a reference signal series {xk} before the resampled waveform equalization and a corrected waveform distortion series {eK}' and a tap gain correcting circuit 29 corrects the corresponding data (gain) of the tap gain memory 28 with the output of the waveform distortion detecting circuit 30.

Abstract: PROBLEM TO BE SOLVED: To provide an image of high quality while sufficiently ensuring the fixability by allowing an image forming means, when a print signal is inputted to start the image formation only when a heating element is heated to a set temperature lower than the set temperature in printing. SOLUTION: The current carrying to halogen heaters 1a, 1b is controlled so that the detected temperature by a pressure roller-side thermistor 5 keeps a set temperature and the fixing roller-side thermistor 5 interrupts printing when the detected temperature reaches a prescribed temperature. When a print signal is received, fixing and pressure rollers are rotated, the temperature control of both the rollers is performed at a first controlled temperature for example, 190 deg.C and a print sequence is waited until the temperature is raised from a standby temperature to a timing temperature, for example, 185 deg.C. When the roller temperature reaches 185 deg.C, the print sequence is started. Just after it, the heat of a heater, which is full lighted, is taken by paper passing, and the roller temperature falls to about 170 deg.C.  At this time, a second controlled temperature is switched to control the rollers at 170 deg.C.

Abstract: PURPOSE:To implement a sufficient process speed regardless of a relative position relation of a gas pressure distribution to a beam scanning range by specifying an angle to a processed sample surface of an opening surface of a nozzle for beam induction process for introducing a reactant gas into a processed surface. CONSTITUTION:In a focused ion beam deposition method or a focused ion beam induction etching method, an angle to a processed sample surface 5 of an opening surface of a nozzle 1 for beam induction process for introducing a reactant gas into the processed surface 5 is set to 60 to 80 degrees. In the angle range, a gas pressure distribution 2 on the sample has a good uniformity and a large pressure value can be obtained in the range of beam irradiation without increasing a gas flow as compared with the case of an angle setting other than above angle. Also, since the uniformity of the distribution is excellent, the change in distribution to the slight deviation from a nozzle angle or a set point of distance is small and the margin to a set error can be increased.
