Title: Controlling method for composition of multielement mixed crystal semiconductor
Inventor: ONABE KENTARO
IPC: H01S5/00
Filed: 1980-08-13
Abstract: PURPOSE:To obtain the optimum liquid phase composition of a multielement mixed crystal semiconductor for the epitaxial growth of the semiconductor with the least number of times of times of experiments by clarifying the two variables representing the characteristics of the crystal and the two variables representing the lipuid phase composition in the relationship of 17 types. CONSTITUTION:The control of the composition of the III-V group compound semiconductor of the multielement mixed crystal mode of In1-xGaxAsyP1-y in the liquid epitaxial growth can be carried out merely by observing the relationship between the crystal lattice constant a0 of the crystalline characteristics of the liquid phase composition (XGaLXASL) and the enargy gap wavelength lambdaG(a0, lambdaG). Since it can discover the crossing point A of the equal lattice constant line and the equal wavelength line corresponding to DELTAa=0 and DELTAlambda=0 on th equi-temperature plane, it will discover the shade A' of the point A on the (XGaL-XASL) plane. Since this relationship can be sorted to 17 types, they can be sequentially examined. In this manner, the composition can be readily controlled.

Title: Model estimation controller
Inventor: OYA JUNKO
IPC: G05B13/02
Filed: 1990-05-01
Abstract: PURPOSE:To eliminate the interruption of the estimation control by reducing gradually the control request conditions until a second optimum manipulated variable when the solution of an optimum manipulated variable that satisfies temporarily the limit conditions can not be obtained. CONSTITUTION:A future value estimating means 1 obtains the estimation formulas for the future values of a controlled variable (y) and a manipulated variable (u) based on a model obtained by approximating the dynamic characteristic of a control subject and sets the limit conditions related to the future values of both variables (y) and (u) together with the evaluation functions of the secondary forms related to the future values of the variable (y) estimated by the estimation formula, the deviation against the target value (r), and the future value of the variable (u) respectively. Then the means 1 calculates the future value of the variable (u) by a secondary plan method in order to satisfy those set limit conditions and also minimizes the evaluation function. If the evaluation function includes no enable solution, the conditions concerning the control request are least changed for the time being only at that time point in order to obtain a second optimum solution. Therefore the conditions are gradually reduced until the second optimum solution (manipulate valiable) is obtained in regard of such control requests for the limit conditions, the evaluation function, the target value, etc. Thus the estimation control is never interrupted.

IPC: F02D41/00
Filed: 1983-06-22
Abstract: PURPOSE:To improve the driving performance on acceleration run while relieving a driving shock by correcting the quantity of fuel based on a quantity increasing correction value for acceleration which is read out from the detected values of a throttle valve opening and the number of revolution of an engine at the time of detecting the accelerating running condition. CONSTITUTION:A throttle valve opening value thetan at the time of inputting each TDC signal is read in, while the previous valve opening value thetan-1 is read out, from a RAM 508, and the difference DELTAthetan in the valve opening between this time and the previous time is calculated. When the result is greater than the specified negative synchronous speed reduction judging value G, judgement is made that processing for acceleration is not being carried out, and, if the fuel feed was not being cut off at the previous time, judgement is made that the absolute pressure PBn-1 in a suction pipe at the previous time was lower than the upper limit value PBACC for which quantity increase for acceleration should be carried out. And, if the valve opening value thetan-1 is smaller than the upper limit value thetaACC for which speed increase by acceleration should be carried out, judgement is made that the driving condition at the time immediately before is not in a high- load driving condition and, further, when the driving condition is in an accelerating condition and not in a cool time, a correcting table is selected. The table is made to correspond to more than one area that are based on the valve opening thetan and the number of revolution value Ne, setting a quantity increasing correction value adapted to an anticipated running condition.

IPC: H01Q15/14
Filed: 1987-05-11
Abstract: PURPOSE:To improve the acquisition efficiency of a radio wave by bonding a reflecting member made of a thin plate with a thin metallic film formed thereupon to a base of a reflector main body. CONSTITUTION:For example, a glass-made or plastic-made thin plate 43 is used and a thin metallic film 44 is adhered (vapor-deposited) onto the thin plate 43, then the surface accuracy as high as making it possible to be used as a mirror is obtained. Since the thin plate 43 has rigidity by itself, even when a parabolic face of the base 41 has local unevenness, the adhesion 42 in following to the local unevenness does not take place, the unevenness is overcome and the face accuracy of the base plate 41 or over is attained. Moreover, the reflecting member (thin plate 43 with thin metallic film 44 formed thereupon) is a better conductor than carbon cloth and excellent in the reflecting efficiency. Thus, the reflecting efficiency of the reflector is improved and the acquisition efficiency of radio wave is enhanced.

Abstract: PURPOSE:To maintain a quantity of ejection from a nozzle of an ejector consstant by disposing a valve means which is controlled to present a proper opening that demanded flow may be maintained in spite of variation in primary pressure between a separation point of a pressure passage and the ejector. CONSTITUTION:A control valve 10 is disposed in a circulation passage 3 between a separation point of a pressure passage 5 and an ejector 2. The first detector 8 for detecting pressure is disposed in an inflow passage 4 and the second detector 9 is disposed at the lower site of the control valve 10 in the circulation passage 3. The control valve 10 is controlled to present a proper opening that a difference between pressures by both detectors 8 and 9 may be maintained to give a constant demanded value. Even if a preset value of a primary pressure regulation valve 6 is modified to result in variation in pressure at the discharge side of a pump 1 in the circulation passage 3, a difference between pressures at primary and secondary sides of a nozzle of the ejector 2 is maintained to have a constant demanded value. Hence, ejection from the nozzle of the ejector 2 may be maintained constant without fluctuation in quantity.
