Abstract: PURPOSE:To make it possible to check a monitor system readily without complicated work with special devices by maintenance personnel by utilizing a transmitter in a reserve system or in an operating system, and outputting simulated abnormal signals for checking the monitor. CONSTITUTION:When a starting signal is outputted in a rest period of each ground apparatus, a controller 3 sends control signals to transmitters 1a and 1b in an operating system and a reserve system and an antenna control part 5 so that a normal radiowaves can be emitted at specified timings. The transmitters 1a and 1b are controlled so as to generate simulated abnormal signals exceeding an alarm limit during the rest time of the transmission. The signals are supplied to synthesizers 21-23 and a simulated load resistor 19 through an RF switch 2a and a directional coupler 20. The simulated abnormal signals sent to the synthesizers 21-23 are detected in RF detectors 7-9 and sent to a monitor 6. When the monitor system is normal, the simulated abnormal signals are detected, and an alarm is outputted. Thus the monitor system of the ground apparatus of a microwave landing system is confirmed. Then, parameters are sequentially confirmed, and the checking of the monitor system is completed.

Abstract: PURPOSE:To provide stable control by a less-expensive optical sensor by a method wherein an integral value of differences in respect to a mean value within a desired time of a moving mean value calculated from an optical power signal is calculated and an output for eliminating a difference in respect to a differential integral value corresponding to a suitable O2% for a present fuel flow rate is given. CONSTITUTION:Initial set values (a measuring period DELTAt of an optical power level, a moving mean time t1 second and the like) are inputted, a total value of data is calculated to calculate a mean value. Next optical power level data is taken, and a moving mean value is calculated. Integrated difference value is calculated, a correction for the difference value is outputted, a data area for the time counter correction is reset and this processing is repeated. The correction is inputted to an adjusting unit 19. The adjustor 19 receives a flow rate signal Q to be outputted from a fuel flow meter 8, calculates a corresponding difference integral value of the most suitable O2% and calculates a difference B between the present value and the most suitable value. Further, the adjustor 19 corrects the above B, calculates an amount of air getting the most suitable combustion state and outputs it to an adjusting valve 9.

Title: Inspection method for bump electrode
Inventor: OSUMI TAKUJI
IPC: H01L21/321
Filed: 1986-10-22
Abstract: PURPOSE:To reduce the inspection time sharply by forming a pattern which can display a maximum diameter required to obtain the prescribed height of a bump electrode. CONSTITUTION:A concentric pattern 15 is formed at the circumference of a connection part 14 between a bump electrode 13 and a device surface 12. The pattern 15 is formed on the basis of a correlation of the height H2 of the bump electrode 13 on the device surface 12, the maximum diameter L1 of the bump electrode 13 and the diameter L2 at the connection part 14; it is approximately (L2/2)<2>=(L1-H2)H2; the diameter L2 of the connection part 14 becomes a constant. Accordingly, the maximum diameter L1 becomes a function of the height H2 only. If the maximum diameter L1 of the bump electrode 13 is within the width B1 of the pattern 15, its height H2 is within a permissible range. By this method, it is possible to execute an accurate inspection in an extremely short time.

IPC: F16H61/02
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To lessen the driving sound of an actuator before the rotation operation and quickly operate an automatic transmission after the rotation operation of the engine by setting the electric current supplied to an actuator to be a prescribed value in the case an in internal combustion engine and a vehicle are stopped. SOLUTION: Whether an internal combustion engine is rotated or not is judged (S12). In the case the engine is not rotated, whether a vehicle is stopped or not is judged (S14). In the case the vehicle is stopped, the electric current value to be supplied to the actuator is controlled to be a prescribed waiting electric current value α(S16). In other words, the electric current value is controlled to be a value, for example 0.2A, at which the driving sound is small and shift operation can smoothly be carried out following the rotation of the internal combustion engine. On the other hand, during the rotation of the internal combustion engine or during the driving of the vehicle, the value of the electric current to be supplied to the actuator is set to be a value corresponding to known shift operation (S18).  Consequently, the operation sound of the actuator is lowered and the calmness is retained and moreover, at the time of starting the rotation of the engine, the operation of the automatic transmission can smoothly be started.
