Patent JP-H06232229-A (JP)
Title: Defect inspection method and device thereof
Inventor: MARUYAMA HIROSHI
IPC: G03F1/84
Filed: 1993-02-04
Abstract: PURPOSE:To promptly inspect a defect which actually obstructs a mask reticle by detecting a defect by way of the comparison of a circuit pattern on a board with the other circuit pattern and determining the presence of the defect which affects the characteristic of a defective circuit in reference with a circuit around the defective parts. CONSTITUTION:The light discharged from a light source 1 is condensed by way of a group of lenses 31 and 32 permeating circuit patterns 21 and 22 and converted into an electric signal by light receiving elements 41 and 42 where a signal processing circuit 5 turns the signal into image data intended for inspection and forces an image memory 6 to store the data as a pit map. A defect detection circuit 7 compares the stored image data intended for inspection with the image data intended for comparison and detects a defect which exceeds a specified size. If the detected defect is small, it will not be stored in a defect memory 9. When one side of a frame responds to a change in black and white, even a small defect produces a trouble to the circuit and it is stored in the defect memory 9, thereby reducing inspection time.

Title: Ram rocket
Inventor: KUBOTA NAMINOSUKE
IPC: F02K7/18
Filed: 1991-02-12
Abstract: PURPOSE:To increase the specific impulse by furnishing a gas generative agent which causes outflow of high temp. gas to a ram combustion chamber when sustainer propellent is in combustion. CONSTITUTION:When a combustible gas is ignited, a gas generative agent 8 is ignited by an ignitor 9 to generate a high temp. gas, which is injected to the port part of an air intake 6 lying upstream of a ram combustion chamber 3 through a nozzle 10, and thereby a high temp. region is formed upstream of the ram combustion chamber 3. Even though boron unlikely to combust is contained as a metal fuel in a sustainer propellent 12, the combusting efficiency can be enhanced by promoting combustion of the boron, wherein it involves no risk of exhaustion of the residual borron from combustion to the outside, which permits the metal fuel to work while exerting its full characteristics. This enhances the specific impulse due to combustion of the sustainer propellent 12.

Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for controlling an air-fuel ratio and a method for measuring an air-fuel ratio whose structure is simple and whose circuit can be simplified. SOLUTION: A signal from a λ. sensor is read in step 100. It is judged on the basis of the read signal in step 110 whether an air-fuel ratio of a gas to be measured is rich or lean. When the air-fuel ratio is judged to be rich, a minute voltage is impressed in a minus direction in step 120. On the other hand, when the air-fuel ratio is judged to be lean, the minute voltage is impressed in a plus direction in step 130. A pump current flowing according to the voltage impressed in each direction is measured in step 140. The air-fuel ratio is roughly obtained from the measured pump current in step 150. A voltage corresponding to the rough air-fuel ratio is impressed to a pump cell in step 170. The pump current is measured in step 180 and, a correct air-fuel ratio is obtained from the pump current in step 190.
