Title: Apparatus for inspecting oil leakage of vehicle unit
Inventor: ODERA NOZOMI
IPC: G01M3/26
Filed: 1984-12-25
Abstract: PURPOSE:To inspect the oil leakage of a vehicle unit within a short time with high accuracy, by judging the airtightness degree of a vehicle unit on the basis of desired holding pressure held for a set time or not. CONSTITUTION:In performing the inspection of the oil leakage of a transmission unit 10, air with predetermined pressure is at first supplied to air pipes 12, 11 and air entering the air pipe 11 is supplied to the transmission unit 10. The air pressure of the air pipe 12 is converted to an electric signal by a pressure sensor 3 to be inputted to a tester 5 through an amplifier 4. By this process, the indicator 5b of the tester 5 is rotated to a clockwise direction to move to a position of a point Q. Because this point Q corresponds to the upper limit of air pressure in the transmission unit 10, an air solenoid valve 7 is automatically operated, when said indicator 5b reaches to said position, to stop the communication of an air supply source 6 and a pressure reducing value 8. If the holding pressure in the transmission unit 10 is held for a set time or more in this state, the judgement of acceptance is performed.

Title: Dry etching method
Inventor: IZAWA MASARU
IPC: H05H1/46
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To allow machining with a contact hole of high aspect ratio and an oxide film which requires high selective ratio relative to a silicon nitride film, by forming a plasma region different in electron temperature and controlling F relative to CF2 in plasma and ion generation amount independently. SOLUTION: With an etching device which uses electro-cyclotron resonance(ECR), the electron temperature is high in the ICR region (high electron temperature region 103), while a low electron temperature region 102 is formed at other part. The ECR region becomes narrower when a magnetic field gradient applied from the outside is larger. So, by controlling the magnetic field gradient of ECR region, F/CF2 generation ratio is varied. In a state with small magnetic field gradient, F/CF2 generation ratio is small while with large magnetic field gradient F/CF2 generation ratio is large. Thus, etching with an oxide film of high selective ratio relative to a resist or nitride film is possible.
