Abstract: PROBLEM TO BE SOLVED: To produce a dense MgO film, excellent in orienting properties and having a small crystal grain diameter by forming the MgO film on a substrate in the presence of a plasma in an atmosphere containing H in an excited or an ionized state. SOLUTION: A substrate 8 is attached to a rotatable substrate holder 2 installed in the upper part of a vapor deposition chamber 1 and a granular MgO 6 is then placed in a crucible 5 arranged at the bottom of the vapor deposition chamber 1. The interior of the chamber 1 is subsequently evacuated to 10<-5> to 10<-6> Torr and a current is then made to flow through heaters 11 to heat the substrate 8 at a prescribed temperature. An inert gas for generating a plasma is subsequently fed from a discharge gas feed port 10 of a pressure gradient type plasma gun 3 thereinto to regulate the internal pressure to 10<-3> to 10<-4> Torr. A reactive gas is then fed from a feed port 9. A voltage is subsequently applied from a DC power source 4 across the plasma gun 3 and the crucible 5 to thereby carry out the regulation so as to provide 100-150 A discharge current.  H2 gas is then introduced from the feed port 9 or 10 thereinto to converge a plasma stream 7 on the crucible 5. Thereby, the MgO 6 is evaporated to form the MgO film on the substrate 8.

Title: Intake device of combined supercharge engine
Inventor: KAKIUCHI TOSHIAKI
IPC: F02B37/04
Filed: 1989-05-30
Abstract: PURPOSE:To prevent oil from being sucked out from a compressor housing by communicating the compressor intake flow passage of a turbo charger to the dischage passage thereof with a bypass passage having a valve device. CONSTITUTION:A compressor 10 of turbo charger 3 and a supercharger 5 are connected to the intake side of an engine serially in order from the upstream. The intake and discharge passages 6,7 of compressor 10 are communicated by a bypass passage 12. At a bypass passage 12, a valve device 13 is provided, which is normally closed, but is opened to open the bypass passage 12 at the time when the pressure of the discharge flow passage 7 of the compressor 10 is less than a specified pressure. Consequently, when supercharging work is not performed substantially at the time of low rotation of an engine 1, and pressure of the discharge side flow passage 7 is less than the specified pressure, the bypass passage 12 is opened by the valve device 13. Thereby, since intake air is passed through the bypass passage 12, oil is prevented from being sucked out owing to negative pressure from a housing of the compressor 10.
