Title: Failure diagnosing device for exhaust gas reflux device
Inventor: OONAKA HIDEMI
IPC: F02B77/08
Filed: 1994-12-07
Abstract: PURPOSE: To correctly detect the degree of clogging in an EGR passage by gradually opening an EGR control valve from the valve closed state to increase an EGR reflux flow quantity when the operating condition is the fuel supply stop condition to decrease the speed, and detecting the on-off condition of a pressure switch to make a dignosis for failure. CONSTITUTION: A failure diagnosing device is provided with a pressure switch 70 operated when the negative pressure in an EGR passage 8 on the exhaust side from an EGR valve interposed in the EGR passage 8 exceeds a designated value, and a valve opening measuring means 30 for measuring the valve opening state of the EGR valve 9. When the engine operating condition is the fuel supply stop to decrease the speed, the EGR valve 9 is gradually opened, and when the pressure switch 70 is not switched in the case of a small valve opening in the course of opening the valve, clogging in the EGR passage 8 is decided to be large. When the pressure switch 70 is switched, clogging is decided to be small. Further, in the similar fuel supply stop condition, when the opening of the EGR valve 9 is large, if the pressure switch 70 is switched, it is decided to be normal.

Title: Production of germanium lens
Inventor: NAKAMURA KUNIO
IPC: G02B3/00
Filed: 1986-12-19
Abstract: PURPOSE:To eliminate the need for polishing a lens surface and to produce a germanium lens with high efficiency by melting a germanium material, casting the melt thereof into a lens casting mold finished to a specular surface and cooling the melt. CONSTITUTION:The air atmosphere in a chamber is replaced with nitrogen and a specified amt. of the purified Ge material is heated and melted in a nitrogen atmosphere. The liquefied Ge material is then cast into the lens casting mold which is heated to the same temp. and is finished to the specular surface. The gaseous nitrogen is evacuated to reduce the degree of vacuum down to <=10<-1>Pa so that the Ge liquid is defoamed. After the liquid is held in this state for the prescribed time, a plunger die finished to a specular surface is pushed into the casting mold and the temp. is gradually lowered until the room temp. is restored. The molded Ge material is then taken out. The Ge lens which does not require surface polishing is thereby produced with the high efficiency and the production cost is reduced.
