Title: Misfet device and manufacturing method thereof
Inventor: ABIKO HITOSHI
IPC: H01L21/336
Filed: 1992-01-30
Abstract: PURPOSE:To shallowly distribute the impurity for threshold value adjustment by a method wherein gallium in specific concentration is contained in the part near substrate surface in a channel formation region. CONSTITUTION:Within the title MISFET formed on one main surface of a single crystal silicon substrate 101, gallium in the peak concentration of not exceeding 1X10<18>cm<-3> is contained in the part near substrate surface to be distributed notably shallower than boron. For example, an element separating silicon oxide 102 is formed on a single crystal silicon substrate 101 in the peak concentration of about 1X10<15>cm<-3>. Next, the silicon oxide 102 is implanted with baron ions in the dose of about 1X10<12>cm<-2> at 60KeV to be further implanted with gallium ions larger in mass numbers than boron in the dose of about 5X10<12>cm<-2> at 80KeV. Through these procedures, the impurities are distributed as follows, i.e., the shallow peak 103 by galluim will be about 0.05mum from the substrate surface while the deep peak 104 by boron will be about 0.2mum from the same.

Inventor: HANAWA FUMIAKI
IPC: G02B6/13
Filed: 1988-01-26
Abstract: PURPOSE:To prevent a core part shape from deforming at the time of a thermal processing and to obtain a light waveguide with high accuracy and high quality by setting the relation of a softening temperature T1 of the core material of a core part formed on a substrate and a softening temperature T2 of the clad material of a clad part at T1>T2. CONSTITUTION:By a glass particulate accumulating process and a trans parentizing process using a flame hydrolysis reaction, in a quartz system light waveguide forming a core part 3a and clad parts 2 and 4 having lower refraction factor than that of the core part on a substrate 1, the relation between the softening temperature T1 of the core material and the softening material T2 of the clad material is set at T1>T2. In such a way, the temperature at the time of the thermal processing of the core part 3a, which is precision- processed into an edge shape and the clad layers 2 and 4, is sufficient at the temperature to make the clad layers 2 and 4 transparent, and the core part 3a is not made into a melting condition. There, the refraction factor of the core part 3a is made higher than that of the clad layer, and a dopant material which sets the softening temperature at T1>T2 can be doped.

Title: Method for measuring flow rate of fuel fluid in coke oven
Inventor: SAKURABA MASAAKI
IPC: G01F1/68
Filed: 1982-02-02
Abstract: PURPOSE:To measure the flow rate of fluid flowing from a duct to each heat accumulating chamber by an extremely simple method, by measuring the temperature of the fluid flowing in the duct for each heat accumulating chamber, which is communicated to a sole flue in the coke oven. CONSTITUTION:The coke oven, which performs carbonization of coal 8, comprises a carbonizing chamber 9 and a burning chamber 2, which is divided into many parts, and heats the wall of the carbonizing chamber. Fuel gas is supplied to each heat accumulating chamber 1 from a pipe 6 through the sole flue 4 and a restrictor 3, and distributed to the burning chamber 2. At this time, the temperature of the fluid distributed into each heat accumulating chamber 1 is measured by a communicating duct 11 at the upper part of the sole flue 4. Thus the distribution of the flow rate of the fluid flowing in the oven is measured. The fluid temperature has always constant range from the burning and to the time of extinguishing and the flow rate is largely related to the temperature. Therefore the flow rate distribution in the oven can be estimated extremely simply.

Title: Exhaust gas recirculation controller
Inventor: KAWAI KATSUHIKO
IPC: F02M25/06
Filed: 1986-01-28
Abstract: PURPOSE:To easily detect the anomaly of an EGR with the simple constitution by comparing the difference of the air-fuel ratio control quantities in the cases when the EGR is opening-controlled and closing-controlled with a prescribed value. CONSTITUTION:In a control circuit 8, the control quantity is calculated according to the air-fuel ratio of an engine which is detected by an O2 sensor 20, and the fuel feed quantity supplied into the engine by a fuel injection valve 4 is adjusted by said control quantity so that the air-fuel ratio of the mixed gas is maintained at the theoretical air-fuel ratio. The difference between the control quantity in the case when an EGR valve 13 is opening-controlled and the control quantity in the case when the EGR valve 13 is closing-controlled is obtained by a solenoid valve 15. Because the air quantity actually sucked into the engine is varied according to the EGR gas quantity, the air-fuel ratio of the mixed gas supplied into the engine is varied according to the presence of the EGR gas. When the difference of the control quantity accompanied with the above-described variation of the air-fuel ratio of the mixed gas becomes less than a prescribed value, an anomaly is judged, and an alarm lamp 30 is lighted up to inform a driver of the anomaly.

Title: Heat exchanger
Inventor: FUKUDA YUU
IPC: F28F19/06
Filed: 1983-02-03
Abstract: PURPOSE:To prevent color of water and towel from being changed into blue by the water from a heat exchanger, by forming a coating layer, of which main ingredient is metallic powder of which normal electrode potential to organic binder and copper contained in a heat transfer part is below 0V, on the surface of a copper heat transfer part which contacts with water, and by forming a complex of copper by letting eluted copper ion react on salt of fatty acid such as soap. CONSTITUTION:A coating layer, of which main ingredient is metallic powder of which normal electrode potential to organic binder and copper contained in a heat transfer part is below 0V, is formed on the contacting surface of a copper heat transfer part with water. Because the normal electrode potential of copper is above 0V, if the copper contained in a heat transfer part is corroded due to a pin hole and is turned into copper ion, it forms a battery with the metal contained in the coating layer of which normal electrode potential is below 0V. The copper serves as a cathode, while the metal of which normal electrode potential is below 0V serves as an anode. Then reaction on the cathode side reduces the copper ion to copper, while that on the anode side acidifies the copper ion to turn it into a metallic ion of which normal electrode potential is below 0V. Accordingly, copper ion is prevented from being eluted into water.
