Title: Epitaxial growth of amorphous or polycrystallin silicon on wafer
Inventor: HIRAMOTO TATSUMI
IPC: H01L21/26
Filed: 1981-09-16
Abstract: PURPOSE:To provide ease of temperature control by using as a heating source tubular lamps with all of the radiated light instantaneously variable. CONSTITUTION:A wafer 8 is inserted into a heating furnace, and when lamps 100 are lit, the alpha-Si layer on the wafer is heated to reach a substantially even temperature of 1,100-1,400 deg.C after 3-5sec. After maintaining this temperature only a lamp 100a at the end of the wafer is excessively lit and the entire region of the wafer is passed just under the lamp. Only that part of the alpha-Si layer  which is just under the lamp 100a reaches 1,410-1,480 deg.C and makes the epitaxial growth. It is preferable that the epitaxial growth be made in the vicinity of  the melting point of Si. Rising the temperature of the entire alpha-Si layer to 1,410- 1,480 deg.C simultaneously and keeping that temperature for an extended period of  time the wafer may tend to melt to cause a warp on the wafer. This partial  heating procedure, on the other hand, causes no wafer damage and warp, etc.

Title: Base air-fuel ratio controlling apparatus for electronically controlled engine
Inventor: TAKADA MAMORU
IPC: F02D41/04
Filed: 1983-08-09
Abstract: PURPOSE:To raise the accuracy in controlling the base air-fuel ratio, by using a non-linear variable resistor which makes a small change in the value of its resistance in the vicinity of the mean value of scattering of the base air-fuel ratio as a resistor for determining the base air-fuel ratio. CONSTITUTION:An ECU32 consisting of a micro-computer calculates a base injection period TP from the output signal of a distributor 30 and corrects the same on the basis of the output signals of a throttle sensor 16 and a water- temperature sensor 25. Further, the base injection period TP is corrected by detecting the ratio of control voltage Vaf to impressed voltage Vcc of a non- linear variable resistor 34 which determines the base air-fuel ratio and calculating a correction factor for the base injection period TP or corrected injection period from the above ratio of Vaf to Vcc. Since the non-linear variable resistor 34 is so designed that its control gradient is small at the 50% mean value of scattering of the base injection period corresponding to the base air-fuel ratio, it is enabled to easily control the value of resistance in the vicinity area of said mean value where the frequency of causing scattering of the base air-fuel ratio is high.
