Patent JP-S62128115-A (JP)
Title: Manufacture of compound semiconductor crystal
Inventor: HOSHINO MASATAKA
IPC: H01L21/205
Filed: 1985-11-28
Abstract: PURPOSE:To obtain a high-grade compound semiconductor crystal in which hetero-structure is securely formed, by making a specific weight of carrier gas introduced into a lower-stage growth chamber larger than that of the carrier gas introduced into an upper-stage one. CONSTITUTION:A GaAs substrate 12 or the like is introduced into an upper growth chamber 7. While H2 gas holding PCl3 and H2 gas serving as carrier gas are introduced through gas-induced pipes 13 and 14, N2 gas or the like, whose specific weight is larger than that of the carrier H2 gas, is introduced into a lower growth chamber 10 partitioned by a reaction tube 2 and a partitioning plate 6. Thus, the H2 gas holding PCl3 into the upper growth chamber 7 does not go round to the lower growth chamber 10 because of N2 gas in existence. Thereafter, on a stage where a crystal layer of InGaP or the like is made to grow on the substrate 12, heating of GaAs metal and IN metal serving as source materials is stopped, and introduction of the H2 gas holding PCl3 is also stopped. An InGaP crystal layer or the like is formed in a state in which composition of atoms is clearly distinguished against the GaAs substrate 12 with a hetero-interface as a boundary.

Title: Constant speed traveling controller for vehicle
Inventor: TSUYAMA TOSHIAKI
IPC: B60K31/00
Filed: 1987-10-27
Abstract: PURPOSE:To prevent the generation of speed change hunting by adjusting the throttle opening degree so that an aimed car speed is obtained by a constant speed traveling control means and setting the speed change stage according to the torque allowance which is judged from the throttle opening degree. CONSTITUTION:A constant speed traveling control means B drives a throttle valve A according to the difference between an aimed car speed set by a car speed setting means D and the actual car speed detected by a car speed detecting means C, and controls the output of an engine E so that an aimed car speed is realized. A torque allowance judging means J judges the allowance of the torque on the basis of the opening degree of the throttle valve A which is detected by a throttle opening degree detecting means H, and a speed change control means G carries out the speed change control of an automatic transmission F. When no allowance exists, for example, in ascending on a slope in the constant speed traveling, shift-up is not carried out even if the car speed converges to the aimed car speed, and the speed change stage is shift-down-set. Therefore, the convergence precision for the aimed car speed is improved, and the generation of the speed change hunting can be prevented.
