Title: Dc motor position control circuit and its method
Inventor: TAKAHASHI KUNIYUKI
IPC: G05D3/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To automate off-set adjustment by allowing a computer to control the output signal of a positional deviation correcting signal generator based on the deviation collecting information and a signal from a position sensor. SOLUTION: When a value shown by an UP/DOWN counter 11 is not zero at the time of reading, the computer 3 controls the deviation correcting signal generator 21, which outputs the deviation correcting information to an adder 12 so as to make the content of the counter 11 may become zero. When the content of the counter 11 becomes zero and the deviation becomes one pulse, a signal conversion circuit 20 reads the positional signal of the output of an encoder 15. At the time of detecting the generation of deviation as the result, the computer 3 controls the generator 21 to output the deviation correcting information from the generator 21 to add to the content of the counter 11 so as to make the signal 16 zero.

CONSTITUTION:In a fluid mixing container that mixes an influent fluid 4 and flows out the fluid, a heat pipe 7 is provided by bringing an evaporating section into contact with the outer face of upper wall and a condensing section into contact with the outer face of lower wall. The heat of high-temperature fluid contained in the upper part is absorbed in the evaporating section above the pipe 7 and discharged in the condensing section below it. Accordingly, the temperature of the fluid in the upper part is lowered and the density is increased, and the temperature in the lower part is raised and the density is decreased. Thus, natural convection current is generated, and the temperature and the density of the fluid are made uniform. Difference in temperature of the container itself in vertical direction is also eliminated.

Title: Heat treatment of iii-v compound semiconductor substrate
Inventor: KONO MICHIHISA
IPC: H01L21/324
Filed: 1988-04-12
Abstract: PURPOSE:To perform the uniform treatment of a substrate which is low in deformation of a substrate and in crystal defects, by placing a III-V compound semiconductor substrate on supports which permit a gas to pass through and performing heat treatment in such a state that the substrate is made afloat in the air by blast of inert gas. CONSTITUTION:A 2-inch GaAs substrate 5 to be annealed is placed on a support 2a having a plurality of holes in a holder 2 made of glass. The holder is divided into upper and lower chambers by the supports and the upper chamber is connected to a gas outlet 4 and the lower chamber is connected to a gas introduction port 3. A nitrogen gas is introduced from the gas introduction port and heat treatment in a short time is performed in such a state that a nitrogen gas jetted upwards from the holes of the supports sets the 2-inch GaAs substrate afloat in the air. This treatment does not bring the lower face of the III-V semiconductor substrate into contact with the supports but its treatment is performed in a state that its substrate is afloat in the air. Thus, the substrate is free from any contact part with the supports which gives rise to deformation of the substrate or any introduction of crystal defects and thus, active layers which are superior in uniformity are obtained.
