Title: Depth regulator for towing machinery
Inventor: TAKEHIRA MITSUSHI
IPC: B63G8/42
Filed: 1981-10-16
Abstract: PURPOSE:To enable the holding and towing of a machinery at an optional  depth, in such a manner that the pressure of the water flow passed through a  filter from a water lead port will cause a piston to increase the referential pressure in a cylinder while the lowering of a rod will cause a transmission shaft to  rotate thus to direct the stabilizing tail upward. CONSTITUTION:The water flow 14 taken through a water leading port 2 of a towing machinery will pass through a porous filter 9 for preventing the pressure reduction due to the disturbed flow thus to apply the water pressure on a piston 6. The piston 6 will move the inner wall of the cylinder 8 downwardly. When a compressed gas having the pressure same as the water pressure at an optional depth is sealed previously through a gas sealing port 13 into a setting referential  gas pressure chamber 10, the difference from the expected depth can be decided  from the position of the piston 6. The piston rod 7 will move up and down in  accordance with the pressure difference across the cylinder then converted to the rotary motion of a transmission shaft 5 through a gear device 11. The up-down motion of the transmission shaft 5 will control the up-down motion of a stabilizing tail 4 thus to maintain the depth constant. A force amplifier 16 is provided for the purpose to prevent the force to be produced from the piston 6 from the disturbance due to the water flow of said plane 4.

Abstract: PURPOSE:To accurately develop a minute pattern with high reproducibility by keeping the temperature of the spray solution of developer, a substrate, and atmosphere inside of a sealed space. CONSTITUTION:When the developer 7 is sprayed from a nozzle 2 and the resist on the substrate 4 is developed, a temperature control system 14 works and a temperature sensor 15 detects the temperature of the atmosphere inside of a chamber 1. Based on the information of this temperature sensor 15, the intensity of a heater 10 is adjusted and the amount of exhaust air is adjusted by an automatic angle opening and closing damper 16. The temperature change of the spray solution, the substrate 4, and the atmosphere is reduced. Since developing is performed under the fixed condition of temperature a minute pattern can be accurately developed with high reproducibility.

IPC: H01L21/66
Filed: 1987-07-02
Abstract: PURPOSE:To make it possible to analyze and evaluate a time dependent phenomenon precisely by using a method for discretion of a time axis, by using potential distribution and electron concentration distribution and/or hole concentration distribution at an executing time, and computing a variable (fi) at every lattice point for discretion. CONSTITUTION:Electron concentration distribution and/or hole concentration distribution undergoes time axis discretization and can be obtained by an expression in the Figure. At this time, a variable (f) is not constant and takes a value in the range from 0 to 1. The variable is different at every analyzing place.

Therefore, the variable (f) can be adequately set. The stable computation result is obtained regardless of the magnitude from time to time. The characteristics of a semiconductor element can be evaluated highly accurately. In the expression, ek (t) is the electron or hole concentration, which is varied with the time around the arbitrary lattice point based on the time axis discretion; (fi) is a variable, which takes a value in the range from 0 to 1 and varies at evey analyzing place; (Ai) is a factor for i (t) ; and (dt) is a time section.
