Title: Torque control device for hydraulic pump for hydraulic construction machine
Inventor: NAKAMURA KAZUNORI
IPC: F04B49/06
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce a drop of the number of rotations of a prime mover under a high load and to execute processing as fast as possible with limited processing performance of a controller, even if an output of the prime mover is lowered, in a torque control device of a hydraulic pump for a hydraulic construction machine. SOLUTION: When an output of an engine is dropped, caused by an environmental change, signals from sensors 75 to 82 are received by correction gain calculation portions 70m to 70u to calculate a torque correction value ΔTFL in the correction gain calculation portions 70m to 70u and a correction value calculation portion 70v. In a speed sensing torque deviation correction portion 70i, the torque correction value ΔTFL is reduced from a deviation ΔTI to obtain a value ΔTNL. The value ΔTNL is added to pump base toque TR0 to obtain absorption torque TR1. Signals are outputted to a solenoid control valve 32, and the maximum absorption torque of hydraulic pumps 1, 2 is controlled by controlling a servo valve 22 for all horse power control.  The signals from the sensors 75 to 82 are taken in a memory at a predetermined time interval defined by input timing control portions 96a to 96h.

Title: Method of analyzing fluid behavior in well of geothermal fluid containing carbon dioxide
Inventor: TAKAHASHI MASAHIRO
IPC: E21B43/00
Filed: 1987-10-05
Abstract: PURPOSE: To prevent scaling by calculating the conditions of a pit mouth through the repetition of a process for determining depth while regarding the partial pressures of gas and water at the start of flashing as total pressure, that for determining total pressure from the mole number of gas in a liquid phase, and that for determining depth at a certain temperature from each loss. CONSTITUTION: The total flow of eruptive gas and the mole of carbon dioxide are determined through analysis of fluid behavior in an in-reservoir-layer single- liquid-phase area 1 near a well and total pressure is determined from the partial pressures of carbon dioxide and water at the start of flashing on the basis of temperature within a reservoir layer through analysis of fluid behavior in the single-liquid-phase area 2 in the well, whereby the depth to which pressure drops is determined from both positional and frictional losses. The mole ratio of carbon dioxide and hot water and the mole ratio of carbon dioxide and steam in a gaseous phase are determined through analysis of fluid behavior in an in-well gas-liquid double-phase area 3 after flashing and total pressure is determined from their partial pressures. Therefore, the behavior of liquid can be known at the desired time.

CONSTITUTION:A right side unrolled part 1b to be formed as the thin-walled part is rolled when the roll 4 rolls from the left to the right. The thick-walled part and the step part 1a thereof are in contact with the guide 5 and therefore the movement toward the left is prevented. The left unrolled part to be formed as the thin-walled part is similarly rolled when the roll 4 rolls from the right to the left. The force moving toward the right acts on the thick-walled part and the step part 1a thereof in this stage but the force is blocked by the guide 5. The thick-walled part and the step part 1a thereof are therefore prevented from moving to the right and left even is the roll 4 rolls. The galling of the step part by the roll 4 and the bending thereof in the longitudinal direction are thus obviated and the broad deformed bar of a long size having excellent dimensional accuracy is efficiently produced.

Title: Manufacture of semiconductor device
Inventor: ARIMA YASUO
IPC: H01L21/3213
Filed: 1990-09-19
Abstract: PURPOSE:To enable high-accuracy formation of well-shaped contact holes in a resist film by a method wherein the surface of a wiring layer is equipped with a transparent insulating film coated with a film made of a material blackening by exposure. CONSTITUTION:A semiconductor substrate 1 is surfaced with a wiring layer 2, which is then overspread with a PSG film 3, and a film made of a material blackening by exposure, e.g. a silver chloride film 4 is formed over the whole surface. A resist film 5 is spread over the surface and loaded with a mask 6 which has a transparent part 6a at a part for light transmission and a light- shield film 6b at a part for light shield, and the resist film 5 is exposed to light. Exposure rays are transmitted through the transparent part 6a of the mask 6 by exposure and then through the resist film 5 to reach the silver chloride film 4, where photosensitization and blackening of the silver chloride film 4 causes exposure rays to be absorbed by this film 4 and prevents them from reaching its underlying wiring layer 2. Therefore, when the resist film 5 is exposed to light with high accuracy only by exposure rays from above to remove the mask 6 and to develop the resist film 5, it is possible to form well- shaped contact holes 5a.
