Title: Oil pressure valve device
Inventor: KATO HIDEYO
IPC: F15B11/05
Filed: 1994-11-10
Abstract: PURPOSE: To provide an oil pressure valve device capable of miniaturizing the device and reducing a manufacturing cost by realizing the commonness of the structure and arrangement of constant differential pressure type and variable differential pressure type pressure compensation valves. CONSTITUTION: When pressure, received by a first pressure receiving part 61b in an upward direction from an inflow port 10, is weaker than the sum of the highest load pressure received by a second pressure receiving part 61c in a downward direction and the spring force of a spring 32s, a pilot valve 61 is pressed downward to shut off a back pressure chamber 54 from a second passage 64. Pressure oil in the inflow port 10 is led in the back pressure chamber 54 via a first passage 62 to seat a main valve 60 to shut off the inflow port 10 from an outflow port 11.  While when pressure, received by the first pressure receiving part 61b in an upward direction, is increased, the pilot valve 61 is moved upward to allow the second passage 65 to communicate with the back pressure chamber 54 to flow out pressure oil in the back pressure chamber 54 into the outflow port 11, but at that time, the inner pressure of the back pressure chamber 54 is lowered by pressure drop through an orifice 63 to move the main valve 60 upward to directly allow the inflow port 10 to communicate with the outflow port 11.

Filed: 1991-09-27
Abstract: PURPOSE:To precisely assume an eroded line in a furnace bottom by inputting the actual thermal conductivity of the eroded brick in the furnace bottom and the temp. of a brick eroded surface found from the dismantle investigation result. CONSTITUTION:In the dismantle inverstigation result, the insertion of an pig iron into a joint part is confirmed to an isothermal line at 1150 deg.C solidifying the pig iron. These exisit a little degradation in the brick in a range of no existence of the insertion and the thermal conductivity of this brick is equal to that of the sound brick. In a range to the eroded surface of the brick at >=1150 deg.C, the thermal conductivity of the brick reaches to about four times that of the sound brick because of the insertion and penetration of the molten iron. In the actual measured value of the brick temp. in the furnace bottom during operation, the max. temp. is selected, and at the time of assuming the eroded line in the furnace bottom so as to make it equal to this temp., it coincides to the isothermal line of 1350 deg.C. Therefore, it is desirable that the eroded surface temp. of the brick in the furnace bottom is made to between the solidified temp. of 1150 deg.C and iron tapping temp. of 1500 deg.C and the thermal conductivity is made to about four times of the sound brick. In this condition, the furnace eroded line obtd. on the basis of the actual measured temp. value at plural positions in the furnace bottom becomes highly accurate.

CONSTITUTION:A spindle head 1 to be placed thereon with a substrate, etc., a piping 4 for feeding of gaseous N2, etc. into the chamber 2 for coating the resist soln. on the substrate and a piping 3 for controlling the temp. in the chamber are provided to said chamber so that the chamber can be hermetically sealed in the production of a semiconductor device, etc. The material to be coated such as the substrate is placed on the head 1 and the inside of the chamber is substd. with N2. The resist coating liquid is coated on the substrate while the inside of the chamber is maintained at a desired temp. and while the spindle head 1 is rotated. The evaporation rate of the solvent is adjusted to a suitable rate to prevent the formation of the nonuniform film as a result of the stringing of the coating liquid to form here and there projections on the resist film surface or the incorporation of the moisture in the atmosphere into the resist film in the stage of dropping the coating liquid. The satisfactory and uniform film is thus formed even by using the highly volatile solvent.
