IPC: H01L27/01
Filed: 1985-01-11
Abstract: PURPOSE:To omit processes of trial trimming and to enhance trimming accuracy, by forming the masks of trimming patterns beforehand at a part of many semiconductor chips, which are formed on a semiconductor wafer. CONSTITUTION:The mask of trimming patterns is formed on three central lines of temperature sensing IC lines S1-S3 in a semiconductor wafer under the different conditions. The mask of the same trimming pattern as that of the line S2 is formed on a temperature sensing IC chip line K, which crosses the lines S1-S3 at a right angle. The lines S1-S3 are cut out of the wafer 2, and a packages are formed. The distributions of the output currents of said three lines are obtained. The offset correcting value, at which the error becomes 0.00 deg.C, is estimated. The output current of the chip in the line K remaining on the wafer 2 is corrected by the offset correcting value, and the intended output current is obtained. With said intended output current as an objective, the main trimming of the remaining chip is carried out.

Abstract: PURPOSE:To maintain pressure in the hydraulic cylinder at predetermined pressure, and to maintain the state of stoppage of the hydraulic cylinder positively by expanding and contracting the hydraulic cylinder and supplying an oil chamber at the load maintaining side of the hydraulic cylinder with pressure oil from an auxiliary circuit. CONSTITUTION:When boom 6 is stopped for a prolonged term, the temperature of pressure oil drops gradually, pressure oil in the oil chamber 53 at the push side is shrunk gradually, and the boom 6 tends to fall. When a changeover  switch is turned ON in such a case, a valve 75 is changed over, and pressure oil  from an accumulator 74 is introduced in the direction of the arrow (f), and flows  into the oil chamber 53 at the push side of an expansion cylinder 5 through a second electromagnetic changeover valve 75, a variable reducing valve 76, a  check valve 78 and a counterbalance valve 4. Accordingly, pressure oil corresponding to the quantity of shrinkage and oil leakage is supplied into the oil  chamber 53 at the push side, and the shrinkage of the expansion cylinder 5 and  the boom 6 is prevented.

Inventor: SAWA MASAAKI
IPC: C23C4/18
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of sprayed coating film on a base material and to increase its durability by forming nonmagnetic sprayed coating on the surface of a magnetic cylindrical base material, applying high-frequency from the surface of this sprayed coating to heat the surface layer part of the base material and diffusing the surface layer part of the base material into the sprayed coating film.

After that, while a high-frequency induction heating work coil 3 is moved in the longitudinal direction of the base material 1, high-frequency is applied to the surface of the sprayed coating film 2, and the surface layer part of the base material 1 is heated. Thus, the base material 1 thermally expands to apply face pressure to the sprayed coating film 2, the adhesion of the sprayed coating to the base material 1 increases, and the metallic atoms of the base material diffuse into the sprayed coating film 2 to remarkably improve the durability of the sprayed coating 2.
