Title: Dry etching device
Inventor: MATSUO TADASHI
IPC: H01L21/3065
Filed: 1987-06-26
Abstract: PURPOSE:To improve an etching shape and the etching uniformity and to enhance the universality of an ECR dry etching device by a method wherein a magnetic coil surrounding a plasma generation chamber is divided and excitation currents which are mutually independent are made to flow. CONSTITUTION:Excitation currents are designated as i8-i10 in divided magnetic coils 8-10; if the electric currents specified as i8<i9<i10 flow, a strength distribution 11 of a magnetic field approaches a line parallel to an axis; a region 12 which satisfied a condition for electron cyclotron resonance (ECR) by microwaves is extended to a wider range of a plasma generation chamber; an electric discharge at a low gas pressure becomes possible. If the excitation currents i8-i10 are controlled at appropriate values, it is possible to form a ring-shaped high ion density region of an optimum size corresponding to a change in a size of a wafer and a change in an etching condition. By this setup, an ECR dry etching device can be applied to an etching operation requiring the low shock energy in order to suppress the damage on the surface.

Title: Stage controller, stage device and exposing device
Inventor: YO AKIMINE
IPC: G03F7/20
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a stage controller capable of performing highly accurate control. SOLUTION: A target position generator 40 generates a reference signal RS1, for instance, for a wafer stage unit WS. A controller 44 controls the movement of a stage in accordance with a control signal CS1. A laser interference device 32 detects the position of the stage, and a feedback signal FS1 is generated. An operating part 43 outputs a deviation signal corresponding to the difference between the reference signal RS1 and the feedback signal FS1. A compensating circuit 49(#1) eliminates a specific frequency band component included in the deviation signal ES1 and outputs the control signal CS1.

Title: Fuel injection quantity control device of multi-cylinder internal-combustion engine
Inventor: WATANABE HARUO
IPC: F02D41/10
Filed: 1982-09-16
Abstract: PURPOSE:To suppress excessive fuel feed in several combustion strokes following the combustion stroke just after acceleration by sensing the total amount of asynchronous injection from a synchronous injection till another and by making a reducing correction of the subsequent synchronous injection in accordance with the amount sensed. CONSTITUTION:The J1 and J2 in a synchronous injection and X1 and -X4 in asynchronous injection have influence upon Cylinder #3. Cylinder #3 which makes combustion stroke just after acceleration is fed with a fuel amount Q near the requisite value Qf by the synchronous injection regardless of delay in response of an air flow meter. As this synchronous injection has influence also upon Cylinders #4, #2 and #1 to make the combustion stroke, which follows the combustion stroke just after acceleration and in which the delay in response of air flow meter is being eliminated, so that total amount in asynchronous injection is sensed, and if the sensed value is above the specified value the width of synchronous injection J3 just after acceleration shall be suppressed from A1 to A1'. Thereby overrich mixture in the cylinders to make combustion strokes following the one just after acceleration can be suppressed. This software is entered in the ROM in the form of a program.

Title: Cooling method for reduced pressure molding mold
Inventor: HASHIDA RIYOUZOU
IPC: B22C9/02
Filed: 1980-11-17
Abstract: PURPOSE:To facilitate control of texture and material strength of a casting and increase rotation of molding flask by increasing cooling speed of a casting poured in a reduced pressure molding mold by flowing of refrigerant to a pipe burried in the mold. CONSTITUTION:A suction air chamber 2 of a metal frame 1 for reduced pressure molding is connected to a vacuum pipe through suction air outlet 3. An undulatory cooling pipe 4 in the frame 1 is connected by reinforcing members 5 and  the end parts 6 are supported by a stopper 7 and at joints 10 which are at refrigerant inlet 8 and outlet 9. The frame 1 is set on a pattern when molding  and in this state the pipe 4 is kept horizontal. After molding, the lower die is  reversed. At this point of time, however, the pipe 4 is completely burried and fixed in molding sand. During the process of pouring molten metal in the mold  and cooling the casting 12, a cooling medium such as water, air etc. is let flow.  Spaces between sand particles are negative pressure during continuation of suction until completion of solidification and cooling effect is small. After stopping  suction, however, the effect is large enough to compensate for delay in time.
