Title: Ecr plasma processor
Inventor: SATO JUNICHI
IPC: C23F4/00
Filed: 1991-10-25
Abstract: PURPOSE:To reduce the particles adhering to the surface of a semiconductor wafer by providing an adhesion preventive member, whose surface has many projections, at least in the vicinity of the part where plasma chemical reaction occurs and which is on the surface of the substrate inside an ECR plasma reaction chamber. CONSTITUTION:The adhesion preventive member 14, which surrounds the space where ECR plasma chemical reaction occurs above the semiconductor wafer 8 inside an ECR plasma reaction chamber 6, is provided on the inner surface, and has a number of, for example, integral hexagonal honeycombed-pattern projections 15. The particles tending to adhere to the place excluding the surface of the wafer 8 in the plasma processing mostly adhere to the inner surface of the adhesion preventive part 14. The particles hardly separate because of the projections. Since the adhesion preventive part 14 is replaceable, when the adhering reaction products 12 become thick, it can be replaced.

Title: Burner
Inventor: ARAI YASUHIRO
IPC: F23C6/04
Filed: 1986-12-25
Abstract: PURPOSE:To effectively decrease nitrogen oxides, and to prevent intermediate combustion products such as carbon monoxide from being discharged to the outside, by providing an exhaust gas introducing pipe having a catalytic function to reduce combustion exhaust gas, running from the neighborhood of the forming position of a flame in a combustion chamber to the neighborhood of the inlet of a burner body. CONSTITUTION:The inlet part 18 of an exhaust gas introducing pipe 17 for combustion exhaust gas is inserted into a combustion chamber 9 from a back space 16 to be disposed in the neighborhood of the forming position of a flame 8. The outlet part 19 of an exhaust gas introducing pipe 17 for combustion exhaust gas is inserted into a burner throat 2 from the bottom of a back space 16. The exhaust gas introducing pipe 17 has a double-wall structure, of which inner pipe 20 is made of a material having a catalytic function to reduce gas, stainless steel for example. It is not necessary to use an exhaust gas recycling blower because fuel exhaust gas flowing into the exhaust gas introducing pipe 17 is fully led into the burner throat 2 only by the suction effect of reduced pressure by injecting force of fuel. Low NOx combustion can be caused by the decrease of concentration of O2 in combustion air in the combustion chamber 9 and by lowering of the temperature in a flame because part of combustion exhaust gas is returned to the burner throat 2.

Said gear 44 is integrally fixed to a shaft 28a having a lower delivery roller 28 coaxially fixed thereto. When the pulse motor M1 is reversed and the gear 44 starts rotary driving in the counterclockwise direction as shown by an arrow B, the base plate 42 rotates around the shaft 42a in the counterclockwise direction and the lower delivery roller 8 is brought into close contact with an upper delivery roller 29 to perform delivery operation. When the gear 38 rotates in the direction shown by an arrow B, the rotation thereof is not transmitted to the platen roller 22 by the one-way clutch CL.

For the picture-element data, grids are formed at prescribed intervals of picture elements; a window (W) is formed by using a black-level grid as a reference. When a black grid level does not exist on a boundary of the W, the number of black-level grids inside the W is within a prescribed range and all interval between black-level picture elements is within a prescribed range, it is judged that a position and a size of a component is within a permissible range. A coordinate position of the center of gravity is computed, and a gripping position where the component is to be sucked is computed. Then, a next component is searched. When the component cannot be found, an instruction is sent to a component feed apparatus 2 and the component is fed.

On the other hand, the vertical displacement of each suspension mechanism is obtained from the detected signal of a vehicle height sensor 28 which passes a low frequency filter 51, and the energy which can be absorbed by each suspension mechanism is obtained from the vertical displacement and the supporting load of each suspension mechanism. The speed limit of each suspension mechanism corresponding to the energy is obtained, and the bump-stop force of each suspension mechanism 19 is obtained from the speed limit so that the position control force may not exceed the bump-stop force.

Title: Disk device
Inventor: HASEGAWA SHINICHI
IPC: G11B11/10
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To improve a static characteristic after a jump operation by driving and controlling a moving means so that the moving direction of a beam spot is reversed when it is confirmed that the signal level of a tracking error signal reaches within a prescribed threshold. SOLUTION: A DSP 21 allows an actuator for tracking to move an objective lens so that the beam spot of a laser light beam L1 moves toward a target track by transmitting a control signal S5 to a tracking driving circuit 9. Next, the DSP 21 judges whether after the absolute value of the signal level of the tracking error signal to be supplied from an optical block 8 exceeds a threshold level, the absolute level reaches within the threshold or not. Thereafter, when the DSP 21 obtains an affirmative result, the DSP 21 reverses the sign of the control signal S5 to transmit it to the circuit 9. After this, the DSP weakens the driving output of the actuator for tracking gradually and completes the processing procedure of this operation mode when the affirmative result is obtained.
