Title: Plasma processing device
Inventor: NAKAMURA KEIJI
IPC: H01L21/31
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To ensure good plasma cleaning in a vacuum container by applying ac voltages of different phases to each of walls of a conductive plasma processing container structured with a plurality of the walls, of which surfaces are made to electrically float from a ground. SOLUTION: Walls 2, 3 of a processing container 4, exposed to plasma 6 during plasma processing and voltage applying means 5, are insulated from ground potential including a vacuum container 1 by an insulating material, and the walls 2, 3 are electrically floated. When an ac voltage applied to the walls 2, 3 is a high-frequency voltage, a self-bias voltage is generated on the walls 2, 3, ion energy colliding with the walls 2, 3 becomes high, and a film deposited on the walls 2, 3 is eliminated and cleaned. At this time, the ac voltages applied to the walls 2, 3 by the voltage applying means 5 have different phases. Thus, potentials VA, VB of the walls A, B alternately repeats the states of VA>VB and VA<VB with passage of time, and the walls A, B are alternately bombarded with ions with passage of time.

Abstract: PURPOSE:To improve the reliability and EER of a compressor by regulating the lift of an electric expansion valve according to the degree of superheat of refrigerant in case of no large fluctuation in load, and according to the operational frequency of the compressor in case of large fluctuation in load. CONSTITUTION:The suction temperature is measured by a thermo-sensor 11 and the suction pressure by a pressure sensor 12 to calculate the degree of superheat of the influent coolant. When there is no change in the number of indoor units in operation, the lift of an electric expansion valve 4 is calculated and regulated so as to attain to a specified degree of superheat of the influent coolant in order to operate an air conditioning system at a high efficiency. When the number of the indoor units in operation changes causing a large fluctuation in load, the operational frequency of a compressor 1 is measured to calculate and determine the lift of the electric expansion valve corresponding to the operational frequency, and the electric expansion valve is regulated according to the operational frequency of the compressor 1 for a specified period of time. Thereby, hunting and back flow of the liquid caused by the response characteristics of the electric expansion valve 4 are prevented, so that the reliability of the compressor and EER can be improved.

IPC: H01L21/02
Filed: 1986-04-09
Abstract: PURPOSE:To find defective bits accurately and quickly, in a semiconductor device, by providing reference marks for memory cells. CONSTITUTION:The wiring widths of power source lines 9 and 10 are determined in correspondence with circuit currents. Relatively thick wire interconnection patterns are formed at the central parts of memory parts 1 and 2. Therefore, on said power source lines 9 and 10, diamond-shaped marks 11 are formed and arranged for every cell number (4 pieces), which is determined by the mem ory capacity, countability and the like in the memory cells in the memory parts 1 and 2. Therefore, in visually observing defective parts (bits) with a microscope, the cells can be counted for every 4 cells, with the marks 11 on the power source lines 9 and 10 as references, along the Y direction of a mem ory cell array. Thus the possibility of erroneous counting is reduced. The marks 11 can be formed by the following method: the wiring is removed only at the forming parts of the marks 11 in, e.g., a wiring processes; or other manufactur ing processes such as polycrystalline silicon wiring are utilized.

Abstract: PROBLEM TO BE SOLVED: To photograph a wall face of a structure such as a coke oven or the like which is difficult to visually investigate, by arranging a reflecting mirror bending a photographic optical axis in front of a camera, moving the camera, photographing the wall face of the structure and obtaining image data. SOLUTION: A reflecting mirror MIR2 is mounted to be parallel to a z-axis in a longitudinal direction with a reflecting face directed to first-dimensional cameras LC2-LC5. The cameras LC2-LC5 are disposed at the breadthwise center of an oven in an (x) direction. A photographic optical axis MC2 of the cameras is directed to the center of a mirror face of the reflecting mirror MIR2. Accordingly, the cameras LC2-LC5 photograph images of the reflecting mirror, whereby a right vertical wall face W1 is photographed. The optical axis MC2 of the cameras LC2-LC5 can be changed to MC3 by a rotary drive motor, and therefore a left wall face W2 can be photographed via the mirror face of the reflecting mirror MIR2. Likewise, a ceiling wall face CL and a floor wall face FL of the oven can be photographed via the reflecting mirror.  Photographed image data by the cameras or image data of a display screen are stored and read out to analyze images, thereby to detect an abnormal part of the surface.

Abstract: PROBLEM TO BE SOLVED: To stably form a steam bath with no heater heated excessively, by employing such structure as a heater block directly contacts to the entire surface of inside bottom of a tab, so that bumping of an organic solvent which is reserved is hard to take place. SOLUTION: Relating to a steam bath part 1, a reservoir area 2 for an organic solvent is formed at a bottom part inside the tab.

Abstract: PURPOSE: To realize the displacement measurement without receiving the effect of the residual magnetism and with the reduced error, by setting the exciting frequency of the detecting coil of the extension error gauge to the rotational frequency of the rotor or the frequencies excepting those which are even-fold value compared with the said rotor's rotational frequency.  
     CONSTITUTION: The extension error gauge of the steam turbine is located so that space distances l+x and l-x may change between flange 11 provided to shaft 10 and detecting coils 13a and 13b each attached to casing 12. The self-inductances La and Lb of coils 13a and 13b are selected so as to be equal to each other when variation component X is O, and at the same time connected to the primary side of transformer 14. And the signal according to the change of the space distance is delivered to the secondary side of transformer 14. Here the exciting frequency is set larger than the rotational frequency of shaft 10 and also to the frequencies excepting those which are even-fold value compared with the said rotational frequency. As a result, flange 11 opposes to the coil excited by the reverse polarity and with every rotation, and is thus magnetized by the magnetism. Thus the essential error factor can be eliminated to realize the measurement with the reduced error.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To perform resource allocation for canceling the overlap of resources while suppressing the number of times of communication or network traffic by performing overlapped resource allocation change negotiation after finding candidate resources group so as to reduce the number of times of negotiation based on resource allocating states collected from respective managing agents when resources are overlapped in the resource allocation.
