摘要： PROBLEM TO BE SOLVED: To eliminate some problems that a controlling operation most suitable for a state of each of clean booths could not be carried out in the prior art for adjustment of temperature and humidity of an entire room and further remove a disadvantage that an air flow in the booth is inclined and the booth is easily influenced with dusts generated from a worker. SOLUTION: A unit capable of adjusting both temperature and humidity is installed in the prior art clean booth. The most suitable temperature and humidity control in the booth can be carried out. An air flow regulating plate is fixed to the central part of an air-blowing segment in the booth. A working area is arranged just below it. Workers are placed at both sides of the working area and then the cleanest air not influenced by dusts generated from the workers can be supplied to a working surface.

摘要： PROBLEM TO BE SOLVED: To eliminate some disadvantages that a large-sized line configuration of the prior art transferring of a large amount of lots hardly accommodates for products showing severe variation, provides a non-efficient operation taking a long stopped time of line accompanied by useless investment or modification, and further to remove a substantial problem that a complete distribution of clean concept may produce a tremendous operating expenditure for cleaning operation or a clean packaging of parts or an opening of the packaged product. SOLUTION: A line is made as a minimum unit, installed in a cell booth. The booth is of a structure facilitating its adding or removal. Each of the cell booths is connected to each other by a clean tunnel structure of panel structure that can be easily increased or decreased, thereby it becomes possible to attain a requisite and minimum clean state and the most-suitable line structure.

摘要： PROBLEM TO BE SOLVED: To support the restoration of failure by shortening a restoring time and finding a job being the cause of the failure at the time of the generation of the failure in a computer system. SOLUTION: At the time of starting or ending the execution of a job in job execution control 102, or at the time of an input and output information capture processing 103 provided in the close processing of a file input and output processing, an event generation processing 107 is called, a job start event, job end event, and close event are generated, and an execution history 163 constituted of an end code, starting time, ending time, executing time, and input and output history or the like is prepared for each job based on those events by a monitor processing 151. Then, at the time of the generation of failure, a failure supporting processing 152 is activated, the execution history 163 is compared with a standard history 164 based on normal execution, the abnormality of the number of times of input and output, executing time, and end code is checked, an abnormality flag is stored in the execution history, and a job in which the abnormality is generated is defined as a job being the cause of the failure. Then, after the restoration and re-assignment of a file, a re-executing instruction is issued.

摘要： PROBLEM TO BE SOLVED: To change en bloc a condition of every communication in three operations and also to know a set content of a present communication condition in a single procedure by placing an icon on an off-screen to start a setting function of a communication condition against the communication abnormality, etc. SOLUTION: When a communication condition icon placed on an off-screen is selected through every communication screen, an off-screen function control part 12 starts a communication condition setting function. At the same time, a communication condition display control part 13 sets the information stored in the communication condition data 32 to the communication condition screen data 33 and shows a communication condition setting screen. When a communication condition item is changed on the communication condition setting screen, the data 33 are accordingly changed. Then an execution icon or a cancel icon is selected on a communication condition screen. When the execution icon is selected, a communication condition change control part 14 sets the information on the data 33 to the data 32 and closes the communication condition setting screen to reset the original communication screen.

摘要： PURPOSE: To obtain a disk device capable of opening the disk without deteriorating the performance of main components of the disk device at the time when the disk device is disassembled. CONSTITUTION: In a head disk assembly of this disk device, a ring 109 for shrinkage fit is subjected to shrinkage fit to a hub 104 at a specified position to hold the clamping force given to the disks 106a, 106b, 106c, 106d, 106e by a clamp 108. An inner wall surface 109a is formed on the upper surface of this ring 109 for shrinkage fit along the outer periphery. The ring 109 is removed from the hub 104 in such a manner that a load in the direction pushing and expanding the ring 109 is applied to the inner wall surface 109a to generate suitable plastic deformation on the ring 109.

摘要： PURPOSE:To easily and accurately judge the region on which inpattern proximity effect is generated in a focussed beam lithography and a proximity effect correction treatment is conducted on the above-mentioned region in a simple manner. CONSTITUTION:A lithography pattern is divided into straight lines L12, L13... which are extending in the scanning direction (x-direction) of electron beam, and rectangular regions 10A, 10B,... using straight lines L21, L22... which orthogonally intersecting with the above-mentioned straight lines. Also, the line segment X, which comes in contact with the profile L0 of the pattern and extending in the x-direction, is worked out and the line segment Y, which comes in contact with the profile L0 and orthogonally intersecting with the scanning direction, is worked out. The shortest line segments Xa, Xb, Xc..., passing regions 10A, 10B..., are worked out for each region, and the shortest line segments Ya, Yb, Yc... of the line segment Y pssing the same regions, are worked out. In each region, the shorter one of the line segment X and Y is set on the parameter W which shows the width of region. This value W is compared with the base values W1 and W2, and the intensity I1 to I3 of the beam with which the region is irradiated are determined. They are conducted by one graphic operation treatment.

摘要： PURPOSE:To accurately conduct a pattern arithmetic operation for every hierarchy by a method wherein a pattern arithmetic operation is conducted on the pattern data which is recomposed by developing a part of the pattern data to be determined based on the pattern arithmetic operation influencing distance and the unnecessary part, which is determined based on the above-mentioned pattern arithmetic operation influencing distance, is removed. CONSTITUTION:A reference frame 13 is provided on the inside part in the distance (d) from the inner frame 12, and a reference frame 14 is provided on the inside part in the distance D from the inner frame 12. Among the patterns on a block B, the pattern outside of the reference frame 14 is developed on a block A and a block A1 is formed. The prescribed pattern arithmetic operation is conducted on the block A1 and the block B independently. In the pattern data A2, as the pattern inside of the reference frame 13 belongs to the block B intrinsically, it is eliminated and a treatment result data A2 is obtained. Also, as the pattern outside of the reference frame 13 is reflected on the treatment result data A2, it is eliminated. As a result, the treatment can be obtained.
