Title: Scanning optical system having arrayed light source
Inventor: KITAMURA TAKASHI
IPC: H04N1/113
Filed: 1980-10-27
Abstract: PURPOSE:To reduce the size of constitution and speed operation, and to prevent irregularity of a pitch due to the surface inclination of a deflector, by condensing luminous flux from a semiconductor laser array on the deflection surface of the deflector through a collimator lens and a cylindrical lens whose generating line is parallel to the deflection scanning surface. CONSTITUTION:A light beam emitted from a semiconductor laser array 11 is collimated through a collimator lens 13a, passed through a cylindrical lens 13b, and reflected by rotary polyhedral mirror 14 to form an image on a photosensitive drum 16 through an imaging lens 15. The pupil of the rotary polyhedral mirror side of the collimator lens 13a is set very close to a reflective surface 14b, and the cylindrical lens 13b form an image of the laser luminous flux on the reflective surface 14b linearly at right angles to the rotary axis 14a of the rotary polyhedral mirror 14. Consequently, small-sized constitution and high-speed operation are realized, and the irregularity of a pitch based upon the surface inclination of a deflector is prevented.

Title: Pattern inspecting method, device therefor and production of semiconductor wafer
Inventor: SHISHIDO CHIE
IPC: G06T7/00
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To detect a defect through simple coordinate designation when inspecting an object having plural patterns while mixing a place having two-dimensional (2D) repeatedness with a section having repeatedness only in X and Y directions. SOLUTION: A concerned point 101 is compared with comparison objects at plural positions separated just for a repetition pitch such as 102a-d, for example, and only the section having differences at all the positions is extracted as a defect candidate. Thus, even a 2D repeated section or a place having repeatedness only in the X or Y direction can be checked. The section having no repeatedness in both the X and Y directions such as an isolate point is extracted as the defect candidate but when the defect candidate commonly occurs in plural objects, it is not defined as a defect. Thus, such candidates are extruded and a true defect is discriminated.

Title: Error logging method
Inventor: YAMANA KENJI
IPC: G06F11/34
Filed: 1988-06-17
Abstract: PURPOSE:To hold new error information leaving error specification most important for the cause of an error by judging the error specification of error information stored in a logging area. CONSTITUTION:First and second logging areas are secured on a main storage (100). When the error is generated, it is judged whether or not the first logging area is filled with the error information (102). When it is not filled, the error information is stored in an information unstored part in the first logging area (104). When it is filled, it is judged whether or not the error specification represented by the oldest error in the first logging area coincides with that of the information already withdrawn in the second logging area (106). When no specification that coincides exists, the oldest information in the first logging area is withdrawn to the second logging area (108). The new error information instead of withdrawn oldest information is stored in the first logging area (110).

IPC: F16L37/10
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a quick connector capable of securing sealing ability for a long time even in the case where a rotary section is relatively rotated and capable of restraining the generation of the noise caused by vibration.

Since in this constitution, even if the pipe 3 is rotated relative to the cylindrical hole, the wearing of the O-rings is restrained, the durability can be improved.  Pressure fluctuation can be absorbed by making a pressure absorbing member made of soft material intervene on the side of the fluid contacting face of the O-rings, holding a collar made of soft material between the two O-rings, or setting a lower hardness to the O-ring positioned on the side of the fluid side out of the two O-rings than that of the other O-ring due to their elastic deformation.
