IPC: H01L21/027
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To efficiently perform exposure by using a small number of reticle patterns. SOLUTION: In consideration of the rotational symmetry of a rotary optical element, a substrate 3 is divided radially into three parts from its center and also divided into 4, 12, and 18 respectively in the circumferential direction to form exposure areas 21a, 21b, and 21c. At the outer peripheral edge part of the substrate W, alignment marks M0, M2, and M3 corresponding to the angles of rotation of the substrate W and used for alignment are formed; and exposure is repeated at specific exposure positions while the substrate W is rotated to pattern the substrate with a minimum number of reticles.

Title: Surface defect detecting method
Inventor: GOTOU YUKIHIRO
IPC: G01N21/956
Filed: 1982-10-27
Abstract: PURPOSE:To detect a surface defect at high speed and with high accuracy, by dark-field illuminating a surface on which a pattern having directional properties has been formed, with rays different in wavelength which are respectively applied in a direction parallel to the pattern direction and in a direction intersecting the same. CONSTITUTION:When a patterned surface is subjected to dark-field illumination with the light radiated from a light source, the red light Lr passing through a red-light transmissible filter in a slit 12r becomes parallel rays having no Y-axis component, which radiate the patterned surface from a diagonal upper side along an X-direction line 21. Similarly, the blue light Lb radiates the patterned surface from a diagonal upper side along a Y-direction line 22. A color ITV picks up the image of the patterned surface through a microscope and separately outputs red and blue video signals to respective binary-coding circuits. In an AND circuits, each set of corresponding picture elements is subjected to anding operation, therefore, the output takes ''1'' only when signals representing the corresponding picture elements both take ''1''. The images of the lines 21, 22 disappear and only the image corresponding to a defect appears in a judgement circuit.

Title: Imaging apparatus
Inventor: TANDA HISAYA
IPC: B41J11/48
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus in which a recording medium or a sheet feed roller is not subjected to deformation even if the imaging apparatus is not used for a long term and left as it is. SOLUTION: When a roll sheet 14a is under feed, a pulley 174 is separated from a leaf spring 178 and a sheet feed roller 76 comes into press contact with the surface of the roll sheet 14a. Upon ending sheet feed, an electromagnetic clutch 162 is disconnected and an electromagnetic clutch 164 is connected. A drive motor 156 is driven under that state to turn a pulley 174 by 90 deg. in the direction of arrow B. Consequently, the long diametral part of the pulley 174 pushes down the leaf spring 178 and a waiting roller 180 moves downward to touch the outer circumferential surface of the roll sheet 14a. An upper sheet feed plate 152 thereby floats correspondingly and the sheet feed roller 76 is separated from the outer circumferential surface of the roll sheet 14a.

Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce labor cost and to solve a quality control problem by delivering asphalt by screws in steel pipes, and paving in specific width, combining compaction by an iron. SOLUTION: In paving work, asphalt is delivered by the rotation of screws provided in steel pipes in an automatic asphalt paving machine with a paving width of 600 mm-1200 mm to pave combining compaction using an iron. Because of simple structure of providing the screws in the steel pipes to deliver asphalt, the machine can be operated even by two or three common workers at the minimum. The iron is formed in bow shape to facilitate the spread of asphalt. Manual construction work is thereby replaced with mechanical construction work to reduce labor cost and the like by a large margin and to solve a quality control problem such as a rough finish of a pavement caused by the temperature drop or the like of asphalt during manual construction work.

Title: Pressure sensor
Inventor: YANAGI MASAHIRO
IPC: G01L9/04
Filed: 1994-08-10
Abstract: PURPOSE:To obtain an inexpensive, highly accurate, and stable pressure sensor having an excellent environmental resistance by providing a metallic substrate carrying a metallic thin-film resistor on its surface facing the pressure introducing hole of a pressure-resistant metallic container. CONSTITUTION:A pressure-resistant metallic container 7 having a pressure introducing hole 8 which is connected to an object to be detected and has a T-shape is fixed by projection welding to the outer periphery of a metallic substrate (made of, for example, high yield strength steel) on which an insulating layer (SiO2) 2, metallic thin-film resistor (made of, for example, nichrome) 3, and protective layer 4 are successively formed. When the pressure of the object becomes higher, the substrate 1 connected to the hole 8 is deformed and the outer peripheral section of the resistor 3 contracts due to a bending stress, whereas the inner peripheral section of the resistor 3 reversibly extends. As a result, the resistance value of the outer peripheral section of the resistor 3 becomes higher than that of the inner peripheral section. Therefore, the pressure of the object to be detected is detected by obtaining the output corresponding to the changing rate of the resistance value by applying a bias voltage.

It is also judged whether or not a condition for rejecting manually directed gear shifting, has been established. Namely, when oil temperature is low, and oil viscosity is high, since shift quality is possibly high, it is judged that a condition of rejection is thereby established, and the aforesaid control device is brought into a nonexecuting condition for gear shifting. And when a specified condition is satisfied while a change-over directing condition is being continued, the change-over of each step of gear shifting and each range for gear shifting as directed is thereby executed based on manual operations.
