Title: Sheet feed device and image forming device
Inventor: MIURA YUKIHIRO
IPC: G03G15/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To surely separate and feed even a sheet such as an OHP, and prevent deterioration of the separation and feed performance of the sheet such as regular paper. SOLUTION: A notch C is formed in a surface to be brought into slidable contact with a sheet S of a separation pad 44 to divide the surface into a plurality of pieces, and a clearance 60 not to interfere the deformation of the parts divided by the notch C is provided. Each divided part is deformed so as to be fallen in carrying the sheet of high adhesion, and a clearance is formed between the surface of the separation pad 44 and the sheet S to reduce the friction. In carrying the sheet of low adhesion, no clearance is formed because each divided part is not fallen, and the sufficient friction is obtained in a similar manner to the conventional one, and the sheet can surely be separated. Because each divided part of the separation pad 44 is deformed in the clearance 60 without being interfered with a pad holder 45, the function of the notch C can surely be demonstrated.

Title: Simulating method of unlimited grounded screen in rf laboratory
Inventor: BABB SAMUEL M
IPC: G01R29/10
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To enable the reduction of fluctuations in normalized site attenuation by specifying the height of an RF laboratory from the floor approximately equal to the height of the equivalent center of the radiation of a device to be tested from the floor and reducing the amount of effective absorption at areas lower than the specified height.

Therefore, a line 10 is specified approximately 1.1m high from the floor 9. Boxes 22 containing ferrite tiles are provided on a side wall 5 above the line 10, and boxes 23 not containing ferrite tiles are increased beneath the line 10 to reduce an absorptive effect. In this case, the location height of the line 10 is approximately 10-15% movable. By this, it is possible to prevent the fluctuation of normalized site attenuation in an RF laboratory.

IPC: H04N1/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide an image reader that discriminates the size of a read original with a simple configuration. SOLUTION: An MPU 82 calculates a length of an original based on setting of image quality by an image quality setting key 87d and a scanning line number of image data read by a read section 14 when the size of the read original is 'A4' or 'B5' size. When the difference between the length of the original and 257 mm of a long side length of the B5 size is less than ±5 mm, it is discriminated that the size of the read original is 'B5'. Thus, the read image data are recorded on recording paper of the same size as that of the read original. When the size of the read original is 'B5' a recording paper of 'A4' size being not selected, a recording paper of 'B5' size is surely selected.

Abstract: PURPOSE:To enhance insulating capability by a method wherein a first layer metal wiring is formed on an IC substrate, an insulating film is built by CVD and reactive ion etching to cover only the side walls of the first layer metal wiring, and an insulating film is formed by bias spattering to cover the entire surface. CONSTITUTION:A metal wiring 12 made of an Al-Si alloy is formed on an IC substrate 11 and, on the entire surface including the metal wiring 12, a PSG film 13 is formed by CVD. A process follows wherein reactive ion etching is performed for the etching of the PSG film 13, which continues against its entire surface until there is no PSG film 13 remaining on the horizontal surface of the IC substrate 11. After this process, some PSG film 13 is retained as side walls 13a on the sides of the metal wiring 12. Next, on the entire surface including the metal wiring 12 provided with the side walls 13a, an SiO2 film 14 is deposited by bias spattering. Another metal wiring is then formed on the SiO2 film 14. This method prevents the shoulders of the first metal wiring from exposure and improves the surface geometry of steps to be produced over the first metal wiring 12.
