Title: Picture reader and its method
Inventor: KATAOKA JUNNOSUKE
IPC: H04N1/401
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To read a picture free from blur without adjusting a distance between the surfaces of a contact sensor and an original platen by each solid body by deciding edge emphasizing gain and a filtering coefficient based on a modulation transfer function(MTF) obtained by calculating the maximum and minimum values of picture data read from a stripe belt. SOLUTION: Before reading an original, a shading correction circuit 14 generates a shading correcting value, a line imaging sensor 10 reads a stripe belt and an MTF value arithmetic circuit 16 generates an MTF value from maximum and minimum values in one line of picture data to store in a register 18. At the time of reading the original, an edge emphasizing & filtering circuit 17 sets high edge emphasizing gain and a low filtering coefficient in the case of a low MTF value and sets low edge emphasizing gain and a high filtering coefficient in the case of a low MTF value. Thereby, the blur and roughness of the picture is prevented.

IPC: H01L29/417
Filed: 1988-06-15
Abstract: PURPOSE:To obtain a manufacturing method of MESFETs in such a way that their characteristics do not vary after bringing them to perfection by forming low resistance materials on a thermal resisting gate electrode in self-alignment manner. CONSTITUTION:When FETs are manufactured, low resistance materials 5 are formed on a thread resisting gate electrode 3 by means of self-alignment. For example, a relatively low concentrated n-type GaAs single crystal layer 2 is formed on a semi-insulating GaAs substrate 1. Then, after performing the surface treatment of an n-type layer 2, thermal resisting gate electrode materials of WSix and the like are formed over the whole face of the n-type layer and then, a gate electrode pattern 3 is formed with a dry etching process. Subsequently, etchback is performed with the dry etching process after coating the whole face of the layer 2 with a resist 4 to treat it by lift-off at a part of a thermal resisting material gate 3. Further, dry etching is carried out on condition that only thermal resisting materials are etched selectively and etching of the thermal resisting materials 3 is performed halfway. The low resistance materials 5 consisting of Ti-Au and the like are deposited over the whole face and lift-off treatment is performed.

Title: Two-component developer
Inventor: ASANUMA MASAHITO
IPC: G03G9/097
Filed: 1985-07-05
Abstract: PURPOSE:To prevent the generation of the black stripes arising from talc and the appearance of a density difference by adding a slight amt. of a material to be electrostatically charged by friction to the polarity reverse from the electrostatic chargeableness of a toner into a developer consisting of the toner and developer. CONSTITUTION:The toner 2 is electrostatically charged positive by friction with the developer not shown. The toner 2 sticks to an image part A at 300V potential difference because of the potential distribution shown in the figure. Since a non-image part B has the potential large than bias voltage -200V, the toner 2 does not stick thereto. The developer contains the material 3 to be frictionally and electrostatically charged to the polarity reverse from the charge polarity of the toner in addition to the above-mentioned toner 2 and the developer. The material 3 frictionally charged to the reverse polarity sticks in the direction reverse from the toner, i.e., to the non-image part B by having 150V potential difference. The talc sticks onto the material 3 even if the talc sticks to the non-image part by such effect of the developer; therefore, the talc is easily removed by a cleaning blade in a stage for removing the remaining toner.

Abstract: PURPOSE:To obtain a tracking error signal via a simplified photodetecting part forming this part with three photodetecting elements set in parallel to each other and separated from each other via two pieces of parallel separating parts extending in the specific direction. CONSTITUTION:A photodetecting part is formed with three photodetecting elements D1-D3 which are set in parallel to each other and separated from each other via two pieces of parallel separating parts E1 and E2 extending in the specific direction. This specific direction is limited within a 0-90 deg. range to the moving direction of a diffraction pattern caused by the recording tracks and emerging in a beam spot formed by the light beam made incident on a set 51 of photodetecting elements. Then a tracking error signal is produced based on the detection output obtained from the center photodetecting element D2 of said set 51 as well as the sum of the detection outputs obtained from two photodetecting elements D1 and D3 that hold the element D2. Thus it is possible to obtain the tracking error signal via a simplified photodetecting part with no strict control required.
