Filed: 1991-09-20
Abstract: PURPOSE:To provide a component of high processing accuracy by dissolving and removing unnecessary parts of a single crystal silicon plate by means of alkali anisotropic, etc., high, and thereby forming a letter member. CONSTITUTION:A 400-mum thick Si wafer 21 with the crystal axis (100), whose both surfaces are subjected to mirror face polishing is heated in an oxygen atmosphere including water vapor to form over the both surfaces a heat oxided film 22. This film 22 is subjected to a patterning process into the shape of a letter member by means of photolithography and hydrofluoric acid etching. The pattern 24 and Si crystal orientation shall be is such a positional relation that the longitudinal direction of the former is in parallel or perpendicular to the (100) direction of the silicon. This is followed by anisotropic etching of silicon with alkali. This causes appearance of the (111) plane 25. Then the heat oxided film 22 as an etching mask is removed by etching with hydrofluoric acid to yield a letter member 26. Thereby a component of high processing accuracy can be obtained.

Title: Image forming device
Inventor: YAMAMOTO MASASHI
IPC: G03G15/01
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent a defective image by suppressing discharge generated at a very small gap by making the volume resistance value of an arbitrary layer other than the uppermost layer and the lowermost layer of plural surface layers smaller than that of a lower layer. SOLUTION: Three layers of a top coat layer 5a, an intermediate layer 5b and a base coat layer 5c are laminated on the surface of an aluminum pipe stock 5e at the intermediate transfer drum 5. The resistance value of the intermediate layer 5b is made 10<8> Ωcm by using material whose volume resistance value is smaller than the base coat layer 5c whereas the volume resistance value of the base coat layer 5c is 10<10> Ωcm. Thus, when the intermediate layer 5b having low resistance exists in a toner carrier, a periphery is impregnated with the electric charge of a part where a transfer roller is brought into contact with the toner carrier, so that potential is generated. Therefore, the potential of the toner carrier rises just before the point of transfer, and voltage applied to a gap is lowered, so that the discharge is suppressed.

Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To enable the irradiation of an image pickup region with uniform light at the time of macrophotographing and to facilitate the color regulation and light quantity regulation of irradiation light with simple constitution by changing the screen of a liquid crystal monitor to such a direction where the image pickup region of an image pickup means is irradiated with the exit light from a liquid crystal monitor screen. SOLUTION: When a macrophotographing mode is selected, an image data controller stops the display of the image signal captured by a CCD to the liquid crystal screen 3a and sends such image data that the liquid crystal screen 3a turns white over the entire surface of the screen to the liquid crystal screen 3a. As a result, the liquid crystal screen 3a turns white over the entire surface of the screen and emits white light. Next, a user rotates the liquid crystal monitor 3 and changes the direction of the liquid crystal screen 3a to such a direction where the image pickup region of the photographic lens 4 is irradiated with the white light emitted from the liquid crystal screen 3a.  As a result, the image pickup region may be irradiated with the light emitted from the entire screen of the liquid crystal screen 3a and the uniform illumination of the entire part of the image pickup region with prescribed illuminance is made possible.

Abstract: PURPOSE:To obtain a narrow and deep separation-groove by a method wherein, when an insulating film is to be buried in the separation groove, the central part of the groove with a high etching-speed is removed and the insulating film or a semiconductor film with a slow etching-speed is buried in a recessed part produced by the removal. CONSTITUTION:After a polysilicon film 3 and a CVD SiO2 film 4 have been deposited on an SiO2 film 2 on a p-type Si substrate, this assembly is etched selectively by reactive ion etching so that a narrow separation-groove 6 and a wide separation-groove 7 can be made. After the film 4 has been removed, a CVD SiO2 film 9 is formed on the wall of the groove via a thermal-oxidization film 8. Then, after this assembly has been etched by an HF solution, the central part of the narrow groove 6 is etched quickly so that a recessed part 10 can be made. This part is covered with polysilicon 11 and the polysilicon on the flat part is etched by reactive ion etching so that the polysilicon 11 can be buried in the recessed part 10. After the wide groove 7 has been buried by a CVD SiO2 film 12 and photoresist has been spin-coated, the films 12 and 9 are etched simultaneously so that the CVD SiO2 films 9, 12 can be buried in the grooves 6, 7. Then, the polysilicon film 3 is etched by reactive ion etching and the SiO2 film 2 is removed by the HF solution so that a gate oxide-film 15 and a polysilicon gate-electrode 16 can be formed. Through this constitution, it is possible to obtain a high integration-density LSI with a small area for the separation layer at a good yield rate.

Title: Optical information recording medium
Inventor: OKADA MITSUYA
IPC: G11B7/243
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To relax the entrance restriction of a laser beam into the inside of a groove or a rugged pit by using a high refractive index material to a guide groove part and the rugged pit part in which tracking by a converged laser beam is performed and selecting the width of the guide grove and the refractive index of the high refractive index layer to satisfy a specified inequality between them. SOLUTION: When the width of a groove becomes shorter the a half of a light wavelength, the both ends of the groove act for restricting the electric field distribution, the electric field distribution having a fixed intensity in the groove is not made to exist. By setting the refractive index of a medium on the incident side of the laser beam on the guide groove high for effectively shortening the light wavelength, by representing the width of the guide groove for tracking by w and the refractive index of the high refractive index layer 2 by na, they are set so as to satisfy a specified inequality. By forming the guide groove 3 on which a converged laser beam performs tracking as a high refractive index layer 3, the entrance restriction of a laser beam into the inside of the guide groove 3 is relaxed, the deterioration of tracking characteristic, signal recording in the groove and shortage of signal reproducing characteristic caused by forming a narrow track are resolved.
