Title: Local etching of copper circuit pattern on printed-circuit board
Inventor: FUKUZAWA KUNIYUKI
IPC: H05K3/22
Filed: 1987-04-27
Abstract: PURPOSE:To easily execute a local etching operation of a copper circuit pattern on a printed-circuit board by a method wherein L-ascorbic acid is added to an etching solution, ultraviolet rays are irradiated in accordance with a type of a pattern and the copper pattern in an irradiated part can be etched or L-ascorbic acid is added in order to remove the remaining copper pattern completely by irradiation with ultraviolet rays. CONSTITUTION:L-ascorbic acid functions as an oxidizing agent during a light reaction at an irradiated part, and generates a Cu<2+> ion; at a part other than the irradiated part it reduces the existing Cu<2+> ion to an etching-incompetent Cu<+> ion and prevents the part other than the irradiated part from being etched. Then, L-ascorbic acid is added to an etching solution which has been used for a thermal reaction etching operation using cupric chloride; this solution reduces the Cu<+> ion to the etching- incompetent Cu<+> ion; the thermal reaction etching operation and a light reaction etching operation can be combined easily without exchanging the etching solution. A quantity to be added of ascorbic acid may be in a range of 1/10-1/100 with reference to the copper ion. When a local etching operation is executed while the Cu<2+> ion is generated by the light reaction, it is possible to prevent the part other than the irradiated part from being etched.

Filed: 1994-05-18
Abstract: PURPOSE:To provide a camera constituted so that a focus detection area is selected by the line of the sight of a photographer when a photographing lens is manually focused. CONSTITUTION:Infrared light emitted from a line-of-sight detection device 26 is reflected on a half mirror 27 and it irradiates the eyeball 41 of the photographer. Then, the reflected image of the eyeball 41 by the infrared light is guided by the mirror 27 and formed on the inside of the detection device 26. By the detection device 26, the formed reflected image is periodically transmitted to a control circuit as image information. When a manual focus mode in which the photographing lens is manually focused is set, the position of the gazing point of the photographer is judged by the control circuit based on the transmitted image information. Besides, the focus detection area corresponding to the gazing point is selected by the control circuit. By a finder display device, the focus detecting state of the selected focus detection area is displayed as a focusing mark.

Title: Radiographic image reduction stepper
Inventor: SUZUKI YOSHIO
IPC: H01L21/027
Filed: 1987-04-30
Abstract: PURPOSE:To execute reduction stepping of a radiographic image by inclining a crystal surface at a certain angle with a crystal grating face which makes Bragg reflection and working said surface. CONSTITUTION:Monochromatic and parallel X-rays 3 or 0.62Angstrom wavelength are used and are Bragg-reflected by the (220) grating face 2 of the silicon single crystal. The angle alpha between the crystal face and the (220) grating face is set at 6.20. The reflected X-rays which are transmitted through an original image 5 and are reflected on the crystal grating face 2 are projected on a film 6. The width of the X-ray flux can be thereby reduced to M times as shown by the equation before and after the Bragg reflection. In the equation, d1 is the width of the reflected X-rays 4; d0 is the width of the incident X-ray flux 3; thetaB is the angle between the grating face 2 and the incident X-rays 3; alphais the angle at which the surface of the single crystal 1 inclines relative to the grating face 2. The use of the original image larger than the required image is thereby enabled at the time of forming the fine image and pattern. The formation of the original image is, therefore, facilitated and a positioning mechanism is simplified.
