Title: Coordinate input device
Inventor: ASHIDA AKIHIRO
IPC: G06F3/03
Filed: 1985-05-14
Abstract: PURPOSE:To make the construction simple and to make the titled device low in price by using resiliency to function between two magnetic thin plates to separate two resistance sheets from each other except the time of the coordinate input. CONSTITUTION:For two resistance sheets 2 and 3, the desired interval is kept even at the vicinity of the central part by the resiliency of magnetic thin plates 5 and 6. When the force is applied to the input surface, at the place, conduction is obtained between resistance sheets 5 and 6 by the deformation of the resistance sheet 2 and the magnetic thin plate 5 and the input position can be detected. Consequently, the correct pressuring pattern can be inputted.

IPC: G03B13/36
Filed: 1982-06-14
Abstract: PURPOSE:To improve the accuracy of focus detection and to control exactly automatic focusing, by selecting the photoelectric conversion surfaces of a focusing detection element and changing the range where the focusing detection is processed thereby varying the area for detecting focusing. CONSTITUTION:When a zoom ring Z is turned in such a way that a zoom state comes to a telephoto side, the information (for example, the focal length of a zoom lens) of zoom information Z is varied. The information is detected with a control part I for processing focus detection which controls the range Q where the focusing detection is processed and which consists of the group of photoelectric conversion surfaces A of a focusing detection element K for capturing the object image by expanding said range to, for example, the range Qn. If the ring Z is turned to a wide side, the range Q is controlled so as to decrease to, for example, the range Q1, and the surfaces A of the element K are properly selected, whereby the area for detecting the focus is varied. Only the defocusing rate captured by the faces A within the range Qn or Q1 is detected and the automatic focusing is controlled, whereby the accuracy of detection is improved.

Filed: 1987-04-25
Abstract: PURPOSE:To automatically convert an original picture into a picture suitable for facsimile transmission without losing the picture quality of the original picture such as a photograph by generating a prescribed knit pattern and processing the picture data according to the knit pattern. CONSTITUTION:A picture data is outputted from an image scanner and inputted to a terminal T1.

Abstract: PURPOSE:To obtain the manufacturing method of a multilayered wiring board wherein imperfect bonding of a wiring layer and an adhesive insulating layer of a circuit board for an inner layer can be prevented, and treatment agent in the course of manufacturing is hard to be left on the interface of the above layers. CONSTITUTION:When a multilayered wiring board is manufactured by forming an oxide film 2 composed of CuO and Cu2O on the surface by oxidizing a copper foil wiring layer 1 of a circuit board for an inner layer, and by laminating a plurality of said circuit boards via adhesive insulating layers, oxidizing is performed by using alkaline oxidation treatment liquid in which sodium hydroxide of 30g/l or more is contained. The ratio Cu2O/CuO in the oxide film becomes higher than or equal to 80%. When the percentage of Cu2O having large acid resistance is increased, the acid resistance of the oxide film 2 is also increased, so that the oxide film 2 of the wiring layer 1 is hard to be dissolved, when oxidizing is suitably performed in the course of manufacturing a multilayered wiring board. Thereby haloing phenomenon wherein metal copper of the wiring layer 2 is partially exposed can be restrained.
