Patent JP-H09233257-A (JP)
Title: Area image sensor
Inventor: KAMIKO MITSUO
IPC: H04N5/372
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To quicken a reaction speed till charges generated in a sensor element are read by a light receiving voltage generating circuit by providing plural control terminals used to control discharging of charges stored in a charge storage means. SOLUTION: Two gates of a charge discharging element whose equivalent circuit is represented by resistors R1 , R2 are selected in place of a multiplexer. Thus, an on-resistance of a multiplexer TFT in each pixel is in total 18MΩ. However, an input resistance of an inverting input terminal of an operational amplifier being a component of a light receiving voltage generating circuit 6 is nearly 0Ω and a resistance of a source wiring is far lower than the on- resistance of the multiplexer TFT, then the effect of a restriction capacitance 40pF onto the source wiring is neglected. Thus, the entire read time depends on a product between the on-resistance value of 18MΩ of the two TFTs and a capacitance 1.2pF of a charge storage capacitor 2.

Title: Connector provided with optical fiber
Inventor: KITAMURA HIDEKAZU
IPC: G02B6/36
Filed: 1986-02-20
Abstract: PURPOSE:To make a connector resistant to heat cycle and make it to fit for use for a long time by using metallized optical fiber and core and fixing them by solder. CONSTITUTION:A conductor (silica fiber) 12 exposed by removing a primary coating 13 and secondary coatings 14, 15 is metallized by nickel plating and gold plating. On the other hand, the tip part 24 and insertion part 23 of a core (fiber guide) are metallized by nickel plating and gold plating, and optical fiber 11 is inserted into the core 22 and soldered, and then, the tip part is polished. As the conductor 12 is fixed by solder 26, change of the tip face does not occur, and as solder 26 is used, little time is required for fixing. Thus, close contact between the core 22 and optical fiber 11 becomes complete, and movement of the fixed optical fiber 11 is prevented even when subjected to thermal effect. Accordingly, reliability is heightened and time for processing is shortened.

Title: Fiber mat and method for attaching metal fitting thereto
Inventor: SAWARA HIROMICHI
IPC: B29C65/02
Filed: 1987-02-17
Abstract: PURPOSE:To prevent uneven strain from generating on the design surface of a product and improve the attaching strength of a metal fitting by a method wherein a fiber mat piece is seated above a fiber mat, and a claw part is forced in from the fiber mat piece side so as to attach the metal fitting. CONSTITUTION:A fiber mat piece 7 is placed on a product 1, which is fixed on the upper part of a fixed block 8 so as to lower a heated metal fitting 2 from above. By actuating a heating device 11 before the lowering of the metal fitting, the metal fitting 2 together with a forcing block 9 is heated up to a set temperature such as 180-230 deg.C. When the metal fitting under the above-mentioned state is lowered, the claw part 4 of the high-temperature metal fitting 2 bites the fiber mat piece 7. At this time, heat is transmitted from the metal fitting 2 to the fiber mat piece 7. The component contained the fiber mat piece 7 is plasticized and thermally deformed by said heat and a pressing force applied with a cylinder 10, resulting in surrounding the claw part 4. When the metal fitting 2 is further lowered, the heat is also transmitted to the product 1, resulting in plasticizing and thermally deforming the surface of the product 1, and welding the metal fitting to the fiber mat piece 7.

Title: Hand-shake detector of camera
Inventor: OOMURA HIROSHI
IPC: G03B17/18
Filed: 1984-02-24
Abstract: PURPOSE:To detect a camera hand-shake and to warn it by processing properly the output signal of a CCD line sensor. CONSTITUTION:A signal processing circuit 8 inputs pieces of information on the shutter speed and aperture value of the camera from a terminal 7 and also inputs information on the difference between the maximum and minimum levels of an output picture signal from a CCD line sensor 1 to determine a level value L and also decide on threshold values L1 and L2 at points I and II of time by subtracting the level value L from the maximum level. A signal processing circuit 3, on the other hand, samples output picture signals of the sensor 1 above the threshold values L1 and L2 at the points I and II of time to obtain sampling signals B and D. The shifting extent of the signal D when the correlation calculated from the signals B and D is maximum corresponds to the amount of picture blur generated between the points I and II of time. A decision circuit 4 compares the picture blur amount calculated by the circuit 3 with the set amount of blur and a driving circuit 5 turns on a light emitting diode 6 when the calculated value is larger to generate a warning.
