Title: Camera and its manufacture
Inventor: KAWAMATA TADAO
IPC: H04N5/335
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a camera which employs an image pickup element and can simultaneously adjust an optical axis and various functions and to provide the manufacture method and to improve productivity and adjustment precision. SOLUTION: A plurality of printed boards 2 to 4 and an image pickup element printed board 6 which are formed on a printed board 1 are mutually connected by flexible printed wiring boards 8. The lens 10a of a camera main body 10 and the optical axis of an image pickup element 5 as well as the various functions are adjusted by adjusting jigs in a state where the camera main body 10 is fitted to an image pickup element 5 mounted on the image pickup element printed board 6. The various function printed boards 2 to 4 and the image pickup element printed board 6 are detached from the adjusted printed board 1 and they are incorporated into a case and a casing along with the camera main body 10.  Since the optical axis and the various functions can simultaneously be adjusted by the adjusting jigs, man-hours required for adjustment can considerably be reduced compared to a case where the above adjustments are executed by different processing and consequently productivity improves.

Abstract: PURPOSE:To properly eliminate a can from a line for conveying cans at a high speed and to reduce noise in a factory by arranging a linear motor stator for applying the force in the removing direction from a pin to a can, which is fitted to the pin and conveyed. CONSTITUTION:An aluminum can C is conveyed by fitting an opening on one face of the aluminum can C at the tip of one of multiple pins 3 projecting in the horizontal direction from an endless circular chain 1.

Title: X-ray image pick-up tube
Inventor: NISHIKAWA TAKAHISA
IPC: H01J31/49
Filed: 1993-09-27
Abstract: PURPOSE:To realize vertical landing of an electron beam onto a target by arranging a toroidal coil so as to surround an electron beam passage in the vicinity of a field mesh provided on an electron beam incident side of a target. CONSTITUTION:Electron beams generated in an electron gun 3 are deflected by a deflecting coil 5 to scan a surface of a target 2. All the electron beams are directed in the direction perpendicular to the target 2, while the electron beams deflected by a larger angle are deflected larger since a magnetic field of magnetic field intensity proportional to a distance from the center and having the orientation of a concentric circle and in the peripheral direction because of a toroidal coil 7 is generated. Further, due to operation of a field mesh 6, vertical landing of electron beams onto the target 2 can be achieved. In order to enhance accuracy of the vertical landing, it is desirable to vary a current applied to the coil 7 in accordance with an electron beam deflection angle.
