Title: Magnetic field sensor
Inventor: OGA SUEYOSHI
IPC: G01R33/04
Filed: 1990-05-29
Abstract: PURPOSE:To reduce the size of the sensor which uses one detection coil by controlling the rotational angle of magnetism of a magnetic core which varies with a magnetic field to be detected to a constant angle. CONSTITUTION:A wire of amorphous alloy is formed in a U shape to constitute the magnetic core 1A and when a control current of frequency f0 is fed from an exciting circuit 2, a detection coil 3A wound around the magnetic core 1A detects a signal S1; and an amplifying circuit 8 amplifies the signal S1 and inputs a signal S2 and its inverted signal S3 to a synchronous rectifying circuit 9, which generates a voltage signal S4 rectified synchronously with a frequency 2f0. An integration circuit 10 compares the signal S4 with a reference voltage signal S8 to eliminate a bias voltage component and outputs a signal S5 generated by integrating only the signal component of an external magnetic field Hex to an adding circuit 11, which adds a bias current S6 to the signal S5 to generate a signal S7; and the signal S7 becomes a signal IFB by voltage/current conversion and is fed negatively back to the magnetic core 1A. Consequently, the magnetism rotational angle of the magnetic core 1A becomes constant and the coil 3A has three functions for magnetic field detection, biasing, and negative feedback, so a detection part is reducible in size.

IPC: B23K15/00
Filed: 1979-10-29
Abstract: PURPOSE: To eliminate completely scattering materials flowing into the electron beam generator to make a long-time continuous processing possible without causing the discharge phenomenon, by connecting the vacuum exhaust pipe near the electron beam deflection point of the guide pipe.  
     CONSTITUTION: Material 5 to be processed is positioned in vacuum room 1, and vacuum room 1 and electron beam generator 6 are kept in a prescribed vacuum state. Electron beam 10 is covered with guide pipe 11 and is deflected by deflecting mechanisms 8 and 9 and is irradiated to the processing position. Scattering materials such as metal vapour and metal particles generated at the processing time go almost straightly through guide pipe 11 and go straightly in vacuum exhaust pipe 12 opening near deflecting mechanism 9. Air in pipe 12 is exhausted, and therefore, almost all scattering materials are transferred to the vacuum exhaust device through pipe 12. Consequently, scattering materials which reach electron beam generator 6 through the bending part of guide pipe 11 are eliminated completely, and the periodical elimination work of scattering materials is unnecessary.

Abstract: PURPOSE: To make it possible to fix an adapter into an effective image device smaller than the originl effective image size by inserting a lens system having a positive refractive index as a whole into the adapter for mount conversion, making the focal distance of an objective lens short, and reducing the F number.  
     CONSTITUTION: Adapter for mount conversion of this invention is used when, for instance, the convertible lens of 35mm camera is fixed into cine camera, and TV camera, etc. Lens system 7 which has a positive refractive index as a whole is inserted into the adapter 4 for mount conversion. Besides, 5 is the first mount which matches with objective lens 1, and 6 is the second mount suitble for optical device. 5 and 6 are different mounts. By this constitution, the adapter itself has relay multiplication. As this relay multiplication is less than 1,the focal distance of the objective lens is shortened, and at the same time, F number is reduced. In  other words, the inherent image angle of the objective lens can be effectively used,  hence a bright lens system can be obtained.
