Title: Current and voltage sensor
Inventor: TSUJIMOTO YOSHINOBU
IPC: G01R15/24
Filed: 1980-06-20
Abstract: PURPOSE:To make a titled sensor small in size and light in weight and make it strong to vibration and impact by providing a magnetooptic element, an electrooptic element, a polarizing element and a wavelength plate in one piece on a common substrate. CONSTITUTION:The light transmitted through a polarizing element 2 grown epitaxially on a substrate crystal 1 is made into the linearly polarized light polarized in the direction parallel with the substrate. This polarized light enters a magnetooptic element 3, by which it is subjected to the rotation of the plane of polarization by the amount proportional to the magnetic field based on current (i), thence it enters an electrooptic element 4. The voltage to be measured is applied to the electrodes provided on both side surfaces of a waveguide type electrooptic element 4 and the linearly polarized light is elliptically polarized according to the applied voltage. This polarized light is again returned to linearly polarized light by a lambda/4 plate 5. The total of the amounts of rotation of these planes of polarization is detected with an analyzer 2', to detect electric power. Thereby, the sensors having uniform characteristics are obtained in a large quantity and since the controlling of sizes and shapes is easily accomplished, the measuring range of current and voltage is selected freely.

Abstract: PURPOSE:To highly efficiently form a uniform conductive core substance with a smooth surface by inserting a continuous unwoven substance consisting of iron fiber of 2-50mu in fiber diameter using flat plate and grooved endless belts and simultaneously sintering and molding it under the reducing atmosphere. CONSTITUTION:The iron fiber unwoven substance of 2-50mu in fiber diameter with a porosity of 85-98% is inserted in an endless belt consisting of heat-resisting and resistance to thermal shock materials, for example, carbon, silicon nitride ceramic, and silicon carbide ceramic plates. In other words, the continuous unwoven substance is loaded on the lower endless belt 5 with grooves and covered by the smooth upper endless belt 4 which is broader than the width of the grooves. The unwoven substance inserted by the upper and lower belts 4 and 5 is guided into a gas substitution chamber. The air in the unwoven substance is substituted by the mixed atmosphere gas consisting of nitrogen and hydrogen and sintered in the pressure state at high temperatures. As described above, since the fiber unwoven substance is sintered under pressure, a conductive core substance with a desired thickness can be formed by a single sintering.

Filed: 1991-03-25
Abstract: PURPOSE:To make a prompt change to a sheet feeding action for recording again by operating a sheet pressing means and performing sheet pressing control to press a previous sheet of the last sheet when sheets of more than the specified number and less than the number which have been preset for front and back face recording are stacked in a stack means.
