Abstract: A pyroelectric infrared sensor for use in intrusion alarm systems, including a pyroelectric ceramic element provided with two pairs of electrodes, of which the front electrodes are so configured as to permit a simplified printing process for higher productivity and lower production costs. The front electrodes each have a first region overlapping with a part of one of the back electrodes and a second region overlapping with a part of the other of the back electrodes, and are arranged adjacent to each other and are electrically insulated from each other. The first regions and the second regions of the front electrodes have a ratio of areas of approximately 1:1.

Abstract: A method of charging molten metal into a vertical die casting machine, wherein molten metal is introduced into a lower sleeve in which a lower plunger is slidably received, to store therein a mass of molten metal having a surface level not higher than the bottom of a molten metal inlet to a mold cavity. Next, an upper plunger is lowered to a predetermined position, raising the lower plunger to urge the molten metal upwardly and move it into the mold cavity. The upper plunger can then be moved to apply pressure to the molten metal. The method ensures smooth charging of molten metal and casting of a product free of casting defects.

Abstract: Methods and systems for measuring the temperature and spectral factors of a number of specimens (or radiators). The radiant flux from the specimens are spectrally analyzed with respect to effective wavelengths from M different channels (M being greater than or equal to 3). A relation among the spectral radiant flux intensity, approximated spectral factor (depending only on wavelength) and the temperature is determined for each channel by using Planck's radiation law with the condition that a relation N+K=M is kept among M of the number of channels, N of the number of specimens with unknown temperature values and K of the number of unknown terms of the approximated spectral factor of the specimens. Strict algebraic development of such relation is employed to cancel out all of the unknown terms of the spectral factor to obtain a one-dimensional equation concerning the sole temperature.
