  • Patent number: 4926540
    Abstract: A motor is equipped with a magnetic structure, stator assemblies having a non-magnetic molding member for being incorporated in the magnetic structure and coils for being wound on the outer periphery of each stator assembly.The magnetic structure is provided with magnetic pole plate bodies, a recess provided in each magnetic pole plate body, bridge members incorporated in the magnetic pole plate body in such a manner as to surround the recess and a plurality of terminal elements whose base ends are coupled to the bridge members and whose free ends are extended toward the recess. The recess, together with the free ends of the terminal elements, is filled with the non-magnetic molding member. On the other hand, the bridge members are not embedded with the non-magnetic molding member but are subsequently cut and removed, so that the base ends of the terminal elements are arranged in such a manner as to project from the surface of the non-magnetic molding member.
    Type: Grant

  • Patent number: 4529552
    Abstract: Composite oxyalkoxides and their derivatives are novel organometallic compounds which give alkaline earth metal titanates such as barium titanate or strontium titanate by hydrolysis or thermal decomposition. The oxyalkoxides are synthesized by the reaction between an alkoxytitanium and an alkaline earth metal hydroxide, and their derivatives are synthesized by the reaction between the composite oxyalkoxide and a chelating agent.

  • Patent number: 4253765
    Abstract: In a multi-wavelength spectrophotometer using a self-scanning detector, the range of wavelengths to be scanned by the detector is divided into plural subranges. These wavelength subranges are subjected to the wavelength scanning with different integration times respectively. The detector output at the scanning of each wavelength subrange is stored in a memory. Thereafter, the stored data is read out in a form of a continuous wavelength range.

  • Patent number: 4030828
    Abstract: There is provided a multi-functional spectrophotometer allowing various measurements in which a stigmatic concave grating is employed for selecting the wavelength of the measuring light. A number of miniature type detectors are employed for detecting the diffracted light from the concave grating. Cells containing samples to be measured can be positioned either adjacent to inlet slits at the side of a light source or behind exit slits. These positions of the cells can be easily changed over one with the other. In the former position, absorbances (concentrations) of sample components for a plurality of predetermined light wavelengths can be simultaneously measured. In the later position, not only the absorbance characteristic curve of the sample can be determined, but also the absorbance, fluorescence and turbidity of the sample for a give wavelength can be measured.
