  • Publication number: 20100026867
    Abstract: A pixel signal obtained by imaging with a solid-state image sensor element can be output selectably either in n bits or in a bit number of an integral multiple of n in synchronization with an output clock. A clock converting unit (26), an allocating unit (32), a first selector (31), a second selector (27), and an output mode control unit are provided for the purpose. The allocating unit (32) allocates respective bit data of pixel signal obtained by imaging with the solid-state image sensor element into at least two series of bit data alternately, in synchronization with clock converted by the clock converting unit (26). The first selector (31) selects an output from the bit data allocated by the allocating unit (32) and the bit data not allocated by the allocating unit (32). The second selector (27) selects an output from a clock with a frequency converted by the clock converting unit (26) and a clock with a frequency not converted by the clock converting unit (26).

  • Patent number: 5773066
    Abstract: Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered. The first water addition is to cause the raw wheat grains to have a water content of 12-14%. The tempering of the raw wheat grains is performed for 16-36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains. The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content.

  • Patent number: 5573798
    Abstract: This invention relates to a pH measuring electrode having a sensor film which is sensitive to a hydrogen ion (H.sup.+) in the solution. The pH measuring electrode of this invention has a sensor film of a metal oxide deposited on an electrically insulative ceramics substrate so that the sensor film can be very miniaturized in its size. Therefore, the entire pH measuring electrode can be made considerably small and simple in construction. Also, this invention provides another pH measuring electrode which further includes a porous film of an insulation material coated on the surface of the metal oxide sensor film so that the sensor film is not affected by any coexistent substances.
