  • Publication number: 20090128507
    Abstract: The information display apparatus is equipped with: a display unit for displaying a plurality of choice items in the list form; a control unit for controlling an array of the choice items; and a track ball for instructing a coordinate signal. The choice items are displayed in a matrix array constructed of N rows M columns in which the choice items are sequentially arranged from an upper portion to a lower portion of said matrix array, and along right and left directions thereof; magnification is changed based upon a coordinate signal of the track ball along a Y-axis direction; a display screen is scrolled along right/left directions based upon a coordinate signal of the track ball along an X-axis direction; and the matrix array is changed based upon a number of rows to be displayed in correspondence with increased/decreased numbers of the rows.

  • Patent number: 7488533
    Abstract: The present invention relates to amorphous silica particles having high oil absorbance capabilities, a process for their preparation and use thereof. The amorphous silica particles of the invention, wherein oil absorption measured by JISK 6217-4 is more than 400 ml/100 g can be obtained by baking at least 200 to 990° C.

  • Publication number: 20080153694
    Abstract: The present invention provides amorphous silica particles having high oil absorbency and high structural characteristics, wherein the oil absorbency is hardly decreased even when a high load is applied to the amorphous silica particles. In particular, amorphous silica particles are provided, wherein the maximum value of ?Vp/?Rp (where Vp is the pore volume [mm3/g] and Rp is the pore radius [nm]) is 20 mm3/nm·g?1 or more in the pore distribution curve obtained by a benzene adsorption isotherm, and the pore peak radius when the ?Vp/?Rp value is maximum is from 20 nm or more to 100 nm or less.

  • Publication number: 20070059425
    Abstract: The invention provides a fat and oil composition for bakery products, which contains 50 to 85 parts by weight of (A) edible fat and oil wherein the content of unsaturated fatty acid residues in the total constituent fatty acids thereof is 75 wt % or more, 10 to 35 parts by weight of (B) an emulsifier, and 0.1 to 10 parts by weight of (C) a humectant, wherein the (A)/(B) ratio by weight is 6.5 or less, as well as a bakery product compounded with the fat and oil composition for bakery products. The invention also provides use of the fat and oil composition in producing bakery products and a method of producing a bakery product by adding the fat and oil composition to dough.

  • Patent number: 6393299
    Abstract: In radiocommunication apparatus, two downconverters (41, 42) for use in reception system each heterodyne their respective received RF signal to an intermediate frequency. One of the downconverters employs a local signal generated by a synthesizer (19), and the other employs a signal obtained by dividing the frequency of the local signal by a factor of N. Two upconverters (161, 162) for use in transmission system each convert their respective input transmit signal to a transmit RF signal. One of the upconverters employs a local signal generated by the synthesizer (19) and the other employs a signal obtained by dividing the frequency of the local signal by a factor of N.

  • Patent number: 6201952
    Abstract: A first local signal required for a downconverter of a reception system and an upconverter of a transmission system in a first band is generated by a synthesizer for generating a variable high frequency local signal. A second local signal required for a downconverter of a reception system and an upconverter of a transmission system in a second band is generated by mixing a signal generated by an oscillator for generating a signal at a relatively low fixed frequency with the first local signal using a mixer and filtering the result using a high-pass filter.
