Title: Position detection device of robot in metallic conduit
Inventor: SUYAMA KIICHI
IPC: F16L55/18
Filed: 1995-01-17
Abstract: PURPOSE: To improve detection precision by constituting a device by way of setting central frequency of an emitted electric wave at an intermediate value of cutoff frequency of each waveguide mode of the lowest and next to the lowest in a metallic conduit. CONSTITUTION: An FM signal emitted from a transmitting antenna 3 to the inside of a metallic round conduit M is propagated in the conduit M at the lowest mode TE11 , and a reflective wave of a robot is propagated in opposite direction in the conduit M at the mode TE11 and is received by a receiving antenna 4. Thereafter, it is supplied to an input terminal of a mixer 5 and mixed with an FM signal supplied to the other terminal from a distribution circuit 2. The FM signal supplied to each of the input terminals of the mixer 5 is slipped in time by reciprocal propagation required time for the FM signal emitted from the antenna 3 to the robot R. Consequently, the mixer 5 generates a beat signal of frequency in proportion to the propagation required time.  A distance to the robot R is calculated by converting this beat signal to frequency spectrum by a high speed Fourier conversion circuit 6 and analyzing the frequency spectrum by a CPU 7.

Title: Video signal processor and its method
Inventor: SAKASHITA YUKIHIKO
IPC: G09G3/36
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To display an image at a low cost with an excellent moving picture display characteristic where no line flicker is remarkable based on a video signal of the interlace system by comparing a scanning line signal between fields to discriminate whether the video signal depicts a moving picture or a still picture and displaying the video image with resolution optimum to a characteristic of the input video signal. SOLUTION: When a moving picture/still picture discrimination circuit 10 discriminate an input video signal to be a moving picture, a magnification/reduction processing circuit 9 magnifies the signal for each field at a multiple of 3.2 to convert number of horizontal lines, 240 into 768 lines and displays the resulting signal on an LCD 12. When the moving picture/still picture discrimination circuit 10 discriminates the input video signal to be a still picture, a de-interlace circuit 8 alternately reads a scanning signal of consecutive odd numbered and even numbered fields for each scanning line from a storage means that stores interlaced consecutive odd and even numbered field scanning line signals to configure a image whose horizontal line number is 480.  The signal is converted into a video signal whose horizontal line number is 768 by magnifying the image whose horizontal line number is 480 at a multiple of 1.6 and the converted signal is displayed on the LCD 12.

IPC: F01D5/20
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To improve heat transfer coefficient by promoting convection at the internal part of the moving blade, to improve the cooling effect of a shroud, and to improve the cooling effect of the whole of the moving blade. SOLUTION: The internal part of a moving blade 1 forms an internal cavity throughout a whole length and a number of pin fins fixed on the two wall surface of an internal cavity are mounted on a whole wall surface. An enlargement cavity 6 is arranged at the internal part of a shroud 2 at the tip part of the moving blade 1, and a cooling air is caused to flow out downward of the shroud 2 through holes 7 from the periphery of the enlargement cavity 6.
