Title: Preparative liquid chromatograph
Inventor: IWATA YOUSUKE
IPC: G01N30/80
Filed: 2000-07-14
Abstract: PROBLEM TO BE SOLVED: To fractionate a target sample component in analysis wherein a base line level fluctuates with good reproducibility. SOLUTION: Only a mobile phase is allowed to flow under the same analyzing condition as actual analysis and a base line chromatogram is obtained on the basis of the detection signal at this time by a chromatogram forming part 3 to be stored in a memory part 5. The actual analysis is started and the chromatogram forming part 3 reads the base line chromatogram from the memory part 5 and subtracts the detection signal value in the base line chromatogram, which corresponds to the successively obtained detection signal value of a detector, from the detection signal value of the detector to successively form a difference chromatogram. The fluctuation of the base line level is small in the difference chromatogram.  A peak recognition part 7 reads a preset fractionation signal level and a fractionation signal inclination value from the memory part to recognize a peak in the successively formed difference chromatogram.

Title: Cam follower
Inventor: MOTOHASHI NOBUTSUNA
IPC: F01L1/18
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To enhance the wear resistance of a roller and a cam in a cam follower by preventing edge loading when the roller is tilted, while enlarging the area of contact when the roller assumes a proper attitude. SOLUTION: In the cam follower 6, the roller 9 is rotatably mounted on a shaft 8 bridged across two opposing supports 7 and 7. A compound crowning surface consisting of a smoothly continuing curved surface is formed on the outer peripheral surface of the roller 9 by inscribing a small-diameter crowning surface 13 to each end of a large-diameter crowning surface 12. Thus, even if the roller 9 is tilted because of misalignment, edge loading whereby contact stresses are increased at one axial end, as would occur in a conventional cam follower having a uniformly curved crowning surface, can be prevented.

Title: Non-linear compensator
Inventor: SUGA TAKU
IPC: H04N5/00
Filed: 2000-07-27
Abstract: PROBLEM TO BE SOLVED: To adaptively compensate non-linear characteristics and phase rotation with simple adjustment. SOLUTION: The digital base band signals of the RF input and the RF output of an RF amplifier are extracted by an input demodulation part A and an output demodulation part B. A delay detection part E detects the time difference and the phase difference of both signals by a correlation operation. A delay adjusting part C synchronizes both signals and the phase shifter of the output demodulation part B adjusts the phases. A distortion detection part F obtains the amplitude error and the phase error of both signals and inputs them to a distortion correction part D as distortion components in the state.  The distortion correction part D sequentially selects amplitude corresponding to an amplitude value, the phase and compensation quantity from compensation quantities which are registered in an initial stage and are adaptively updated, compensation quantity is added to the digital base band signal obtained by the input demodulation part A. Thus, the distortion component is compensated, and an output conversion part G converts it into an original signal format and outputs it to an RF amplifier 3. Thus, the non-linear characteristic and phase rotation can adaptively be compensated with simple adjustment.

Title: InGaN LIGHT-EMITTING DIODE
Inventor: KAWAKAMI YOICHI
IPC: H01L33/32
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To provide an InGaN light-emitting diode which efficiently emits light in a red color band and moreover with spectrum distribution being relatively broad for emission. SOLUTION: The light-emitting layer of a light-emitting diode, which is represented by a general expression InxGa1-xN (0<x<1) is doped with other V-group atoms as an isoelectron trap formation element substituting for an N atom. As the V group atom substituting for N, P (phosphorus), As (arsenide), Sb (animony), and Bi (bismuth) are used. The substitution factor for the N atom is 1% or less, preferably with 0.5% or less. In short, the light-emitting layer of the light-emitting diode is represented by a general formula InxGa1-xN1-yXy (0<x<1; X=P, As, Ab, Bi; y=0<y<0.01/0<y<0.005). The substitution atom acts as an isoelectron trap. The force of the isoelectron trap attracting an electron or hole is essentially based on the difference in the number of orbits of an inner shell electron, and its affecting range is very short being about the Bohr radius. In this respect, it differs much from a long-range electrostatic potential formed by a donor and acceptor of a mixed crystal.

Abstract: PROBLEM TO BE SOLVED: To achieve a temporary stopping of identifying information after a ready-to-win display pattern occurs and allow players to easily recognize the timing thereof by a voice. SOLUTION: A ready-to-win display pattern occurs at a stage where right and left patterns individually varying are temporarily stopped within capsules 51a and 51c (b). Then, after a character pattern 53 for presentation performs a specified action, a voice of 'magical beam' is outputted as indicated in a balloon 53b. At this time point, a light image 52 is displayed on the circumference of the capsule 51b and the variable display speed of the middle pattern varying in the image is lowered (c). In this manner, the middle pattern is temporarily stopped. If the middle pattern within the capsule 51b fails to temporarily stop at a predetermined frequency, variable display thereof is performed again, and then, the pattern is forced to temporarily stop following the action of the character pattern 53 and the outputting of the voice (e) to (f).
