Title: Luminescence-type immunoassay device
Inventor: YOSHIDA MASAKAZU
IPC: G01N33/543
Filed: 1992-09-07
Abstract: PURPOSE:To measure immunoassay accurately by adjusting the spectral transmittance of a dichroic mirror by eliminating the offset noise light due to Raman scattering light components. CONSTITUTION:A dichroic mirror 7 has a light transmittance of 10%, or less each for a wavelength of approximately 500nm or less and approximately 570nm or more. Excitation light entering a slab-type light waveguide path 10 excites a fluorescent substance on the surface and generates fluorescence and the fluorescence is emitted from a refraction type coupling prism 11 and then contains noise light including Raman scattering light. The light impinges on the dichroic mirror 7 again, reflects and eliminates the offset noise containing the Raman scattering light content with a wavelength of approximately 570nm and then enters a photoelectron multiplication tube 16 via a flat convex lens 14 and a color glass filter 15. The filter 14 fully cuts noise light at a short wavelength side, for example, that with a wavelength of approximately 490nm. Therefore, by forming the mirror 7 to be a band-pass filter, noise light with its wavelength being closer to fluorescence can be eliminated without losing the signal light intensity, thus effecting immunoassay accurately.

IPC: H02P27/06
Filed: 1994-10-03
Abstract: PURPOSE: To provide an output voltage detector for an inverter capable of detecting with a high accuracy the fundamental wave of an output voltage of the inverter containing many harmonics. CONSTITUTION: An inverter 21 converts a DC supply voltage to a three-phase AC voltage in accordance with the control command from a control circuit 30 and outputs it from output terminals 24a to 24c.

Title: Detecting method for reference line of fatigue test piece
Inventor: SANO KAZUO
IPC: G01N3/32
Filed: 1985-10-25
Abstract: PURPOSE:To detect securely a position suitable for a fatigue test within reference line width by finding the mean density level in the same direction with a reference line from a video signal obtained by picking up the image of a fatigue test piece and subjecting to a binarization processing based on a specific threshold level. CONSTITUTION:A horizontal integration circuit 34 calculates the integral value of the luminance level of the video signal of a scribing line in the same direction with the scribing line and then finds its mean value. This mean luminance level is sent to a binarization circuit 35 and converted into a binarization signal based on the threshold value corresponding to the lower end position of the scribing line. Then, a masking circuit 36 masks the mean brightness level with the binarization data. This data is sent to a maximum level position detecting circuit 37, which detects the maximum level of the data, i.e. a high level position P corresponding to the scribing line and removes other high level parts. Thus, a scribing-line lower position detecting circuit 38 receives the masking processing data and the data of the position with the highest level p to detect the lower end position G of the scribing line.

Filed: 1986-10-09
Abstract: PURPOSE:To prevent the shock due to speed change, by controlling the operating timing, in which timing valves are changed over to the second position, on the basis of the rotating condition of the input shaft of a transmission. CONSTITUTION:On a torque converter 1, a revolution sensor 201 which detects the rotating condition of an input shaft is provided, and the output from the revolution sensor 201 is input into a control circuit 200, and further the operating timing in which timing valves 103, 104 are changed over to the second position is controlled on the basis of the signal from the revolution sensor 201. Thus, since the operating timing of actuators 101, 102 at the time of shift-down is always in an optimum condition, the sudden rise or fall of turbine revolutions due to the deviation in timing when the dispersion or the change with the passage of time is caused in the response time of a transmission, or the output of an engine, or the like can be prevented, so that the occurrence of the shock due to speed change can be eliminated.

Abstract: PURPOSE:To transmit picture information by time-division on the same telephone line with a supervisory diagnostic data of an elevator and a voice data from an interphone in a riding cage by digitalizing the picture information in the riding cage of the elevator to be compressed. CONSTITUTION:In a two-dimensional picture, a gradation level of a picture element P can be shown by an anticipation expression of P=alphaA+betaC+gammaD.
