Title: Wafer foreign substance inspecting device
Inventor: MIYATAKE HISAFUMI
IPC: G01N21/94
Filed: 1990-01-31
Abstract: PURPOSE:To make it possible to identify reliably the presence or absence of adhesion of foreign substances by a method wherein one scanning waveform pattern converted by a photodetector is stored and thereafter, an irregular pulse waveform and a pulse waveform, has a regularity, but has a high peak level, which exist in the pattern, are decided as pulse waveforms due to the foreign substances. CONSTITUTION:A laser oscillator 1 is slanted at a proper angle and is fixed, a wafer 3 and the oscillator 1 are moved relatively to each other and the oscillator 1 is moved to scan the surface of the wafer. At this time, reflected light complemented by a photodetector 4 is converted into a current and the current is outputted as a current waveform. This output signal is temporarily stored in a signal storage circuit 5 in every one scanning and is sent to a signal decision circuit 6. Here, in the case foreign substances adhere on a chip 7 and there are foreign substances 9 existing except foreign substances existing t pattern edges, the foreign substances 9 appear as signals 12 due to the foreign substances 9 existing except those existing at the pattern edges. As the waveforms of these signals 12 have not a regular period, the circuit 6 decides the signals 12 as signals due to the foreign substances 9. When the foreign substances are adhered on the pattern edge parts, signals due to the foreign substances overlap with signals 11 due to the pattern edges and appear as signals 13 due to the foreign substances existing at the pattern edge parts. As the peak level of the waveforms of these signals 13 is higher than that of the waveforms of the signals 11, the signals 13 are decided as signals due to the foreign substances.

Title: Method for stabilizing protein in urine, stabilizer, and immunological assay using the same
Inventor: SAKABE KAZUFUMI
IPC: G01N33/53
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To suppress the rise of measured values in the vicinity of neutral to alkali regions by having a bicarbonate compound and an azide and/a chelating agent contained in a urine sample, as necessary. SOLUTION: 50-1,000 mM, preferably 100-200 mM, more preferably 100 mM of a bicarbonate compound is to be contained in a urine sample. When the content of a bicarbonate compound becomes equal to 50 mM or less, sufficient stabilizing effects are not obtained in an acid region. When it contrary exceeds 1,000 mM, further stabilizing effects are not obtained, and dissolvability becomes inferior. By adding an azide in addition to a bicarbonate compound, it is possible to improve the effects of stabilizing protein in urine in the vicinity of a neutral region especially due to urinary sediment. Sediment is generally formed in a neutral region in a urine sample, and measured values rise with this. This sediment is formed by factors such as the types and concentration of salts contained in urine and pH.  It is possible to prevent the formation of sediment by having a chelating agent contained in a urine sample.

Title: Light intensity detector
Inventor: SASAKI KENJI
IPC: G01J1/44
Filed: 1987-02-05
Abstract: PURPOSE:To detect the intensity of light with high resolution by moving two kinds of photodetection bodies which differ in photodetection area optically finely and calculating the intensity of light at a position generated owing to the difference in photodetection area. CONSTITUTION:Array sensors 1 and 2 having elements which are optically as wide as each other and slightly different in length are provided and moved specific times by the length of the difference to detect and store the light intensity in a memory 6, and an arithmetic part 7 calculates it to detect the light intensity in terms of the difference in length. For example, when the sensors 1 and 2 are equal in width and in 3:2 length proportion, the light intensity of the sensor 1 is 72. Then the light intensity of the sensor 2 when the left ends of the sensors 1 and 2 are aligned with each other, the light intensity of the sensor 2 is 57 and when the right ends are aligned with each other, the light intensity is 56. Then the light intensity values on the right and left sides are subtracted from the total light intensity to calculate the value the center part from 72-15-16=41, so that it is considered that a light intensity distribution is detected with area of length 1. Thus, the light intensity is detected within a range smaller than the photodetection area to perform detection with high resolution.
