Abstract: PROBLEM TO BE SOLVED: To provide an optical synthetic quartz glass excellent in light transmittance, optical homogeneity and optical stability and highly resistant to a laser, its production method and an optical member for an excimer laser. SOLUTION: The synthetic quartz glass is formed by directly vitrifying the silica fine particle obtained by the flame hydrolysis of an organodisilazane compd. on a preform, and its birefringence is controlled to <=5 nm/cm and the refractive index difference (Δn) to <=2×10<-6> . The synthetic quartz glass is produced by introducing an organodisilazane compd. expressed, by (R<1> )3 SiNHSi(R<2> )3 into a flame 2 consisting of a combustion gas and a combustion supporting gas, depositing the formed silica fine particle on the rotating heat- resistant preform 1, melting and vitrifying the particle. In the formula, R<1> and R<2> are hydrogen and 1-3C univalent aliphatic hydrocarbonic groups which can be the same or different. The optical member for an excimer laser is produced from the synthetic quartz glass.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix. According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix. Another aspect of the present invention involves a device for the measurement of a serum or plasma sample, utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and eguivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis. A further aspect of the present invention provides a porous reagent delivery system comprising a matrix of sintered porous material containing at least one reagent in a freeze-dried state, and method for making same. The system allows the delivery of a unitized form of a freeze-dried reagent which is recoverable upon contact with a liquid.

Abstract: This invention relates to an optical recording member, its production and an optical recording card produced by utilizing them, wherein a blackened silver particle-containing layer is disposed on a substrate and a pigment layer absorbing a near infrared ray is disposed on the silver particle-containing layer. In the optical recording member having such a structure, when a laser beam having an optical energy density above a threshold value of a predetermined optical energy density as a boundary is applied, the optical recording member consisting of the silver particle-containing layer and the pigment layer deforms in a projection shape so that this deformed portion can be utilized as an optical recording pit. In the optical recording member of this invention, the recording pit thus formed is detected by the existence of reflection of a read beam and an optical recording data is read out. However, even when the optical pit is repeatedly radiated many times with a read beam consisting of a laser beam having an energy density below the threshold value, the optical recording pit does not deform so that the signal-to-noise ratio (S/N) of the signal does not drop with time.

Abstract: Disclosed is a mode field modifier (40) for use with an optical fibre (54) having a core (56) and a cladding (58) of outside diameter d. The modifier comprises a modifier core (42) having a refractive index n1. Surrounding the modifier core is first cladding layer (44) having a refractive index n2 that is less than n1. On the surface of the first cladding layer is a second cladding layer (46) having a refractive index n3 which is less than n2. The modifier is tapered intermediate its ends whereby it has a large diameter end and a small diameter end. The diameters of at least the core and first cladding layer at the large diameter end are greater than the corresponding diameters at the small diameter end. The diameter D1 of the first cladding layer at the large diameter end is greater than d. An axially disposed hole (52) in the large diameter end receives a fiber (54) which is held in such alignment with the mode field modifier (40) that it is in light coupling relationship with the modifier core (42). The mode field of a signal coupled from the fiber to the mode field modifier expands as it propagates through the tapered portion of the modifier to the small diameter end. An in-line coupler between two optical fibers is effected by connecting together in axial alignment two such mode field modifiers with their small diameter ends adjacent one another.
