Title: Terminal part of optical fiber
Inventor: MIYAKE YOSHIO
IPC: G02B6/42
Filed: 1981-08-17
Abstract: PURPOSE:To eliminate the reflection in the terminal part of an optical fiber without degrading characteristics of the optical fiber, by connecting optical glass, which has a refractive index approximately equal to that of the optical fiber core, to the obliquely formed end face of the optical fiber. CONSTITUTION:An optical fiber 1 and a glass block 2 are connected on a junction face 3 formed obliquely to the axis of the optical fiber. The other face 4 of the glass block 2 is so coated that a used light wavelength is not reflected, and refractive indexes of the glass block 2 and the optical fiber core are set to the same value. Consequently, even if a luminous flux 11 incident to the optical fiber 1 is reflected partially by discontinuity of refractive index, a reflected luminous flux 12 is much deviated from the fiber optical axis and is easily eliminated because a boundary face 3 is formed obliquely to the fiver optical axis, and as the result, the reflection in the terminal part of the optical fiber is eliminated effectively to obtain a stable optical circuit.

Title: Structure of slide valve for high temperature service
Inventor: TAJIRI KAZUMI
IPC: F16K3/02
Filed: 1990-05-18
Abstract: PURPOSE:To absorb any harmful influence due to differential thermal expansion by attaching each ceramic plate to the metal base of a valve element so as to form a specified clearance in space between the ceramic plates adjoining with each other in a cold state at time of disuse. CONSTITUTION:The tip of a valve element 4 is covered with plural ceramic plates 14 with abrasion resistance, and each ceramic plate 14 is clamped to a heat resistant base plate 15 welded to the valve element 4 with a securing pin 16. In addition, a ceramic cap 17 is installed as covering a head part of the securing pin 16. Each ceramic plate 14 is attached to the ceramic plate 15 so as to get a specified clearance 19 formed between ceramic plates adjoining to each other in a cold state at time of disuse, namely, at the initial state. The valve element 4 is retractable by operation of a valve stem, and thereby a flow rate is controlled but a wearing action works strongly at a tip part of the valve element 4 in particular. However, the tip of the valve element 4 is ensured with abrasion resistance by the ceramic plate 14, through which a thermal expansion difference to be produced between the ceramic plate 14 and the base plate 15 at time of use at high temperature is well absorbed by the clearance 19.

Title: Measurement of vapor concentration of hydrogen peroxide for sterilization by near infrared-ray spectrochemical analysis and sterilization method
Inventor: RAIAN BUAN DEN BAAGU
IPC: G01N21/35
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To measure hydrogen peroxide accurately under presence of steam by measuring the absorbance in a wavelength region where hydrogen peroxide exhibits high absorbance and correcting the measurement by subtracting the absorbance of steam measured in other wavelength region. SOLUTION: Absorbance is measured for a gas sample above a sterilization chamber containing vapor of hydrogen peroxide and steam in a wavelength region of 1420nm where hydrogen peroxide exhibits high absorbance. Absorbance of steam is then measured in one or a plurality of wavelength regions of 1350-1400, 1830-2000 and 915-950nm where hydrogen peroxide transmits the light (or does not absorb the light) thus calculating the absorbance at 1420nm. It is then subtracted from the absorbance of hydrogen peroxide measured previously in same wavelength region thus determining the absorbance only of hydrogen peroxide. According to the method, concentration of hydrogen peroxide can be calculated easily using Pierce's rule.
