Title: Interior quality measuring method for unripe fruit by transmission method
Inventor: OTA TAKESHI
IPC: G01N21/3563
Filed: 1993-04-14
Abstract: PURPOSE:To accurately measure interior properties even if an optical path length of a transmitted light is varied according to a size, a position of an article to be measured by specifying in two wavelength measured absorbance, and then detecting specific properties of a content by a calibration coefficient. CONSTITUTION:A light quantity is first measured as a reference light quantity in a state having no tangerine orange. Then, the orange is set, and its transmitted light quantity is measured. Absorbance in each wavelength is calculated by an equation from the reference light quantity and a transmitted light quantity of the orange. The calculated absorbance is varied depending upon the optical path length of the transmitted light. In order to exclude influence of the optical path length, etc., absorbance values of two wavelengths near the absorption wavelength of sugar are used, and specified by an equation. Sugar content is calculated by an equation from the absorbance obtained by the two- wavelength specification and a calibration coefficient. Since the sugar content obtained in this manner does not depend upon the size and measuring light position of the orange, accurate and stable measurement can be conducted.

Filed: 1984-05-01
Abstract: PURPOSE:To prevent exertion of undue tension on optical fibers during stretching speed by floating stretching bases by gas to make the bases freely movable and moving the stretching bases by means of a weight suspended with wire rods to the stretching bases. CONSTITUTION:The gas is introduced through gas introducing pipes 418, 418a into base plates 410, 410a of a stretching device and the gas is ejected toward the stretching bases 49, 40a when a stretching stage is started. As a result the bases 49, 49a are floated by the gaseous pressure and are made freely glidable and movable on the base plates of the stretching device. The bases 49, 49a are connected to the weight 415 through wires 412, 412a and these stretching bases receive the force in the directions where the bases are parted from each other. When the welded part is heated by an oxygen propane flame burner 48, the bases 49, 49a move toward the direction where the bases are parted from each other by the weight 415. The welded part of the optical fiber is thus smoothly stretched without receiving undue stress.

Title: High density light emitting device
Inventor: MORISHIMA MITSUMASA
IPC: B41J2/455
Filed: 1990-04-03
Abstract: PURPOSE:To enhance the density of light emitting bodies without lowering light emitting strength by providing a waveguide passage in which an adjacent waveguide span narrows more and more from the inlet of light to the outlet of light so that the length in the direction of array of light emitting bodies on the propagation side of light may be shortened. CONSTITUTION:A light converging section 3b is gradually reduced toward its tip in the array direction (width direction) of a LED and a direction (thick direction) orthogonal to the same direction. Similarly, the section 3b is rotated toward its tip and twisted at an angle of 90 degree against a light receiving section 3a at the tip 3c. More specifically, an internal wave guide passage 3d narrows gradually its span with its adjacent wave guide passages toward the tip where the array direction of an LED at the light receiving section 3a is orthogonal to the array direction of an LED at the tip 3c. In this case, the length of the array direction of the LED at the tip is shortened until it becomes identical to the length of a thick direction of the light receiving section 3a. As a result, when light propagates to the light converging section 3b, the length in the array direction of the LED on the wave guide side is gradually narrowed so that the light density may be enhanced substantially without lowering the strength of generation.
