Title: Optical fiber having low loss at 1,385 nanometer and its production
Inventor: CHANG KAI HUEI
IPC: G02B6/036
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber having low optical transmission loss in the wavelength region of 1,200 to 1,600 nm and particularly at 1,385 nm, in the correlation of optical transmission loss with wavelengths of transmitted light and also to provide the production of the optical fiber. SOLUTION: This production comprises: forming a core rod 20 by a vapor- phase axial deposition method so as to have a (deposited clad)/core ratio (D/d ratio) of <7.5; dehydrating the formed core rod 20 at about 1,200 deg.C in a chlorine- or fluorine-containing atmosphere; then, solidifying the resulting porous soot base material of the dehydrated core rod 20 in a helium atmosphere to convert it into glass; extending the solidified core rod 20 with an oxygen- hydrogen torch(s); and finally, inserting the extended core rod 20 into a glass tube 40 having a low OH content and then, pressing the glass tube 40 on the extended core rod 20 to form a preform.  By producing an optical fiber from this preform, the optical transmission loss at 1,385 nm of the optical fiber is reduced to a level lower than the loss level at 1,310 nm and light in the whole wavelength region of 1,200 to 1,600 nm becomes suitable for optical transmission using the optical fiber.

Title: Documentation device
Inventor: FUKUSHIMA HIDEO
IPC: G06F17/22
Filed: 1986-07-22
Abstract: PURPOSE:To make it unnecessary to handle numerical values similarly to Hiragana (cursive form of Japanese syllabary) to improve operator's convenience for use by seeing the character just preceding Hiragana reading to judge whether the numeric processing should be performed or not. CONSTITUTION:Kanji (Chinese character) conversion instructing information from an input information control circuit 12, Hiragana input start position information from a display picture control circuit 14, and information of the number of characters on one line from a document memory control circuit 15 are inputted to a numeric clause deciding circuit 16. The deciding circuit 16 reads the character just preceding the Hiragana input start position from a document memory 18 based on these information and decide whether this character is a numerical value or not and outputs information indicating whether a character string to be converted as a numeric clause or not. If it is decided by the deciding circuit 16 that it should be converted as a numeric clause, a Kanji (Chinese character) phrase converting circuit 19 reads out Hiragana reading following the numerical value from a Kanji phrase dictionary 20 as a suffix to perform Kana (Japanese syllabary)-Kanji conversion. Thus, it is unnecessary to handle numerical values similarly to Hiragana, and operator's convenience for use is improved.

Filed: 1992-06-30
Abstract: PURPOSE:To obtain a functional cross-linked-polyolefin molding in which the cross-link density of the polymer varies from part to part by bringing a molding containing a specific copolymer into contact with a catalyst in a specific manner. CONSTITUTION:Part of a molding made from a copolymer of an alkenylsilane [e.g. a compound represented by formula I (wherein n is 0-12, p is 1-3, and R is a 1-12C hydrocarbon group), such as vinylsilane] with an olefin [e.g. a compound represented by formula II (wherein R is H or a 1-12C hydrocarbon group), such as ethylene or styrene] is immersed in a catalyst solution, while another part is immersed in a catalyst solution having a different catalyst concentration. Thus, the copolymer is cross-linked unevenly to obtain a functional cross-linked-polyolefin molding in which the cross-link density of the copolymer varies from part to part and which therefore is extremely suitable for a particular use.

Abstract: PURPOSE:To make it possible to copy any number of sheets by one-time copy setting without jamming by discharging the excessive number of copied sheets in a bin by way of transferring to an overflow processing when non-sort mode using only a main tray is selected and a number of sheets exceeding the capacity of this tray are to be copied. CONSTITUTION:At the time of sort mode, by the ascent and descent of a plural number of bins 32, copy paper sheets are discharged in the relevant bins 32. Subsequently, in the case when non-sort mode using only a main tray 33 is selected while a number of paper sheets exceeding the capacity of the main tray 33 are to be copied, they are transferred to an overflow processing and the excessive copied sheets are loaded in a bin 32 right under the main tray 33. When they exceed the capacity of this bin 32, paper sheet discharging processing is practiced with another bin right under it further. Consequently, even in the case when the number of copy sheets exceeding the capacity of the main tray 32 is set, all the number of sheets can be smoothly copied without jamming by one-time copy setting.
