Inventor: SUGAYA ISAO
IPC: C01B33/113
Filed: 1981-12-07
Abstract: PURPOSE:To efficiently concentrate objective impurities in a sample by bringing HF vapor generated from a treating agent into contact with the sample to vaporize Si as the principal component of the sample as SiF4 and to leave the impurities. CONSTITUTION:When traces of impurities in a high purity material contg. Si (and/or SiO2) as the principal component such as silicon for a semiconductor or quartz glass for an optical fiber are analyzed, in order to concentrate the impurities, the high purity material (sample) is treated to vaporize Si as SiF4. For example, a platinum vessel 2 holding the sample 1 is mounted on a support 4 in a polyethylene container 3, a treating agent 5 which generates HF vapor on being heated such as a hydrofluoric acid soln. is charged into the container 3 while avoiding direct contact with the sample 1, and the container 3 is tightly sealed. The container 3 is then put in a thermostat 6, the sample 1 is treated with HF vapor generated from the treating agent 5 to vaporize Si, and impurities remaining in the vessel 2 are analyzed.

Title: Method for processing silver halide color photographic sensitive material
Inventor: SAKAGAMI MEGUMI
IPC: G03C7/42
Filed: 1988-08-05
Abstract: PURPOSE:To make it possible to shorten the bleaching time of the subject material, and to prevent the generation of a faulty desilverization and the discoloration of a color picture in the material by incorporating a specified compd., in the photosensitive material and processing the material with a specified bleaching solution. CONSTITUTION:The photosensitive material contains at least one kind of the compd. capable of being released a bleaching promoter by allowing the compd. to react with the oxidant of a developing main agent at the time of developing the material. And the bleaching solution contains a ferric complex salt of 1,3-diaminopropane tetraacetic acid of >=0.2mol/l as a bleaching agent, and has pH of 2.5-5.5. When the compounding amount of the ferric complex salt is <0.2mol/l, the beaching speed of the material slows down rapidly, and the stain of the material after processing it, increases. The rapid desilverization of the material and the complete recoloring of a cyan dye are attained by specifying the pH of the bleaching solution to <=5.5. The preferable range of the pH for displaying the bleaching effect is 5.0-3.0, further preferably 4.5-3.5. Thus, the bleaching speed of the material having sufficient level in practical application is obtd., even at the time of rapidly processing the material with a bleaching bath, and the side effect of the bleaching processing such as the discoloration, etc., of the color image is suppressed, and the rapid bleaching speed of the material is obtd.

Filed: 1993-08-06
Abstract: PURPOSE:To reduce the segmentation of syllables and dictionary retrieval that are not necessary. CONSTITUTION:When a phonetic symbol string to be converted is inputted, a dictionary word length retrieval part 11 takes information on corresponding word length out of a dictionary word length information part 12 for the respective syllables of the inputted phonetic symbol string. A conversion control part 13 gives priority to a syllable which is large in word length value first and to a syllable which is inputted earlier secondarily on the basis of the taken-out information on the word length, and segments a phonogram string of word length succeeding the syllable as an object of retrieval at the dictionary part 15. Thus, the phonogram string is outputted after being converted into words retrieves by a dictionary retrieval part 14. Consequently, efficiency such as the speed of Chinese character conversion and the accuracy rate is improved.

Abstract: PURPOSE:To reduce variation in the impressed pressure difference between the two ends of a spool and accomplish a good controlling performance for the damping force by introducing stable internal pressure of a lower fluid chamber to the lower space, upper space, and back pressure chamber via an aux. flow-path. CONSTITUTION:The upper space 3a in a valve member 3 leads to the lower space 3b via a through hole 321 in a bulkhead 32 constituting part of an aux. flow-path 21, which is leading from the upper space 3a to a back pressure chamber 2c formed behind an aux. piston 5. A fluid supply path 24 extends downward from the other side wall of this back pressure chamber 2c to be open at the bottom wall of an enclosed chamber 2b, and on the way of this path 24 a check valve 22 is installed, which is opened when the internal pressure of the enclosed chamber 2b is lowered relatively. The side wall of the back pressure chamber 2c is penetrated by a bubble exhaust path 25 in a position near the top, which opens at the main flow-path part 11a. Thereby spool variation during operation is prevented effectively to accomplish stable control of the damping force, and also bubbles generated around the valve member are hindered from intruding to the enclosed chamber effectively, thus avoiding degradation of the displacement enlarging efficiency.
