Patent JP-H0818561-A (JP)
Title: Address comparison method for repeater
Inventor: ISHIBASHI MASAFUMI
IPC: H04L12/28
Filed: 1994-06-27
Abstract: PURPOSE:To reduce number of times of address comparison by comparing a low-order digit of each address with a low-order address of a destination address simultaneously for each prescribed number of addresses stored in an address table and comparing all digits of the addresses whose low-order digit is coincident with all digits of the destination address. CONSTITUTION:A low-order digit 109 of a destination address is arranged to each part of an address comparator section 104b and the digit 109 is compared simultaneously with the low-order digit of 6 consecutive addresses in this case in the address table. When no low-order digit coincident with the digit 109 is in existence, the digit is compared simultaneously with succeeding 6 addresses. So long as no coincident low- order digit is in existence, the 6 addresses are compared similarly for their low-order digit. When any coincident low-order digit is in existence, all digits of the coincident address are arranged in the address comparator section 104a and compared with a full digit of a destination address in a destination address detection section 103. When the full digits are coincident, the result of retrieval in a form of a relay destination segment decision signal 107 is informed to a relay destination segment changeover section 102. Thus, number of address comparator circuits is reduced to reduce the retrieval time.

IPC: G01N1/28
Filed: 1994-06-03
Abstract: PURPOSE:To quickly and accurately quantify the micro content of an element by electrolyzing a glass phase carbon material in an alkaline solution to prepare a slurry type sample, and directly analyzing the sample with a flame-less atomic absorption spectrum method. CONSTITUTION:A glass phase carbon, material 1 is immersed in an alkaline solution 3, using a clean platinum plate 2 as a negative electrode, and DC voltage is applied thereto for electrolyzing the material 1. Furthermore, aqueous ammonia giving high electrolytic efficiency and allowing the easy preparation of slurry is used as the solution 3. Also, the concentration of the aqueous ammonia is preferably taken at 5mol/l or more, and the temperature thereof is adjusted to 50 deg.C or higher. An optimum voltage range varies, depending on various conditions and, therefore, applicable voltage is set lower within a range for causing electrolytic reaction. Voltage, when applied, generates the concentration of electric field upon impurities, defects, irregular sections or the like, and collapsed separation is generated in a specimen. Thus, carbon powder is suspended to form slurry. Thereafter, a flame-less atomic absorption spectrum analysis device is directly set to the slurry to quantify the impurities contained therein.

Abstract: PURPOSE:To obtain an image excellent in granularity by using inexpensive toner by minimizing the grain side distribution range of magenta toner and its average grain size. CONSTITUTION:The degree of contribution of respective color toners to the granularity of a color image is approximately set up to '1' in yellow toner, '5' in cyanine toner and '10' in magenta toner.

Thereby, the grain size distribution ranges of color toners to be used for development are set up to 4-8mum in the magenta toner, 4-13mum in the cyanine toner and 4-18mum in the yellow toner. Thus, color images excellent in granularity can be obtained without increasing the production cost of toner.
