IPC: A61K36/06
Filed: 1983-12-28
Abstract: PURPOSE:A chemically modified polysaccharide useful as a lowly toxic antineoplastic agent, prepared by combining a main chain having a glucopyranosyl group unit as a repeating unit with a specified second repeating unit and, if necessary, a specified third repeating unit. CONSTITUTION:A chemically modified polysaccharide comprising a main chain having a beta-1,3-glucopyranosyl group unit of formula I (wherein Glu is glucopyranosyl, and numerals refer to positions of bonding) as a repeating unit, and a second repeating unit of formula II (wherein Glu and numerals are as defined above, and m is 0-2) or both of this second repeating unit and a third repeating unit of formula III (wherein Glu and numerals are as defined above, and n is 0- 2) bonded to the main chain. This chemically modified polysaccharide has a remarkably low toxicity against mammals despite its very potent antineoplastic activity, so that it can be administered by hypodermic, intramuscular, or intraveneous injection or other conventional methods by dissolving or dispersing it in a physiologicaly acceptable base similar to well-known antineoplastic polysaccharides.

Title: Measuring method of sulfuric acid ion
Inventor: YOSHIMOTO MASABUMI
IPC: G01N30/06
Filed: 1991-09-26
Abstract: PURPOSE:To enable accurate measurement of concentration by a method wherein a gaseous sample containing a sulfur oxide is brought into contact with a water solution of a hydrogen peroxide, the concentration of the hydrogen peroxide is adjusted thereby to be a specific value and sulfuric ions in a liquid sample thus prepared are measured by an ion chromatography. CONSTITUTION:In a gaseous sample, sulfuric acid ions (SO4<2+>) are generated by oxidizing an sulfur oxide (SOx) in the sample by bringing the sample into contact with a water solution of a hydrogen peroxide. The concentration of the hydrogen peroxide of this sample liquid is selected to be 0.4wt.% or below, or 0.3wt.% preferably. When the concentration of the hydrogen peroxide exceeds 0.4wt.%, the shape of a peak of a sulfuric acid in an ion chromatograph changes and it is impossible to execute highly-precise measurement. Although it is unnecessary to make the liquid sample be absorbed in the water solution of the hydrogen peroxide, pH of the sample is adjusted to be 6 or above, or 7 to 11 preferably. By analyzing these sulfuric ions by an ion chromatography, the content (concentration) of the sulfur oxide in the gaseous sample or the sulfuric acid ions in the liquid sample can be measured accurately.

Title: Mos field effect transistor
Inventor: HONMA AKIRA
IPC: H01L29/78
Filed: 1983-12-30
Abstract: PURPOSE:To prevent a decline of threshold voltage even in case of short channel by providing a region of the same conductive type as a substrate and of higher impurity concentration than that of the substrate under source and drain regions. CONSTITUTION:Only in the part under a source region 14 and a drain region 15 of MOSFET, P<+> buried regions 16 and 17 of higher impurity than that of a P typ substrate 11 are formed. Consequently, even though a part of charges in a shoulder part B of a depletion layer is present under the drain region 15 or the souce region 14, a threshold voltage tends to increase because an electric line of force exists in a direction of a polysilicon gate 13. However, a level difference in the shoulder part B of the depletion layer is small so that variation of the threshold voltage is small. Also it is made possible to prevent the variation of the threshold voltage even in case of short channel by adjusting impurity concentrations and thicknesses of the buried layers 16 and 17.

Title: Alarm
Inventor: TAGO TOKUJI
IPC: G08B1/00
Filed: 1992-08-24
Abstract: PURPOSE:To transmit dangerous information via a medium that is odor by destroying an odor wrap by melting a fuse member by energizing when abnormality is detected. CONSTITUTION:When a sensor means 10 detects certain abnormality, a circuit means 20 is energized, and melting due to an overcurrent in a fuse means 21 is started. When the fuse means 21 is parted by melting, the lower end part 22 of the means is dropped, which destroys the odor wrap 30 located just underneath, and odor generating substance in the inside is spread in a container 31, then, the odor is diverged. Since a spring 23 and a weight 24 as drop pressing means are provided at the lower end part 22 of the fuse means 21, when the melting is started, the fuse part 21 is parted before it is completely melted, and the lower end part 22 is immediately dropped, and the odor wrap 30 is quickly destroyed, which accelerates the generation and diffusion of the odor. The odor wrap 30 is formed by wrapping liquid shape odor generating substance with film easy to destroy.
