Title: 2',3'-dideoxy-2',3'-didehydro-2'-fluoronucleoside and its production
Inventor: ROOMAN ZETSUTO SUTARUKII
IPC: A61K31/7064
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain a new compound having antiviral activity and useful as a treating agent for human immunodeficiency virus infection. SOLUTION: A compound is expressed by formula I [B is a purine base (adenine is excluded), an azapurine base, a pyrimidine base, etc.; R is H, azido, cyano, etc.], e.g. 2',3'-dideoxy-2',3'-didehydro-2'-fluorothymidine. The compound is obtained as shown below. At first, 2'-deoxy-2'-fluoroarahinonucleoside is made to react with a hydroxy-protecting group agent such as monomethoxytrityl chloride to selectively protect 4'-hydroxymethyl group. Subsequently, 3'hydroxyl group of the obtained intermediate is converted into a 3'-O leaving substituent to obtain an intermediate such as a compound of formula II (MMT is monomethoxytrityl; Mes is methanesulphonyl; R is H or CH3 ) followed by forming a 3',2-anhydro bond. Further, a double bond is formed between 2'-position and 3'-position of the 5-membered ring of the intermediate.  Finally, the protecting group is removed from the obtained intermediate such as a compound of formula III.

Title: Manufacture of tray for electronic component
Inventor: MINOWA FUMIO
IPC: H01L21/673
Filed: 1990-01-19
Abstract: PURPOSE:To easily and automatically insert a lead wire of an electronic component, to surely fix the electronic component and to make a manufacturing operation easy by a method wherein a plurality of holes are made at prescribed intervals in the lengthwise direction of a belt-shaped thin sheet and tube bodies are inserted into the respective holes and are fixed. CONSTITUTION:A plurality of holes 22 along the width direction of a belt-shaped thin sheet 20 are made at prescribed intervals in the edge on one side along the lengthwise direction of the belt-shaped thin sheet 2D; tube bodies 23 whose outside diameter is nearly equal to the inside diameter of the holes 22 are inserted into the respective holes and are fixed. Consequently, since only the belt-shaped thin sheet 20 is adopted as a constitution member and a belt-shaped annexing sheet as in conventional methods is not used at all, the number of components can be reduced and a productivity can be enhanced. Even when many pieces are laminated in the thickness direction, the pitch to an adjacent tray of round holes becomes accurate. Thereby, lead wires of an electronic component can be inserted easily at an automated apparatus. Since the large-diameter holes 22 are round holes, no gap is produced between the lead wires and the large-diameter holes 22 when the lead wires are inserted. As a result, the electronic component can be fixed surely.

Title: Block of bio-ethanol's semi-dry congruent dehydration apparatus for regeneration of adsorbent granules.
Inventor: BRĒMERS Gunārs
IPC: B01J29/00
Filed: 2011-05-16
Abstract: A regenerator of the pipe grid water adsorbent granules is provided for the restoration of the working efficiency of the used granules, which is necessary when a congruent dehydration technology of bio-ethanol is applied. In any place of the regenerator its pipes, collectors, inlets and outlets are arranged in a slanting position exceeding the angle of natural falling of the granules. This ensures continuous, reliable pouring of the granules inside the equipment and active heat exchange. The pipe grids can be completed in a number of ways, forming a variety of flows and chambers of different levels so adjusting the regenerator efficiency to the efficiency of the bio-ethanol dehydration unit. Water separation from the granules proceeds in a thermal way by introducing flue gases into the bottom chamber from the furnace which afterwards flows through all the chambers. The water in vaporous state is removed from the equipment trough the heat outlets provided on the level of each chamber. Cambers are separated from each other by shelves that change the direction of the flue gas flow.
