Title: File retrieval system and file holding server
Inventor: SENDA KOICHI
IPC: G06F17/30
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a server-client type file retrieval system and a file holding server to quickly transfer a file to a client. SOLUTION: A client C refers to the file information FI and transfers a file to a server FS which is holding a text file. The information FI comprises an identification code which identifies whether the file held by the server FS is identical to a text file or a duplicate file and an existing server name of the file and then the FI is held by the server FS in every file. The server FS holding the text file manages the item of the file server name included in the information FI after rewriting it into the server name that referred to the file every time the FS is referred to. The server FS holding the duplicate file transfers the identification code showing a duplicate file and an existing server name of the text file after adding them to file against a file transfer request and then the FS deletes its own file and the file information.

Title: Overcurrent protecting circuit of gate turn-off thyristor
Inventor: ISHIDOU MICHIHARU
IPC: H02M1/06
Filed: 1983-11-29
Abstract: PURPOSE:To protect a GTO thyristor against an overcurrent without reducing the capacity of an element by improving the breaking capacity of a gate turn- OFF (GTO) thyristor by temporarily increasing the capacity of a snubber capacitor. CONSTITUTION:When an overcurrent starts flowing a GTO thyristor 1, a detection signal from an overcurrent detector is supplied to the first and second signal generators 8, 9. When the second generator generates a turn ON signal of the thyristor by the detection signal, a thyristor 7 turns ON, and the thyristor 7 and a capacitor 4 are electrically connected in parallel with the thyristor 1. Thus, the snubber circuit of the thyristor 1 becomes the state connected in parallel with the first and second snubber circuits 11, 12 at the overcurrent detection time, the capacity of the capacitor increases to improve the gate breaking withstand voltage of the thyristor 1.

Abstract: PURPOSE:To improve cutting conditions and prolong the life of a cemented carbide end mill by coating the body surface of the end mill made of cemented carbide with TiCN and/or TiN of 0.5-5mum at a temperature of 700-900 deg.C by using CVD method and applying a cutting edge honing of 0.01-0.04mm. CONSTITUTION:A cemented carbide alloy material is machined so as to be formed a two-flute end mill of 10mm in diameter and 30 deg. in helix angle, applied honing by brush sticks, and coated with TiN and/or TiCN. In this coating process, using CVD method, organic CN compound, titanium tetrachloride, and hydrogen are made to react at a temperature of 700-900 deg.C for preventing itself from decarbonizing and coarsening, resulting in forming a film thickness of 0.5-5mum suitable for wear and flaking resistances. A cutting edge is honed by 0.01-0.04mm to reduce cutting resistance and prevent blades from breaking. In the case of cutting under such cutting conditions as a feed rate: 50m/min., feed per blade: 0.03mm, a cutting depth: 10mm, cutting width: 1mm, workpiece material: SCM440, cutting length: 5m, and cutting edge honing: 0.02mm, the result is shown in the list.

The resultant concentrate is redissolved in water and subjected to reversed phase liquid chromatography. When water is passed as a mobile phase, only a fraction which is not held is recovered to afford the aimed safflower extract having a main peak at k'=0.5-6 when measured by high-speed liquid chromatography under conditions as follows; Column; ODS (5mu) 4phiX250mm. Mobile phase; acetic acid/acetonitrile/water=0.1/1/98.9. RI or UV (254nm). In the above-mentioned purification step, dyestuff components, blood platelet agglutination inhibitory components and and blood coagulation inhibitory components can be removed and the vasodilator action can be remarkably improved at the same time.
