IPC: G11B20/02
Filed: 1991-01-11
Abstract: PURPOSE:To enable a cost down compared with a conventional constitution, and to improve a reliability without separately providing a circuit which delays an input signal, so that a signal to which an emphasis characteristic is not applied can be obtained. CONSTITUTION:When an emphasis processing is operated to an input signal(MUSE signal), the input signal passing through a delay circuit 1(DLn) is multiplied by a coefficient by a multiplier 3(MULn), and inputted to an adder 7. On the other hand, the output signal of an adder 5 is inputted through a switch 6 to the adder 7, and added to the output signal of the multiplier 3 by the adder 7, so that the signal to which the emphasis characteristic is applied can be obtained. When the emphasis processing is not operated to the input signal, the input signal passing through the delay circuit 1(DLn) is multiplied by the coefficient by a multiplier 4, inputted through the switch 6 to the adder 7, added to the output signal of the multiplier 3(MULn) by the adder 7, so that the signal which is delayed by an (n) clock to the input signal (to which the emphasis characteristic is not applied) can be obtained.

Abstract: PURPOSE: To treat a large quantity of a liquid at low cost without heating and by using a simple device by a method wherein cavitation is generated in a negative pressure atmosphere when separating a gas dissolving in the liquid.  
     CONSTITUTION: When a piston 2 is slid at a fixed expansion speed E and a cavitation chamber 4 is expanded, a liquid, which flows from a suction pipe 7 and dissolves a gas, flows into the cavitation chamber 4 as a jet accompanied by violet turbulence, and cavitation 14 is generated in a negative pressure atmosphere. Infinitestimal bubbles functioning as nuclei grow to minute bubbles 15, and collect to a ceiling surface 16, and a large bubble 17 is produced. When the piston 2 is slid at a small contraction speed F, the large bubble 17 may be discharged by opening a valve 18 of a gas discharge pipe 12 because the large bubble 17 flows out through a discharge hole 9 and is stored in a gas storage portion 11.

Abstract: PURPOSE:To prevent a constituent material from being diffused mutually between conductive regions formed at the upper layer and the lower layer by installing the following in an opening part formed in an interlayer insulating film: a barrier layer used to prevent the constituent material from being diffused mutually between an electrode which electrically connects the conductive regions at the upper layer and the lower layer and the conductive region in the lower layer. CONSTITUTION:A lower-layer TiSi2 film is nitrified at the bottom of contact holes 17A to 17F in required parts of an insulating film 17; a titanium nitride film 23 is formed. An electrode 24 composed of WSi2 is filled on it so as to be a level nearly equal to the insulating film 17.

Title: Method and apparatus for manufacturing welded tube
Inventor: ITAYA MOTOAKI
IPC: B21C37/00

Abstract: PURPOSE:To reduce the number of forming stands and to shorten the set-up time by heating all the circumference in the lengthwise direction of a stock tube right after welding and giving tension from the downstream side at a speed higher than the welding speed to be deformed plastically. CONSTITUTION:The stock tube 2 welded by a squeeze roll 14 is passed through a grip roll 4 and heated by an induction heating coil 5. Here, a sizing roll 15 on the downstream side is driven so that the speed of the passing tube is larger than the welding speed and a suitable tension is given to the stock tube 2 between the grip roll 4 and the sizing roll. Accordingly, since the heated part of the stock tube 2 is smaller in deformation resistance than other parts, it is deformed drastically and drawn in both outer diameter and wall thickness. The deformed stock tube 2 is cooled by cold air from a cooling nozzle 6 down to the neighborhood of the room temperature free from deformation, and then, a light rolling reduction is given by a sizing roll 15 and a product 3 having a desired outer diameter is finished.
