Title: Method of and apparatus for automatically controlling tension in winding wire or the like
Inventor: HARASHIMA TOMOO
IPC: B65H59/38
Filed: 1978-08-03
Abstract: PURPOSE: To provide a wire winding system, in which wire or the like can be wound around a bobbin under a constant tension, with no use of a touch roller that is held in contact with the wire, whereby it is enabled to protect wire coatings from damages in winding the wire around the bobbin.  
     CONSTITUTION: When motor 2 is started and bobbin 1 is turned via electromagnetic clutch 3, wire or the like W is wound around bobbin 1 after being passed around a swing roller 4 at the top of arm 5 which is arranged to be capable of turning pivotally around a pin. The arm 5 is swung in response to the tension of wire W for achieving on-off control of switch S. As the wire W is wound around bobbin 1 and its diameter is increased, tension of wire W is lowered and arm 5 is turned in clockwise direction, thereby turning ON switch S. Thereupon, high voltage E 1  is applied to CR circuit and base voltage of transistor T is raised gradually. This causes gradual increase of current afforded to electromagnetic clutch 3, so that wire winding tension is increased correspondingly.

Title: Film forming apparatus
Inventor: KURIHARA NORIKO
IPC: C23C16/50
Filed: 1986-04-25
Abstract: PURPOSE:To prevent a film from depositing on the microwave introducing window of a plasma generator by placing a nozzle on the plasma blowoff side of the generator and feeding a film forming gas to the vicinity of the inflow whole of the nozzle so as to prevent the film forming gas from flowing backward. CONSTITUTION:A nozzle 3 is placed on the plasma blowoff hole 2 side of a plasma generator 1 and a film forming gas is fed to the vicinity of the inflow hole 3a of the nozzle 3. The fed film forming gas is activated by contact with plasma and the activated gas is immediately transferred to the downstream side through the nozzle 3. Even when the spouted film forming gas is dispersed on the downstream side, the strong flow in the nozzle 3 prevents the gas from flowing backward. Accordingly, a film is prevented from depositing on the microwave introducing window 4 of the plasma generator 1 and continuous film formation can be carried out for a long time.

Abstract: PROBLEM TO BE SOLVED: To set a measurement area according to a range-found object which moves in a picture plane with simple device constitution and a small arithmetic processing quantity by setting the measurement area with a moving body image signal found from variation of an image in a time-base direction. SOLUTION: A solid-state image pickup device 13 for movement detection outputs the image signal and moving body image signal found from the variation of the image in the time-base direction. A high-pass filter 16 extracts a high-frequency component of spatial frequency from the inputted image signal and supplies it to a gate circuit 17. A gate control part 19 delays the inputted moving body image signal by a specific delay time to put the image signal of the input stage of the gate circuit 17 and the moving body image signal in phase with each other. The gate control part 19 outputs this moving body image signal to the gate circuit 17 as a gate timing signal as it is. The gate circuit 17 extracts the image signal according to the gate timing signal and selectively extracts the image signal in the range corresponding to a moving body area.

Title: Production of fine colloid particle or magnetic fluid
Inventor: NAKATANI ISAO
IPC: H01F1/44
Filed: 1990-04-12
Abstract: PURPOSE:To provide a reaction product having uniform particle diameters and excellent dispersion by effecting the reaction of a metal carbonyl with a nitrogen compound in two specified steps in producing a colloid of fine metal nitride particles or a magnetic fluid of metal nitride. CONSTITUTION:A metal carbonyl (e.g. iron carbonyl) is reacted with a nitrogen compound (e.g. ammonia) in a solvent preferably in the presence of a surface active agent at a relatively low temperature to produce a precursor comprising a nitroge-containg metal carbonyl compound [e.g. Fe2(CO)6(NH2)2]. The reaction temperature is then raised to decompose the precursor into fine particles of a metal nitride (e.g. iron nitride), thus producing a colloid of fine metal nitride particles or a magnetic fluid of metal nitride. In this technique, a by-product such as Fe(CO)5 will not be produced; therefore, no reduction in the yield of an objective material due to the formation of noncrystalline iron originating in the by-product will not occur.

A quantity of valve lift of the suction valve 13 can be made large, through which an improvement in volume efficiency can be contrived. Then, in an exhaust stroke, burnt gas in the inside of the combustion chamber 10 is discharged from an exhaust valve port 12 through opening of a pair of exhaust valves 14. In this instance, the burnt gas flows to the top of the center of the combustion chamber 10 from the fringe part of the combustion chamber 10, discharged to an exhaust port 2 effectively and evenly and uneven gas pressure is not generated within the combustion chamber 10.
