A method for forming a continuous material by connecting sheet materials which are used in various fields including the processing of metal foils, the processing of metal-plastic composite film material, and the processing of thermoplastic resin films such as polyimides, and an apparatus used for carrying out this method comprising a hot press, a material locking device and an accumulator. A continuous material can be formed by interposing a resin bonding layer between the trailing edge of a sheet material and the leading edge of another sheet material, and subjecting this part to thermocompression bonding.

Method for forming a continuous material

An insulating adhesive tape which comprises a base supporting film and an adhesive layer formed on at least one surface thereof, said adhesive layer being formed of a thermoplastic polymer comprising a thermoplastic polyimide, wherein said thermoplastic polymer has a glass transition temperature ranging from 180.degree. C. to 280.degree. C. and an elastic modulus ranging from 10.sup.10 dyne/cm.sup.2 to 10.sup.11 dyne/cm.sup.2 at 25.degree. C., said modulus including a value ranging from 10.sup.2 dyne/cm.sup.2 to 10.sup.9 dyne/cm.sup.2 at a temperature between 250.degree. C. and 300.degree. C.

Ferromagnetic metal particles and preparation process thereof

An automatic analytical apparatus in which a series of operations ranging from the sampling into a treating receptacle, pretreatment, analysis and discharge of a fluid sample to the preparation for the next analysis are repeated automatically in order, wherein the time-dependent variation of the composition is traced successively. This permits the presence of the composition variation or the course of the composition variation to be confirmed or the composition variation to be controlled, automatically.

Method and apparatus for automatic analysis of fluid composition

Disclosed herein is a process for producing ferromagnetic iron powder, which process comprises adding and mixing boron oxide or a borate with .alpha.-FeOOH or .alpha.-Fe.sub.2 O.sub.3 without dissolving the former, heating the thus-obtained mixture to 350.degree. C. or higher in a non-reducing atmosphere and then reducing the thus-heated mixture.
