Patent JP-H09226075-A (JP)
Title: Manufacture of multilayer pipe
Inventor: MIDORIKAWA KATSUO
IPC: B29C48/34
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To reduce a raw material cost, inhibit toxicity, prevent chloride of lime from sticking to the inner face of a pipe, facilitate an engagement from a viewpoint of installation and make it easy to perform the extrusion molding of the pipe by forming a laminated pipe consisting of a combination of a crosslinked polyethylene pipe and a homogeneous crude polyethylene pipe and arranging the crude polyethylene pipe on the internal face part. SOLUTION: Crude polyethylene is extruded in a molten state from an extrusion machine to form a cylindrical C2, and a crosslinked polyethylene is likewiss melt extruded from another extrusion machine, In addition, the cylindrical C2 is discharged from a molding die in such a manner that the cylindrical C2 is encircled with the crosslinked polyethylene on the cylindrical C2 in a confluent part. Consequently, an interface C3 is formed between the inner face C1 of crude polyethylene and the outer face C2 of crosslinked polyethylene. In this case, however, the interface C3 is not clearly defined. Thus the raw material is less costly, and a silane compounding agent and a tin compounding agent as crosslinking agents do not bleed internally, so that this pipe does not cause a toxicity hazard.  Besides, it is possible to blend the crude polyethylene with a chlorine separation inhibitor such as an antioxidant as a chloride of lime inhibitor or an ultraviolet absorbent.

Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a high definition display of vertical resolusion with different systems at a low cost by constituting shift registers in the vertical direction with plural series which are operatable independently. SOLUTION: Shift registers 1-4 connected with selection signal lines for every four rows are driven by clock signals whose phases are different by 360/4=90 degrees. At this time, respective selection signal lines are selected with the time of four times of a horizontal scanning period. In other word, the lines are selected over four times in one frame. However, since there is the phase difference of 90 degrees between upper and lower rows, the resolution of this display is never impaired. Moreover, at the time of displaying a VGA noninterlaced driving having 480 lines of scanning lines, a display can be performed while using the number of pixels of the vertical direction equivalent to 960 lines by shifting phases of shift registers 1-2 whose phases are matched and shift registers 3-4 whose phase are matched by 180 degrees and by driving selection signal lines simultaneously.

Title: First aid adhesive plaster
Inventor: NOMURA TAKUYA
IPC: C09J7/02
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce curling and stimulation to the skin when separating and prevent an adhesive from remaining on a skin surface by using a polyolefin film as a base material and specifying flexural rigidity of the base material. SOLUTION: A base material of flexural rigidity between 0.01 g.cm and 0.25 g.cm is formed using a polyolefin film. A first-aid adhesive plaster is formed of this base material. The polyolefin film is formed into a double layer or triple layer structure, using an ionomer, a low density polyethylene, an intermediate density polyethylene, a high density polyethylene or the like. A variety of strength controllers, an extending agent such as an inorganic powder or the like, and a dye/pigment may be mixed into the sheet. The film may be uniaxially oriented, biaxially oriented, or non-oriented. True flexural rigidity less than a specified value makes pasting to a skin difficult and too high flexural rigidity increases stimulation to the skin and causes curling. Thus stimulation, curling or the like can be prevented.
