Title: Die for forming shadow mask
Inventor: TANSHIN MASAYA
IPC: H01J9/14
Filed: 1987-12-21
Abstract: PURPOSE:To reduce the amount of a spring back and its amount of fluctuation and to form a mask which does not engage with a punch by providing a tapered part in which a clearance between a punch and a die changes gradually inside the die or outside the punch. CONSTITUTION:A flat mask put between the die 12 and a blank holder 14 is overhung by lowering the punch to form a main curved surface part 15. The punch 11 is lowered further to form a side wall part 16 by a clearance provided between the punch 11 and the die 12. The clearance is fanwise in a downward direction. When the punch 11 rises and comes out of the die 12, since the die 12 is provided with a tapered part 17, a strong frictional force is generated between the side wall part 16 and the die 12 and the die 12 clings to a shadow mask 15. The punch 11 comes out smoothly and the shadow mask 15 does not deform. When the punch 11 rises to the full, the shadow mask 15 can be taken by a pad 13 uniformly out of the die 12.

Title: Control valve
Inventor: KAGAWA TOSHIHARU
IPC: F15D1/02
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To reduce gas circulation noise in a high-pressure and great-flow-rate gas circuit. SOLUTION: A valve 12 with a variable width of slit is formed by alternately laminating annular discs 18 and elastic spacers 19, and the width of the slit in the valve 12 is controlled by a pilot pressure control means. Primary side pressure gas is discharged from a center hole CH in the valve 12 through a lit SR to the secondary side. The pressure gas is radiated from the valve 12 to all peripheral direction as a sectionally linear laminar flow by the rectifying effect of the slit SR, so that vortex and disturbance resulting in a flow to be stirred are extremely reduced and noise given from gas when passed through the valve is restricted.

Title: Paste for wallpaper
Inventor: AMANO YOSHIHIRO
IPC: C09J103/00
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a paste which does not impair the surface of an adherend, has excellent adhesiveness and used only for wallpaper whose bonding surface is a fireproof gypsum board. SOLUTION: This paste 2 is prepared by adding a synthetic starch paste, mica and methylhydroxyethylcellulose to water. This can show strippability (releasability) owing to the cleavability of mica and sufficient adhesiveness owing to the synthetic starch paste. The methylhydroxyethylcellulose added performs e.g. the modification of the kneadability of the mica and the synthetic starch paste, and therefore the paste has high adhesiveness as a whole and is adapted so that the layer of the paste itself may be separated when the wall paper is released.

Abstract: PURPOSE:To minimize power interruption time and area by immediately deciding a faulty section by means of a photocurrent sensor fixed to a bus supporting insulator or a disconnector supporting insulator upon occurrence of a fault in a distributing substation provided with a plurality of transformers. CONSTITUTION:When a fault occurs at position F1 in section A of bus section, i.e., on the bus between a bus section disconnector 12 and a photocurrent sensor 14, output from a current transformer 8 at a power receiving section 1 has a phase different from that of an output from the photocurrent sensor 14 for sectioning sections A and B, and thereby a detector 22 detects a fault in section A. At that time, a faulty section decision unit 23 can decides that both sections A and B are faulty. When bus section disconnectors 12, 13 are opened to isolate faulty section and power is received only at a power receiving section 2, power distribution to a sound section C can immediately be resumed while avoiding voltage application to the faulty section B.
