Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent separation and omission of a sheet from being generated even by allowing to stand in an ambient of much moisture for a long period of time by simplifying sticking operation of the sheet by a method wherein a liquid absorptive sheet contains a support base material of liquid absorptive polymer and a pressure- sensitive adhesive, and through dried after being swollen by absorbing once liquid, its swollen form is held. SOLUTION: To a monomer capable of being converted to a liquid absorptive polymer with polymerization having acrylic acid or acrylate or the like as main constituent, a pressure sensitive adhesive of acrylate or the like and a cross-linking component of a compound having two or more isocyanato groups capable of reacting on both are added on a base material of sponge-like porous material such as hydrophilic fiber of wood pulp, cotton, etc., or hydrophobic fiber of polyester, acrylate, etc., woven fabric and nonwoven fabric of metal fiber, shape memory metal fiber, etc. They are polymerized on the base material to obtain an absorptive sheet.  Consequently, the liquid absorptive sheet wherein it is excellent in liquid absorption swelling property, durability, easiness for manufacture, sticking operation in execution is simple, and though swollen by absorbing liquid, separation is not generated between the pressure sensitive adhesive layer and liquid absorptive polymer, can be prepared.

Filed: 1983-04-12
Abstract: PURPOSE:To prevent generation of quenching crack around a through-hole in the stage of hardening a material which has a through-hole and is going to be hardened by high frequency induction heating by inserting preliminarily a round bar having excellent heat conductivity in the through-hole. CONSTITUTION:Hardening of the screw part 1a of a spindle 1 is accomplished by subjecting said part to high frequency induction heating by a high frequency induction heating coil 3 while moving the coil and a nozzle 4 for injecting a cooling liquid to the outside of the part 1a then spraying cooling water to said part from the nozzle 4. If a pin hole 2 is punched in the part 1a, induction current concentrates in this part and heats the part to a considerably high temp. to generate a quenching crack in the stage of hardening and therefore a round copper bar 5 having excellent heat conductivity is inserted into the hole 2 so as to act as a chiller. The circumference of the hole 2 is prevented from being heated up to a particularly high temp. and the generation of quenching crack is thus prevented.

IPC: H01P5/12
Filed: 1982-04-20
Abstract: PURPOSE:To attain miniaturization and to excite even millimeter waves easily, by inserting a tapered metallic plate at the center of a square waveguide axially and using a power distributor taking one end of the square waveguide as two openings. CONSTITUTION:A polarized wave as shown in figure is excited by using an H plane magic T5 and taking an SUM terminal 2 as an input terminal, and a polarized wave shown in figure down right is excited by taking an EL terminal 4 of the H plane magic T5 as an input terminal. A polarized wave shown in figure middle right is excited by feeding power from one guide wall of a square waveguide A14. Since the A14 is an over size waveguide, the excellent characteristics are obtained by feeding power in phase from the opposing guide walls as required and taking one waveguide as a resistive terminator. Further, the cut- off frequency of the harmonic mode wave is increased, by taking countermeasures such as crossed inner shape of the A14 as required. Thus, the polarized waves shown in figure middle right are excited.
