Abstract: PURPOSE:To obtain a humidity sensor excellent in response and durability, by providing a humidity sensitive layer wherein sublimable org. coloring matter low in the resistance value by moisture absorption is diffused and penetrated into hygroscopic resin having a softening point near to the sublimation point of said coloring matter on an insulating substrate having a detection electrode formed thereto. CONSTITUTION:A resin layer 3 having a softening point near to the sublimation point of sublimable org. coloring matter lowered in the resistance value thereof by moisture absorption is formed onto an insulating substrate 1 comprising Al2O3 so as to cover the surface of the substrate 1 having comb shaped electrodes 2, 2 formed thereon from thermoplastic hygroscopic resin having a group such as OH, COOH or CONH, for example, polyester resin or nylon resin. In the next step, the alcohol solution of the aforementioned sublimable org. coloring matter 5, for example, rhodamine B or malachite green is applied to art paper 4 and, after drying, the coating surface of the coloring matter 5 thereon is superposed to the layer 3 while heating is performed from the side of the art paper 4 under pressure to penetrate the coloring matter 5 into the periphery of the electrodes 2 in the layer 3 and to precipitate the same thereto. By this method, a sensor free from the solidification and the effluence of the coloring matter even under high humidity, especially under a dew condensed state and excellent in responsiveness is obtained.

Title: Liquid flowing-out device for strengthening fire resistant performance of heat insulating material and the like
Inventor: KITAMURA OSAMU
IPC: E04B1/94
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To lengthen fire resistant time of a heat insulating material at disaster stricken time by a fire by oozing out chemicals such as water at disaster-stricken/temperature rise time without using a motive power source. SOLUTION: A fire extinguishing liquid preserving vessel 1 is arranged in the vicinity of a heat insulating material 3 to thereby insert a pipe 6 passing through a thermosensible actuating valve 2 into the heat insulating material 3. An air hole 8 is arranged in the fire extinguishing liquid preserving vessel 1 so that a thermosensible actuating valve 9 is also attached to this. Operation detecting holes 5 are arranged in an outer shell 7 of the heat insulating material. When an ambient temperature of the heat insulating material 3 rises by a fire, the thermosensible actuating valve 2 and the thermosensible actuating valve 9 are opened so that liquid of the fire extinguishing liquid preserving vessel 1 wets the heat insulating material 3 through the pipe 6.  Afterwards, a fire extinguishing liquid oozing out to the periphery of the operation detecting holes 5 leaves a oozing-out trace. At this time, the oozing out trace can be more clearly confirmed when a colored fire extinguishing liquid is used. The two thermosensible actuating valves may be actuated by the same thermosensible actuating device. Thus, the fire resistant time can be lengthened by an evapotranspiration quantity of water.

Title: Spindle fitting device of rotary grinding wheel
Inventor: SASAKURA SHIZUKI
IPC: B24B45/00
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To easily and surely fix a rotary grinding wheel on a spindle by providing a fastening means for fastening an elastic body in the axial direction so that the elastic body is pressed to the inner periphery of the rotary grinding wheel side and the outer periphery of the spindle side, respectively. SOLUTION: A fastening screw 25 of each grinding wheel pressing plate 13 is fastened for preset torque or screw-in amount. Whereupon, an elastic body 12 is expanded in the direction of inside diameter and in the direction of outside diameter by fastening the fastening screw 25 so that a fitting clearance between a rotary grinding wheel 11 and the elastic body 12, a fitting clearance between the large diameter shaft part 14 of a spindle 10 and the elastic body 12 is eliminated to press the elastic body 12 to the rotary grinding wheel 11 and the large-diameter shaft part 14 of the spindle 10. Accordingly, the clearance between the rotary grinding wheel 11 and the spindle 10 is blocked up by the elastic body 12 so that the rotary grinding wheel 11 and the spindle 10 are fixed to each other without clearance. Though the inside diameter side of the rotary grinding wheel 11 is centrifugal-expanded by centrifugal force, the elastic body 12 is elastically deformed to prevent generation of clearance.
