PURPOSE:To make it possible to stabilize the ground early with a lot of window holes to the peripheral surface of top type block and draining water from the top type block. CONSTITUTION:A top type block 10 for the ground stabilization is formed by filling the permeable agent 18 into a top type enclosure 16 having a lot of window holes 17 and hardening it. A conic drum body 11 is provided to the lower part of the flat upper board 12, and a cylindrical axis foot 13 is provided to the lower center of the drum body 11. A combined reinforcing bar 15 is inserted into the top type enclosure 16 so as to pass through the center of the drum body 11 and the axis foot 13, and the main part of the combined reinforcing bar 15 is buried into the hardened permeable agent 18. The upper end bending section 15a of the combined reinforcing bar 15 is projected from the flat upper board 12 of the top-like block 10.

An interior wall coating coil with air purification and humidity regulation functions is mainly prepared from natural plant fiber, mineral fiber and kieselguhr in a heat bonding mode, VOC pollutants generated by traditional interior wall coatings, emulsion paint and wallpaper are avoided, the decoration function of traditional interior wall coatings, emulsion paint and wallpaper is achieved, and the natural and environment-friendly properties of walls are kept. The interior wall coating coil can be directly pasted on the surfaces of cement walls, gypsum boards, wood boards and the like to replace interior wall coatings, emulsion paint, wallpaper and the like, and the defect of construction complexity of traditional interior wall coatings is overcome. According to a preparation method, calendaring is directly performed in a powdery state, and it is guaranteed that the interior wall coating coil has through pore structures and is excellent in adsorption performance; a decomposing agent can effectively degrade formaldehyde, benzene, ammonia and other pollutants in air, and thus the purpose of air purification is achieved; besides, the interior wall coating roll can automatically regulate the relative air humidity with the moisture absorption and release performance.

PURPOSE:To protect an overcurrent with a simple circuit and to reduce the cost of said protection by detecting indirectly an overcurrent state produced by the stabilized output by the voltage rise of the non-stabilized output and stopping the stabilizing action. CONSTITUTION:When a stabilized output current I0 increases, the stabilized output voltage V0 maintains a fixed level by a stabilizing action. While the non-stabilized output voltage V0 increases in proportional to a current. Therefore the action point voltage Vocp is set at a voltage detecting circuit 99 to an overcurrent working point current Iocp. Thus a fact that the non-stabilized output voltage reaches the voltage Vocp, and the actuation of a switching transistor Tr46 is discontinued. Then the overcurrent can be protected. In other words, a constant voltage diode 100 conducts when the output voltage exceeds the Vocp and an LED104 emits light by the current of the diode 100. As a result, a photothyristor 74 conducts and the base current of the Tr64 is absorbed by the thyristor 74. Then the actuation of the Tr64 is stopped to release the switching action of the Tr46.

PURPOSE:A resol type phenolic resin powder suitable for the production of paper/phenol laminated sheets by the resin-loaded paper making process, having specified physical properties and a specified ammonia content. CONSTITUTION:A resol type phenolic resin powder prepared by reacting a phenol (e.g., phenol) with a formaldehyde (e.g., formalin) at about 50-120 deg.C in the presence of ammonia or its derivative (e.g., hexamethylenetetramine), and having a nitrogen content of 3.3-5%, a gel time of 120-300sec and a fluidity of 150- 230mm.. A resin-loaded wet sheet prepared from the above resin does not undergo a curing reaction of resin when it is dried at temperatures as high as about 100 deg.C in order to remove the moisture; exhibits good resin flow when it is heated under pressure in the final step; and can provided laminated sheets excellent in electrical and mechanical properties, etc., within a short drying time.
