Title: Safety net having russell-braided structure
Inventor: KAMIYA KUNIAKI
IPC: E04G21/32
Filed: 1994-03-04
Abstract: PURPOSE:To enhance the safety by arranging main meshes formed of a thick yarn for bearing the weight of a dropping one, and auxiliary meshes or small meshes formed of slidable twine yarns for inhibiting the dropping one from passing therethrough, in a single net. CONSTITUTION:Composite yarns 1 are Russell-braided so as to form main meshes 2, and twine yarns 3, 4 and the composite yarns 1 are Russell-braided so as to integrally unite them at braiding points 7, 8 so as to four auxiliary meshes 5. Then, the yarns 3, 4 are slidably and vertically superposed with one another in the centers of the main meshes 5 without being coupled together, and a rope 6 is threaded through the meshes around the net. The lengths L1, L2 of one side of the main and auxiliary meshes are set in the following relationship: 18cm <=L1<=26cm, and 9cm<=L2<= 13cm. Further, the tensile strengths Xkg, Ykg of the yarns 1, 3, 4 are set in the following relationship: X>=215-{(26-L1)X5.90}, Y>= 173--{(13-L2)X9.52}. Further, a synthetic resin process is carried out so as to prevent loosening or the like. Thereby it is possible to efficiently erect the net and to enhance the safety.

Title: Manufacture of multilayer circuit board
IPC: H05K3/38
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a method for manufacturing a multilayer circuit board in which adhesion defect of an inner layer circuit board and an adhesive insulating layer can be prevented and treating solution in the course of manufacturing scarcely remains on the boundary between the circuit board and the insulating layer. CONSTITUTION:When a copper foil of an inner layer circuit board is patterned to form an interconnection layer 1 and a plurality of the boards are laminated through an adhesive insulating layer to manufacture a multilayer circuit board, the foil is previously surface treated by using aqueous solution containing cupric sulfate and sodium chloride. Since the surface of the foil is roughed by this treatment, adhesive strength of the layer 1 formed of the foil and the surface of the layer 1 is formed of sole metal copper or metal copper covered with Cu2O to improve its acid resistance. Accordingly, even if the surface of the layer 1 is brought into contact with acid treating agent in the course of manufacturing the multilayer circuit board, it is not dissolved, and hence adhesion defect of the inner layer circuit board and the insulating layer can be prevented and treating solution in the course of manufacturing does not remain on their boundary, etc.

Title: Brush electrostatic charging device
Inventor: OKUNO TATSUO
IPC: G03G15/02
Filed: 1984-04-12
Abstract: PURPOSE:To dislocate toner entered into conductive fiber to a photosensitive body and prevent it from staying in the conductive fiber by rotating the photosensitive body for a specific time in the opposite direction of a normal rotating direction except in electrostatic charging operation. CONSTITUTION:The conductive fiber 9 implanted in a conductive substrate 8 contacts the photosensitive body 2 during copying operation while curved in the rotating direction of the photosensitive body 2 as shown in figure and a small quantity of residual toner B enters the conductive fiber 9. The photosensitive body 2 reverses as shown in a figure (b) after the copying operation and the conductive fiber 9 contacts the photosensitive body 2 while curved in the opposite direction, so said toner B is dislocated to the photosensitive body 2 to prevent the toner from staying in the conductive fiber 9. Consequently, even when a fixed flat type conductive brush is used, the residual toner on the photosensitive body 2 is prevented from staying in the conductive fiber and excellent electrostatic charging uniformity is maintained for a long period.

Abstract: PURPOSE:To stabilize time response by constituting a state feedback loop thereby braking the resonance characteristic occurring upon connection of an LC filter or an inductive load. CONSTITUTION:A difference  V between a set voltage Vx and an output voltage Vo is amplified through a proportional element(PE) 32 having gain (c) to produce a value c V. On the other hand, difference between a stack current X2 (filter input current) and a load current X4 is amplified through a PE 37 having gain K1 to produce a value, which is then added to the value c V to produce a value St=c'V-K1(X2-X4). The value St is then fed to a proportional integrating element 31 to produce a first voltage command value u1. Difference between the set voltage Vx passed through a PE 33 (gain f1) and the output voltage V0 passed through a PE 34 (gain f2) is added to the difference between the stack current X2 passed through a PE 35 (gain f31) and the load current X4 passed through a PE 36 (gain f32) to produce a second voltage command value u2. The values u1, u2 are then added to produce a voltage command signal for a single-phase inverter 1.

IPC: G03G9/13
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic liquid developer excellent in stability with time with which a high system rate is obtd., by incorporating an oil-soluble ionic surfactant as a charge controlling agent and incorporating a specified polyester resin as a binder resin into color fine particles. SOLUTION: This electrophotographic liquid developer is produced by dispersing color fine particles in an electrically insulating liquid medium, into which an oil-soluble ionic surfactant is incorporated as a charge controlling agent. The color fine particles contain a polyester resin having the acid value between >=40 mgKOH/g and <=100 mgKOH/g as a binder resin. The acid value is measured under conditions according to JIS K5400. Since a polyester resin having a rather high acid value as >=40 mgKOH/g and <=100 mgKOH/g is used as the binder resin for the toner in a preferable state of the electrophotographic liquid developer, large charges of the toner particles can be obtd. and the developing rate can be increased.

Abstract: PURPOSE:To improve the surface state after soldering without damaging the  basic capacity as a solder material, by adding small quantities of Si, Pb, Mg,  etc. to an Ag-Cu alloy and adding Ge, Mn, Ni, etc. to it furthermore. CONSTITUTION:0.05-0.5% one or more out of Si, Pb, and Mg are added to the Ag-Cu alloy consisting of 50-95% Ag and 5-50% Cu, and further, 0.005-1% one or more of Ge, Mn, and Ni are added to this Ag-Cu alloy, thus obtaining a silver solder. Si, Pb, and Mg are metal elements easy to combine with oxygen and deoxidize the silver solder in the course of production and use of the silver solder and prevent the soldering surface from being rough by gas discharge when the silver solder is solidified. Ge, Mn, and Ni make the metallic organization minute for solidification of the silver solder to make the surface smooth. The soldering strength of this silver solder is approximately equivalent to that of the conventional soldering material in respect to the basic capacity, and the spread area is reduced slightly but it is not a problem in the practical use.
