Filed: 1994-04-22
Abstract: PURPOSE:To provide a method in which the insulation degradation degree of a high- voltage power cable can be diagnosed during the operation of a live wire without using a power supply for measurement.

On the basis of four actually measured voltage values obtained as a result, an electromotive current capability at an equivalent central noise frequency by an insulator for the cable 2 as the object to be measured is computed, and the insulation degradation degree of the cable 2 is judged on the basis of the magnitude of the electromotive current capability.

Title: Ink supply device in printer
Inventor: NAWATE SHIGEO
IPC: B41F31/04
Filed: 1986-04-16
Abstract: PURPOSE:To enhance a supply ink adjusting performance an operating properties, by a method wherein each divided piece of a blade is made of a shape memory alloy and a blade control mechanism controlling individually the contact and space of the divided pieces with respect to an ink fountain roller is provided. CONSTITUTION:While not in operation, a periphery of an ink fountain roller 1 is pressurized to eliminate a space 4 so that the tip end of each divided piece of shape memory alloy 13 of a blade prevents an ink (a) from flowing out. During operation, the each divided piece of shape memory alloy 13 is heated and deformed due to a current-passing by each current-passing controller 17 so as to tend to return to the condition being previously stored under a temperature ranging from a deformation start point As to a finish point Af. Thus, the each divided piece 13 can be adjusted so as to freely establish the space 4 by being maintained at an appropriate temperature, whereby an ink can be supplied by the amount corresponding to the space. In addition, since the divided pieces of shape memory alloy 13 are made to be individually thermally deformed so that the blade can perform free adjustment of an amount of ink to be fed toward a roll shaft, thermal deformation of the each divided piece enables a space adjustment to be freely, rapidly, and finely conducted to remarkably enhance a supply ink adjusting performance and operating properties.

Filed: 1987-04-08
Abstract: PURPOSE:To obtain a high-resolution two-axial inclinometer which has an expanded measured angle range and good linearity by separating inclinometer outputs independently without any axial interference due to tilt angles in an X-axial and a Y-axial direction. CONSTITUTION:This device consists of an adder 3-1 and a subtracter 4-1 which are provided on the output sides of inclinometers 1 and 2 arranged in the orthogonal X- and Y-axial directions on the same plane and input the output signals of the inclinometers 1 and 2, function circuits 6-1 and 6-2 which convert the outputs of the adder 3-1 and subtracter 4-1 into reverse sine signals, and an adder 3-1 and a subtracter 4-2 which input their outputs. The outputs of the adder 3-1 and subtracter 4-1 are converted into the reverse sine signals by the function circuits 6-1 and 6-2 individually and their outputs are inputted to the adder 3-2 and subtracter 4-2 to obtain signals of an X-axial and a Y-axial tilt angle not by linear approximation, but the arithmetic and signal conversion of the inclinometers 1 and 2. Consequently, axial interference due to the X-axial and Y-axial tilt angles is evaded and the measured angle range need not be limited.

Title: Temperature controller for solid element
Inventor: MAEDA FUMISADA
IPC: G02F1/37
Filed: 1993-04-13
Abstract: PURPOSE:To vary the temperature of the solid element more securely and precisely by providing a coating body which covers the periphery of the solid element and is made of a material having larger heat conductivity than the solid element. CONSTITUTION:The solid element 1 is covered with the coating body 2 made of the material which has larger heat conductivity than the solid element 1. Denoting the temperature of fluid, e.g. air at the periphery of the solid element 1 as TA, a control target temperature as TB, and the temperature of the solid element 1 as TC, heat conduction is caused between the solid element 1 and fluid when TCnot equal to TA, to cause heat movement in the solid element 1 and when the heat conductivity of the solid element 1 is specially low, a high temperature gradient is generated. Namely, the temperature variation of the fluid surrounding the solid element 1 causes the temperature of the solid element itself to become unstable. For the purpose, the coating body 2 is only provided to reduce the influence of the temperature rise of the fluid at the periphery of the solid element 1 and the temperature variation of the solid element 1 itself can greatly be suppressed.
