Title: Insulation resistance measuring method compensated for ground resistance
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1988-09-19
Abstract: PURPOSE:To measure a resistance without being affected by a stray capacity to the grounded by impressing a measuring signal voltage with a frequency different from the commercial frequency to an electric circuit and detecting a leak current fed back to the grounded line and a voltage existing between the electric circuit and the ground. CONSTITUTION:The signal voltage with a constant frequency for the measurement having the frequency f1 different from the commercial frequency is impressed to the electric circuits L1, L2 through an oscillator OSC which is connected to the grounded line LE. The leak current fed back through an insulation resistance R and the stray capacity C to the ground is detected by a current transformer ZCT passing through the grounded line LE. Components of the frequency f1 included in an output of the ZCT are detected by a filter FILT and inputted to one of the input terminals of a synchronous detector MULT. To another input terminal of the MULT, an output coming from the detection of the voltage between the electric circuit L2 and the ground E3 by an amplifier (A) having a high input impedance, is impressed. When the output of the MULT is impressed to an LPF1, the output OUT becomes the value which is inversely proportional to the resistance R and freed from the effects of the ground resistance (r) and the capacity C, and the resistance R can be detected since the measuring signal voltage is already known.

Title: Silicon carbide filament-reinforced ceramic-based composite material
Inventor: SUYAMA AKIKO
IPC: C04B41/85
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To improve fracture toughness and fracture energy while sufficiently keeping the high strength to a high temperature region by regulating the thermal expansion coefficient of a ceramic matrix including polycrystal silicon carbide filaments compounded therewith and having a stoichiometric ratio within a specified range so as to be same to or less than the thermal expansion coefficient of the silicon carbide filament. SOLUTION: The stoichiometric ratio of Si to C is regulated so as to satisfy the formula 0.9<=C/Si<=1.1. The thermal expansion coefficient αm of the ceramic matrix and the thermal expansion coefficient αf of the silicon carbide filament preferably satisfy the formula 0.6αf<=αm<=αf. The strength or the like is improved by regulating the thermal expansion coefficient of the matrix so as to be >=60% of that of the fiber. The improvement of the fracture toughness and fracture energy caused by the pullout, the bridging or the like of the fiber is expected because when the composite material is cooled to room temperature, the shrinkage of the fiber is smaller than that of the matrix when the thermal expansion coefficient of the matrix is smaller than that of the fiber.

IPC: H02H5/10
Filed: 1984-11-07
Abstract: PURPOSE:To immediately diagnose the presence or absence of the breakage of a rotor bar, by inputting the current of a stator and a rotary speed signal. CONSTITUTION:The pulse wave form obtained by a rotary frequency detection circuit 9 is inputted to a number-of-rotation analysis circuit 24. When the rotor bar of an induction motor is broken, the secondary current of a rotor comes to non-equilibrium and, therefore, a current having frequency of f0(1-2s) is flowed to the winding of a stator and, as this result, the wave form of the current of the winding of the stator comes to a wave form wherein a current with power source frequency f0 and the current with frequency of f0(1-2s) are superposed to generate a beat wave form wherein amplitude changes with frequency of f0-f0(1-2s)=2sf0. I there is no variation in mechanical load shown at the time of the eccentric rotation of the rotor, center rotary frequency comes to f1=(1-s)f0/p/2 and, therefore, the numerical value displayed on a second beat frequency display circuit 14 becomes equal to that displayed on a first beat frequency display circuit 6 and it is diagnosed that the bar was broken.

Filed: 1986-10-02
Abstract: PURPOSE:To promote the improvement of accuracy of the car speed-responsive characteristic, by providing a means, which absorbs an amount of fluid in a direction decreasing a rear steering amount when a pressure of fluid increases, in a pressure fluid path connecting a cylinder and enabling the absorbing means to regulate its absorbing amount of fluid in accordance with a steering angle. CONSTITUTION:A case 46, having a pressure oil chamber 45, is provided, and the case 46 fits a piston 42 to the pressure oil chamber 45 to be urged to the side of a cover 46a by a spring 43 while connects a communication path 47, which is provided in the cover 46a communicating with the pressure oil chamber 45, to the first pressure oil path. The case 46, which provides in the side of its internal bottom part 46b a rack member 51 holding the rear end of the spring 43 to be stopped, meshes a worm 53 of a stepping motor 52 with a rack part 51a of the rack member 51, and the case 46, in which the rack member is longitudinally moved by driving the motor 52, regulates urging force of the spring 43. Since the piston 42 slides rearward against the urging force of the spring 43 during low speed running operation, an amount of fluid is absorbed by the amount of that sliding of the piston 42.
