  • Electrolytic cell and electrolytic device
    Patent number: 11946151
    Abstract: An electrolytic cell capable of simply electrolyzing carbon dioxide into carbon monoxide and oxygen with low activation energy, and an electrolytic device. The carbon dioxide electrolytic cell includes a cathode, an anode, and a solid electrolyte having oxide ion conductivity. The cathode is the following (A) or (B); (A) a metal and a first mayenite-type compound are included therein or (B) a metal and a second mayenite-type compound are included therein, said second mayenite type compound including a mayenite type compound having electron conductivity.

  • Method for manufacturing a wheel bearing apparatus
    Patent number: 9512883
    Abstract: A method for manufacturing a wheel bearing apparatus by measuring a distance Ho, Hi and Hh. A difference ?H=(Hi+Hh?Ho) is compared with a reference value of a model article. Rolling elements are selected with each having an optimum diameter to correct the difference ?H between the measured values and the reference values.

  • Differential output type filter circuit
    Patent number: 5705954
    Abstract: A differential output type filter circuit comprises, between its input terminal and differential output terminal, a reference voltage generator circuit which receives supply voltage Vcc and outputs a reference voltage, an SVR correction circuit which filters out the noise component superposed on said reference voltage, an n-order filter circuit which functions to filter out the noise of an input signal corresponding to the input of this applied signal, this n-order filter circuit being composed of a first-stage primary filter circuit 3 and an (n-1)-order filter circuit 4, and a post-amplifier circuit 5 which receives and differentially amplifies the output signal from the SVR correction circuit and output signal 105 from said n-order filter circuit. This configuration represents a so-called single-signal input type filter circuit, and features compactness and excellent SVR characteristics.
