摘要： An ink contains at least a first solid particle, and a second solid particle formed of a base material of a different main component from that of the first solid particle. The first solid particle and the second solid particle have zeta potentials of the same polarity, or zeta potentials of 0±5 mV. The first and second solid particles in the ink have the same surface property, specifically the same interface property in the ink. This makes it possible to use a common dispersant suited for adsorption on the first and second solid particles. In this way, more than one kind of solid particle can be stably dispersed using a sole kind of dispersant.

摘要： A clock generator includes a first circuit, a second circuit, and a third circuit. The first circuit generates a first clock signal. The second circuit divides the frequency of the first clock signal to generate a second clock signal. The third circuit generates a third clock signal from the first and second clock signals. The third clock signal has the same period as that of the second clock signal, and timing at which the third clock signal changes from a first logic level to a second logic level coincides with timing at which the first clock signal changes from a first logic level to a second logic level.

摘要： An air-fuel ratio sensor in which the temperature dependence as well as the pressure dependence of a detection signal obtained by the air-fuel ratio sensor are suppressed to thereby improve the accuracy in air-fuel ratio by the air-fuel ratio sensor, which is not influenced by deposits in an exhaust gas and which is high in durability. The suppression is achieved by using a gas-diffusion limiting portion having such critical parameters as 10-30% porosity, 1-3 micrometers mean pore size and 200-1000 micrometers thickness. Alternatively the parameters may be 15-25% porosity, 0.1-7 micrometers pore size and 400-800 micrometers thickness.
