To provide mercury-removal adsorbents, a method of producing mercury-removal adsorbents, and a method of removing mercury by adsorption which are capable of realizing efficient removal of mercury by adsorption from liquid hydrocarbon, thermal power station exhaust combustion gas, natural gas, off gas of various process plants, and so on which contain mercuries in various forms such as elemental mercury, ionic mercury, and organic mercury, and a concomitant hindering mercury adsorption.Mercury-removal adsorbents carrie potassium iodide in an amount of 27 to 70% of a total adsorbent weight, and a volume of pores with a 1 μm pore diameter or more in the mercury-removal adsorbents is 0.6 mL/g or more. These mercury-removal adsorbents are filled in, for example, an adsorption tower 10, and a hydrocarbon liquid is passed therethrough (mercury removal step). In a case where the hydrocarbon liquid contains saturated water, a dehydration unit 9 or the like is installed on a preceding stage of the adsorption tower 10 to dehydrate the hydrocarbon liquid (dehydration step).

A filter is set by a control apparatus automatically detecting a vibration frequency and determining a filter to be needed, in a simple method that does not require a special process.A servo control apparatus which drives a servo motor includes a vibration detection section which detects vibration of a control system, and a vibration frequency measuring and analyzing section. The vibration detection section detects the vibration when the vibration is generated during driving. The vibration frequency measuring and analyzing section measures a frequency of which vibration frequency component is large. Then, a frequency of a vibration suppression filter is set based on the vibration frequency.

A power generation control device for determining a crank position of an engine to reduce a start-up torque following an engine stop, enhancing startability, and reducing electric power consumption of a battery at start-up is provided. The power generation control device includes a magneto generator rotated by an engine, a generated electric current controller that rectifies an alternating electric current generated by the magneto into a direct current and supplies the direct current as a generated electric current to an electric appliance and controls a power generation amount to the electric appliance. A controlling section controls a power generation amount of a rectifying section. The controlling section is provided with an exhaust stroke stop estimation time control module for calculating engine rotational speed and acceleration values based on a signal related to a rotation cycle of a crankshaft or the magneto generator, for estimating a stop of the engine according to the rotational speed and the acceleration values, and for performing a control for increasing the power generation amount of the rectifying section when the engine stop is estimated to occur at an exhaust stroke of the engine.
摘要:
It is an object of the present invention to provide a method for extracting a maximum gain of a servo controller in which while a machine is vibrated by raising a control gain, the vibration is rapidly detected so that the machine does not greatly vibrate or noise is not generated.In a method for extracting a maximum gain of a servo controller for driving a servo motor, a simulated disturbance torque is applied to a torque command by a vibrating unit while a control gain is raised and the vibration of a control system is detected by a vibration detecting unit (1). A process for applying the simulated disturbance torque is repeated while the control gain is raised until the vibration of a prescribed level is detected. The control gain when the vibration detecting unit (1) detects the vibration exceeding the prescribed level is set as a maximum gain.
