First and fourth phase difference signals, and first and second phase difference information signals respectively having first, fourth, second and third phase differences may be generated using an input signal and a plurality of clock signals each of which has different phase with each other. A level of the first phase difference information signal may be lowered, and a second phase difference signal having a first level less than levels of the first and fourth phase difference signals may be generated. A level of the second phase difference information signal may be lowered, and a third phase difference signal having a second level less than the levels of the first and fourth phase difference signals may be generated. The level of the phase difference signals having a phase difference lower than 45° may be lowered, and thus the operational speed of a CDR device may be maintained and / or the jitter characteristics may be enhanced.

A chip stack may include a first chip and a second chip stacked on the first chip. Each of the first and second chips may include a substrate having an active surface and an inactive surface opposite to the active surface; an internal circuit in the active surface; an I / O chip pad on the active surface and connected to the internal circuit through an I / O buffer; and a I / O connection pad connected to the I / O chip pad through the I / O buffer by a circuit wiring. A redistributed I / O chip pad layer may be on the active surface of the first chip, the redistributed I / O chip pad layer redistributing the I / O chip pad. The I / O connection pads of the first chip and the second chip may be electrically connected to each other by an electrical connecting part.

A semiconductor memory includes first and second cell arrays for applying a data signal onto pairs of first bit lines and second bit lines, respectively, first and second reference cell blocks each of which applies a reference signal onto a corresponding bit line bar or a corresponding bit line when the data signal is inputted to the corresponding bit line or the corresponding bit line bar, and a sense amp for sensing and amplifying a difference of data signals applied onto one pair of bit lines connected thereto of the pairs of first and second bit lines, wherein each bit line maintains a floating state without an input of an extra pre-charge voltage upon a pre-charge operation, and the other pair of bit lines disconnected to the sense amp are pre-charged with the reference signal by the corresponding reference cell block.

A control unit for a work machine that allows automatically obtaining optimal operability even when the weight of a work arm in the work machine is changed. In a work machine where at least a part of a work arm to be operated by a fluid pressure actuator is provided so as to be replaceable, a control unit for a work machine includes: a pilot-operated control valve that controls the fluid pressure actuator; a proportional solenoid valve that pilot-controls the pilot-operated control valve by a pilot control pressure according to an electrical signal corresponding to a manual operation amount; a measuring means that measures a weight of at least the part of the work arm; and a controller that converts characteristics between the manual operation amount and the pilot control pressure of the proportional solenoid valve to characteristics according to the weight of the work arm measured by the measuring means.

The invention discloses a water purification method based on an ecological net cage, using a double-layer net cage as a carrier, stocking filter-feeding fish in the upper box, fixing submerged plants in the lower box, putting the net cage into the water area, and carrying out Water purification. The method of the present invention is based on the comprehensive utilization of the net cage and the water environment ecosystem, without providing additional energy, and the net cage module can be continuously operated only by solar energy and bioenergy in the water environment, and there is no secondary pollution problem. This method can alleviate the algal bloom problem caused by eutrophication of the water body, can effectively reduce the concentration of nitrogen and phosphorus in the water body, requires only a small amount of manual intervention, has the advantages of simple operation and low cost, and is suitable for the ecological environment of lakes, rivers, and reservoirs. governance and improvement.

The invention discloses a processing system and process of soybean meal for feed, and relates to the technical field of feed processing. The processing system includes a hot blast furnace, a monolithic processing line and a powder processing line; the monolithic processing line includes sequentially connected first drum-type feed drying Dryer, the first pulverizer, the first screening machine and the first drying mechanism, the powder processing line includes the second pulverizer, the second drum feed dryer, the second screening machine and the second drying mechanism connected in sequence mechanism. The soybean meal processing system for feed provided by the present invention adopts the processing mode of one furnace for multiple lines, which reduces the energy consumption of the equipment under the premise of ensuring the drying effect; the whole material processing line and the powder processing line are set at the same time, which can The moisture content of the raw materials is different, and the corresponding production line is selected to meet the processing needs of soybean meal raw materials with different moisture contents; at the same time, multiple production lines can be used together to keep the equipment in operation as a whole, and will not cause problems due to the uneven moisture content of soybean meal raw materials. Equipment down.

In a crosshead type two-stroke internal combustion engine, the rotation position of piston ring relative to adjacent piston is forcibly changed in the below way. Because the engine is set to continuously run at preset constant load or constant speed, the forcible change of the rotation position of piston in cylinder is effected by at least load fluctuation on the cylinder, so that the mean effective pressure in the cylinder changes at least 0.5bar, and is effected by keeping the changed load for a certain time in the said cylinder.

The invention discloses a method for collecting blue algae and purifying water quality by breeding algae-eating fishes in a water body. The method provided by the invention is characterized in that a plurality of uniformly distributed net cages used for breeding algae-eating fishes are arranged in an algae-controlling water area; the bottom of each net cage is equipped with a fish manure collector which is made from a dense net; the algae-eating fishes are bred in the net cages; and an algae manure interception net is arranged on the edge of the water area in which the net cages are disposed.According to the invention, the algae manure interception net, a fish-interception and blue algae-capture module and an ecological floating-island water quality purification module are arranged in local water areas, so as to effectively control the biomass of blue algae in water source areas, effectively reduce the content of N and P in a water body, improve the safety of water consumption, and obtain the cycling support economically.

A low-power storage device is provided. The storage device includes a first transistor, a second transistor, a logic element, and a semiconductor element. The second transistor controls supply of a first signal to a gate of the first transistor. When the potential of a second signal to be input is changed from a first potential into a second potential lower than the first potential, the logic element changes the potential of a first terminal of the first transistor from a third potential lower than the second potential into the first potential after the logic element changes the potential of the first terminal of the first transistor from the second potential into the third potential. The semiconductor element has a function of making a second terminal of the first transistor floating. The first transistor includes a channel formation region in an oxide semiconductor film.
