A plunger pump, includes: a plunger pump unit including a pump chamber and a plunger for pressing a hydraulic fluid in the pump chamber to perform a discharging operation of the hydraulic fluid; a motor; and a cam portion driven by the motor to rotate and press the plunger. The cam portion has at least two discharge regions for pressing the plunger and a suction region formed between the discharge region. The plunger performs the discharging operation two times or more by one rotation of the cam portion.

A low-cost and practically useful method for preventing global warming by decomposing N2O wherein N2O contained in an N2O-containing gas to be treated can be decomposed at a relatively low temperature; and an apparatus therefor. That is, a method for preventing global warming comprising, in a process of thermally or catalytically decomposing N2O in an N2O-containing gas to be treated, dividing the N2O-containing gas stream to be treated in portions, preheating a portion thereof so as to exothermally decompose N2O in said gas stream to form a hot gas stream, and supplying the remainder of the divided gas stream to be treated into said hot gas stream to thereby continuously decompose N2O, so that global warming is prevented; and an apparatus therefor.

Motion vector encoding and decoding methods, motion vector encoding and decoding apparatuses, and storage media storing motion vector encoding and decoding programs are provided, thereby reducing the amount of generated code with respect to the motion vector. First, the motion vector of a target block to be encoded is detected (step S1), and a prediction error vector is calculated (step S2). After the length component of the motion vector is calculated (step S3), the length component is variable-length-encoded (step S4). The length component is checked (step S5), and if the length component is not 0, the direction component is calculated (step S6). The table for encoding the direction component is selected according to the length component, and the direction component is encoded (step S7).

A scheme for detecting shot boundaries in the compressed video data at high speed and high accuracy. In this shot boundary detection scheme, a Predictive-picture (P picture) change is calculated from a P picture sequence in the input video data which is compressed by an inter-frame/inter-field forward direction prediction coding scheme, according to coded data contained in the P picture sequence, while an Intra-picture (I picture) change is calculated from an I picture sequence in the input video data which is compressed by an intra-frame/intra-field coding scheme, according to coded data contained in the I picture sequence. Then, a shot boundary is detected by evaluating both the P picture change and the I picture change.

If the distribution coefficient of an impurity in a compound melt is less than 1, the impurity concentration in the compound melt doped with the impurity increased during a crystal growth in an LEC method. A supplying device replenishes an undoped crystal into the melt in order to keep the impurity concentration constant. The undoped crystal is covered with a liquid encapsulant which is contained in an encapsulant-supporting-cylinder or double-cylinder. Replenishing rate (dQ/dt) of the undoped crystal and the growing rate (dS/dt) should satisfy the equationdQ/dt=(1-k)dS/dtThe impurity concentration of a grown single crystal is uniform. Whole of the crystal is a single crystal. Electronic properties of the single crystal is uniform from seed end to tail end.

Artificial leather is produced by applying a dope comprising urethane prepolymers containing terminal isocyanate groups, an amine catalyst and a foam stabilizer onto a releasing carrier sheet, exposing the resulting coating layer to a moisture-containing gas under controlled conditions, laminating the coating layer onto a backing material and stripping off the releasing carrier sheet. The resulting artificial leather has a cellular structure of polyurethane microfoam in adhesion with the backing material and an adhesion strength of 100 to 10,000 g/cm of width.
