Abstract: A method for measuring multimedia communication quality is disclosed. The multimedia video communication quality may be objectively reflected through the embedment and extraction of digital watermark under a precondition that the quality of the multimedia video data is not obviously affected. In the invention, each frame of the multimedia video data is uniformly divided into blocks of equal size and watermark data is embedded in each of the blocks, so that the watermark may be uniformly distributed. The multimedia video data are divided into groups, and the watermark is embedded in a part of the frames with equal interval between the frames in each group to reduce the effect of the watermark on the data. The watermark information is directly embedded in the spatial domain of the original video data. The PSNR of the video data is linearly fitted using the accuracy rate of the recovered watermark relative to the original watermark, and the fitted PSNR is regarded as a measurement indication of the multimedia video communication quality. Post-processing such as smoothing filtering is performed on video frames after watermark extraction to eliminate the effect of the watermark on the multimedia video data quality.

Abstract: If there is static friction, the magnetic pole position estimation is completed at the time when error torque used for magnetic pole position estimation becomes less than the friction, so that there remains magnetic pole error. A problem has been that when the error torque becomes less than a forward static friction, there remains a positive magnetic pole deviation and when the error torque becomes less than a backward static friction, there remains a negative magnetic pole deviation. By shifting in the negative direction and the positive direction initial values for estimating a magnetic pole error in operation sets, a true pole-error estimation value is estimated in the use of a pole-error estimation value having a positive magnetic pole error obtained by the positive shift operation and a negative one obtained by the negative shift operation, which can reduce estimation error due to the static friction.

Abstract: There is provided an electric ground working vehicle (10) including a left wheel (14) and a right wheel (16), at least one caster (19), a working apparatus (22), an acceleration operating element (44,46) for performing acceleration instructions, a turn operating element (42) for performing turn instructions, and a control unit (40). The left wheel (14) and the right wheel (16) are independently driven by left and right electric motors (26,28) respectively. The control unit (40) controls a regenerative brake driving unit so that electric power is regenerated from the left and right electric motors (26,28) to an electric power source unit when the acceleration operating element (44,46) is not operated during traveling to regeneratively brake the left and right wheels (14,16). The control unit (40) controls the brake force of the wheels (14,16) so that the brake force of the wheel at the inside of a turn, among the left wheel and the right wheel (14,10), can be made greater than the brake force of the wheel at the outside of a turn when the acceleration operating element (44,46) is not operated during traveling and turn instructions are inputted from the turn operating element (42).

Abstract: <P>PROBLEM TO BE SOLVED: To provide a dry cleaning device which can stably irradiate ultraviolet rays and can suppress heat at the time of irradiating the ultraviolet rays.  <P>SOLUTION: The dry cleaning device is provided with a light-emitting diode 14 irradiating an inner part of a reaction container 11 where an object to be cleaned such as a semiconductor wafer is stored with the ultraviolet rays and a gas introduction means introducing cleaning gas comprising ozone into the reaction container 11. Since the intensity of the ultraviolet rays that the light-emitting diode 14 emits is stable, a surface of the object to be cleaned can be cleaned without spots. Since the start of emitted ultraviolet ray illuminance is fast in the light-emitting diode 14, the processing capacity of the cleaning device 10 can be improved. The light-emitting diode can easily adjust luminance compared to an ultraviolet lamp. Since the light-emitting diode has very little irradiation of heat, the object to be processed does not deform by heat, and a degree of freedom on material selection is large.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To arouse a player's interest in a bonus game to be terminated as tokens in the number reaching a prescribed number are put out.  <P>SOLUTION: The operation of BB (big bonus) is terminated on condition that tokens in the number reaching the prescribed number are put out, and the operation of MB (middle bonus) is terminated on condition that an internal winning combination "SB (single bonus)" is determined in addition to the above condition. RT (replay time) is started when the operation of BB or MB is terminated, and terminated when a combination of SB symbols is displayed. When a specific internal winning combination is determined in the BB state, a first counter is updated, and as a result, when the updated counter value satisfies a threshold, the player is informed that the internal winning combination "SB" is determined in the RT. When the combination of SB symbols is displayed in the MB state and when termination of the RT cannot be avoided, a second counter is updated, and as a result, when the updated counter value satisfies a prescribed threshold, the first counter is updated by a relatively large value in the BB state. When the operation of the BB or MB is terminated and when the operation of RT is continued in the next game round or thereafter, the second counter is cleared.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To improve the accuracy of density control of a toner image in a high density area.  <P>SOLUTION: The density Da of an image A for setting a target density which is a high-image density is divided by the density of an image for setting a target density which is an image density lower than the former one, thereby obtaining a density ratio RH. If the density ratio RH is equal to or greater than a threshold, a control section determines that the density of an image in a high density area is too high, and decreases the target density of an image for density control. For example, if a certain high image density (e.g., 100%) of an image further increases, the density ratio RH becomes significantly high. This configuration prevents the density of a toner image from excessively increasing in a high density area. Accordingly, this surely prevents, for example, toner concentration in a developing device from becoming too high, with the result that the interior of an image forming apparatus or a sheet are soiled, a photoreceptor, and so on are fogged with toner, and an amount of toner forming a toner image transferred to the sheet excessively is increased, leading to troubles, such as, fixing failure.  <P>COPYRIGHT: (C)2010,JPO&INPIT
