  • Patent number: 10818502
    Abstract: Systems and methods are disclosed for plasma discharge ignition to reduce surface particles and thereby decrease defects introduced during plasma processing. A microelectronic workpiece is positioned on a holder within a process chamber that includes a first radio frequency (RF) power source configured to couple RF power to a top portion of the process chamber, a second RF power source configured to couple RF power to the holder, and a direct current (DC) power supply. Initially, a process gas for plasma process is flowed into the process chamber. The process gas is ignited to form plasma by activating the second RF power source to apply RF power to the holder. Subsequently, the microelectronic workpiece is clamped to the holder by applying the positive voltage to the holder with the DC power supply, and the first RF power source is activated to maintain the plasma within the process chamber.

  • Patent number: 10621395
    Abstract: In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase ?[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase ?[i] stored in the memory are calculated as a phase difference ??[i] and a time difference ?t[i]. A phase addition value ?sum[i] obtained by cumulatively adding a plurality of the phase differences ??[i] is calculated so as to correct a phase difference in which the corresponding time difference ?t[i] among the calculated plurality of the phase differences ??[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value ?sum[i].

  • Publication number: 20190303631
    Abstract: A configuration which can easily discriminate a moving wireless (radio) tag from a stationary wireless (radio) tag. The configuration uses an antenna to measure phases of response waves received from a wireless tag. Based on the measurements, the configuration measures changes in distance from the wireless tag to the antenna and detects travel of the wireless tag. Based on the measurements, the configuration measures changes in velocity of the wireless tag relative to the antenna. A wireless tag having a rate of changes in signs of the velocity, of not less than a predetermined value in the measured velocity changes, is detected as being a stationary tag.

  • Publication number: 20190217019
    Abstract: An assembly of the present invention for a syringe includes a piercing needle-attached barrel having a barrel body and a hollow piercing needle fixed to the barrel body and a seal cap for sealing a piercing needle tip. The seal cap has a hollow part and a pierceable part into which the piercing needle tip inserted into the hollow part can be pierced. The seal cap is water vapor permeable and placed in a state in which the piercing needle tip has been pierced into the pierceable part. At least the pierceable part of the seal cap is formed of an elastic material containing silicone rubber as a main material thereof, silicone particles, and a lubricant.

  • Patent number: 8626399
    Abstract: An inverted vehicle travels while maintaining an inverted state. The inverted vehicle includes specifying means for specifying a position at a predetermined distance from a step portion which a rider gets on or off, when the rider gets on or off the vehicle. The specifying means may project a predetermined shape onto the position at the predetermined distance from the step portion, or may cause a vehicle member to move to the position at the predetermined distance from the step portion. The inverted vehicle may further include position detecting means for detecting a position of a foot of the rider, and contact determining means for determining whether the foot is to contact the vehicle, based on the position of the foot detected by the position detecting means.
