Abstract: A pick worn on the finger or thumb of a player of a stringed instrument to aid in the plucking of the strings. The pick rests comfortably like a saddle upon the upper surface of the finger because it's large inner surface mimics the unique contour of the finger or thumb, enabling the pressure required to secure it to be distributed equally on the finger. It has a picking edge that is placed at a point on the finger where the string naturally first contacts the finger, making for a very natural playing experience. The angle of orientation of the picking edge allows the string to move easily and quietly across the striking surface, reproducing the sound of a traditional flat pick. It's unique design holds it place without slipping using wide and thin elastic band which also eliminates unwanted noise from inadvertently contacting adjacent strings.

Abstract: [Problems] Attempts have already been made to effectively utilize the by-produced hydrogen chloride in the exhaust gas discharged from the step of producing polysilicon. Hydrogen in the exhaust gas, too, has been partly utilized without using but discarding, however, the purge hydrogen that is used for desorbing the hydrogen chloride adsorbed in the above step. The invention recovers highly pure hydrogen from the exhaust purge gas and reuses it as a hydrogen source in other production steps contributing to greatly reducing the disposal cost and the cost of producing polysilicon. [Means for Solution] The hydrogen chloride contained in the exhaust gas discharged from the step of depositing polysilicon by using trichlorosilane, is adsorbed by active carbon. The active carbon layer is then purged with the hydrogen gas, and the adsorbed hydrogen chloride is desorbed.
