Abstract:
A guitar effector module includes: a component circuit board in which an analog guitar effector circuit is formed; a module case in which a knob for adjusting a sound by a circuit is mounted, and the component circuit board is installed therein; and a circuit connection unit, in which a circuit input unit, a circuit output unit, and a circuit power supply unit with respect to the circuit are formed, which is electrically connected with the component circuit board, and is installed on an external side of the module case.
Abstract:
The present invention relates to a method for improving charge/discharge cycle characteristics of a lithium secondary battery using a Si based anode active material, the method comprising surface-treating a surface of an anode current collector to have specific morphology, and preferably vapor-depositing a silicon film, as the anode active material by sputtering under application of bias voltage to the surface-treated anode current collector, and/or disposing an adhesive layer between the surface-treated anode current collector and silicon film, so as to reinforce bondability between the anode current collector and active material, ultimately leading to improvement of charge/discharge characteristics of the battery.
Abstract:
The present invention relates to a submerged hollow fiber membrane module that includes a partition membrane having a slanted slit-shaped opening, and thus capable of not only improving operating efficiency of a hollow fiber membrane module by accelerating the water flow, but also allowing easy discharge of highly concentrated raw water around the hollow fiber membrane to the outside of the module during a reverse wash process.

Abstract:
A probe for an ultrasonic diagnostic apparatus and a method of manufacturing the same are disclosed. The probe includes a sound matching layer having a mounting groove, a piezoelectric member mounted on the mounting groove, a first connector interconnected to the sound matching layer, and a second connector interconnected to the piezoelectric member. The probe permits interconnection of the piezoelectric member to the first and second connectors to be performed rapidly and easily through a single bonding operation, thereby reducing manufacturing time while facilitating the manufacture of the probe.
Abstract:
A retainer for a wafer carrier comprising: a body including a plurality of slots configured to receive side surfaces of wafers; and for each of the slots, a supporting structure formed on a sidewall of the slot and configured to make contact with the side surfaces of a corresponding wafer, the supporting structure being spaced apart from an upper corner of the side surface of the corresponding wafer.
Abstract:
A method comprising: (a) enzymatically processing an O-acetylhomoserine (OAHS) fermentation liquor to produce L-methionine and an acetate source; (b) separating at least a portion of said L-methionine from at least a fraction of said acetate source to form separated L-methionine and a residual liquor comprising an acetate-source; and (c) recovering at least a portion of said acetate source from said residual liquor as recovered acetate.
Abstract:
A composition for a hardmask including copolymer including repeating units represented by Chemical Formulae 1 and 2 and a solvent, a method of forming a pattern using the same, and a semiconductor integrated circuit device including a pattern formed using the method are provided.
Abstract:
A heterogeneous material-containing bottle cap coupled to a container in a content discharge direction comprises a body assembled to a mouth of the container; a storage space coupled within the body; a receiving part having an opening; a discharge member assembled onto an upper main body mouth having the receiving part; a sealing part formed on the lower portion of the discharge member for sealing the opening of the receiving part; and an upper cap having an upper discharge member stopper is caught by and assembled onto an upper side stopper at the top of the discharge member. In such a bottle cap with the above configuration, when the upper cap is open, the discharge member ascends and the sealing part being sealed in the opening is pushed upwards such that the opening of the receiving part is open. Further, an operation part with a dolphin formed in the space is assembled onto the bottom of the receiving part. As such, when the bottle cap with the operation part is assembled onto the container neck, it stops temporarily, as opposed to the bottle neck. Under such circumstance, the body and the receiving part descend together, the dolphin of the operation part pushes the sealing part that is mounted in the opening of the receiving part upward, and heterogeneous materials kept in the storage space of the receiving part are then dropped and mixed through the opening of the receiving part.
