Abstract: Improved searching for network-based publication systems is provided via improved item listings. A set of rules is obtained that include string similarity functions generated from character patterns that contain unconventional character sequences not included in user search queries. Marketplace listing information is obtained from a user, where the marketplace listing information includes a listing title. The listing title is analyzed using the set of rules to identify at least one character pattern in the listing title based on a similarity between the listing title and the at least one character pattern determined using at least one of the string similarity functions. A request for a new listing title is generated based on identifying the at least one character pattern in the listing title.

Abstract: One example embodiment relates to a method that comprises receiving marketplace listing information from a user, the marketplace listing information including a listing title, and accessing a plurality of character patterns for attracting attention to marketplace listings. The method includes analyzing, using one or more processors, the listing title to identify at least one of the plurality of character patterns in the listing title. A request for a new listing title is generated based on identifying at least one of the plurality of character patterns in the listing title.

Abstract: A self-oscillation type resonant flyback converter includes a series combination of a primary winding and a switching transistor. A secondary winding is connected to a power diode and to an output capacitor. A feedback winding is connected to a delay driving circuit comprising a delay diode, a constant-current diode and a capacitor. The delay driving circuit is provided to delay a positive feedback signal from said feedback winding, so that when said power diode becomes non-conducting, said delay diode becomes in the reverse conduction state, starting a free resonance period that concludes when the said delay diode becomes non-conducting and the switching transistor is achieved at zero voltage switching.

Abstract: A juicer/mixer includes an actuating device for providing electrical power to a rotating shaft thereon, to which a squeezing housing device is engaged, thus allowing food to be processed in the squeezing housing device. Food is milled in the squeezing housing device and, after double filtering, juice is obtained from a juice outlet, and the dregs are remained in an inside wall of the squeezing housing device. A dreg displacement switch is provided to trigger a stopper to expel the dregs via a dreg outlet device by utilizing centrifugal force.
