Abstract: A low speed control method and an apparatus for a servo motor. The control apparatus comprises: an encoder capable of acquiring a speed signal from a servo motor and encoding the speed signal to output a low-resolution encoded signal; an insertion calculation unit capable of receiving the low-resolution encoded signal from the encoder to be processed by an interpolation operation for converting the low-resolution encoded signal into a high-resolution encoded signal to be outputted therefrom; a servo control chip capable of setting internal parameters and receiving the high-resolution encoded signal from the insertion calculation unit to be processed by a calculation process so as to output a switch control instruction; and a power module capable of receiving the switch control instruction from the servo control chip and then transmitting the same to the servo motor for adjusting the operation speed of the servo motor.

Abstract: A container having the function of absorbing blood and water of fresh food includes a lower box body, an opening, a lower latch member at the periphery of the opening, a recessed surface at an internal bottom an absorbent material flatly disposed in the recessed surface, and an upper box body corresponding to a lower box body. The lower box body includes an opening, an upper latch member at the periphery of the opening, a plurality of through holes disposed at the bottom corresponding to the absorbent material, and the upper box body is sheathed into the lower box body, and the upper latch member is latched onto the lower latch member, so that the upper and lower box bodies are combined into a double-layer box and the absorbent material is included inside. Further, the lower box body includes a plurality of longitudinal ribs on its internal side wall and perpendicularly contacted with a plurality of transversal ribs on the external sidewall of the upper box body.

Abstract: An open container for raw fish and meat is disclosed to have an inner layer, which is formed of a close-cell foam sheet material having a plurality of through holes through top and bottom sides thereof, an outer layer, which is formed of a close-cell foam sheet material, and an intermediate absorptive layer, which is formed of an open-cell foam sheet material having a cell-opening over 80% and bonded between the inner layer and the outer layer.

Abstract: A sealing and opening structure of a food container having a main body and a top cover. The main body and the top cover include an opening with the outer rim forming a plurality of horizontal and vertical sides. In this way, the top cover can be attached to the top side of the main body with the connection surfaces of one of the horizontal sides or the vertical side forming a grooved-and-tongued joint. The invention features that an ear is formed at the outer rim of the second horizontal side of the main body. An opening handle corresponding to the ear of the top cover is extended outwardly from the fourth horizontal side while the opening handle is substantially triangular. Both sides relative to the center line (x-x) of the surface of the opening handle include a stiffening groove, and the external side of the top cover terminates at an edge portion extended downwardly from the outer rim of the opening handle.

Abstract: A cake case is disclosed to include a base member, which has first female retainers and a second female retainer, and a cover member, which has first male retainers and a second male retainer respectively connectable to the first female retainers and second female retainer to lock the cover member to the base member upon a rotary motion of the cover member relative to the base member. Each first female retainer defines a single open-end retaining groove for receiving one first male retainer to limit the angle of rotation of the cover member on the base member. Each second male retainer has two raised portions that are respectively stopped at two sides of the second female retainer to lock the cover member to the base member after insertion of the second male retainer into the second female retainer.

Abstract: A food container sealing structure is constructed to include a container body having a peripheral coupling flange, and a cover having a peripheral coupling flange coupled to the coupling flange of the container body to seal the container body, the coupling flange of the container body having endless concave portions respectively formed in horizontal section and vertical section thereof, the coupling flange of the cover having endless convex portions respectively formed in horizontal section and vertical section thereof and respectively engaged into the endless concave portions of the container body.

Abstract: A storage box includes an upper cover integrally connected at a rear edge to a lower cover. The upper and the lower covers are provided along their peripheral edges with a recess and a flange, respectively, that engage with each other when the upper cover is closed onto the lower cover. Upper and lower marginal belts surrounding the recess and the flange, respectively, are provided with projections, so that a gap always exists between the two marginal belts to facilitate easy opening of the upper cover relative to the lower cover. The recess and the flange are provided with tongues that abut on each other to lock the upper cover to the lower cover but allow a fit clearance between the recess and the flange, so that the upper and the lower covers would not become stuck at the recess and the flange.

Abstract: The present invention relates to a foldable carrying handle for a portable lunch-box which is made of plastic and consists of seven pieces which are hingedly interconnected into one-part bar-shaped body. The one-part bar-shaped body includes a cross bar, two upper overlapping pieces, two lower overlapping pieces and two positioning pieces. The cross bar corresponds to the width of the lunchbox and is positioned at the center of the bar-shaped body. The two upper overlapping pieces are symmetrically disposed at both ends of the cross bar. The two lower overlapping pieces are symmetrically disposed at outer end of both upper overlapping pieces. The two positioning pieces having finger-shaped fastener are symmetrically disposed at outer end of both lower overlapping pieces.
