Abstract: A fuel-additive supplying apparatus includes: a container having an upper part formed with a vapor through-hole; a vapor-confining conduit extending in the container from the upper part; an elongate header mounted to and extending in the container from the upper part; and a heater controller connected electrically to the elongate header. The vapor-confining conduit is spaced apart from and surrounds the elongate heater and a bottom end of the vapor through-hole, so that a fuel-additive vapor generated in the vapor-confining conduit may be introduced into an intake manifold of an engine through the vapor through-hole.

Abstract: An osteotome includes a connector, a first arm, a second arm, a third arm, a fourth arm and a cutting head. A coordinate system has an X axis, a Y axis, and a Z axis. The X axis, the Y axis and the Z axis are perpendicular to each other and intersect at an original point. The connector extends along the Y axis. The first arm, extending along the Y axis, connects to the second arm, extending along the plane with the X and Y axes. An angle between the first and second arms is within a range between 125 to 145 degrees. The third and fourth arms respectively extend along the Z axis and the X axis. The cutting head is parallel to the X axis and the Y axis so as to easily control the insertion angle of the osteotome for the patients with smaller face or smaller oral cavity.

Abstract: A variable focus device is adapted for focusing an image on an image sensing module, and includes a hollow fixing seat, a lens module and a lens coupling unit. The fixing seat is adapted for mounting the image sensing module therein. The lens coupling unit includes a piezoelectric layer and a metal layer disposed on the piezoelectric layer. The piezoelectric and metal layers are respectively formed with aligned lens mounting holes to permit mounting of the lens module to the lens coupling unit. The lens coupling unit is disposed relative to the fixing seat such that the lens module corresponds in position to the fixing seat. The piezoelectric layer deforms in response to application of a control signal thereto to move the lens module relative to the fixing seat, thereby varying a focal position of the lens module relative to the image sensing module in the fixing seat.

Abstract: A process for preparing a frozen shrimp product includes the steps of: (a) placing a first raw shrimp in a confining space of a confining member; (b) stacking a second raw shrimp on the first raw shrimp in the confining space of the confining member using a binder; (c) pressing the second raw shrimp against the first raw shrimp in the confining space of the confining member so as to form a shrimp product; (d) taking out the shrimp product from the confining member; and (e) freezing the shrimp product taken out from the confining member.

Abstract: A process for the preparation of a shrimp product includes the steps of: (a) preparing first and second raw shrimps; (b) decapitating and removing all of the shell from the first raw shrimp; (c) decapitating and removing all but a tail segment of the shell from the second raw shrimp; (d) forming a cutting slit in a head portion of the second raw shrimp; (e) extending a tail portion of the peeled first raw shrimp into the cutting slit in the head portion of the second raw shrimp; (f) applying an edible binder to the contact area between the head portion of the peeled second raw shrimp and the tail portion of the peeled first raw shrimp so as to bind the first and second raw shrimps together to form a composite product; and (g) freezing the composite product.

Abstract: In a method of making fish skin leather, a fish skin with fish scales thereon is washed, cleaned, and tanned. Then, the fish scales are removed from the tanned fish skin to expose a plurality of ridges underlying the fish scales and presenting fish skin grains. The resultant fish skin leather has a skin substrate having a surface with fish skin grains that include a plurality of ridges which project from the surface of the skin substrate.

Abstract: A multi-layer platter apparatus includes an extensible elongated rod having a plurality of hollow tapered sections which are disposed concentrically one around the other in a retracted position and which are movable relative to one another along the length of the rod, the tapered sections having recesses and projections such that the recesses of each of the tapered sections interengage the projections of an adjacent one of the tapered sections in an extended position. The apparatus further includes a plurality of platters mounted respectively on the tapered sections.

Abstract: A plate for placement of cooked and frozen shrimps includes a base plate portion and a riser portion. The base plate portion has top and bottom sides, a plurality of spaced apart elongate projections which extend downward from the bottom side, elongate drain grooves which extend respectively in the projections and which open at the top side and close at the bottom side, and a receiving space above the top side and communicated with the drain grooves. The riser portion extends laterally and upwardly from the base plate portion and loops around the receiving space.
