A portable, multi-mode, multi-user cooler for storing and selectively dispensing beverages. A plastic, cylindrical container forms a hopper that mounts a removable top. Multiple, external recessed channels are formed in the container at radially spaced-apart locations. Deployable legs formed of multiple segments are housed within the channels when retracted. A plurality of user-actuable dispensing spigots that are radially spaced-apart around the periphery of the body are located between adjacent legs. Legs are deployed by unfolding them once removed from the storage channels. Selectively deployable, coaxial sleeves fitted to leg elements can be slidably deployed to lock the knees in axial alignment to secure and brace the legs. An internal divider partitions the container volume into separate compartments aligned with separate radially spaced-apart spigots.

A slim speaker includes a casing having an enlarged front opening and a rear end with a magnetic circuit mounted thereto; a voice coil located over a central area of the magnetic circuit; a diaphragm located between the enlarged front opening of the casing and the voice coil; and a damper located behind the diaphragm to space from the latter. The diaphragm has at least one V-shaped bent section provided at a middle portion for bearing on a corresponding position on the damper. With these arrangements, the diaphragm not only has an effectively reduced overall height to largely reduce the assembled volume of the slim speaker and allow the slim speaker to be easily mounted in the limited inner space of an electric product, but also stabilizes the vibration of the voice coil to enable good resonance of sound.

The present invention provides a self-draining oil buoyancy regulating device for underwater robots, wherein the accumulator, lower hatch cover, hatch trunk, upper hatch cover and bladder are connected; the water-proof connector is fixed on the upper hatch cover; the depth-pressure sensor is settled on the lower hatch cover; the upper valve block, hydraulic-operated check valve and lower valve block are connected; the lower valve block is fixed on the lower hatch cover; the pump outlet pressure sensor and the accumulator pressure sensor are on the lower valve block; the directional valve and the upper valve block are connected; the hydraulic pump motor assembly and the relief valve are both connected with the lower valve block; the depth-pressure sensor, pump outlet pressure sensor and accumulator pressure sensor are all connected with the control panel; the control panel is connected with the external power supply and the host computer.

The invention belongs to the technical field of preparation of printed circuit boards and discloses a preparation method of a PCB with a step groove. The method comprises the following steps of (A) providing a bottom substrate and fabricating a circuit pattern on the bottom substrate; (B) providing a to-be-laminated substrate, embedding a glue stop block into one side, toward the bottom substrate,of the to-be-laminated substrate, and laminating and molding the to-be-laminated substrate and the bottom substrate which are superimposed from top to bottom into a multi-layer board; (C) forming a groove corresponding to the glue stop block in the other side, opposite to the bottom substrate, of the multi-layer board, taking out the glue stop block from the groove and obtaining a first groove with a nonmetallic side wall; and (D) forming a second groove of which the cross section area is smaller than that of the first groove in the bottom of the first groove to obtain the PCB with the step groove. According to the preparation method, through the arrangement of the glue stop block before laminating and molding, the first groove can be accurately formed in a circuit pattern region betweenthe to-be-laminated substrate and the bottom substrate; and through the arrangement of the second groove, the space of the step groove is more fully utilized.

The invention relates to the technical field of circuit board production, and discloses a PCB having multi-step ladder grooves. One side of the PCB is provided with a first groove, and the groove bottom and the groove wall of the first groove are metallized; a second groove is formed in the groove bottom of the first groove, and the groove bottom and the groove wall of the second groove are metallized; a through slot is formed in the groove bottom of the second groove, and the groove wall of the through slot is not metallized. The PCB with the multi-step ladder grooves according to the presentinvention can realize the mounting of the special-shaped components or the selective mounting of the components, fully utilize the space of the ladder grooves, and reduce the installation volume of the PCB.

Some embodiments of the present disclosure provide the design and manufacture of an ultra-small chip assembly. The ultra-small chip assembly comprises a die, a plate-like back electrode disposed on the back-side of the die, and one or more plate-like positive electrodes disposed on the front-side of the die. The ultra-small chip assembly is configured such that one end of the plate-like back electrode extends beyond a first side of the die, and each of the one or more plate-like positive electrodes includes an end which extends beyond a second side of the die. By attaching both the plate-like back electrode and the plate-like positive electrodes on the surfaces of the die, and directly using the exposed ends of the plate-like electrodes as the lead-out electrodes for the chip assembly, the electrical connections outside of the die only occupy a very small volume.
