Filed:

Aug 18, 2010

Appl. No.:

12/859221

Inventors:

JIN WANG - Claremont CA, US

International Classification:

A61M 5/31

US Classification:

604191

Abstract:

A split syringe includes two or more separate syringes held together to become one full cylindrically shaped syringe assembly. The needles of the separate syringes may be held together by a larger outside needle. For example, two half-cylindrically shaped syringes may be joined together to become one full cylindrically shaped syringe assembly.

US Classification:

257 88, 257 99, 257 98, 257E2712, 257E33072, 257E33066

Abstract:

The present invention discloses a LED package structure and a module thereof. The LED package structure comprises a metallic chip-carrying lead frame, a metallic anode lead frame, a metallic cathode lead frame and a forming resin. At least one LED chip is stuck to the metallic chip-carrying lead frame. The metallic anode lead frame and metallic cathode lead frame are arranged beside the metallic chip-carrying lead frame. The forming resin includes a top member, a first sidewall, and a second sidewall. The top member is arranged on the metallic chip-carrying lead frame and has an opening to reveal the LED chip. A reflective wall is formed along the opening. The first sidewall is arranged between the metallic chip-carrying lead frame and the metallic anode lead frame to join them. The second sidewall is arranged between the metallic chip-carrying lead frame and the metallic cathode lead frame to join them.

Abstract:

The present invention discloses a progressive-refractivity antireflection layer and a method for fabricating the same to eliminate light reflection occurring in an interface. The present invention is characterized in being fabricated via depositing a first material and a second material, and having a refractivity (n) gradually varying with a thickness thereof and ranging between a refractivity (n) of the first material and a refractivity (n) of the second material. No matter at what thickness the refractivity (n) of the antireflection layer is measured, the refractivity (n) meets an effective medium theory expressed by an equation: n={nf+n(1−f)}, wherein f is a filling ratio of the first material of the antireflection layer.

Appl. No.:

8/386750

Inventors:

Jin S. Wang - Torrance CA

Assignee:

JMR Research Inc. - Torrance CA

International Classification:

B65D 8557

US Classification:

2063071

Abstract:

A package for the storage and display of products such as video game cartridges and compact disks. The package consists of an elongated strip of transparent flexible plastic or similar material having a series of pockets or pouches attached to the the strip. The package may be hung from a hole at one end of the strip to display the contents of each of the pockets, the pockets all opening upwards towards the end of the strip from which the package is hung. The strip includes hinging portions between the pockets so that the cartridges or disks in the pockets can be folded together, in a zig-zag or accordion fashion to form a compact stack. When folded into a stack, a flap at one end of the strip may be folded over one side of the stack and fastened to the other end of the strip so as to hold the cartridges or disks in place in the stack, but at the same time allowing the side of the stack opposite to the flap to be opened so that the cartridges or disks can be examined one at a time, in a manner similar to opening a book, one page at a time.

International Classification:

C23C 1438

US Classification:

20419218

Abstract:

An acoustic shear wave resonator comprising a piezoelectric film having its C-axis substantially inclined from the film normal such that the shear wave coupling coefficient significantly exceeds the longitudinal wave coupling coefficient, whereby the film is capable of shear wave resonance, and means for exciting said film to resonate. The film is prepared by deposition in a dc planar magnetron sputtering system to which a supplemental electric field is applied. The resonator structure may also include a semiconductor material having a positive temperature coefficient of resonance such that the resonator has a temperature coefficient of resonance approaching 0 ppm/. degree.
