A color toner including toner particles including a colorant, a binder resin, and a wax; and an external additive including at least one of an inorganic particulate material and a particulate resin, wherein the binder resin includes a polyester resin (A) having a crystallinity and a formula (—O—CO—CR1=CR2-CO—O—(CH2)n—)m, wherein R1 and R2 independently represents a hydrocarbon, and n and m are repeating numbers; a resin (B); and a resin (C), wherein the resins (B) and (C) and the wax have an island-sea structure such that the resin (C) is present like islands in a sea of the resin (B) and the wax is substantially included in the resin (C). A toner container, an image forming method, an image forming apparatus and a process cartridge including the color toner are also provided.

A light source comprising sidelight type backlight light guide plate (L), wherein a transmittance angle dependent layer (T1) which transmits normally incident light and reflects obliquely incident light is disposed on one surface of the sidelight type backlight light guide plate (L), and a reflection plate (R) having a repetitive slope structure is disposed on the other surface of the sidelight type backlight light guide plate (L). The invention light source is less in absorption loss due to repetition of light reflection and the like.

This invention discloses a semiconductor power device disposed in a semiconductor substrate and having an active cell area and an edge termination area wherein the edge termination area comprises a wide trench filled with a field-crowding reduction filler and a buried field plate buried under a top surface of the semiconductor substrate and laterally extended over a top portion of the field crowding field to move a peak electric field laterally away from the active cell area. In a specific embodiment, the field-crowding reduction filler comprises a silicon oxide filled in the wide trench.

The present invention relates to a constant gradient field nuclear magnetic resonance (NMR) rock sample analysis method and instrument. The method includes: in a constant gradient magnetic field, performing NMR measurement to acquire data; converting the measured NMR data into a two-dimensional NMR spectrum D-T2; performing measurement and inversion on a standard sample of a constant gradient field to obtain a standard sample two-dimensional NMR spectrum D-T2; measuring the sample to acquire a two-dimensional NMR spectrum D-T2 of a fluid in the sample; identifying fluid types according to the practically measured two-dimensional NMR spectrum D-T2; computing the fluid property and the petrophysical parameters according to the two-dimensional NMR spectrum D-T2 of the fluid in the sample; performing single slice scanning on the sample to acquire partial oil and water saturation; performing continuous slice scanning to obtain axial oil and water saturation distribution and movable fluid saturation distribution of the sample.

The present invention relates to a connector. Aforementioned connector includes a first connecting member, a second connecting member, and a third connecting member. The first connecting member includes a first case, a first insulator, and a first conductive terminal, wherein the first case defines a first receiving chamber therein, the first insulator is received in the first receiving chamber, an external sidewall of the first case is provided with a first step. The second case defines a containing hole, the PCB board is received in the containing hole, a first end and a second end of the second case each defines a latching groove, the latching grooves is in communication with the containing hole. The third connecting member includes a third case, a second insulator, and a second conductive terminal, wherein the third case defines a second receiving chamber therein. In above connector, because the electrical components coupled to opposite ends of the connector can slide along three directions which are perpendicular to each other, such that a problem of a difficulty of a connection between the connector and the electrical components which is caused by a deviation of the design of the structure of the electrical components can be avoided, thereby a tolerance insensitive of the connector is enhanced.
