A weapon accessory in the likeness of a human, animal, mythical, or other creature, or a part of the creature, has a longitudinal passageway adapted to allow a projectile to exit the muzzle through the accessory. The projectile passageway opens through a mouth, eye, nose / nostril, or ear structure. Additional apertures selected from these structures, other than the one selected for the projectile exit, may be in fluid communication with the projectile passageway for directing exiting gasses in desired directions, for example, for a muzzle brake. The additional apertures preferably extend generally upward at an angle to said projectile passageway, including straight upward, upward and forward, or upward and rearward, and may also extend to a left or right side. Upper and lower jaws of the creature may be shaped or sized to direct gasses and hence light / flash in desired directions, for example, for flash suppression.

An otoscope provides a disposable speculum sleeve that conducts light to a narrow tip holding an electronic camera. By removing the light source from the tip, the diameter of the tip may be further reduced to allow the space of the ear canal to be shared between the otoscope and a tool such as a curette for removing foreign objects or to permit the tip to navigate around ear obstructions. The sleeve may provide for multidirectional illumination of the ear structure for improved visualization. The tip and sleeve may be flexible for increased patient comfort when using a compact tip design.

The invention discloses a novel ophthalmologic examination head fixing device which structurally comprises a head fixing frame, a base and an examination apparatus. The examination apparatus is mounted on the base, the head fixing frame is arranged at the front of the examination apparatus, the bottom of the head fixing frame is connected to a side surface of the base, the head fixing frame comprises a support column, a fixing frame, a nut, a lifting rod, a chin fixing seat, left and right fixing frames, perforated holes, a forehead cushion and fixture blocks, a transverse rod of the L-shapedsupport column is arranged at the bottom of the support column, the support column is connected with a side surface of the base, an end of the vertical rod of the support column is connected with themiddle of the bottom of the fixing frame, and the end of the vertical rod and the middle of the bottom of the fixing frame are of integral structures. The novel ophthalmologic examination head fixingdevice has the advantages that each of the left and right fixing frames comprises a fixing sheet, a guy rope and an arc-shaped block, accordingly, the novel ophthalmologic examination head fixing device is simple in structure, convenient to manufacture and low in cost, can be replaced at any time and is easy to operate, and users can easily master the novel ophthalmologic examination head fixing device; the arc-shaped blocks in arc-shaped designs can cling to ear structures of human bodies, accordingly, good fixing effects can be realized, and patients can be prevented from swaying in the left-right directions.

The present invention proposes a reflector and difference network antenna. The antenna includes a reflector antenna, a feed source and a sum-difference network, the feed source is connected to the sum-difference network, wherein the feed source adopts a monaural horn, and two or more monaural horns are symmetrically distributed in pairs at the focal point of the reflector antenna. Both sides; the single-ear horn is in the shape of a pyramid horn, and the edge of the bell mouth is extended with a single-ear structure. The novel reflector and difference network antenna proposed by the present invention provides an effective solution for the occlusion of the reflector antenna by the feed source, and can obtain high gain, Low sidelobes, low null depth and highly symmetrical sector and difference beams.

The plant growth regulator for breeding rice hybrid consists of methoxone sodium 40-60 wt%, 2, 4-D 5-10 wt%, aspirin 5-30 wt% and starch 5-10 wt% mixed together. Into the plant growth regulator, triazolone in 35-40 wt% may be also added. The plant growth regulator has the functions of promoting the elongation of section below the ear of the sterile line, improving plant structure and ear structure, promoting the sterile line to bloom concentratively, raising the blooming period, etc. and thus can save the consumption of gibberellin, raise the hybrid bearing rate and increase hybrid yield.
