A cowl (136) for an aircraft engine (10), and processes for producing the cowl (136) to have a layered construction and a high temperature capability. The layered construction of the cowl (136) includes a core member (144) having a cellular construction comprising internal hollow cells (148), and first and second skins (140,142) brazed to edges (152) of the cells (148) at opposite surfaces of the core member (144). The first and second skins (140,142) and the core member (144) are formed of titanium alloys, the first and second skins (140,142) are brazed to the core member (144), and the layered construction of the cowl (136) lacks a thermal insulation capable of thermally protecting the second skin (142) and brazed joints (150) that attach the second skin (142) to cell wall edges (152) at the second surface of the core member (144).

The invention discloses a reserved sleeve joint bar positioning device for a PC building wallboard. The device comprises a working table and a supporting box. The structure is simple, and mounting andlater equipment regular inspection are facilitated; a groove and a sliding rail are arranged, a clamping device on a moving plate is conveniently driven to move, thus a sleeve can be mounted at the accurate position through a fixing groove, and the problem that the manual operation precision is not high is solved; a buffer block and a spring are mounted, the durability of a supporting frame is improved, and the stability is good during working, and deflection is avoided; a rotating block is arranged, the position gap of a clamping block is conveniently adjusted, and the sleeve is convenientlyand accurately positioned; a protective layer is arranged, thus the sleeve is not abraded, and the service life of the clamping block is prolonged; a positioner is arranged, the position of the sleeve is conveniently positioned, and the accuracy is improved; and a loudspeaking hole is formed, an operator is conveniently reminded, if an error occurs, working is conveniently stopped in time, greater loss is avoided, the cost is reduced, and the practicability is improved.

The invention relates to a breast electrical impedance fault imager based on a mobile phone platform, belonging to the technical field of medical detecting instruments and biological detection. The fault imager comprises a breast detection component, an electrical impedance detection circuit and a mobile phone comprising data result display and analysis software, wherein the electrical impedance detection circuit comprises a singlechip, a frequency generator, a filtering amplifying circuit, an analog switch, an electrode group and an amplitude phase detection chip. The invention can make patients periodically checked and early diagnosed without going to hospitals and particular working environments by adopting a biological electrical impedance fault image detection technology and widely used mobile phones, and a personal medical record library can be saved so as to exchange with doctors in time and check patient's conditions. The imager has the characteristics of small volume, high safety, simple operation, low cost and the like and is especially suitable for household use.
