Title: High pressure gas transferring apparatus
Inventor: MATSUDA MASAHARU
IPC: F17C13/00
Filed: 1980-03-28
Abstract: PURPOSE:To improve the safety of transferring a high pressure gas by automatically controlling the switching of opening and closing a large-diameter automatic valve depending on the difference in high and low pressure containers by means of the first transfer tube with the former valve and the second transfer tube with the latter valve between the two containers. CONSTITUTION:Difference in pressure between high and low pressure gas containers 1 and 2 with a differential pressure gauge 7 is inputted into a controlling circuit 8 and compared with a preset pressure. When the pressure exceeds the preset level, a small-diameter automatic valve 6 opens while a large-diameter automatic valve 5 closes according to a control signal. When it is below the preset level, the control signal is inverted and the small-diameter automatic valve 6 closes while the large-diameter automatic valve 5 opens. Thus, the pressure of a gas flowing into a low pressure container is automatically adjusted depending on the pressure difference between the two containers 1 and 2 thereby ensuring a safe transfer of a high pressure gas.

Filed: 1993-02-26
Abstract: PURPOSE:To obtain a skin external preparation capable of preventing the skin from aging by normalizing the skin function such as water holding ability of the skin or turnover of a skin keratinous cell layer. CONSTITUTION:This skin external preparation comprises a membrane-coating granule (MCG) as an active ingredient in an amount of 0.01-10wt.%, preferably 0.1-1wt.% in the preparation. The transepidermal water loss of the aged skin such as roughened skin or xeroderma is reduced by applying the MCG to the skin to restore the water holding function and further normalize the delayed turnover of the keratinous cell layer. Thereby, the skin can be improved into an excellent state thereof. The MCG is obtained as an extract separated from the mammalian skin with water or an organic solvent or a purified extract thereof. For example, the epidermis of the mammalian skin is peeled and the peeled epidermal cell is then ground to destroy the cell membrane. Precipitates of uncrushed cells or nuclei are subsequently removed by a method such as centrifugation to afford the purified MCG.
