Abstract: An exploration method according to the present disclosure includes: a step (S11) of disposing, in a pipeline (PL) that allows a plurality of manholes (MH) to be interconnected, an electromagnetic wave receiving/transmitting device (1) that transmits an electromagnetic wave and receives a reflected electromagnetic wave that is a reflected wave of the electromagnetic wave; a step (S13) of transmitting the electromagnetic wave; a step (S14) of receiving the reflected electromagnetic wave that is the reflected wave of the electromagnetic wave; and a step (S18) of calculating an intensity distribution of the reflected electromagnetic wave on the basis of an intensity of the reflected electromagnetic wave and a round-trip propagation time from when the electromagnetic wave is transmitted to when the reflected electromagnetic wave is received.

Abstract: A skin sensitivity improving agent which is safe and, when routinely taken or applied to the skin, exerts an effect of improving deterioration in peripheral sensation is provided. The present invention also provides a food, a drink, a feed or a cosmetic for improving sensation which exerts an effect of improving deterioration in peripheral sensation when orally taken or applied to the skin. The skin sensitivity improving agent includes, as the active ingredient, a basic protein fraction derived from milk or a degraded basic protein fraction derived from milk. By orally taking the basic protein fraction derived from milk or the degraded basic protein fraction derived from milk or applying the same directly to the skin, deterioration in sensation, in particular, peripheral sensation can be improved. Thus, a food, a drink, a feed or a cosmetic for improving sensation can be obtained.

Abstract: A method for the production of a glass substrate for magnetic recording mediums is herein provided and this method is characterized in that the final cleaning step is performed in two stages, in which scrubbing and dip-cleaning steps are carried out after the completion of the first cleaning stage and after the growth of needle-like projections comprising an alkali metal carbonate on the surface of the glass substrate. The method for the production of a glass substrate for magnetic recording mediums does not require the use of an expensive device having high resistance to acids. Moreover, in the glass substrate for magnetic recording mediums produced by the foregoing method, any growth of needle-like projections containing an alkali metal carbonate on the surface of the glass substrate is inhibited even during temporal storage of the substrate.

Abstract: A sealing ring assembly comprises a synthetic resin sealing ring body having two opposing stepped cut surface portions including respective planer portions in sliding contact with each other, a synthetic resin gas sealing ring in contact with the inner circumferential surface of the sealing ring body, and a metal ring in contact with the inner circumferential surface of the gas sealing ring. To prevent the stepped cut surface portions from sticking to each other at the planar portions thereof, a metal film layer is provided on a planar portion of one of the stepped cut surface portions.

Abstract: A rod seal device for a Stirling engine includes a piston rod connecting operating piston and a guide piston latter being served as a power take-off device, various seal members disposed between the two pistons and surrounding the outer peripheral portion of the rod. The seal device further includes a plurality of chambers disposed around the outer periphery of the rod between a working chamber of the engine and a working chamber of the power take-off for discharging any gas leaked therefrom or preventing any undesired mixture of the two different working gases.

Abstract: A rod seal device for a Stirling engine includes a high pressure oil chamber, an oil seal, and a low pressure oil chamber in series disposed between a compression chamber of the engine and a driving unit of power take-off. The oil seal includes an annular slit open to one end of the low pressure oil chamber for scraping oil from low pressure oil chamber to the high pressure oil chamber.
