Title: Insulating device for deep sea bottom sample sampling container
Inventor: TSUJI YOSHITO
IPC: G01N1/28
Filed: 1991-11-18
Abstract: PURPOSE:To enable a device to be light by creating a high-voltage air source by utilizing a water pressure of a sea bottom and then enclosing a mud sampler by forming a multiple air layer by introducing the compressed air to an air bag for insulation. CONSTITUTION:When a submarine reaches a specified sea bottom, a check valve 3 is opened due to the sea water pressure and sea water at the bottom of the sea flows into an air source tank 1. When the submarine rises to some extent after sampling a sample, a pressure of a surrounding sea water is reduced, thus enabling the check valve 3 to be closed, a high-pressure sea-water pressure of the sea bottom to be enclosed into the tank 1, and then air within an air bag 2 to be a high-pressure compressed air. The compressed air is allowed to flow to an air bag 9 for insulation through pressure-control valves 81-8n, thus enabling a mud sampler 10 to be enclosed with a multiple air layers for insulation. At this time, a setting pressure of the control valves 81-8n is set so that the air layer may be inflated from inside successively for reduction in pressure due to surfacing of the submarine, thus enabling each air layer to be uniform in thickness corresponding to a sea-water depth and an insulation effect to be improved. The tank 1, the air bag 2, etc., can be made of plastic, thus enabling the device to be light.

Filed: 1990-11-09
Abstract: PURPOSE:To enable simple and high precision measurement of wave length dispersion of an optical fiber by transmitting ultrashort pulses having the width of wide spectra through an optical filter of a variable band pass. CONSTITUTION:Ultrashort pulse light generated in an ultrashort pulse light generator 1 transmits an optical fiber 2 to be measured. Outgoing light passing this is branched with the use of a light branching unit 3, one light is transmitted through a variable optical band pass filter 4 and the other light is combined by a branching filter 6 after it passes a delay line. Light is converted into an electric signal with the use of a light sensor 7 and observed with the use of a pulse wave form observation device 8. The transmission wave length is changed with the filter 4 and on the other hand the relative delay time of two pulse lights as the reference light on a time axis is measured as a function of wave length to find a wave length dispersion value of the fiber 2 from its differential. Accordingly the measurement of high precision can be performed without any influence of optical path difference change caused by an external factor such as temperature change and the like.
