    Abstract: PROBLEM TO BE SOLVED: To provide a blow spin die apparatus enabling use of a short die without causing lowering of production ability. SOLUTION: This blow spin die apparatus has a distribution plate 10 and a slot die 20 with plural die chips 24 formed in which spun capillary 28 is formed. The capillary has a first opening which is made to communicate with the distribution plate and a second opening opened at the top of die chip. Two cheek plates 40 and 42 are arranged adjacently to both sides of the die chip and flow path 50 having opening adjacent to the top of the die chip is arranged therewith.

    Abstract: PURPOSE: To continuously and accurately measure the electric properties of rock formations by a simple method. CONSTITUTION: An orbital torsion vibrograph 10 is provided with a tubular housing 12 having a cap sleeve 14 which is tightly clamped to an upper sleeve 16 and the sleeve 16 is tightly clamped to an intermediate sleeve 18. The sleeve 18 is held in a bottom sleeve in a clamped state. For the vibrograph 10, a connecting ring 28 is connected to an inserted connector 38 by means of a screw post 32 and the ring 28 is provided with a double-conductor logging cable 30. A rotary mass body 34 is applied to the cap sleeve 14 so that the upper sleeve 16 may be coupled with the threaded end of the sleeve 14 and an actuation sensor 44 which can become an accelerometer or a geophone is supported on the mass body 34.
