Although γ-ray surveys have often been carried out in order to research active faults, clear correspondence of γ-ray intensity to faults has not always been obtained. We examined over again the methods of γ-ray surveys and the following two points came up as important problems.(a) The hole to set the senser of γ-ray survey meter must be bored in the same radius and depth at each survey point.(b) Much attention must be payed to the difference of surface materials.In order to confirm the usefulness of the method in which the above two points are taken into consideration, the γ-ray surveys were carried out along a line across the Himenoyu fault. This fault was formed at the time of North-Izu earthquake in 1930, and its traces are yet clearly found. A clear peak of γ-ray intensity was obtained at the position on the fault.Next, this method was applied to the Ono fault whose precise position has not yet known, and we estimated the position of the fault by the results of γ-ray surveys.

The purpose of this study was to investigate if a volleyball player could change the course of the spike by a signal given at various stage in spiking motion, and to find the differences of the spike form on these conditions. Conditions were to make a full swing spike toward a cross course and to change the spike course toward a straight course when signal was shown. All of spike motions were filmed and analyzed. Points of view for analyzing are following : a) Initial velocity of the ball. b) Maximum velocity of the finger. c) Body angle to the direction of running. d) Direction of spiking hand after striking the ball. Results of these experiments indicates that : 1) If the signal was switched on just before the beginning of the forward swing in spiking, all subjects could change the spike course on most occasions. On this study, "just before the beginning of the forward swing" meant about 0.30 to 0.35 seconds before the beginning of the forward swing. 2) Initial velocity of the ball, on the case when the signal was given just before the beginning of the forward swing, was later than ones on the another cases. 3) However, the finger velocity of this case was faster just before meeting to the ball. 4) There were no significant differences on the body angle to the direction of running jump at the various spike motions. 5) Directions of the arm after spiking the ball was decided depending on the course of the spike.
