Filed: 1985-08-26
Abstract: PURPOSE:To facilitate the measurement of a N-value (the impact number of times required in the penetration of a constant length), by automatically performing the falling of a hammer only by the control of compressed air. CONSTITUTION:When the valve 49 of a change-over valve 10 is opened and the valve 50 thereof is closed by the order from a microcomputer, compressed air is supplied from a supply port 12 and control valves 26, 27 are fallen against a spring 28 to close a transverse hole 32. At the same time, compressed air is supplied to a lower surface chamber 23 from the lower hole 22 of an air guide pipe 18 through an orifice 30 and a hammer 9 rises to exhaust air of an upper surface chamber 24. When the hammer 9 reaches the uppermost point, a plunger 37 is pushed up and a change-over switch 11 is operated and the valve 49 is closed while the valve 50 is opened. Because of this, the supply of air is cut off and the control valve 26 rises by the string 28 to open the transverse hole 32. Because air of the lower surface chamber 23 reversely flows through a pipe 18 and passes through the upper surface chamber 24 from the transverse hole 32 to be communicated with the open air, the hammer 9 falls freely in a cylinder 7. The impact of the hammer 9 is transmitted through a bottom plate 8 and a sampler is driven into ground. This operation is repeated to measure a N-value.

Abstract: PURPOSE:To visually recognize the outline classification of the recorded information. CONSTITUTION:When a pit 1a is formed on an optical disk 1, an optical reflectance around the pit formed in the character region 13 corresponding to the shape of character representing the outline classification of the recorded information is made to the different one from optical reflectances around the pits formed in other regions by changing the intensity of a laser beam. Then, the character representing the outline classification capable of visually recoginzing by the character region 13 with different optical reflectance is displayed. Then, the outline classification of the recorded information can be recorded in the state capable of recoginzing at the same time when the information is recorded, therefore, the process for displaying the classification is omitted and also the outline classification of the recorded information is easily discriminated even at the time right after the information is recorded.
