Ab st ra ct Hologram image is so realistic that various images can be displayed at stereoscopic image in three dimensional space even though they are illusion. The main subject of this paper is to express the meaning of our existence using the hologram image. We succeeded to present the memory of human life such as feeling of happiness, brightness and silence of our life by a series of hologram works of "A memory of a Stone" using the pulse laser holographic image and made clear the efficiency of this method. A stone named "Sand Rose" is the symbol of our self-existence.

Part I: The measurement of the carding torque which appears at the shafts of the workmg rolls during their operation was studied by transforming the carding torque into an electric potential using a strain gauge. This article will discuss the design of the strain shaft which senses the carding torque properly, the steps for obtaining the true signal, and the experimental results which clarify the reliability of the measurement.Part II The factors which affect the carding torque of a particular fiber stock are. (i) the type of fiber and the degree of fiber entanglement ; (ii) the rate of feed; (iii) the relative speeds of the rollers and the gauge.In this report the first two factors were investigated, and the carding coefficient was determined. This coefficient is proportionat to the torque required to card one gram of fiber stock, and its value is dependent upon stock conditions, e. g., fiber orientation, length, linear density and the type of fiber.'
