This paper deals with the experimental research on the effects of change of wire drawing condition on hardness distribution over the section of drawn wire.Using a Micro-Vickers hardness tester, we tried to investigate the hardness distribution over the cross section of three kinds of carbon steel wires and a brass wire, drawn under several kinds of drawing conditions, as well as the gradual change of hardness over the longitudinal section of carbon steel wires under plastic deformation with half drawn specimen.As the results we have make it clear that the wire with uniform deformation as possible will be obtained by following methods of drawing:(1) with the die of larger radius of curvature of drawing surface than with the die of smaller radius, (2) under high reduction of diameter than low reduction.

Hevea stocks have been used to produce vibration isolators but recently they are using many synthetic rubbers. Each of them has its own merits and demerits, so by vibration tests we intended to explain and compare their characteristics employing hevea stock F.A.Q. No. 3, neoprene G.N.-A., hycar-OR-25 and silicone, so that we may obtain data to decide what sort of rubber should be used to design isolators.The followings were examined: (a) influence of temperature, (b) amplitude dependency, (c) oil resistancy, (d) after effect, and (e) others.

Rheological analysis of "body" or consistency of "yokan" (pasty food made from gelation of concentrated starch suspension in sugar solution by agar-agar) was done by using a curdometer. Thirty samples of yokan from various makers were tested. As a first step, they were classified into three groups, i.e., good, medium, and poor, according to their practical evaluation, e.g., "body", stiffness or consistency. The curdometer used was a modified penetrometer. A small circular disk is pushed into the sample paste by means of a spring. Penetration of the disk is recorded on a drum. From observation of the recorded curves, it is possible to evaluate elastic deflection, plastic yielding or viscous flow of the paste. High grade yokan of good body is characterized by high viscosity and a sort of strain-hardening. Yokans of poor body, on the other hand, show continuous flow after plastic yielding. Their mechanical properties were compared with their compositions and chemical constituents. Sufficiently high value of starch and sugar content is necessary for the appearance of good body. Rheological data, so acquired and properly analysed, were used effectively in the design of a continuous processing plant of yokans.

Experiments have been made with two kinds of O/W type emulsions. Compositions of the emulsions are shown in Table 1. The flow properties of these emulsions and their dispersion mediums have been studied in the range of low rates of shear. Effect of the flow properties due to addition of salts or lower alcohols are also observed. The two kinds of emulsions stated above, reveal different behaviours under shearing stress. One of them (emulsion I) reveals the Newtonian flow in the range of low dispersion concentrations. The other (emulsion II) behaves as the non-Newtonian fluid over all the range of concentrations. In the former, the dispersed particles may retain the dispersion state comparatively similar to that in the case of the static condition and this structure may be destroyed under shearing stress. This difference may be caused by the difference in the thickness and character of the hydration layer of the particles. These results may be well explained by assuming that the thickness and the character of hydration layer depend on the kind of the hydrophilic group of the emulsifying agent.
