Title: Hydrophilic stainless steel material
Inventor: NISHI TORU
IPC: B05D7/14
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To remove a defect of inferior wettability inherent in a stainless steel and to obtain a hydrophilic stainless steel material with high coating suitability by specifying the center line average height at the surface and also specifying Rkr showing the degree of the upper and the lower kurtosis with respect to the center line of a roughness curve. SOLUTION: In this hydrophilic stainless steel material, the center line average height Ra at the surface and the value of Rkr showing the degree of the upper and the lower kurtosis with respect to the center line of a roughness curve are regulated to 0.1-5.0μ and <=10.0, respectively. If the value of Rkr is in the above range, sharp peaks are properly arranged at the surface to prevent the cohesion of water and improve hydrophilic property. In addition, water retentivity as the ability of retaining water and flux on the surface is important for the improvement of coating suitability. It is necessary to limit Ra because water retentivity is influenced by the state of ruggedness of the surface.  Further, because the ability of retaining water is decreased when the surface is smooth (Ra is small), it is necessary to regulate Ra to a value in the above range in order to provide required water retentivity.

Filed: 1987-10-29
Abstract: PURPOSE:To obtain the titled form with high electrical conductivity and low Shore hardness, by kneading carbonaceous powder with a benzylic ether-type phenolic resin followed by heat treatment of the resulting form in a non- oxidative atmosphere. CONSTITUTION:First, 100pts.wt. of carbonaceous powder is kneaded with 10-50 pts.wt. of a benzylic ether-type phenolic resin followed by injection molding or extrusion of the resulting product into a form.

Title: Optometric device
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/10
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To execute automatic optometry by controlling easily the angle of each target. SOLUTION: In the beginning, the flattest meridian angle, visual degree, and stripe visual acuity are determined. In an objectively measured flattest meridian visual degree and its angle, targets 5 of vertical stripes which are differently pitched are presented sequentially, and a subject S is asked to respond by a response means 4 by answering whether he can see the stripes or not, and his visual acuity is determined from the smallest stripe pitch which he answered he could see. Visual acuity is obtained by changing sequentially the angle of rotation of the target 5 slightly in both directions at that diopter scale. The angle to be changed depends on the degree of objective refractometric astigmatism, and if the degree of astigmatism is high, it is 5 to 10 degrees and the degree of astigmatism is low, it is 10 to 20 degrees.  From visual acuity measuring points corresponding to three angles, the relations are obtained by operation, and the resultant peak angle and visual acuity becomes refractive power and stripe visual acuity with the subjective flattest meridian.
