Title: Formation of diamond film on si substrate by cvd method
Inventor: TAKI MASAYOSHI
IPC: C30B29/04
Filed: 1991-01-21
Abstract: PURPOSE:To form a diamond film by CVD method which can increase nucleus generating density and form the film having a flat surface. CONSTITUTION:After a polycrystal Si layer of 50-200Angstrom  crystal grain size is formed on the Si substrate, many difference parts in level which cause to start generation of diamond nucleus are formed on the surface of the Si substrate by etching specific surface of the polycrystal Si layer to form etch pits of 10-50Angstrom  in depth using crystal face anisotropic etchant. The diamond film is formed on the surface of the Si substrate by CVD method. As many difference parts in level which cause to start generation of diamond nucleus are formed on the surface of the Si substrate by forming the etch pits, nucleus generating density of the diamond remarkably increases compared with the conventional example as shown by fig. and at the same time the diamond film having a flat surface is obtained.

IPC: G02B6/46
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To make no optical fiber cable loosened even though such phenomena as a galloping, sleet jump, and wind vibration are generated in an overhead ground wire after an OPGW winding works, by providing in the OPGW winding machine a preforming apparatus of making the optical fiber cable deform plastically. SOLUTION: When a bobbin with a wound optical fiber cable 2 is rotated around an overhead ground-wire 3, a preforming apparatus 4 is also rotated simultaneously around the overhead ground-wire 3 to generate a spiral plastic deformation in the winding optical fiber cable 2 passing through the preforming apparatus 4. The optical fiber cable 2 is deformed plastically with a constant spiral inner diameter and at a constant pitch, and the optimum value of the spiral inner diameter is not smaller than 80% and not larger than 95% of the diameter of the overhead ground-wire 3. As a result, the distance between the post of the optical fiber cable 2 being wound around the overhead ground-wire 3 and the outgoing end of the cable 2 from the bobbin can be shortened.  Therefore, even through such phenomena as a galloping, sleet jump, and aeolian vibration are generated after the execution of the winding works, the optical fiber cable 2 is not loosened.

Abstract: PURPOSE:To obtain a highly accurate tread measuring device having high resolution, which can compensate for temperature without a complicated constitution, and wherein computation is performed by using the resistance values in correspondence with the width of the tires before the vehicle tires tread on a pressure sensitive conductive members and after the tires tread on the members. CONSTITUTION:Length measuring and converting devices are formed in perpendicular to the advancing direction of a vehicle by conductors 7; pieces of pressure sensitive rubber 8, whose loaded parts become conductive and short the corresponding parts of resistors 9; and the resistors 9 with a length l0. When one of said two length measuring devices, having a width of DELTAl, is trod, the resistance values R0 and R2 of the resistor 9 before and after the treading satisfy the relationship of the expression I , since the ambient temperature is regarded as constant within the passing time of the vehicle and the temperature conversion coefficient is constant. With respect to the other length measuring and converting device, the same relationship is satisfied. By using the measured voltages corresponding to the resistances R0, R2, and the like, computation based on the expression II is performed by a data processing device 16. Then, a temperature change is compensated in correspondence with the expression III, and a tread length L is deterined. Thus a highly accurate tread measuring device with high resolution, by which temperature can be compensated without complicated constitution, can be obtained. In the expressions, R2 is a resistance value corresponding to the length l2.
