Inventor: IIJIMA SUMIO
IPC: C23C16/26
Filed: 1990-09-25
Abstract: PURPOSE:To obtain a homogeneous diamond thin film having a smooth surface by applying ultrasonic waves to a diamond powder suspension layer placed between a substrate and a vibration plate to pulverize the diamond powder and embed the formed diamond fine powder into the substrate, and subsequently forming a diamond thin film on the seed-embedded substrate. CONSTITUTION:The suspension of diamond powder having a particle diameter of >= sub-micron unit is held between a substrate 3 and a vibration plate 2 vibrated by ultrasonic waves. Ultrasonic waves from an ultrasonic wave generator 1 are applied to the suspension to pulverize the diamond powder, thereby permitting to embed the formed diamond fine powder having particle diameters of <= several ten nm into the surface of the substrate 3.

Title: Light wave interference length measuring instrument
Inventor: ISHIDA AKIRA
IPC: G01B9/02
Filed: 1987-10-12
Abstract: PURPOSE:To find a real length measured quantity in real time by finding length measurement data on the same object by light wave interference by using two different wavelengths and removing an error in length measurement calculated with said data and dispersion characteristics of the air by a signal processing means. CONSTITUTION:Luminous flux from a light source (Ar laser) 7 is split into two by a polarization beam splitter 6, S-polarized light is reflected and retroreflected by a fixed mirror 2, and P-polarized light is retroreflected by a moving mirror 1 as it is while the remainder is converted into a 2nd higher harmonic of the S-polarized light and retroreflected. Then its basic part is transmitted through a mirror 10 and the 2nd higher harmonic is reflected; and the P-polarized light reflected by the moving mirror 1 generates the 2nd higher harmonic of the S-polarized light again through the optical system 8. The variation term of interference fringes by the beam splitter 11 indicates a difference in phase variation due to fluctuation of the air. The P- polarized light which is not converted by the optical system 8, on the other hand, has its phase variation found from the S-polarized light from the fixed mirror 2 and interference fringes by the beam splitter 13. The displacement measurement quantity of the moving mirror 1 is obtained by the arithmetic processing of a signal processing system 5 while an error due to the fluctuation of the air is removed.

Filed: 1994-10-20
Abstract: PURPOSE: To enable the separation of three kinds of cokes in one cooling chamber of a shaft kiln type by switching the destination of transport of a specific kind of coke, another kind of coke, and their mixture. CONSTITUTION: After a cooling chamber 1 is confirmed to be completely filled with coke A (a level meter 13 being on), coke B is charged into the chamber 1 and then the mixing of coke A with coke B is started. After T2 hr calculated by a calculator has elapsed, a switching damper 4' of a branched chute 10' is switched to transport the mixed coke to a hopper 6 for the mixed coke. When T3 hr calculated for coke B to completely fill the chamber 1 has elapsed, the switching damper 4 of the branched chute 10 is switched to tranport coke B to a hopper 7 for coke B. Since the mixing ratio of coke A with coke B can arbitrarily be changed by adjusting the timing of damper switching, an allowable mixing ratio of different kinds of coke can be obtd. by changing e.g. t2 to t'2 or t3 to t'3 .
