Title: Method for monitoring carbon film of optical fiber
Inventor: SHIMOMICHI TAKESHI
IPC: C03C25/42
Filed: 1990-09-06
Abstract: PURPOSE:To continuously measure the quality of the carbon film formed on a bare optical fiber without contact by measuring the film quality of the carbon film from a change in the dielectric loss of the resonance frequency region of the optical fiber 1 on which the carbon film is formed. CONSTITUTION:The bare fiber of the optical fiber on which the carbon film is formed is inserted into a coil in which a high-frequency current flows and the quality of the above-mentioned carbon film is measured from the change in the dielectric loss of the resonance frequency region. The reasons thereof are as follows: Since the electric conductivity of the carbon film occurs in the orbital of the pi electrons existing in the Z-axial direction of a graphite type crystal structure, the electrical conductivity in the horizontal direction of the crystal is better as the degree of crystallization of the graphite is larger and the orientability of the two-dimensional graphite crystal is larger. Since the electric conductivity of the amorphous carbon film occurs in the orbital of the pi electrons, the change in electric resistance appears as a change in the dielectric constant as well and the orientability of the two-dimensional graphite crystal appears in the form of the dielectric loss.

Title: Water bottom covering material
Inventor: ISONISHI MINORU
IPC: E02B3/12
Filed: 1998-08-08
Abstract: PROBLEM TO BE SOLVED: To improve handleability of a covering material by forming it into an irregular shape almost the same with the upper face of a concrete block. SOLUTION: A covering material 1 for water bottom is water-resistant and it is formed of a material having an affinity for algae or aquatic creatures. When a concrete product is to be manufactures, the covering material 1 is formed to have almost the same shape with irregularities on the upper face of a concrete block 2 and put on the concrete block 2. In a method in which the covering material 1 is used as a molding form for the concrete block 2 and concrete mortar is poured therein, since the covering material 1 is closely stuck on the concrete block 2, an effect that both are mutually reinforced is brought out. Accordingly, there is less possibility that projections of the concrete block are chipped off when handling it, and also there is less possibility that the covering material is ruptured while using it.

Title: Image forming device
Inventor: NOGUCHI KAZUNOBU
IPC: G03G21/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To equalize the degree of the deterioration of the image carrying force of a center part and both side parts and to obtain a good-quality reproduced image by accumulating and holding the number of times or the time of image forming operation and moving an image carrier in a direction nearly orthogonal to the carrying direction of a recording sheet by a specified amount when parallel image forming information satisfies a fixed condition and image forming is not executed. SOLUTION: A photoreceptor moving time decision part 160 counts the number of copying times in a parallel carrying mode, and decides timing so that a photoreceptor drum 45 may be moved when the counted value is equal to or above a specified reference counter value and copying operation is not hindered. When a CPU 110 decides an edge where flip-flop output from the decision part 160 falls from an H level to an L level, it designates a photoreceptor moving motor driving part 150 to normally rotate a motor 454 so as to move the photoreceptor drum 45 to an inner side. Since such operation is executed whenever an H level signal is transmitted, an image forming area on the photoreceptor drum 45 is nearly periodically moved.

Abstract: PURPOSE:To prevent over rich of air-fuel ratio, by reducing acceleration fuel increment rate when an engine is changed to accelerating operation immediately after decelerating operation. CONSTITUTION:In a controller 28 for a fuel injection valve 11, a basic injection quantity operating circuit 30 operates a basic injection quantity based on signals fed from an air flow sensor 21 and a rotation sensor 24.
