Title: Hard carbon thin film and its production
Inventor: HIRANO HITOSHI
IPC: C30B29/04
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To improve adhesion of the thin film to a substrate, or the like by forming a gradient structure of the thin film, such that the (sp<2> bonds)/(sp<3> bonds) ratio (sp<2> /sp<3> ratio) values of constituent carbon atoms of the thin film are gradually decreased in the direction from the substrate side to the surface side of the thin film. SOLUTION: Generally, the sp<2> bonds of carbon atoms exist in graphite and the sp<3> bonds of carbon atoms exist in a diamond and also, the sp<2> and sp<2> bonds of carbon atoms coexist in diamond-like carbon. In this thin film, the sp<2> /sp<3> ratio of the constituent carbon atoms is changed so as to be decreased in the thickness direction, to improve adhesion of the thin film to a substrate the like. The sp<2> /sp<3> ratio preferably includes values in the range of 0 to 3. That is, such a state that in the surface of the thin film, no sp<2> bond exists and only the sp<3> bonds exist, is included and at this time, the surface of the thin film has high film hardness and large internal stress. Also, on the substrate side of the thin film, the sp<2> bonds are increased to reduce the internal stress and to improve the adhesion to the substrate.  This hard carbon thin film is preferably formed by a plasma CVD (chemical vapor deposition) method, while e.g. changing the kinetic energy of ion species in a plasma so as to change the sp<2> /sp<3> ratio with film formation time.

Title: Method for controlling transportation of steel pipe
Inventor: KUBO KISHIO
IPC: C21D11/00
Filed: 1990-09-27
Abstract: PURPOSE:To maintain the spacing between steel pipes in a post-stage heat treating furnace at a specified spacing by determining a high-speed transporting length and fixed-speed transporting length from the lengths of the steel pipes and maintaining the time required from the start of extraction of the steel pipes from a front-stage heat treating furnace before charging of the steel pipes into the rear-stage heat treating furnace at the specified period of time. CONSTITUTION:The two heat treating furnaces 1, 2 disposed in parallel are connected in series to execute the heat treatment of the steel pipes 6. The lengths of the steel pipes 6 extracted from the front-stage heat treating furnace 1 are detected at this time and the high- speed transporting length and fixed-speed transporting length are determined in accordance with the detected steel pipe lengths. The steel pipes are transported at the high speed for the high-speed transporting length determined at the point of the time when the steel pipes arrive at the charging table 5 of the rear-stage heat treating furnace 2 so that the time required from the start of the extraction of the steel pipes from the front-stage heat treating furnace 1 before the completion of the charging of the steel pipes into the rear-stage heat treating furnace 2 is maintained always constant. (L-L1)/V1+L1/V2=fixed time; where L: the steel pipe length (m), L-L1: the high-speed transporting length (m), L1: low-speed transporting length (m), V1: the high-speed transporting speed (m/min), V2: fixed-speed transporting speed (m/min). The collision of the steel pipes against each other on the charging table 5 is prevented in this way in spite of a fluctuation in the length of the steel pipes to be treated. In addition, the spacing between the preceding steel pipes and the succeeding steel pipe in the rear-stage heat treating furnace 2 is maintained nearly at the fixed spacing like the front-stage heat treating furnace 1.

Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To suppress that a natural oxide film on a wafer placed on an area whose temperature is high owing to heat from a heat treatment furnace in a transfer room. SOLUTION: The transfer room 2 is divided into a first area S1 and a second area S2. An intermediate delay stand 23 and a wafer port 24 are provided in the area S1 and a transfer arm 26a transferring the wafer in a cassette 7 to the intermediate delivery stand 23 is provided for the area S2. A first ventilation path 61 is provided for the area S1 and a second ventilation path 62 is provided for the area S2. Then, gaseous nitrogen is circulated in the respective areas by the ventilation paths 61 and 62 in a direction vertical to a side wall 22a so as to conduct it. When the flow velocity of gaseous nitrogen in the area S2 is made slower than that in the area S1, a boundary is made between the areas S1 and S2.  Oxygen diffused into the area S2 from the cassette 7 cannot go over the boundary and it is not diffused into the area S1 and therefore the formation of the natural oxide film of the wafer in the pertinent area is suppressed.

Title: Wear resistant carbon roll and its production
Inventor: HIROTA YOSHIAKI
IPC: C04B41/50
Filed: 1993-09-27
Abstract: PURPOSE:To prevent the thermal crown of the roll to be used for transporting, cooling and direct electrical heating of a metallic strip and to improve its wear resistance. CONSTITUTION:A wear resistant film 4 of TiN or TiC is formed on the surface of the carbon roll or the particles of the TiN or TiC are dispersed into base material carbon. A metal oxide is packed into the fine pores of the base material carbon. As a result, the thermal crown for a high thermal conductivity and low coefft. of thermal expansion is prevented and the deformation and temp. nonuniformity of the steel sheet are prevented. The generation of sparks arising from a contact defect is prevented and the wear resistance is improved as well even in the case of using of the roll as an energizing roll. The long-term stable use of the roll is thus possible and its oxidation resistance is sufficient.

In the 1st period, the data are transferred based on a half-speed protocol followed by the program instruction that is read out of a relative ROM 602. In the same way, a buffer where a full-speed period is exclusively supplied to an area 603A of a RAM is supported while a program instruction is read out of an area 603B of the RAM. A switching period is secured between two processing modes while the old data are processed based on the half-speed protocol. At the same time, the new data are processed based on a full-speed protocol.
