Patent JP-S6139224-A (JP)
Title: Magnetic recording medium
Inventor: IDE TOSHIAKI
IPC: C09D127/04
Filed: 1984-07-31
Abstract: PURPOSE:To decrease the chipping of a back coat by using the back coat layer contg. carbon black contg. ash content at a higher rate. CONSTITUTION:The back coat layer contains the carbon black having 2.0-45% ash content, 40-300m<2>/g specific surface area, 50-200ml/100g oil absorption rate and 10-50mum average grain size. The chipping of the back coat is liable to arise if the ash content in the carbon black is <2%. The dispersibility is poor and the surface roughness is low at >=45% ash content. The more preferable range of the ash content in the carbon black is 2.0-30%. The chipping of the back coat is thus improved and particularly the wear resistance of the back coat surface during high-speed running is improved.

Title: Apparatus for producing thin-walled metallic strip
Inventor: SATO HIROAKI
IPC: B22D11/06
Filed: 1984-07-31
Abstract: PURPOSE:To prevent the cooling of a molten metal and to produce a thin metallic film having uniform material quality in the stage of producing the thin metallic film from the molten metal by a cooling drum under rotation by providing a heater and cap to a gate contg. the molten metal. CONSTITUTION:The cooling drum 1 which rotates toward an arrow direction around the horizontal shaft and is internally cooled with water is installed in proximity to one side face of the gate 2 consisting of side walls 2b, 2c, a bottom wall 2a and a cap 2d at the top wall provided with a nozzle 7 for pouring the molten metal. The molten metal poured from the nozzle 7 into a pouring basin 3 for the molten metal sticks and solidifies in the form of the thin metallic film 4 to the outside circumferential part of the drum 1 under rotation and is thereafter stripped from the drum 1 by a scraper 5, by which the thin metallic film is continuously produced. The heating element 8 such as electric heater is embedded to the side walls 2b, 2c and the bottom wall 2a of the gate 2 in this case by which the heating of the molten metal is made possible. The radiational cooling of the molten metal is prevented by installing the top wall 2b. The thin amorphous or ultrafine crystalline metallic film having always the uniform material quality is thus continuously produced.

Title: Method for controlling oil film thickness in static pressure bearing for backup roll of rolling mill
Inventor: KANAO YASUHIKO
IPC: B21B37/62
Filed: 1988-06-29
Abstract: PURPOSE:To prevent plate thickness variation and to reduce the pump driving power by detecting an oil film thickness in a static pressure bearing, comparing the film thickness with a standard thickness, and controlling a supply amount of high pressurized oil based on the deviation value found by the comparison. CONSTITUTION:A non-contact displacement gage 24 is mounted on a bushing 4 of a static pressure bearing for a backup roll 1 and a servo motor 26 for supply amount adjustment of a high pressurized oil supply pump 12 and an oil film thickness gage setter 27 are also installed. A required oil film thickness is previously set by the setter 27 and an actual oil film thickness during rolling is detected by the gage 24. Then, a deviation of the detection value of the oil film thickness from the standard oil film thickness by the setter 27 is found and a high pressurized oil supply amount of the pump 12 is adjusted through the motor 26 according to the deviation amount. Thus, an oil film thickness in the bearing is kept constant under a rolling load changing condition. Therefore, plate thickness variation is prevented and the driving power of the pump 12 is reduced.

Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To improve an access time by activating a write recovery signal and delaying an active state of a precharge external signal when the precharge external signal is input during a write operation. SOLUTION: In a high state of a write recovery signal WR, an NMOS transistor N1 of a precharge signal output part 10 is turned ON. When a precharge signal PCG is input high, a PMOS transistor P1 is turned OFF and an NMOS transistor N2 is turned ON. N3, N4 are turned ON and, an ND5 is turned ON. The state is held for a fixed time by inverters INVs 7, 8. When the external PCG signal is input during a write operation, the WR is activated thereby to delay an active state of the PCG. In this manner, a time from a precharge time to an active time is reduced, so that an access time is improved.
