摘要:
An improved aqueous coating composition for the production of cast coated paper is disclosed. The pigment component of the coating contains at least 5% by weight of cubic calcium carbonate having a mean particle size of 0.1 to 1.0 micron. When this coating composition is used the operating speed of the cast coating process is remarkably improved and a cast coated paper having excellent whiteness, gloss and printability is obtained.
摘要:
A method of producing cast coated paper in which a rewetted or gelled coating layer is pressed at a linear pressure of above 120 kg/cm against the highly polished finishing surface of a cast coating drum having a surface temperature of above 90.degree. C. Improved cast coating operations are secured by including in the coating composition and/or in the rewetting liquid or the gelling liquid, a releasing agent selected from the group consisting of a phosphate having a fatty hydrocarbon radical with 6 to 22 carbon atoms, an amine-salt thereof and lecithin.

摘要:
A disk drive housing structure has a rotating disk for recording information and a transducer adapted to write and read information on and from the disk. The structure further includes a positioning system having at least an arm to which the transducer is fixed and which is adapted to selectively position the transducer along the radial direction of the disk transducer by turning the arm. The structure also includes a member on which the disk, transducer and positioning system are mounted, wherein the mounting member includes a first housing which supports thereon both ends of a rotary shaft of the recording medium and both ends of a rotary shaft of the positioning system, and which has a first aperture part. The first housing further includes a second aperture part through which the disk and the rotary shaft supporting the disk are inserted and to which a supporting member for the rotary shaft of the recording medium is fixed.
摘要:
A magnetic disc head positioning system using a stepper motor eliminates positioning errors due to different approach directions and distances to a target track position through a drive control of temporarily stopping the head at a position immediately preceding or following the target track depending on the approach direction and, thereafter, moving the head from this position to the target track with a constant transient response. The head is brought to the temporary stop position by utilizing the overshooting response of the stepper motor so as to minimize the positioning time.
摘要:
A control means of a molding machine is designed so as to control molding cycles SA and SB for sequentially performing injection of molten resin into a product portion of a mold 1 to fill it therewith, cooling down and solidification of the filled molten resin, mold opening of the mold 1, taking-out of a molded product, and mold closing of the mold 1 as well as changing the shape of a molten resin filled region of the product portion in accordance with the shape of a molded product to be molded in the next molding cycle during the present one molding cycle. Therefore, it is possible to change the shapes of molded products without the need to stop the molding cycle.
摘要:
A magnetic disk apparatus has a disk assembly including a single servo disk and a plurality of data disks, a servo-head supporting structure for supporting a servo head and data-head supporting structures for supporting data heads. These heads are so disposed as to cooperate with respective disks. The servo-head and data-head supporting structures are driven by an actuator to move the servo head and the data heads to the required positions on the corresponding disks. The servo-head supporting structure and each of the data-head supporting structures have different proper oscillations to prevent the occurrence of a resonance during a seek operation.
摘要:
A braking device for arresting an axial relative movement between a bearing, and a shaft slidably engaging the bearing and extending through a cylinder which is axially immovable to the bearing. The device comprises: an annular piston slidably received in the cylinder and slidably engaging the shaft; a brake shoe engaging the shaft axially immovably relative to the cylinder and radially contractible to apply a brake to the shaft; a resilient radial clamp member engaging the outer surface of the brake shoe, axially compressible by axial movement of the annular piston and thereby reduced in inside diameter to force the brake shoe against the surface of the shaft; and a piston driving device for moving the shaft along its axis through a controlled selective supply of a pressurized fluid to the cylinder. The piston driving device may comprise a coil spring to bias the piston to cause an axial compression of the radial clamp member, and a device for effecting the controlled supply of the fluid. The shaft may be normally arrested or released by appropriate arrangement of the piston driving device.
