Title: Production of hydraulic inorganic board
Inventor: KUBO MASAAKI
IPC: C04B28/02
Filed: 1988-03-26
Abstract: PURPOSE:To obtain a high-quality hidraulic inorganic board with high efficiency by adding a defoaming agent to a slurry of a cement based matrix material and fiber reinforcing agent and forming a board therefrom. CONSTITUTION:A cement based matrix material and a fiber reinforcing material consisting of pulp and/or asbestos are formed into a board and produce a hydraulic inorganic board. In the process, a defoaming agent is added to a slurry of the cement based matrix and fiber reinforcing material. Portland cement, portland cement granulated blast furnace slag, portland cement-fly ash or portland cement-granulated blast furnace slag-fly ash are used as a suitable cement matrix material. A defoaming agent normally used in a paper sheet forming process, such as wax emulsion based defoaming agent, protonic defoaming agent or silicone emulsion based defoaming agent, etc., can be used as the defoaming agent.

Inventor: WATANABE MAKOTO
IPC: G11B5/60
Filed: 1987-03-27
Abstract: PURPOSE:To prevent a slider from being inclined and to attain stable magnetic recording and reproducing by constituting a magnetic head so that a fixing position between a flexible pattern cable (FPC) and a gimbal is set up vertically to the rotating direction of a medium and allowed to coincide with the center of the slider. CONSTITUTION:The magnetic head has the slider 3 equipped with a magnetic core, the gimbal 5 mounting the slider 3 almost on its center, a base board 6 for fixing and holding the periphery of the gimbal 5, and FPC 14. The fixing position between the FPC 14 and the gimbal 5 is set up vertically to the rotating direction of the medium and allowed to almost coincide with the center position of the gimbal 5. Since the center of the slider 3 is allowed to almost coincide with the fitting position of the FPC, moment based upon force applied in the W direction is almost zero. Consequently, stable magnetic recording or reproducing can be attained without inclining the slider 3.
