Title: Method for detecting tracking error of disc-like information recording medium
Inventor: YOSHITAKE YUUJI
IPC: G11B21/10
Filed: 1983-06-24
Abstract: PURPOSE:To detect precisely a tracking error without missing a tracking error by reproducing a disc-like information recording medium at a fixed reproducing speed and comparing the values of address signals obtained before and after the prescribed rotational frequency of the recording medium. CONSTITUTION:A reproducing device 10 reproduces the disc-like information recording medium (disc) on which plural address signals indicating the position of a recording program are recorded every rotation at a fixed reproducing speed. A detecting device body 11 receiving the reproduced signals compares the values of address signals obtained before and after the prescribed number of revolutions of the disc respectively. When the difference between both the values is dissident with a value corresponding to the reproducing speed and the prescribed rotational frequency, the existence of a tracking error is decided. Thus, the tracking error can be precisely detected without missing the error.

Filed: 1980-08-19
Abstract: PURPOSE: To improve performance of a gear pump largely by a method wherein side clearance of the gear pump is reduced to zero by giving back pressure corre sponding to the internal pressure of the pump to the side face to the gear, preparing plural number of conducting passage from one of the contacting surface of the gear and from the side face to the back side of the other.  
     CONSTITUTION: When gears 31 and 32 are rotated to the direction of arrows I and II respectively, fluid sucked from the suction port 44 will gain a certain pressure and is sent to the discharge port 45. And the pressuring fluid being forced to move at each point in the pump from suction port 44 to discharge port 45 is led to the back face of the side plates 33, 34, 35, 36 respectively through lead hole 38 and being separated by the pressure hole 39 prepared to the elastic body 40 forming back pressure corresponding to each part of the pump. The back pressure balanced with initial pressure of the pump is obtained without any special working to the side plates, and the side clearance can easily be reduced to zero at low cost, enabling to improve pump performance largely.

Title: Magnetic head supporting body
Inventor: MATSUMOTO MASAAKI
IPC: G11B21/21
Filed: 1987-05-13
Abstract: PURPOSE:To minimize a spring constant even under the state of the same curvature form and to obtain a required pressing load by forming a spring part generating the pressing load for a magnetic head supporting body with super elastic materials. CONSTITUTION:A slider 1 is connected via a gimbal 6 to a beam part 2 of a load arm while the beam part is connected by a connector part 4 via the spring part 3 to a guide arm 5. This spring part 3 is made of such super elastic materials as a Cu-Sn-Al alloy, etc., and connected with other parts so that the pressing load is generated by this deformation in the vertical direction against the slider 1. Because of using the super elastic materials, the initial form of the spring part 3 is rather a bent shape. This initial form is deformed until it is approximately paralleled with a disk surface, thus specifying its materials in the range of super elasticity. Because only the spring part is thus made of the super elastic materials and by the gimbal 6 and the beam part 2, an in-plane rigidity is ensured and in addition the spring constant can be minimized.

Title: Surface pumping laser
Inventor: MORI AKIYOSHI
IPC: H01S3/0915
Filed: 1984-06-05
Abstract: PURPOSE:To prevent damage of optical components and the structure by reducing the power density of axis off-set laser beams by a method wherein the region in the end surface of an active medium which generates laser beams which are prevented from emtting again in parallel with the axial line after passing through the active medium is formed into a diffusion surface. CONSTITUTION:In the conventional surface pumping laser, of laser beams incident from the end surface 5 of the laser active medium, a beam lower than H in length from an optical smoothed surface 4 does not emit from other end surface in parallel with the axial line 2 after passing through the laser active medium 1. The region D on the end surface 5 which causes such a beam is kept in a diffusion surface. A laser beam 10 incident to this regiond D is diffused in every direction into axis-off beams, and the damage of optical components or the structure can be prevented because of the decrease in power density of the laser beam. It is the same with laser beams incident from the other side surface 6, and the region E on the end surface 6 corresponding to the height H from an optical smoothed surface 3 is formed into a diffusion surface.

Abstract: PURPOSE: Combination of a low-density moving layer that is provided in the fluidized bed of the cracking column, a pipe for transporting fluid flow and means for detecting pressure drops blows up the fluidized particles into the upper part of cracker in stabilized and controlled state to prevent coking thereon.  
     CONSTITUTION: Particles which are introduced into pipe 22 equipped for transporting fluid flow in cracving column 1 are blown up to the inlet of pipe 8 by fluid- flow-transporting gas 13 and run into pipe 8. As particles flying up from the top surface of fluidized bed 4 collide against insert 26 and fall back, almost particles directly flying into pipe 8 come from pipe 22. Particles in pipe 8 collide against walls of pipe during passing through the pipe to pare off coke depositing on the wall to reduce pressure drop due to the decrease in the sectional area of the pipe. The reduction in pressure drop is detected by differential pressure detector 33 to operate controller 34 and control valve 35 , thereby decreasing the amount of particles introduced into pipe 22
