Title: Production of high-density columnar particle oriented ceramic
Inventor: MIYAHARA KAORU
IPC: C04B35/622
Filed: 1995-06-27
Abstract: PURPOSE: To obtain a ceramic material having high strength with small variation in the strength and having excellent toughness by applying a sintering assistant on columnar ceramic particles, then applying a ceramic source material on the particles, compacting and calcining in a specified shape. CONSTITUTION: A sintering assistant 2 is applied on the surface of columnar ceramic particle 1 as the core, on which a ceramic source material 3 of the same material as the columnar ceramic particle is applied. These particles are compacted while oriented along a specified direction. The obtd. compacted body is fired so as to grow the columnar particles as the cores to obtain the objective high-density columnar particle oriented ceramic material. To coat the columnar source material particle, a short fiber such as a whisker (columnar source particle) comprising the main component of the objective ceramic material is used as the core. After the sintering assistant is applied on the surface of the whisker, the ceramic source material same as the core ceramic material is applied on the surface of the particle.  The material used is, for example, selected from nonoxide ceramics such as silicon nitride and silicon carbide or oxide ceramics such as alumina and mullite.

Title: Rainwater infiltration preventive device of combustion apparatus
Inventor: SUGIMOTO WATARU
IPC: F24H9/02
Filed: 1985-07-19
Abstract: PURPOSE:To weaken the force of rainwater infiltrating obliquely into the main body of the apparatus and to cause the rainwater to fall between horizontal plates and a perpendicular plate to prevent ingress of rainwater into a combustion part by providing a plurality of horizontal plates in parallel to an exhaust gas flow in the vicinity of an exhaust gas outlet part within an exhaust cylinder of the combustion apparatus and also providing a perpendicular plate from the lower surface of the exhaust cylinder at the remote position from the horizontal plates. CONSTITUTION:When wind blows, rainwater infiltrates into the inner part of a horizontal cylindrical portion 1a through an outlet portion 10 of an apparatus main body 4 and an exhaust cylinder 1. Rainwater certainly hits against any of the plurality of horizontal plates 2, and repeats reflection between the upper surface of the horizontal plate and the lower surface of a horizontal plate at the upper part of said horizontal plate, thus gradually decreasing the force of rainwater. Rainwater falls onto the lower part of the exhaust cylinder 1 between the perpendicalar plate 3 and the horizontal plate 2, and is stored at the lower part of the exhaust cylinder 1. Stored rainwater is discharged to the outer part of the apparatus main body 4 without falling onto an exhaust fan 5 and a burner 7, which are located at the remote part of the perpendicular plate 3.

This coloring matter has high stability even at a comparatively high temperature and high humidity and has no oxidation nor deterioration in the air. In addition, the heat conductivity of the coloring matter is set at <=1/10 compared with that of a metal. Thus the optical recording is possible with high efficiency by irradiating the laser light 30 of loe energy from the recording layer side or the laser light 50 from the substrate side.

Title: Information recording/reproducing apparatus and latch mechanism used therefor
Inventor: KITAGAWA KATSUKI
IPC: G11B21/22
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording and reproducing apparatus whose sensivity with respect to a rotation shock and an angular acceleration around a pivot shaft is increased by, when an inertial member is moved, it is directed on the circumference which has the pivot shaft of a rotary actuator as the center and a latch member latches the rotary actuator. SOLUTION: As soon as the whole of an HDD receives a rotation shock in the clockwise direction, an inertial member 106 pushes the arm 109 of a latch member 104, and the latch member 104 receives its force so as to be moved to a lock position. Since one end of a rotary actuator is restrained by a claw 108, it is possible to prevent the rotary actuator from being turned in the counterclockwise direction. Since the rotation center of the inertial member 106 agrees with the pivot shaft of the rotary actuator, an information recording and reproducing apparatus can respond, with good sensitivity, to the rotation shock and the angular acceleration around the pivot shaft of the rotary actuator.
