IPC: G01N3/32
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To discriminate a fine crack in a short time by applying a mechanical stress to the outer surface of ceramics. SOLUTION: A plurality of honeycomb structures 1 using cordierite porous material having a diameter of 101.6mm and a length of 127.0mm are introduced into an electric furnace held at 900 deg.C, held for 60min, then removed, and all are conducted by visual and hammering checks. Then, the sample in which the crack is not recognized by the visual check is checked by a 20-times stereomicroscope, and the samples in which the crack is confirmed by the visual and stereomicroscope checks and not confirmed are divided by halves.  The end faces of them of the half number are polished at about 1.0mm of sample feeding amount and the specific number of resolutions by an abrasive adhered with diamond grains, and the end faces of the other half number are sandblasted by using nylon or polyplastic for 5 to 10sec in response to the wall thickness separately at 100mm from the end by specific pressure by an air gun having a specific diameter. As a result, the part of fine crack 3 which is impossible to be visually confirmed with polishing and sandblasting is cutout in a V-shape from the end face 2 of the structure 1, and can be sufficiently visually confirmed.

Title: Turntable
Inventor: HARA YOSHITAKA
IPC: G11B19/20
Filed: 1983-04-14
Abstract: PURPOSE:To improve the rigidity of a turntable through its geometric effect without changing the weight and material by constituting the turntable so that it inclines toward the recording disk placing surface side from the central part to the outer periphery. CONSTITUTION:A turntable 21 is formed in such a way that it inclines, for example, linearly toward the recording disk placing surface 213 side from the central part 211 to the outer periphery 212. Therefore, the outer periphery 212 becomes higher in elevation than the central part 211. Moreover, in this case, the inclination of the tapered surface 214 at the recording disk placing surface side 213 is set so that it becomes smaller than the inclination of the tapered surface 216 of the opposite side 215. As a result, the thickness t2 of the outer periphery 212 of the turntable 21 is thinner than that t1 of the inner peripheral part 211. The turntable 21 is equipped with ribs 217 and 218 at the central part 211 and outer periphery 212 to support the non-signal part of a recording disk. Therefore, the moment of inertia is overlapped and rising time of the turntable can be made faster.

IPC: G03H1/02
Filed: 1989-03-20
Abstract: PURPOSE:To increase sensitivity and response speed by forming a carrier trap on the conjugated principal chain of long-chain conjugated molecules or a polymer having a structure lacking reversal symmetry. CONSTITUTION:A carrier trap such as an electron or positive hole trap is formed on the conjugated principal chain of long-chain conjugated molecules or a polymer having a structure lacking reversal symmetry. The carrier trap can be generally formed by controlling the arrangement of donor groups (D) and acceptor groups (A) in the molecules or polymer. For example, the groups D, A added in the order of D, A, D, A,... are rearranged in other order in the middle of the sequence. Since a carrier trapping function is rendered to the conjugated polymer having a significant Pockels effect, a photorefractive material having superior sensitivity and a high response speed is obtd.
