Title: Moving blade of turbine
Inventor: KAWASAKI SAKAE
IPC: F01D5/14
Filed: 1981-04-15
Abstract: PURPOSE:To reduce the secondary flow loss at the root of a moving blade by a method wherein the deflection angle at the position within a specified range of distance from the root of the moving blade is rendered to be smaller than the deflection angle at the root of the moving blade by an angular range of specified value on the impulse stage moving blade of an axial flow turbine. CONSTITUTION:The position, which lies in the distance H from the root of the moving blade of the turbine and the distance H satisfies with the following relation, 1.05<=(Di+2H)/Di<=1.15 (wherein Di is the root diameter of the moving blade of the turbine) is determined. The deflection angle at the position with the distance H is rendered to be smaller than the deflection angle at the root by the value in the range of 0-7 deg.. Now that the deflection angle epsilonb at the position with the distance H is rendered to be smaller thanthe conventional deflection angle, which is equal to he deflection angle epsilona at the root, flow lines 62 can have larger radii of curvature than conventional flow lines 61, resulting in enabling to reduce the pressure difference angle the passage from the front surface 31 side to the rear surface 32 side. In such a manner as mentioned above, the development of the secondary flow within the moving blade is suppressed.

IPC: G01N27/62
Filed: 1992-03-16
Abstract: PURPOSE:To improve the identification reliability of an unknown sample by performing retrieval by using two drift voltage-mass spectrum sets by switching the drift voltages. CONSTITUTION:When a drift voltage is set from a data processing section 3 as a measuring condition, a drift power source control circuit 7 starts to work through a control system 2 and the mass spectrum which is obtained when a desired drift voltage is applied is obtained.

At the time of performing mass spectroscopy on an unknown sample, the two drift voltage-mass spectrum sets are similarly obtained and the sample is identified based on the resemblance by successively retrieving the library on the disk 6 for the obtained two drift voltage-mass spectrum sets.

Title: Plastics selection method and device therefor
IPC: B29K105/26
Filed: 1992-03-16
Abstract: PURPOSE:To select plastics out of waste materials, such as paper and wood chips. CONSTITUTION:While waste materials are dropped, in the drop path, a wind is horizontally fed by an air blower from crosswise to blow off paper or plastics of a small specific gravity into a horizontal path 3 disposed in the crosswise direction. By the wind force of the air blower, the waste materials of a small specific gravity horizontally come into collision with an upward travel part 4a of a hot plate 4. Paper and wood chips 15 in the colliding waste materials drop downward at once without attaching to the hot plate. With respect to plastics 16 colliding with the hot plate 4, the colliding part is melted by the heat of the hot plate to be fused to the hot plate 4. Thus, the plastics moves upward together with the hot plate 4. After moving upward, the plastics 16 successively moves downward. At this time, the plastics 16 is scraped off the hot plate 4 by an edge of a cutting knife 7 provided on the travel path.

Title: Video signal reproducing device
Inventor: SATO TAKAHARU
IPC: H04N5/783
Filed: 1986-03-18
Abstract: PURPOSE:To freely select a speed in slow motion reproduction by properly limiting the number of timing pulses which are generated, and thus varying the frequencies of the start and stop of a recording medium and varying a reproducing speed. CONSTITUTION:A trigger signal is inputted to a multivibrator 9 and then a capstan motor 12 begins to drive a tape to be reproduced normally after a certain time determined by the time constant of the multivibrator 9. Then, when the time required to run the tape by a quantity corresponding to one frame is elapsed, the motor 12 is reversed and braked by an FF 14 to stop and still picture reproduction is carried on thereafter unless the trigger signal is inputted to the multivibrator 9. Thus, the degree of the slow speed of intermittent feed type slow motion reproduction varies according to the ratio of normal reproduction and still reproduction, so a signal outputted once for one frame of an edge detecting circuit 7 is limited by an AND circuit 8 to vary the degree of the slow speed.
