Title: Compacting pressing device for granular body
Inventor: IWASADA KAZUMI
IPC: B30B11/04
Filed: 1980-12-11
Abstract: PURPOSE: To perform uniform compacting pressing by small pressing force, by permitting a container side plate parallel to a compacting pressing direction to move in prallel to the compacting pressing direction in a container wherein a granular body is compressed closely.  
     CONSTITUTION: The side plate 3 of a compacting pressing container 4 is permitted to move up and down, and a guide roller 7 is provided outside it. A prescribed amount of a granular body 5 is thrown in the compacting pressing container 4, a supporting base 8 is detached as shown by arrows, and pressure is  applied by a pressing device 6 from above. When the granular body 5 is compressed closely to lower the upper part of the granular body 5 by compacting  pressing, compacting pressing force is transferred as shown by an arrow (x) to  a movable side plate 3 by frictional force, pressing down the movable side plate  3. At this time, since a bottom plate 2 is fixed, the downward movement of the  movable side plate 3 is recovered as compacting pressing force in an (y)-arrow  direction at the lower part. Consequently, almost all pressing force by the pressure device 6 is used for the compacting pressing, thereby performing uniform  compacting pressing effectively.

Title: Brushless motor
Inventor: ENDOU MINETSUGU
IPC: H02K29/00
Filed: 1981-11-02
Abstract: PURPOSE:To obtain the smooth rotation of a rotor by displacing the mechanical central position of pole pairs from the electric central position of a stator pole, thereby substantially non-existing the position where the toque becomes zero. CONSTITUTION:When a coil A is energized, torque becomes zero at 180 deg. and 360 deg. in the drawing, but the mechanical central position C2 which attracts the magnetized part of the rotor 1 with the pole pairs of a stator 2 is displaced from the electric central position C1 of the pole pair of the stator 2 when the coil A is energized at theta. Accordingly, the generated torque becomes the synthesis of the torque obtained by energizing the coil A and the torque obtained by attracting between the rotors of the stator pole pair. In this manner, since no position where the turque becomes zero exists, smooth rotation can be continued.

Title: Picture memory device
Inventor: HORII HIROYUKI
IPC: H04N9/82
Filed: 1986-07-25
Abstract: PURPOSE:To prevent distortion of a signal and degradation of characteristics by providing presettable counters for a memory element for luminance signal and that for color difference signal independently of each other. CONSTITUTION:The preset value of a Y memory 6 is set to a counter 9 of a memory 3, and the preset value of R-Y and B-Y memories 7 and 8 is set to a counter 10. Preset values are set to counters 9 and 10 independently of each other. In an NTSC decoder 1 and an NTSC encoder 4, a difference occurs between a luminance signal Y and color difference signals R-Y and B-Y with respect to delay time. Preset values of counters 9 and 10 are shifted by the counted value corresponding to this difference of delay time. Thus, the difference of delay time of each signal is absorbed and distortion of the signal and degradation of characteristics are prevented when the luminance signal and color difference signals are separated or synthesized in the NTSC system.
