Title: Drawing die for metal
Inventor: OGASAWARA MASANOBU
IPC: B21D22/26
Filed: 1978-04-28
Abstract: PURPOSE: The simply constructed die which can complete the deep drawing through one pass, by forming the projection thread at the conical part of the truncated conical punch.  
     CONSTITUTION: At the conical part 10 of the drawing punch whose head is formed into a truncated cone, plural projecting threads with approximately triangular section are formed on the planes vertical to the axis of the punch. These projecting threads can be formed into the ring type 11, the segments 12 separated into plural pieces, or the ring type thin tongued and grooved face 13. This punch is pushed down to thrust the blank 16 being held by the die 14 and the blank-holder pad 15; hereby, the drawing is given to the blank 16 starting at the corner part at the tip of  punch. By further pushing down the punch, the blank 16 contacts with the projecting thread 11'  of the punch  and then is penetrated; after that, the blank 16 is pressed by the penetrated part, so  that the enlongation between the projecting threads 11' is reduced from the corner part at the tip  of the punch, being locally elongated until then. Similary, the blank 16 is penetrated by the projecting thread 11 and the elongation of the blank 16 between both projecting threads 11, 11', is  reduced. Hereby, the elongation is dispersed and the breaking of the blank 16 at the corner part  of the drawn bottom plane is prevented.

Title: Recording and reproducing device
Inventor: SEKIMOTO TETSUSHI
IPC: H04N7/08
Filed: 1979-04-26
Abstract: PURPOSE: To prevent the occurrence of cross talk as much as possible without limiting the recording-dedicated band of video signals, by bringing the time-division recording of audio signals and video signals to effect.  
     CONSTITUTION: In each horizontal blanking interval H-BLK (about 11μS) of video signals, the time-dividing multiple recording of FM autio signals AL and AR of two channels comes into effect. Here, audio signals AL and AR are intermittently recorded in horizontal blanking H-BLK being time-compressed and restored into a continous signal in reproduction. Since luminance signals and recording FM audio signals are time-divided mutually, cross talk can be avoided even by overlapping bands of FM audio signals AL and AR with the lower side-band (higher side of luminance signal) of FM luminance signal Y-FM. The deviation frequency of FM luminance signal Y-FM can therefore be lowered and the recording-dedicated band can be used more effectively.

Title: Helicopter
IPC: B64C27/06
Filed: 1992-03-10
Abstract: PURPOSE:To generate moment acting in a direction in which torque generated through rotation of a main rotor is cancelled and to improve an advancing speed by forming the fuselage of a helicopter laterally asymmetrically about a central line. CONSTITUTION:Provided that the rotational direction of a main rotor is counterclockwise as seen from above, a helicopter is formed in a laterally asymmetrical shape about the central line 13 of the helicopter, the outline of the left board side of a fuselage 31 is formed in a linear shape, and a horizontal tail 36, a vertical tail 7, a tail rotor 32 are mounted on a rear end part. As a result, aerodynamic resistance on the left board side is increased, yawing moment 34 is generated around a center of gravity 9 owing to an asymmetrical shape and exerted in a direction in which torque 11 generated by rotation of the main rotor is cancelled. Thereby, a tail rotor loss can be reduced. Further, as a result of limiting the arrangement of the horizontal tail 36 only to the one side of the vertical fail, aerodynamical resistance ranging from the central line 13 of the fuselage to the left board side is increased, yawing moment around the center of gravity 9 is increased, and a tail rotor loss is reduced.
