IPC: H04N13/04
Filed: 1987-04-07
Abstract: PURPOSE:To directly view a cubic picture without putting on a lens or glasses by using liquid crystal in an element displaying respectively different image signals for cubic pictures and overlapping a contrast change with respect to the optic angle and the picture of a half mirror. CONSTITUTION:The contrast of a liquid crystal panel changes in accordance with an angle which a man views with eyes. Contrast becomes maximum at an angle theta1, and small at an angle theta2. In the position of a man's eye A, the contrast of the displayed picture in a liquid crystal panel 3b is viewed large, and the contrast of the displayed picture in a liquid crystal panel 3b small. In the position of a man's other eye B, the contrast of the displayed picture of the liquid crystal panel 3a is viewed small, and the contrast of the displayed picture in the liquid crystal panel 3b large. Consequently, the displayed picture in the liquid crystal panel 3a can mainly be viewed in the position of a man's eye A, and the displayed picture in the liquid crystal panel 3b in the position of a man's eye B, whereby the displayed picture can be viewed three- dimensionally.

Title: Production of ultrasonic locator
Inventor: KAMIYAMA YASUSHI
IPC: G01N29/24
Filed: 1978-07-12
Abstract: PURPOSE: To enhance the resolution of a locator and to improve the directive characteristics by cutting a piezoelectric element to such an extent that flaws are formed in the packing member and by forming flaws in the flat electrode of the other side of the packing element at a pitch several times the element cutting pitch.  
     CONSTITUTION: Electrodes 4 and 4' are mounted from the upper side of a packing element 3 for absorbing ultrasonic waves to another side which is positioned at a right angle or another angle with respect to the former. A piezoelectric element 1 adhered to the electrode 4. A number of cut grooves 5 are formed in the upper side of the element 1 by means of a cutter to such an extent that they slightly eat the packing element 3 so that the element 1, the electrode 2 and the electrode 4 are divided into n pieces. Since, however, the other electrode 4' is not divided, the electrode 4' at this side is cut with grooves 6 every several oscillators so that plural oscillators are connected to form one block. By accomplishing the cutting operations twice in different directions, it is possible to enhance the resolution of the locator and to improve the directive characteristics of the ultrasonic waves.

Title: Antiisinking member for wheel to move on snow or sand* and method of attaching said member
Inventor: POORU RAKURUWA
IPC: A43B3/12
Filed: 1978-07-13
Abstract: In a sliding needle bar tufting machine in which displacement of a needle bar transversely of a tufted fabric undergoing manufacture to create a pattern in the fabric is effected by the action of rotary cam means on a needle bar carrier member, the invention provides single or single-acting cam follower means on the needle bar carrier member and a pair or appropriately spaced rotary cams of conjugate shape acting on said cam follower means. The use of two cams of conjugate shape makes it unnecessary for the individual cams to be symmetrical about their centers of rotation and thereby enables the production in the fabric of patterns which are asymmetrical in character.

Title: Linear speed control method
Inventor: KURATA HIROSHI
IPC: G05D13/62
Filed: 1993-04-13
Abstract: PURPOSE:To speedily attenuate the swing of a dancer, etc., by detecting the rate of variation in the length of a long-sized member with time and adding the rate of time variation as a control element of feedback control. CONSTITUTION:The long-sized member 10 after being wound around a dancer device 40 (n) times is taken up around a take-up drum 30. The length (l) of the long-sized member 10 is detected as the displacement (y) of the free pulley (dancer) 41 of the dancer device 40 wound with the long-sized material 10. Further, the displacement speed (v) (i.e., up-down speed of dancer 41) of the dancer 41 is detected as the time variation rate (v=dl/dt) of the length (l) of the long-sized member 10. This speed (v) can be found by performing arithmetic (DELTAy/DELTAt) based upon variation DELTAy in the displacement (y) of the dancer 41 in a time DELTAt. A motor torque adjuster 60 feels this displacement (y) back to perform proportional control and uses the product of the speed (v) and a gain as a control element to adjust the torque (r) of a motor 50 so that the dancer 41 reached a target position.

SOLUTION: A head holder 25 holds a thermal head 21 and is rotatable centered around a shaft 25B. A head pressure contact pin 23 presses the thermal head 21 by the spring force of a compression coil spring 24, and causes an ink sheet 12 to come into contact tightly with a recording paper 15 to be brought into contact with a platen roller 17 under pressure. A pressure contact cancellation means is constituted in such a manner that is causes a rotary cam 26 to slide on a pressure contact cancelling lever 27 and the rotary can 26 is rotated to fluctuate the pressure contact cancelling lever 27 centered around a rotating shaft. In turn, a protruding part 25A provided on a head arm 25 is pushed up to separate the thermal head 21 from the platen roller 17.  Consequently, it is possible to constantly obtain a stable pressure contact force when a recording head is brought into contact with a platen under pressure and also ensure the positive separation of the recording head from the platen during separating operation.
