Title: Light-emitting element
Inventor: EDA KAZUO
IPC: H05B33/12
Filed: 1981-01-20
Abstract: PURPOSE: A novel light-emitting element that is composed of a semiconductive polycrystal sinter in which injected electrons emit light on the recombination centers, when a voltage is applied to the surfaces of crystal grains with schottky type energy barrier, thus being used as a display having ZnO varistor characteristics.  
     CONSTITUTION: For example, a ZnO powder is calcined in an alumina crucible at 1,350°C in air to give a sintered powder. Then, it is mixed with H 3 BO 3 , BaO, ZnO and Co 2 O 3  and they are calcined in an alumina crucible in air at 1,200°C for 30min. Then, they are rapidly cooled to give a glass powder. The resultant ZnO powder, a glass powder and a silver oxide powder are mixed, then an organic binder is added by 20wt% to form a paste. An alumina base plate 11 coated by printing with silver paste 12 to form electrodes is further coated with the above paste of polycrystal sinter 13 by printing, and sintered in air at 900°C for 5min to give the objective light-emitting element.  
     USE: High-resolution display element and large-screen display element.

Title: Method of winding tubular film
Inventor: KANAI SHINICHI
IPC: B65H41/00
Filed: 1984-01-18
Abstract: PURPOSE:To avoid leaving a curl by cutting open a tubular film without cutting off the end of the film and laterally reciprocating the film within a small range to be wound into a roll. CONSTITUTION:A tubular film 1 having the inner surfaces closely adhering to each other is cut open by a cutter 16 of a cutting device 3 without cutting off the edge thereof to be respectively wound as one sheet film round a take-up shaft 9 through a guide roll 4, guide rolls 5, 6, 7 and a touch roll 8. Frames 10, 11 are oscillated right and left by a driving source 14, so that the film 3 is laterally reciprocated and rolled round the shaft. Thus, a difference in diameter of the film roll between the ends and the central portion thereof can be avoided to roll the film round the shaft in a good winding manner.

Patent JP-S62167948-A (JP)
Title: Shock absorber
Inventor: ISHIYAMA SHIGETOSHI
IPC: F16F9/48
Filed: 1986-01-20
Abstract: PURPOSE:To delicately absorb the shock at the time of collision, by adjusting the 'contracting speed' of a shock absorber in such a manner that the speed becomes slow as the stroke advances. CONSTITUTION:When a body 10 collides with the tip of a rod 3 of a piston 2 at a high speed, the speed V of the piston 2 in a contracting stroke is equal to the speed which is determined by both viscosity of the oil and the intensity of a spring 5. As the stroke advances, however, the area of a port 7 gradually becomes smaller. As a result, the flow rate of the outgoing oil decreases, and the 'contracting speed' V gradually becomes slower. Thus, finally, the speed becomes zero, as is shown by a speed-stroke curve when the curve touches the stroke coordinate axis. In other word, the piston is stopped smoothly when the total stroke is completed.

Abstract: PURPOSE:To improve the durability of a pulley and a belt by fixing a primary control valve so that the primary pressure becomes maximum at the time of failure such as disconnection or the like, and preventing the abnormal pressure rise with a relief valve device provided in a circuit between a primary cylinder and the primary control valve. CONSTITUTION:A non-stage transmission 5 is controlled for speed change on the basis of the primary pressure of a primary control valve 60 to be controlled by a primary control unit 72. In the case that the electrical signal is not input because of disconnection or the like, the primary pressure is made maximum to forcedly fix the non-stage transmission 5 to a high-speed stage of the minimum speed change ratio for fail-safe so that the quick deceleration and a slip of a belt 26 is not generated. At this stage, when the primary pressure rises more than a required value with the secondary pressure, the oil pressure of a primary cylinder 21 is restricted by a relief valve device 81 to avoid an overload of the belt 26 and pulleys 22, 25. Durability of the belt is thereby improved to eliminate unrequired increase of rigidity.
