Granted: 1990-09-21
Abstract: A number of final stages of the output buffer circuits are connected to respcetive output terminals. A number of driving buffer circuits have a current handling capacity smaller than current handling capacity of the output buffer circuits, operatively connectable to said final stages. These drive the final stages, the switching speed of the driving buffer circuits being controlled to be in the range of three to five times the switching speed of the output buffer circuits. This blunts the input vaveform of the output buffer circuits and reduces noise in the circuit caused by current variation in the output buffer circuits. A wiring device operatively connected between the final stages and the driving buffer circuits, connects selected ones of the driving buffer circuits.

Abstract: The polyurethane resin binder comprises (a) a polyester  diol of 500- 5000 molecular wt., having a linear terminal  hydroxyl  gp. and containing -SO3X [X= alkali metal  gp. in the molecular chain, (b) a triol of formula (I) having  a  tertiary  amino  gp.  and  a secondary hydroxyl gp., and (c) an organic diisocyanate. In (I), R and R' are each -(CH2)n-(OCH2CH2)m [m = n = 0-6 ; R"  is  -(CH2)l-C(CH3)H- [l = 0-3 . The binder  has  an  improved  durability  and abrasion-  resistance  in  the  magnetic  layer  of  the  magnetic recording medium.

Abstract: 모우터를 동력원으로하여 빠찡꼬 구슬의 송출을 실시하는 제어장치에 있어서, 송출의 조건에 따라서, 모우터의 구동전류등을 제어하여, 빠찡꼬 구슬의 확실한 송출을 실현한다. 
     경품구슬을 불출하는 송출장치의 빠찡꼬 구슬 배출쪽에 경품구슬 확인 스위치를 형성하고, 경품 구슬의 확인이 되면, 송출장치의 구동속도를 증대하고(스텝S170), 구슬막힘이나 빠찡꼬 구슬의 공급이 늦어져서 소정시간내에 빠찡꼬 구슬의 배출을 할 수 없는 경우에는, 구동 속도를 저하하여 구동 토오크의 증대를 도모한다(스텝 S190). 최저속도로 하더라도 여전히 경품 구슬의 확인을 할 수 없는 경우에는, 송출 장치의 스텝핑 모우터를 역 회전하여(스텝 S220), 빠찡꼬 구슬의 물림을 해소한다.
