    摘要： Respective current supply means (I.sub.A, I.sub.B) control conducting periods of corresponding transistors (Q.sub.3, Q.sub.4), whereby conducting periods of driving transistore (Q.sub.6, Q.sub.7) are also controlled. Thus, periods in which both of the driving transistors (Q.sub.6, Q.sub.7) simultaneously enter ON states are reduced and through current (I.sub.S) flowing to the ground level GND through the driving transistors (Q.sub.6, Q.sub.7) is reduced. A pull-down transistor (Q.sub.8) controls a conducting period of the driving transistor (Q.sub.7), whereby periods in which both of the driving transistors (Q.sub.6, Q.sub.7) simultaneously enter ON states are reduced and the through current (I.sub.S) is reduced.

    摘要翻译： 相应的电流供应装置（IA，IB）控制对应晶体管（Q3，Q4）的导通周期，从而也控制驱动转换周期（Q6，Q7）。 因此，同时进入导通状态的驱动晶体管（Q6，Q7）同时进入的周期减少，并且通过驱动晶体管（Q6，Q7）流到地电平GND的通过电流（IS）减小。 下拉晶体管（Q8）控制驱动晶体管（Q7）的导通周期，由此同时进入导通状态的两个驱动晶体管（Q6，Q7）的周期减少，并且通过电流（IS）减小。

    摘要： A method of producing a polyurethane molded article is provided, in which one molding machine which can provide distinctly polyisocyanate component(s) and two kinds of polyol components is used, and prior to completion of the feed of a first polyurethane mixture liquid containing a polyisocyanate and a polyol component without a blowing agent into a mold, a second polyurethane mixture liquid containing a polyisocyanate and a second polyol component with a blowing agent is fed into the mold. The method produces, in a single stage, a polyurethane foam molded article having the skin or high density portion selectively formed on portions of the molded article actually requiring them, where the proportions of the skin and the high density portion and the foamed core can be varied freely.

    摘要： Transmitting and recording methods, a reproducing method, and a reproducing apparatus of compressed video and audio signals which can easily realize a retrieval on a picture group unit basis. Packs are formed from a stream of compressed video and audio data and independent data. The pack is divided into a minimum unit of a data structure peculiar to a medium. When transmitting through or recording on the medium, information indicating whether or not a boundary of a picture group exists in the minimum unit is described in a sub information portion in a frame signal and is transmitted or recorded. Upon reproduction, by using the information which had been added to the sub information portion and was transmitted or recorded, the video data can be retrieved at a high speed every predetermined unit.

    摘要： A disk cartridge system including different types of disk cartridges for use in a cartridge drive apparatus, including first and second disk cartridges. The first disk cartridge including a first case having a substantially rectangular shape with first, second, third and fourth edges, the first edge of the case being delimited by a first corner portion connecting the first edge and second edge and a second corner portion connecting the first edge and the third edge. The first case has a first groove at a side plane of both of the second and third edges. The first case also has a first cutout portion at both of the second and the third edges and extending in a direction of and passing through the thickness of the first case. The second disk cartridge includes a second case with a substantially rectangular shape with fifth, sixth, seventh and eighth edges, the fifth edge of the second case being delimited by a fifth corner portion connecting the fifth edge and sixth edge and a sixth corner portion connecting the fifth edge and the seventh edge. The second case has a second groove at a side plane of only one of the sixth and seventh edge. The second case also has a second cutout portion at both of the sixth and the seventh edges extending in a direction of the thickness of the second case without passing through the thickness of the second case. A length, width and thickness of the first case are substantially equal to a length, width and thickness of the second case.

    摘要： A method of providing a fibrous thermoplastic resin for depolymerization thereof wherein the fibrous thermoplastic resin is formed into a shaped article having a specific gravity of at least 1/2 of the true specific gravity of the fibrous thermoplastic resin, said shaped article consisting of the fibrous thermoplastic resin mass having on its surface a crusty thin resin layer which may be press-bonded or melt-bonded to the mass. The thus provided shaped article of the fibrous thermoplastic resin can be advantageously employed as a starting material for the depolymerization reaction. In accordance with this invention, the time required for completion of the depolymerization can be greatly shortened as compared with that of the conventional technique and the rate and efficiency of the depolymerization can be greatly improved. Further, according to this invention, fibrous thermoplastic resins can be depolymerized effectively on an industrial scale while automatically conducting unit-operations such as storing, transportation, weighing, and charging into a reaction vessel in much simplified manners.
