    • A refrigeration system includes a variable-capacity compressor having a compression chamber for sucking and compressing a refrigerant and a crankcase surrounding a swash plate forming a drive portion for suction and compression, and a passage through which the refrigerant discharged from the outlet of the compression chamber passes at least through a condenser, an expansion means and an evaporator and is sucked into the inlet of the compression chamber of the compressor, the capacity of the compressor being changed by slanting the swash plate during its rotation. A pressure control device is provided in a refrigerant passage between the evaporator and the suction valve of the compressor whereby the pressure upstream thereof is controlled in such a manner that it does not decrease below a predetermined value, thereby preventing frosting of evaporator fins. A point partway along the passage upstream from the pressure control device and the crankcase of the variable-capacity compressor are communicated so that the capacity of the compressor may be controlled without controlling the pressure in the crankcase.
    • 制冷系统包括具有用于吸入和压缩制冷剂的压缩室的可变容量压缩机和围绕形成用于抽吸和压缩的驱动部分的旋转斜盘的曲轴箱,以及从压缩室的出口排出的制冷剂的通道 至少通过冷凝器,膨胀装置和蒸发器,并被吸入到压缩机的压缩室的入口中,通过在旋转期间倾斜斜板来改变压缩机的容量。 压缩控制装置设置在蒸发器和压缩机的吸入阀之间的制冷剂通道中,由此上游的压力被控制为使其不降低到低于预定值,从而防止蒸发器翅片的结霜。 通过压力控制装置上游的通路和可变容量的压缩机的曲轴箱的连通点,能够控制压缩机的容量而不控制曲轴箱内的压力。

    • In a semiconductor memory which is provided with a memory cell array, word lines and bit lines for selecting a desired one of memory cells of the memory cell array and a detector circuit for detecting a read current of the selected memory cell, the detector circuit is composed of a pair of transistors having their bases cross-connected so that a hysteresis characteristic is provided by flowing a current in the transistors, and the current is controlled by a hysteresis control circuit to flow only when all word line potentials monitored by the hysteresis control circuit have become lower than a predetermined value, whereby to remove the influence of a noise in the detection of read information of the selected memory cell.
    • 在设置有存储单元阵列的半导体存储器,用于选择存储单元阵列的所需一个存储单元的字线和位线以及检测所选存储单元的读取电流的检测器电路中,检测器电路是 由一对晶体管组成,它们的基极交叉连接,使得通过使晶体管中的电流流过来提供滞后特性,并且仅当滞后控制所监视的所有字线电位都由滞环控制电路控制电流 电路已经变得低于预定值,从而在检测所选择的存储单元的读取信息时消除噪声的影响。
