    • An automatic air conditioning system for automotive vehicles including discharge outlets for discharging conditioned air comprises a plurality of louvers utilizing a number of fins, a discharge outlet actuator for controlling the fins, and a controller for determining that the environmental conditions of the vehiclular cabin are in either, a cool-down state wherein a cabin temperature in the vehicular cabin is excessively higher than a target cabin temperature, a steady state wherein the cabin temperature is essentially equal to the target cabin temperature, or a transient state between the cool-down state and the steady state. The controller controls the discharge outlet actuator so as to vary the discharge mode of the conditioned air discharged from the discharge outlets in one of three discharge modes in response to the environmental conditions. The controller controls the discharge mode such that the occupant in the vehicular cabin can feel suitably cool under the environmental conditions in the vehicular cabin which is momentarily changed.

    • A clock frequency divider circuit for producing signals of a desired frequency (of, for example, 1.024 MHz) in response selectively to input clock pulses of two or more different predetermined frequencies, wherein control pulses are produced from and in synchronism with the input clock pulses and are fed to a frequency division network including two master-slave "D" flip-flop circuits adapted to produce a first predetermined fraction of the frequency of the control pulses in response to input clock pulses of a first frequency (of, for example, 2.048 MHz conforming to CCITT Recommendation standard) or a second predetermined fraction of the frequency of the control pulses in response to input clock pulses of a second or third frequency (of, for example, 1.536 MHz or 1.544 MHz conforming to T-1 standards). Signals with a frequency corresponding to such a first or second predetermined fraction are fed to a frequency selector network in which the frequency fraction is multiplied by a first or second predetermined multiple to achieve the desired frequency.

    • An insulated-gate type field-effect transistor (MOST) analog switching circuit which has improved capacitance compensation to provide high speed, low transient noise operation and which is readily implemented as an integrated circuit comprises a switching MOST coupled between an analog signal input terminal and an output terminal, and two series connected compensation MOSTs which are substantially the same size as the switching MOST. The compensation MOSTs are connected so as to function as compensation capacitors and the series circuit is connected between the output terminal of the switching circuit and a source of pulses of opposite phase to the switching pulses applied to the gate of the switching MOST. The compensation MOSTs can be interconnected in different ways to form the series circuit, but gate-to-gate interconnection is preferred where the junction capacitance between the source-drain and substrate is not negligible with respect to the gate capacitance. Capacitor operation of the compensation MOSTs can be achieved by short-circuiting the source and drain of each MOST together, or by connecting the source and drain, respectively, of each MOST to the source or drain of other MOST.
    • 一种绝缘栅型场效应晶体管(MOST)模拟开关电路,其具有改善的电容补偿以提供高速度,低瞬态噪声操作并且容易地实现为集成电路,包括耦合在模拟信号输入端和 输出端子和两个串联的补偿MOST,其大小与开关MOST大致相同。 补偿MOST连接起来作为补偿电容器,并且串联电路连接在开关电路的输出端子与施加到开关MOST的栅极的开关脉冲的相位相反的脉冲源之间。 补偿MOST可以以不同的方式互连以形成串联电路,但是栅极至栅极互连是优选的,其中源极 - 漏极和衬底之间的结电容相对于栅极电容不可忽略。 补偿MOST的电容操作可以通过将每个MOST的源极和漏极短路在一起,或者将MOST的源极和漏极分别连接到其它MOST的源极或漏极来实现。
