摘要:
A semiconductor device in which shield wiring is arranged between the semiconductor substrate and the power source wiring for supplying the power source potential or ground potential. Noise, as represented by variations in the potential of the semiconductor substrate, is substantially prevented from transferring to the aforementioned power source wiring by the shield wiring. In one aspect, shield wiring 1 is arranged between Vss wiring for supplying potential to the various circuits on the semiconductor substrate and substrate 7. This shield wiring 1 is connected to grounding lead frame 18 via M1 intra-chip wiring 4, M2 intra-chip wiring 5, connecting part 40, bonding pad 3 and bonding wire 8. Since the coupling impedance between shield wiring 1 and substrate 7 (due almost solely to the electrostatic capacitance Css) is large, and coupling impedance between Vss wiring 2 and substrate 7 (due almost solely to the junction capacitance D) is low, the noise caused by variations in the potential of substrate 7 is transferred to shield wiring 1, while it is not appreciably transferred to Vss wiring 2.

A paint-out shape display method and an apparatus in a numerical control apparatus judges whether the inside of basic shapes divided for each shape element should be painted out or erased and in turn combines those basic shapes, thereby enabling a cross sectional shape of a rotating body to be displayed accurately. The cross sectional shape of the rotating body can be displayed properly, easily and at a high speed, and therefore the efficiency of a series of machining operations, beginning with program test, is greatly improved and a reduction in cost can be achieved.

A sense amplifier circuit is described for switching plural inputs at high speed. At least two transistors for providing at least two true input signals are connected in parallel and have their source terminals connected to a common node from which an output signal may be read. Similarly, at least two other transistors for providing the inverse of the true input signals are connected in parallel and their source terminals are connected to another common node from which an inverse of the output signal may be read. The common nodes are then precharged to the same voltage. True and inverse input signals are applied to their respective transistors through transfer gates where all the true input signals are greater than their respective inverse signals. Therefore, the on-resistance of each of the transistors to which a true input is applied have a higher on-resistance than the associated transistors to which an inverse input is applied. Current flow then rapidly decreases through the transistors transmitting the inverse input signal as current is switchably applied to the transistors transmitting the true input signals.

An AFC circuit is employed in a television signal receiving apparatus which comprises a tuner having a local oscillator and a mixer for mixing a received high-frequency video signal and an output local oscillation frequency signal of the local oscillator so to frequency-convert the received high-frequency television signal to an intermediate frequency signal, and a tuning voltage generating circuit for generating a tuning voltage responsive to a desired receiving channel which is selected so as to apply the tuning voltage to the local oscillator of the tuner. The AFC circuit comprises a frequency discriminating circuit for frequency-discriminating an output intermediate frequency signal of the tuner, a lowpass filter supplied with an output signal of the frequency discriminating circuit, and a limiter circuit supplied with an output signal of the lowpass filter, for limiting the voltage level of the output signal of the lowpass filter depending on the desired receiving channel. The local oscillator receives an output signal of the limiter circuit. The limiter circuit performs a limiting operation in each receiving band when receiving a channel in which a change in the local oscillation frequency is large with respect to a change in the tuning voltage.

Each of control rods inserted in the core of a nuclear reactor is coupled to a control rod driving apparatus for moving the control rod in an axial direction by a coupling mechanism including a gripper formed at a lower end of a driving extension shaft adapted to be driven by the control rod driving apparatus, and a finger mounted at an upper end of the control rod for engagement with the gripper. A cam is located in the interior of the driving extension shaft for bringing the gripper and the finger into and out of engagement with each other for coupling and uncoupling the control rod and the control rod driving apparatus.
