A sample and hold circuit for holding a sampled voltage, having a first MOS transistor for sampling the input voltage and a holding capacitor for holding the sampled voltage, and further comprising a second MOS transistor. The source and the drain of the second transistor are both connected to the output terminal of the circuit. The gate-source capacitance of the first MOS transistor is the sum of the gate-source and gate-drain capacitances of the second MOS transistor. When a voltage for turning on or off the first MOS transistor is applied to the gate of the first MOS transistor, the second MOS transistor is turned off or on respectively. The effect of this invention is that the sampled voltage can be held constant while turning off the first MOS transistor.

An offset compensating circuit is disclosed. The offset compensating circuit is inserted in a negative feedback loop of a circuit to be compensated and includes an integration circuit. The integration circuit includes a switching means mechanism and a switched capacitor type integrator. Said switching means mechanism produces either a positive reference voltage or a negative reference voltage in accordance with the polarity of the output signal of the circuit to be compensated. The positive or negative reference voltage is applied to the switched capacitor type integrator, which produces a compensating voltage signal to be combined with the input signal of the circuit to be compensated.

An object of the present invention is to provide a guidewire having high safety and improved flexibility and rotation followability. This guidewire has an inner coil that surrounds a distal side portion of a core shaft, and an outer coil that surrounds the inner coil and the distal side portion of the core shaft. A front end of the outer coil and a front end of the inner coil are joined to a tip of the core shaft by a tip plug. Further, the guidewire has a coil joint that joins only the outer coil and the inner coil to each other. With this configuration, the flexibility of the inner coil is maintained. Moreover, rotation of a proximal side of the guidewire is transmitted to the inner coil not only from the core shaft but also from the outer coil. This leads to improvement in rotation followability.

Disclosed is a directional bar-type antenna which comprising a plurality of bar-shaped antenna elements including a core and a coil wound around the core. The first bar-shaped antenna element is disposed at a position of a mirror image of the second bar-shaped antenna element with respect to the core of the third bar-shaped antenna element. The first and second bar-shaped antenna elements is positioned such that one end of each of the first and second bar-shaped antenna elements is close to the third bar-shaped antenna element, and the other end is far from the third bar-shaped antenna element. In the present invention, a winding direction of the coil of the first bar-shaped antenna element is preferably identical to that of the coil of the second bar-shaped antenna element, and is opposite to that of the coil of the third bar-shaped antenna element. The directional bar-type antenna of present invention can meet a need for providing asymmetrical directionality in a forward-rearward direction of an antenna for use in a specific system, such as a keyless entry system, and solve a problem in terms of cost and external appearance, in a technique of partially surrounding a bar-type antenna by a shielding member, in view of difficulty in freely controlling directionality of an antenna in an induced electromagnetic field domain, and a need to allow the bar-type antenna to have a difference between respective receiving sensitivities in forward and rearward directions in the induced electromagnetic field domain (while facilitating a reduction in size and cost).
