Abstract: PURPOSE:To decrease the support loss and then reduce the fluctuation of the support loss caused by the temperature variation, by increasing partially the film thickness of the electrodes on both surfaces each and then enclosing the contour vibration into the area near the part where the film thickness is increased. CONSTITUTION:Metal electrodes 22 and 22' are provided to the entire surface of the lower layer excepting edge parts g and g' on both surfaces of crystal plate 11. Then partial electrodes 221 and 221' shown by (l) are provided in the direction of length and nearly symmetrically in terms of nodes 33 and 33' on the upper layer of electrodes 22 and 22'. Accordingly, the electrode at the area of (l) has more thickness than the area near the center. As a result, the distribution of the extent of displacement decreases near nodes 33 and 33'. Thus when the supporting is carried out with a certain area at the area near nodes 33 and 33', the degree of the support loss can be decreased to the vibration. Furthermore, the fluctuation of the support loss caused by the temperature variation can also be reduced greatly.

Abstract: PURPOSE:To detect a sine wave of such low frequency as 1Hz or 16Hz for one rotation by providing a magnetic track in which the magnetic field intensity varies with respect to a ferromagnetic magnetoresistance element in a sine wave manner in accordance with the rotation of a magnetic drum. CONSTITUTION:A magnetic drum 1 is eccentrically mounted to a shaft 2. A coil 4 is connected with a direct current source 5, and is magnetized through the eccentric rotation of the drum 1. At this time, because of the change of a magnetization gap G in a sine curve, a track 6 is formed on the surface of the drum 1. The strength of the magnetic field is changed in the sine curve in the track 6. Then, the drum 1 is so mounted as not to be eccentric to the shaft 2, with an MR element 7 arranged adjacent to the track 6 with a gap (g). Magnetoresistances MR1 and MR2 the resistance value of which is changed by the magnetic field are provided inside the element 7. The resistance MR2 is arranged so that the resistance value is changed by a magnetic track 6A, while the resistance MR1 is so placed as not to be influenced by the magnetic track. This is the case of the magnetic track of 1Hz for one rotation and the magnetic sensor.

Title: Emitter follower circuit
Inventor: KOGA TAKASHI
IPC: H03F3/20
Filed: 1984-04-28
Abstract: PURPOSE:To eliminate a non-linear distortion of an output signal by letting flow a current of opposite phase to a fluctuating component of load current to an output terminal of a current mirror that sets a DC operation point of an emitter follower transistor. CONSTITUTION:A fluctuating component DELTAIL of current that flows in a load impedance circuit ZL depends on DELTAVi, and a fluctuating component DELTAIA of current that flows in an impedance circuit ZA depends on -DELTAVi. Accordingly, a fluctuating component DELTAI0 of collector current of a transistor (TR) Q13 depends on -nVi (n is current mirror ratio of a current mirror circuit consisting of the TRQ13 and a diode D12). Here, a fluctuating component DELTAIE of emitter current of an emitter follower TRQ11 becomes DELTAI0+DELTAIL, and when set to ZA=nZL, becomes DELTAIE=0. That is, the emitter current of the emitter follower TRQ11 becomes constant current irrespective of the fluctuating component DELTAIL of load current. Thus, the non-linear distortion does not occur in the output signal.
