Abstract: The present invention utilizes a novel technique for coupling ultrasonic energy into an optical fiber that can be used within a blood vessel of patient's body. The present invention includes a transducer [44] which is precisely located on a thin slab of piezoelectric material [10] that generates ultrasonic acoustic surface waves [62] that propagate on the surface [13] or within the bulk of the slab [10]. The transducer [44] may be selected from a set of the many novel alternative configurations that are disclosed in the specification and illustrated by the drawings. The operating power and frequency of the present invention can be predetermined by altering the configuration of the transducers [44]. One or more optical fibers [32] are affixed to the thin slab [10] to ensure the maximum transfer of acoustic energy into the optical fibers [32].

Abstract: A system for detecting melt-adhesion of relay to check melt-adhesion of relay contacts. Fully interlocked relays or half-interlocked relays are connected in a number of two to operate under the same conditions, and the melt-adhered condition is detected from a signal condition in which make contacts and break contacts of the two relays are connected in series. In the half-interlocked relays (R1, R2), if the coil is turned off under the condition where a make contact (r12) is melt-adhered as a result of flowing current to the coil, the other contact (r22) remains open or stays on the make contact side. Under the condition where the break contact (r11) is melt-adhered, the other contact (r21) remains open or stays on the break contact side when the relay coil is turned on. Therefore, half-interlocked relays are used in a number of two under the same conditions, and the make contacts and the break contacts of the relays are connected in series to check the two signals in order to detect melt-adhesion of relays. Melt-adhesion of the fully interlocked relays can be detected in the same manner, too.

Abstract: A position detector which has a plurality of loop coils arranged in parallel with one another in the position detecting direction, and which is adapted to determine a coordinate value of position, which is designated by a position indicator having at least a coil, on the basis of the electromagnetic action between the position indicator and the position detector. One loop coil is selected simultaneously from each of a plurality of groups among a plurality of loop coils so that not less than a predetermined number of the relative positions of these selected loop coils do not become the same or symmetric in each group and over a plurality of groups. A loop coil on which the position indicator is positioned is determined among the loop coils on the basis of the pattern of a signal amplitude obtained by this loop coil selection. This makes it unnecessary to select all loop coils at the time of starting a position detecting operation, and serves to reduce the time required to determine the coordinate value. When the coordinate value is determined, the digital data corresponding to an arbitrary AC signal are converted into an analog signal, and a reception signal is sampled at a predetermined cycle to convert the signal into digital data. These digital data are subjected to predetermined computation to calculate amplitude and phase angle with respect to an arbitrary frequency component in the reception signal, whereby the concurrent use of a plurality of coordinate indicators is effected easily.
