Title: Vibrator unit
IPC: H01L41/053
Filed: 1976-12-21
Abstract: A vibrator unit for use in a timepiece comprises a vibrator mounted within a ceramic case. A glass lid is airtightly sealed to the ceramic case by means of a soldering washer soldered between opposing surface portions of the lid and case. The soldering washer consists essentially of 90Sn-10Au solder alloy which enables formation of the airtight seal at lower and/or shorter soldering temperatures than would be the case with conventional solder alloys thereby avoiding an increase in the equivalent impedance of the vibrator unit which would otherwise occur. As the equivalent impedance can be maintained at a low value, the vibrator unit can therefore be made smaller without adversely affecting the equivalent impedance which is maintained below 350 K OMEGA .

Abstract: 1324721 Electro-medical apparatus AMERICAN OPTICAL CORP 16 Nov 1970 [18 Nov 1969] 54346/70 Heading G1N [Also in Division H3] Apparatus for detecting the occurrence of a number of events in a given time interval e.g. the number of premature heart beats in a minute, comprises a plurality of timers for timing the interval, means for activating an inactive timer in response to each event and means for detecting activation of all the timers. The circuit described detects the occurrence of five such beats in a "running" minute i. e. within a minute of any one beat. As shown in Fig. 1, the first beat activates a first timer 10 which throughout its timing interval is unresponsive to any further pulses. Its output acts through a delay to enable a gate 18 so that if a further pulse beat occurs during the interval the second timer 11 is activated. Likewise if four beats occur within the interval timers 12 and 13 are activated and if a fifth occurs within the interval the gate 21 is open and the beat passes through all gates 18, 19 20 and 21 to set a bistable circuit 23 and operate an alarm. If five beats do not occur within the interval the next pulse operates the first timer which has become inactive so that a new timing period for five pulses commences. Reset of the circuit is effected when the initiating switch 26 is made. In Fig. 4 (not shown) the timers are arranged in a ring, the beats activating the first inactive timer after the last one to be activated. A gate (82) senses the simultaneous inactive condition of all the timers and directs the next beat to a pre-selected one (70) in the ring. The timers may comprise a bistable circuit 41, 42 (Fig. 2) which is set in response to a pulse whereby a unijunction transistor is fired after a delay determined by C.R. circuit 45, 47, the firing effecting reset of the bistable circuit.
