Abstract: A mechanically coupled electrical filter comprises two longitudinal mode vibrators 20a, 20b mechanically coupled together by a coupler 52. Each of the vibrators 20a, 20b is set up with a piezoelectric ceramic member 11a, 11b and constant modulus alloy members 21a, 21a', 21b, 21b' mounted separately on its top and bottom surfaces. The two constant modulus alloy members 21a, 21a'; 21b, 2Tb' on each ceramic member 11 a, 11 b have the same configuration, a frequency-temperature characteristic opposite to that of the piezoelectric ceramic member 11 a, 11 b, and have their centres aligned with the centre of the piezoelectric ceramic member 11 a; 11b. Such configurations of the two longitud- nal mode vibrators 20a, 20b suppress higher order harmonic and spurious vibrations and so filter out these components. In use an electrical signal is applied across the alloy members 21a, 21a' of the input side vibrator 20a and results in its resonating at its fundamental frequency. This vibration is then mechanically coupled to the output side vibrator 20b with the result that it then resonates at substantially only its fundamental frequency. The mechanical vibration of the output side vibrator 20b generates an output electrical signal across its alloy members 21b, 21b' which is substantially only at the fundamental frequency.

Abstract: A spark control apparatus (1) for an internal combustion engine using a breaker point (3) or solid state (5) ignition to control current to an ignition coil (11). The waveform of the ignition signal from the ignition system is applied to a converter section (35) of the apparatus to convert the signal waveform to a predetermined waveform. A sensor (25) senses engine vibration and generate a representative electrical signal which a signal processor (41) processes to determine engine knock by comparing the peak and average values of the signal. A delay circuit (45) delays termination of current to the ignition coil and thus the ignition timing as a function of the comparison of the peak and average values of the control signal. When there is no knock, the timing slowly returns to normal. A driver (50) responds to current signals to control current to the ignition coil. The driver is shut off when the engine is not running to reduce current drain. A first transistor (Q12) switches on and off when the engine is running and is off when the engine is not running. A second transistor (Q13) turns off the driver when the transistor is on. A controller (Q17, C14, R48 and R49) controls this transistor to turn it on when the engine is not running. The controller responds to changes in operating states of the first transistor to switch the operating state of the second transistor.

Abstract: In a method of calling a portable unit from a base station through a radio control channel, a succession of terminating call signals is sent through the control channel from the base station to the portable unit for a first or restricted duration (T<sub>1</sub>) selected in consideration of a battery saving period of a battery saving operation carried out in the portable unit. Within the battery saving period, the portable unit is put into transient active and inactive states during a first time interval and a second time interval, respectively. Selection is made so that the first duration be longer than the second time interval to receive at least one of the terminating call signals within the first duration in the portable unit. The base station monitors an acknowledgement signal for a second duration (T<sub>2</sub>) after lapse of the first duration and interrupts the control channel when the acknowledgement signal is not received within the first and the second durations. In the portable unit, the battery saving operation is released when presence of the terminating call signals is detected by a squelch circuit.

Abstract: One of patterns (22) representative of instants along each TDMA frame is selected as a selected pattern (24) in response to a unique word detection pulse produced in a currentframe. With the unique word detection pulse used as a write pulse (27), a memory (25) memorizes the selected pattern as a memorized pattern in a memory cell accessed by one of burst identifying flags which identify time slots in the current frame, respectively. The memorized pattern is produced as a read-out pattern (28) when accessed by the burst identifying flag which corresponds in a next succeeding frame to the above-mentioned one burst identifying flag. A calculator (31) produces offset representing patterns (32). Upon coincidence of each read-out pattern and one of the offset representing patterns, a comparator (33) produces a receive position predicting pulse predictive of a position of a unique word detection window in the next succeeding frame. The write pulse is preferably obtained by giving the unique word detection pulse a delay which is equal to a predetermined fraction of each time slot. The offset representing patterns represent the respective instants plus an offset which is equal to a duration of each frame minus a half of a duration of each unique word detection window.

Abstract: A vacuum pump for a desoldering iron gun which comprises a cylinder closed at one end with a piston movable in the cylinder, and means including a valve connecting the closed end of the cylinder to the gun. A spring normally urges the piston away from the closed end of the cylinder, and drive linkage connects the piston to a motor for moving the piston toward the closed end of the cylinder against the urging of the spring. Latch means holds the piston in position adjacent the closed end of the cylinder. Trip means for releasing the latch is operated by the same motor. Operation is initiated by a switch on the gun that starts the motor, causing the trip mechanism to release the latch, and the spring to force the piston away from the closed end to produce a partial vacuum. The motor continues to run through its cycle, again compressing the spring and moving the piston back to its latched position.
