Abstract: A cue delay circuit for an ink jet printing system includes a state machine with sequenced logic circuits that generate buffered control signals; a counter that counts one of the buffered control signals to form a read address; and an adder that combines the read address to the cue delay value to generate a write address. A comparator compares the cue delay value to the read address to determine if the read address is greater than the cue delay value. A multiplexer receives the read and write address and one of the buffered control signals and forms a multiplexer output. The system includes a gate circuit that receives the latched comparator output and the RAM output signal forming a gated cue signal; and a logic circuit that sends a signal to the printing system.

Abstract: A first voltage detector detects whether the voltage of a secondary cell has reached to 1.2V and a first timer counts a time duration for which the voltage is equal to or above 1.2V. If the time counted by the first timer reaches one hour, a second timer starts counting time for one hour. An amount of charge accumulated in the secondary cell is displays after counting of the one hour by the second timer is over. As a result, an accurate display of the amount of charge accumulated in the secondary cell can be achieved.

Abstract: A timer circuit that utilizes the thermal runaway effect, and includes a switch, a resistor, a transistor and a protective device. The temperature of the transistor rises due to a phenomenon known as the thermal runaway effect, which causes the temperature of the transistor to rise while increasing current flow. This will eventually cause the protective device to activate. The time it takes to activate the protective device is predictable for a given transistor, therefore the circuit operates as a timer. In an alternate embodiment, a heat source is used. This heat source rises in temperature as current flows in the circuit. A heat sensor located near the heat source rises in temperature along with the heat source. A comparator compares the temperature from this heat sensor with the temperature of a heat sensor located further from the heat source. When there is a user-definable difference in temperature due to thermal diffusion between the two heat sensors, power to the transistor is disconnected.

Abstract: The motor driving a minute-indicator in a down counting operation which must count a finite duration is stopped when the terminal post of its control circuit is connected to "earth" potential by an electric line. A seconds-hand, rotating in synchronism with a minute-indicator, effects several revolutions during the counting operation.
