Title: Alarm timepiece
Inventor: MAKUTA SHIYUNICHI
IPC: G04G13/02
Filed: 1984-03-29
Abstract: PURPOSE:To enable confortable awakening without causing any feeling of startling or physical disorder by starting the sounding operation of an alarm tone at the end of inhalation. CONSTITUTION:A breathing detector 16 outputs a breathing signal responding to physical changes in a body with breathing and a inhalation end detection circuit 24 detects the end timing of the inhalation from the breathing signal of the detector 16. Then, an alarm control circuit 44 invalidates the alarm start signal to the outputting of the first signal from the detection circuit 24 after an alarm starting signal is generated at the output B of an alarm mechanism 14. Now when a switch 52 is closed at the time t1, alarming is enabled and when the set time is reached at the time t2, an alarm start signal is produced at the output B and the output C moves to ''H'' to release the resetting of an FF50. But since the output G is ''L'', the output I of the FF50 is also ''L'' and the alarming will not be done. Moreover, when the alarm start signal is generated at the time t3 and the first detection signal is produced at the output G, the output I of the FF50 moves to ''H'' and an alarm tone is given from a circuit 54.

Abstract: PURPOSE:To print an image void of virtual image having warp streak and the like by a method wherein, a control part outputting a signal for commanding energizing heating current of printing part, a control part for energization which switches over the application of currents into dividing/batch systems the application of current to a thermal head being divided into a plurality of sets of the energizing command, and a control for energizing said switching over operation, are provided. CONSTITUTION:An energization signal 6 works in accordance with a key switching-over operations such as 'high' 'low' speeds issued by an operation of the operation part 7, and by the operation of a control part 12, an energization signal is issued to a printer part 5. At this instant, the magnitude of the current from a terminal 15 increases, and by the resistance of a current feeding route such as of thermal head and the like, the applied voltage decreases, and the calorific value at a heating resistor 18 lowers, also a printing density decreases, and according to the kind of the image, warp streaks are generated. In such a case, when a switch 13 is made 'ON' per circuit, and the operation part 7 is made 'low speed', this results in the application of the energization signal to each of the thermal heads 19-22, then the printing speed lowers; because the current from the terminal 15 from the terminal at the line gradation flows in a plurality of steps, the prevention of voltage decrease can be realize, and the generation of warp streaks hardly occurs.

IPC: F16C32/04
Filed: 1989-03-16
Abstract: PURPOSE:To enable a speed increase in a driving circuit by allowing an electric current smaller than an offset signal to flow in an electromagnet continuously even if summed value consisting of a position control signal for notifying the position of a rotary body and an offset signal is less than zero so as to prevent the generation of reverse electromotive force of the electromagnet. CONSTITUTION:A clipper circuit 3 cuts at a negative constant level, a signal-Sc which is an inversion of an added signal Sc consisting of the reversed signal -Sa of a position control signal Sa and the reversed signal -Sb of an offset signal Sb and sends the cut output signal Sd to an addition circuit 4. The addition circuit 4 adds a constant signal to the output signal Sd and outputs an electromagnet control signal Se which is in a shape of -Sc cut at a positive constant level. As a result, a transistor 5 is always turned on and electric current is always flowing through an electromagnet 1 so that the generation of reverse electromotive force of the electromagnet 1 due to the switching action of a driving circuit 2 is prevented. Consequently, the oscillation of the driving circuit 2 can be hardly generated so that a speed increasing a driving circuit becomes possible.
