Patent JP-H0118398-B2 (JP)
IPC: H02P8/02
Filed: 1980-09-09
Abstract: An electronic timepiece comprises a stepping motor driven by alternating square wave pulses, and a detector circuit for detecting the non-rotation condition of the rotor. The detector circuit is responsive to motor load current and looks for the presence of points A, B or C in the load current waveform curve 3 Fig. 1 which indicates normal rotatable condition. If the rotor has missed a step or the load is excessive such that these points are not detected, the load current being as waveforms curves 1, 2 Fig. 1, the detector circuit output is used to progressively adjust drive pulse duration accordingly as in Fig. 7 arrangement, or to make up for lost steps as in Fig. 6 arrangement. The detector circuit comprises an amplifier 24 including MOS transistors 1, 2 (eg as in Fig. 2) and a capacitor 3. Voltage applied to the amplifier is proportional to and has the same waveform as the motor drive current. <IMAGE>

Abstract: PURPOSE:To obtain a reproduced picture having a sufficient transmission concentration by providing the first recording mode for a reflective component part to be recorded and the second recording mode for a photopermeable component part to be recorded and carrying out recording in either of the corresponding mode. CONSTITUTION:A recording head is driven by a clockphi moving at a fixed period to discharge ink droplets to the surface of a component part to be recorded. In an ordinary paper recording mode, the head is driven every three pulses of the clockphi (time T1, T2, T3...). In the meantime, in a film recording mode, printing is carried out an T1, T2, T3... and at the same time, printing is performed at T1', T2', T3'... As a result, dots D1', D2', D3'... are printed in such a way that these dots overlap dots D1, D2, D3... Thus ink is discharged twice to the same picture element and it is possible to obtain a reproduced picture at almost the same transmission concentration as that of an ordinary paper against film.

IPC: G02F1/39

Abstract: A fiber optic amplifier utilizes a crystal fiber of laser material to bidirectionally amplify light signals. This amplifier permits the application of both pumping illumination and the signal to be amplified to the end of the crystal fiber to avoid the disadvantages inherent in side pumping this fiber. End pumping is accomplished by taking advantage of the slow spontaneous fluorescence of the laser crystal to sequentially apply the pumping illumination and then the signal to be amplified to the crystal. This sequential application of signals is made possible through the use of a switchable coupler which allows light to be selectively coupled from either of a pair of input optical fibers to a single output optical fiber which is coupled to the crystal fiber. The pumping illumination is initially supplied to the crystal fiber to invert the ions within the crystal. Once these ions are inverted, the coupler is switched to permit the application of the signal to be amplified to the crystal, and the application of pumping illumination is temporarily discontinued. The signal to be amplified propagates through the crystal to stimulate emission of coherent light from the laser material resulting in amplification of the signal. When this amplification process is complete, pumping illumination is again applied through the switch to the crystal fiber.

Abstract: A metal can end with a tear-open plastics closure in which the closure has a plug part (14) fitting into an aperture (11) in the can end, a rim (17) surrounding the plug part, an d a pull tab (15), wherein a groove (22) extends across the plug part (14) and aligned grooves (24,25) or interruptions extend across the rim (17) to provide a hinge line allowing the tab (15) and the adjacent portion (23) of the plug part to pivot upwardly to provide venting of the can in a first stage of opening before full opening of the closure in a second stage. The closure (12) is of the kind which is moulded on to the can end (10) so as to totally enclose a downturned flange (16) around the periphery of the aperture (11), and to be capable of being sheared against the flange on opening, and the residual thickness of the plastics material below the flange (16) is greater in the main portion than in the vent portion (23) of the closure to provide a temporary arrest after venting. The plug part (14) is stiffer than the metal of the can end so that doming of the can end under internal pressure is concentrated in the metal and the pull tab (15) extends at an angle to the can end surface, rendering it easier to grasp for opening the aperture. A second hinge line may be provided at the far end of the closure, with a further increase in residual thickness, so that the closure can be retained on the can end while being hinged out of the way for pouring.
