Abstract: To permit the advantage of low-noise operation, obtainable by using links of respectively different lengths in a sprocket chain built in the triple side bar arrangement, while providing longitudinal guidance to the links and preventing interference of longer links with shorter links, some of the chain links (1, 10) have the side bars (1a, 10a) formed with a projecting nose (12, 14), positioned on at least one end portion of the respective side bar of the link, the projection extending towards the next sequential chain link, with a maximum extent up to the joint piece or rocker element (3) interconnecting the links together.

Abstract: A polarization-independent optical isolator comprises three Faraday rotators and four birefringent elements. An optical arrangement of these elements is determined on the basis of the appropriate values derived from the analysis for polarization-independency. A transmission loss characteristic, which is most important in practical use of the optical isolator, is maintained at an excellent level even in presence of variation in temperature and wavelength and in presence of fluctuation in working precision. Deterioration of various isolator properties can be avoided.

Abstract: An invertor-controlled generator unit is connectible with at least one other generator for parallel operation. The invertor-controlled generator has an invertor circuit which performs switching operation to convert a direct current power into an alternating current power based on a reference sinusoidal signal. Voltage and current of the alternating current power from the invertor circuit are detected. A difference in phase between the detected voltage and current is detected, and a signal indicative of the phase difference is formed. A reference pulse signal is formed in response to the signal indicative of the phase difference for varying the frequency of the signal indicative of the target output waveform in a manner such that the phase difference is decreased.

Abstract: Method for the automatic generation, from a system or protocol specified as an FSM, of unique test sequences in order to establish whether or not the implementation is in a particular state. On the basis of the FSM a table comprising legal possibilities is generated for each state, as well as a series of tables comprising legal impossibilities for the remaining states. Unique test sequences are found by selecting those IO sequences which occur in the "possibilities table" and in all the "impossibilities tables". If required, the shortest UIO sequence can be selected therefrom.

Abstract: In a ringing signal control circuit for controlling supply of a ringing signal from a ringing signal generator to a subscriber's line in response to a call signal destined thereto, a switching element is repeatedly switched to connect the ringing signal generator to the subscriber's line under control of a switching signal from a switch controller. In order to suppress a surge voltage due to connection and disconnection of the subscriber's line for the ringing signal generator, a memory stores a time data signal representative of a transition time from a reference voltage level to an optimum voltage level for the subscriber's line. The optimum voltage level is the level at which the connection and disconnection can be carried out without generation of the surge voltage. A voltage comparator compares the ringing signal with the reference voltage to produce a coincident signal.

Abstract: A correction device for correcting the deviation of light beams of a primary scanning direction used for an image forming apparatus in which a plurality of light beams are simultaneously scanned on a recording medium in the primary scanning direction so that a plurality of lines are simultaneously recorded. A plurality of beam detectors, the number of which corresponds to the number of beams of light, are disposed in a scanning region in parallel with the primary scanning direction. Only one light beam is incident upon each beam detector, and a difference of detection time between the plurality of beam detectors is detected by a same beam detection interval detector. A different beam detection interval detector detects a time difference between detection of different light beams are detected.

Abstract: An apparatus of this invention is designed to output document data including ruled line data upon proportionally arranging the data on one page to prevent the disruption of the relationship between the column and row positions of the ruled line data on the page. A document arranging section sequentially changes the character sizes stored in text and table format memories to develop document data of a designated page in a layout development memory. If the developed document data occupies 3/4 or more of a printable region, the data is printed according to the current format by a printing section. If the character size exceeds a limit value set in a format table before the area of the data becomes 3/4 or more of the printable region, the line spacing and the upper margin are sequentially changed in the same manner. If a ruled line causes overflow when the character size of ruled line data is changed, the character size is decreased by one step to prevent line feed of the ruled line.

Abstract: An amorphous silicon hydride thin film is deposited on an insulating body by a plasma CVD method, and is then heated for dehydrogenating the amorphous silicon thin film so that a dehydrogenated amorphous silicon thin film containing hydrogen of 3 atomic % or less is formed. The insulating body may be an insulating substrate (such as a glass substrate) alone, or a combination of an insulating substrate with an intermediate insulating base layer thereon. Impurity ions are injected into the dehydrogenated amorphous silicon hydride thin film to form source and drain regions. Excimer laser beams are applied to the dehydrogenated amorphous silicon thin film, thereby polycrystallizing the amorphous silicon thin film into a polysilicon thin film and activating the injected impurity ions.

Abstract: A lighting device for a vehicle includes a mechanism for preliminarily fitting a lens to an extension before it is firmly fitted to a housing of the lighting device. To assure that a lens fitting operation is easily achieved at a reduced cost, a fitting hole is formed through an auxiliary foot portion extending from a housing fitting foot portion of the lens. A boss in the form of a tapered pin-shaped projection extends from the extension at the position corresponding to that of the fitting hole. In addition, a flange portion is formed at the upper end of the extension. The lens fitting operation is performed by inserting the boss into the fitting hole while the flange portion is placed on the upper surface of one of the side walls defining a lens receiving groove formed at the upper end of the housing of the lighting device.
