Title: Detecting device for rotating speed of internal combustion engine
Inventor: IKETANI MASAHIRO
IPC: G01P3/481
Filed: 1986-01-13
Abstract: PURPOSE:To easily set and adjust reference pulse width on the basis of which a noise is decided by counting noise removal based upon the pulse width from the supply of a pulse signal and inputting the counted value to a comparator when the counted value reaches an expected counted value. CONSTITUTION:A pulse signal (a) is outputted by an engine rotating speed sensor 1 and an FF 21 is set with the normal pulse signal of the signal (a). The FF 21 outputs a high-level signal (b) and a presettable down counter 22 counts down from a preset value according to the signal (b). When the counted value reaches zero, a trigger signal (c) is supplied to the comparator 23, which decides whether or not the level of the signal (a) is lower than a reference level and outputs a high-level signal (d) to a timer 4 when the signal (a) is the normal pulse. The counted value of the timer 4 is supplied to a computing element 5, which computes an engine rotating speed Ne. Then, even when an impulsive noise is mixed with the signal (a), the FF 21 is set, but the noise disappears at the output point of the signal (c), so the noise is removed.

Title: Pulse droplet bonder and manufacture of pulse droplet bonder
Inventor: ARAN JIYON MAIKERUZU
IPC: B41J2/045
Filed: 1988-01-11
Abstract: A pulsed droplet ink jet printer has relatively long thin ink channels extending in parallel between an ink manifold (13), and a nozzle plate (5) providing a nozzle (6) for each channel. Side walls (11) may be formed substantially entirely of piezo-electric material so as to be displaceable transversely into a selected channel on the application of an electric field. This transverse displacement produces an acoustic wave in the channel which results in the ejection of an ink droplet. The side walls may deflect in shear mode to a cross-section of chevron formation. Usefully, it is arranged that both side walls adjoining the selected channel are displaced inwardly of the channel to cooperate in droplet ejection. Under this arrangement, the channels are assigned alternately to first and second groups of channels, only one group of channels being capable of actuation at any one instant. The nozzles associated with the respective groups of channels may be offset so as to compensate for the time delay in actuation of channels in the first and second groups.

Title: Automatic correcting circuit for tracking offset of optical information recording and reproducing device
Inventor: NAKAJIMA HIDEO
IPC: G11B7/09
Filed: 1989-01-12
Abstract: PURPOSE:To make corrections substantially without any error by correcting an offset erasure signal based upon the position detection of an objective with a signal error depending upon the characteristics of a recording medium. CONSTITUTION:An offset quantity detecting means detects an offset quantity DELTAHv which varies depending upon the characteristics of the recording medium and a correcting means corrects variation Gv in the offset quantity varying depending upon the characteristics of the recording medium from the reference offset signal Fv detected by the detecting means and corrects the offset erasure signal. Therefore, even if the offset quantity varies owing to the characteristics of the recording medium such as a difference in the shape of the group of recording media in use, the offset erasure signal based upon an unequivocally determined objective position can be corrected by the variation Gv of the offset quantity. Consequently, the automatic correction of a tracking offset having no correction error can be realized.
