Title: Ink jet recorder
Inventor: MURAYAMA YASUSHI
IPC: B41J2/165
Filed: 1988-12-30
Abstract: PURPOSE:To enhance efficiency of a recovering operation by making a wiping means for an ejecting surface of a head to serve also as a squeezing means for an ink ejected from the head, and squeezing out the ink absorbed by an ink absorber, simultaneously with wiping the ink off the ejecting surface, thereby refleshing the absorber. CONSTITUTION:When ink circulation under pressurization is finished, an ink absorber 3 maintained in contact with an ejecting surface of a head is again separated from the ejecting surface. In this condition, an ink is squeezed out of an ink absorber 3 by a squeezing member 5. The ink thus squeezed flows along an absorber guide 7 and a partition plate 8 to drop into a recovering container 2, from which it is led through an ink discharging port 13 into an ink discharging tank. Simultaneously with the separation of the ink absorber 3 from the ejecting surface and the squeezing of the absorber, a wiping blade 88 for the ejecting surface is driven to wipe out the ejected ink and refuse, adhered matter or the like remaining on the ejecting surface. The ink and the like thus wiped drop into the container 2, and is led therefrom into the tank. The ink absorber 3 thus squeezed by the squeezing member 5 recovers an absorbing capability thereof, thereby preparing for the next ink absorption. Thus, cleaning of the ejecting surface of the head and recovery of a nozzle having failed in ejection can be performed efficiently.

Title: Constant-voltage generating circuit
Inventor: NAKABAYASHI TAKASHI
IPC: G05F1/618
Filed: 1988-12-28
Abstract: PURPOSE:To prevent the circuit from being influenced by a fluctuation of a power supply voltage and a variation of an ambient temperature by compensating a fluctuation caused by a variation of an ambient temperature in the forward direction of a diode by a fluctuation of a gate - source voltage of a first field effect transistor (FET). CONSTITUTION:A source follower is constituted by connecting in series a diode D and resistances R4, R5 between the reference potential (ground) and a negative power source Vss, and connecting in series a first FET1 which is scarcely influenced by a temperature variation and a third FET3 which is greatly influenced by a temperature variation, and the cathode potential of the diode D is outputted to this source through a gate of a first FET1. A fluctuation caused by a variation of an ambient temperature of a forward voltage of the diode D is compensated by a fact that a drain - source current of a third FET3 is fluctuated by a variation of an ambient temperature and a gate - source voltage of a first FET1 is fluctuated. Also, a fluctuation of a power supply voltage scarcely exerts an influence on an inter-terminal voltage of the diode D and an operation of the source follower. In such a way, a stable supply voltage is always outputted.

Abstract: PURPOSE:To perform a good signal detection without being affected by the variation in the diameters and groove shapes of pits by detecting tracking errors by means of the phase difference between a reference pit and a phase difference pit arranged at a prescribed angle on a track. CONSTITUTION:On the track 2 in a servo area, the reference pit Pc is formed, and the phase difference pit Pd, which has the prescribed angle against the track 2 and at a fixed interval from the pit Pc, is formed.
