摘要： To eliminate influence of air bubbles introduced into an ink jet head along with ink, an ink circulation pathway is provided which includes first to third ink channels. The first ink channel is connected between the sub-tank and a buffer tank to supply ink in the sub-tank to the buffer tank. The buffer tank is provided in a head unit to be mounted on an ink jet printer body. The second ink channel is connected between the buffer tank and the sub-tank. Any air or bubbles that have accumulated at the upper portion of the buffer tank can be discharged to the sub-tank by the pumping operation of a buffer purge pump disposed in the second ink channel. The third ink channel is connected between an ink cartridge and the sub-tank, and ink stored in the ink cartridge is supplied to the sub-tank through the third ink channel by the pumping operation of a ink supply pump disposed in the third ink channel when the ink stored in the sub-tank has gone below a certain fixed amount.

摘要： An optical surface roughness measuring device for measuring roughness of a surface of a subject in a non-contacting manner. The apparatus includes a laser device for producing two linearly polarized laser beams which has mutually perpendicular polarization planes and different frequencies, and an optical device adapted to receive the two linearly polarized beams, converge one of the two laser beams so as to irradiate a first reading spot on the surface of the subject, convert the other of the two laser beams into parallel rays of light, and irradiate a second reading spot on the surface with the parallel rays of light of the other laser beam such that the second reading spot is aligned with the first reading spot and has a diameter sufficiently larger than that of the first reading spot. The surface roughness is measured based on a detected change in a beat frequency of the two laser beams reflected by the first and second reading spots. Alternatively, the two beams may be converged by a converging lens device at two spaced-apart points of the subject surface. In this case, an optical device includes an arrangement for establishing an angle of inclination between the directions of incidence of the two beams upon the converging lens device.

摘要： The invention includes a suction cap that does not retain ink therein. The suction cap includes a cap member having a recess and a suction opening formed therein and a capillary force generating member disposed in the recess. When a recovery operation is performed for ink ejection using the suction cap, ink sucked from a nozzle flows downwardly from a tilt surface of the recess due to gravity and a suction force applied through the suction opening. The ink impinges a side face of a projection of the capillary force generating member, flowing into defined narrow spaces, due to the action of capillary force of the ink, and flowing toward the suction opening. The ink in the defined narrow spaces is discharged by the suction force applied through the suction opening to outside the suction cap.

摘要： A rotary encoder includes a laser device which emits a laser beam having beats caused by superposition of a parallel wave and a vertical wave, which have mutually different frequencies and whose oscillating surfaces are normal to each other. A part of the beating laser beam is led to a first detector where the beat frequency of the original laser beam is detected. The remaining laser beam is split into the parallel and vertical waves by a splitting/irradiating device, and the parallel wave is irradiated onto a predetermined position of the rotational member and is scattered or reflected upon Doppler shifting attendant to the rotation of the rotational member. The scattered or reflected parallel and vertical waves are led to a synthesizer where both waves are synthesized to provide a laser beam with beats. The synthesized laser beam is led to a second detector where the beat frequency of the laser beam after being Doppler shifted is detected. The thus detected beat frequency and the beat frequency detected in the first detector are supplied to an arithmetic unit. The arithmetic unit computes a rotational angle of the rotational member in accordance therewith.

摘要： An ink jet recorder includes a sub ink tank and a recording head which includes a manifold. The tank and the manifold are connected to an upstream supply tube and a downstream supply tube, respectively. The supply tubes can be connected by a first joint. The manifold and an upstream return tube can be connected by a second joint. The joints are fitted with filters, respectively, for removing foreign substances etc. from ink. The filters are so positioned that ink can flow upward through them. This makes it easy for the air in the ink flowing through the filters to pass buoyantly through them. Because no air stays at the filters, it is possible to increase their effective areas, and therefore secure the quantity of ink flow necessary for printing.

摘要： An optical system for producing an optical output having a beat frequency. The shifter has a beam splitter for splitting a laser radiation generated by a laser source, into a first and a second laser beam, and includes an acoustooptical modulator for deflecting the first laser beam and thereby changing the frequency of the first laser beam. The shifter further has an optical-path changing device such as a convex lens or parabolic reflector for changing an optical path of the first laser beam deflected by the acoustooptical modulator, into parallelism with the optical axis of the changing device. The focal point of the optical-path changing device is located at a point of emission of the deflected first laser beam. A mixer is provided for mixing the deflected first laser beam with the second laser beam, thereby causing an interference between the first and second laser beams, to produce a beat frequency equal to a difference between the frequencies of the first and second laser beams.

摘要： A recorder like an ink jet printer includes a head unit, which includes recording head and a head holder. Intermediate members are screwed to the holder. Each of the recording heads is bonded to one of the members and has a number of ink ejection nozzles. After the unit is assembled, one of the heads may be found to be defective. Even in this case, it is possible to remove only the defective head and the associated member, fit a new intermediate member to the holder, and bond a new recording head to the new member with the nozzles of this head aligned with the nozzles of the other heads. The intermediate member has a hole engaging with part of the head with play for positioning the head relative to the holder.
