摘要:
Systems and method of maintaining a uniform temperature distribution in an inkjet head. The inkjet head includes a plurality of ink channels that jet droplets of a liquid material onto a medium using piezoelectric actuators. A temperature controller includes a non-jetting pulse generator that provides non-jetting pulses to one or more of the piezoelectric actuators to generate heat. The non-jetting pulses cause the piezoelectric actuators to actuate without jetting a droplet from its corresponding ink channel.

Ink port adapters for inkjet heads. In one embodiment, the ink port adapter includes two hose fittings for connecting to hoses, and four openings that align with four ink ports of an inkjet head. The adapter includes one ink path that connects one of the hose fittings to two of the openings, and another ink path that connects the other hose fitting to the other two openings.

Systems and methods of mitigating the effects of crosstalk in an inkjet head. An inkjet head has ink channels that jet droplets of a liquid material using piezoelectric actuators. Drive waveforms provided to the piezoelectric actuators include jetting pulses that cause activation of the piezoelectric actuators to jet the droplets from the ink channels. When crosstalk exists between the ink channels of the inkjet head due to the piezoelectric actuators, the amplitude of the jetting pulses are modified to mitigate the crosstalk between the ink channels.
摘要:
Ink port adapters for multi-color inkjet heads. In one embodiment, the ink port adapter includes two hose fittings for connecting to hoses, and four openings that align with four ink ports of a four-color inkjet head. The adapter includes one ink path that connects one of the hose fittings to two of the openings, and another ink path that connects the other hose fitting to the other two openings. The adapter therefore converts the four-color inkjet head into a two-color inkjet head.

Provided is a vinyl chloride resin composition having superior heat resistance, colorability and processability without using a heavy metal stabilizer such as lead.The present invention relates to a vinyl chloride resin composition which comprises, in addition to a vinyl chloride resin, (a) an organic acid calcium salt, (b) an organic acid zinc salt, (c) an organic acid potassium salt and (d) a polymer of alkyl ester of C4 to C10 acrylic acid or methacrylic acid, the polymer having a number average molecular weight of 1,000 to 4,000. Further, the present invention relates to a vinyl chloride resin composition which comprises, with respect to 100 parts by mass of the vinyl chloride resin, 0.01 to 5 parts by mass of the aforementioned component (a), 0.01 to 5 parts by mass of the aforementioned component (b), 0.001 to 1 parts by mass of the aforementioned component (c) and 0.05 to 10 parts by mass of the aforementioned component (d).
摘要:
An electric power steering system includes an overheat protection current value arithmetic unit that computes an overheat protection current value to which a current flowing into a motor is limited, and an overheat protection control unit that limits the current, which flows into the motor, on the basis of the computed overheat protection current value, suppresses heat dissipation caused by the current flowing into the motor, and thus protects onboard equipment. Information relevant to the computed overheat protection current value is stored. Whether a newly computed overheat protection current value is abnormal is decided based on comparison of the newly computed overheat protection current value with the stored information relevant to the overheat protection current value.

In a vacuum cleaner which is an example of an upright floor surface treating apparatus, a suction nozzle is provided forward relative to a lower portion of a body section such that an angle of a lower surface (Su) is changed, and a handle is attached to an upper portion of the body section. A steering wheel which determines a movement direction (M) is provided relative to the lower portion of the body section, and the handle and the steering wheel are coupled together by means of a steering coupling section including a handle shaft, a steering wheel adjustment shaft and a rotation transmission section. In this configuration, without using a complicated configuration, a direction of the suction nozzle can be easily changed without moving the entire body section.
摘要:
A bag formed of a sheet material adapted to be filled with contents and opened at the top for taking out the contents. The bag has fused joints along the lateral edges thereof. A plastically deformable wire-like member is attached inside the fused joints over a length from the output opening side portion to the body portion.

Processes for preparing 1-benzyl-4-[(5,6-dimethoxy-lindanon)-2-yl]methylpiperidine (donepezil), which is useful as an intermediate for medicines, and for producing 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidine hydrochloride (donepezil hydrochloride), which is useful as a medicine. The process for donepezil hydrochloride production comprises catalytically hydrogenating the compound represented by the structural formula (III) [1-benzyl-4-[(5,6-dimethoxy-lindanon)-2-ylidene]methylpiperidine] with a Raney nickel catalyst under mild conditions and subsequently treating it with hydrochloric acid. Thus, impurities are further diminished. The operations are simple and the process is suitable for industrial production.
