摘要:
This invention relates to a printing apparatus, printhead, and cartridge type discrimination method capable of achieving high-reliability, high-quality printing by effectively utilizing a memory element incorporated in the printing apparatus and dealing with an error by all the building components of the printing apparatus. According to this invention, in a printing apparatus which prints on a printing medium with an ink cartridge and inkjet printhead mounted on a carriage, mounting of the ink cartridge on the carriage is detected, identification information is read from the non-volatile memory of the ink cartridge, and it is discriminated on the basis of the identification information whether or not the mounted cartridge is a certified one for the printing apparatus.

A ceramic heater which includes: a cylindrical substrate including an insulator; a resistor provided in one end side of the substrate; a pair of lead parts provided in the substrate, connected to the resistor and extending to an opposite end side of the substrate; and a pair of electrode parts exposed to a surface at an opposite end side of the substrate and connected respectively to the lead parts. Both lead parts are made of the same material as both electrode parts. An axial cross-sectional area of the electrode part is equal to or larger than a cross-sectional area of the lead part in a direction perpendicular to an axis of the ceramic heater.

In the present invention, an episulfide compound having, in one molecule, at least one epithio structure represented by the following Formula 2: wherein R5 is C1–C10 hydrocarbylene or single bond, R6, R7 and R8 are each independently C1–C10 hydrocarbyl or hydrogen, Y is O, S, Se or Te, p is an integer from 1 to 5 and q is an integer from 0 to 5, is polymerized in the presence of a halide of a 13–16 group element of the long periodic table and/or a polymerization regulator represented by the following Formula 1: wherein R1, R2 and R3 are each C1–C10 hydocarbyl or hydrogen, R4 is C1–C10 hydrocarbylene or single bond, X is F, Cl, Br, I, As, SH, OH, C1–C10 alkoxyl, C1–C10 alkylthio, or C1–C10 mercaptoalkythio, and m is an integer from 1 to 5, to produce a cured resin suitable as an optical material. By using the polymerization regulator, the polymerization rate of the episulfide compound can be suitably regulated to obtain a cured resin with less defect. By using the halide, the increase in the viscosity of the starting composition during the storage or the casting operation can be prevented.

This disclosure relates to a driving and water pouring control device for dental air-drive handpiece. According to the control device, there is incorporated a water pouring on-and-off valve means into an air feed passageway for driving a turbine so as to close and open the valve means by using part of air inside the passageway and to concurrently provide the valve means with a function of preventing water from dropping when pouring of water is stopped. The disclosure also relates to a device capable of compactly assembling therein device members.

The disclosure relates to a dental treatment chair which contains in its backrest a dispensing controller for compressed air and water to be distributed to the dental instruments of the chair; the controller includes a distributing block for air and water, air-pressure-operated on-off valves, and couplings to connect flexible connecting pipes connected to the instruments to the supply source side. The chair can reduce the number of compressed air and water pipes leading from the seat body to the backrest of the chair and can diminish the distance of piping between the dental instruments and the dispensing controller to reduce passage resistance.

This disclosure relates to a device for controlling tilting of headrest of treatment table such as for treating the teeth, eyes, nose and the like. The device makes it possible for an operator to tilt the headrest efficiently by such very simple manipulation as to enable backward and rearward tilting of the headrest by pushing in a support shaft in one direction which is transversely incorporated into a headrest carrier or a backrest carrier and to retain the headrest in a desired position by releasing the pushing force of the support shaft in the position.
摘要:
A dental chair which comprises a seat, a back inclinable relative to said seat, first means for effecting inclination of said back, second means for pushing the front portion of said seat upward, and third means operable in response to overinclination of said back beyond the normal inclination thereof to drive said second means so as to raise the front portion of said seat relative to the rear portion thereof.
