摘要:
An ink supply apparatus for supplying ink from an ink tank to a recording head includes an atmosphere communication chamber that is connected to the ink tank, a first hollow tube that connects the atmosphere communication chamber to the outside air wherein one end is extended into the atmosphere communication chamber, and a second hollow tube that connects the atmosphere communication chamber to the outside air wherein one end is extended into the atmosphere communication chamber. The length of extension of the second hollow tube is different from the length of extension of the first hollow tube.

A temperature regulator regulates a temperature of a microchemical chip that has chemical reaction sections. The temperature regulator includes a temperature measuring unit and a thermoelectric element corresponding to each chemical reaction section. The temperature regulator further includes a heat conductor, a heat exchanging unit, and a temperature controlling unit that controls electric current to be applied to the thermoelectric element based on a temperature measured by the temperature measuring unit.

In a measuring space of the object (1), an essential measurement region (41, 61, 71, 81, 111, 131) having a center region of the measuring space and a plurality of peripheral measurement regions (42, 62, 63, 72, 82, 112, 132) which do not have any region overlapped with the essential measurement region are set. Then, the essential measurement region is combined with a selected peripheral portion of the plurality of the peripheral measurement regions to measure in a preceding manner a nuclear magnetic resonance signal from the object as data of the measuring space. The essential measurement region is combined with the peripheral measurement region of the plurality of the peripheral measurement regions which has not been selected in the preceding measuring step to measure a nuclear magnetic resonance signal from the object as data of the measuring space. Sequentially, the essential measurement region is combined with the peripheral measurement region having not been measured in a preceding measuring step to measure a nuclear magnetic resonance signal from the object. The data of the essential measurement region and the data of the peripheral measurement region thus measured is supplemented with the data of the peripheral measurement region measured in the preceding measuring step to generate data of the measuring space.
摘要:
An image forming method of the present invention begins with a first image transfer step for thermally transferring a first toner image from a first image carrier to a second image carrier contacting it. Subsequently, in a second image transfer step, the first toner image carried on the second image carrier and a second toner image newly formed on the first image carrier are thermally transferred to opposite sides of a recording medium substantially at the same time. Higher image transfer temperature is assigned to the second image transfer step than to the first image transfer step. Additionally, the second image carrier has a greater roughness than the first image carrier.

An image forming apparatus of the present invention includes a first and a second intermediate image transfer belt contacting each other to form a nip for secondary image transfer. While the nip is heated, a sheet is passed through the nip to thereby transfer toner images respectively formed on the first and second belts to opposite surfaces of the sheet at the same time. The nip is sized such that image transfer and fixation can be effected at temperature higher than the melting point or the softening point of toner by 5° C. to 50° C.
摘要:
In an inkjet recording apparatus in which a single ink supply path for hermetically sealing an ink tank and a recording head from the atmosphere is formed by connecting the ink tank to first and second hollow needles. When the ink tank is detached, the flow path is sealed in association with mounting and dismounting of the ink tank, thereby leakage of ink to the outside of the apparatus is prevented.
摘要:
In an image forming apparatus configured to electrostatically transfer a toner image formed on an image carrier to a recording medium with image transferring means of the present invention, pressure is applied between the image carrier and the image transferring means. Toner is provided with relatively high hardness in accordance with the pressure beforehand. Image transfer is effected by reducing a potential difference between the image carrier and the recording medium while maintaining an electric field around the toner the same.

In a speaker, a magnet 23 is disposed at a mid position of a voice coil bobbin 25 mounted on a cone 34. A couple of voice coils 28 and 29 are put around the circumferential outer surface of the voice coil bobbin 25 at the positions thereof facing one end and the other end of the magnet 23. A magnet 32 is disposed within the voice coil bobbin 25, and develops two magnetic fields in a state that the first and second voice coils 28 and 29 are located between the one and other ends of the first magnet 23. Dampers 26 and 27 support the voice coil bobbin 25 at positions such that the voice coil bobbin 25 is axially vibratory. Those positions are located on both sides of and symmetrical with respect to those portions of the voice coil bobbin 25 which are respectively wound with the voice coils 28 and 29.
摘要:
An image forming apparatus of the present invention includes a latent image forming device for forming a latent image on an image carrier and a developing device for developing the latent image with toner to thereby form a corresponding toner image. The surface of an intermediate image transfer body is movable and includes an high-resistance layer having a volume resistivity of 1010 &OHgr;·cm or above. A primary image transferring device transfers the toner image from the image carrier to the intermediate image transfer body. Secondary image transferring device transfers the toner image from the intermediate image transfer body to a sheet. A polarization uniforming device uniforms, at the beginning of an image forming operation, polarization left in the high-resistance layer while preserving the polarity of the polarization after the surface of the intermediate image transfer body has started moving, but before the toner image is transferred from the image carrier to the secondary image transfer body.
