摘要： The invention provides transmission which satisfies specifications for SD-format digital interface in a transmission device with an isochronous transmission mode, such as those of IEEE 1394 for digital data transmission/reception. The device for converting data transfer rate in communication of digital audio/video data comprises a timing simulator and a transmission timing controller. The timing simulator receives some signals and mode signals to indicate occurrence of transmission basis signals for transmitting the stream of the source packets and outputs the transmission basis signals. The transmission timing controller receives the transmission basis signals and transmits packets at every cycle sync, according to fixed rules. The device for converting data transfer rate in communication of digital audio/video data can overcome the different data transfer rates of the inner bus of the digital device (camcorder) and IEEE 1394, and thereby satisfy the specifications for SD-format digital interface.

摘要： A pickup actuator having a base member (10) as a fixed member, a lens holder (20) as a travelling member, wherein a damping fluid (50) is applied therebetween. The damping fluid (50) damps a vibration occurring at the lens holder when the lens holder (20) is driven. Here, the damping fluid (50) has a viscosity ranging from 1000cP to 2000cP at 27°C, in which magnetic particulates are stably dispersed. It is preferable that the damping fluid is magnetized to 100G ∼ 200G in a magnetic field of 3∼4k0e. When there occurs vibration at the lens holder (20) by any reasons, such vibration is directly damped by the damping fluid (50) applied between the base member (10) and the lens holder (20). Thus, an objective lens (22) can reach its designated spot more rapidly. Further, since there is no need for an injection of damping bond into an inner space of holder supporting portion, the manufacture becomes simpler, and manufacture costs thereof are accordingly reduced.

摘要： An apparatus for indicating information concerning the level of a liquid (41) contained in a tank (42) includes a tank (42), at least one exhaust pipe (51-53) having a transparent portion (51c-53c), a light source (51-63) for emitting light to the transparent portion (51c-53c) of each of the exhaust pipes (51-53), a photodetector (71-73) for detecting light reflected by or transmitted through the transparent portion (51c-53c) of each of the exhaust pipes (51-53) and outputting electric signals corresponding to the detected light, and a liquid level measuring portion (80) for indicating information concerning the level of liquid (41) contained in the tank (42) from the electric signals output from the photodetector (71-73). The transparent portion (51c-53c) of the exhaust pipe (51-53) is formed at least as a part thereof, the exhaust pipe (51-53) having a first end (51a-51c) thereof installed to be connected to the tank (42) and a second end (51c-53c), horizontally displaced from the first end (51a-53a) and connected to a set supply path (54) and/or the tank (42) so that liquid (41) can be collected. The exhaust pipe (51-53) is installed at a predetermined height vertically from a bottom surface (42a) of the tank (42) to obtain information on the level of liquid (41) contained in the tank (42). Thus, developer can be prevented from adhering to the transparent portion (51c-53c) of the exhaust pipe (51-53) installed at the tank (42) at a height to be indicated so that an error in measuring the level of liquid (42) can be reduced.

摘要： A sheet coating apparatus including a storage tank (100) in which a coating liquid (W') having charged coating particles dispersed therein is contained, a development roller (110) rotatably installed to be immersed in the coating liquid, a voltage source (111) for applying a voltage to the development roller (110), a coating roller (120) rotatably installed in a state in which it is partially immersed in the coating liquid while maintaining a predetermined development gap relative to the development roller (110), and a compression roller (150) for pressing a sheet (1) passing between the same and the coating roller (120) toward the coating roller (120) while securely rotating with respect to the coating roller (120), wherein the coating particles adhere to the surface of the coating roller (120) at the development gap due to an electric force to then be coated on the sheet passing between the coating roller (120) and the compression roller (150). The sheet coating apparatus can prevent excess coating liquid from being coated on a sheet by regulating the amount of the coating liquid coated on the sheet, thereby attaining uniform coating.

摘要： There is provided an apparatus for driving a squeegee roller (230) for a liquid electrophotographic printer including a squeegee gear (240) coaxially installed at one shaft end of the squeegee roller (230), a driving gear (250) installed such that in a state where the squeegee roller (230) contacts the photoreceptor belt (10), the centre of the rotation shaft thereof is positioned on a plane perpendicular to the elevating direction of the squeegee roller (230) and passing through the centre of the rotation shaft of the squeegee roller (230), to be engaged with the squeegee roller (230), and a driving source (M) having an output shaft for rotating the driving gear (250) to drive the squeegee roller (230) to rotate in a reverse direction to the rotating direction of the photoreceptor belt (10). Therefore, even when a drip line removal mode of the printer is terminated to be switched to a stop mode, the squeegee roller (230) does not stop but keeps rotating in reverse while it is in the course of being lowered from the photoreceptor belt (10), thereby removing a drip line on the photoreceptor belt (10) as accurately as possible.

摘要： A squeeze roller elevating apparatus of a liquid electrophotographic printer for selectively pressing a photoreceptor belt (100) installed at a belt frame (300) to be capable of circulating by elevating a squeeze roller (110), includes a housing (500) fixed at the belt frame (300), a squeeze frame (200) installed inside the housing (500) to be capable of elevating for supporting the squeeze roller (110), a first elevating member (210) installed at the squeeze frame (200) to be capable of elevating, a second elevating member (210) installed at the squeeze frame (200) to be capable of elevating by being interlocked with an elevating movement of the first elevating member (210) and moving the squeeze frame (200) upward so that the squeeze roller (110) presses the photoreceptor belt (100) while ascending, a first spring (230) coupling the first elevating member (210) and the second elevating member (220) to be interlocked with one another, a second spring (240) coupling the second elevating member (220) and the squeeze frame (200) to be interlocked with one another, and means for elevating the first elevating member (210). Thus, since the print mode, the "drip-line" mode, and the standby mode are performed as the squeeze roller (110) installed at the squeeze frame (200) is elevated, a repulsive force generated when the photoreceptor belt (100) is pressed can be prevented from being transferred to the main frame (300).

摘要： A high-density focusing objective lens having a high numerical aperture (NA), which can be easily manufactured by an existing technique, and an optical pickup adopting the objective lens for use in high-density recording. The objective lens (155) includes: a first transmitting portion (156) placed at a relatively near-axis region from the optical axis, for divergently transmitting an incident beam; a first reflecting portion (157) for divergently reflecting the incident beam, facing the first transmitting portion (156); a second reflecting portion (158) formed at a relatively far-axis region around the first transmitting portion (156), for focusing and reflecting the light reflected from the first reflecting portion (157); and a second transmitting portion (159) formed at a relatively far-axis region around the first reflecting portion (157), for refracting and transmitting the light focused by the second reflecting portion (158), wherein the maximum angle α between the optical axis and the peripheral beam passing through the second transmitting portion (159) after having passed through the first transmitting portion (156) and been reflected by the first and second reflecting portions (157;158) satisfies the condition of 30° ≤ α ≤ 65°. The optical pickup further includes the previously mentioned objective lens (155) as a second objective lens, which is optionally placed into the optical path between a first objective lens and an optical medium. As a result, the NA of the objective lens unit can be increased up to 0.85 while the working distance d 2 is maintained to be 2 mm.
