Abstract:
A liquid injecting jig is provided. The liquid injecting jig includes a jig configuration including a plurality of parts adapted to be in cooperative engagement so as to position a channel within the jig configuration, wherein the jig configuration is adapted to fit an opening through which the channel is adapted to be received so as to expose the channel from the jig configuration. A jig set, a microchip case, and a microchip set are also provided.
Abstract:
An optical head enabling a size reduction so that the optical head can be stored in an opening of a cartridge for a disk and enabling an improvement in the dynamic performance as the density and transfer rate are increased is provided. In a two-axis actuator optical head capable of driving an objective lens (102) along the Z axis in the focus direction, that is, vertical to the surface of the optical disk and along the X axis in the tracking direction, that is, the radial direction of the optical disk. The objective lens (102) is disposed in the center of the coil bobbin (101), a focusing coil (103) is disposed around the coil bobbin (101) and is wound around the X axis, and tracking coils (104a and 104b) are disposed on both ends of the coil bobbin (101) in the X axis direction and are wound around the X axis. Pairs of magnets (107a to 107d) are disposed plane-symmetrically with the Z-Y plane including the Z axis aligned with the optical axis of the objective lens (102) and the Y axis and with the Z-X plane including the Z axis and the X axis.
Abstract:
Provided is a microchip which enables to easily confirm, from the outside of the microchip, filling of a solution into an analysis region. The microchip includes: an introduction part for introducing a liquid; an analysis region in which a substance contained in the liquid or a reaction product of the substance is analyzed; an indication region to indicate that the analysis region has completely been filled with the liquid; and a flow channel to connect the introduction part, the analysis region, and the indication region. In the microchip, the flow channel is configured in such a manner that an amount of time it takes for the liquid introduced from the introduction part to reach the indication region is longer than an amount of time it takes for the liquid introduced from the introduction part to fill up the analysis region.
Abstract:
There is provided a nucleic acid analysis apparatus including a heating unit configured to apply heat by contacting a microchip, and a chip holding unit configured to change a position between a first holding position that holds the microchip in midair and a second holding position that holds the microchip in contact with the heating unit.
Abstract:
An optical pickup incorporates a two-lens system with first and second lenses (13) and (14) being arranged in the following manner: the first lens has a first surface (15) to receive a laser beam radiated from a semiconductor laser and a second surface (16) to direct the laser beam transmitted from the first surface (15) towards the second lens (14); the second lens (14) has a third surface (17) to receive the light flux transmitted from the second surface (16) and a fourth surface (18) to direct the light flux transmitted from the third surface (17) towards an optical disc placed opposite thereto; and the first and fourth surfaces (15, 18) are used as a reference during positioning. The aberrations of the optical pickup are limited within a tolerable limit without incorporating a special device for that purpose even if errors arise in thickness of component lenses of a two-lens system constituting an element of the pickup.
Abstract:
An objective lens having a doublet structure and a numerical aperture of 0.7 or more and an optical pickup apparatus having this objective lens are adapted to an optical recording medium having a high information recording density, the objective lens being structured such that at least one side is formed into a aspheric surface and the lens elements (3, 4) are made of low-diffusion glass having an Abbe's number of 40 or greater.
Abstract:
The disc drive device is adapted for holding plural discs of different sizes in stable state such as to provide a sufficient recording area for each disc. In addition, the disc drive device is adapted for setting the discs of different sizes accommodated in cartridges of different thicknesses at a predetermined height in order to run the disc in the cartridge in stability. With the disc drive device, turntables (31, 32) for rotatably holding the discs vary the holding areas for the discs depending on the disc size.
