Abstract: A method of properly aligning a sliding side door on a vehicle includes first preparing a prototype vehicle and determining how far out of alignment the door is to the body of the prototype vehicle. This amount of misalignment is then used to adjust the attachment position of an anchor plate to a sliding side door of the vehicle, so that the anchor plate is attached at a desired position to the production vehicle, which causes there to be no misalignment between the sliding side door and the body of the production vehicle. A jig is used to hold the anchor plate at the desired location while welding the anchor plate to the door. A roller assembly is then attached to the anchor plate and to a rail on a body of the vehicle.

Abstract: An analyzing device having a microchannel structure includes a sample inlet and a guide section extending from the sample inlet toward an axial center. The analyzing device further includes a first cavity connected to the guide section and configured to measure a certain amount of a sample liquid, and a receiving cavity located adjacent to the first cavity and receiving the sample liquid. The analyzing device further includes a liquid reservoir formed between the sample inlet and the guide section and temporarily holds the sample liquid before being suctioned into the guide section. The sample liquid temporarily held in the liquid reservoir is transferred from the liquid reservoir to the guide section and the first cavity by a capillary force and transferred to the receiving cavity by a centrifugal force caused by rotating the analyzing device about the axial center.

Abstract: A flash discharge tube includes tungsten pins configuring a pair of discharge electrodes, and an envelope. The envelope includes a central region, serving as an alkali-free region, which is configured with an alkali-free glass except for quartz glass. The central region becomes in a high temperature state during a firing operation of the flash discharge tube. The central region is smaller than a maximum region enclosing a gas-tight space formed by hermetically sealing the pair of the discharge electrodes and is not smaller than a minimum region enclosing an arc-discharge space formed between the tungsten pins of the pair of the discharge electrodes. The alkali-free region contains either no alkali metal component or not larger than a predetermined amount of an alkali metal component. Then, a trigger electrode is disposed in the alkali-free region. This provides the flash discharge tube featuring a stable short-interval continuous-firing operation.

A sample liquid collected from a leading end of the inlet 13 is transferred to a separation cavity 23. A bent section 22 and a recess 21 are formed at a connected section of the guide section 17 and the capillary cavity 19 so as to change the direction of a passage.

Abstract: An analyzing device includes: an operation cavity (245) that is adjacent to a first reserving cavity (243) retaining a sample liquid, in a circumferential direction of rotational driving; a connecting section (255) provided on a side wall of the first reserving cavity (243) to suck the sample liquid by a capillary force and transfer the sample liquid to the operation cavity (245); and second reserving cavities (247, 248) that are disposed outside the operation cavity (245) in the circumferential direction of the rotational driving and communicate with the outermost position of the operation cavity (245) through a connecting passage (256). The connecting section (255) is circumferentially extended farther than the liquid level of the sample liquid retained in the first reserving cavity (243). Thus it is possible to reduce the quantity of the sample liquid, eliminate irregular agitation of a sample liquid and reagents, and reduce the size of an analyzing device.

Abstract: An analyzing device mixes a sample liquid with a reagent by rotation of the analyzing device about a rotation center to generate a centrifugal force. A measurement cell is formed so as to extend in a direction along which the centrifugal force is applied, and a capillary area to which the sample liquid is sucked by a capillary force is formed on one of the side walls of the measurement cell, the side walls being arranged in a rotational direction. The capillary area extends from the outer periphery position to the inner periphery of the measurement cell, thereby reducing the size of the analyzing device. Further, the sample liquid in the measurement cell is sucked to the capillary area by slowing or stopping a rotation, and then the rotation is accelerated to return the sample liquid in the capillary area to the measurement cell.

Abstract: An analysis device includes a separation chamber, a holding channel, a mixing chamber connected to the holding channel, an overflow channel connected between the holding channel and the separation chamber, a sample overflow chamber into which a sample solution remaining in the separation chamber is discharged, and a joint channel connecting the separation chamber and the sample overflow chamber. After the separated solution component fills the overflow channel with priority, a separated solid component is transferred to the holding channel via the overflow channel, and a predetermined amount of the solid component is measured. The solid component in the holding channel is transferred to the mixing chamber by a centrifugal force, and simultaneously, the sample solution remaining in the separation chamber is discharged to the sample overflow chamber by the siphon effect of the joint channel.

Abstract: A protective cap 2 is engaged with a latch 10 of a diluent container 5 so as to fix the diluent container 5 at a liquid holding position of a diluent container containing section 11. The engagement is released when the protective cap 2 is set to an open position against the engagement so as to expose an inlet 13. When the protective cap 2 is shifted from the open position to a closed position, the protective cap 2 pushes the diluent container 5 into a liquid discharge position. Thus, it is possible to preserve a diluent for a long period of time and to easily open the diluent container 5 without having to complicate the structure of an analysis apparatus.
