Parking devices that lock bicycles are installed in bicycle parking lots.

One example of conventional technology is a parking device that locks a bicycle byopening/closing arms engaging somewhat above a position where a wheel is incontact with the ground.

When locking the bicycle, the locking arms that are in aclosed state by a spring member are pushed open by the front wheel, and then are
returned to the closed state by the spring member upon the front wheel striking anabutting plate that activates a switch. Another example of conventional
technology is a parking device having a portion that is depressed by the front wheel
when the front wheel is at a parking position, and opening/closing arms linked
thereto close to cradle the front wheel.
[0003]

However, the opening/closing arms are attached to the parking device

with a considerable amount of looseness or play, as a precaution, so as to be able tohandle a range of wheel sizes and thicknesses of bicycles without damaging
someone's bicycle.

Accordingly, the bicycle may not be able to be locked if the front

wheel is tilted or not at the correct position.
【問 2】
As described above, there is provided a spray generating method by a fluid
injection valve. The fluid injection valve includes the valve seat 10 that has thevalve seat face 10a partway along the fluid channel, the value body 8 that controls
opening/closing of the fluid channel by separation from and contact with the valve
seat face 10a, and the nozzle hole plate 11 that has a plurality of nozzle holes 12 andis situated downstream from the valve seat 10. Flows in the nozzle holes and flows
directly below the nozzle holes of the fluid injection valve form a general liquid film
flow. The directions of the jet flows 30 and 31 from the nozzle holes 12 neither arenecessarily aligned with the center axial direction of the nozzle holes 12, nornecessarily intersect each other downstream.

After becoming sprays at adownstream position, the jet flows from the nozzle holes 12 are brought into
proximity or converged by the Coanda effect that acts among the plurality of sprays.
Once the sprays are identifiable as having substantially become a solid cone,entrainment of ambient air primarily based on momentum theory, and resultant
induction of airflow following the downstream flow at a predetermined portion

within the sprays, are generated.

Peaking of the injection quantity distribution at

the generally center portion thereof and reduction in the spray angle are continued
until these behaviors substantially disappear.

Thus, both atomization of fuelsprays, and improved freedom of design regarding spray form, spray pattern, andinjection quantity distribution, can be achieved.

It should be clearly understoodthat the peak of the injection quantity distribution does not necessarily have to be
the general center portion of the spray cross-section, and that the spray angle does
not necessarily have to be minimal.

It should further be clearly understood thatthe same advantages can be obtained by a nozzle part where the nozzle hole plate 11
and the valve seat 10 are integrally configured.

1.

A refill (2) for a ballpoint pen (1), comprising:a first annular component (3) having a rearward end (50) and an outer

peripheral surface (5) on the rearward end (50);a second annular component (4) made of an elastic material, the second
annular component (4) having an inner circumferential surface (6), the inner
circumferential surface (6) fitting onto the outer peripheral surface (5); andan ink (7) housed in a space partitioned by the first annular component (3)and the inner circumferential surface (6), wherein
the outer peripheral surface (5) includes: a first inclined portion (51) that
increases in outer diameter with increasing separation from the rearward end; afirst annular portion (52) continuous with the first inclined portion (51); a second
inclined portion (53) continuous with the first annular portion (52), the second
inclined portion (53) decreasing in outer diameter with increasing separation fromthe rearward end; an annular recessed portion (54) continuous with the second
inclined portion (53); a third inclined portion (55) continuous with the annular
recessed portion (54), the third inclined portion (55) increasing in outer diameterwith increasing separation from the rearward end; and a second annular portion(56) continuous with the third inclined portion (55), the second annular portion (56)having a constant outer diameter,
the inner circumferential surface (6) has an inner diameter smaller thanthe outer diameter of the second annular portion (56) and larger than an outer
diameter of the annular recessed portion (54) before the fitting; andthe first annular portion (52) has an outer diameter larger than the outer
diameter of the second annular portion (56).
