受験番号：16IPM019[0002] Some small electronic devices of a known art, such as a camera-integrated video
tape recorder and a transceiver, use batteries as a power source, including a primary
battery and a secondary battery. These batteries are so readily accessible to a user thatthe usability can be improved. However, general users have little understanding that theoperating time of the batteries is strongly affected by temperature. Therefore, there has
been a problem that the user anxiously question failure when the operating time isextremely shortened when using a small electronic device with the battery under lowtemperature environments such as in a ski area and in a snow mountain.
[0003] In practice, for example, the operating time under an environment of a lowtemperature of 0 degree C or less can be reduced half or shorter as compared with theoperating time under an environment of an ambient temperature of about 20 degrees C.
Incidentally the battery duration of a AA alkaline dry cell under environments atemperature of 25 degrees C is reduced to about half or a quarter as compared with thesame under a temperature of 10 degrees C.
[0004] In order to overcome the above-mentioned problem, there has been proposed abattery provided, on the surface of a packing member for distribution thereof, with atemperature characteristic indication means made of a temperature sensitive material
which changes in color with temperature.
Further, the surface of the battery is provided with a temperature characteristic
indication means made of a temperature sensitive material which changes in color withtemperature.
In this way, the temperature at which the battery is used can be recognized from color
changes of the temperature characteristic indication means, indicating an available
operating time based on the temperature so that the usability can be improved.

[0030] Fig. 1 is a perspective view of an intermediate member 120 which is fixedly
secured to a collimator lens. The intermediate member 120 according to the first
embodiment is provided with recesses 121a and 121b which are formed respectively on
the top and back surfaces and correspond to the collimator lens as seating faces for
fixing the collimator lens. Further, the intermediate member 120 is provided with throughholes 124 for inserting screws, near both ends thereof in a main scanning direction. In themeantime, one through-hole 124 is formed symmetrically with respect to the otherthrough-hole 124 with reference to a line of an optical axis direction extending through acentral portion of the intermediate member 120A in a main scanning direction. The
through-holes 124 formed in the above manner enable that when an optical scanningdevice is reused, the mounting position of the intermediate member 120 with respect tothe housing can be changed by 180 degrees from the previous mounting position about
the optical axis. Thus, the recess 121b on the back surface of the intermediate member
120 which is not applied with an adhesive can be used as new seating surface for fixing
the collimator lens.
[0031] Preferably, the surfaces of the recesses 121a and 121b are so roughened that the1surface areas thereof are greater than that of the outer peripheral surface of thecollimator lens. In this way, the greater surface areas of the recesses 121a and 121benable an adhesive to stay in the recesses 121a and 121b, preventing the adhesive fromattaching to the collimator lens.

What is claimed is:1.
A folding umbrella link mechanism for use in an umbrella framework structure,comprising:an umbrella shaft 1 having a ferrule at one end and a handle on the other end;
a fixed wheel 5 fixed to an end of the umbrella shaft 1 in a direction in which theferrule is disposed;
an umbrella rim fixed to the fixed wheel 5 in a radial fashion;a movable wheel 2 movable in an axial direction of the umbrella shaft 1; anda receiving rib 3 for coupling the movable wheel 2 to the umbrella rim,wherein
the umbrella rim includes a plurality of coupling ribs 6, each coupling rib 6 being
pivotably fixed at one end thereof to a peripheral portion of the fixed wheel 5, a pluralityof drive rods 7, each drive rod 7 being pivotably fixed at one end thereof to the other endof the coupling rim 6 opposite to the fixed wheel 5, anda plurality of main ribs 4, each intermediate part of the main ribs 4 in an axial direction
being pivotably fixed to an end of the drive rod 7 opposite to the coupling rib 6, andthe receiving rim 3, at one end thereof, is pivotably fixed to a peripheral part ofthe movable wheel 2 and, at the other end thereof, is pivotably fixed to an end of the mainrib 4 on the fixed wheel 5 side, and is supported at an intersection point with the couplingrib 6.
