摘要:
A biaxially oriented laminated polyester film comprising:(A) a first thin polyester layer formed from an aromatic polyester containing two kinds of inert fine particles having different size and(B) a second polyester layer formed from an aromatic polyester, on at least one surface of which the above first thin polyester layer is present. This biaxially oriented laminated polyester film is is excellent in lubricity, abrasion resistance and scratch resistance and is particularly useful as a base film for a magnetic recording medium. The two kinds of inert fine particles include inorganic fine particles having an average particle diameter, d.sub.a of 0.02 to 0.3 .mu.m and organic fine particles having an average particle diameter, d.sub.b of 0.2 to 1.5 .mu.m, and d.sub.b >d.sub.a.

Provided are a device, a system, and a method for determining a fitting condition of a connector, which are capable of improving the accuracy for determining the coupling condition of the connector. A connector fitting condition determination device (10) includes an input section (11) that is attached to an operator and receives detection results including sound information and acceleration information that are measured at a time of fitting a connector; a sound information determination section (13) that determines whether the sound information satisfies predetermined conditions based on the detection results input to the input section (11); and an acceleration information determination section (15) that determines whether the acceleration information satisfies predetermined conditions, on detection results satisfying the conditions in the sound information determination section 13. The determination device (10) determines that the connector is fitted, only when both the sound information and the acceleration information satisfy the predetermined conditions.
摘要:
A humidity indicator including a coloration composition, which contains a deliquescent material, supported on a porous base material, wherein the adhesion of the coloration composition, which has been once printed and thus adhered to the base material, to a member or the like of a printer is inhibited in a production process to thereby reduce printing errors and the maintenance frequency of the printer. Furthermore, blocking which occurs in stacking multiple humidity indicators can be prevented. Beads not reacting with the constituting components of the coloration composition are dispersed into the coloration composition to form convex portions. Further, the coloration composition is coated with a top coat layer including beads dispersed in a resin.

A packaging bag and a drying agent with a moisture absorption indicator function are provided without using a heavy metal harmful to the human body. The packaging bag includes a first packaging material (10) and a second packaging material (20). The first packaging material (10) is provided on an outermost side thereof with a transparent barrier film (12) having a barrier property against water vapor. The second packaging material (20) has a light-reflective or light-absorbing film (24) and a pattern printed layer (23) overlaid on a bag interior side thereof, the pattern printed layer (23) having a printed moisture-absorbing indicator pattern (30). A desiccant-containing resin film (11, 21) which becomes transparent due to moisture absorption is overlaid on a bag interior side of at least one of the first packaging material (10) and the second packaging material (20). The drying agent with a moisture absorption indicator function includes an indicator film layer (70) having a barrier film (75), a pattern printed layer (73) for a moisture absorption indicator, and a moisture-absorbing film (71) containing zeolite, the pattern printed layer (73) and moisture-absorbing film (71) being laminated in this order on the barrier film (75). The drying agent further includes a main desiccant layer (61) and a moisture permeable film (64) that are overlaid on the moisture-absorbing film (71).
摘要:
The invention provides an electrode device that prevents disconnection of an electrode layer effectively by reducing stress at the time when a recess is formed.An electrode device (10) has a protrusion (70), which projects upward, in the part of an outward flange section (110f), other than a recess (60) formed by molding. The protrusion (70) is arranged so as to surround an outer periphery of the recess (60). When the recess (60) is cold-pressed, the protrusion (70) prevents warp (warp waving along a peripheral direction) in the outward flange section (110f) from occurring. Consequently, the protrusion (70) also eases warp of an electrode layer (30) extending on the outward flange section (110f) and prevents disconnection of the electrode layer (30).
