Title: Lens usable for short-distance photographing
Inventor: MORIYAMA KEIJI
IPC: G02B15/163
Filed: 1988-07-08
Abstract: PURPOSE:To obtain excellent image forming performances over a photographing range from infinite photographing to shortest-distance photographing by expanding the interval between the 2nd and 3rd lens groups while the interval between the 1st and 2nd lens group is reduced when focusing operations are performed in a range from infinity to the shortest distance. CONSTITUTION:When focusing operations are made in a range from infinity to the shortest distance, the interval between the 2nd and 3rd lens groups G2 and G3 is expanded while the interval between the 1st and 2nd lens groups G1 and G2 is reduced so that the conditions of Inequality I can be satisfied. The DELTAs1 and DELTAs2 of the inequality respectively represent the moving quantity of the 1st lens group G1 from the infinite photographing state to an arbitrary object photographing state and the moving quantity of the 2nd lens group G2 from the infinite state to an arbitrary object photographing state. Therefore, a high-performance lens which does not change much in total length while the lens holds excellent image forming performances even when the lens is used for photographing objects in a range from infinity to the shortest distance and is high in operability can be obtained.

Title: Reversible thermal recording sheet
Inventor: TAKEMOTO SHINYA
IPC: B41M5/26
Filed: 1993-07-09
Abstract: PURPOSE:To impart good repeated durability even to a recording printing and erasing means high in pressure/shearing force such as a thermal head in a reversible thermal recording sheet having a recording layer generating a reversible change between transparent and opaque states by temp. CONSTITUTION:In a reversible thermal recording sheet wherein a recording layer 2 generating a reversible change between transparent and opaque states by temp. is provided on a base material 1, a flexible rubber elastic layer 4 absorbing pressure/shearing force at the time of recording printing/erasure is provided under the recording layer 2. Therefore, since the elastic layer under the recording layer absorbs pressure/shearing force at the time of recording printing/erasure, the collapse of the recording layer can be reduced. As a result, even when the load of the pressure/shearing force to the reversible thermal recording sheet due to an increase in printing/erasing speed or the compaction of an apparatus is increased, the lowering of repeated durability can be reduced.

Filed: 1987-07-07
Abstract: PURPOSE:To ensure gas diffusion without relying on water repellency of polytetrafluoroethylene and to increase the utilization of a catalyst by arranging specific fibrous activated carbon in an electrode substrate. CONSTITUTION:Porous fibrous activated carbon 13 having 0.1mum craterlike pores 14 is arranged in a fuel electrode substrate 6 and an air electrode substrate 7. Noble metals 10 which form a catalyst by penetration adsorption, and reduction treatment are supported within each of the pores 14. The noble metals are densely supported without forming a catalyst layer. By the constitution using no polytetrafluoroethylene, large spaces surrounded by fibers 13 are formed in the substrates 6, 7, and they form sufficient gas diffusion passages without filled by phosphoric acid in a normal operating condition. Phosphoric acid penetrates into the pores 14 by capillary phenomenon, and reaction gas dissolved in the phosphoric acid reacts on the noble metals 10. Since the noble metals 10 are not covered with polytetrafluoroethylene, the utilization of the catalyst is increased.
