Title: Optical recording medium
Inventor: HARIGAI MASATO
IPC: G11B7/24035
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To improve an S/N and a jitter characteristic and to cope with a DVD-R and a blue laser or the like by executing recording by utilizing a phenomenon wherein density of an element composing a first recording layer is inverted with density of an element composing a second recording layer owing to irradiation by laser beams. SOLUTION: An element of material of a first recording layer is expressed with A and an element of material of a second recording layer thereon is expressed with B. When both layers are not irradiated with recording laser beams, density of a base side element A is major and density of the element B being a second layer thereon is major. When a film thickness of the first recording layer and the same of the second recording layer are respectively limited to the range of 100-250 Å and 50-200 Å and both layers are irradiated with the laser beams, mutual diffusion rapidly progresses, density distribution is inverted, the upper layer is replaced by the lower layer in appearance, density of the base side element B becomes minor and density of the element A thereon becomes major, and recording becomes possible.  When a valence of a recording material of the first and second recording layers is respectively expressed with X and Y, activation energy of the element is reduced by using an element of 1<=X-Y<=3.

Title: Transmission for working machine
Inventor: NAKADA MASAYOSHI
IPC: F16H61/28
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To perform a multistage transmission while keeping the axial center directional width of a transmission within a practicable width by selectively ON-operating a multiple disc clutch interposed in each of a plurality of transmission routes having mutually different transmission ratios by pressure oil feed. SOLUTION: A disc clearance δ1 between the high-speed clutch c2 of a first transmission 18 and the forward first clutch C1 of a second transmission 19 is set smaller than the disc clearance δ2 of the other hydraulic clutch C (c1, c2, c3, c4) to prevent the oil quantity required for ON-operating both the clutches from increasing, and the time required for ON-operating the hydraulic clutches is shortened, whereby the reduction in traveling speed accompanying the shift can be suppressed. The number of speeds as the whole is set so as to be the product of the number of shift stages of each transmission, whereby the number of shift stages of the individual transmission can be minimized while performing a multistage shift, and the axial center directional width of the individual transmission can be minimized.

Abstract: PROBLEM TO BE SOLVED: To enable swimming even during nighttime and activate water to suppress water contamination by providing a tile main body having the magnetic effect and light storage property on a bottom face and a side face of a swimming pool. SOLUTION: A tile main body 1 is formed by baking finishing a base main body 5 formed by spraying light storage agent 3 and nonleaded flux 4 on a surface of a base 2 formed by earthenware stone as a raw material.
