Title: Diamond coated cutting tool and its manufacture
Inventor: AIDA HIROSHI
IPC: B23B27/14
Filed: 1985-04-30
Abstract: PURPOSE:To manufacture a cutting tool of non-peeling off, high cutting performance by forming diamond film on a base body having toughness (Kic) of 6 or more than 6 through a vapor growing method and polishing it. CONSTITUTION:A diamond film is formed on a base body having toughness (Kic) of 6 or more than 6 through a vapor growing method such as CVD method and the like. Then, at least the surface of the diamond film including cutting edges is polished to less than 1mum in surface roundness and 10mum or more than 10mum in film thickness, thus, the cutting tool is obtained. Sintered Si3N4 is especially suited for the base body of the tool considering adhesiveness. In case that toughness is smaller than 6, chipping takes place from edge portion of the tool while being cut or handled and that may possibly induce peeling off, accordingly, the toughness is selected to be 6 or more than 6.

Title: Zero-loss wave director coupler
Inventor: DEIBITSUTO FUINKU
IPC: G02B6/32
Filed: 1993-04-21
Abstract: PURPOSE: To make reflected and returned beams have the same laser mode field distribution as an output beam in a coupler which reflects a laser beam and returns it to a laser waveguide with a reflecting mirror, and eliminate clipping loss and coupling loss. CONSTITUTION: In a waveguide 10, a surface terminal reflecting mirror 16 forms, by reflection, an image of the outlet plane of a waveguide laser 10, with essentially accurate regeneration and phase distribution of the waveguide output intensity. A lens 18 is arranged in the vicinity of a waveguide outlet 12 between an outlet hole and the reflecting mirror. In order that the phase of a beam returned to the waveguide 10 may match the phase of an outgoing beam, the lens 18 performs phase compensation to the beam which passes the lens. Thereby the coupling loss due to the clipping of a return beam and the coupling loss due to the mismatching of return field phase with waveguide mode phase are made zero. A waveguide laser can also be coupled with another waveguide laser, having a similar size hole or a different size hole, without reflection.

Title: Thermal recording body
Inventor: KOSHIZUKA KUNIHIRO
IPC: B41M5/40
Filed: 1990-04-10
Abstract: PURPOSE:To prevent a blocking phenomenon by a method wherein a heat- softening coloring material layer for forming an image is provided on a recording substrate, and a back coat layer is provided on the opposite side thereof. CONSTITUTION:On the surface of a recording substrate on the opposite side of a heat-softening coloring material layer, a back coat layer is formed. As the components of the back coat layer, components of the heat-softening coloring material layer other than the coloring material, i.e. a binder and the like, can be used, but a water-soluble resin or an aqueous emulsion resin is preferable. When the back coat layer is formed on the rear of the recording substrate in this manner, the substrate is not brought into direct contact with the heat- softening coloring material layer, a releasable substrate layer, or the like but the back coat layer even in the storage of a photosensitive recording body wound in a roll form. An adhesion of the back coat layer with the heat-softening coloring material layer or the releasable substrate layer is remarkably smaller than that of the recording substrate with the heat-softening coloring material layer. Therefore, this recording body can be smoothly rewound for use from the roll-form wound state.
