| 20100061684 | OPTICAL COMMUNICATION MODULE, MANUFACTURING METHOD THEREFOR, AND OPTICAL TRANSCEIVER - A manufacturing method of an optical communication module for manufacturing the optical communication module, including the sequentially performed steps of: (1) mounting a light-emitting element and a light-receiving element on a side surface of a sub-mount substrate and mounting the sub-mount substrate on a printed circuit board such that the light-emitting and -receiving directions of the light-emitting element and light-receiving element are parallel to the printed circuit board; (2) aligning an optical waveguide; and (3) dropping resin solution on an area of the sub-mount substrate including an optical waveguide end and the light-emitting element or the light-receiving element, and curing the resin solution. According to the present invention, it is possible to provide an optical communication module which can be made thin, small and cheap. | 03-11-2010 |
| 20110058819 | OPTICAL TRANSMISSION DEVICE - Provided is an optical transmission device which includes: an optical transmission unit including a light-emitting element; an optical reception unit including a static current source generating bias current for driving the light-emitting element; a light-transmitting medium optically connecting the light-emitting element and a light-receiving element to each other; and an electricity-transmitting medium transmitting the bias current from the static current source to the light-emitting element. | 03-10-2011 |

| 20100239378 | END MILL - An end mill having a gash formed in a top portion of a flute. In a cross-section perpendicular to an intersecting ridgeline between an end cutting edge rake face and a gash bottom face of the gash, the gash bottom face and the end cutting edge rake face, and the gash bottom face and the gash wall face are respectively connected together by first and second connecting faces. The connecting faces have a form which either is a concave curve or a substantially concave curve formed with straight lines. A radius of curvature of the concave curve or the radius of a circle inscribed within straight lines forming the substantially concave curve about the front connecting face is larger than a radius of curvature of the concave curve or the radius of a circle inscribed within the straight lines forming the substantially concave curve about the second connecting face. | 09-23-2010 |
| 20100247263 | Exchangeable cutting head and cutting tool having the same - An exchangeable cutting head that is inserted into a mounting hole formed on a tool body, screwed on a mounting screw section provided on a bottom portion of the mounting hole, and is attached removably to the tool body, the exchangeable cutting head includes: a cutting head body including: a cutting portion provided at a front-end section; a mounting portion provided at a rear-end section and inserted into the mounting hole; and an engaging hole having an inner-peripheral face on which a recessed portion is formed, the cutting head body being made of a hard material; and a connection member including: a shaft portion that is inserted into the engaging hole, includes an outer periphery attached firmly to the inner-peripheral face of the engaging hole, and is engaged with the inner-peripheral face; a head screw section screwed with the mounting screw section; and a hole section formed inside of the head screw section and the shaft portion and along a center line of the shaft portion, the connection member being made of a metal material having a degree of hardness lower than a degree of hardness of the hard material and the connection member being connected to the cutting head body. | 09-30-2010 |

| 20110234355 | COIL TRANSFORMER COMPOSED OF UNIT CONFIGURATION - There are many varieties of windings. Coils adopting an edgewise winding wire in which winding wires are wound around in the radial direction of the coil have a wide flux linkage area orthogonal to the electric wire, so that stray loss within the wire is increased, winding wire loss is increased and temperature is raised thereby. The present invention provides an arrangement in which a plurality of coil units are prepared and connected via external coupling terminals. At this time, winding is performed so that the contact faces of the coil units have equal potentials, so that there is no need to ensure an insulation distance between coils, and the coils can be downsized. Therefore, the mass of the respective coils can be reduced. Taps disposed on the respective coils are arranged to have equal potentials, according to which the external coupling terminals can double as tap switch terminals, so that there is no need to provide a dedicated tap switch. | 09-29-2011 |
