Abstract: A preventive maintenance system of a machine tool capable of making determination of presence of an abnormality mechanically and automatically, which has conventionally been performed on the basis of the feeling of an operator and detecting an abnormality more accurately in an earlier stage is provided.

Abstract: A tool management system of a machine tool includes: a detection unit to detect at least one of vibration, acoustic waves produced during operation of the machine tool, and current value of a server motor of a driving machine tool; a tool replacement determination unit that determines the necessity to replace the tool on the basis of information related to a detection value of at least one of the vibration, the acoustic waves, and the current value detected during operation of the machine tool; and a detection start/end command setting unit that adds commands for a detection start point and a detection end point of at least one of the vibration, the acoustic waves, and the current value of the servo motor to a machining program.

Abstract: A tool management system of a machine tool capable of determining an appropriate time to replace a tool used by a machine tool is provided.

Abstract: Disclosed is a film-forming coating solution comprising a matrix and a fine particulate compound oxide composed of oxides of titanium, silicon and zirconium and/or aluminum. This film-forming coating solution can form a colorless and transparent film of high refractive index which is excellent in dyeing property and adhesion to the substrate. Also disclosed is a synthetic resin lens of high refractive index having a film (hard coat film) formed from the film-forming coating solution on the surface. This synthetic resin lens is free from interference fringe and has a reduced thickness.

Abstract: A mechanism for winding camera film includes a small size reduction gear which includes an internal gear rotatably mounted within the camera, an output shaft mounted on the internal gear to rotate therewith, and a cylinder coupled to the output shaft to rotate with the output shaft for receiving and winding film thereabout, the internal gear being a stationary internal gear; a movable internal gear having an internal gear, plane gears in mesh with the stationary internal gear and the movable internal gear. A holder and a holder clamp hold the plane gears. A sun gear meshing with the planet gears is directly connected with a motor shaft. The reduction gear includes a column beam provided between columns extending upwardly from the holder and, further, guide sections are provided in those sections where the movable internal gear and the stationary internal gear are in contact with each other.

Abstract: A wrist mounted electronic device, including a loop antenna embedded within a single-injection molded, multiple-segment wristband, has an electrically conductive, obtusely angled mounting bracket disposed between an embedded antenna and the electronic device. The mounting bracket has at least one screw hole to facilitate attachment of the wristband segments to the electronic device. The embedded antenna has a plurality of round holes therethrough.

Abstract: A small-sized reduction gear includes: a stationary internal gear 10; a movable internal gear 20 having an internal gear; planet gears 12 in mesh with the stationary internal gear 10 and the movable internal gear 20; a holder member 15 and a holder clamp 19 which hold the planet gears 12; and a sun gear 4 in mesh with the planet gears 12 and directly connected with a motor shaft 3. The reduction gear further includes a column beam 18 provided between columns extending upwardly from the holder member 15 and, further guide sections provided in those sections where the movable internal gear 20 and the stationary internal gear 10 are in contact with each other. This construction helps to provide a small-sized reduction gear which makes it possible to obtain a high reduction ratio with a very small number of parts, which has a high level of transmission efficiency, which involves little backlash and noise, and which excels in dustproofness and can be produced at low costs.

Abstract: A method of forming an integral intermediate layer in a flexible single injection molded component is disclosed. According to the method a strip comprising the sandwiched layer is securely positioned within a molding cavity. During injection of the mold material a tensile force is applied throughout the strip in a plane orthogonal to a critical component direction. The method is particularly suited for the fabrication of wrist mounted electronic devices having an electrical connection to a conductive member integrally housed within a molded wristband.
