摘要:
An optical information record carrier (optical disk, conventionally) has multiple reflective surfaces, each carrying separate information and each readable by an optical beam directed from the same side of the record carrier. The top most reflective surface reflects light of a first waveband and passes light of a second waveband. The next top most reflective layer reflects light within at least part of the second waveband. The record carrier is formed by producing a first reflective layer having a first pit pattern in the surface of a transparent substrate, pressing said first subtrate/layer combination to a transparent stamper having a second pit pattern, with a radiation hardening liquid resin therebetween, irradiating the resin by applying radiation to said resin through said stamper, peeling off said stamper, applying a second reflective layer to said hardened resin surface opposite the surface in contact with said first reflective layer, and applying a protective layer to said second reflective layer.

摘要:
A method for manufacturing a double-sided-multi-layered optical disc. An intermediate substrate having pits on both the major surfaces is previously prepared as well as first and second substrates. The method rotates the first substrate, the intermediate substrate and the second substrate with respect to the common center thereof so as to form unhardened radiation setting resin layers between adjacent substrates so that thicknesses of the unhardened resin layers are adjusted to predetermined values, and then the method irradiates a radiation onto the unhardened resin layer so as to harden the unhardened resin layers to solid resin layers.

摘要:
The cables are configured to supply electric power from an inverter to a motor. The cables include a connector and plural terminals fixed to the connector. A housing of the connector includes a first rib, provided between the adjacent terminals, connecting mutually facing surfaces of the housing. The terminal block is attached to an enclosure of the inverter or motor. The terminal block includes plural retaining walls, each of which encloses and retains a nut. The terminal block includes a second rib connecting adjacent retaining walls. One of the first and second ribs includes a recess. The connector is connected to the terminal block when each of the terminals is fastened to the terminal block with a bolt and the nut. The other of the first and second ribs is disposed in the recess and the ribs intersect when the connector is connected to the terminal block.
