摘要:
The printing sheet of the invention comprises a base sheet and two successive coating layers provided thereon, of which the first coating layer, which serves as a water-absorbing layer, is formed of a dispersion of a powdery highly water-absorptive resin, e.g., poly(sodium acrylate), in a polymeric vehicle and the second coating layer, which serves as a water absorption-controlling layer, is formed of a dispersion of an inorganic powder such as silica in a polymeric vehicle. By virtue of the adequately controlled velocity and capacity of water absorption, the printing sheet can give a very satisfactory printed matter in respect of the color density and sharpness of the printed patterns when it is used in printing on an ink-jet printer by using an aqueous ink.

An apparatus for automatically adjusting the playback position of the magnetic data recording device of the kind in which a rotating magnetic head is contacted with a stationary recording tape for recording the data on the tape and the tape is then advanced a predetermined length for recording the next data on the recording tape. The apparatus is designed to prevent the non-registration between the playback head position and the recorded zones of the tape and, to this end, a differential gearing is provided between the capstan shaft adapted for reeling out or unwinding of the tape and the driving shaft for said capstan shaft and operated to compensate for any non-registration between the playback head position and the recorded zones of the tape and automatically bringing the playback head at the edge of the recorded zone in the tape in good timing with the feed of the tape.

A p-type GaN guiding layer, an n-type GaN layer, and an n-type AlGaN current blocking layer are sequentially formed over an active layer, and then part of the current blocking layer is etched by using an alkali solution and irradiating the part with light to form an opening. Thereafter, a second p-type GaN guiding layer is formed on the current blocking layer to cover the opening. In this structure, the GaN layer has a smaller energy gap than the AlGaN current blocking layer.

A nitride semiconductor device includes an active layer formed between an n-type cladding layer and a p-type cladding layer, and a current confining layer having a conductive area through which a current flows to the active layer. The current confining layer includes a first semiconductor layer, a second semiconductor layer and a third semiconductor layer. The second semiconductor layer is formed on and in contact with the first semiconductor layer and has a smaller lattice constant than that of the first semiconductor layer. The third semiconductor layer is formed on and in contact with the second semiconductor layer and has a lattice constant that is smaller than that of the first semiconductor layer and larger than that of the second semiconductor layer.
