Title: Compound field effect transistor and its manufacture
Inventor: YOKOYAMA TAKAHIRO
IPC: H01L21/338
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of kinks in current-voltage characteristics by absorbing unneeded electric charge due to an electric charge absorption layer even if electron-positive hole pairs are generated by collision ionization in an operation layer and hence obtain high output at a high-frequency region by providing the electric charge absorption layer below the operation layer. SOLUTION: An electric charge absorption layer 24 is provided under an operation layer 26. The electric charge absorption layer 24 is formed by a semiconductor layer of a different conduction type from that of the operation layer 26 and is electrically connected to a source electrode 28, thus absorbing electric charges (positive holes when using an n-type operation layer and electrons when using a p-type operation layer) of inverse polarity from the electric charges that function as carriers in the operation layer 26 out of electron-positive hole pairs being generated due to collision ionization in the operation layer 26 and at the same time discharging them from the source electrode 28 to the outside of an FET and hence suppressing the generation of kinks in current-voltage characteristics.

Title: Optical information recording medium
Inventor: OSADA KENICHI
IPC: G11B7/24
Filed: 1992-06-15
Abstract: PURPOSE:To hardly generate the destruction of a recording thin film by repetition and to obtain a good repetitive characteristic by forming the essential component of a boundary control layer of an oxide formed by combining cation of >=1.0Angstrom  ion radius and O<2-> ion. CONSTITUTION:This information recording medium is constituted by providing the boundary control layer 3 in contact with the recording thin film 4 of the phase transition type optical information recording medium. The essential component of the boundary control layer 3 is composed of the oxide formed by combining cation of the >=1.0Angstrom  ion radius and the O<2-> ion. The reaction of the boundary control layer 3 and the recording thin film 4 hardly arises at the time of irradiation with a laser and some interaction (attraction) acts between the boundary control layer 3 and the constituting material of the recording thin film 4 if the boundary control layer 3 is constituted of such oxide. As a result, the effect of suppressing a material transfer phenomenon is generated between the boundary control layer 3 and the constituting material of the recording thin film 4 and the destruction of the recording thin film is substantially obviated.

Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To record quality images through a simple control even in the case of the occurrence of abnormality in recording elements, by selecting a second recording element having the same assigned recording data as a substitutional element without changing a transportation quantity of the recording medium, in the event where a first recording element used in an ordinary recording operation is determined as operational failure. SOLUTION: An eighth nozzle is supposed to be failed in discharge. Recording data is given relative to only the fifth nozzle to the eighth nozzle in the first forward recording operation, however, ink is discharged to only sixth nozzle, i.e., to only the f line (a). Next, in the backward recording operation, recording paper is transported only for four lines in the B direction. At this time, the recording data corresponding to the fifth nozzle to the eight nozzle in the forward recording operation is allowed to correspond to the first nozzle to the fourth nozzle, and by discharging ink from each first, third, fourth, and sixth nozzle, recording is carried out to respective lines of e, g, h, and j, resulting in the completion of recording operations from e to h (b).  In the hollowing forward recording operation for the second time, recording paper is transported for four lines in the B direction, and ink is discharged to i, k, l, and n lines, so that recording is completed for lines from i to l (c).
