Title: Duplex circuit system
Inventor: KATO YOSHITAKA
IPC: H04B1/74
Filed: 1986-10-22
Abstract: PURPOSE:To decrease the number of lines required for confounding paths by inserting a tri-state buffer to the confounding path in a changeover means confounding an active system and a standby system. CONSTITUTION:The tri-state buffers 10, 11 in the active system 1 and the standby system 2 are connected respectively to the sending end of pre-stage circuits 3, 4 each and controlled by a switching control signal 7.

Title: Semiconductor optical amplifier
Inventor: SHIBATA YASUO
IPC: G02B6/14
Filed: 1991-09-30
Abstract: PURPOSE:To enable attainment of a small-sized integration and to facilitate manufacture by a method wherein two gain regions each having a semiconductor laser structure and a first TE-TM mode conversion region constructed, between these gain regions, of a waveguide having perturbation being asymmetric in vertical and lateral directions are connected with each other in the direction of a guided light. CONSTITUTION:When a signal light enters a gain region A1, a TE mode is amplified in this region. This signal light enters a TE-TM mode conversion region B. This region is so formed that perturbation in the vertical direction is asymmetric laterally, and therefore coupling occurs between the TE mode and a TM mode. This perturbation is formed periodically and phases of the TE mode and the TM mode are matched each other. While the TE light entering the conversion region B is propagated through this region, the plane of polarization of the signal light is rotated at 90X(2n+1) degrees. This signal light enters a gain region A2. The signal light entering the region A2 becomes a signal light of which a TM component is amplified apparently. The signal light is amplified with respect to a TE component in the main in the region A2.

Title: Recording head
Inventor: HANATO HIROYUKI
IPC: B41J2/32
Filed: 1988-10-05
Abstract: PURPOSE:To prevent a sag at both ends of a recording head due to grinding from spreading to the row of electrodes and ensuring uniform printing by providing a dummy pattern formed of the material same as electrodes and in the same shape, on both ends of the row of electrodes. CONSTITUTION:The recording head of an energized transfer recording device has a recording head substrate 10 and the row of electrodes 12 consisting of needle-like recording electrodes 11, and a dummy pattern 13 (oblique-lined part) is provided on an area adjacent to both ends of the row of electrodes 12. The row of electrodes 12 abrades due to the sliding of the row on the resistance layer of recording film. Therefore, the recording electrode 11 is ground using a lapping sheet to ensure a satisfactory contact between the row of electrodes 12 and the recording film. Only the tip 14 of the dummy pattern 13 is extensively ground (shown by D), and the entire tip area of the recording electrode 11 is uniformly ground. Then no sag generates on the tips of both ends of the electrodes 12 in row. Consequently, it is possible to prevent the sag which generates on both ends at the tip of the recording head during grinding from spreading to the row of electrodes, and thus ensure uniform printing.
