Title: Distributed feedback semiconductor laser
Inventor: YOSHIDA TOMOHIKO
IPC: H01S5/12
Filed: 1986-10-08
Abstract: PURPOSE:To reduce reflectivity on an end surface, and to inhibit the unnecessary oscillation of a Fabry-Perot type resonator mode by forming the outgoing surface of beams in parallel with the growth direction of double hetero-structure and inclining the outgoing surface of beams only by a fixed angle to the direction of propagation of beams. CONSTITUTION:Since the electric field of laser beams is made parallel with a (100) face, the direction of polarized light is also made parallel with the (100) face. Consequently, laser beams are projected at a Brewster angle to an outgoing surface 10, and hardly reflected. Laser beams, an electric field of which is made perpendicular to the (100) face, normally exist in one part of laser beams, but the outgoing surface 10 functions as a high reflecting surface to such laser beams, and the laser beams are reflected in the direction of propagation of laser beams and in the direction 20 of 2X(90 deg.-theta), thus removing output laser beams output from the outgoing surface 10, then acquiring an output having excellent polarized-light purity.

Title: Time multiplexing highway line designation system
Inventor: TABU TAKASHI
IPC: H04J3/00
Filed: 1991-09-19
Abstract: PURPOSE:To improve the maintenance performance and to reduce number of wires by allowing a line adaptor section to store time location information specific to a line and generating a timing of the line. CONSTITUTION:A storage means 2 in a line adaptor section 1 stores to which position in a highway a line belongs and a timing circuit 3 generates a strobe signal corresponding to the position. The generation of the signal confirms a position with respect to time multiplexing corresponding to the line adaptor section. When one time slot consists of plural data, position information putting the line adaptor sections 1 together is generated based on a timing generated from a line common section 4. Since the position information corresponding to each line is stored respectively in the line adaptor section 1, an object location timing is obtained by applying only a basic clock to the line adaptor section 1 and when plural timings are required for one line, the line common section 4 gives a timing to each line in common.

Title: Duplexing control system
Inventor: AOYAMA HIDEO
IPC: G06F15/16
Filed: 1987-09-24
Abstract: PURPOSE:To avoid the interruption of the overall processing of a device caused by a system switching action by using a switch deciding means which decide whether a device including a faulty processor should be switched to a spare device or not by reference to the information on importance and in accordance with the degree of importance. CONSTITUTION:A decentralized processing system is obtained by duplexing a device which consists of plural processors 10-14 and 20-24 and performs the decentralized processing. In this system the information showing the degrees of importance of the processors 10-14 and 20-24 forming a 0-system packet exchange device 1 and a 1-system packet exchange device 2 respectively are previously stored. When either one of those processors 10-14 and 20-24 has a fault, the switch is carried out between both devices 1 and 2 only when it is decided that the faulty processor contains an important function by reference to the information on the importance of the relevant processor. Thus it is possible to avoid the interruption of the decentralized processing of a system as a whole when a processor containing no important function has a fault.

Title: Semiconductor integrated circuit device
Inventor: HIRANO YOSHIYUKI
IPC: H01L21/28
Filed: 1983-12-20
Abstract: PURPOSE:To eliminate the rise of a contacting resistance and an aluminum spike phenomenon in a semiconductor integrated circuit device in which an interval between a diffused layer and a contacting hole is formed ultrafinely by forming a barrier metal layer for preventing silicon and aluminum from reacting in a contacting region. CONSTITUTION:A hole 7 of an interlayer insulating film 5 is formed in a diffused layer 6', and a barrier 9 for preventing aluminum and silicon from reacting is formed on the surface of the layer 6'. The barrier metal employs titanium (Ti)-tungsten (W) or titanium nitride (TiN). At this time, the layer 6' of the contacting portion has the same depth as a wiring diffused layer 4, and less lateral diffusion. Accordingly, even if the two diffused layers are narrowed at the interval, the withstand voltage can be maintained. The layer 6' may be formed simultaneously with the layer 4 in the same depth of relatively shallow depth. Thus, a lateral extension is less, and the extension of a depletion layer 36 is small, and even if the layer 36 is extended, the withstand voltages of the layers 6', 4 can be sufficiently obtained.
