Title: Device and manufacture of group iii nitride semiconductor light emitting element
Inventor: KOIDE NORIKATSU
IPC: H01L21/205
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a structure of single or multiple quantum wells having excellent crystalline property for a light emitting layer. SOLUTION: A grown substrate is moved between a first heating stage 20a heated to the first temperature and a second heating stage 20b heated to the second temperature, which are provided in the same reaction chamber. When the barrier layer of a light emitting layer is formed, the grown substrate is moved to the first heating stage 20a, and the barrier layer is grown. When the well layer of the light emitting layer is formed, the grown substrate is moved to the second heating stage 20b, and the well layer is grown. Thus, the requirements for the temperature rising time until the migration to the relative high temperature and the temperature decreasing time unit the migration to the relatively low temperature are avoided. Therefore, the time, in which the well layer grown at the relatively low temperature is exposed to the growing temperature of the barrier layer that must be grown at the relatively high temperature, becomes short. Thus, the crystal property of the well layer is improved. In this way, the quantum-well structure, in which the band structure steeply changes and the quality is excellent, is obtained.

Title: Electrode forming method
Inventor: KOIKE KENICHI
IPC: H01L21/338
Filed: 1992-07-30
Abstract: PURPOSE:To greatly reduce the damage caused to a substrate by etching a metal silicide film with use of mixed gas of CF4 and O2, and changing the mixed gas to SF gas when the etched depth reaches the lower layer part of the metal silicide film. CONSTITUTION:A WSi film 2 for forming an electrode is accumulated, for example, by 3000Angstrom  on a GaAs substrate 4 on which an activated layer 3 is formed. After that, a resist pattern 1 for forming an electrode is formed in a predetermined position on the WSi film 2. Next, it is etched with the mixed gas of anisotropic CF4 and O2 until the residuary thickness of the WSi film 2 becomes nearly 500Angstrom . Thereby, the WSi film 2 may be vertically worked like the resist pattern 1. And the mixed gas is changed to SF6 to remove the residuary WSi film 2. Since the SF6 gas is isotropic, there is no possibility that damage is caused to the surface of the GaAs substrate.

Title: Alarm deterring method and alarm deterrence reporting device
Inventor: TEZUKA KOJI
IPC: H04L69/40
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To make a downstream device generate no alarm even when detecting cycle abnormality as to a signal from a powered-OFF device by making a device which detects a break of power supply send an alarm deterrence report corresponding to the powered-OFF device downstream periodically. SOLUTION: When a terminal 21 is normally powered OFF, a network terminal device 20 detects the power-OFF state and sends an REC-INH signal to a station side as power-OFF information. A subscriber line terminal device 10 on the station side detects a stop of ATM cells from the terminal 21, but receives the REC-INH signal at the same time, so it judges that the stop results from the normal power-OFF state and deters the cycle abnormality being alarmed. The subscriber line terminal device 10 once receiving the REC-INH signal from the subscriber side generates an OAM cell indicating the alarm deterrence at a constant period and sends them out downstream through an ATM repeater 13. A CLAD device 21 detects the stop of ATM cells from the terminal 21, but receives the OAM cell indicating the alarm deterrence, thereby deterring an alarm being generated.

IPC: B41J2/26
Filed: 1987-08-17
Abstract: PURPOSE:To make it extremely easy to connect printing wire and an armature and thereby reduce manufacturing cost by forming printing pin attached to the printing wire by using a shape memory alloy and machining one end of the pin into the form of a stopper. CONSTITUTION:One bifurcated end 12a of printing pin 12 is machined into the form of a stopper by bending each split half to an L form and spreading them. Next, shape memorizing treatment is performed on this printing pin 12 of that form. After this, apparent plastic treatment is applied to the one end 12a of the printing pin 12 to cause the end to be restored to a substantially original form at temperature below the phase transformation point of shape memory alloy. Then the one end 12a of the printing pin 12 is inserted into a retaining hole 2a opened in advance on an armature 2. After this, the one end 12a of the printing pin 12 is heated to temperature above phase transformation temperature. Consequently, the one end 12a of the printing pin 12 is transformed into the form of a stopper by shape memory effect, thus connection of the printing pin and the armature 2 is effected in undetachable manner.
