Title: Semiconductor laser device having plurality of layers for emitting lights of different wavelengths and method of driving the same
IPC: H01S5/06
Filed: 1990-03-29
Abstract: A semiconductor laser device capable of emitting lights of 
different wavelengths has a substrate (1), a first light-emitting 
layer (11a) provided on the substrate (1), and a second 
light-emitting layer (11b) provided on the substrate (1) and having a 
greater band gap than the first light-emitting layer. A 
barrier layer (12) is disposed between the first and second 
light-emitting layers (11a, b). The barrier layer (12) has a band gap 
greater than those of the first (11a) and second (11b) light-emitting 
layers. The band gap and the thickness of the barrier 
layer (12) are determined to be large enough to create, in 
response to injection of carriers to the light-emititng 
layers, a state in which the carrier density in the second 
light-emitting layer (11b) is made higher while the carrier 
density in the first light-emitting layer (11a) is made lower 
than those which would be obtained when the barrier layer (12) 
is omitted. The device further has a pair of cladding 
layers (3, 5) sandwiching therebetween the first light-emitting 
layer (11a), the barrier layer (12) and the second light-emitting (11b) 
layer, the cladding layers (3, 5) having smaller refractive index 
values than the first and second light-emitting layers (11a, b). 
The device further has electrodes (7, 8) for supplying electrical 
currents to the first and second light-emitting layers (11a, b).

Filed: 1990-04-24
Abstract: The present invention provides a crystal 
modification of magnesium salt of mono-p-nitrobenzyl 
malonate (hereinunder referred to as "β-type crystal") 
which is characterized by an X-ray diffraction pattern 
having strong peaks at angles of diffraction of (2ϑ) [°] 
4.5, 8.9 and 13.3 according to X-ray diffractometry with 
Cu-Kα line, and a process for producing the β-type 
crystal modification of magnesium salt of mono-p-­
nitrobenzyl malonate comprising the step of reacting a 
water-soluble magnesium salt with an alkali metal salt or 
ammonium salt of mono-p-nitrobenzyl malonate. 
This process facilitates the production of the β-type 
crystal modification having a higher purity than a known 
α-type crystal modification. 
The β-type crystal is a very useful intermediate as a 
starting material of pharmaceutical.

Patent EP-0669299-A3 (EP)
Title: Reinforced concrete structure.
Inventor: BROWN CARL W JR
IPC: C23F13/12
Filed: 1995-02-03
Abstract: A metal coating of typically a valve metal, especially a titanium metal coating, is applied by thermal spraying to the surface of concrete, most particularly steel-reinforced concrete. The metal such as titanium may be sprayed by any one of several thermal spraying techniques including flame spray, electric-arc spray, plasma spray, high-velocity oxyfuel spray, or detonation gun spray. The metal coating should be tightly adhered to the concrete and desirably will have a porosity to facilitate extensive coating of the metal itself, as well as facilitate any activation that may be needed for the metal. Such activation can be in the form of an active material which allows the coating to function catalytically. One coating option is to apply a solution onto the spray-applied metal, then polarize the metal anodically to effect deposition of active material on the metal. Another option includes depositing active material directly onto the concrete, then applying an adherent, electrically conductive overlay such as a titanium metal coating to the treated concrete.

Abstract: A clustering technique groups manufacturing data in clusters of
similar parametric behaviour. Each cluster groups data points which
satisfy a given criterion of process behaviour similarity. These data
may be widely separated in time and thus need not form time ordered
clusters. The technique operates in multi-dimensional parameter space and
can represent process data that is characterised with multiple
performance measures. The technique produces a partition of the data
into the minimum number of clusters which satisfy the criterion that all
data in the grouping are within a given threshold distance from a cluster
nucleus. In addition, the clustering mechanism according the invention
