Patent EP-0330625-A3 (EP)
IPC: A61P31/12
Filed: 1989-02-16
Abstract: The present invention relates to :   1) a method for the total synthesis of an indole structure derivative product class,of the triptamine type, in particular of the melatonine or N-Acetyl-5-Methoxy-triptamine type; 2) the use of melatonine or N-acetyl-5-methoxytriptamine as a drug with doses from 2 mg to 20 mg per day,in an oral,intramuscolar or endovenous way; 3) the use of melatonine or N-acetyl-5-methoxytriptamine, in combination with an azidothymidine treating process, in order to improve the curative effects.   The subject total synthesis process consists of combining potassium phthalamide and di-bromopropane in order to obtain 3-bromopropylphthalamide;adding, in the presence of ethanol dissolved sodium,acetacetic esther in order to obtain ethyl-2-acetyl-5-phthalimido-penta noate ;adding diazo-p-anisidine so as to obtain 2-carboxyethyl-3-(2-phthalimidoethyl)-5-methoxy-indole. The main feature of the invention is that to the 2-carboxyethyl-3-(2-phthalimidoethyl)-5-methoxy-indole there are added NaOH 2N and 20% H2SO4 in order to obtain raw 5-methoxytriptamine;which is purified by means of hexamethyldisilazane,with the formation of the related mono and bi-derivative therefrom there is obtained the starting product which is purified by means of aqueous methanol. The subject method,in particular,is specifically designed for provided high purity melatonine,or N-acetyl-5-methoxytriptamine,with a great yield,which is water soluble and may be used for therapeutic purposes. The thus obtained melatonine,has such a purity that it can be used,in suitable packages,both in tumoral phrophilaxy and tumoral terapy,as well as against the acquired immuno-deficiency syndromes,o so called AIDS.

Title: Multiplier
IPC: G06F7/52
Filed: 1990-01-25
Abstract: A multiplier (14) which processes 32 bit operands to 
provide two 16 bit by 16 bit fixed point products or one 32 bit 
floating point product during each clock pulse. Two 16 bit 
by 16 bit fixed point products or one 32 bit floating point 
product are initiated on every clock pulse and results of the 
multiplication process are available after a fixed pipeline 
delay on a continuous basis. The fixed and floating point 
pipeline operations may also be interleaved. The 32 bit input 
operands are selected from three external sources or from the 
last output product. A modified Booth algorithm is implemented 
employing dual parallel processing paths (370, 372) which are 
employed to separately produce the 16 bit by 16 bit fixed 
point products or are combined to produce the 32 bit floating 
point product. Exponent computations are performed in parallel 
in the floating point computational mode.

Title: A semiconductor memory device
Inventor: FUJIWARA ATSUSHI
IPC: G11C11/401
Filed: 1993-02-05
Abstract: A semiconductor memory device with a redundancy configuration
with a higher corrective efficiency is disclosed.
Primary memory cell arrays 3a, 3b, and 3c are arranged in
memory cell blocks a, b, and c. Spare memory cell arrays 2b
and 2c are arranged in the memory cell blocks b and c. When
the address of an address signal supplied agrees with the
address of a defective primary memory cell in one memory cell
block, a spare memory cell in the other memory cell block is
selected for such a defective memory cell. Even if a word
line of the primary and a word line of the spare memory cells
are selected at the same time, it is possible to access read
data in a nondestructive manner. This achieves a high-speed
word line activation as well as an improved corrective efficiency.
The provision of a row decoder that connects a
primary word line to a spare word line with a shared decode
line prevents the increase of the area of memory chips due to
the arrangement of a spare memory cell.

Filed: 1996-09-16
Abstract: A reproduced signal is digitized so as to count
a time interval of a specified pattern simultaneously
with the count of a clock period of a phase lock loop
circuit. A phase lock loop clock frequency is subjected
to a feedback control based on the information indicating
the difference between the time interval and the clock
period. In this manner, a frequency loop performs a
feedback operation so that a frequency of the reproduced
signal falls within a capture range of a phase lock-in,
thereby increasing the speed of phase lock-in.
