Patent EP-0383233-A3 (EP)
Title: Ultrasonic probe and acoustic lens attachment
IPC: B06B1/06
Filed: 1990-02-12
Abstract: An ultrasonic probe disclosed in this invention 
includes an ultrasonic probe body (10) and an acoustic lens 
attachment (20) detachably fitted on the ultrasonic probe 
body (10). The attachment (20) includes an acoustic lens (16), and 
the lens (16) is in contact with electrical/acoustic trans­
ducer elements (12) formed in the probe body (10) but is partially 
separated from the probe body (10) to form air gaps (40). The 
air gaps (40) constitute escape portions, respectively. The 
air gaps (40) are defined by parts of acute-angled surfaces 
of the probe body, obtuse-angled surfaces (28) of connecting 
portions of the attachment (20), and tight contact portions (22) 
of the attachment (20). The tight contact portions (22) are 
perfectly in tight contact with the probe body (10), so that 
a medium (50) is moved to the escape portions (40). The medium (50) 
can be uniformly spread to form a thin medium layer. 
Bubbles are not formed in the tight contact portions, 
and the acoustic lens (16) does not locally project. A 
two-dimensionally uniform acoustic refractive index can 
be obtained.

Patent EP-0403797-A3 (EP)
IPC: G11B7/244
Filed: 1990-05-16
Abstract: Certain types of aryl nitrogen compound are found to be 
useful not only for effectively rendering dyes lightfast but 
also for using as an additive that has high solubility in sol­
vents and sufficiently good miscibility with dyes to insure 
that their solubility will not be impaired. They can be used 
for preventing various reactions that cause deterioration by 
light in organic dyes, in particular cyanine dyes. They can 
also be used for improving the keeping quality and recording 
and reproduction characeristics of optical recording media 
that use organic dyes in the form of thin films. Representa­
tive examples include N, N-lower alkyl substituted nitroso­
anilines, phenol or naphthol derivatives having at least one 
nitroso group, nitrosodiphenylamine and its derivatives and

Title: Object with a temperature-indicator
IPC: G01K11/06
Filed: 1990-12-04
Abstract: The invention relates to a heat-shrinkable article that is at least partially coated with a temperature indicator. This temperature indicator is composed of an organic polymer having a suitable bonding agent, whereby the organic polymer is contained therein in a finely ground condition. As a result of this condition, the appearance of the agent is opaque and has a color corresponding to the degree of granulation and material constituent. When the melting point of the composition is reached, the material melts and becomes transparent or at least translucent. The color of the article shows through, so that this color change can be interpreted as a temperature indication.
Patent EP-0380191-A3 (EP)
Title: Method and apparatus for altering the access format of telephone calls
IPC: H04M15/30
Filed: 1990-01-19
Abstract: A telephone system and method of operation are 
disclosed which use a microprocessor control system (10), 
a speech generator (34) and speech memory (46) to 
automatically place calls without the need of a live 
operator. The telephone receives a destination telephone

Title: Tape cassette with tape leader detection improvements
IPC: G11B23/087
Filed: 1990-05-11
Abstract: An optical tape leader detection system 
includes a light source and a light detector. In a 
video cassette using opaque magnetic tape, the tape 
follows a defined tape path and has a transparent 
leader at each end thereof, with the free ends of the

aperture in the cassette cover is adapted to receive 
the light source. A window is provided in the 
cassette cover, allowing light emitted from the light 
source and passing through the transparent leader 
portion to reach the light detector along a defined 
light path. One or more light pipes are mounted in 
the cassette cover and aligned to define portions of 
that light path, thereby controlling the source and 
amount of light with respect to the light detector.

Title: Process for preparing neotrehalose and its uses
IPC: A23L27/30
Filed: 1991-11-14
Abstract: Neotrehalose is prepared in a relatively high-yield by a process comprising allowing  beta -galactosidase to act on a solution containing lactoneotrehalose to form neotrehalose and recoverying the resultant neotrehalose. The neotrehalose is a non-reducing oligosaccharide having a satisfiable stability and a rich- and high-quality-sweetness and is assimilated and utilized as energy source in vivo when orally administered. Neotrehalose in the form of crystal has a satisfiable handleability because it is readily soluble in water and substantially free of hygroscopicity. These render neotrehalose very useful in the fields of food-, cosmetic- and pharmaceutical-industries.
