Patent EP-0415018-A1 (EP)
Inventor: RAPAPORT ELIEZER
IPC: C07H19/20
Filed: 1990-06-22
Abstract: Administration of adenine nucleotides to a host is followed by their rapid degradation to adenosine and inorganic phosphate which promote increases in liver ATP pools. The turnover of expanded liver ATP pools supply the adenosine precursor for the subsequent expansions of red blood cell (total blood) and blood plasma (extracellular) ATP pools. Thus, the administration of AMP, ATP or their degradation products adenosine and inorganic phosphate to a host, achieve the beneficial increases in liver, total blood and blood plasma ATP levels.

IPC: H01L31/107
Filed: 1990-01-05
Abstract: Disclosed are an avalanche photodiode and a manufacturing method thereof. An n⁻-type InGaAs light absorption layer (13) and n⁻-type InP window layer (15) are formed on an n-type InP substrate (11) by crystal growth, in the order mentioned. A depression is formed in a selected surface portion of the window layer, and n-type impurities are doped into the bottom of the depression, to thereby form an n-type high concentration region (16). Further, n⁻-type crystal-­grown InP layer is formed in the depression in such a way as to fill the depression. A guard ring (19) is formed around the depression by the doping of p-type impuri­ties. By doping p-type impurities into the window layer, a p-type high concentration region (18) is formed in the window layer in a manner completely surrounding the interface between the n-type high concentration region and the crystal-grown InP layer. The n-type and p-type high concentration regions define a junction serving as a light-receiving region. Since the inter­face of the crystal-grown InP layer, which may not have a satisfactory crystalline structure, is located within the p-type high concentration region, that interface is not supplied with a high electric field during use. Accordingly, the performance of the avalance photodiode is not influenced by the interface.

Abstract: An ultrasonic sensor (10) for fluid levels comprises a carrier having spaced-apart legs with registering openings adapted to receive a piezoelectric transmitter and a piezoelectric receiver in the openings. The piezoelectric members are separated by the spaced legs of a ground plane engaging plates of the piezoelectric members. Resilient members in the form of coiled conductors are entrained between a snap-on cover and the transducers so as to resiliently engage the piezoelectric members against the ground plane. The conductors are coupled by crimp connec­tors to the leads of a cable carried by an elongated channel portion of the carrier. The crimp connectors are carried in recessed portions of the carrier, and the carrier is over-molded to encase the connectors and the cable (16). The cable (16) is in turn coupled to an electronic control module (18) positioned remotely from the fluid sump and connected to a warning device (20).

Abstract: A fire-resistant fabric suitable for use as a flame barrier comprising a flame durable textile fabric substrate (20) formed of corespun yarns (10), the yarns (10) comprising a core (11) of flame resistant fiber and a sheath (12) of modacrylic intumescent staple fibers. In normal use, the fabric is flexible and conformable and has good air porosity.

Abstract: A process for fabricating cermet electrodes for solid oxide electrochemical cells by sintering is disclosed. First, a porous metal electrode is fabricated on a solid oxide cell, such as a fuel cell by, for example, sintering, and is then infiltrated with a high volume fraction stabilized zirconia suspension. A second sintering step is used to sinter the infiltrated zirconia to a high density in order to more securely attach the electrode to the solid oxide electrolyte of the cell. High performance fuel electrodes can be obtained with this process. Further electrode performance enhancement may be achieved if stabilized zirconia doped with cerium oxide, chromium oxide, titanium oxide, and/or praseodymium oxide for electronic conduction is used.
