Title: 800 number call back
Inventor: KESHAV SRINIVASAN
IPC: H04M3/51
Filed: 1997-07-16
Granted: 2000-06-27
Abstract: A method and system for handling incoming calls when no destination stations are available. When an incoming call from an originating station is received, it is determined  whether a destination station is available. If a destination station is not available, a telephone number of the originating station is stored, Shortly before its current call is concluded, a destination station indicates its approaching availability. Responsive to this indication, an outgoing call is placed to the originating station. If the originating station does not answer the outgoing call within a predeternined time, the outgoing call is terminated and rescheduled. If the originating station answers the call within apredetermined time, the outgoing call is connected to the available destination station.

Title: Improved method for reverse transcription
Inventor: HAYASHIZAKI YOSHIHIDE
IPC: C12P19/34
Filed: 1997-07-24
Granted: 2008-04-22
Abstract: A method for preparing a cDNA from a mRNA using a reverse transcriptase wherein reverse transcription is performed at a temperature at which the mRNA does not take a secondary structure, for example, at a temperature of 45°C or more. The method is performed, for example, using a heat-labile reverse transcriptase in the presence of a substance exhibiting chaperone function having chaperone function such as saccharides. The method is performed, for example, in the presence of metal ions necessary for activation of the reverse transcriptase and a chelating agent for the metal ions such as a deoxynucleotide triphosphate. The method is capable of reverse transcription over the full length of mRNA template even if the mRNA is a long chain mRNA and, as a result, producing a full length cDNA.

Granted: 2004-11-02
Abstract: The invention relates to a clamping device, in particular to a cable clamping device for telecommunications technology and data systems technology. The object of the invention is to develop a clamping device of the generic type which ensures that objects having different diameters are clamped simply and reliably and without the risk of an impermissibly high degree of pinching of the object. This is achieved by using a clamping device having a clamping member with a basic body and at least one clamping arm extending from the side of the body.    The object to be clamped is inserted into the clamping member. The clamping device also has a sleeve having cutouts into which at least one of the clamping arms of the clamping member engages. By rotating the sleeve relative to the member, the at least one clamping arm reduces a clamping inside-diameter of the clamping member.

Abstract: An airflow rate regulating device which is installed in a vacuum unit that collects contaminants from a processing station in a controlled space. This device enables a vacuum unit to maintain a continuous suction of contaminant particles from a processing station when there are pressure variations in the controlled space. The airflow rate regulating device is mounted in a suitable cabinet 88 and connected to a vacuum source, the airflow rate regulating device has a casing divided into two chambers separated by a wall having an passageway through which air flows from one chamber to the next. Each chamber features an airflow rate regulation valve comprising a movable member extending across the flow of air passing through the casing, that can be adjusted using counterweights. When a pressure disturbance occurs in the controlled room from a door opening, or when a hose leading the contaminant source is disconnected, the airflow rate regulation valves react to maintain sufficient vacuum pressure at the contaminants source. Since the airflow rate regulating device is mechanical, its response time to pressure is nearly instantaneous.

Abstract: Cette invention concerne un échangeur de chaleur dans lequel des premières plaques d'échange thermique (S1) et des secondes plaques d'échange thermique (S2) sont disposées de manière radiale entre une enceinte externe, cylindrique et de grand diamètre (6) et une enceinte interne cylindrique d'un diamètre réduit (7). Ces plaques définissent des passages pour les gaz de combustion (4) et des passages pour l'air (5) qui sont alternés dans le sens de la circonférence. Une multitude de protubérances (22, 23) sont formées sur les deux surfaces des premières (S1) et secondes (S2) plaques d'échange thermique, et se rejoignent au niveau de leur pointes. Les pas (P) entre les protubérances adjacentes (22, 23) sont modifiés dans le sens radial de manière à conserver un nombre sensiblement constant d'unités de transfert de chaleur dans le sens radial. Les répartitions de températures peuvent ainsi être uniformisées sur les premières (S1) et secondes (S2) plaques d'échange thermique dans le sens radial. Ce système permet d'éviter toute chute de l'efficacité de l'échange thermique, et d'empêcher la génération de contraintes thermiques indésirables.

Abstract: In the apparatus for cooling a superconductor (1) in accordance with the present invention, a male thread portion (31) of an inner container (3) engages a female thread portion (21) of an outer container (2) so as to connect the inner and outer containers (2, 3) to each other. Also, the bottom wall of the inner container (3) is provided with a thermal conductor (6) penetrating therethrough. Further, a sapphire sheet (23) is joined to peripheral portions of an opening of the bottom wall of the outer container (2) facing the thermal conductor (6), so as to block the opening (26). As the distance between the bottom wall of the outer container (2) and the bottom wall of the inner container (3) is freely adjusted by changing the engaging position between the thread portions (21, 31), the gap between a high transition temperature (high-T c) superconducting magnetic sensor (7) and the sapphire sheet (23) is adjusted. Therefore, the number of components is reduced as compared with that conventionally needed. Also, the performance of cooling the (high-T c) superconducting magnetic sensor (7) can be improved. Further, since the inner container (3) and the outer container (2) are easily attached and detached, whereby workability is improved as compared with that in the conventional ones.
