Title: Bone-associated transcription control factor-like protein and process for producing the same
Inventor: OKAZAKI MAKOTO
IPC: C07K16/00
Filed: 1994-03-09
Abstract: Abstract of the Disclosure Bone-associated proteins derived from bone of mammals including mice, human beings, named OSF-6. The protein is the novel natural type mammal protein which can play an important role in bone formation and belongs to a group of transcription control factors.  OSF-6 can be used as a therapeutic agent for bone metabolic diseases and also as a diagnostic agent for bone metabolic diseases since it may demonstrate a high organ specificity to bone.

Abstract: METHOD AND APPARATUS FOR ATTACHING A FASTENER TO AN ENCLOSED STRUCTURE     ABSTRACT OF THE DISCLOSURE The disclosed method and apparatus is adapted to attach a self-attaching fastener, such as a pierce or clinch nut or stud to a metal wall of an enclosed structure, such as a tube, from inside the structure. The method includes rigidly supporting the self-attaching fastener within the enclosed structure on an anvil with the fastening portion extending toward and located adjacent an inner surface of the wall. A die member is then driven against the outer surface of the wall to deform the wall into locking engagement with the self-attaching fastener. Where a pierce nut or stud is used, the nut simultaneously pierces the wall from inside the structure and clinches the wall as the die member is driven against the outer surface of the wall. The apparatus includes an expandable anvil assembly having opposed surfaces which conform generally to the opposed surfaces of the enclosed structure and a pocket which receives and rigidly supports the body portion of the self-attaching fastener. The anvil assembly further includes relatively movable parts having mating inclined surfaces and the parts are moved to expand or contract the anvil assembly. The method then includes inserting the body portion of a self-attaching fastener in the anvil pocket, inserting the anvil in the enclosed structure, then expanding the anvil to locate or position the fastener adjacent the inner surface of the wall. The die member then installs the nut in the wall. Finally, the anvil is contracted to remove the anvil from the assembly.

Filed: 1993-06-24
Abstract: A telecommunications testing apparatus comprising a signal generator (7) which generates a speech-like synthetic signal, which is supplied to the input of a telecommunication apparatus (1) to be tested. The distorted output of the telecommunications apparatus (1) is supplied to an analysis means (8), which derives, for both the undistorted test signal and the distorted signal from the telecommunications apparatus (1), a measure of the excitation of the human auditory system generated by both signals, taking into account both spectral masking and temporal masking phenomena. The difference between the two excitations is then calculated, and a measure of the loudness of the difference is derived which is found to indicate to a high degree of accuracy the human subjective response to the distortion introduced by the telecommunications system.

Title: Precombustion chamber device
Inventor: KUHNERT DIETER
IPC: H01T13/54
Filed: 1995-03-13
Abstract: A precombustion chamber ignition device for preferably lean fuel-air mixtures and having a precombustion chamber. This precombustion chamber contains a electrode carrier extending into the precombustion chamber and on it at least one ignition electrode is attached, which has at least one ignition portion, which cooperates with a internal wall surface of the precombustion chamber in defining at least one spark gap extending substantially athwart the longitudinal axis of the precombustion chamber. In this respect the internal wall surface acts as a ground electrode. The ignition portion of the at least one ignition electrode is offset in relation to the longitudinal axis of the precombustion chamber and is arranged essentially parallel to the wall surface, which is substantially cylindrical in the spark gap portion, of the precombustion chamber close to the wall surface. In consequence it is possible for the ignition potential to be reduced and in the case of long term operation for the working life of the precombustion chamber ignition device to be in-creased. More particularly however the reliability of flaming is a substantially improved in the case of diluted fuel-air mixtures (lean mixtures, recycled exhaust gas).

Inventor: TSUJIMOTO TAKEO
IPC: A01C1/00
Filed: 1995-05-30
Abstract: The present invention consists in a method of improving germination of seeds which comprises adding the seeds to a solid-form superabsorbent polymer that has absorbed water, and treating the seeds for control-led hydration for a time and at a temperature suffi-cient to cause the seeds to imbibe sufficient water to enhance resultant plant vigor but insufficient to cause seeds sprouting, while supplying an oxygen-containing gas to the seed-medium mixture.  In accordance with the present invention, solid medium particles will not remain adhering to the seeds, the seeds after hydration treatment can be dried with ease and, therefore, improved seeds capable of rapidly and uniformly germi-nating can be produced at low costs and on a commercial scale, without damaging the seeds.

Title: Medium access control protocol for wireless network
Inventor: FISCHER MICHAEL A
IPC: H04L12/28
Filed: 1994-01-27
Abstract: A communicator station wirelessly transmits frames to and receives frames from a least one additional communicator in a Group in accordance with a MAC protocol. One of the communicators functions as a hub and the remaining communicators function as remotes. The hub sends control information to the hubs to establish repeating communication cycles, each of which has intervals during which the hub and the remotes transmit and receive frames. The intervals allow the hub and the remotes to anticipate transmitting and receiving frames, thereby allowing the remotes to power off their receivers and transmitters to achieve a considerable savings in power consumption without degrading communications. Other improved features include adjusting the intervals and the durations of transmission opportunities in the communication cycle to obtain the beneficial aspects of TDMA and PRMA for LAN-like communication without also incurring most of the undesirable aspects of such MAC techniques. Other control functions such as arbitration determine which communicator is better suited to act as the hub.

Patent CA-2156773-A1 (CA)
Inventor: WEISS HEINZ
IPC: B60W30/18
Filed: 1995-08-23
Abstract: A method is described for controlling the power train of a work vehicle.  The power train includes an engine with a fuel injection control and an infinitely variable transmission.  The method include first determining an initial engine speed, an initial wheel speed, the actual engine speed, and the actual wheel speed.  To improve comfort and reduce fuel consumption and emissions two steps are performed. First, the transmission ratio of the infinitely variable transmission will be increased if the actual engine speed is less than the initial engine speed, or decreased if the actual engine speed is greater than the initial engine speed. Second, while the transmission ratio remains constant, the engine speed will be adjusted until the engine speed is the same as the initial engine speed.
