Process for preparing optically active compounds

This document describes a novel and practically excellent process for the preparation of optically active compounds, such as optically active alcohols or amines which are useful for various applications, for example, as synthetic intermediates of pharmaceuticals, liquid crystal materials, and reagents for optical resolution, wherein a hydrogen transfer type asymmetric reduction is carried out in the presence of both a transition metal complex and an optically active nitrogen compound or a transition metal complex having an optically active nitrogen compounds as an asymmetric ligand, and a hydrogen-donating organic or inorganic compound.

A medical staple formed from a nitinol wire, the staple having two elongated arms which extend upwardly and outwardly from a central loop in two opposing generally semicircular courses forming an arc extending upwardly and outwardly and an end second comprising a sharpened endpoint, the endpoint being the arms bendable under resistance, is disclosed. In some embodiments the arms extend upwardly on a parallel course and then outwardly. The material is preferably an alloy with hyperelastic characteristics. The staples are placed in a flexible endoscope and a lumen catheter within the endoscope, using a hook or forceps in the lumen catheter having a distal end in the lumen of the catheter and the staple distal to the forceps in folded configuration with the arms folded inward in the lumen catheter, positioning the distal end of the lumen catheter at a location in the patient's gastrointestinal tract where stapling is desired, moving the forceps distally so as to force the staple forward out of the lumen catheter and cause the end points to pierce the patient's inner wall of the gastrointestinal tract.

Gait Pattern Generating Device and Controller of Legged Mobile Robot

A gait generating system of a legged mobile robot is provided with a device for determining a desired trajectory of an external force to be applied to a robot 1, a device for determining a parameter of a desired gait (current time gait) for a predetermined period on the basis of a desired trajectory of an external force or the like, a device for determining a parameter of a virtual cyclic gait that follows the current time gait on the basis of the desired trajectory of the external force or the like, a device for correcting the current time gait parameter such that a body motion trajectory of the robot 1 of the current time gait converges to a body motion trajectory of the cyclic gait, and a device for sequentially determining an instantaneous value of the current time gait on the basis of the corrected current time gait parameter. With this arrangement, in an environment wherein an external force acts on a robot as necessary, a desired gait that allows continual stability of the robot to be secured can be generated even if the external force suddenly changes.

Gas engine electric power generating system effectively utilizing greenhouse gas emission credit

The gas engine electric power generating system in which the electric power generating apparatus composed of an electric power generator connected with a gas engine of a pilot fuel oil ignition type is installed near a coal mine and the recovered methane gas and ventilated methane gas taken out of the mine shaft are introduced into the cylinder of the gas engine while being adjusted to be introduced as a lean methane/air mixture to operate the engine to produce electric power, is established near coal mine in developing country including China, the carbon dioxide emission credit produced by the difference in greenhouse effect index between the case where coal mine methane gas is released to the atmosphere and where said methane gas is utilized by the gas engine electric power generating system to be released to the atmosphere as carbon dioxide, is registered on a emission credit market to be traded with credit surcharge payment obligators(or those who want to purchase the emission credit). The invention also includes the affiliated system of mutual patronage relation constituted by one or a plurality of the systems and nearby power generating system or systems using coal bed methane or pre-mining gas as fuel.

Locally confined photodynamic treatment for diseased tissue

A pharmaceutical composition, method and apparatus for treatment, diagnosis or both treatment and treatment of hyperproliferative malignant and non-malignant diseases of epithelial tissues is disclosed. The invention comprises local application of the pharmaceutical composition to a predetermined area of the tissue characterized by complete and consistent coverage of the tissue, including irregularly shaped tissue. The pharmaceutical composition consists of an active component, such as a photosensitizer or a precursor thereof, and at least one carrier substance including a viscous fluid, a gel, or a fluid that becomes viscous upon contact with the tissue. The gel's viscosity allows it to adhere to the tissue for a sufficient amount of time to transfer the photosensitizer or precursor. In a preferred embodiment the pharmaceutical composition is sprayed onto the surface of the diseased tissue. Optionally, a mechanical device is used to further restrict the composition to a specific areas and can also be used to press the composition onto the tissue. In another embodiment, components of the composition are delivered to and mixed at the treatment site by a suitable delivery device prior to irradiation. The active component is then activated by a suitable wavelength of radiation.
