Title: Method of forming conductive paths on a substrate having depressions
Inventor: RICHTER HORST
IPC: H01L27/15
Filed: 1995-12-22
Abstract: The invention concerns a method of forming a number of electric conductors at a very short distance from the end of depressions such as V-grooves on a substrate.  In one configuration example, a film of PTFE or of a similar material is laminated over the entire surface of the substrate.  Holes are etched in the film.  The holes are metallized.  Conductive paths are formed, which are electrically connected to the metallized holes.  The film in the area of the grooves is removed by etching.  In another configuration example, the grooves are temporarily filled with a photoresist and the conductive paths and contact surfaces or bumps are formed in accordance with a photolithographic method.

Title: Piston-based ventilator design and operation
Inventor: YOUNES MAGDY
IPC: A61M16/00
Filed: 1992-02-12
Abstract: Improvements in piston-based ventilator design and operation are described.  An individual compensation of force dissipation within the gas delivery system is effected, so that the desired gas pressure is delivered to the patient airway without the necessity for monitoring the actual pressure and using it as feedback. A piston is dimensioned slightly less than the chamber wall of the pump to define a gap through which an acceptable amount of gas may leak but which eliminates the need for a physical seal, thereby minimizing the frictional resistance within the pump.
Patent CA-2168676-A1 (CA)
Inventor: NAKANISHI MAKOTO
IPC: G01R31/40
Filed: 1996-02-02
Abstract: A failure detection system for detecting a failure in a power converter includes: a by-pass switch for switching the electric power supply so that electric power is supplied from a standby power source to a load instead of from a power converter; a switch operation circuit for turning on and off the by-pass switch; a first current detector for detecting the inverter output current of the power converter, a second current detector for detecting the load current flowing through the load; an operational amplifier for adding the outputs of the first and second current detectors; and a comparator for detecting a failure of the by-pass switch, wherein if the addition result given by the operational amplifier is less than a predetermined value when the switch operation circuit is turned off, the comparator concludes that the by-pass switch has a failure.   In this failure detection system, it is possible to detect a failure of the by-pass switch used to transfer the electric power to the load from the standby power source in stead of from the power converter, without having to detect the current flowing through the by-pass switch. Thus it is possible to reduce the size and the cost of the system.

Title: Biologically Relevant Methods for the Rapid Determination of Sterility
Inventor: BURNHAM JEFFREY C
IPC: C12M1/40
Filed: 1994-09-26
Abstract: The invention is directed to biological processes and apparatus for determining the efficacy of a sterilization cycle based upon the recovery of activity of interactive enzyme systems comprising enzymes, coenzymes, catalysts, cofactors, substrates or any other necessary reagents. The invention provides a vital process for expediting sterility verification before utilization of the articles thought to be sterilized. The invention involves the rapid detection of any surviving interactive enzymatic activity which directly relates to the probability of any biological spores surviving in a test sample. An absence of a change indicates that the sterilization process had inactivated the enzyme system thereby preventing the interactive reaction from taking place which is a rapid equivalent to directly detecting the survivability of bacterial spores in a similar test. The methods and apparatus of the invention are useful in the health care industry such as in hospitals, laboratories, and research institutions, in food and environmental technology, and in all technologies which utilize sterilization in manufacturing, production or waste disposal.

Inventor: YONEMURA SHUICHI
IPC: B60T8/34
Filed: 1996-12-24
Abstract: A brake control apparatus for a vehicle employs a pressure-amplifying device which reduces a quantity of brake fluid generating a  first brake-fluid pressure in a  first conduit connected to a master cylinder, and increases second brake-fluid pressure in a second conduit, applied to a wheel cylinder  simultaneously with the  reduction in brake-fluid quantity in the first conduit. As a result, increase in the first brake-fluid pressure is suppressed even when a driver depress  a  brake  pedal  and  load  to  generate  the  first brake-fluid  pressure  is  alleviated.    Additionally,  the pressure-amplifying  device  applies  the  increased  second brake-fluid pressure to the wheel cylinder.  Therefore, it is possible to ensure sufficient braking force.

Abstract: A host central processing unit (CPU) of a portable computer executes a software driver, which performs the functions of most of all of the components of a modem.  When the portable computer is connected to an analog communication device, analog components mounted on the main circuit board of the portable computer convert data between a form used by the computer and a form that is suitable for transmission and reception by the communication device.  On the other hand, when the portable computer is connected to a digitalcommunication device, these analog components are unused and remain powered-down.  Alternatively, a portable computer that is to be connected to only digital communication device omits the analog components altogether.
