Title: Benzanthrone polymerization gate in photopolymerizable compositions
Inventor: SYPEK MARIA T
IPC: G03F7/021
Filed: 1996-02-20
Abstract: A light sensitive composition which is capable of photopolymerization which includes a photopolymerizable compound a free radical generating component and a benzanthrone or substituted benzanthrone which substantially prevents photopolymerization when the light sensitive composition is exposed to actinic radiation below a threshold amount but permits photopolymerization when the light sensitive composition is exposed to actinic radiation above a threshold amount.  This achieves a gate effect which eliminates or decreases unwanted partial exposure in the nonimage areas and hence improves reproduction quality.

Abstract: A heat exchanger and heat pump circuit having an operating subcircuit and a pump down subcircuit each including a liquid line and a heat transfer tube. The heat transfer tube of the pump down subcircuit surrounds the liquid line of the operating subcircuit. During the heating cycle, the heat pump circuit circulates refrigerant through both subcircuits to abstract heat from the heat source/sink. However, during the cooling cycle, the heat pump circuit circulates refrigerant only through the operating subcircuit. Also during the cooling cycle, the heat pump circuit places the pump down subcircuit at low pressure to thermally insulate the operating subcircuit liquid line.

Title: Method for manufacturing a pyroelectric mixture
Inventor: DULTZ WOLFGANG
IPC: H01L37/02
Filed: 1996-12-20
Abstract: The present invention relates to a method for manufacturing a pyroelectric mixture, in particular for pyroelectric and piezoelectric elements.  The method that is used to do this includes the following steps: mixing at least two compounds in a predetermined mixing ratio, one compound containing a polymerizable, preferably achiral, liquid crystalline monomer, the other compound being advantageously an achiral liquid crystal polymer or copolymer. Each compound contains substituents that form hydrogen bridges. The mixture is heated above the specific glass point. Next, an electrical field is applied, with the help of which the polymerizable monomer polymerizes and the mixture is poled. With the electrical field applied, the mixture is cooled below the glass point. The pyroelectric coefficient of the mixture that can be achieved lies in the order of magnitude of pyroelectric elements of the PVDF type. Its quality factor is, however, higher than that of the known elements of the PVDF type.

Inventor: CORVIN JOHN H
IPC: B60T8/36
Filed: 1997-04-17
Abstract: A pulse width modulated drive circuit drives a solenoid operated valve in response to an input voltage signal from a control apparatus.  The solenoid operated valve includes a coil that is energizable in response to energy received from the pulse width modulated drive circuit.  The pulse width modulated drive circuit includes a pulse generator stage and an output stage.  The pulse generator stage receives the input voltage signal from the control apparatus and a feedback signal from the coil which ultimately combine to form a control voltage in response to which the pulse generator stage generates a pulse width modulated signal whose duty cycle depends on the control voltage.   The output stage receives the pulse width modulated signal from the pulse generator stage and generates in response thereto a pulse width modulated output signal across the coil.  The pulse width modulated output signal has pulse width generally proportional to the control voltage and carries energy from a source of energy.  The pulse width modulated output signal energizes the coil thereby enabling the coil to generate a force generally proportional to the average current carried by the pulse width modulated output signal.
