Title: Temperature sensor control circuit for microwave ranges
Inventor: RYU WOOK-YOL
IPC: H05B6/68

Granted: 1990-04-04
Abstract: A disconnection state of a temperature sensor (TH2) is checked by a sensor checking resistor (RC) at which an A/D input value shows to infinity for a disconnection state.  A setting temperature is determined by selection of a temperature reference resistor (Rf) value, i.e. the heating temperature regulates to the value of Rf so that the correction of the program is not necessary even when the application of the sensor is different.  In normal case, the A/D input value is determined by the difference between the resistance values of the sensor and the reference resistor so that the real temperature is measured.'

Title: Piezoelectric copolymers of vinylidene fluoride
Inventor: PATRICK KAPPLER
IPC: H01L41/18
Filed: 1988-12-08
Granted: 1995-08-10
Abstract: Copolymer of vinylidene fluoride and of trifluoroethylene having at the same time piezoelectric properties and a maximum use temperature which are both high, in which the overall molar content of trifluoroethylene is lower than 30%, characterised in that it has a heterogeneous structure, its cumulative molar composition distribution curve being included between two straight lines:
 Y = -3.18 X + 140
 and Y = 3.12 X + 109
 X being the molar percentage of trifluoroethylene in the macromolecular chains and Y being the weight percentage of all the macromolecular chains whose trifluoroethylene content is higher than or equal to X. This copolymer is obtained by copolymerisation in aqueous suspension by reaction, in a first step, of a mixture of vinylidene fluoride and of trifluoroethylene in molar proportions of vinylidene fluoride of between 67 and 54% to 33 to 46% of trifluoroethylene and, in a second step, by progressive addition of vinylidene fluoride to the reaction mixture in proportions such that the molar quantity of added vinylidene fluoride represents 145 to 180% of the number of moles of initial vinylidene fluoride.

Title: Tire simulating method
Inventor: BLINN ROBERT JOHN
IPC: B60C11/03
Filed: 1989-02-22
Granted: 1998-08-17
Abstract: A method is disclosed for evaluating the level of objectionable noise associated with the operation of a tire by virtue of its tread contacting a road surface, which comprises digitizing the tread design on a coordinate system so as to define load-supporting portions of the tread in contact with the pavement, and distinguish them in binary form from those portions of the tread which are not in contact, as multiple matrix elements; defining a generally arcuate profile of a leading or trailing edge of a footprint of the tread by fitting an equation to the edge; sequentially performing the time ensemble summation, of the noise produced by each matrix element, over every matrix element on the entire circumferential surface; converting the sequence of summation to a periodic analog signal; converting the analog signal to a sound; and aurally evaluating the sound. In a simplified case 0's and 1's along at least one footprint edge are sequentially summed around the circumference of the tire. The system requires only a means for digitizing the tread pattern, a computer to perform the necessary manipulations of data, and a means to convert a digital signal to an analog signal. Having subjectively chosen a tread pattern deemed to have an acceptable noise level, ribs are then relatively rotated one with respect to another to obtain an improved level of tread noise.
