Title: Oscillator controller with first and second voltage reference
Inventor: HALAMIK JOSEF
IPC: H03K4/06
Filed: 2000-12-05
Granted: 2002-09-01
Abstract: A controller oscillator provides a periodic output signal having first and second output level states. The oscillator is responsive to an applied saw tooth signal that varies between first and second voltages (Vlow, Vhigh). The oscillator is comprised of a comparator (82) the noninverting input of which receives the saw tooth signal applied thereto to produce the periodic output signal at its output (86). A first voltage reference circuit (88, 90, and 92) generates the second voltage (Vhigh) that is applied to the inverting input of the comparator while the periodic output signal is at the first output level state and the input signal charges from the first voltage (Vlow) towards the second voltage. As the input signal becomes equal to the second voltage the output of the comparator switches to the second output level state and a second voltage reference (92, 94, 96) provides the first voltage at the inverting input of the comparator.

Title: Method for fast calculating the square root of integers
Inventor: CHEN HUAI-YAN
IPC: G06F1/00
Filed: 2000-12-20
Granted: 2003-08-21
Abstract: The present invention provides a method for fast calculating the square root of integers, which is to add 0.5 to a series of integers. After conducting squaring, the series formed by the integers after squaring has the characteristic of two-stage equal-distance series. With this characteristic, in an electronic product, there is established an index table formed by a series of integer progression of the squared numbers within the maximum range for the required square root in the program for conducting squaring operation. Thus, when the electronic product is conducting the squaring operation on the inputted squared number, it can look up the index table to ensure the trying starting number and the series increments, and use the exhausted cyclic operation method to calculate the integer most close to the square root through a small amount of adding operation.

In addition, the thermal insulative performance will not be deteriorated due to the increasing of the solid thermal conductivity. Therefore, even a large amount of vacuum thermal insulative material is used, the quality of the thermal insulative box will not be adversely affected, and the energy-saving purpose can be achieved by the excellent thermal insulative performance. In addition, the recycling method of this invention can regenerate industrially rigid polyurethane foam that is used as a raw material of a tolylenediisocyanate composition of the thermal insulative material and become a raw material for rigid polyurethane foam.
