Title: Preparation of novel high temperature resistant aromatic phosphate flame retardants
Inventor: SU WEN-JIUNG
IPC: C07F9/145
Filed: 1999-06-15
Granted: 2001-10-11
Abstract: This invention describes the preparation of novel high temperature resistant aromatic phosphate flame retardants. The principle of molecular design is utilized to simplify synthesis procedures and refine purification conditions to prepare same series of the aromatic phosphate compounds. 10-chloro-9, 10-dihydro-9-oxo-10-phosphine (CDDP) intermediate is obtained from two-step heating esterification and cyclization of trichloro phosphide and equivalent amount of ortho-benzyl phenol in the presence of small amount of zinc chloride catalyst. Dihydroxybenzene or trihydroxybenzene aromatic compounds are then added using organic bases as acid inhibitor or under direct heat to proceed the second step esterification to form aromatic phosphate products. The re-crystallization purification step is carried out under controlled temperature, solvent and concentration by using hydrogen peroxide for oxidation. Due to the high purity and steric structure effect, the final products exhibit good heat resistance and stability.

Abstract: Adjusting the phase angle of the phase shift mask is used to correct the phase angle error for the phase shift mask. Phase shift mask has an acceptable transmittance error. The method includes the following steps: provides a solution, sets the temperature and concentration of solution, dips phase shift mask in solution to produce a phase angle time change rate and a time change rate of transmittance, adjusts the phase angle error, and confirms that the change of transmittance falls within the acceptable range of transmittance error. Therefore, this invention allows phase angle adjustment after the phase shift mask is produced in order to save production cost.

Title: Pseudo lock detection system
Inventor: YOSHIE KAZUAKI
IPC: H04L27/227
Filed: 2000-03-15
Granted: 2001-11-01
Abstract: The present invention provides a pseudo lock detection system that is used to detect and avoid the pseudo lock for the carrier regenerating-loop. When a carrier reproduction in a demodulator 6 loop is detected to be locked and that frame synchronization cannot be established in data output from the demodulator 6, a detection signal c representing the occurrence of a pseudo locked state is output. In accordance with the detection signal c, the timer 22 is activated to count up. When the timer 22 reaches a predetermined value, an address counter 23 is made to count up, and compensation data in accordance with the address signal is read from a correction data memory 24. The compensation data is added up with channel selection data and is then input to a programmable divider 15, in which a local oscillation frequency is subjected to fine adjustment. Thus, the address signal remains updated until the pseudo locked state is released.

Title: Apparatus and method for texture analysis on semiconductor wafers
Inventor: KURTZ DAVID S
IPC: G01N23/20
Filed: 2000-08-09
Granted: 2002-02-21
Abstract: An apparatus and method for performing rapid, high-resolution polycrystalline crystallographic texture analysis, by calculating an orientaion distribution function (ODF) from partial pole figures obtained from x-ray diffraction measurements on large samples, e.g., 200 millimeter diameter wafers. The measurement apparatus includes a 2-D area x-ray detector and a collimated x-ray source arranged in a specific, fixed spatial relationship dependant on the properties of the sample to be measured, and also includes a particular wafer motion assembly. The wafer motion assembly includes three mutually orthogonal rectilinear translation stages, and a φ rotation stage mounted thereon, as an uppermost motion stage, with its range restricted to 180 DEG of rotation. θ-2θ and χ motions are eliminated, and the close deployment of the x-ray source and area detector to the measuring spot on the wafer is such that the detector covers a sufficient range of 2θ and χ to capture multiple diffraction arcs in each frame. The invention employs a new and advantageous texture analysis protocol to determine ODF from the severely truncated pole figures thus obtained, through comparison of experimental ODF figures with calculated ones. The resulting system is fast, accurate, amenable to automation, and does not require highly skilled personnel to operate.
