Title: Plasma processing apparatus and processing method
Inventor: ITO YOUBUN
IPC: H05H1/46
Filed: 2001-05-28
Granted: 2002-07-21
Abstract: In order to form a magnetic field around a processing space, in the plasma processing apparatus of this invention, an annular segment magnet is rotated around and above a processing chamber, in a circumferential direction of the processing chamber, by means of a rotating mechanism. A magnetic field is formed around the processing chamber by means of a magnetic field-forming mechanism. It is at a substantially no-magnetic state at the position of a substrate to be processed, thereby preventing the charge-up damage. The magnetic field has a plasma-sealing effect so that the plasma processing rates at the peripheral portion and the central portion of the substrate are the same, thereby resulting in uniform processing rate. Each of the magnets of the magnetic field-forming mechanism consists of two parts, the distance between which can be changed by means of a rotating device, thereby varying the magnetization direction.

Granted: 2002-06-11
Abstract: The method provides designs parameter for point angle of an optimum drill bit (double blades, 30 degree helix angle and 8-12 degree back bevel angle) for drilling magnesium alloy. Using the design of point angle to perform drilling operation on magnesium alloy improves quality of drilling result of magnesium alloy, including reducing twin-crystal structure of the magnesium alloy caused by deformation force resulting from drilling operation on the workpiece, alleviating reduction of fatigue life of the magnesium alloy caused by drilling operation, and enhancing reliability of drilling products. The twin-crystal structure of the drilling workpiece can be significantly suppressed and a smooth machining surface of the drilling workpiece can be obtained if a cutting lubricant of sodium hydroxide solution of predetermined percentage is used in the drilling operation.

Title: Infrared evaluation of the stoichiometric ratio of dihydric phenol to diarylcarbonate during production of polycarbonates
Inventor: MCCLOSKEY PATRICK JOSEPH
IPC: G01N21/35
Filed: 2001-06-22
Granted: 2004-01-21
Abstract: The stoichiometric ratio of dihydric phenol to diarylcarbonate during production of polycarbonates can be evaluated by infrared analysis, preferably using an FTIR spectrometer, to detect the amount of BPA or other dihydric phenol in the mix tank. In one format of the method, one or both of two characteristic peaks, reflecting the methyl CH bonds and hydroxyl OH bonds are evaluated. These peaks occur equally in BPA monomers and oligomers, and hence are independent of the degree of oligomerization or polymerization which has occurred. For this reason, monitoring of stoichiometry can be performed on the contents of the mix tank, or on the products from or contents of any downstream reactors. Using a calibration curve, the absorbance associated with these bonds is converted into a measure of the concentration of BPA and from that to first moles and then grams of BPA in the mixture being tested. The amount of DPC is determined by subtracting the number of grams of BPA from the total initial sample weight. In another format, a ratio of the size of the peaks associated with DPC carbonyl and BPA methyl is used directly to determine the ratio of DPC to BPA.

Title: Silicon single crystal wafer and method for manufacturing the same
Inventor: SAKURADA MASAHIRO
IPC: C30B15/00
Filed: 2001-06-29
Granted: 2003-03-01
Abstract: This invention provides a silicon single crystal wafer grown by the CZ (Czchralski) method, having a diameter of 200 mm or more, and manufactured from a single crystal grown at a growth rate of 0.5 mm/min or more without doping it with anything other than the resistance-adjusting dopant. The wafer is free of grow-in defect such as octahedral void defects attributed to vacancy and dislocation clusters attributed to interstitial silicon. By the method, a silicon single crystal substantially free of growth defects such as octahedral void defects and dislocation clusters can be grown by the normal CZ method at a rate higher than conventional. The concentration of interstitial oxygen in the crystal can be controlled to a low level, thereby manufacturing a high-quality large-diameter silicon single crystal wafer having a small precipitation and an improved unevenness distribution of the BMDs in the wafer surface. A method for manufacturing such a silicon single crystal wafer is also disclosed.

Title: Apparatus and method for correcting holding position of component
Inventor: YAMAGUCHI MINORU
IPC: H05K13/08
Filed: 2001-07-23
Granted: 2002-09-21
Abstract: The present invention is capable of avoiding the occurrence of suction error caused by a deviation of a suction nozzle with respect to a component so as to prevent a falling accident when holding a component. In the invention, the deviation amount between the center position of a component 72 absorbed by a suction nozzle 21 and the suction position of the suction nozzle 21 is detected. In addition, a value obtained from multiplying this deviation value by a sensitivity coefficient is added as a position correction at next time when using the suction nozzle to conduct the suction operation. Thus, when using the suction nozzle 21 to absorb the component 72, the suction nozzle 21 normally absorbs the component 72 at the position substantially corresponding to the center of the component.

Title: Cam mechanism and door opening/closing mechanism
Inventor: YOSHIKAWA TAKASHI
IPC: E05D11/10
Filed: 2002-02-25
Granted: 2003-02-21
Abstract: A cam mechanism has different portions thereof arranged on a main unit 1 and on a door 2. When the door 2 is closed, a hinge pin 23 is locked at one end of a hinge groove 9, keeping the cam mechanism in a first locked position. As the door 2 is opened, the hinge pin 12 is guided by the hinge groove 9 and a guide pin 25 is guided by a guide groove 11, permitting the door 2 to rotate and slide. Thus, the hinge pin 23 is locked at the other end of the hinge groove 9, bringing the cam mechanism to a second locked position. A boss 10 slides on a rib 19 and thereby maintains the second locked position, permitting the door 2 to rotate about the hinge pin 23. This structure helps realize a door opening/closing mechanism with enhanced operability at reduced cost.
