Abstract: In the case of forming a plurality of rows of modified regions, in the thickness direction of a processing object, along a line to be cut, a first modified region closest to a first surface and a second modified region closest to a second surface are accurately formed. In a laser processing method, laser beams are applied by having a light collecting point inside the processing object (1), and the modified regions (M1-M6) to be starting points of cutting are formed, in the thickness direction of the processing object (1), along the line (5) to be cut on the processing object (1). Among the modified regions (M1-M6), the modified region (M6) closest to a rear surface (21) is formed by having the position of the rear surface (21) as reference, and the modified region (M1) closest to the front surface (11a) is formed by having the position of the front surface (11a) as reference. Thus, even when the thickness of the processing object (1) varies, shift of the position of the modified region (M6) and that of the position of the modified region (M1) due to changes of the thickness of the processing object (1) are suppressed.

Abstract: A very small loop antenna element of an antenna apparatus includes a plurality of loop antenna parts that each have a predetermined loop plane and radiate a first polarization component parallel to the loop plane; and at least one connecting conductor that is oriented orthogonally to the loop plane, connects the plurality of loop antenna parts and that radiates a second polarization component orthogonal to the first polarization component. It is arranged that the maximum value of the antenna gain of the first polarization component be substantially the same as the maximum value of the antenna gain of the second polarization component when the distance between the antenna apparatus and a conductive plate is changed in a case where the antenna apparatus is disposed close to the conductive plate. Because of this arrangement, the composition of the first and second polarization components is substantially constant regardless of that distance.

Title: Reducing fast ions in a plasma radiation source having a second activation source
Inventor: IVANOV VLADIMIR VITALEVITCH
IPC: G03F7/20
Filed: 2007-12-19
Abstract: Reducing Fast Ions in a Plasma Radiation Source A radiation source with an anode and a cathode to create a discharge in a discharge space between the anode and the cathode is disclosed. A plasma is formed in the radiation source which generates electromagnetic radiation, such as EUV radiation. The radiation source includes a first activation source to direct a first energy pulse onto a first spot in the radiation source near the discharge space to create a main plasma channel which triggers the discharge. The radiation source also has a second activation source to direct a second energy pulse onto a second spot in the radiation source near the discharge space to create an additional plasma channel. By directing the second energy pulse during the same discharge, a shortcutting of the main plasma current is realized which in turn may reduce the amount of fast ions produced. ® KIPO & WIPO 2009

Title: Process for selective aromatics disproportionation with increased conversion
Inventor: BOLDINGH EDWIN P
IPC: C07C15/08
Filed: 2007-05-05
Abstract: An improved process is disclosed for the selective disproportionation of toluene. The process preferably uses a disproportionation catalyst comprising a pentasil type zeolite such as MFI that is bound with aluminum-phosphate. Running the process at a toluene conversion greater than 30 wt-% and at a hydrogen-to-hydrocarbon ratio less than 3.0, and especially a ratio of 0.1 to 1.0, improves the maximum yield of para-xylene. Periodic rejuvenation by increasing the hydrogen-to-hydrocarbon ratio removes some carbon deposits and restores catalyst activity. An inert diluent gas assists in selective pre-coking of the catalyst as well.
