Granted: 2012-10-09
Abstract: A high-density optical disc such as BD-ROM (Blu-ray Disc ROM) or BD-R (Blu-ray Disc Recordable) having a function for preventing unauthorized duplication of data written therein, and a method for restricting playback of illegally duplicated optical discs are disclosed. In accordance with the invention, the optical disc is additionally recorded with disc identification information, adapted to identify the kind of the optical disc, in the form of physical marks, on a particular area thereof. The method of the invention includes the steps of detecting and identifying disc identification information from an optical disc at an initial stage of a servo operation carried out by an optical disc apparatus adapted to play back the optical disc, while identifying the format of data read out from the optical disc, thereby determining whether or not the read-out data was illegally duplicated on the optical disc, and forcibly restricting a data reproduction operation of the optical disc apparatus, based on the result of the determination. Accordingly, it is possible to efficiently prevent unauthorized duplication of data, recorded on a high-density optical disc such as BD-ROM, onto BD-RE or BD-R, while efficiently preventing reproduction of the illegally duplicated data.

Granted: 2012-06-26
Abstract: L'invention concerne une extrémité de canette comprenant un bourrelet conique (25), une paroi tendue inclinée (24) ainsi qu'un serti résistant. Cette extrémité de canette résiste aux distorsions de son profil circulaire lors d'un traitement thermique ou du conditionnement de boissons gazeuses. Cette résistance circonférentielle élevée influe sur la manière dont l'extrémité de canette cède finalement lorsqu'elle est soumise à des conditions de déformation extrêmes, même si ses performances en pression de flambage correspondent aux normes industrielles spécifiées. L'extrémité de canette selon l'invention présente des caractéristiques de régulation qui servent à réguler le mode de déformation tout en maintenant les performances en pression de flambage spécifiées. Dans un mode de réalisation de l'invention, ces caractéristiques de régulation comprennent l'expansion du bourrelet conique qui peut servir à déclencher un flambage <= positif >= local, ainsi qu'une rainure ménagée dans la paroi tendue qui sert à empêcher la force de flambage <= positif >= de se concentrer en un point unique, et ainsi éviter toute fuite due à l'apparition d'une piqûre.

Patent CA-2513990-C (CA)
Inventor: ARSENAULT PAUL JACOB
IPC: G01N23/04
Filed: 2005-07-27
Granted: 2010-09-14
Abstract: The present invention pertains to a method and an apparatus to generate a density image of an object using fan or cone beams of radiation and collimated detectors on one side of the object. The method consists of irradiating an object with a plurality of pairs of non-parallel radiation beams wherein the beams in each pair intersect a same segment along the axis of the detector. Compton-scattering radiation from the beams are then measured, and corrected attenuation coefficients along each beam are obtained. This latter step is effected by taking a first ratio of detector measurements for the beams in each pair; comparing the first ratio with a second ratio of corresponding calculated detector measurements and balancing discrepancies between the first and second ratios in a forward-inverse numerical analysis algorithm. Taking ratios of attenuation coefficients along related incident beams eliminates non-linearity problems whereby the aforesaid algorithm can be solved.

Granted: 2011-11-29
Abstract: An information radio transmission system is provided that enables provision of correct control information on the transmitting side irrespective of the error volume when an error occurs in communication data. Error volume measuring data string storage units that store an error volume measuring data string are provided in both a transmitting-side communication device that transmits data by radio transmission and a receiving-side communication device that receives data transmitted from the transmitting-side communication device. The receiving-side communication device has an error volume measuring unit that measures the error volume when transmitting data. An error volume measuring data string is added to data and the data is transmitted from the transmitting-side communication device. Having received this, in the receiving-side communication device, the error volume measuring unit compares the error volume measuring data transmitted from the transmitting-side communication device with an error volume measuring data string stored in an error volume measuring data string storage unit of the receiving-side communication device, thereby measuring the error volume.

Title: Rockbolts made of high-strength steel pipes and method of manufacturing thereof
Inventor: NAKAKO TAKEFUMI
IPC: E21D20/00
Filed: 2004-07-29
Granted: 2010-11-02
Abstract: A high-strength steel pipe rockbolt has an expansive rockbolt main body prepared by processing a high-strength steel sheet of 1.8-2.3 mm in thickness with tensile strength of 490-640 N/mm2 and elongation of 20% or more to a welded pipe and roll-forming the welded pipe to a shaped pipe having one or more concavities extending along an axial direction. Use of the high-strength steel sheet ensures sufficient strength of the shaped pipe regardless of a decrease in thickness. The thin welded pipe is also advantageous in resistance to cracking caused by accumulation of strains introduced during roll-forming, swaging both ends of the welded pipe and hydraulic expansion. Moreover, expansive deformation of the shaped pipe is initiated by injection of a pressurized fluid at a low pressure, so that the expansive deformation is completed in a short time period with an improved working efficiency.
