Title: Method for manufacturing ceramic-based composite material
Inventor: YOSHIDA TAKASHI
IPC: C04B35/80
Filed: 2000-02-25
Granted: 2007-06-12
Abstract: A matrix formation process 10 is configured with CVI process 12 and PIP process 14, 15, 16 in which a co-polymer containing at least polycarboxysilane (PCS) and polymethylsilane (PMS) is applied. Crosslinking of each polymer is performed at an intermediate temperature which is lower than the pyrolysis temperature of the polymeres. Polymer impregnation process 15 for infiltrating the co-polymer into a matrix, and inert gas firing process 16 for firing the material at a high temperature in an inert gas atmosphere. In the crosslink process, the mixed polymer is held at about 573K to 723K for a predetermined time. The conversion ratio of the co-polymer crosslinked into SiC in the subsequent firing process is increased, efficiency of filling SiC in the PIP process is increased, and an airtight ceramic-based composite material can be manufactured efficiently within a short time.

Abstract: The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.

Abstract: Two pieces of semiconductor wafers 10 1 and 10 2 to be stacked and fused together are secured to wafer holders 20 1 and 20 2 respectively, and are then integrally held at a wafer hold unit 2. Rough position alignment is first applied to these semiconductor wafers 10 1 and 10 2 while supplying infrared light thereto from an infrared light source 30 of an infrared light system 3 for detection of a resultant lattice image at a detection unit 5. Then, fine position alignment is performed while supplying laser light from an laser light source 40 of a laser light system 4 for detection of a resultant diffraction image at the detection unit 5. Thus, in the manufacture of a semiconductor device having its crystal structure with three-dimensional periodical refractive index distribution employing precision multilayer stack methods by using a wafer fusion, a method and apparatus for manufacturing the semiconductor device is realized which is capable of achieving precise position alignment between lattice layers stacked over each other with reduced complexity in position alignment thereof.

Abstract: The twine cutter for a bale processor comprises a blade holder has a front end and a back end, the holder further has a top edge that is bevelled to a wedge shape at the front end, a back edge and a base edge. A drive mechanism such as an elongated handle is fixed to the holder for driving the holder back or forth. A cutter blade is fixed to the holder such that a cutting edge is bevelled towards the front of the holder and a further cutting edge is bevelled towards the back of the holder thereby being able to cut twine when the holder is driven forward or backward. The cutter blade may further include a sharpened hook shaped section used to snag and cut twine. The hook shaped section can be positioned at the apex of the triangular upper portion of the single blade. A disintegrator roller for a bale processor comprises an elongated roller arranged to rotate in one direction about its axis with a number of flails intermittently spaced along the length and around the circumference of the roller. Each of the fails are mounted within a support that is fixed to the surface of the roller such that the flails pivot freely in a plane in their direction of rotation.  The roller further includes a bar fixed to the surface of the roller and to the supports facing the direction of rotation of the roller. Support gussets may also be positioned between the supports and are fixed to the bar and the roller. The bars and the gussets are typically welded in place. The roller may also include bumpers for preventing the back of the flails from contacting the roller.

Abstract: Crystals of P1-(2'-deoxycytidine 5'-) P4-(uridine 5'-) tetraphosphate (dCP4U ) or salts thereof; a process for the production of the crystals; and a proces s for the preparation of dCP4U by reacting uridine 5'-monophosphate (UMP) with 2'-deoxycytidine 5'-monophosphate (dCMP), diphenylphosphoro-chloridate (DPC) and a pyrophospate (PPi). The crystals of dCP4U have a high purity and are easily handleable by virtue of their lower hygroscopicity and higher stabili ty than those of the products of freeze drying, thus being useful as the raw material of drugs. The process for the preparation of dCP4U permits the production of dCP4U by the use of inexpensive UMP as the starting material i n a high yield, thus being suitable for mass production of dCP4U.

Abstract: L'invention concerne un système de traitement qui décode des informations de programmes en paquets, notamment des informations auxiliaires spécifiques à des programmes, comportant plusieurs tables d'informations classées dans un ordre hiérarchique. Les informations auxiliaires sont utilisées pour acquérir et décoder les informations de programmes en paquets, de manière à fournir un programme vidéo à afficher. Le système de traitement utilise un procédé qui comprend la détection d'une différence entre un numéro de version d'une première table d'informations spécifiques aux programmes (par exemple, une table de canal virtuel (VCT), ou une table d'informations de canal (CIT)) et un numéro de version correspondant de la première table transmis dans une seconde table (par exemple, une table de guide principal (MGT)). Si une différence est repérée, les première et seconde tables contiennent forcément un numéro de version compatible de la première table. Les informations de programmes en paquets sont décodées afin de fournir un programme vidéo à afficher qui utilise les informations spécifiques aux programmes, comprenant la première et la seconde tables, comportant elles-mêmes le numéro de version compatible obligatoire. Une différence repérée peut aussi être ignorée afin de permettre le décodage des informations de programmes en paquets et une gamme de canaux d'utilisateur peut être montée, afin d'enlever les canaux associés à une différence repérée ou à une autre condition d'erreur, contenue dans les informations spécifiques aux programmes.
