Abstract: There are provided a method of producing an SOI wafer of high quality with excellent controllability, productivity and economy, and a wafer produced by such method.  In the method of producing a substrate by utilizing bonding of wafers, a first substrate member and a second substrate member are mutually bonded and then the second substrate member is separated from the first substrate member at the interface of a first layer and a second layer formed on the main surface of the first substrate member, whereby the second layer is transferred onto the second substrate member.  In the separation, the separation position at the interface of the first and the second layers is ensured by a method of varying the porosity of a porous Si layer, a method of forming an easily separable plane by the coagulation of pores in porous Si, a method of effecting ion implantation to the interface or a method of utilizing a heteroepitaxial interface.

Abstract: Apparatus is provided for self-righting a signpost after it has been tipped over comprising a plate for connecting to the signpost and a complementary tray secured to the ground. Most of the apparatus is located below ground out of harm's way. The tray has upturned peripheral edges within which the plate resides. A chain is connected to the plate, extends through a hole in the tray and into the bore of a pipe for connecting to the bottom of a compression spring. When the signpost and plate tip, the plate rotates within the tray, displacing the chain and compressing the spring. Preferably a lip extending over the edge of the plate causes the plate to ride up the edge of the tray, increasing the chain's displacement. The increased tension in the chain urges the plate and signpost to right themselves. The plate and tray are complementary and square shape so that the square sides engage during tipping and prevent rotation of the signpost's orientation when it returns to the upright position. Preferably a cup is mounted to the plate for insertion of the shaft of a conventional signpost.

Granted: 2002-12-24
Abstract: L'invention porte sur un appareil permettant de mesurer in situ le module de cisaillement d'une couche du sol (12) et comportant un pied (11) de contact, qui poussé par une force descendante présélectionnée, s'enfonce dans une zone donnée du sol. Alors qu'un transducteur (13) secoue le pied (11) verticalement, des capteurs (17, 18) mesurent la force qui lui est appliquée et ses déplacements en résultant, et émettent respectivement un premier et un second signal de sortie. Le signal de sortie émis en phase avec le déplacement est analysé en relation avec le signal de force ce qui permet la mesure d'un seul paramètre en fonction de la résistance du sol (12). Le module de cisaillement ainsi que le taux de pores du sol peuvent être calculés à partir de la résistance. Le transducteur (13) est excité par un signal de courant c.a. dont la fréquence varie progressivement sur une plage présélectionnée selon un taux de variation variable ce qui donne un plus large contenu de spectres de forces aux basses fréquences qu'aux hautes fréquences tout en maintenant la force à un niveau sensiblement constant.

Abstract: A pressurizing apparatus for pressurizing fluid contained in a patient fluid bag (14) is described which has a novel teardrop pressurizing chamber. The pressure apparatus includes a door and base which each has complimentary teardrop cavities formed therein. When the door (24) is in the closed position over the base (26), the teardrop pressurizing chamber is formed. A teardrop bladder bag (90) is located interior to the base and can be inflated to apply pressure to a patient fluid bag. A regulator (16) allows adjustment of the desired pressure. A gauge allows monitoring of the pressure. A valve allows the pressurizing device to be turned on and off. The teardrop pressurizing chamber allows the pressurizing apparatus (10) to come up to pressure in a more expeditious manner. The conformance of the pressurizing means to the teardrop pressurizing chamber also adds to the efficiency of the pressurizing of the patient fluid bag and, additionally, allows for uniform pressure throughout a procedure.

Abstract: A system and method are provided which have the ability to print whole documents at a time, rather than page by page. The data for an entire multi-page document is fed directly to an output device, and then a print engine. The data stream includes a record layout including data field codes which tell the data system and/or raster image processor where to print strings of variable information in a document so that the strings only need be provided once even if printed in multiple places within the document. Data flows in the data stream to the print engine as the raster image processor functions in real time. The system has the capability to manipulate and transfer data at 10 Mbytes per second, which translate into a transfer rate of approximately 92,000 characters per second at up to 1,000 fet per minute print speeds, for up to six controllers. Either fixed or variable graphic elements may also be transferred in this same manner as the data and processed by the RIP in real time and printed at the same speed as the data.

Abstract: A self-propelled forage harvester is provided with a throughput measurement device comprising a computer which makes use of respective signals representative of the displacement of a movable upper pre-compression roll relative to a fixed lower pre-compression roll, of the speed of the lower roll, and of the force exerted by the mat of crop passing between the rolls on the upper roll once the upper roll reaches its upper limit position in the calculation of the crop throughput value. An additional input signal that may be used in the calculation of the crop throughput is generated by a light barrier which determines whether or not any crop is exiting the discharge chute of the forage harvester, this signal causing the throughput calculation to indicate zero throughput when no crop is exiting and causing the calculation to indicate a minimum amount when the upper pre-compression roll is in its lower limit position with crop being sensed exiting the discharge chute.

Abstract: An EOT unit on a railcar is equipped with a microprocessor controlled regulating valve system to control pressure within the brake pipe. The system includes a microprocessor unit, a pressure transducer, a regulating valve device and an electro-pneumatic control mechanism. The microprocessor receives from the transducer an electrical signal indicative of actual brake pipe pressure and from the locomotive a brake command signal indicative of desired brake pipe pressure. The microprocessor issues electrical control signals to the mechanism when the brake command signal requires either a service brake application or an emergency brake application. The regulating valve device defines a primary passage, a branch passage, an exhaust passage, and an elongated valve bore in which a diaphragm operated piston is located above an elongated valve stem. The valve stem features two valves with the first located between the primary and exhaust passages and the second between the exhaust and branch passages. The primary and branch passages communicate with the brake pipe, and all of the passages communicate with the bore. Responsive to a control pressure provided by the mechanism to a volume above the diaphragm, the piston moves the valve stem within the bore to the extent dictated by that control pressure. For a service control pressure, the piston opens only the first valve to the extent dictated by that service control pressure. For an emergency control pressure, the piston fully opens the first and second valves to reduce the pressure in the brake pipe at an emergency rate.
