Patent EP-0268865-A2 (EP)
Inventor: BANK JUDITH HELEN
IPC: G06F12/00
Filed: 1987-10-30
Abstract: An apparatus and method is disclosed for improving communication among processors by reducing I/O to a data area accessed by each processor and by increasing the amount of time that a processor can update the data area. Reducing I/O time and increasing update time speeds up data area I/O operations thereby increasing processor performance. In particular, a journal is implemented to reduce I/O to a subsystem's shared data area on a non-volatile shared storage device. The journal provides for the increase in the amount of time that a processor may have access to the shared data area. Also, two versions of the data area are implemented in order to insure the integrity of the continuously updated data area. The two versions flip-flop depending upon which one has the most recent updates. That is, the version that has the most recent updates becomes the to-be-read-from data area and is read by the processor that currently has access to the shared data area during this series of I/O operations. The other version becomes the to-be-written-to data area and is written to by the processor that currently has access to the data area in order to update the to-be-written-to version to the current level. The to-be-written-to version then becomes the to-be-read-from version during the next series of I/O operations.

Abstract: A vehicle suspension system having a suspension member (5) extending in the longitudinal direction of the vehicle body (1) for controlling the longitudinal displacement of a wheel (1b), which comprises a shock absorbing means (6) inclined forward or rearward and a resilient means (5b) for defining the resilient characteristics of the suspension member in the longitudinal direction. The resilient characteristics are determined to exhibit soft resilience in the direction of a horizontal component of a reaction force (f) exerted from the inclined shock absorbing means and to exhibit hard resilience in the opposite direction to the horizontal component. According to the present invention, the horizontal component of the reaction force is largely absorbed by the resilient means (5b). Hence, shock due to the horizontal component can be avoided and the riding qualities of the vehicle can be improved. In addition, the movement in the opposite direction to the horizontal component of the reaction force is suppressed by the resilient means (5b). Therefore, change in the wheel attitude can be suppressed and the motive stability and the drivability of the vehicle can be improved as well.

Abstract: A lens shutter comprises a shutter blades opening and closing lever (4) and an electrostrictive strain element (5) driving the lever (4). The arrangement being such that inertia forces acting on said lever (4) through engagement with said element (5) and vice versa are counterbalanced by each other, in order to eliminate variations of exposure caused by various posi­tions of a camera. The basic portion of the electrostrictive strain element (5) is secured to a retaining member (6) sup­ported rotatably on a shutter base plate (1) and the retaining member (6) may well be biased by a spring (8) to increase the inertia force of the electrostrictive strain element (5). Thereby, even if a shock is applied to the shutter from the outside, the shutter blades (2, 2ʹ) are not inadvertently opened and closed. The rotation of the retaining member (6) to rotate the opening and closing lever (4) in a wrong direction is prevented by an eccentric pin (9).

Abstract: The method is for cutting noncrystalline plate-type objects (1) along a linear, electrically heated hot zone which consists of a pasty track of material which is subjected to a consolidation treatment and which is applied nondetachably to the surface of the object to be cut along a desired line of cut. To cut plate-type aluminium oxide objects, in particular thick-film substrates, the track of material is made of an electrically conductive material. For the purpose of cutting, an electric current is passed through the electrically conductive cutting track (5, 15, 17, 33, 37) and thereby heated up. <IMAGE>

Abstract: The interface apparatus couples a video recording device to the parallel data channel of a computer system and also to the computer video output circuitry, so that both digital information (such as computer programs or data files) and analog information (such as video signals for displaying on a television monitor) may be stored on the same video recording medium. The apparatus permits storage of both digital information and human readable information in a convenient back-to-back relationship. The interface permits the computer video monitor to directly display stored or live video broadcasts, without computer intervention. The invention allows the display of graphic, photographic and motion picture information in analog format thereby eliminating information lost through digitizing. An automatic search mode permits the computer to direct the video recording device to search for a predetermined location on the recording medium at high speed without human intervention. The computer is capable of controlling the video recording device by means of the remote control port of the video recorder.

Abstract: The invention relates to a method for manufacturing reinforced products, in which the reinforcement comprises an expanded material, and also relates to products produced in accordance with the method. The expanded material may comprise steel, iron, plastics of various kinds, orfoamed plastics. In the manufacture of sheet-like products, the reinforcement is permitted to protrude beyond the edges of the product, so that an overlap-free joint can be formed between the sheets. The products can also be manufactured in various shapes and forms, pipes, corrugated sheets etc. The sheets and products may be comprised of a matrix material in the form of cement, concrete, plastics etc., although the matrix may also comprise the same material as that used for the reinforcement. An optimum structure can be obtained by adapting the perforations and the stretching of the reinforcement material to the expected stresses on the products.

Abstract: An improved discrete excitation coil (50) is provided in a continuous casting machine (10) for generat­ing an electromagnetic levitating and stabilizing force which acts upon the meniscus of the molten metal in a mold cavity (26) at the region of an upper inlet (28) to the cavity (26). The force counteracts the head pressure of the molten metal contained 
within a pouring tube (18) which extends through the upper inlet (28) from above the cavity (26), thereby providing a seal in the area of separation therebetween which prevents overflow of molten metal through the inlet. The excitation coil (50) includes an outer electrical conductor (58) which defines multiple electrical conductor turns (60) disposed in series and is capable of carrying an electrical current of adequate density to generate the electromagnetic force, and plural inner fluid channels (62) which define fluid flow paths being surrounded by, and in contact with, the outer electrical conductor (58).
