Abstract: The burner head has a fuel lance (1) which runs through the burner head in its length and which ends on the downstream side with a fuel nozzle (2). Acting around this fuel lance (1) is a combustion air duct (4) which stops on the downstream side with a screen (3). Arranged around this first combustion air duct (4) is a further combustion air duct (6) which passes on the downstream side into an outlet, where a number of guide members (9) is situated, which impose a twist on at least the combustion air flowing through this duct. Also affected by this twist are the waste gases (10) flowing in through a tangential duct (11) in the region of the guide members (9), as a result of which there is good mixing between the two media. Acting on the downstream side of the fuel nozzle (2) is a premixing zone (8), adjoining the end of which is a vortex backflow zone (14), As far as this vortex backflow zone, the combustion chamber is provided with a premixing pipe (13), and subsequently a combustion pipe (19, 19a) acts, which has a greater cross-section in relation to the premixing pipe (13). At the transition of these two pipes, a vortex ring (17) is formed, which surrounds the vortex backflow zone (14) and ensures that the flame stabilisation is maintained, by the last-mentioned zone not being able to flatten. The initial ignition (18) of the mixture takes place in the vortex ring (17).

Abstract: An optical space switch includes a polarization controller (2), a beam splitter (1), a first reflection block (5) and a second reflection block (8). The polarization controller has a first mode and a second mode. The polarization controller maintains the polarization of input light in the first mode and changes it by 90° in the second mode. The first reflection block includes a quarter wave plate (3) and a light path changing element (4). The input light from the polarization beam splitter is reflected by the first reflection block. During this time, the input light passes through the quarter wave plate twice. Thus, the polarization of the input light is changed by 90°. Further, the light path of the input light is shifted by a predetermined distance by the light path changing element. The second reflection block has a quarter wave plate (6) and a mirror (7). The second reflection block receives the input light from the polarization beam splitter, and returns it thereto. During this time, since the input light passes through the quarter wave plate of the second block twice, the polarization thereof is changed by 90°. The input light is emitted from the polarization beam splitter via a first output path or a second output path.

As a result of this, the unity-gain-­bandwidth remains substantially the same.

Abstract: A voice synthesizing apparatus of this invention is arranged to synthesize a voice from text data composed of either character codes or a series of symbols by generating a sound source based on a series of sound-source parameters and synthesizing the sound source on the basis of a series of synthesis parameters. The voice synthesizing apparatus is provided with a sound-source generating circuit for generating the aforesaid sound source from a signal obtained from an instrumental sound generated with a musical instrument. This arrangement serves to easily synthesize voices which convey language information and yet which simulate the sounds of musical instruments such as a guitar, a violin, a harmonica, a musical synthesizer and the like.

Abstract: A multi-cellular power field effect semiconductor device includes a high conductivity layer of metal or a metal silicide (158) disposed in intimate contact with the source region (120) of the device. This high conducrivity layer is self-aligned with respect to the aperture in the gate electrode (131) through which the source region is diffused. The presence of this high conductivity layer allows a substantially smaller contact window to be employed for making contact between the final metalization (134) and the source region. As a consequence, the aperture in the gate electrode and the cell size of the device can both be substantially reduced. The device has substantially improved operating characteristics. A method of producing the device is also described.

Abstract: The heat-insulating engine with swirl chamber of this invention injects a fuel at a low pressure along the inner wall surface (21) of swirl chambers (4) having a heat-insulating structure by subsidiary nozzles (2) equipped with an accumulation chamber for accumulating temporarily the fuel from a fuel pressurization pump (22,28) and having a needle valve opened and closed electrically, from the second half of an intake stroke to a compression stroke, and then injects mainly the fuel from a fuel injection pump (23) by main nozzles (3), into the swirl chambers (4) from the second half of the compression stroke to an expansion stroke. Atomization of the fuel from the subsidiary nozzles (2) may be to such an extent that the fuel merely attaches to the wall surface (21); hence, the subsidiary nozzles (2) can be of accumulation type low pressure injection type. Accordingly, the fuel pressurization pump (22,28) itself can be made compact in size and light in weight and the cost of production can be reduced. The fuel from the subsidiary nozzles (2) is injected to the wall surface (21) of the swirl chambers (4) in the contact state so as to deprive the wall surface (21) of the heat and thus to recover the heat. Main injection is effected following the subsidiary injection and a rich mixture is generated inside the swirl chambers (4) so as to restrict the generation of NOX and to improve cycle efficiency. Furthermore, it is possible to prevent a lean mixture from diffusing into cylinders (14). since the fuel of subsidiary injection is caused to stay inside the swirl chambers (4), degradation of hydrocarbon components can be reduced.

Abstract: A fuel filler assembly (10) for a fuel tank (12) of a vehicle including a filler tube (14) for directing fuel to the tank (12) and a vent tube (15). The vent tube (15) is closed by a float valve (24) when the tank is filled to capacity and an equalising port (27) is provided in the vent tube (15) to balance the pressure between the upper portion of the filler neck and the vapour dome area of the tank. When pressure is relieved either by removing the filler cap or by opening of a filler cap relief valve, a relief valve (25) located above the float valve (24) and within the vapour dome of the fuel tank operates to allow pressure relief from the vapour dome of the fuel tank. A check valve (20) is provided in the filler tube (14) at the fuel tank (12). The check valve (20) in the filler tube (14) features a valve element (38) having cylindrical sides (39) and a hemispherical end (41) which is received in a housing (32) having cylindrical walls (34) and an annular seat (40) against which the hemispherical end (41) of the valve element (38) seals. The check valve (20) in the filler tube (14) is spring biased into a closed position with a force less than that required to automatically shutoff fuel dispensing.

Abstract: La présente invention décrit une machine de faible volume à dépôt ionique en phase vapeur, particulièrement adaptée à l'application anti-reflet sur les verres de lunettes. La machine a un compartiment de dépôt en phase vapeur (104) contenant au moins deux matériaux cibles pour pulvérisation (134, 136) et un écran amovible (140) qui recouvre la cible que l'on n'est pas en train de pulvériser. Cet écran peut changer de position de sorte que l'une des deux cibles peut subir ce procédé, tandis que l'autre ou les autres restent fermées. La machine est équipée d'un système de commande. Ainsi, lorsque les articles sont placés dans le compartiment fermé, le procédé peut s'effectuer automatiquement sans qu'il soit nécessaire d'ouvrir le compartiment pendant ce temps, ce qui permet de pulvériser les matériaux-cibles selon une séquence et dans une période programmées.

Abstract: Apparatus and method to provide a controllable one-dimensional array or two-dimensional array of delay times for an array of acoustic signals propagating in a plurality of bodies (15) of piezoelectric material. Each piezoelectric body is provided with three or more pairs of electrodes (19-1, 19-2, 21-1, 21-2, 23-1, 23-2), with the first and second electrodes of a pair being spaced apart and positioned on first and second surfaces, respectively, of the piezoelectric body (15). As an acoustic signal (11) propagates longitudinally in the piezoelectric body (15), an electrical voltage signal is generated between each electrode pair (19-1, 19-2, 21-1, 21-2, 23-1, 23-2) as the wave passes between the two electrodes of that pair. Time delay is controlled by choice of the longitudinal position of each electrode pair along the piezoelectric body (15).
