Patent EP-0399048-A1 (EP)
Inventor: SANTO KOUICHI
IPC: H01H13/70
Filed: 1989-11-07
Abstract: A cheaply constructed panel switch using a diaphragm which provides touch feeling when it is operated, the switch being used for the electronic devices. The switch does not use a spacer that had hitherto been used to determine the position of the diaphragm (14). Instead, the diaphragm (14) is adhered to the lower surface of a sheet (15) coated with adhesive, and the sheet is adhered onto the insulating substrate (12) to fasten the diaphragm (14). The spacer is no more used to facilitate the method of production, and a panel switch is cheaply obtained.

Abstract: Process for the protection against erosion-corrosion of ducts for transporting steam from the high-pressure stage (1) of a bleeder-steam turbine of a power station to bodies (34, 36, 38) of its low-pressure stage on the one hand and to heaters (22A, 23A) on the other hand, in which most of the water contained in the bleeds and the wet-steam outlets is separated by centrifuging (40, 41), a first fraction of the partially dried steam is superheated and/or dried completely (28 to 33) and is then introduced into the bodies (34, 36, 38) of the low-pressure stage, and an additional fraction of partially dried steam is transferred to the heaters (22A, 23A). The two steam fractions are subjected jointly to drying by centrifuging (40, 41), and the additional fraction is subjected to final drying by centrifuging (6A, 7A). …<IMAGE>…

Abstract: Because formerly known forks are unwieldy and not effective enough, owing to the unsatisfactory shape and arrangement of the prongs, this fork has according to the invention a fork blade -1- which is straight in the longitudinal direction, which has six wedge-shaped prongs directed towards with the tip of the fork, which are in series on one longitudinal side -2- and are at an acute angle to the longitudinal axis of the fork, whereby the longitudinal direction of the prongs results in more dexterous and more ergonomic use and the six prongs have a greater effective width, and which on the other longitudinal side -3- comprises a closed continuous surface which is bent up in a longitudinal trough shape and whose edge runs in a curve to the point of the fork, whereby the straight and closed surface makes it simpler to push food on and also allows flat spreading and scraping and the curved edge can also be used to advantage in curves and on uneven surfaces, and the trough shape also results in a more stable position of the food and the spoon function, and in which the tip of the front fork prong -4- ends at the same point as the longitudinal axis of the fork, so that it can be precisely and easily pushed in and firmly caught by rotation. <IMAGE>

Abstract: A flexible, laminated material (10) for reforming into packages for contents of the type such as oxygen- and flavour-sensitive liquid foods, for example fruit juices. 
     The material displays a carrier layer (11) of paper or paper­board and a preferably extruded layer (13) applied to one face of the carrier layer (corresponding to the inside of the finished package), this layer consisting of a mixture of polyethylene and ethylene vinyl alcohol copolymer. 
     Since the barrier layer (13) thus includes both a polar (the ethylene vinyl alcohol copolymer) and a non-polar (polyethylene) component, the material possesses barrier properties against both polar and non-polar flavour components, at the same time as the material moreover displays tightness properties vis-à-vis oxygen.

Abstract: A braking system for vehicles capable of providing front and rear braking control on a vehicle with a vertical split braking system front to rear in response to an electrical signal (1) generated by operation of the brake pedal, comprises a modulator-type dual brake valve assembly delivering pressure fluid to the vehicle brakes and including solenoid operated inlet and exhaust valves controlling communication between modulator supply and exhaust flows and a solenoid delivery port (16). A solenoid operated modulator may be used solo but for heavier duty the modulator brake valve incorporates a pilot operated hydraulic modulator, the solenoid delivery port (16) being connected to provide the pilot signal pressure. With a normally open solenoid inlet valve and normally closed solenoid exhaust valve the pilot operated modulator responds inversely to the solenoid operated modulator and has a normally closed inlet (1) and normally open exhaust (2) when no brake delivery pressure is commanded by the pilot signal. Anti-lock modulation without the need for a separate hydraulic modulator is possible by providing a control unit (110) generating anti-lock command signals (6, 5) that are given priority over braking command signals (4, 3).

Abstract: The method of producing a means of electrical connection, particularly interconnecting substrates for hybrid circuits, involves the deposition of a layer of untreated ink on a highly heat- dissipating support such as aluminium nitride, followed by a preliminary drying of the ink at a temperature of the order of 100 DEG C to 150 DEG C. This is then followed by firing consisting of
 (a) an elevation in temperature incorporating a phase for the removal of the polymer resins,
 (b) a sintering stage at a temperature of the order of 600 DEG C to 1000 DEG C and
 (c) a delayed cooling. The characteristic feature is that the atmosphere during the stage at which the polymer resins are removed has a low oxygen content lying between 100 ppm and 5000 ppm, whereas the oxygen content of the atmosphere during the high temperature sintering and of the cooling atmosphere must be below about 10 ppm.

Abstract: La présente invention se rapporte à un moule et à un procédé de fabrication d'un tel moule. Le moule de la présente invention est essentiellement composé de soufre, dans lequel est mélangé un matériau de charge dont les particules ont une longueur d'au moins 1,5 fois leur épaisseur. On fabrique le moule en produisant le soufre et le matériau de charge en un mélange fondu du type gel, auquel on donne ensuite la forme désirée. Le moule, avec la forme désirée, constitué par le matériau de moule déjà fondu, est ensuite rapidement refroidi par sa surface, de façon à permettre la solidification du mélange de soufre contenant le matériau de charge. On produit le matériau de moule fondu de préférence en chauffant, à une température d'environ 115 à 160°C, un mélange composé de soufre et de laitier de fer ou de wollastonite finement broyés, avec adjonction à ce mélange d'une fraction d'hydrocarbures, tels que du carburant diesel. On peut séparer le moule de la présente invention en le chauffant, ce qui permet de réutiliser le matériau du moule.
