Patent EP-0620497-A2 (EP)
Inventor: HASHIMOTO KEIJI C O DAI NIPPON
IPC: G03F1/00
Filed: 1994-04-11
Abstract: A halftone phase shift photomask designed so that it is possible to shorten the photoengraving process, use a production line for a conventional photomask, prevent lowering of the contract between the transparent and semitransparent regions at a long wavelength in the visible region, which is used for inspection and measurement, and also prevent charge-up during electron beam exposure, and that ordinary physical cleaning process can be used for the halftone phase shift photomask. The halftone phase shift photomask has on a transparent substrate (1) a region which is semitransparent to exposure light and a region which is transparent to the exposure light so that the phase difference between light passing through the transparent region and light passing through the semitransparent region is substantially π radians. A semitransparent film that constitutes the semitransparent region is arranged in the form of a multilayer film including layers (3, 4) of chromium or a chromium compound. For example, the layer (3) is formed of chromium oxide, chromium oxide nitride, chromium oxide carbide, or chromium oxide nitride carbide, and the layer (4) is formed of chromium or chromium nitride. The layer (3) mainly serves as a phase shift layer, while the layer (4) mainly serves as a transmittance control layer that suppresses the rise of transmittance at the long wavelength side. The semitransparent film is formed by physical vapor deposition.

Abstract: The present invention permits solder joints to be made directly to via and through holes without the solder being wicked into the vias or through holes, by filling plated through holes (14) with an epoxy or cyanate fill composition (16). When cured and overplated, the fill composition (16) provides support for the solder joint (22) and provides a flat solderable surface (18) for the inter-connection. In certain embodiments, the cured fill compositions, offer a further advantage of being conductive. The invention also relates to several novel methods for filling through holes with such fill compositions, and to resistors located in through holes and vias.

Abstract: A delay circuit comprises a first and a second switching transistor, each of which comprises a control electrode and a first and a second main electrode, a first and a second input of the delay circuit being coupled to the control electrode of the first switching transistor and the second switching transistor, respectively. A first and a second output of the delay circuit are coupled to the second electrode of the first and the second switching transistor, respectively. The first electrodes of the first and the second switching transistor are coupled to one another and, via a current source, to a first power supply terminal. The outputs are coupled to a second power supply terminal via respective load circuits. Respective clamp circuits are coupled to the outputs in order to limit maximum attainable differences between a voltage on the second power supply terminal on the one side and a voltage on the respective outputs on the other side.

Abstract: The invention concerns a method of transforming an input image, which is generated by an X-ray photograph, includes attenuated structures and consists of pixels which are defined by their co-ordinates and their respective input image value, into an essentially distortion-free output image, which consists of pixels which are defined by their co-ordinates and their respective output image value. The assigned co-ordinates in the output image are determined from the co-ordinates of a pixel in the input image, and an output image value is derived from the input image value of the relevant pixel. The time for the transformation can be considerably reduced by a threshold operation to determine those pixels (u, v) of the input image in which the attenuated structures are represented, and by carrying out the transformation only for these pixels. <IMAGE>

Abstract: A prepayment commodity supply system for use in the supply of utilities such as electricity, gas and water to a customer comprises a prepayment token, typically a memory card or a smart card, into which credit data representative of an amount of credit or an amount of the commodity is entered by a vending machine in return for payment by the customer. The token is then inserted by the customer into a commodity supply control device, typically a meter, to enable the supply of an amount of the commodity determined by the credit data. The system includes simple (or "dumb") vending machines which are cheap enough to be installed in post offices, corner shops and the like, and each of which communicates by phone with a more sophisticated "special action partner". The special action partner periodically downloads a "grey list" of customers/tokens requiring some kind of special action to its dumb terminals, and each of the latter, on recognising a customer/token on the grey list, automatically contacts the special action partner, which then performs the special action via the dumb terminal. A particular special action is the creation of a duplicate token to replace a lost token, achieved by using an authorising code number which is given to the customer when he reports the loss and which is then entered into the dumb terminal along with a blank token to enable the special action partner to create the duplicate via the dumb terminal.

Abstract: A system for controlling fuel metering in an internal combustion engine using a fluid dynamic model with the quantity of throttle-past air being determined therefrom. Based on the observation that the difference between the steady-state engine operating condition and the transient engine operating condition can be described as the difference in the effective throttle opening areas, the quantity of fuel injection is determined from the product of the ratio between the area and its first-order lag value and the quantity of fuel injection under the steady-state engine operating condition obtained by mapped data retrieval and by subtracting the quantity of correction corresponding to the quantity of chamber-filling air. A pseudo-manifold pressure is estimated and is used for calculating the effective throttle opening area and its first lag value. The pseudo-manifold pressure is corrected by atmospheric pressure, engine coolant water temperature, etc., so as to enhance estimation accuracy.

Abstract: A tamper-evident closure (2) includes a threaded closure and tamper-indicating features. The features have upwardly and inwardly folded tabs (121) which lock against the lower surface of an annular shoulder (202) on a container neck (203) to retain the tamper-indicating features on the neck as the closure is removed. The tamper-indicating features include a pilfer ring (125) to which the tabs are integrally connected. The tabs are resilient and are flexed by the container finish at the joints where they are joined to the pilfer ring. The closure of the present invention may be installed simply by screwing it onto a container neck in a one-step process. The flexible tabs assist in guiding the closure and centering it when installed onto the container neck and do not require the holding of the closure or the container finish to close tolerances in order to be consistently effective. A thin web (123) of material is provided between the tabs which prevents the outward bending of the tabs which may occur during shipping or handling. The invention also provides the tamper-evident closure and container combination.

Abstract: Oxygen is recovered from a heated, compressed, oxygen-containing feed gas by selective permeation of oxygen through an ion transport membrane separation system and the hot, pressurized non-permeate gas is passed through an expansion turbine to recover power for compressing the feed gas and optionally generating electric power. Membrane performance and process heat recovery are enhanced by the addition of water to selected process streams. Steam raised by process heat is used to sweep the permeate side of the membrane to increase the oxygen permeation rate. The injection of partially or fully vaporized water into the expansion turbine inlet gas recovers process heat and increases mass flow to the turbine.
