Patent EP-0268552-A1 (EP)
Inventor: BRENT RICHARD JOHN
IPC: G01J1/42
Filed: 1987-10-09
Abstract: There is described a method of determining the contrast grade of the paper to be used to print a black and white photographic negative which comprises placing a photocell in the darkest significant area of a projected negative image and noting an indication of the light received or calibrating the photocell so when the photocell receives light of the same level it will indicate this, then placing the photocell in the lightest significant area of the projected image of the negative and reducing the light reaching the photocell using graduated steps until the light reaching the photocell is of the same level as the light which reached the photocell when it was placed in the darkest significant area of the projected negative image and noting the step employed to achieve this equivalence and selecting the contrast grade of the paper which is indicated by the step which achieved equivalence. 
     The method can be performed using an enlarger or by use of a modified light exposure meter.

Abstract: Ensemble à écrou rapide et procédé de fabrication de certaines versions dudit ensemble. Celui-ci comprend un corps d'écrou (41), qu'on obtient par rétrécissement magnétique d'un tube d'acier à parois étroites, afin de former une cavité extérieure et intérieure à faces multiples.

Abstract: Milieu de transfert d'allumage servant à relier l'étage d'allumage et les étages successifs de combustion d'un dispositif pyrotechnique comprenant un tissu en charbon sur lequel est déposé un oxydant inorganique, tel qu'un nitrate de potassium. Le milieu peut également comprendre une ou plusieurs substances supplémentaires servant à modifier les caractéristiques de combustion ou le dégagement de chaleur; par exemple, un milieu contenant de 1,0 à 3,5 parties en poids à sec de nitrate de potassium pour une partie de tissu en charbon peut également comprendre de 0,05 à 0,40 partie d'acide picrique. Dans cet exemple, soit l'acide picrique peut être adsorbé sur les fibres de tissu avant le dépôt du nitrate de potassium sur le même tissu, soit les deux substances peuvent être déposées simultanément sur le tissu à partir d'une solution aqueuse.

Abstract: Commercially produced chitosan applied to cereal crop seeds at rates of 60 µg to 1000 µg per gram of seed enhances 
root development, crown diameter, mature straw strength and crop yield. Dry chitosan, when dissolved in dilute acid and 
neutralized, is applied directly to cereal crop seed with only minor modification to seed treating machinery and methods. 
In addition to a clear benefit in cereal crop yield, the chitosan treated seed can be planted early to reduce erosion and it 
can be planted in regions having soil infested with root rotting organims and not suffer extensive lodging that would pre­
vent seed recovery by commercial harvesters.

Abstract: Grâce à l'application d'un polymer filmogène résistant aux hautes températures, on a réussi dans le passé à stabiliser des couches de photoréserve, telles que notamment les couches utilisées pour des géométries à haute résolution dans des applications micro-électroniques, pour combattre les distorsions ou les dégradations causées par la chaleur produite durant des opérations d'attaque ultérieure, d'implantation d'ions et similaire. On a découvert que, lorsque l'épaisseur de la couche de photoréserve dépasse un micron environ, le revêtement du polymère filmogène a tendance à subir des distorsions et/ou à produire des fissures, des ruptures et similaires dans la photoréserve, ce qui a pour conséquence une perte de la géométrie requise dans l'image de la couche de photoréserve. Selon la présente invention, on peut surmonter ce problème en appliquant le polymère filmogène sous la forme d'un spray vaporisé par ultrasons (24) dans des conditions contrôlées.

Abstract: Between the head amplifier (3) and the frequency demodulator (7) of the signal path of a frequency-modulated luminance signal, a frequency-selective edge delay circuit (5) is additionally arranged in a video device, which delay circuit delays the pulse edges and thus the pulses at pulse frequencies for a luminance which is in the region of the black value of the luminance, and passes, undelayed, edges of pulses of pulse frequencies for luminances which are located in the vicinity of the white region. In the area of the luminance jump, this narrows the first pulses for the bright luminance or increases the pulse interval between the pulse series for the bright luminance and the pulse series for the black value in such a manner that they represent an excessive white value or black value and mark an overshoot at the luminance jump. <IMAGE>

Abstract: The fuel cell power plant operates at higher reactant pressures, and thus higher power density (lower cost) and efficiency, by providing reactant reformer steam (42) from a separate steam boiler (42). Instead of supplying coolant steam to the reformer, the coolant is operated in a closed loop apart (10, 12) from the reformer (46), and the coolant steam is used to drive a steam generator (20, 22) to produce additional electricity. A portion of the raw fuel (40) is burned within the steam boiler and the remainder is passed through the reformer and thence to the fuel cells (2). Boiler exhaust (64) is used to drive a turocompressor (62) which pressurizes the air (30) used on the cathode side (6) of the fuel cells.

IPC: H01L21/822
Filed: 1988-08-27
Abstract: Switched body circuitry is provided to prevent a system I/O from being effected by the loss of power supply or ground to an MOS integrated circuit within the system. A semiconductor substrate of a first conductivity type has formed therein a well region of a second conductivity type opposite to that of the first conductivity type. First, second, third and fourth spaced-apart shallow diffusion regions of the first conductivity type are formed at the surface of the well region. The first and fourth of these regions are electrically connected to the well region through ohmic contacts. A first gate electrode, which overlies a first channel region between the second diffusion region and the third diffusion region, is connected to provide the proper logic function on the data line. This first gate electrode and the second and third diffusion regions combine to form an MOS transistor which is either an input pull up or pull down device or an output pull up or pull down driver of the MOS circuit. An I/O pad of the MOS circuit is connected to the second region and to a second gate electrode which overlies a second channel region between the third diffusion region and the fourth diffusion region. Thus, the second gate electrode and the third and fourth diffusion regions combine to define a first MOS switched body transistor. A power supply pad of the MOS circuit is connected to the third diffusion region and to a third gate electrode which overlies a third channel region between the first diffusion region and the second diffusion region. Thus, the third gate electrode and the first and second diffusion regions combine to define a second MOS switched body   transistor. These two transistors control the potential of the I/O transistor's body (P-well or N-well) so as to keep the parasitic and ESD protection bipolar transistors and diode turned off during loss of power or ground to the chip.

Abstract: An anchor member assembly is made up of an anchor bolt and an expansion wedge. The assembly can be anchored in a borehole in a receiving material by inserting the assembly and then displacing the expansion wedge relative to a wedge surface on the anchor bolt. At its trailing end, the anchor bolt has an axially extending outwardly flaring head section forming at least a part of a conical surface. The head section can be driven by hammer blows into a wooden member. Initially, the anchor bolt and expansion wedge are in detachable engagement until the head section is driven into the wooden member. Subsequently, as the expansion wedge is axially displaced relative to the anchor bolt, the engagement between them is released and the anchor member assembly is secured in the receiving material.
