Abstract: A method for determining the relative humidity in an interior space without using a special humidity sensor. Includes, passing a flow of air of known tempearture and humidity through the cooling coil (12) of a known air conditioning system for a predetermined period of time. The temperature of the air existing from the cooling coil (12) after the predetermined period of time is measured. A reference temperature differential is determined by subtracting the exiting temperature from the known temperature of the entering air. A flow of air for which it is desired to know the relative humidity is then passed through the cooling coil (12) for the same pre-determined period of time. The temperature of the air entering the cooling coil (12) and exiting from the cooling coil at the end of this pre-determined period of time is determined. The exit temperature is subtracted from the entering temperature to provide the temperature differential for the air of unknown relative humidity. The reference temperature differential is then compared to the calculated temperature differential. If the temperature differential is smaller than the reference temperature differential the air is then known to be more humid than the known relative humidity. If the temperature differential is the same, the relative humidity is the same, and, if the temperature differential is greater the air is less humid than the known relative humidity.

Abstract: A nuclear magnetic resonance imaging capable of controlling a generation of a desired pulse sequence to be used interactively, realizing the adjustment of the pulse sequence easily and accurately, and realizing the high speed pulse sequence execution. The pulse sequence is automatically generated from a basic pulse sequence form and a parameter block storing the imaging parameters affected by the imaging conditions specified interavtively. The pulse sequence is then automatically adjusted to an optimum setting by simulating an execution of the pulse sequence by using simulated RF pulses, gradient magnetic fields, static magnetic field, and nuclear spin density distribution, according to the characteristic parameters measured in advance. In the actual execution of the pulse sequence, the event codes stored in the event memory of the sequence controller are decoded by a plurality of decoders in parallel, and the rewriting of the event memory is realized by using a rewriting table having entries specifying a manner of rewriting each slot of each entry in the event memory, and flags in the event memory indicating an appropriate rewriting table entry for each slot.

Abstract: The data processor    1    has a mode in which instructions are executed one module at a time, the module being a subroutine of high-level language, and a break is activated immediately after executing a return instruction at the end of the module. This mode is set in the control register (MSCNT) by an emulator. In this mode, a return address, the address to which the processing returns from the subroutine, is saved in the return address hold register (RAH) by using a return address which is stacked at a time of executing a branch instruction. The return address saved in the return address hold register (RAH) is compared by the comparator circuit    52    with the return address which is popped up from the stack into the instruction pointer (IP) at the execution of the return instruction at the end of the subroutine. When they agree, a break is activated.

Abstract: Some components of a vibration input to an input guarantee region on a vibration transmission plate directly reach a vibration sensor, but some other components are reflected by the end portion of the vibration transmission plate, and then reach the vibration sensor. An vibration suppressor is attached to a peripheral edge of the vibration transmission plate, and is located along the path of the vibration reflected by the end portion of the vibration transmission plate to the vibration sensor. Since the vibration sensor is attached to a corner portion of the vibration transmission plate where no vibration suppressor is attached, a decrease in coordinate detection precision caused by reflected waves can be suppressed, and a compact apparatus can be realized.

Abstract: In a satellite communication network, a reference station (RS) simultaneously announces a reference time of a reference clock (23) once in a predetermined duration of time to all terrestrial stations of the network. In each terrestrial station (TS(n)) which comprises a local clock (13), a packet forming arrangement (11, 15), a data extracting arrangement (11, 19) for extracting a local time datum from a packet received from a different terrestrial station, and a calculation unit (21) for calculating a propagation delay time between the different terrestrial station and the terrestrial station under consideration by subtracting from the local time datum a current time indicated by the local clock when the local time datum is extracted, a time setting arrangement (25, 27) sets the current time at a sum of the local time datum and a constant preassigned to the terrestrial station in question. The constant is preliminarily decided by calculating a distance on the earth between the terrestrial station and the reference station based on their longitudes and latitudes, calculating a physical length of a communication link by using the distance, and calculating a time necessary for electromagnetic waves to travel the physical length. It is possible to substitute one of the terrestrial stations as a center station for the reference station. The physical length is calculated by furthermore using either one-way propagation delays from the terrestrial station under consideration and from the reference or the center station to a satellite of the network or the longitude of the satellite.

Abstract: Hitherto known industrially used quasi-isostatic pressing processes for the manufacture of precision explosive charges were restricted to use at room temperature. However, this did not allow the manufacture of plastic-bound charges. According to the invention, the material to be pressed (1) is now preheated at temperatures of 100 DEG -120 DEG C and then pressed at pressures of the order of 3500 bar in an autoclave (30) for 0.5-5 minutes and, after a pressure release, cooled during a further phase of a duration of 10-180 minutes at pressures of 50-500 bar. In a further embodiment of the subject of the invention, two autoclaves are used, namely a high-pressure autoclave and a low-pressure autoclave. Type of apparatus for carrying out the process relate to the suitable design of the autoclaves and to the press moulds. <IMAGE>

Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. Other additives may also be included, such as starch, adhesives and cement strength enhancers. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.

Abstract: Method and apparatus for fishing for and/or communicating with subsurface apparatus. In a preferred embodiment, a subsurface logging-while-drilling (5)(LWD) or measuring-while-drilling (MWD) apparatus is placed in tandem with a drill string near the bottom of a borehole. The LWD apparatus includes a surface retrievable component such as a nuclear source carrier with a fishing head facing (53) upwardly. The carrier is releasably secured within the LWD apparatus with means such as a shear pin (19). A wireline conveyed tool (10) having a downwardly facing latching mechanism (153) includes a downhole powered latch for telescopically extending beyond the fishing head (53), forcing a latching lug radially inwardly below the fishing head, and moving axially upward to latch the fishing head. Further upward latch movement causes the fishing head (53) to move upwardly until the shear pin (19) shears which releases the carrier from the subsurface apparatus. The wireline tool (10) with the attached carrier is then brought to surface with the wireline cable (6). In a preferred embodiment, the subsurface apparatus includes a secondary coil (50) within its tubular housing. A primary coil (59) is provided on the wireline tool (10) such that upon the wireline tool landing within the subsurface apparatus, the primary coil is nested within the secondary coil. As a result, a bi-directional communication link is established from surface instrumentation to the subsurface apparatus via the wireline cable (6) and the nested coils.
