Inventor: TSUJIMURA TAKEHISA
IPC: H01L23/04
Filed: 1983-06-24
Abstract: In a leadless chip carrier (LCC) type semiconductor device, a larger number of soldering pads (3, 8) for connection to an external circuit can be formed for a given package size by using different depths of adjacent grooves (611a, 611b, 621a, 621b) formed along the edge face (612, 622) of the package to receive metallization lines (613a, 613b, 623a, 623b). Adjacent soldering pads are therefore located at different depths from the periphery of the package, so that the risk of short circuits caused by solder bridges between adjacent soldering pads is not increased by the increased density.

Abstract: A rigid mount coupler in which all movement required for connecting and disconnecting a nipple (13) occurs within a coupler housing (11). A body member (12) which receives the valved nipple (13) slides within the housing (11) to actuate a locking mechanism (45) to retain the nipple (13). The body member (12) supports the coupler valve (60) in a spring (72) loaded retainer (65) so that the coupler valve (60) and nipple valve (51) engage and are balanced in valve open positions. A second spring loaded device (74, 75) supports the coupler valve (60) at the open position and resists further opening movement, thereby preventing flow checking at the nipple. Seals (32,39,40) between the body member (12) and housing (11) isolate a stepped chamber (38) therebetween in fluid communication with an inner chamber (82) closed by the coupler valve (60). The volume of the stepped chamber (82) changes upon movement of the body member (12) and is dimensioned to correspond inversely to changes in volume of the inner chamber (38) to prevent a fluid lock condition.

Abstract: In order to ensure that the vibrations of a system under test (12) are in accordance with a reference spectral density Z(w), the system (12) is driven by a signal x<sub>n</sub>(t) provided by an inverse discrete Fourier transform (24) with random phases introduced by a function R<sub>n</sub>(w) and the response spectral density Y<sub>n</sub>(w) provided by a DFT 16 is brough into agreement with Z(w) by a feedback loop. Moreover, in order to ensure that this is done in one iteration, X<sub>n</sub>'(w) is derived from x<sub>n</sub>(t) by a DFT (26) and divided (28) by Y<sub>n</sub>(w) and the quotient is multiplied (30) with Z(w) to provide the new input X<sub>n</sub>(w) for the IDFT (24). The division cancels out the random factor which is present in both X'<sub>n</sub>(w) and Y<sub>n</sub>(w). The system thus equalizes both rapidly and stably.

Abstract: The gas is detected with a device (3, 4, 5, 7, 8, 9, 10, 11) whose gas sensor (5) contains at least one metal oxide and changes its optical properties on exposure to a gas. The metal oxide or metal oxide mixture may contain redox catalysts. A source (3) directs a radiation (4) at the gas sensor (5) in such a way that the radiation is either reflected at the gas sensor or passes through it. The reflected or transmitted radiation (7), modified by the optical properties of the gas sensor, enters a receiver (8). An evaluation circuit (10) connected to the output of the receiver measures the intensity of the radiation (7) modified by the gas sensor or compares the intensities of the radiation (4) directed at the gas sensor and the radiation (7) modified by the gas sensor with one another. The result of the measurement or of the comparison is fed to an indicating device (11). Optical waveguides can be used to guide the radiation (4) between source (3), gas sensor (5) and receiver (8). <IMAGE>

Abstract: A video brightness control system for high performance CRT displays including a buffer amplifier for receiving high speed video information and applying it to a gain control variable resistor serving as a contrast control. An ambient light sensor drives a nonlinear amplifier to provide an ambient light signal which is in proportion to the logarithm of the ambient light level over a wide range. A manual brightness control potentiometer is adjustable to provide a constant brightness signal. The video information signal, the ambient light signal, and the manual brightness control signal are added together by a summing device, with the resultant signal approximating a logarithmic characteristic. The output of the summing device is applied to a gamma correction amplifier which drives a video driver amplifier, the video amplifier, in turn, drives the CRT. The gamma correction amplifier and video driver in combination with the video transfer function of the CRT approximates an exponential transfer function, thereby creating CRT screen brightness which is an antilogarithmic function of the total video signal appearing at the gamma correction amplifier input. This results in automatic brightness control as a function of ambient light level, minimum interaction between brightness and contrast controls, and a gamma characteristic which provides a reasonable approximation to the variation of brightness difference threshold of the eye.

Abstract: A pressure transducer assembly (10) is disclosed for directly monitoring pressure in a fluid which flows through the assembly. The assembly includes a housing (16) defining a chamber (18) therewithin and having an inlet port (26) and an outlet port (28) in fluid-flow communication with the chamber. An electrically insulated body element (24) is sealed within the chamber dividing the chamber into a first chamber (20) and a second chamber (22). The first chamber is in fluid-flow communication with the inlet and outlet ports. The second chamber is separated from the first chamber by a fluid-tight seal such that any fluid present in the first chamber cannot enter the second chamber. A pressure transducer sensor (32) is secured in the insulated body and exposed to the first chamber such that the sensor can determine the pressure in a fluid in the first chamber and convert the pressure into electric impulses. The sensor is separated from the fluid in the first chamber by an insulating medium (34) across which fluid pressure can be determined. Connected to the sensor are electrical conductors (36) which extend through the insulated body and into the second chamber. The second chamber provides an engagement site for an electrical connector (38) which can inte- connect with the electrical conductors and provide an electrical path through which the electric impulses generated by the sensor can be transferred to a monitor (56).

Abstract: A system for measuring non-linear parameter B/A of an ultrasonic medium (8) such as a living tissue (namely a value which indicates a rate of change of sound velocity with change of pressure) utilizing reflected ultrasonic waves. The system is operable to provide a measuring burst pulse (W m ) having a comparatively high frequency, and a pumping pulse (Wp) having a comparatively low frequency and a high sound pressure for obtaining a change of pressure in the medium, and to transmit those pulses in the same direction into the medium so they are superposed. The system is operable to detect phase of reflected waves from each region of the ultrasonic medium (8) and to effect differentiation. Thereby distribution of B/A along the transmission direction of the pulses in the medium can be obtained.

Abstract: Coal is gasified in the plant which also includes a treatment for the purification of the high-pressure crude gas. In general, the crude gas is purified by wet scrubbing. However, this type of purification, entails a substantial lowering of the crude gas temperature and hence a loss of energy. This is a disadvantage particularly if the crude gas is to be charged to the combustion chamber of a steam generator. By contrast, the invention now proposes that the equipment serving for the purification of the crude gas has at least two parallel-arranged cyclones on the inlet side, which can be connected or disconnected individually. Dry purification of the crude gas takes place at an at most small temperature loss, and the gas rate corresponding to the best possible degree of purification can be adjusted by the particular number of cyclones put into operation to the gas rate actually leaving the gas generator or to the gas rate in fact required for charging to the steam generator, without the need for the insertion of buffer capacities.

Abstract: A barrier structure particularly for use in protective doors designed to resist explosive charges applied to their outer surfaces, comprises a layer of timber 5 located between the outer and inner door plates 2 and 4. The purpose of the timber is to absorb the shock and thermal energy of an explosion occurring at or near the outer plate 2 and thus shield the rearward portion 4 of the structure from the damaging effects of the blast. Preferably the outer plate 2 is readily detachable from the remainder of the structure under the action of blast pressure transmitted to the interior of the structure, thereby permitting rapid dissipation of the blast and avoiding a concentration of pressure over a small area of the timber 5.

Abstract: A continuous hydrolysis process for the hydrolysis of wood or other lignocellulose material into sugars and other products has an overall countercurrent flow of liquids and solids but an integral co-current flow of the liquids and solids as part of the process. 
     As shown in Figure 2, woodchip or other feedstock is formed into a slurry which is acidified, pressurised and heated before being hydrolysed in reactors J. Three heat exchangers L1, L2 and L3 form a closed circuit in which exchanger L2 recovers heat from the slurry, L1 returns heat to the slurry and L3 makes up lost heat. The slurry is cooled before pressure reduction by pressure reducing means N and separation of the solids and liquid. The cooling prevents flashing to steam of part of the liquid in the slurry so that the process is single phase where generation of steam is avoided. After separation the solids can proceed to further processing or to discharge as lignin as indicated by arrow B. The liquid can proceed to further processing or discharge as indicated by arrow D.
