Inventor: FRIEDMAN HARVEY S
IPC: H01L23/36
Filed: 1988-06-30
Abstract: A thermal package (10) for electronic components, such as semiconducting chips (12), is disclosed. Each chip is connected to a printed circuit interconnect substrate (14) by flexible Tape Automated Bonding leads, and a pliant foam pad is attached to the surface of each chip adjacent the printed circuit interconnect substrate. A heat spreader (18) is attached to the major surface of each chip above the printed circuit interconnect substrate. The heat exchangers (18) are mounted to a support plate (20) that is disposed above the printed circuit interconnect substrate. An external heat exchanger (28) is attached to the exposed major surface of the support plate. The heat spreaders are secured to the support plate so they are urged upwards against the external heat sink. Heat generated by the chips is conducted through the heat spreaders to the external heat sink. Conductors on the support plate and the heat sink are used to provide a voltage to the chips.

Abstract: A process and apparatus for the production of generator gas and activated carbon from solid fuels is proposed, in which, in a first gasification stage, the fuel is fed by forced bottom-charging and preheated air in cocurrent of fuel and air and in which, in the second gasification stage, an intermediate gasification takes place with addition of secondary air and subsequently, in a third gasification stage, the gas is reacted with incandescent coke or charcoal, the heat of the issuing gas being used for heating the air. 
<??>The fuel entering the first gasification stage in the centre is here passed from the inside outwards and then upwards. A part of the entering fuel is precombusted in a prechamber connected with the preheated air feed, in order to reduce the oxygen content of the preheated air. In the intermediate gasification, the gas with the admixed air is passed through a Venturi nozzle with a diffusor, the fly coal entrained from the first gasification stage being at least partially recycled into the throat of the Venturi nozzle, and the recycle being assisted both by vacuum in the Venturi nozzle and mechanically.

Abstract: A computer includes a main processing unit having arithmetic logic, memory address control, input/output address control, and execution control. The computer also has an operating system program which includes an interrupt handler module. A variable frequency clock oscillator is disclosed which is controlled by the operating system via the execution control unit of the main processing unit. Machine level instructions in the executing program change the clock speed whenever it is necessary to keep the computer in synchronism with one of its I/O adapters or to speed up the clock when slow speed circuits are not being utilized. Clock speed is changed by the interrupt handling module. Circuits and programs, which require longer cycle times to execute properly, are placed together on interrupt levels. For example, the machine check program re­quiring the slowest clock speed is assigned to inter­rupt level 0. I/O adapters using low-speed circuitry are assigned to interrupt levels 1, 2 and 3. High speed circuitry adapters are assigned to interrupt levels 4-7. Whenever an interrupt is generated, the machine language program serving the interrupt first changes the speed of the oscillator clock to that speed defined for the interrupt level on which the interrupt was received. When the interrupt has been serviced, the oscillator clock speed is restored to that speed of the program operating on the interrupt level which has just been interrupted.

Abstract: A display apparatus utilizing afterimage comprises a plurality of display boards disposed alongside a track of vehicles at such intervals that a passenger in a running vehicle can see the character or pattern on the display boards in a continuous flow by the action of afterimage. Shielding means having a vertical slit is provided at a distance away from the display surface of each display board to cover the display surface. A passenger in a running vehicle sees one display board after another disposed alongside the track through the slit cut in the shielding means as the vehicle moves forward. Because adjoining display surfaces are kept from overlapping, the passenger can clearly see the character or pattern that appears to remain at a standstill or moving.

Abstract: A flow rate control system is disclosed for measurement of ink flow through an ink jet system. The flow rate control system receives an error signal indicative of deviation of flow rate from a set value. The system includes proportional (P), integral (I) and derivative (D) control to generate a control signal based on the magnitude and sign of the error signal. The control signal is used to control the on-time of an ink make-up valve which adds make-up ink to the system as ink is needed to maintain satisfactory operation. In a preferred embodiment, the PID controller has noise reduction capability through the use of clippers and low pass filters. In addition, conditional summation may be employed to minimize "hunting" at low error signal levels.

Abstract: A method for operating a ring spinning machine with the use of a service robot (68) patrolling along a row of spinning stations (16) is characterised in that the service robot in a first movement along the row of spinning stations stores the spinning stations at which there is a yarn break, and in that only in a further, preferably the next movement along this row does the service robot attempt to rectify the yarn breaks previously ascertained and, after this attempt, checks whether it was successful, and if this is not so it classifies the yarn break as not repairable by it and indicates or signals this fact to the attendance personnel. Only in the event of a failure in the rectification of a yarn break is the roving stop device (52) provided at the respective spinning station actuated.

Abstract: This invention presents both a method and device capable of accurately measuring fixed lengths of moving strand or yarn as it is pulled from an essentially continuous source of supply and wound onto a take-up reel by an appropriately powered winding mechanism. In its preferred embodiment, the invention is used to measure lengths of fiber glass strand unwound from forming packages and onto rotating bobbins (4) carried on a twist frame. As its principal component, the invention utilizes a lightweight, low inertia measuring rim (6') supported on a layer of pressurized gas, such as air, so that frictionless rotation of the rim (6) about a stationary hub (10) is thereby made possible. 
     Moving strand is maintained in continuous contact with the rim (6) thereby causing it to rotate. The number of rotations is counted by electrical means and multiplied by the circumference of the rim (6) whereby the length of strand advanced over the rim (6) and onto the rotating bobbin (4) is calculated.

Abstract: An improvement for a semiconductor device in which memory elements and logic elements are formed on the same substrate is disclosed. The semiconductor device is formed so that a concentration of the field inversion preventive layer (105b, 205b, 305b) below the field oxide film within the region where memory elements are formed is higher than a concentration of the field inversion preventive layer (105a, 205a, 305a) below the field oxide film within the region where logic elements are formed. For the method of manufacturing a semiconductor substrate according to this invention which realizes such a structure, there is a method of allowing the concentrations of field inversion preventive layers within the memory element region and within the logic element region to be differently changed, respectively, and a method of first forming field inversion preventive layers within the both regions so that they have a low concentration, and implementing ion-implantation only to the memory element region for a second time under the state where the logic element region is covered with resist, to thus provide an inversion preventive layer of high concentration.

Abstract: A CPU 1, responding to a key input from a keyboard (29), issues a parameter read-in command to an HDC (15). Upon receiving the parameter read-in command, the HDC (15) reads out from a predetermined sector of an HDD (17) parameters of the HDD (17) such as the number of heads, the number of cylinders and the number of sectors per track. The read-out parameters are set in a sector buffer (15a), and the CPU 1 is interrupted. In response to the interrupt signal, the CPU 1 reads the parameters from the HDC (15) and stores them in a battery backup memory. In addition, the CPU 1 discriminates the type of the HDD (17) on the basis of the parameters and enables a display (33) to display the discriminated type and the parameters of the HDD (15).
