Abstract: The flat image display device, which is sealed in a vacuum, has a front plate (1) of glass, and a metal trough (2) as the rear side. On the inside of the front plate (1), there is a layer of fluorescent spots (3) and the electrodes required for use of the image display device are located inside the trough (2). These electrodes, i.e. a periodic arrangement of heating wires (4), a segmented opposing electrode (5) on a base plate (10), a perforated accelerating anode (6) inside a frame (11) and a control arrangement (7), are mechanically assembled into one component. In consequence, a stable construction for the electrodes is achieved which at the same time allows simple production of the flat image display device. <IMAGE>

Abstract: A carrier recovery circuit comprises a voltage-controlled oscillator with a π/2 phase shifter coupled to it for generating carriers of quadrature phase relationship. First and second phase comparators respectively detect phase differences between an offset QPSK modulated signal and the carriers of the quadrature phase relationship. Signal from the first phase comparator is delayed by 1/2 symbol duration and applied to one input of a quadri-phase detector having stable phase angles at π/4, (3/4)π, (5/4)π and (7/4)π radian and signal from the second phase comparator is applied to the other input of the quadri-phase detector. A bit timing recovery field (1010 ....1010) of the second channel is detected from the output of the second phase comparator. Signal from the quadri-phase detector is applied to a loop filter and thence to the voltage-controlled oscillator during the time when a bit timing recovery field (BTR) of the second channel is not still detected. To stabilize the operation of the carrier recovery loop of the circuit, the output of the second phase comparator from which that BTR is detected is briefly applied to the loop filter in response to the detection of a BTR of the second channel, instead of the signal from the quadri-phase detector.

Abstract: This invention relates to a cache memory device provided in a computer for providing a high speed access operation to the main memory of CPU. In this device, selection of entry is made on the basis of the operational mode of the computer. Accordingly, data used in one operational mode is stored into one area within the cache memory. So to speak, data will be stored into the cache memory, as being grouped into every data used in respective modes. For this reason, clear operation can be performed with the groups corresponding to respective modes being as units, respectively, resulting in no possibility that data used in other modes are collectively cleared. Eventually, an effective utilization of the cache memory can be realized and the access speed can be improved so that it is faster.

Abstract: Where layered ignition elements with long delay times are concerned, malfunctions occur above all when aggravating secondary conditions (such as, for example, a high projectile rotation and/or temperature and shock stresses) are additionally involved. The reliable progress of the reaction is assisted if, as seen in the direction of propagation of the reaction, the middle region of the charge (8) igniting the delayed-action composition (3) projects into the middle region of the delayed-action composition (3). A further improvement can be achieved if, instead of an ignition charge (2), one or more transmission charges (7, 8) are interposed and the selection of the charge components is made in such a way that the jumps of the property values (especially as regards the reaction speed) become more uniform and therefore smaller, or an ignition charge having an especially low reaction speed is used.

Abstract: The present invention relates to the treating of fiber suspensions in the pulp and paper industry and particularly to a method and apparatus for washing fiber suspensions. 
     The method is characterized in that the fiber suspension is fed into the treatment apparatus, the desired process is carried out and the suspension is discharged from the apparatus in such a way that the fiber suspension is fed directly from the pipework to the treatment ducts mounted between the end plates of the rotational parts of the washer thus forming substantially extensions of the pipework. The fiber suspension is treated in the ducts and thereafter the treated suspension is discharged from the ducts by feeding yet untreated suspension to the apparatus. 
     The apparatus includes a plurality of axially elongated treatment ducts (9) arranged in the form of a ring around an axis of rotation. The ducts are radially limited by filter surfaces (10, 11) and in the direction of the end walls divided by partition walls (8). The ducts are rotatably arranged around shaft (12) inside casing (2). A feed conduit (4) for the pulp is arranged at one end of the apparatus and a discharge conduit (6) for the treated pulp at the opposite end thereof. The feed and discharge conduits are sequentially registrable with the same treatment duct.

Abstract: In heat pump installations which absorb the heat from the surrounding atmosphere, the transfer of heat from the air to the evaporator has been brought about, for design and process-engineering reasons, by using a brine as heat transfer liquid which absorbs the heat from the air in open contact and then delivers it to the evaporator. On contact with the brine, the atmospheric moisture condenses, with the result that the brine becomes diluted. The brine has now been replaced by a heat transfer liquid which is immiscible with water and which has a density differing from that of water, for example an oil. The condensed water can readily be separated from the heat transfer liquid in a stilling section, for example a settling tank. This enables constant operating conditions to be achieved. <IMAGE>

Abstract: The data communicating apparatus subdivides an information message into data blocks each having a predetermined length. When the number of data block transmission errors exceeds a fixed value, the data block to be subsequently transmitted (including a data block to be retransmitted) is further subdivided into small data blocks for the subsequent transmission. As a result, the error occurrence ratio is lowered and the data communication can be continued even under an unfavorable communicating condition.

Abstract: A divider for producing a quotient by dividing a dividend by a divisor has an A register (1) for holding dividend data, and a B register (2) for holding divisor data. An adder/subtracter or arithmetic unit (3) produces either one of a sum and a difference between the dividend data and the divisor data held in the A register (1) and the B register (2), respectively. A D flip-flop (4) holds sign bit data which is included in result data representative of a result of operation as produced by the adder/subtracter (3). An inverting gate (5) inverts the sign bit data. A shift register (6) sequentially shifts, every time the inverted sign bit data is inputted, the inverted sign bit data from the least significant bit (LSB) position while holding the inverted sign bit data. A shifter (7) arithmetically shifts the result data produced by the adder/subtracter (3) one bit to the left while storing a (logical) ZERO in the LSB position, and feeds the resultant data to the A register (1). A loop counter (8) controls the adder/subtracter (3), shift register (6) and shifter (7) such that iterative processing for division is repetitively executed.

Abstract: The invention relates to an optical emitter for electrical data signals, of an emitting diode, particularly a laser diode or light-emitting diode, with a bias current source, of a differential amplifier comprising two emitter amplifiers and a modulation current source and of a detector circuit, comprising a photodiode, for controlling the bias current and the modulation current proportional to the electrical data signal as a function of the optical pulses, received by the photodiode, of the emitting diode. The only thing that can be done with a known optical emitter of this type is that the mean optical emitting power (Pm) and the amplitudes (Ps) of the optical pulses can be kept constant. However, the duty ratio of the optical emitting signal changes, for example, as a function of temperature or of the supply voltage. To avoid these disadvantages, the invention provides that a peak value detection circuit (SES) and a controller (R) are inserted between the detector circuit (DS) and the differential amplifier (VD) and that the duty ratio (T1, T2) of the optical emitting signal (Sopt) of the emitting diode (LD) are kept constant as a function of the peak values (Up, Un), determined by means of the peak value detection circuit (SES), of the positive and negative amplitudes by means of the controller (R).
