Patent EP-0262429-A2 (EP)
Inventor: SAITO SAYURI C O NEC CORPORATI
IPC: G06F15/17
Filed: 1987-09-01
Abstract: A transmitting data processor comprises a data processing unit for supplying a predetermined length of data to be transferred and generating a transfer start signal, and a data transferring unit receiving the predetermined length of data to be transferred from the data processing unit and for transferring the predetermined length of data in a serial form to a receiving data processor. The transmitting data processor also includes a busy detector for detecting a busy signal from the receiving data processor, a register for temporarily holding the transfer start signal from the data processing unit, and a start controller associated to the data transferring unit for causing the data transferring unit to stop the transfer of data during the period the busy signal is active and for allowing the data transferring unit to start the transfer of data when the busy signal becomes inactive after the transfer start signal is generated. 
     The receiving data processor includes a data receiving unit for receiving the predetermined length of data transferred from the transmitting data processor, and a data processing unit coupled to the receiving unit for processing the received data and generating a transfer acknowledge signal when it has completed the processing of the received data. The receiving data processor also includes a busy signal generator for generating the above mentioned busy signal in response to completion of reception of the predetermined length of data and making the busy signal inactive when the transfer acknowledge signal is generated.

Abstract: A vertical wet stirred ball mill (21) is provided according to this invention, wherein a slurry raw material fed from the top of the mill body is stirred together with a grinding medium in said mill body under pressure and the material is gradually exhausted from the bottom of said mill body as it is milled. A spring-loaded conical separation valve (22) is fitted at an exhaust port of said body. The separation valve (22) retracts when the pressure within the mill body is increased due to plugging, thereby the annular clearance around the separation valve is enlarged to increase the amount of exhaust, leading to elimination of the plugging.

IPC: G01R13/20
Filed: 1987-11-02
Abstract: Disclosed is a method (Fig. 6, Fig. 7) for determining and executing the minimum number of sample acquisition-sweeps necessary to meet the risetime specifications (Table 1) of a digital oscilloscope (5) which uses random repetitive sampling. The method of the present invention selects from two criteria to determine the required number of acquisition sweeps. At narrow time ranges a risetime criterion (Table 2) is used. At wider time ranges a percentage-filled criterion (Table 3) is used. The choice between criteria depends upon the user-­selected time range setting. The time range setting directly affects the time-width of each one of a fixed number of time-buckets. A time-bucket (125) is a discrete unit of time which varies directly with the time-width of the user-selected time range. The number of time-buckets is fixed. Time-buckets can be manifested either on the oscilloscope display screen (10) or in the oscilloscope's memory (90). At time range settings where the time-width of each time-bucket is less than or equal to one-half of the risetime of the oscilloscope, the risetime criterion applies and ensures, prior to display of a waveform, that there is at least one sample point for each risetime-unit of time throughout all the time-buckets. At time range settings where the width of each time-bucket is greater than one-half of the risetime of the oscilloscope, the percentage-filled criterion applies and ensures, prior to display of a waveform, that a certain percentage of the time-buckets have been filled with sample point data. The minimum number of acquisition-sweeps necessary (Table 1), using either the risetime or the percentage-filled criterion, is determined using a binomial probability formula (Formula (2)).

Abstract: The invention relates to a friction surface comprising a conventional foil (1), such as paper or plastic foil, and hot melt bulges (2) and pattern formed by them made on the foil surface by a screening technique. The foil (1) chosen to be used should be such that it is most suitable for the specific package, but the thickness of it should preferably be more than 35 mm and it should at least temporarily endure the heat of about 140 - 180° C, which the hot melt has. The bulges made of hot melt are most advantageously made 50-150 µm high, whereby their ability to adhere to other surfaces is excel­lent. By using filling materials of the hot melts the friction can be increased even more, but in such cases normally thicker basic foil has to be used so as to prevent the foil from tearing. By using a friction surface, considerably high piles of packages can be made. Because the hot melt can be remelted, the top packages can be bound together by spreading any kind of foil on them, which can be attached on the friction surface by heating.

Abstract: An electric brake device for a centrifuge driven by an electric motor (10) is proposed, in which the electric motor (10) can be short-circuited in braking operation by a switching device (22). In this arrangement the exciter winding (20) of the electric motor (10) is connected to an electric supply device (17) which generates a current in the exciter winding (20) which is inversely proportional to the speed of the electric motor (10). As a result, as the speed falls the field current of the electric motor (10) rises so that, despite the decreasing induced voltage in the armature (23), a high braking torque is maintained virtually until the electric motor comes to a standstill, enabling even and rapid braking. <IMAGE>
