Abstract: A method for the determination of the value of a property of the material within a mill during the comminution of solid material within the mill comprises the steps of:
     (a) detecting the noise intensity of milling by means of an analogue electrical signal, the intensity of which is proportional to the intensity of the noise in the audio frequency range, converting the analogue signal to a digital signal,   (c) passing the digital signal through a digital band-pass filter to select at least two frequency bands, and   (d) analysing the data from the bands by means of a multivariate statistical technique to obtain the value of the property. The method is particularly suitable for determining the particle size distribution of material being ground in a ball mill.

Abstract: In order to attain a frequency spectrum efficiency by narrowing channel interval without inducing interference from adjacent channels, a signal level of a mobile unit which requests channel access is detected at a land site. The signal level thus detected is used to assign a channel to the incoming mobile unit such that the assigned channel is adjacent to a channel whose signal level is closest to the signal level of the assigned channel. Further, in order to meet magnitude changes of received signals, the magnitudes are checked so as to reassign currently allocated channels.

Title: Data transmission system
Inventor: KOMIYA KAZUHIKO
IPC: G06F13/42
Filed: 1989-12-06
Abstract: A data transmission system is used between information processing devices (1,2) with dissimilar processing speeds. In this system, the transmission and reception of data is carried out on a data unit-by-date unit basis. Every time a lower-speed device (2) completes processing of the data, a signal representing the completion of processing is transmitted back to a higher-speed device (1) and, then, the reception of the next data unit takes place. In this arrangement, the data transmission interval agrees with the processing cycle in the lower-speed device (2), thus making it unnecessary to pre-set an unnecessarily long transmission interval with a reserve.

Abstract: A color image quantization system is described which utilises a look up table into which representative color data is loaded. This data is determined by repeated division of original color space into K child-color spaces, K being equal to the number of addresses to the LUT. The order of division is dependent upon the frequency of original image pels whose colors lie in each color space. Utilising the system, the number of pels assigned to each color space becomes as nearly equal as possible and image quality is maintained.

Abstract: A sheet storage case for storing therein a stack of sheets. The sheet storage case is assembled into a sheet feeding device which feeds out an uppermost sheet of the stack of sheets. The sheet storage case includes a bottom plate (101a), a first positioning member (102) fixedly secured to the bottom plate and a second positioning member (103) slidably movably provided in the bottom plate. The second positioning member has a sheet receiving portion (103c) for receiving the stack of sheets. The second positioning member is movable toward and away from the first positioning member. To mount a stack of sheet on the sheet storage case, the second positioning member is moved away from the first positioning member, the sheets are placed on the sheet receiving portion, and then the second positioning member is moved toward the first positioning member. The side edges of the sheets are aligned, because the sheets are fittedly interposed between the two positioning members. The uppermost sheet is taken out by a mechanism which includes a suction cut which is brought to contact with the uppermost sheet to attract the latter. The suction cup to which the sheet is attracted is swung in the position above the sheet storage case to separate the upper­most sheet from the reminder.
