Title: Reservation system
Inventor: TAKAHASHI HIROKO
IPC: H04J3/00
Filed: 1980-08-14
Abstract: PURPOSE:To increase the line utilization rate, by giving the slot reservation number of priority, slot using number in the next frame, and slot reservation number of ordinary class to the reservation burst transmitted from a plurality of earth stations of a satellite communication line. CONSTITUTION:The communication line of a communication satellite 1 and earth stations 2-4 is constituted with incoming channels 5-7 and an outgoing channel 8. Each earth station transmits reservation bursts 12-14 in time division. The reservation bursts are transmitted with a priority slot SL reservation number 21, priority SL number 21 requesting the SL assignment of the priority class actually in the next one frame, and ordinary SL reservation number 23. The earth station 2 assigns received bursts 12-14 from the channel 8 from the head SL in one frame by sequentially checking the priority SL using number 22 of each earth station. Next, the assignment of the ordinary class SL is made with the priority. Thus, even with the SL reservation of priority class, if an SL not transmitting data burst is present, the transmission of the data burst of ordinary class can be made, allowing to use lines without waste.

Title: Fabricating method of fine groove in inside surface of u-pipe
Inventor: UEHARA KATSUJI
IPC: B21H8/02
Filed: 1978-09-14
Abstract: PURPOSE: To eliminate the decrease in the pressure resistance strength of pipe and perform the captioned fabrication surely by partially restraining the specified outside circumferences of the U-pipe with cylindrical collars of the inside diameter approximately the same as the outside diameter of the pipe, pushing thread-rolling tools into the pipe and rolling the tread surface shape of the rolling rings on the inside surface of the pipe.  
     CONSTITUTION: The portions of a U-form pipe except its end parts 2 and bend part 3 are restrained by cylindrical collars 8 of the inside diameter slightly larger than the outside diameter of the pipe and the thread-rolling tools 4 provided with multiple rolling rings 5 to cylindrical holders 6 are mounted to the end of rods 7 and the tools 4 are pushed into the pipe 1 by way of the rods 7. Since the tools 4 are integrally coupled with the rods 7, they advance while rotating, thereby forming multiple fine grooves having helix angles of around 10° parallel to the central axis direction of the pipe 1 or in its axial direction on the inside surface of the pipe. When the ends of the tools 4 reach the left end of the collars 8, pushing of the rods 7 is stopped and the rods are pulled backward, then the tools 4 are removed while rotating along the grooves formed and therefore collapsing of the grooves does not occur.

Title: Picture processor
Inventor: DOI HIROSHI
IPC: G06T3/00
Filed: 1984-06-01
Abstract: PURPOSE:To detect accurately a picture of a prescribed form without requiring complicated processing by using an approximation circuit that applies the approximation processing to the picture into a prescribed form based on the contour data obtained from a contour extracting circuit. CONSTITUTION:A variable density picture obtained by photographing and inputting to a picture through a camera 1 is binary coded by a binary coding circuit 2 and stored to a memory circuit 3. For this binary coded picture, the pairs (x1, y) and (x2, y) of contour points are extracted by a contour extracting circuit 4 to satisfy conditions (x1-1, y)<(x1, y) and 1(x2, y)>1(x2+1, y). Then a square approximation circuit 6 performs the following approximation. In case the contour points adjacent to each other at upper and lower parts of the same pattern satisfy x1-x3<=DELTAx and x2-x4<=DELTAx, it is judged that four points (x1, y), (x2, y), (x3, y+1) and (x4, y+1) are included in the same square, where DELTAx is equal to the threshold value of approximation. If DELTAx is equal to a picture element, for example, a binary coded pattern is approximated to two squares 7 and 8.
