Title: Skin pass mill
Inventor: SATOU TATSUHIRO
IPC: B21B1/22
Filed: 1979-09-28
Abstract: PURPOSE:To make the traveling force of the metallic strip possible to always effectively rotate the work roll, by omitting the driving system for equalizing the circumferential speed of the work roll to the traveling speed of the metallic strip, in order to dissolve the power loss due to the inertial and friction force of the driving system. CONSTITUTION:When the weld zone of the metallic strip 1 is passed through the skin pass mill, the moving side work roll 3 is displaced by the action of the pressure mechanism 7. As a result, the gap of the work rolls 2,3, is widened, and at the same time, the unclipping roller 20 and the billy roller 21 press the strip 1 to the rolls 2,3, so as to wind around the rolls 2,3. Accordingly, the upper and lower rolls 2,3, always make contact with the strip 1 in a large contact surface even during the shutdown period of the rolling work; hereby, the rolls 2,3, rotate with the circumferential speed equal to the traveling speed of the strip 1 owing to the traveling force of the strip 1. Hereupon, the backup rolls 5,6, are also rotated through the rolls 2,3.

Title: Fishhook
Inventor: OKADA NAOKI
IPC: A01K83/00
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a fishhook which is scarcely liable to dehook a fish without disposing a barb and hardly detaches a bait. SOLUTION: This fishhook is made by connecting a slip-off stopper 3 to the shank 2a of a hook body 2. The tip portion 9 of the slip-off stopper 3 is placed at a place near to the point 2d of the hook body 2, but can elastically be displaced toward the side of the shank 2a. When a fish 5 bites the fishhook 1, the slip-off stopper 3 is pressed with the mouth of the fish 5 to displace the tip of the slip-off stopper 3 to the shank 2a. The mouth tip of the fish 5 passes between the shut-off portion 36 of the tip-off stopper 3 and the point 2d, and the slip-off stopper 3 is then returned to the original position. Thus, the mouth tip of the fish 5 is placed in a region surrounded by the hook body 2 and the shut-off portion 3b.

Title: Dma transfer queue matrix control system
Inventor: SHIMADA NORIO
IPC: G06F13/28
Filed: 1985-06-08
Abstract: PURPOSE:To minimize a waiting time by checking whether a DAM transfer is executed or not the moment an interruption from each channel is applied and starting the next DMA transfer when the normal termination of the DMA transfer in the middle of execution is recognized. CONSTITUTION:When an initial transfer request I from a channel is present, a central processing unit executes pre-processing for transfer with the aid of a microprogram. At this time when the DAM transfer is checked tr be executed or not, the DMA transfer is not executed, immediately the transfer processing I is executed. When a transfer request II arrives during said transfer processing, the central processing unit executes pre-processing, and connects the transfer request II to a queue matrix. When the transfer processing I ends, the central processing unit executes termination processing with respect to the transfer processing I, and simultaneously checks whether or not the transfer processing I terminates its action normally. After the checking is made, the central processing unit refers to the queue matrix to find a desired request, and then starts immediately the transfer processing II.

Abstract: PURPOSE:To shorten processing time end also to make it possible to use IC that provides low-speed, low-power-consumption operation, by prescribing the prediction coefficient of prediction DPCM of higher order. CONSTITUTION:Among coefficients of prediction function P(Z) (formula I) shown by Z transform, coefficient A1 of Z<-1> is set to zero. Then, coefficient A2 of Z<-2> takes a number given by A2=+ or -2 + or -2<m>+ or -2<n> (where l, m are integers - or infinity ) expressed by the sum of and difference between power exponents of ''2''. Thus, multiplication of prediction coefficients is replaced by a place shift, addition and  subtraction. Thus, the prediction coefficient is prescribed, so that the allowable  time of the coding loop of DPCM can be equalized to two sampling periods. Further, calculation of prediction coefficient A2 by prediction device 205 uses an adder- subtracter without using a multiplier, shortening the processing time. Additionally,  the circuit can be formed of low-speed, low-power-consumption IC.
