Filed: 1985-10-03
Abstract: PURPOSE:To make inertia load at times of starting and stopping reducible, by forming a bypassing part of paper between roll paper and a feed roller by a difference in acceleration at the time of stoppage, and at the time of starting, making the number of sheets of paper between both so as to be decreased within the range that the bypassing part completely vanishes away. CONSTITUTION:As for acceleration till rotation or paper feed speed comes to be con stant, since output of a roll paper shaft driving motor 23 is being set so as to make the side of roll paper 1 smaller than that of a feed roller 2, paper is reduced between the roll paper 1 and the roller 2, while a movable guide plate 4 rotates counterclock wise. Next, the paper between the roll paper 1 and the roller 2 is conveyed forming a bypassing condition by forcibly pressing by the guide plate 4 at an angle theta2, and during this while, when is produced variation in paper quantities between the roll paper 1 and the roller 2 due to variations in a rotary variable resistance 10 or the like to be connected to an arm 1, the guide plate 4 turns round and thereby a roll paper revolving speed is increased or decreased in relation to the turning value, thus the guide plate 4 returns to the angle theta2. Then, as for the acceleration ranging from deceleration starting to stopping, motor output is set so as to make the side of the roll paper 1 smaller, thus slip is prevented.

Filed: 1989-08-26
Abstract: PURPOSE:To prevent a circuit current from being reactively consumed by providing a high recombination ratio region at a part of a collector or base region of a vertical npn Tr of a drive Tr of a SRAM. CONSTITUTION:Since Trs Q1, Q3 are ON and collector regions (semiconductor layers 2, 3, 9) and base regions (diffused layers 3, 7) are biased forward therebetween, injection of minority carrier occurs. The density of the minority carrier is high in the relatively low impurity concentration regions 3, 4. Since a high recombination region by a p<-> type polycrystalline silicon layer 12 is formed near an emitter electrode E3 of a p<-> type diffused layer 4 of a base region, recombination of the minority carrier occurs in this part, and the concentration of the minority carrier in the vicinity of this part is reduced. As a result, the number of carriers to be absorbed to the electrode E3 in which a reverse bias is applied is reduced, and an unnecessary power consumption is eliminated.

Title: Direct memory access controller
Inventor: NAGAI HAJIME
IPC: G06F13/28
Filed: 1987-09-01
Abstract: PURPOSE:To delete a control code out of the transfer data with no intervention of a CPU, by producing the read signal of an I/O and the write signal of a main memory after the acceptance of a DMA request. CONSTITUTION:When a DMAREQ signal is supplied to a timing generator 3 from the I/O for request of the DMA transfer, a HOLDREQ signal is produced to a CPU for the request of application of a bus line. When the CPU approves said request, the CPU sends back a HOLDACK signal and the generator 3 outputs a DMAACK signal to the I/O. Then the generator 3 sends a read signal R to the I/O and the I/O outputs the data to a data bus. This data is compared with a control code via an associative memory 1 for the output of a coincidence signal. The write signals produced from the generator 3 and supplied to gates circuits 4 and 5 so that the updating is stopped for a counter 2 which produces the write address of a main memory. Thus the control code is deleted out of the data written into the main memory.
