Title: Dma controller
Inventor: KAWAKAMI YASUHIRO
IPC: G06F13/28
Filed: 1990-05-31
Abstract: PURPOSE:To transfer the data at a high speed without giving any load to a CPU by selecting sequentially the registers holding the page addresses to undergo the accesses and applying these selected registers to a memory as the high order addresses. CONSTITUTION:An address counter 34 generates the addresses in a page as the low order memory addresses, and plural page address registers RG0 - RGn-1 hold the addresses of plural pages to undergo the accesses with the DMA data transfer. Then a high order memory address selection means 30 selects alternatively the page addresses given from those page address registers in a prescribed sequence and outputs these selected addresses as the higher order memory addresses. In such a constitution, the data can be continuously transferred at a high speed even in a DMA data transfer mode for the discontinuous storage area. In addition, the CPU throughput is improved without giving any load to the CPU.

Title: Screen scroll controller
Inventor: HIRANO MOTOMIKI
IPC: G06F3/0485
Filed: 1995-06-09
Abstract: PURPOSE: To scroll a screen at a high speed without using a special memory. CONSTITUTION: In this screen scroll controller, a display ASIC9 is connected between a plotting memory 4 and a display memory 5. When scrolling is instructed by a joy stick 8a, a memory control circuit 9b inside the display ASIC9 judges whether or not the rewrite of the display memory 5 is required, and when it is not required, rewrites the screen just by changing the read start address of the plotting memory 4. On the other hand, when the rewrite of the screen is required, only data for performing rewrite are DMA(direct memory access) transferred from the plotting memory 4 to a FIFO(fart in fast out) memory 9c inside the display ASIC9 and then, the data of the FIFO memory 9c are read at a prescribed timing, stored in the display memory 5 and also transferred to a display control circuit 9c.  Thus, at the time of screen rewrite by scrolling, the screen is rewritten without reading the data of the display memory 5 and high-speed scrolling is made possible.

IPC: B41J11/70
Filed: 1983-08-08
Abstract: PURPOSE:To enable to make constant the length of a recorded rolled paper, by providing a means for detecting the feed quantity of the rolled paper and a means for recording a specified symbol or character for each predetermined paper feed quantity. CONSTITUTION:After feeding a paper by several steps, a controlling circuit 1 prints a dotted line used as a reference, and sets a counter circuit 3 into an initial state. Thereafter, the counter circuit 3 detects a paper-feeding signal (a) fed from the controlling circuit 1, and generates a carry signal when the counted content reaches a preset value. On detecting the carry signal, the controlling circuit discriminates that the paper has been fed by a predetermined length from the reference dotted line, then interrupts data printing being conducted, feeds the paper by a several-line amount, and prints a dotted line. Accordingly, since a specified symbol or character can be printed for each specified paper feed quantity, it is enabled to provide the rolled paper with a function of being a standardized paper or being regular in length.

Abstract: PURPOSE:To switch lighting or extinguishing of a lighting means, by a method wherein the presence of an operator is detected with a sensor as he approaches and a lighting means which irradiates light for automatic positioning is lit by the resulting detection signal. CONSTITUTION:When a sensor 4 detects the presence of an operator as he approaches near a bed, a signal S4 is outputted and supplied to an AND circuit 6 and a timer 5. As a result, when an inversion signal of the signal S3 and the signal S4 are supplied simultaneously, the AND circuit 6 outputs an AND signal S5. An OR signal 7 is determined between the AND signal S5 and a lighting command signal S6 of a manual projector 3 and thereafter, when a signal S7 is detected, a flop flip 10 outputs a lighting command signal S8 to the projector 3 to keep the projector on continuously. When the bed is not ready to be positioned or when a specified time passes after the detection of the presence of the operator with the sensor 4, or when a manual extinguishing command is inputted, the projector 3 is put off.
