Title: Data transfer system
Inventor: KISHIGAMI SHINJI
IPC: H04L69/40
Filed: 1987-06-15
Abstract: PURPOSE:To realize the apparent simultaneous progress of programs for a central processing unit CPU of a host computer by releasing a holding request signal of the CPU for each transfer of data. CONSTITUTION:When DMA transfer is carried out to a host computer 11 from a monitor 10, a CE signal S1 whose address is decoded is active by a command of a CPU 27 and then a MREQ signal S2 is active. At the same time, flip-flops 51 and 52 are actuated to transmit a WAIT signal S3 to the CPU 27 and a holding request HRQ signal S4 to a memory 11b of the computer 11 respectively. Thus the memory 11b sets a bus 35 at a high impedance to release it and at the same time the memory 11b itself is interrupted in a WAIT state. While the monitor 10 is unable to perform the DMA transfer as long as a memory 11a of the computer 11 is kept under a refresh state. When the refresh state of the memory 11a is ended, the buffer gates 57-59 are opened and single memory access is carried out.

Title: Cleaning device of bath tub hot water
Inventor: MISHIMA FUMIYUKI
IPC: C02F1/28
Filed: 1994-06-07
Abstract: PURPOSE:To provide a simple and inexpensive bath tub hot water leaning device which effectively executes back washing of filter media and is intensified in a bubble bath effect. CONSTITUTION:An air tank 14 is disposed in the circulating path of hot water on the downstream side of a filter tank 5 packed with the filter media. A circulating pump 6, then a selector valve 17 are disposed at a hot water suction pipe 3 and a selector valve 19 is disposed at a hot water gushing pipe as well. A hot water discharge pipe 18 is connected to the hot water suction side selector valve 17. The hot water suction pipe 3 and the hot water gushing pipe 9 are directly connected by a bypass pipe 20 via the selector valves 17 and 19. As a result, the filter media are back washed together with the air accumulating in the air tank 14 and are, therefore, effectively back washed in a loosened state. Strong jet flow is ejected into a bath tub when the hot water is passed through a bypass pipeline directly coupling the hot water suction pipe and the jet hot water pipe which does not pass the filter tank having the large resistance to the hot water flow. The effect as the bubble bath is thus enhanced.

Abstract: PURPOSE:To perform highly accurate postioning of a head by a simple consitution, by using the same material for a light transmitting scale, on which a pattern with a constant pitch indicating position data is recorded as the material of a recording medium, and absorbing thermal offset. CONSTITUTION:A main scale 6 is formed by a light transmitting guide scale 10, on which a pattern with a constant pitch corresponding to the position data of a head is recorded, and a substrate 11, whose material is the same as that of a magnetic disk. Therefore the thermal expansion of the scale 6 and that of the magnetic disk are the same. Thermal offset due to temperature change and the like is absorbed. the scale 6 is read by a transmitting intensity detector 7 comprising an index scale 12 and a light receiving device 13, which is moved together with the head, and a light emitting device 8. Thus highly accurate positioning of the head can be performed without the effect of the thermal offset by a simple constitution.
