Abstract: PURPOSE:To detect an absolute position with high resistance against noise with high accuracy by detecting a light source beam radiated from a movable body divided by a beam splitter and reflected light reflected by a reflecting plate having the distribution of reflection factors and executing the calculation of a position. CONSTITUTION:An optical beam radiated from a light source 2 on the movable body 1 is divided into two beams by the beam splitter to be moved integrally with the movable body 1, one beam is photodetected by a photosensor 5 and the other is transmitted through the splitter 3, reflected by the reflecting plate 7 having the distribution of reflective indexes through an optical lens 6 and photodetected by a photosensor 9 through the splitter 3 and so on.

IPC: G06F13/28
Filed: 1986-10-13
Abstract: PURPOSE:To ensure instantaneous transfer of produced data by adding simple hardware to a direct memory access DMA controller. CONSTITUTION:A transfer control circuit 4 performs a DMA transfer job by the request signal set on a transfer request signal line 8 and gives +1 to an address counter 5 for each DMA transfer with -1 given to a word line counter 6 respectively. A produced data address counter 1 receives a DMA start address set via a bus 10 prior to the DMA transfer and then receives +1 by the signal received from outside and set on a transfer ready signal line 9. A comparator 2 compares the contents of the counter 1 with those of the counter 5 and delivers the result of this comparison to the circuit 4. The circuit 4 inhibit the DMA transfer action when the output of the comparator 2 is equal to zero and then holds a transfer request if received. While the circuit 4 performs a prescribed transfer action in response to a transfer request when the output of the comparator 2 is not equal to zero.

Abstract: PROBLEM TO BE SOLVED: To suppress switching while a bus line is being used and to save the power. SOLUTION: A driving means 11 driving the potential of a signal line 10 in accordance with an arbitrary binary logic signal in terms of binary, a detection means 11c detecting the frequency of the logic change of the binary logic signal and conversion means 11a generating the NOT signal of the binary logic signal when frequency exceeds a prescribed value and giving it to the driving means 11 instead of the binary logic signal are provided. When the frequency of the logic change of the binary logic signal exceeds the prescribed value, the signal line 10 is driven by the NOT signal of the binary logic signal. For example, when logic '0' is changed into logic '1', it is expediently explained by the logic signal of one bit, the signal line 10 is driven by the NOT signal of changed logic '1', namely, by logic '0'.  The driving logic (logic '0' in such case) of the signal line 10 is similar to logic before a change. Thus, the signal line 10 is not substantially switched and power can be saved.

Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To efficiently accelerate the dehydration of a byproduct from the production of food such as bean-curd refuse and to considerably increase the rate of dehydration by mixing the byproduct with yogurt or discarded yogurt. SOLUTION: When a byproduct from the production of food such as bean- curd refuse is dehydrated, yogurt or discarded yogurt is necessitated to coexist with the byproduct. More effective dehydration is carried out by mixing them as uniformly as possible. A material (e.g. lees of low-class distilled spirits) similar in physical properties to yogurt may also be used. Yogurt or discarded yogurt well produces its effect when 1 pt.wt. beancurd refuse is mixed with about 0.5-5 pts.wt., preferably about 1-3 pts.wt. yogurt or discarded yogurt. Combination with electroosmosis is more effective.
