Patent JP-S57172404-A (JP)
Title: Driver for controller
Inventor: SHIMIZU YUUJIROU
IPC: G05B11/36
Filed: 1981-04-15
Abstract: PURPOSE:To drive a controller while improving hysteresis characteristics without adding a position sensor by sending a correction signal, generated by adding a command signal to a signal from a function generator, to the controller. CONSTITUTION:When a command signal X1 is inputted from a command device 1 to the 1st register 2, the register 2 stores the X1 and outputs a signal R1=X1. In this case, the value R2 of the 2nd register 3 is 0, so the output C of a subtracter 4 is equal to the X1 and inputted to a function generator 5. Since C=X1, namely, C>0, the generator 5 sends a signal (a) as its output (d) to an adder 6, which adds the (a) to the command signal X1 by e=R1+d to output a correction signal (e). It is amplified by a factor K at an amplifier 7 to input a signal I=K(X1+a) to a stroke valve, thus obtaining a storke signal y=Y1. Consequently, the relation between the command signal (x) and the amount of a stroke is varied according to ideal characteristics to remove the influence of hysteresis.

Title: Low-temperature show case
Inventor: NAGANUMA HIROSHI
IPC: F28D15/02
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To lessen the temperature difference between the accommodated substances by the side of a refrigerator room wall and the accommodated substances away from the refrigerator room wall, and equalize the temperature difference in the goods in the refrigerator quickly, by annexing a heat pipe to a middle partition plate, in a low-temperature show case which is equipped with a middle partition plate in the refrigerator room. SOLUTION: A low-temperature show case used for the sale of ice cream or the like has a heat insulating box, and the refrigerator room is provided with a middle partition plate 13 to partition the refrigerator room. At this time, the partition plate 13 is provided with a heat pipe 15, and the inside is charged with working fluid from a pinch part 17. For this heat pipe 15, when a temperature difference occurs in this, the working fluid evaporates on the side where the temperature is high and it separates from the interior, and at this time, it robs the ice cream on high temperature side of latent heat for evaporation.  Then, the evaporated working fluid shifts to the low-temperature part, and it gives heat for liquefaction to the ice cream which is condensed and cooled at the face low in temperature, and functions to dissolve the temperature difference by repeating the cycle of liquefaction.

Abstract: PURPOSE:To enhance the latchup withstanding property by providing a memory cell in a low specific resistance region, and forming a peripheral circuit element in a high specific resistance region, thereby preventing a memory cell for inducing minority carrier due to alpha-ray and impact ionization from erroneously operating. CONSTITUTION:A memory cell is formed in a well 9 of a low specific resistance in opposite conductivity to a substrate, and a peripheral circuit element is provided in a well 10 of a high specific resistance in opposite conductivity to a substrate. Thus, the memory cell has large P-N junction capacity in the well 9 of the low specific resistance and large storage capacity of memory cell. Thus, software error hardly occur due to alpha-ray, and the substrate of a parasitic PNPN transistor and the potential of the well are suppressed in variation in the same current amount as the well potential to cause a latchup withstand voltage to become high, thereby increasing the latchup current as the entire semiconductor memory. On the other hand, a peripheral circuit element is disposed in the well 10 having small P-N junction capacity. Thus high speed operation can be performed.

Filed: 1978-05-18
Abstract: PURPOSE: To enable the shapes of strip form patterns to be known intuitionally and make the judgement of goodness or not of the shapes by expressing the strip shape patterns in terms of parameters indicating the differences in the rates of elongation to the center of the strip.  
     CONSTITUTION: Shape detectors 1 are provided in a plurality by leaving their detecting ends 2 therebetween and are disposed orthogonally in the strip pass direction R so as to detect the shape in the width direction of a strip S. The detecting ends 2 detect the rates of elongation at the respective points in the width direction of the strip S, output these as shape signals, and input these shape signals into a shape signal input unit 3. Based on the shape signals of the shape signal input unit 3, an electronic calculator 4 calculates parameters expressing the rates of elongation for the strip center. Hence, the shape is intuitionally known by the magnitude of the absolute values of the values of these parameters and positive and negative codes; in addition the goodness or not of the shape thus detected may be readily judged.

Title: Data processor

IPC: G06F9/445
Filed: 1993-03-18
Abstract: PURPOSE:To shorten time required for setting initial setting data to memory parts at a lot of POS terminals and to reduce the burden of a host computer. CONSTITUTION:When the clown loading of setting data is selected, a host computer HC transmits the previously stored setting data to POS terminals TM1 and TM2' designated as most significant terminals and waits for normal load end responses from respective POS terminals TM7-TM14 designated as least significant terminals later. When the responses are received, the down loading of the setting data is finished. On the other hand, when the setting data are received, respective POS terminals TM1-TM14 store those setting data in the memory parts and judge the presence/absence of terminals in lower-order layers rather than those terminals. When there are terminals in the low-order laters, the terminals TM1-TM6 transmit these setting data to the POS terminals in the low-order layers and when there is no terminal in the low-order layer, the terminals TM7-TM14 transmit the normal load end responses to the host computer HC.

Abstract: PURPOSE:To prevent poor detection and disabled detection, by forming a number of grooves on either of opposed surfaces of a cylinder and a moving body. CONSTITUTION:As a fluid flows in at a fluid inflow port 1, by a pressure of the liquid, a moving body 8 moves compressing a spring 9 and passes the position of a hole 10 and by this, a lead switch 12 detects that a fluid flows with the fluid inflow port 1 running into the hole 10. When liquid with a high precipitating property such as developer and fixing liquid used in a photosensitive processor is left alone for a relatively long time as retained in a clearance at least between the inner surface of a cylinder 4 in a galvanometer and the outer surface of the moving body 8, a groove 14 formed on the outer surface of the moving body 8, namely, a case 6 eliminates clinging therebetween with the fluid resistance too much in the inner surface of the cylinder 4 though precipitation takes place at this part. This can prevent poor detection and disabled detection.
