Abstract: PURPOSE:To obtain a small-sized copying machine suitable for personal use by constituting it so that a recording information of an image or a character read by an original read system is transmitted directly to a recording head, and printing the image or the character on an ordinary paper in the direction opposite the direction of reading the original based on data from an image sensor. CONSTITUTION:A recording information read by the image sensor 15 is transmitted directly to the recording head 49 as data for a recording system, and this head 49 prints on a recording paper 10 which is an ordinary paper based on said data. Therefore, a central controller is made unnecessary to be, and the constitution of a control part is simplified. Also, the original reading direction of the sensor 15 and the recording direction of the head 49 are made opposite to each other; the original 9 and the recording paper 10 are so disposed that the former's surface to be read and the recording surface of the latter face each other; the sensor 15 and the head 49 are supported by a common guide shaft 43. In such a way, the entire body of the titled copying machine can be minizturized.

Abstract: PURPOSE:To prevent securely the leakage of silica, etc. into the demineralized water by comparing the difference between the estimated time when the reference value at the part between the weakly basic anion-exchange resin and the strongly basic anion-exchange resin is exceeded and the time when the reference value is actually exceeded. CONSTITUTION:The total amt. of the components to be removed can be obtained on the basis of the permittivity C1 and the flow rate F of the original water by obtaining previously the relationship with the electrical conductivity from the provious water quality measurement. The ion-exchange capacity of a weakly basic anion-exchange resin 5 and a strongly basic ion-exchange resin 6 can be previously obtained. The time when the C2 exceeds the reference value due to the leakage of the anion from the weakly basic anion-exchange resin 5 can be calculated on the basis of said ion-exchange capacity and the load of the orginal water. The time when the C3 exceeds the specified electrical conductivity of the water quality can be calculated in the same way, and the time when the intake of the water is finished can be obtained by multiplying a safety factor to prevent the leakage of silica into said time.

Title: Heat exchanger
Inventor: KAMISAKA MITSUO
IPC: F28D1/047
Filed: 1984-02-22
Abstract: PURPOSE:To improve heat transfer characteristics and make the heat exchanger compact by a method wherein ascending parts, in which heat transfer performance is not favorable, are reduced and descending parts are increased in the heat exchanger, in which fluid in the tube repeats ascending motions and descending motions. CONSTITUTION:Both ends of the heat transfer tube 1 are provided with headers 2 while fins are provided between neighboring heat transfer tubes. Fluid in the tube flows into the direction of the arrow sign 5 in the diagram along the heat transfer tube while external fluid flows into the direction of the arrow sign 4 orthogonally to the heat transfer tube. The lengths of the descending parts 1A are made longer than the same of the ascending parts 1B in the heat transfer tube. Internal fluid contacts with the external fluid by the length L of descending flow 7 in the descending part 1A while the ascending flow 8 of the internal fluid contacts with the external fluid by the length l in the ascending part 1B while the relation between the lengths is L>l, therefore, heat exchange is effected much more in the descending part 1A and the condensation as well as the liquefying of the internal fluid can be increased. Accordingly, excellent heat transfer characteristics may be obtained, the length or the number of the heat transfer tube may be reduced and compact and inexpensive heat exchanger having a high performance may be obtained.

Title: Carrier of developed coil of wire material
Inventor: MATSUNAMI AKIRA
IPC: B65G13/08
Filed: 1981-03-05
Abstract: PURPOSE:To prevent a coil from slippliig and enable to carry the coil on a line accurately by providing a tapered roller with its both tapered ends expanded on a curved passage of a roller table carrier for a developed coil of wire material in its cooling process. CONSTITUTION:Diameters for both a small and a large ends d1 and d2 of a tapered roller are increased to d1' and d2' for forming duplicate taper respectively. After this roller is provided on a curved carrier passage for carrying a coil, if the coil is slipped out of a C3' side of the exterior circumference of the curved carrier passage, a speed given to the coil circumference by the larger circle d2' of concentric circles becomes faster than the one given by the smaller circle d2 of the normal taper roller as d2' is larger than d2, then an advance direction of the coil is corrected to the interior circumference C1' of the curved carrier passage having a small curvature. On the contrary, if the coil is slipped out of the C1' side, the advance direction of the coil is corrected to the exterior circumference C3' of the curved carrier passage having a large curvature. Then the coil can be carried smoothly without slipping out of the center of a roller table.

IPC: G01M1/38
Filed: 1981-03-03
Abstract: PURPOSE:To correct errors owing to the run-out of rims in the radial direction by measuring the run-out of revolutions of the rims prior to mounting of a tire to be inspected and multiplying the rates of run-out of the revolutions by the spring constant of the tire thereby determining error quantity. CONSTITUTION:An upper rim 4 and a lower rim 21 without mounted with a tire (a) are coupled by the engagement of a mounting seat 7 and an elevating shaft 24, and are revolved. The rates of run-out in accordance with the revolutions are detected with respective run-out detectors and are stored. Next, the tire (a) is mounted and is revolved. The phase angles of the base points of the rims 4, 21 are detected and the signal for the rate of run-out of the lower rim 21 outputted from the storage circuit is corrected. The corrected signal for the rate of run-out of the rim 21 and the signal for the rate of run-out of the upper rim 4 are added and averaged respectively. Only the primary component waveform of the waveforms is extracted by a harmoric analysis circuit, and is multipled by the spring constant of the tire. This correction signal is subtracted from the fluctuation signal of the force in the radial diretion of the tire (a) from a load cell 34, whereby the influence components of the errors by the run-out of the rims 4, 21 are removed.

Title: Measuring device of radioactivity nuclear species
Inventor: GOTOU TETSUO
IPC: G01T1/17
Filed: 1983-02-28
Abstract: PURPOSE:To calculate accurately the amount of radioactivity in a sample by making corrections on the basis of the relation previously found as to a total counting rate and a death time and the variation found by performing counting at every unit time by utilizing a multiple counting rate. CONSTITUTION:A multiple counting system 16 calculates the variation in total counting rate during a measurement of the sample 11. Namely, when the measurement of the sample is started, only the detection signal of gamma rays is supplied to a multiple counting circuit 162. Then, the total counting rate N in the sample measurement is found at every unit time and written in a process memory 163. A multiple crest value analysis system 17, on the other hand, calculates the peak counting rate of the gamma rays from gamma-ray radiating nuclear species. When the measurement is completed, a computer 18 for data analysis reads data out of process memories 163 and 172 and obtains information on the correction coefficient of the death time from the memory 163. Further, peak counting rates by nuclear species are obtained from the memory 172. Then, the correction coefficient is calculated from the variation in total counting rate. Thus, the correction coefficient is calculated to make corrections, thereby calculating accurately the amount of radioactivity in the sample.
