Title: Heat exchanger
Inventor: KURACHI SHIYOUGO
IPC: F28F9/14
Filed: 1979-10-12
Abstract: PURPOSE:To make the manufacture of a heat exchanger easy and increase its endurance by forming a collar having a ring groove to a header plate of a solderless heat exchanger for a car radiator or the like and connecting a tube to this collar by widening a diameter thereof. CONSTITUTION:A header plate 5 is placed on each end of a laminated body of plate fins 2. A tube 1 is inserted into holes 2a and 5a of the plate fin 2 and the heat plate 5 and then the tube 1 is widened at its diameter with a jig and fixed to the inner surface of the collars 2a and 5a of the fin 2 and the header plate 5 with pressure. Since U type ring groove 5b is mounted around the outer circumference of the collar 5a, a stress caused by an elastic transformation of the groove 5b acts on a combined surface A of the collar portion 5a with the tube 1, whereby a large surface pressure acts on the whole combined surface and a close and strong contact is obtained. Further, a mechanical load from outside can be absorbed by the transformation of the groove 5b, and therefore the endurance increases.

Title: Automatic chemical injection device
Inventor: AKAMATSU TATSUO
IPC: B01F15/04
Filed: 1989-05-25
Abstract: PURPOSE:To improve injection efficiency by providing a flow meter, a pair of two-way valves, a control means, a feed pipe, and a pressure drive quantitative pump, and providing a constitution of injecting a chemical into a feed main pipe followed by spraying. CONSTITUTION:When the flow rate of a feed main pipe 8 is reached to a preliminarily set flow rate integrating value, a flowmeter 1 transmits a detection signal to a control means 4. The control means 4 transmits a control signal for opening a first two-way solenoid valve 2 to the valve 2, whereby discharge stroke is started. In the discharge stroke, the valve 2 is opened, and a pressure fluid such as water or air is sent into a pressure drive quantitative pump 6, and a chemical is injected into the feed main pipe 8 through a feed pipe 5. When the discharge stroke is terminated, the control means 4 transmits a control signal for closing the valve 2 to the valve 2, whereby suction stroke is started. In the suction stroke, the valve 2 is closed, and the pressure added to the pump 6 is released. In this case, as a second two-way valve 3 is in the opened state, the pressure fluid is exhausted to the outside, and the chemical is sucked into the pump 6. The time ratio of both the strokes is set in the means 4.

Title: Damping water composition for lithographic printing
Inventor: MAEDA KAZUTAKA
IPC: B41N3/08
Filed: 1989-05-25
Abstract: PURPOSE:To impart printing suitability the same as IPA-based damping water, to improve printing environments and to reduce the damping water by employing a damping water composition for lithographic printing obtained by mixing a glycol ethers, specific water soluble high polymer compounds and dissolving them in water. CONSTITUTION:Damping water composition for lithographic printing is a mixture of a glycol ethers diluted with water at an optional rate, acid or salts, water soluble high-polymer compounds and water. In this damping water compound, hydroxyl propylene starch is used for a water soluble high-polymer compound. Hydroxyl propylene starch with a hydroxyl propylene group substitution degree of 0.12 to 0.15 is preferable. If the degree is below 0.12, the swelling dissolution of hydroxyl propylene to a glycol ether group or its dissolution is insufficient, whereas if the degree is over, the dissolution of hydroxyl propylene to water is liable to be insufficient. The content of hydroxyl propylene in the damping water composition is preferably 0.1 to 0.4 wt.%. If it is less than 0.1 wt.%, the surface tension of the damping water does not decrease sufficiently, whereas if it is over 4 wt.%, the viscosity coefficient of the damping water compound becomes high, which is not favorable.

Abstract: PURPOSE: To constantly fix the linear velocity by using only reproducing signals, by detecting deviation of recording signals from reference values of the maximum or minimum intervals, and by performing a rotation control based on the deviation.  
     CONSTITUTION: When a reproducing signal Sp is supplied to an input terminal 1, output signals S01 and S02, each of which has a polarity which is inverse to each other, are obtained from a limiter 2, and saw-tooth waves ST1 and ST2 whose levels increase at a prescribed gradient at the section where signals S01 and S02 are "0", appear from saw-tooth wave generating circuits 4a and 4b. At this time, the pulse width of the section where the signal S01 become "1", becomes wider, and that of the section where the signal S01 becomes "0", becomes narrower, and, when the signal S02 represents an inverse pulse width change, peak values V'd1 and V'd2 of the saw-tooth waves ST1 and ST2 are lowered or raised and an error signal is generated from a subtracting circuit 6. The reference voltage level from a voltage generating circuit 7 is raised by the signal and the error signal is controlled so that it becomes "0". Then, an output Vd of a peak holding circuit 5b at a level corresponding to the maximum inversion interval and a velocity reference voltage Vs are supplied to a level comparator 8, and thus, the velocity control signal is obtained.

Subsequently, the saw-tooth- wave is smoothed out and converted into direct current signals by means of a filter circuit 4 consisting of TC2. Then the said direct current signal is divided into two, one of them is inputted into a negative pole of IC4 in a comparison circuit 6, and the other is inputted into a positive pole of IC4 through a delay circuit 5. And then the direct current signal from the filter circuit 4 is compared with the direct current delay signal from the delay circuit 5, and an output circuit 3 is driven on the basis of the resultant of the said comparison, for example, a braking force is weakened with braking pressure lowered.
