Abstract: PURPOSE:To prevent the occurrence of poor conveyance, e.g. jam, oblique feed, by a method wherein strength characteristics of a sheet are detected in a conveyance passage by a detecting means, and based on the detecting result thereof, the following conveyance state of the sheet is decided. CONSTITUTION:An original 9 conveyed one by one from a hopper 12 to a conveyance passage 15 by means of a feed roller 18 is brought into contact with an actuator 1 and causes the rotational motion thereof. A displacement amount of the actuator 1 is detected by a sensor S1, and by means of an output therefrom, stiffness being strength characteristics of the original 9 is detected. An output from the sensor S1 is compared with preset allowable lower and upper limit values, and if the output is therebetween, the original 9 is guided to the regular conveyance passage of a circulation type automatic original feed device 11. Meanwhile, in the other case than the above, the strength characteristics are considered to be unsuitable for characteristics of the conveyance passages 15 and 16, the roller of a switch back conveyance passage 14, the curvature of a bent part, and the shape of a branch part, and the original 9 is moved backward. This constitution enables prevention of the occurrence of poor conveyance, e.g. jam, oblique conveyance.

Filed: 1984-06-22
Abstract: PURPOSE:To optimize an installation by detecting the remaining amt. of the flux in a hopper tank in a using stage or recovering stage and repeating the flux replenishment at a high or low rate in accordance with the detected remaining amt. thereof. CONSTITUTION:A blow tank 31 accepts the cycling flux from a recovering and gathering tank 25 and the replenishing flux from the hopper tank 26, mixes both fluxes and transports the mixture thereof to 5 pieces of welding line hopper tanks 37-41. Level gages 42-46 are provided to the tanks 37-41 which have the capacity equal to the amt. of the flux to be transported at one time by the tank 31. The tendency to an increase in the total amt. in the circulation system is judged if >=3 pieces of the gages 42-46 detect the flux. The replenishing flux is then charged at the low rate. The flux is conversely charged at the high rate if <=2 pieces of the gages detect the flux and the level gage 52 of the tank 25 does not detect the flux. The total amt. of the flux is optimized by the above- mentioned method, by which the optimization of the installation is made possible.

Patent JP-S6237027-A (JP)
Title: Small electric appliance
Inventor: GANTER WOLFGANG
IPC: G04C10/00
Filed: 1986-06-05
Abstract: A small electric device powered by solar cells and by a capacitive charge storage element has stable actuation assured during startup with an as yet uncharged capacitor. Startup problems are avoided by control of the power supply with a threshold value circuit that allows power to be supplied to device components when the components' minimum actuating voltage level has been attained at the capacitor. A deactuating voltage value of the threshold value circuit that is lower than the actuating voltage level prevents interruptions of operation similar to relaxation oscillation behavior due to temporarily increased actuating power requirements by causing deactivation of the components only if the capacitor voltage has dropped below a predetermined operational minimum. In this manner additional functions (such as radio watches with automatic hands setting devices or directional antennas, or ornamental pendulums or alarm or striking watches) which have components with higher acutating power requirements may be supplied without batteries by solar cells without having to overdimension the storage capacitor for the high startup load and thereby unnecessarily delay actuation of the device upon the exposure to radiation of the solar cells.

Title: Measuring method for concentrations of chelating agent, hydroxide ion and reducing agent in chemical copper plating solution
Inventor: HASEGAWA KIYOSHI
IPC: G01N31/16
Filed: 1991-05-31
Abstract: PURPOSE:To enable execution of simple and accurate measurement by a method wherein a sample solution of which titration by a water solution of the salt of heavy metal ions is ended is given the sulfite of an alkali metal and then titrated by the water solution of the salt of the heavy metal ions. CONSTITUTION:When a sample solution is titrated by a water solution of the salt of heavy metal ions, a chelating agent and hydroxide ions react sequentially with the heavy metal ions. The end point of the reaction of the chelating agent is a point A whereat pH begins to decrease sharply. The end point of the reaction of the hydroxide ions is an inflection point B whereat the sharp decrease of pH becomes gentle. The concentration of the chelating agent and that of the hydroxide ions are determined from the amounts of titration of these two end points of reaction. When the sulfite of an alkali metal is given to this sample solution, subsequently, a reducing agent which does not react in titration reacts with the sulfite and makes the hydroxide ions produced. By conducting second titration by the water solution of the salt of the heavy metal ions and by determining the quantity of hydroxide ions produced afresh, accordingly, the concentration of the reducing agent is determined.

CONSTITUTION:Plate groups 3 and 3' are installed adjacently to one another with a  container partitioning wall 1 provided between them. At the same time, welding electrodes 5 and 5' are made in contact with the back surfaces of electrode poles 4 and 4'.  After that, when electrodes 5 and 5' are energized while being pressed toward the wall 1, parts of the poles 4 and 4' which are in contact with one another with a penetrating  hole 2 provided between them are fused together, and a kind of elastic waves are  produced in accordance with the above fusion. A welding current is automatically cut  off by detecting thus produced elastic waves with a microphone 7, and operating relay  6 by amplifying the waves with an amplifier 8. Since a welding current is automatically  cut off by detecting elastic waves produce during the welding as mentioned above, the  welding can be performed by setting only such welding conditions as a current value  and a pressing pressure. Besides, since the current applied time can be automatically  adjusted to the optimum, the variation of the fusing intensity is reduced.
