IPC: H03K7/08
Filed: 1989-08-19
Abstract: PURPOSE:To decrease an IC chip and to reduce the cost by using a timer circuit to constitute a pulse width modulation PWM circuit. CONSTITUTION:When a PWM output 27 is at an H and the timer of a timer circuit 1c overflows, an L pulse is outputted to an output 2c, inputted to a frequency divider 26 to invert the PWM output 27 to an L level and to make the output of a NOR circuit 30 to an H level, a transmission gate 5c is opened and a DATA of a timer latch 3a is fed to the timer circuit 1c. Then the timer circuit 1c overflows by executing the operation of the DATA of the latch 3a to output an L pulse to the output 2c, and as soon as the PWM output 27 is inverted to an H, the transmission gate 5d is opened to supply the DATA of the timer latch 3b to the timer circuit 1c. Thus, one timer circuit is enough, the size of the IC chip is made small and an inexpensive IC is obtained.

Title: Vapor vessel
Inventor: SHIRAI MITSUGI
IPC: F27D7/02
Filed: 1983-11-16
Abstract: PURPOSE:To prevent outflow of vapor from a tunnel for carrying a treating object into and out of a vapor vessel and to recover throughly the vapor by providing a tunnel branching diagonally upward to the upper part of the tunnel and conducting the air flow introduced from said tunnel to the branch tunnel. CONSTITUTION:When vapor 1 is generated by heating a liquid 9, the vapor 1 ascends in a vapor vessel 5 and a boundary 10 between air and steam is made. On the other hand, a part of the vapor 1 flows to the outside of the vessel by passing through an inlet and outlet 6 and a tunnel 3. If the air flow of the momentum exceeding the momentum of the outflow vapor is created in the tunnel 2 in this stage, the air flow passes through a tunnel 4 and is discharged through an outflow port 12 and therefore the vapor 1 in the tunnel 3 is pushed back and the outflow of the vapor to the outside of the vessel is prevented. The tunnel 4 is extended diagonally upward toward the vessel 5 in order to conduct the air past the tunnel 2 as smoothly as possible to the upper part.

IPC: G01N17/00
Filed: 1982-12-08
Abstract: PURPOSE:To simplify the work and to remove a measuring error, by such constitution that charge is applied to a metal specimen in a necessary amount and the optimum values of condenser capacity, charging voltage and cut-off voltage are selected by the charge amount to perform the setting of a charge applying mechanism. CONSTITUTION:The max. voltage Emax of a charging circuit 1 passes the n- numbers of condenser selecting relays 10-a-10-n through a relay 5 to charge condensers 20a-2-n and the charge thereof is applied to a metal specimen 3 through a relay 6. The potential thereof is compared with the output Ecut of DA converter 13 by a comparator 7 and, when the potential of the metal 3 is low, output with an L-level is inputted to FF8 through an OR gate 12 while the relay 6 is opened to stop charge application. On the other hand, when Ecut is 9 times or more of Emax, a microcomputer 14 selects the condenser having the number next to the number of the condenser and, when Ecut is 0.9 times or less of Emax by repeating this operation, the relay other than the corresponding condenser is turned OFF. By this method, work is simplified and a measuring error is removed.

Abstract: PURPOSE:To simply bend a color coated steel reinforcement at predetermined angles and prevent a coated portion from peeling off by using, a rubber roller on whose metal surface a rubber layer, consisting of polyether polyurethane rubber whose hardness is 65-80 deg. (Shore hardness D), is formed. CONSTITUTION:Polyether polyurethane rubber is selected as a rubber layer, and the one whose hardness is 65-80 deg. (Shore hardness D) is used. Polyurethane rubber having a specific hardness is regulated by making polyether polyol and polyisocyanate react under the existence of a bridging agent. As for a method to bend a steel reinforcement 1 in color coating by means of rubber rollers, the steel reinforcement 1 is mounted on steel reinforcement receiving stands 4 between fixed fulcrum rollers 2 and rotatable dynamic point rollers 3, and rotation in arrow directions is conducted while the steel reinforcement 1 is being pressurized by means of dynamic point rollers 3 with fulcrum rollers 2 as centers. The steel reinforcement 1 is bend gradually in response to the rotation and movement of dynamic point rollers 3, and when it is bent at desired angles, the rotation of dynamic point rollers 3 is stopped. Thus, the coating of the steel reinforcement is not peeled off.

Title: Transfer material carrying member and image forming device using it
Inventor: SAKAKIBARA TEIGO
IPC: G03G15/01
Filed: 1991-08-01
Abstract: PURPOSE:To obtain an excellent image without causing a defect such as the unevenness of transfer or the omission of transfer by making a current value at the time when impressed voltage is 50V within a specified range as to the electric characteristic of a transfer material carrying member. CONSTITUTION:As to the electric characteristic of the transfer material carrying member 11, the current value at the time when the impressed voltage is 50V is under five times, desirably three times, as high as the current value at the time when the impressed voltage is 10V. Then, it is equal to or under 1/100, desirably 1/150, of the current value at the time when the impressed voltage is 4O00V. Namely, an electric current is not applied so much in a low electric field area but is applied by power function in a high electric field. As to current- voltage characteristic, by using the transfer carrying member 11 which is convex downward, a certain charge is held by electrostatically charging once, and a transfer paper is attracted and carried without trouble. Because of what is called a varistor effect, a transfer current is applied while holding a certain charge in the case of transferring toner on a transfer paper, thereby obtaining the excellent image.

Title: Pulsation pump
Inventor: TANISHITA KAZUO
IPC: F04B43/00
Filed: 1981-12-26
Abstract: PURPOSE:To eliminate sliding parts and simplify the construction, by making a member corresponding to the cylinder in conventional arrangement from special expansible material, by driving it to make expansion and contraction for itself, and thereby obtaining the pulsation pump action pressure without piston and plunger. CONSTITUTION:If an expansion/contraction motion is applied to a tube 1, for ex. consisting of porous polypropylene, by a reciprocative driver part 6, the liquid flows into the hollow 9 of the tube by opening a globe valve 7 forcedly from the A side because the tube 1 has an enlarged volume at its hollow 9 at the time of expansion to give a depressurized condition. Meanwhile, another globe valve 8 blocks the pipe 2 at its outgoing side, so that fluid corresponding to the amount of expansion of the tube 1 is taken in the hollow part 9. Then, tube 1 is compressed, the volume of hollow part 9 decreased, and the fluid flows out to the B side. Accordingly a pulsation pump is allowed to work with its full performance with much simple construction which gets rid of any sliding part.

Abstract: PURPOSE:To obtain a measured value without a sensitivity difference depending on the type of oil, by a method wherein the results of measurement obtained using two kinds of oil concentration measuring means providing different measuring methods are compared to estimate the type of oil and then, and a correction factor preset is selected. CONSTITUTION:First, the concentration of oil is measured with a first measuring means (a) which measures the concentration of oil in a sample water by the ultrasonic emulsion method and a second measuring means (b) using the fluorescence detection method different therefrom. Here, as the ratio of the two measured values varies with the type of oil, the type of oil contained in the sample water is estimated by an estimate means (c). Then, a correction factor of measuring sensitivity to various types of oil previously stored in a memory means (d) is selected according to the type of oil estimated to correct the measured value by the first measuring means (a). This provides a correct measured value of the concentration of oil in water free from sensitivity difference caused by the type of oil.
