Title: Controller for chopper
Inventor: HORIUCHI MICHIMASA
IPC: H02P7/29
Filed: 1981-10-23
Abstract: PURPOSE:To always utilize the controlling range of a chopper to the maximum limit by controlling next ON signal not to input within commutation time determined from the current value at the time of applying an OFF signal. CONSTITUTION:Sigals obtained by converting a motor current IM and a command value IP to digital values are inputted according to an interrupt signal at  each operating period of a chopper from an oscillator OSC to calculate a deviation epsilon, and a current flowing time DUTY is outputted in response to the deviation. On the other hand, the commutating time in response to the digital value  of the motor current IM is read out from a data table, and the maximum current flowing time obtained by subtracting the chopper period TCH by the read-out commutating time is outputted. In this manner, the controlling range of the chopper can be utilized most effectively irrespective of the motor current with a simple structure.

Title: Method for separating hydrocarbon blend
Inventor: SUZUKI TERUTOSHI
IPC: C07C11/167
Filed: 1986-07-18
Abstract: PURPOSE:To separate impurities from a hydrocarbon blend while saving energy in a degassing column of the next process and miniaturizing devices, by equipping one distillation column with an extractive distillation zone and an ordinary distillation zone to reduce a feed amount of a selectively extracting solvent. CONSTITUTION:For example, in separating and removing impurities such as a small amount of 1,2-butadiene, etc., contained in crude butadiene, a selectively extracting solvent (e.g. DMF) is fed from a line 2 to the middle plate of an extractive distillation column A, an ordinary distillation zone having >=20 plates (preferably 20-90 plates) is set on the feed plate and an extractive distillation zone having >=5 plates (preferably 20-90 plates) is laid under the feed plate to carry out extraction. The impurities are roughly removed by the extractive distillation part and further reduced to a very small concentration efficiently by ordinary distillation. EFFECT:Since the feed amount of a selectively extracting solvent can be extremely reduced, especially an ordinary distillation column can be lessened and a degassing column is also miniaturized.

IPC: B21D53/28
Filed: 1985-07-31
Abstract: PURPOSE:To enable an amount of cut in the radial direction of a major axis side to be equalized to that of a minor axis side, by cutting a swell direction-external side surface of a flange part in the direction of plate thickness and forming a tooth unit decreasing a tooth thickness of each tooth profile part smaller than the plate thickness of an intermediate base structure. CONSTITUTION:The method of manufacture, pressing an aluminum plate to swell its peripheral part in a ring shape to one side in the direction of plate thickness for the central part while forming a ring-shaped flange part 11 in the peripheral part, forms an intermediate base structure 1 providing many tooth profile parts 12 in said flange part 11 and having a bowl-shaped section further with the oval-shaped front. And the method, next cutting said intermediate base structure 1 in its flange part 11 further its swell direction-external side surface 11a to the direction of plate thickness, forms a tooth unit 2 decreasing a tooth thickness H in each tooth profile part 12 smaller than a plate thickness T of the intermediate base structure 1. Accordingly, the method, enabling an amount of cut in the radial direction in a major axis side to be equalized to an amount of cut in the radial direction in a minor axis side, can eliminate a decrease of strength in a major axis side tooth body portion while equalize the strength of each tooth unit 2.

Title: Reinforced concrete pillar and its reinforcing method
Inventor: HARADA TETSUO
IPC: E04C5/08
Filed: 1995-06-14
Abstract: PURPOSE: To enhance vertical strength of a newly constructed or existing concrete pillar by using PC steel materials in multiple stages horizontally and tensing them and by giving horizontal compressive stress to inside concrete as prestress. CONSTITUTION: In case of a newly constructed pillar, horizontal compressive stress is generated by tightening neighbouring concrete in the centripetal direction by using PC steel materials 5 formed with, for example, ring one in multiple stages and tensing them in intervals of horizontal reinforcing bars of the pillar. In this case, end parts of the PC steel materials 5 are exposed from the concrete, tensed by a hydraulic jack, or the like after the deposited concrete is hardened and fixed on the concrete surface. Consequently, when a vertical load is added on the pillar 1 and vertical compressive stress is generated, it becomes triaxial stress, and vertical strength is strengthened larger than in the case of only conventional vertical stress.  Even in case of strengthening an existing concrete column, the PC steel materials 5 treated with rust preventives are wound around its outer periphery and tensed, and compressive stress in the centripetal direction is given to the inside concrete.

Abstract: PURPOSE:To provide an analog timepiece which can accurately indicate the present time when the mode is returned to a lock mode even when the mode is wrongly switched to a time adjusting mode by starting time adjustment by operating a time adjusting switch after the mode is switched to the time adjusting mode. CONSTITUTION:When an up-key 142 and down-key 143 are operated while a mode change-over switch 141 designates a set mode, a control circuit 3 stop hands indicating the present time. When the up-key 142 is operated in a 'time set-time mode', the circuit 3 rotates a short hand 8 clockwise by one-hour amount and, when the down-key 143 is operated, rotates a long hand 9 counterclockwise by one-hour amount. In the case where the indicating position of the long hand 9 is not correct minute's position, the circuit 3 moves the hand 9 counterclockwise to the correct minute's position and any fraction sum of seconds is discarded. When the keys 142 and 143 are operated in a 'time set- minute mode', the hand 9 is moved to the position of the present minute or the just-passed minute.
